| Pricing Supplement dated April , 2018 Filed Pursuant to Rule 424(b)(2) Registration Statement No. 333-212571 Barclays Bank PLC Trigger Autocallable Notes |

Linked to the S&P 500 ® Index due on or about April 15, 2020

Investment Description

Trigger Autocallable Notes (the “Notes”) are unsecured and unsubordinated debt obligations issued by Barclays Bank PLC (the “Issuer”) linked to the performance of the S&P 500 ® Index (the “Underlying”). The Issuer will automatically call the Notes if the Closing Level of the Underlying on any Observation Date (quarterly, beginning after six months) is greater than or equal to the Closing Level of the Underlying on the Trade Date (the “Initial Underlying Level”). If the Notes are automatically called, the Issuer will pay you a Call Price equal to the principal amount of your Notes plus a Call Return, and no further amounts will be owed to you under the Notes. The Call Return increases based on the per annum Call Return Rate for each additional quarter the Notes remain outstanding. If the Notes are not automatically called and the Closing Level of the Underlying on the Final Valuation Date (the “Final Underlying Level”) is greater than or equal to the specified Downside Threshold, the Issuer will pay you a cash payment at maturity equal to the principal amount of your Notes. However, if the Final Underlying Level is less than the Downside Threshold, the Issuer will pay you a cash payment at maturity that is less than the principal amount, if anything, resulting in a percentage loss on your investment equal to the negative Underlying Return. In this case, you will have full downside exposure to the Underlying from the Initial Underlying Level to the Final Underlying Level, and could lose all of your initial investment. Investing in the Notes involves significant risks. You may lose a significant portion or all of your initial investment. The Final Underlying Level is observed relative to the Downside Threshold only on the Final Valuation Date, and the contingent repayment of principal applies only if you hold the Notes to maturity. Generally, the higher the Call Return Rate on a Note, the greater the risk of loss on that Note. Your return potential on the Notes is limited to any Call Return paid on the Notes, and you will not participate in any appreciation of the Underlying. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of Barclays Bank PLC and is not guaranteed by any third party. If Barclays Bank PLC were to default on its payment obligations or become subject to the exercise of any U.K. Bail-in Power (as described on page PS-4 of this pricing supplement) by the relevant U.K. resolution authority, you might not receive any amounts owed to you under the Notes. See “Consent to U.K. Bail-in Power” in this pricing supplement and “Risk Factors” in the accompanying prospectus supplement.

| q Automatic Call: The Issuer will automatically call the Notes
if the Closing Level of the Underlying on any Observation Date (quarterly, beginning after six months) is greater than or equal
to the Initial Underlying Level. If the Notes are automatically called, the Issuer will pay you a Call Price equal to the principal
amount of your Notes plus a Call Return, and no further amounts will be owed to you under the Notes. The Call Return increases
based on the per annum Call Return Rate for each additional quarter the Notes remain outstanding. q Downside Exposure with Contingent Repayment of Principal at Maturity: If the Notes are not automatically called and the Final Underlying Level is greater than or equal to the Downside Threshold, the
Issuer will repay the principal amount at maturity. However, if the Final Underlying Level is less than the Downside Threshold,
the Issuer will repay less than the full principal amount at maturity, if anything, resulting in a percentage loss on your investment
equal to the negative Underlying Return. The Final Underlying Level is observed relative to the Downside Threshold only on the
Final Valuation Date, and the contingent repayment of principal applies only if you hold the Notes to maturity. Any payment on
the Notes, including any repayment of principal, is subject to the creditworthiness of Barclays Bank PLC. |

Additional Information Regarding Our Estimated Value of the Notes

Our internal pricing models take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize, typically including volatility, interest rates and our internal funding rates. Our internal funding rates (which are our internally published borrowing rates based on variables, such as market benchmarks, our appetite for borrowing and our existing obligations coming to maturity) may vary from the levels at which our benchmark debt securities trade in the secondary market. Our estimated value on the Trade Date is based on our internal funding rates. Our estimated value of the Notes might be lower if such valuation were based on the levels at which our benchmark debt securities trade in the secondary market.

Our estimated value of the Notes on the Trade Date is expected to be less than the initial issue price of the Notes. The difference between the initial issue price of the Notes and our estimated value of the Notes is expected to result from several factors, including any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost that we may incur in hedging our obligations under the Notes, and estimated development and other costs that we may incur in connection with the Notes.

Our estimated value on the Trade Date is not a prediction of the price at which the Notes may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the Notes in the secondary market. Subject to normal market and funding conditions, Barclays Capital Inc. or another affiliate of ours intends to offer to purchase the Notes in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the Trade Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value on the Trade Date for a temporary period expected to be approximately five months after the initial issue date of the Notes because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes that we will no longer expect to incur over the term of the Notes. We made such discretionary election and determined this temporary reimbursement period on the basis of a number of factors, which may include the tenor of the Notes and/or any agreement we may have with the distributors of the Notes. The amount of our estimated costs that we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the initial issue date of the Notes based on changes in market conditions and other factors that cannot be predicted.

We urge you to read the “Key Risks” beginning on page PS-8 of this pricing supplement.

You may revoke your offer to purchase the Notes at any time prior to the Trade Date. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to their Trade Date. In the event of any changes to the terms of the Notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.

Consent to U.K. Bail-in Power

Notwithstanding any other agreements, arrangements or understandings between us and any holder of the Notes, by acquiring the Notes, each holder of the Notes acknowledges, accepts, agrees to be bound by and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority.

Under the U.K. Banking Act 2009, as amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power in circumstances in which the relevant U.K. resolution authority is satisfied that the resolution conditions are met. These conditions include that a U.K. bank or investment firm is failing or is likely to fail to satisfy the Financial Services and Markets Act 2000 (the “FSMA”) threshold conditions for authorization to carry on certain regulated activities (within the meaning of section 55B FSMA) or, in the case of a U.K. banking group company that is an European Economic Area (“EEA”) or third country institution or investment firm, that the relevant EEA or third country relevant authority is satisfied that the resolution conditions are met in respect of that entity.

The U.K. Bail-in Power includes any write-down, conversion, transfer, modification and/or suspension power, which allows for (i) the reduction or cancellation of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Notes; (ii) the conversion of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Notes into shares or other securities or other obligations of Barclays Bank PLC or another person (and the issue to, or conferral on, the holder of the Notes such shares, securities or obligations); and/or (iii) the amendment or alteration of the maturity of the Notes, or amendment of the amount of interest or any other amounts due on the Notes, or the dates on which interest or any other amounts become payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the Notes solely to give effect to the exercise by the relevant U.K. resolution authority of such U.K. Bail-in Power. Each holder of the Notes further acknowledges and agrees that the rights of the holders of the Notes are subject to, and will be varied, if necessary, solely to give effect to, the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. For the avoidance of doubt, this consent and acknowledgment is not a waiver of any rights holders of the Notes may have at law if and to the extent that any U.K. Bail-in Power is exercised by the relevant U.K. resolution authority in breach of laws applicable in England.

For more information, please see “Key Risks—You may lose some or all of your investment if any U.K. bail-in power is exercised by the relevant U.K. resolution authority” in this pricing supplement as well as “U.K. Bail-in Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail could materially adversely affect the value of the securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

Investor Suitability

The Notes may be suitable for you if: ¨ You fully understand the risks inherent in an investment in the Notes, including the risk of loss of your entire initial investment. ¨ You can tolerate a loss of a significant portion or all of your initial investment, and you are willing to make an investment that may have the full downside market risk of the Underlying. ¨ You believe the Closing Level of the Underlying is likely to be greater than or equal to the Initial Underlying Level on any one of the Observation Dates, and, if it is not, you can tolerate not receiving a positive return on the Notes. ¨ You believe the Final Underlying Level is not likely to be less than the Downside Threshold and, if it is, you can tolerate a loss of a significant portion or all of your investment. ¨ You understand and accept that you will not participate in any appreciation of the Underlying, which may be significant, and that your return potential on the Notes is limited to any Call Return paid on the Notes. ¨ You are willing and able to hold Notes that will be called on the earliest Observation Date (quarterly, beginning after six months) on which the Closing Level of the Underlying is greater than or equal to the Initial Underlying Level, and you are otherwise willing and able to hold the Notes to maturity and accept that there may be little or no secondary market for the Notes. ¨ You would be willing to invest in the Notes if the Call Return Rate were set equal to the minimum Call Return Rate specified on the cover of this pricing supplement (the actual Call Return Rate will be set on the Trade Date). ¨ You can tolerate fluctuations in the price of the Notes prior to maturity that may be similar to or exceed the downside fluctuations in the level of the Underlying. ¨ You do not seek current income from this investment, and you are willing to forgo any dividends paid on the securities composing the Underlying. ¨ You understand and are willing to accept the risks associated with the Underlying. ¨ You are willing and able to assume the credit risk of Barclays Bank PLC, as issuer of the Notes, for all payments under the Notes and understand that if Barclays Bank PLC were to default on its payment obligations or become subject to the exercise of any U.K. Bail-in Power, you might not receive any amounts due to you under the Notes, including any repayment of principal. The Notes may not be suitable for you if: ¨ You do not fully understand the risks inherent in an investment in the Notes, including the risk of loss of your entire initial investment. ¨ You cannot tolerate the loss of a significant portion or all of your initial investment, or you are not willing to make an investment that may have the full downside market risk of the Underlying. ¨ You do not believe the Closing Level of the Underlying is likely to be greater than or equal to the Initial Underlying Level on any one of the Observation Dates, or you cannot tolerate not receiving a positive return on the Notes. ¨ You believe the Final Underlying Level is likely to be less than the Downside Threshold, which could result in a total loss of your initial investment. ¨ You seek an investment that participates in the full appreciation of the Underlying and whose return is not limited to any Call Return paid on the Notes. ¨ You are unwilling or unable to hold Notes that will be called on the earliest Observation Date (quarterly, beginning after six months) on which the Closing Level of the Underlying is greater than or equal to the Initial Underlying Level, or you are unable or unwilling to hold the Notes to maturity and seek an investment for which there will be an active secondary market. ¨ You cannot tolerate fluctuations in the price of the Notes prior to maturity that may be similar to or exceed the downside fluctuations in the level of the Underlying. ¨ You would be unwilling to invest in the Notes if the Call Return Rate were set equal to the minimum Call Return Rate specified on the cover of this pricing supplement (the actual Call Return Rate will be set on the Trade Date). ¨ You seek current income from this investment, or you would prefer to receive any dividends paid on the securities composing the Underlying. ¨ You do not understand or are not willing to accept the risks associated with the Underlying. ¨ You prefer the lower risk, and therefore accept the potentially lower returns, of fixed income investments with comparable maturities and credit ratings that bear interest at a prevailing market rate. ¨ You are not willing or are unable to assume the credit risk of Barclays Bank PLC, as issuer of the Notes, for all payments due to you under the Notes, including any repayment of principal.

The suitability considerations identified above are not exhaustive. Whether or not the Notes are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the suitability of an investment in the Notes in light of your particular circumstances. You should also review carefully the “Key Risks” beginning on page PS-8 of this pricing supplement and the “Risk Factors” beginning on page S-7 of the prospectus supplement for risks related to an investment in the Notes.

the Issuer will repay less than the full principal amount at maturity, if anything, resulting in a percentage loss on
your investment equal to the decline of the Underlying from the Trade Date to the Final Valuation Date. Accordingly, the
payment at maturity per Note would be calculated as follows: $10 + ($10 × Underlying Return) If the Final Underlying Level is less than the Downside
Threshold, your principal is fully exposed to the decline in the Underlying, and you will lose a significant portion or

4 If the Underlying is discontinued or if the sponsor of the Underlying fails to publish the Underlying, the Calculation Agent may select a successor underlying or, if no successor underlying is available, will calculate the value to be used as the Closing Level of the Underlying. In addition, the Calculation Agent will calculate the value to be used as the Closing Level of the Underlying in the event of certain changes in or modifications to the Underlying.

Investment Timeline

Trade Date:	The Closing Level of the Underlying (the Initial Underlying Level) is observed, the Call Return Rate is set and the Downside Threshold is determined.
●
Quarterly (beginning after six months):	The Issuer will automatically call the Notes if the Closing Level
of the Underlying on any Observation Date (quarterly, beginning after six months) is greater than or equal to the Initial Underlying
Level. If the Notes are automatically called, the Issuer will pay you
a Call Price equal to the principal amount of your Notes plus a Call Return, and no further amounts will be owed to you
under the Notes. The Call Return increases based on the per annum Call Return Rate for each additional quarter the Notes remain
outstanding.
●
Maturity Date:	The Final Underlying Level is determined on the Final Valuation
Date. If
the Notes are not automatically called and the Final Underlying Level is greater than or equal to the Downside Threshold ,
the Issuer will repay the full principal amount at maturity of $10 per Note. If
the Notes are not automatically called and the Final Underlying Level is less than the Downside Threshold , the Issuer
will repay less than the full principal amount at maturity, if anything, resulting in a percentage loss on your investment equal
to the decline of the Underlying from the Trade Date to the Final Valuation Date. Accordingly, the payment at maturity per Note
would be calculated as follows: $10 + ($10 × Underlying Return) If the Final Underlying Level is less than the
Downside Threshold, your principal is fully exposed to the decline in the Underlying, and you will lose a significant portion
or all of the principal amount of the Notes at maturity. Any payment on the Notes, including any repayment of principal, is subject
to the creditworthiness of Barclays Bank PLC and is not guaranteed by any third party.

Investing in the Notes involves significant risks. You may lose a significant portion or all of your initial investment. The Final Underlying Level is observed relative to the Downside Threshold only on the Final Valuation Date, and the contingent repayment of principal applies only if you hold the Notes to maturity. Generally, the higher the Call Return Rate on a Note, the greater the risk of loss on that Note. Your return potential on the Notes is limited to any Call Return paid on the Notes, and you will not participate in any appreciation of the Underlying. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of Barclays Bank PLC and is not guaranteed by any third party. If Barclays Bank PLC were to default on its payment obligations or become subject to the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority, you might not receive any amounts owed to you under the Notes.

Key Risks

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Underlying or the securities composing the Underlying. Some of the risks that apply to an investment in the Notes are summarized below, but we urge you to read the more detailed explanation of risks relating to the Notes generally in the “Risk Factors” section of the prospectus supplement. You should reach an investment decision only after you have carefully considered with your advisors the suitability of an investment in the Notes in light of your particular circumstances.

¨ You risk losing a significant portion or all of your principal — The Notes differ from ordinary debt securities in that the Issuer will not necessarily repay the full principal amount of the Notes at maturity. If the Notes are not automatically called, the Issuer will pay you the principal amount of your Notes only if the Final Underlying Level is greater than or equal to the Downside Threshold and will make such payment only at maturity. If the Notes are not automatically called and the Final Underlying Level is less than the Downside Threshold, you will be exposed to the full negative Underlying Return and the Issuer will repay less than the full principal amount of the Notes at maturity, if anything, resulting in a percentage loss on your investment equal to the decline of the Underlying from the Trade Date to the Final Valuation Date. Accordingly, you may lose a significant portion or all of your principal.

¨ Your return potential on the Notes is limited to any Call Return paid on the Notes, and you will not participate in any appreciation of the Underlying — The return potential of the Notes is limited to the pre-specified per annum Call Return Rate, regardless of any appreciation of the Underlying, which may be significant. In addition, because the Call Return increases based on the per annum Call Return Rate for each additional quarter the Notes remain outstanding, the Call Price payable on the first Observation Date is less than the Call Price payable for later Observation Dates. Therefore, if the Notes are automatically called on an earlier Observation Date, you will receive a lower Call Price than if the Notes were called on a later Observation Date. If the Notes are not automatically called, you may be subject to the decline in the level of the Underlying even though you will not participate in any of the Underlying’s appreciation. As a result, the return on an investment in the Notes could be less than the return on a direct investment in the securities composing the Underlying.

¨ Contingent repayment of principal applies only at maturity — You should be willing to hold your Notes to maturity. The market value of the Notes may fluctuate between the date you purchase them and the Final Valuation Date. If you are able to sell your Notes prior to maturity in the secondary market, if any, you may have to sell them at a loss relative to your initial investment even if at that time the level of the Underlying is greater than the Downside Threshold.

¨ Reinvestment risk — If your Notes are automatically called early, the holding period over which you would receive the per annum Call Return Rate could be as short as approximately six months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes in a comparable investment with a similar level of risk in the event the Notes are automatically called prior to the Maturity Date. The likelihood that the Notes will be automatically called prior to the Maturity Date is highest earlier in their term. Generally, the longer the Notes remain outstanding, the less likely it is that the Notes will be automatically called, due to the decline in the level of the Underlying that has caused the Notes not to be automatically called on an earlier Observation Date and the shorter time remaining for the level of the Underlying to increase to or above the Initial Underlying Level on a subsequent Observation Date. If the Notes are not automatically called, you might be exposed to the full decline in the Underlying.

¨ A higher Call Return Rate and/or a lower Downside Threshold may reflect greater expected volatility of the Underlying, which is generally associated with a greater risk of loss — Volatility is a measure of the degree of variation in the level of the Underlying over a period of time. The greater the expected volatility of the Underlying at the time the terms of the Notes are set, the lower the expectation is at that time that the Notes will be automatically called for the applicable Call Price and the greater the expectation is that you may lose a significant portion or all of your principal at maturity. In addition, the economic terms of the Notes, including the Call Return Rate and the Downside Threshold, are based, in part, on the expected volatility of the Underlying at the time the terms of the Notes are set, where higher expected volatility will generally be reflected in a higher Call Return Rate than the fixed rate we would pay on conventional debt securities of the same maturity and/or on otherwise comparable securities and/or a lower Downside Threshold as compared to otherwise comparable securities. Accordingly, a higher Call Return Rate will generally be indicative of a greater risk of loss while a lower Downside Threshold does not necessarily indicate that the Notes have a greater likelihood of being automatically called for the applicable Call Price or returning your principal at maturity. However, the Underlying’s volatility can change significantly over the term of the Notes. The level of the Underlying could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Underlying and the potential loss of a significant portion or all of your principal at maturity.

¨ No interest payments — The Issuer will not make periodic interest payments on the Notes.

¨ Credit of Issuer — The Notes are unsecured and unsubordinated debt obligations of the Issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the Notes, including any repayment of principal, is subject to the ability of Barclays Bank PLC to satisfy its obligations as they come due and is not guaranteed by any third party. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the Notes and, in the event Barclays Bank PLC were to default on its obligations, you might not receive any amount owed to you under the terms of the Notes.

¨ You may lose some or all of your investment if any U.K. Bail-in Power is exercised by the relevant U.K. resolution authority — Notwithstanding any other agreements, arrangements or understandings between Barclays Bank PLC and any holder of the Notes, by acquiring the Notes, each holder of the Notes acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority as set forth under “Consent to U.K. Bail-in Power” in this pricing supplement. Accordingly, any U.K. Bail-in Power may be exercised in such a manner as to result in you and other holders of the Notes losing all or a part of the value of your investment in the Notes or receiving a different security from the Notes, which may be worth significantly less than the Notes and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise the U.K. Bail-in Power without providing any advance notice to, or requiring the consent of, the holders of the Notes. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes will not be a default or an Event of Default (as each term is defined in the indenture) and the trustee will not be liable for any action that the trustee takes, or abstains from taking, in either case, in accordance with the exercise of the U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes. See “Consent to U.K. Bail-in Power” in this pricing supplement as well as “U.K. Bail-in

Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail could materially adversely affect the value of the securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

¨ Owning the Notes is not the same as owning the securities composing the Underlying — The return on your Notes may not reflect the return you would realize if you actually owned the securities composing the Underlying. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the securities composing the Underlying would have.

¨ The Underlying reflects the price return of the securities composing the Underlying, not the total return — The return on the Notes is based on the performance of the Underlying, which reflects changes in the market prices of the securities composing the Underlying. The Underlying is not a “total return” index that, in addition to reflecting those price returns, would also reflect dividends paid on the securities composing the Underlying. Accordingly, the return on the Notes will not include such a total return feature.

¨ Dealer incentives — We, the Agents and affiliates of the Agents act in various capacities with respect to the Notes. The Agents and various affiliates may act as a principal, agent or dealer in connection with the Notes. Such Agents, including the sales representatives of UBS Financial Services Inc., will derive compensation from the distribution of the Notes and such compensation may serve as an incentive to sell these Notes instead of other investments. We will pay compensation as specified on the cover of this pricing supplement to the Agents in connection with the distribution of the Notes, and such compensation may be passed on to affiliates of the Agents or other third party distributors.

¨ There may be little or no secondary market for the Notes — The Notes will not be listed on any securities exchange. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to make a secondary market for the Notes but are not required to do so, and may discontinue any such secondary market making at any time, without notice. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC are willing to buy the Notes. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

¨ Potentially inconsistent research, opinions or recommendations by Barclays Capital Inc., UBS Financial Services Inc. or their respective affiliates — Barclays Capital Inc., UBS Financial Services Inc. or their respective affiliates and agents may publish research from time to time on financial markets and other matters that may influence the value of the Notes, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Notes. Any research, opinions or recommendations expressed by Barclays Capital Inc., UBS Financial Services Inc. or their respective affiliates or agents may not be consistent with each other and may be modified from time to time without notice. You should make your own independent investigation of the merits of investing in the Notes and the Underlying.

¨ Potential Barclays Bank PLC impact on value — Trading or transactions by Barclays Bank PLC or its affiliates in the securities composing the Underlying and/or over-the-counter options, futures or other instruments with returns linked to the performance of the Underlying or the securities composing the Underlying may adversely affect the level of the Underlying and, therefore, the market value of the Notes.

¨ Many economic and market factors will impact the value of the Notes — Structured notes, including the Notes, can be thought of as securities that combine a debt instrument with one or more options or other derivative instruments. As a result, the factors that influence the values of debt instruments and options or other derivative instruments will also influence the terms and features of the Notes at issuance and their value in the secondary market. Accordingly, in addition to the level of the Underlying on any day, the value of the Notes will be affected by a number of economic and market factors that may either offset or magnify each other, including:

¨ the expected volatility of the Underlying and the securities composing the Underlying;

¨ the time to maturity of the Notes;

¨ the market prices of, and dividend rates on, the securities composing the Underlying;

¨ interest and yield rates in the market generally;

¨ supply and demand for the Notes;

¨ a variety of economic, financial, political, regulatory and judicial events; and

¨ our creditworthiness, including actual or anticipated downgrades in our credit ratings.

¨ The estimated value of your Notes is expected to be lower than the initial issue price of your Notes — The estimated value of your Notes on the Trade Date is expected to be lower, and may be significantly lower, than the initial issue price of your Notes. The difference between the initial issue price of your Notes and the estimated value of the Notes is expected as a result of certain factors, such as any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost that we may incur in hedging our obligations under the Notes, and estimated development and other costs that we may incur in connection with the Notes.

¨ The estimated value of your Notes might be lower if such estimated value were based on the levels at which our debt securities trade in the secondary market — The estimated value of your Notes on the Trade Date is based on a number of variables, including our internal funding rates. Our internal funding rates may vary from the levels at which our benchmark debt securities trade in the secondary market. As a result of this difference, the estimated values referenced above might be lower if such estimated values were based on the levels at which our benchmark debt securities trade in the secondary market. Also, this difference in funding rate as well as certain factors, such as sales commissions, selling concessions, estimated costs and profits mentioned below, reduces the economic terms of the Notes to you.

¨ The estimated value of the Notes is based on our internal pricing models, which may prove to be inaccurate and may be different from the pricing models of other financial institutions — The estimated value of your Notes on the Trade Date is based on our internal pricing models, which take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize. These variables and assumptions are not evaluated or verified on an independent basis. Further, our pricing models may be different from other financial institutions’ pricing models and the methodologies used by us to estimate the value of the Notes may not be consistent with those of other financial institutions that may be purchasers or sellers of Notes in the secondary market. As a result, the secondary market price of your Notes may be materially different from the estimated value of the Notes determined by reference to our internal pricing models.

¨ The estimated value of your Notes is not a prediction of the prices at which you may sell your Notes in the secondary market, if any, and such secondary market prices, if any, will likely be lower than the initial issue price of your Notes and may be lower than the estimated value of your Notes — The estimated value of the Notes will not be a prediction of the prices at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions (if they are willing to purchase, which they are not obligated to do). The price at which you may be able to sell your Notes in the secondary market at any time will be influenced by many factors that cannot be predicted, such as market conditions, and any bid and ask spread for similar sized trades, and may be substantially less than our estimated value of the Notes. Further, as secondary market prices of your Notes take into account the levels at which our debt securities trade in the secondary market, and do not take into account our various costs related to the Notes such as fees, commissions, discounts, and the costs of hedging our obligations under the Notes, secondary market prices of your Notes will likely be lower than the initial issue price of your Notes. As a result, the price at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions, if any, will likely be lower than the price you paid for your Notes, and any sale prior to the Maturity Date could result in a substantial loss to you.

¨ The temporary price at which we may initially buy the Notes in the secondary market and the value we may initially use for customer account statements, if we provide any customer account statements at all, may not be indicative of future prices of your Notes — Assuming that all relevant factors remain constant after the Trade Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market (if Barclays Capital Inc. makes a market in the Notes, which it is not obligated to do) and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value of the Notes on the Trade Date, as well as the secondary market value of the Notes, for a temporary period after the initial issue date of the Notes. The price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market and the value that we may initially use for customer account statements may not be indicative of future prices of your Notes. Please see “Additional Information Regarding Our Estimated Value of the Notes” on page PS-3 for further information.

¨ We and our affiliates may engage in various activities or make determinations that could materially affect your Notes in various ways and create conflicts of interest — We and our affiliates play a variety of roles in connection with the issuance of the Notes, as described below. In performing these roles, our and our affiliates’ economic interests are potentially adverse to your interests as an investor in the Notes.

In connection with our normal business activities and in connection with hedging our obligations under the Notes, we and our affiliates make markets in and trade various financial instruments or products for our accounts and for the account of our clients and otherwise provide investment banking and other financial services with respect to these financial instruments and products. These financial instruments and products may include securities, derivative instruments or assets that may relate to the Underlying or its components. In any such market making, trading and hedging activity, investment banking and other financial services, we or our affiliates may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the Notes. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the Notes into account in conducting these activities. Such market making, trading and hedging activity, investment banking and other financial services may negatively impact the value of the Notes.

In addition, the role played by Barclays Capital Inc., as the agent for the Notes, could present significant conflicts of interest with the role of Barclays Bank PLC, as issuer of the Notes. For example, Barclays Capital Inc. or its representatives may derive compensation or financial benefit from the distribution of the Notes and such compensation or financial benefit may serve as an incentive to sell the Notes instead of other investments. Furthermore, we and our affiliates establish the offering price of the Notes for initial sale to the public, and the offering price is not based upon any independent verification or valuation.

In addition to the activities described above, we will also act as the Calculation Agent for the Notes. As Calculation Agent, we will determine any values of the Underlying and make any other determinations necessary to calculate any payments on the Notes. In making these determinations, we may be required to make discretionary judgments, including determining whether a market disruption event has occurred on any date that the value of the Underlying is to be determined; if the Underlying is discontinued or if the sponsor of the Underlying fails to publish the Underlying, selecting a successor underlying or, if no successor underlying is available, determining any value necessary to calculate any payments on the Notes; and calculating the value of the Underlying on any date of determination in the event of certain changes in or modifications to the Underlying. In making these discretionary judgments, our economic interests are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes.

¨ The U.S. federal income tax consequences of an investment in the Notes are uncertain — There is no direct legal authority regarding the proper U.S. federal income tax treatment of the Notes, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the Notes are uncertain, and the IRS or a court might not agree with the treatment of the Notes as prepaid forward contracts, as described under “What Are the Tax Consequences of an Investment in the Notes?” below. If the IRS were successful in asserting an alternative treatment for the Notes, the tax consequences of the ownership and disposition of the Notes could be materially and adversely affected. In addition, in 2007 the Treasury Department and the IRS released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. Any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Notes, possibly with retroactive effect. You should review carefully the sections of the accompanying prospectus supplement entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Forward or Derivative Contracts” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders,” and consult your tax advisor regarding the U.S. federal tax consequences of an investment in the Notes (including possible alternative treatments and the issues presented by the 2007 notice), as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Hypothetical Examples

Hypothetical terms only. Actual terms may vary. See the cover page for actual offering terms.

The examples below illustrate the payment upon a call or at maturity for a $10 principal amount Note on a hypothetical offering of the Notes under various scenarios, with the assumptions set forth below.* You should not take these examples as an indication or assurance of the expected performance of the Notes. The examples below do not take into account any tax consequences from investing in the Notes. Numbers appearing in the examples below have been rounded for ease of analysis.

Term:	Approximately two years (unless called earlier)
Hypothetical Call Return Rate:	8.85% per annum (or 2.2125% per quarter) (the minimum Call Return Rate that may be set on the Trade Date)
Hypothetical Initial Underlying Level:	100.00
Hypothetical Downside Threshold:	75.00 (75.00% of the hypothetical Initial Underlying Level)
Observation Dates:	Quarterly, beginning after six months, as set forth under the “Observation Date” column of the table “Indicative Terms—Call Return/Call Return Rate” in this pricing supplement.

*Terms used for purposes of these hypothetical examples may not represent the actual Call Return Rate per annum, Initial Underlying Level or Downside Threshold. The actual Call Return Rate per annum will be set on the Trade Date. The hypothetical Initial Underlying Level of 100.00 has been chosen for illustrative purposes only and may not represent a likely actual Initial Underlying Level. The actual Initial Underlying Level and resulting Downside Threshold will be based on the Closing Level of the Underlying on the Trade Date. For historical Closing Levels of the Underlying, please see the historical information set forth under the section titled “S&P 500 ® Index” below. We cannot predict the Closing Level of the Underlying on any day during the term of the Notes, including on any Observation Date.

Example 1 — Notes Are Automatically Called on the First Observation Date

| Date | Closing
Level | Payment
(per Note) |
| --- | --- | --- |
| First Observation Date | 110.00 | Closing level of Underlying at or above Initial Underlying Level; Notes are automatically called; Issuer pays the Call
Price applicable to the first Observation Date on the related Call Settlement Date. |

Call Price (per Note):	$10.4425
Total Return:	4.425%

Because the Closing Level of the Underlying is greater than or equal to the Initial Underlying Level on the first Observation Date (which is approximately six months after the Trade Date), the Notes are automatically called on that Observation Date. The Issuer will pay you on the related Call Settlement Date a Call Price of $10.4425 per Note for a total return of 4.425% on the Notes. No further amounts will be owed to you under the Notes.

As indicated in this example, any positive return on your Notes will not exceed the Call Price with respect to the applicable Observation Date, regardless of any appreciation in the Underlying, which may be significant.

Example 2 — Notes Are Automatically Called on the Final Valuation Date

| Date | Closing
Level | Payment
(per Note) |
| --- | --- | --- |
| First Observation Date | 85.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Second Observation Date | 70.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Third Observation Date | 80.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Fourth to Seventh Observation Dates | Various (below Initial Underlying Level) | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Eighth Observation Date (the Final Valuation Date) | 110.00 | Closing level of Underlying at or above Initial Underlying Level; Notes are automatically called; Issuer pays the Call
Price applicable to the Final Valuation Date on the Maturity Date. |

Call Price (per Note):	$11.77
Total Return:	17.70%

In this example, the Notes are not automatically called prior to the Final Valuation Date because the Closing Level on each Observation Date preceding the Final Valuation Date is less than the Initial Underlying Level.

However, because the Closing Level of the Underlying is greater than or equal to the Initial Underlying Level on the Final Valuation Date, the Notes are automatically called on the Final Valuation Date. The Issuer will pay you on the Maturity Date a Call Price of $11.77 per Note for a total return of 17.70% on the Notes.

Example 3 — Notes Are NOT Automatically Called and the Final Underlying Level Is Above the Downside Threshold

| Date | Closing
Level | Payment
(per Note) |
| --- | --- | --- |
| First Observation Date | 90.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Second Observation Date | 60.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Third Observation Date | 55.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Fourth to Seventh Observation Dates | Various (below Initial Underlying Level) | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Eighth Observation Date (the Final Valuation Date) | 85.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called. Final Underlying Level above
Downside Threshold; Issuer repays principal on Maturity Date. |

Payment at Maturity (per Note):	$10.00
Total Return:	0.00%

Because the Closing Level of the Underlying was less than the Initial Underlying Level on each Observation Date, the Notes are not automatically called. Because the Final Underlying Level is greater than or equal to the Downside Threshold, the Issuer will pay you on the Maturity Date $10.00 per Note, which is equal to your principal amount, for a total return of 0.00% on the Notes.

Example 4 — Notes Are NOT Automatically Called and the Final Underlying Level Is Below the Downside Threshold

| Date | Closing
Level | Payment
(per Note) |
| --- | --- | --- |
| First Observation Date | 60.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Second Observation Date | 65.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Third Observation Date | 60.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Fourth to Seventh Observation Dates | Various (below Initial Underlying Level) | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called |
| Eighth Observation Date (the Final Valuation Date) | 45.00 | Closing level of Underlying below Initial Underlying Level; Notes NOT automatically called. Final Underlying Level below
Downside Threshold; Issuer will repay less than the principal amount resulting in a percentage loss on your investment equal
to the negative Underlying Return. |

Payment at Maturity (per Note):	$4.50
Total Return:	-55.00%

Because the Closing Level of the Underlying was less than the Initial Underlying Level on each Observation Date, the Notes are not automatically called. Because the Final Underlying Level is less than the Downside Threshold on the Final Valuation Date, at maturity, the Issuer will pay you a total of $4.50 per Note, representing a loss on the Notes of 55.00%, calculated as follows:

$10 × (1 + Underlying Return) = $10 × (1 + -55.00%) = $4.50

What Are the Tax Consequences of an Investment in the Notes?

You should review carefully the sections entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Forward or Derivative Contracts” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders,” in the accompanying prospectus supplement. The following discussion, when read in combination with those sections, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the Notes. The following discussion supersedes the discussion in the accompanying prospectus supplement to the extent it is inconsistent therewith.

Based on current market conditions, in the opinion of our special tax counsel, it is reasonable to treat the Notes for U.S. federal income tax purposes as prepaid forward contracts with respect to the Underlying. Assuming this treatment is respected, upon a sale or exchange of your Notes (including redemption upon an automatic call or at maturity), you should recognize capital gain or loss equal to the difference between the amount realized on the sale or exchange and your tax basis in the Notes, which should equal the amount you paid to acquire your Notes. This gain or loss should be short-term capital gain or loss unless you hold your Notes for more than a year, in which case the gain or loss should be long-term capital gain or loss, whether or not you are an initial purchaser of Notes at the original issue price. However, the IRS or a court may not respect this treatment, in which case the timing and character of any income or loss on the Notes could be materially and adversely affected. In addition, in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Notes, possibly with retroactive effect. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the Notes, including possible alternative treatments and the issues presented by this notice.

Non-U.S. Holders. Insofar as we have responsibility as a withholding agent, we do not intend to treat payments on the Notes to non-U.S. holders (as defined in the accompanying prospectus supplement) as subject to U.S. withholding tax. However, non-U.S. holders should in any event expect to be required to provide appropriate Forms W-8 or other documentation in order to establish an exemption from backup withholding, as described under the heading “—Information Reporting and Backup Withholding” in the accompanying prospectus supplement. If any withholding is required, we will not be required to pay any additional amounts with respect to amounts withheld.

Treasury regulations under Section 871(m) generally impose a withholding tax on certain “dividend equivalents” under certain “equity linked instruments.” A recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2019 that do not have a “delta of one” with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on our determination that the Notes do not have a “delta of one” within the meaning of the regulations, we expect that these regulations should not apply to the Notes with regard to non-U.S. holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the Notes. You should consult your tax advisor regarding the potential application of Section 871(m) to the Notes.

S&P 500 ® Index

The Underlying consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. For more information about the Underlying, see “Indices—The S&P U.S. Indices” in the accompanying index supplement, as supplemented by the following updated information. Beginning in June 2016 (or July 2017, in the case of IEX), U.S. common equities listed on Bats BZX, Bats BYX, Bats EDGA, Bats EDGX or IEX were added to the universe of securities that are eligible for inclusion in the Underlying and, effective March 10, 2017, the minimum unadjusted company market capitalization for potential additions to the Underlying was increased to $6.1 billion from $5.3 billion. In addition, as of July 31, 2017, the securities of companies with multiple share class structures are no longer eligible to be added to the Underlying, but securities already included in the Underlying have been grandfathered and are not affected by this change.

Historical Information

The following graph sets forth the performance of the Underlying from January 2, 2008 through April 5, 2018, based on the daily Closing Levels of the Underlying. The Closing Level of the Underlying on April 5, 2018 was 2,662.84. The dotted line represents a hypothetical Downside Threshold of 1,997.13, which is equal to 75.00% of the Closing Level of the Underlying on April 5, 2018. The actual Downside Threshold will be based on the Closing Level of the Underlying on the Trade Date.

Supplemental Plan of Distribution

We have agreed to sell to Barclays Capital Inc. and UBS Financial Services Inc., together the “Agents,” and the Agents have agreed to purchase, all of the Notes at the initial issue price less the underwriting discount indicated on the cover of this pricing supplement. UBS Financial Services Inc. may allow a concession not in excess of the underwriting discount set forth on the cover of this pricing supplement to its affiliates.

We expect that delivery of the Notes will be made against payment for the Notes on the Settlement Date indicated on the cover of this pricing supplement, which is expected to be more than two business days following the Trade Date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to two business days before delivery will be required, by virtue of the fact that the Notes will initially settle in more than two business days, to specify alternative settlement arrangements to prevent a failed settlement. See “Plan of Distribution (Conflicts of Interest)” in the prospectus supplement.

We or our affiliates have entered or will enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the Notes and the Agents and/or an affiliate may earn additional income as a result of payments pursuant to the swap, or related hedge transactions.

We have agreed to indemnify the Agents against liabilities, including certain liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Agents may be required to make relating to these liabilities as described in the prospectus and the prospectus supplement. We have agreed that UBS Financial Services Inc. may sell all or a part of the Notes that it purchases from us to its affiliates at the price that is indicated on the cover of this pricing supplement.

The Notes are not intended to be offered, sold or otherwise made available to and may not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA Retail Investor”). For these purposes, an EEA Retail Investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (“MiFID II”); (ii) a customer within the meaning of Directive 2002/92/EC, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC. Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended from time to time, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to EEA Retail Investors has been prepared and therefore offering or selling such Notes or otherwise making them available to any EEA Retail Investor may be unlawful under the PRIIPs Regulation.
