EURONEXT ANNOUNCES VOLUMES FOR SEPTEMBER 2016

Amsterdam, Brussels, Lisbon, London and Paris – 5 October 2016 – Euronext, the leading pan-European exchange in the Eurozone, today announced trading volumes for September 2016.

• The September 2016 average daily transaction value on the Euronext cash order book stood at €6,363 million (-21.2% compared to September 2015 and +31.4% compared to August 2016). Activity on ETFs followed the same trend with an average daily transaction value of €437 million, down by -28.8% compared to September 2015. However, our ETF offering continued its expansion with 4 new listings this month. In total, 791 ETFs are listed on Euronext at the end of September 2016 which represents a net increase of 101 ETFs compared to end of September 2015.
• The average daily volume on equity index derivatives was down at 210,074 contracts in September 2016 (-15.0% compared to September 2015 and +32% compared to August 2016), and the average daily volume on individual equity derivatives decreased to 194,196 contracts (-16.7% compared to September 2015 and +18% compared to August 2016).
• In September 2016, the average daily volume on commodities derivatives decreased by -36.7% compared to September 2015, with an average daily volume of 37,128 contracts. A very poor 2016 grain harvest in France is affecting all grains trade sectors.
• On a year-to-date basis, the overall average daily volume on Euronext derivatives stands at 490,474 contracts (-10.7% compared to end of September 2015) and the open interest remained almost flat at 14,896,542 contracts (+0.4% compared to end of September 2015).
• In September 2016, Euronext had three new listings, including Takeaway.com on Euronext Amsterdam as well as two SMEs that altogether raised €331 million. In addition, €9.7 billion were raised on Euronext in corporate bonds and €1.6 billion of follow-on equity, making a total of €11.6bn raised by corporates on Euronext markets over the month.
