Euronext has joined the rush to slash exchange fees by teaming up with its clearing house LCH.Clearnet to cut equity trading costs on its four stock markets. It also unveiled plans to increase pricing transparency by separating for the first time the charges it levies on its customers.

Euronext said in a joint statement with LCH.Clearnet's Paris-based arm that the fee cuts on clearing equity trades, the process of verifying that buyer has sufficient funds to execute a transaction, would result in an overall average cost reduction of 15% for its customers.
