Trading on Euronext NV’s European exchanges was halted for more than an hour Tuesday because of a technical malfunction, preventing transactions in companies ranging from Royal Dutch Shell Plc to Sanofi.

Citing a problem with market data, Euronext paused trading at 12:15 p.m. Paris time, according to a notice on its website. Trades for stocks and bonds resumed at 1:10 p.m., and for other products including exchange-traded funds at 1:15 p.m.

Technology errors may jeopardize credit ratings for exchanges, Standard & Poor’s said in September. The hour-long closure at Euronext follows a three-hour pause on Aug. 22 for thousands of U.S. stocks, including Apple Inc. and Microsoft Corp., because of an error at Nasdaq OMX Group Inc. In response, U.S. regulators demanded exchanges make their systems more reliable.

IntercontinentalExchange Group Inc. is in the process of spinning off Euronext, which runs markets in Paris, Amsterdam, Brussels and Lisbon. Atlanta-based ICE bought it in November along with the Liffe derivatives market and New York Stock Exchange.

ICE suspended some European futures trading during the malfunction.
