PARIS, Oct 13 (Reuters) - Trading on NYSE Euronext's European cash markets returned to normal in time for the market close on Wednesday after a 35-minute shutdown caused by technical problems.
Although Euronext had mulled a possible delay of closing auction times, markets closed at the normal time of 1535 GMT.
The disruption affected all Euronext European markets, including Paris, Amsterdam, Brussels and Lisbon, officials said.
Euronext first halted European trading at around 1445 GMT and markets only gradually began to return to normal around 1520 GMT, the bourse operator's website said.
During the shutdown no trades could be processed, Paris-based representatives of Euronext's markets surveillance said.
"There is no access to the market, members cannot input orders," one representative said.
At market close the Paris benchmark CAC-40 index was up 2.1 percent, at 3,828.34 points, while the Brussels BEL20 index was up 1.9 percent, at 2,670.38 points. The STOXX Europe 50 blue-chip index was up 1.6 percent.
