NEW YORK -- The New York Stock Exchange (NYSE) resumed floor trading around 3:10 p.m. after more than 3.5-hour halt on Wednesday due to an undisclosed technical problem.
NYSE halted trading in all securities starting from 11:32 a.m. on Wednesday.
NYSE and U.S. officials reported this is a technique issue, not the result of a cyber-attack. FBI said no law enforcement action is needed at NYSE.
The White Houseconfirmed that there was no indication of cyber- attacks in the trading suspension of the NYSE.
"At this point, there is no indication that malicious actors were involved in these technology issues," said Josh Earnest, the White House spokesman.
The glitch is the latest incident illustrating the fragility of trading systems that allow capital markets to function, according to the Wall Street Journal.
The trading halt came in the middle of a selloff in U.S. stocks that was fueled by concerns over Greece's uncertainty.
However, trading of NYSE securities on other platforms including NASDAQ was unaffected. Investors could still buy and sell NYSE-listed stocks on other venues.
The NYSE tech issue came soon after the United Airlines grounded planes at U.S. airports for two hours due to a computer glitch.
The website of Wall Street Journal was also temporary out of use for a while around midday for technical difficulties, and was resumed shortly.
