The New York Stock Exchange halted all trading Wednesday morning in an unprecedented move, saying it was experiencing an “internal technical issue.”
Although the exchange denied that it had fallen victim to a “cyber breach,” similar shutdowns by the Wall Street Journal and United Airlines on Wednesday morning have sparked concern that the organizations may have been hacked.
The NYSE has been shut down since 11:32 a.m. ET.
President Obama has been informed of the NYSE’s technical problem by White House counterterrorism and homeland security adviser Lisa Monaco and chief of staff Denis McDonough, according to White House spokesman Josh Earnest.
Monaco told the president there is no indication that the shutdown is part of a cyberattack, the Associated Press reports.
NYSE President Thomas Farley tells CNBC he plans to reopen the market by 2:45 or 3 p.m. ET. The floor is “not quite ready to open yet,” he adds.
The issues have not affected other exchanges like the NYSE Arca and NYSE Amex/Arca Options.
Earlier on Wednesday, United Airlines grounded all of its U.S. flights, citing a “network connectivity issue,” according to CNN Money. The Wall Street Journal‘s website also went down due to “technical difficulties” at the same time the NYSE suspended trading.
