NYSE says trading halted due to ‘technical issue,’ not breach

Trading on the New York Stock Exchange (NYSE) came to a halt Wednesday.

“We're currently experiencing a technical issue that we're working to resolve as quickly as possible,” according to an NYSE statement emailed to “We will be providing further updates as soon as we can, and are doing our utmost to produce a swift resolution, communicate thoroughly and transparently, and ensure a timely and orderly market re-open.”

Following the statement, three tweets were posted to the NYSE Twitter account: “The issue we are experiencing is an internal technical issue and is not the result of a cyber breach," one said. "We chose to suspend trading on NYSE to avoid problems arising from our technical issue," said another. "NYSE-listed securities continue to trade unaffected on other market centers," the third tweet noted.

Trading came to a halt in New York a little after 11:30 a.m., the AP reported, adding that shares continue to be traded on other exchanges such as Nasdaq.

According to a NYSE market status history website, connectivity issues – reported earlier in the day and seemingly resolved prior to 9:30 a.m. – may have impacted certain orders.
