SEC, FBI & Rival Exchanges Respond to NYSE Shutdown

Updated 3:45pm ET: The New York Stock Exchange (NYSE:ICE) resumed trading around 3:10pm ET after trading was halted on all shares mid-morning Wednesday. The NYSE cited an internal technical issue as the cause. In a tweet, the exchange stressed the situation is not a result of cyber breach.

Securities and Exchange Commission Chair Mary Jo White responded with a statement posted on the agency's website.

"We are in contact with NYSE and are closely monitoring the situation and trading in NYSE-listed stocks. While NYSE is working to resolve the situation, NYSE and NYSE MKT stocks continue to trade normally through other trading venues."

When a situation like this occurs, trading is routed to any of the other multiple U.S. stock venues. Exchanges including chief rival Nasdaq OMX (NASDAQ:NDAQ) and the CME Group  (NYSE:CME), the derivatives giant, are all operating without incident.

SIFMA, the Securities Industry and Financial Markets Association, which represents the industry has been re-tweeting the NYSE tweets. As of publication the group has not responded to request for comment from

The FBI is also monitoring the situation, with an FBI official telling Fox News that the Bureau has offered its assistance concerning the NYSE situation, but at this time this does not appear to be nefarious.

In Washington, the White House and the Treasury Department are monitoring the situation at the New York Stock Exchange.

InternationalContinental Exchange (NYSE:ICE) which purchased NYSE Euronext for $11 billion in November of 2013 has not commented independently on the situation.
