Bloomberg Terminal Outage Halts Trading, Delays UK Bond Auction

Bloomberg's data terminals went down Wednesday morning, halting trading activity worldwide. The outage lasted nearly 90 minutes and hit just as markets opened.
Traders relying on Bloomberg’s system couldn’t access live prices. Without real-time data, many were forced to pause operations.
“We were told to stop trading,” said one London-based fund manager. “This level of failure is rare,” he added.
The glitch caused the UK Debt Management Office to delay a government bond auction. Officials extended bidding by 90 minutes due to the system failure.
Live market pricing is critical for auction participants. Without it, fair bidding becomes impossible.
Bloomberg terminals have powered the global financial system for decades. Founded by Michael Bloomberg, the black-and-orange screens now serve as key tools for banks, funds, and traders.
The platform doesn’t just offer pricing—it also enables encrypted communication between market participants. Its sudden collapse rippled across desks in London, New York, and beyond.
“There’s no way to trade blind,” said one trader. “Would you bet on a match if you didn’t know the score?”
Other services like LSEG Workspace and FactSet offer data, but Bloomberg remains the industry’s benchmark. Wednesday’s outage showed how much the financial world still depends on a single source.
