Many users were unable to access live data, forcing some traders to halt activity. The system is used by banks, asset managers, and other market participants around the world.
In a statement, Bloomberg said: “Our systems are returning to normal operations and Terminal functionality has been restored following a service disruption earlier today.”
Pricing Data Loss Disrupts Sovereign Sales
The problem also affected UK and EU government bond auctions. The UK Debt Management Office extended the bidding window for a gilts sale by 90 minutes. The European Commission also delayed the deadline for an EU bond auction by one hour.
Two large investment banks confirmed the disruption to their trading desks. One source said that traders could not access pricing data during the UK gilts auction and were unable to take client orders.

Traders Use Messaging Amid Bloomberg Disruption
Despite the pricing data failure, Bloomberg’s instant messaging service, known as IB, continued to function. This allowed some traders to communicate and agree on deals to be settled later.
Bloomberg first acknowledged the issue in a message. It stated: “We’re currently experiencing a global terminal issue, and our engineering team is actively working to identify and resolve the problem.”
Bloomberg terminals are widely used across the financial services industry. Alternatives such as LSEG’s Workspace and FactSet exist, but Bloomberg holds a dominant market position. The company’s service costs around $28,000 per year per user.
