Bloomberg’s financial data service is back online after a system outage on Wednesday morning left traders unable to access live pricing data across global markets.
The disruption began shortly after 9am, cutting off real-time feeds used by banks, asset managers and brokers worldwide, though its internal messaging system, IB, remained operational.
The blackout prompted the UK Debt Management Office to extend the auction window for a four-year gilt sale to 11.30am, citing “ongoing market-wide Bloomberg system issues”.
The cause of the outage has not been disclosed.
Bloomberg terminals, which cost around $28,000 a year per user, are a central tool in financial markets, offering pricing, analytics, and trading capabilities across asset classes.
The company acknowledged the issue on its customer helpdesk, saying engineers were working to identify and resolve the fault.
While Bloomberg has not yet commented publicly, the platform is now fully functioning again.
