More than ten thousand private messages sent between users of Bloomberg’s financial terminals have leaked online, undermining the company’s attempts to restore faith in its ability to keep client data confidential as it scrambles to allay clients’ privacy concerns.
Two long lists showing confidential Bloomberg messages between traders at dozens of the world’s largest banks and their clients have been online for several years, the Financial Times has learnt.
The documents from one particular day in 2009 and also from 2010, contain messages sent in by clients so Bloomberg could extract price data on bonds, credit default swaps and other financial products from traders’ messages.
