Swiss bank UBS is close to buying back billions of dollars in bond debt whose value collapsed during the global financial crisis, a source familiar with the situation has said.
The report followed an announcement late last night from Citigroup and Merrill Lynch that they would buy back almost $20 billion such debt between them.
"The rumours that they are close to a settlement are not unfounded," the source said.
"Both Citigroup and Merrill Lynch announced retail programmes. The one that UBS is rumoured to announce will also cover institutional clients."
The size of the buy-back would be roughly $19.4 billion, the source said.
The move is likely to force UBS, Europe's biggest casualty of the markets turmoil, to make further writedowns on the value of its assets beyond the $37 billion so far.
UBS has been locked in a dispute with New York State, which accused the Swiss bank of steering broker clients into so-called auction-rate securities that became impossible to sell when the credit market froze. UBS now has a bill for the bonds at face value even though they are worth less.
UBS declined to comment beyond saying that it was "consistently working with regulators towards a comprehensive solution for all auction-rate securities investors".
The report came as Europe's biggest computer chip maker STMicroelectronics took legal action against Credit Suisse for investing its money into auction-rate securities without asking .
Auction rate securities are like regular bonds only the interest rate is set periodically at an auction. If no bidders turn up for the auctions - held every 7, 28 or 35 days - the market freezes. Many big banks which sold investors the bonds had played down the risk of such a freeze.
