UBS sealed a deal to buy rival Swiss bank Credit Suisse in an effort to avoid further market-shaking turmoil in global banking, Swiss authorities said on Sunday.
The Swiss central bank will supply substantial liquidity to the merged bank, it said at a news conference in the Swiss capital, Bern. It said the deal marked a solution to secure financial stability and protect the Swiss economy in an exceptional situation.
A deal value was not immediately clear. A report in the Financial Times earlier put it at more than $2 billion.
Officials have been racing to rescue the 167-year-old bank, among the world's largest wealth managers, after a brutal week saw the second- and third-largest US bank failures in history.

Swiss authorities are examining imposing losses on Credit Suisse bondholders as part of a rescue of the bank, two sources with knowledge of the matter said on Sunday.
However, European regulators are apprehensive about such a move for fear that it could hit investor confidence elsewhere in Europe's financial sector, the sources said, speaking on the condition of anonymity.
US authorities are working with their Swiss counterparts to help broker a deal, Bloomberg reported, while Sky News said the Bank of England has indicated to international counterparts and to UBS that it would back the proposed takeover of Credit Suisse, which counts Britain as a key market.
