UBS Group AG agreed to buy Credit Suisse Group in a historic, government-brokered deal aimed at containing a crisis of confidence that had started to spread across global financial markets.

Saudi National Bank is nursing major losses in the wake of Credit Suisse's failure after a deal was reached for UBS to buy the embattled Swiss lender for $3.2 billion.

Saudi National Bank -- Credit Suisse's largest shareholder -- confirmed to CNBC Monday that it had suffered a loss of around 80% on its investment.

The Riyadh-based bank holds a roughly 10% stake in Credit Suisse, having invested 1.4 billion Swiss francs ($1.5 billion) in the Swiss lender in November of last year, at 3.82 Swiss francs per share.

Under the terms of the rescue deal, UBS is paying Credit Suisse shareholders 0.76 Swiss francs per share

The significant discount comes as regulators try to shore up the global banking system. The scramble for a rescue follows a tumultuous few weeks which saw the collapses of U.S.-based Silicon Valley Bank and First Republic bank as well as major stock price downturns across the banking sector internationally.

Shares of UBS, Switzerland's largest bank, traded down 11% at 8:55 a.m., while Europe's banking sector was around 2.8% lower.
