UBS Group AG has offered to buy Credit Suisse for up to $US1 billion ($1.5 billion), with the Swiss government planning to change the country’s laws to bypass a shareholder vote on the transaction, the Financial Times reports.

Credit Suisse and UBS declined to comment and the Swiss government did not immediately respond to a request for comment on Sunday.

However, Bloomberg News, citing people with knowledge of the matter, said Credit Suisse was resisting the offer, believing it to be too low and that it would hurt shareholders and employees who have deferred stock.

Authorities have been racing to rescue the 167-year-old bank, among the world’s largest wealth managers, before financial markets reopen on Monday.

As one of 30 global systemically important banks, Credit Suisse’s failure would ripple throughout the financial system.

The Financial Times reported that the all-share deal was set to be signed as early as Sunday.

Citing people familiar with the matter, it said an offer was made on Sunday morning at 0.25 Swiss francs per Credit Suisse share, well below Friday’s closing price of 1.86 Swiss francs and all but wiping out the bank’s existing shareholders.

UBS has also insisted on a “material adverse change” that voids the deal in the event its credit default spreads jump by 100 basis points or more, the report added.

However, it noted that the situation was fast-moving and there was no guarantee that terms will remain the same or that a deal would be reached.

A person with knowledge of the talks earlier told Reuters that UBS was seeking $US6 billion from the Swiss government as part of a possible purchase of its rival.

The guarantees UBS is seeking would cover the cost of winding down parts of Credit Suisse and potential litigation charges, two people told Reuters.

One source previously cautioned the talks were encountering significant obstacles and 10,000 jobs may have to be cut if the two banks combine.

The Swiss Bank Employees Association on Sunday called for the immediate creation of a task force to deal with the risk to jobs.

The frenzied weekend negotiations over the future of Credit Suisse follow a brutal week for banking stocks and efforts in Europe and the United States to shore up the sector following the collapse of US lenders Silicon Valley Bank and Signature Bank.

US President Joe Biden’s administration moved to backstop consumer deposits while the Swiss central bank lent billions to Credit Suisse to stabilise its shaky balance sheet.

UBS was under pressure from the Swiss authorities to take over its local rival to get the crisis under control, two people with knowledge of the matter said.

The plan could result in Credit Suisse’s Swiss business being spun off, while Bloomberg reported that the takeover talks were throwing into doubt plans to hive off its investment bank under the First Boston brand.

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 the United Kingdom as a key market.

Credit Suisse shares lost a quarter of their value in the last week.

The bank was forced to tap $US54 billion in central bank funding as it tries to recover from a string of scandals that have undermined the confidence of investors and clients.
