The Swiss authorities are considering the possibility of full or partial nationalization of Credit Suisse if the deal with UBS is not closed.

Switzerland is considering a full acquisition of the bank or retaining a significant stake in the capital if the takeover of UBS fails due to the complexity of the transaction and the short timeframe set for its conclusion, Bloomberg reports.

UBS completes its purchase of Credit Suisse with an offer of up to $1,000 million (930 million euros) as the country prepares a change in legislation to speed up the deal until Monday, the Financial Times reported on Sunday.

The deal could go through as early as this Sunday evening at CHF0.25 per share, well below Credit Suisse’s closing price of CHF1.86 on Friday.

However, Credit Suisse, which closed on Friday with a market value of around 7.4 billion francs ($8 billion), said the offer is too low and will hurt shareholders and employees who have shelved shares, Bloomberg reported.

The situation is uncertain and could change as financial authorities try to finalize a solution for the bank before the opening of Asian markets, which in Europe is already late in the evening, Bloomberg explained.

The acquisition of UBS comes with many complexities. The financial institution asks the government to bear certain legal costs and possible future losses.

The Swiss finance ministry declined to comment.
