Major European stock markets all opened lower on Monday, amid scepticism at the hurried conclusion of the acquisition of Credit Suisse by fellow Swiss bank UBS, which has not erased fears about the stability of the banking sector.
Shares in UBS fell 8.8% at the opening of the Zurich Stock Exchange after the deal to buy Credit Suisse, its traditional rival, which had been at risk of bankruptcy due to an irremediable crisis of confidence.
Switzerland’s government offered substantial guarantees for the deal to proceed – including using certain emergency instruments – on the grounds that the collapse of Credit Suisse could generate a financial crisis not only domestically but globally.
However, investors on Monday morning appeared dissatisfied with the deal, whereby UBS agreed to buy Credit Suisse for the €3bn, a price it will pay in shares only and valuing the absorbed entity’s shares at 40% of their value at the close of Friday’s trading.
On a day of widespread share falls in Europe, investors will analyse the purchase of Credit Suisse by UBS, and the coordinated action of the main central banks to provide liquidity to the system.
