At roughly $1.7 trillion, the combined assets of the new entity amount to double the size of Switzerland’s annual economic output. By deposits and loans to Swiss customers, UBS will now be bigger than the next two local banks combined.

Taxpayers, meanwhile, are now on the hook for up to 9 billions Swiss francs ($9.8 billion) of future potential losses at UBS arising from certain Credit Suisse assets, provided those losses exceed 5 billion francs ($5.4 billion). The state has also explicitly guaranteed a 100 billion Swiss franc ($109 billion) lifeline to UBS, should it need it, although that would be repayable.
