UBS Group AG is aiming to avoid using a $10 billion backstop for Credit Suisse amid a backlash, the Financial Times reported on Sunday.
UBS executives are hoping to announce that the bank will not call on the government backstop when it publishes its second-quarter results on Aug 31, the report added.
UBS declined to comment while Credit Suisse did not immediately respond to Reuters' request for comment.
In June, UBS reached an agreement with the Swiss government under which the government will guarantee up to ₣9 billion ($9.98 billion) of losses UBS may incur from the sale of its rival's assets beyond 5 billion francs the lender is due to cover itself.
The government's and UBS' priority was to "minimise potential losses and risks so that recourse to the federal guarantee is avoided to the greatest extent possible," the government said.
Valuations of the losses are expected to be made available during the third quarter of 2023, the government said.
Chief Executive Sergio Ermotti has said UBS' leadership would do everything possible to prevent Swiss taxpayers from bearing the costs of the take over.
