Credit Suisse has secured a $54 billion loan from the Swiss National Bank in a bid to shore up investor confidence and liquidity following a significant drop in its share price on Wednesday.
The bank plans to use the additional liquidity to create a "simpler and more focused bank".
The announcement came after a crisis of confidence in the global banking system led to fears of a broader financial crisis.
Credit Suisse became the first major global bank to be given an emergency lifeline since the 2008 financial crisis as it secured a $54 billion loan from the Swiss National Bank to shore up investor confidence and liquidity.
Credit Suisse CEO Tidjane Thiam said the bank had taken "decisive action" to strengthen the bank "as we continue our strategic transformation to deliver value to our clients".
However, JPMorgan analysts claimed that "status quo was no longer an option," and that a takeover of Credit Suisse was the most likely outcome.
The move came after a plunge in shares of Credit Suisse triggered fears of a full-blown banking crisis, though Swiss authorities insisted the bank was sound and met "the capital and liquidity requirements imposed on systemically important banks".
