• Credit Suisse will receive liquidity if needed, a Swiss regulator and the country's central bank said late Wednesday. 
• Credit Suisse "meets the capital and liquidity requirements imposed on systemically important banks," the authorities said. 
• Credit Suisse shares crashed on Wednesday after its largest shareholder said no more financial backing will be granted. 

Credit Suisse will be issued liquidity if the lender needs it, a Swiss regulator and the country's central bank said late Wednesday, offering some measure of reassurance during market turmoil surrounding the company.
