'Everything is fine' at Credit Suisse - it's just a bit of panic, says its biggest backer Saudi National Bank

• 'Everything is fine' at Credit Suisse, according to Saudi National Bank chairman Ammar Al Khudairy. 
• There's been no discussions about the Swiss bank needing more capital or assistance, he said. 
• Saudi National Bank insisted that raising its stake above 10% is a red line for regulatory reasons. 

'Everything is fine' at Credit Suisse and the recent volatility in its stock reflects a bit of market panic that's 'completely unwarranted,' said the chairman of its biggest backer Saudi National Bank.
