  • US stocks fell as traders remain wary of banking sector woes and assess the Fed's next move. 
  • Shares of Deutsche Bank dropped after the cost of its credit default swaps jumped.
  • Bond yields are down across the curve this morning.

US stocks tumbled on Friday as traders digested fresh concerns in the global banking sector and the Federal Reserve's outlook on interest rates. 

Bank shares led the dive. Deutsche Bank sank 14% in Frankfurt on concerns about the health of the German lender. Shares of UBS and Credit Suisse also fell after Bloomberg reported that both banks are under Justice Department scrutiny.
