The Federal Reserve issued a detailed and scathing assessment on Friday of its failure to identify problems and push for fixes at Silicon Valley Bank before the U.S. lender's collapse, and promised tougher supervision and stricter rules for banks.

Some financial industry executives and investors were growing increasingly concerned on Saturday that the collapse of Silicon Valley Bank could have a domino effect on other U.S. regional banks if regulators did not find a buyer over the weekend to protect uninsured deposits.

U.S. consumer prices rose solidly in December, with the annual increase in inflation the largest in nearly four decades, which could bolster expectations that the Federal Reserve will start raising interest rates as early as March.
