Powell still shows a hawkish attitude in operating monetary policy, which is not new. Last night's statement made the market worry that the next interest rate increase on March 23 will be large. However, we still have to look at the CPI on March 14.
Please note that Powell is still hawkish. From a basic perspective, if Powell is too hawkish and pushes the Fed fund rate up, a short time later other economies will follow suit.
