Sharecast - The pan-European Stoxx 600 index was down 0.11% at 1130 GMT after Powell told lawmakers in Washington that recent strong economic data had bolstered the case for more aggressive action to tame inflation.
"Despite the Fed’s hawkish stream of hikes over the past year, core inflation remains persistently higher at 5.6% in January and the US economy is also proving to be stronger than expected," said Interactive Investor head of investment Victoria Scholar.
"US stock markets sold off yesterday amid the prospect of further tightening while the dollar and treasury yields rose. Focus will be on Friday’s US non-farm payrolls report in which good news could be bad news; a strong headline jobs figure and wage growth could pave the way for a less accommodative 50 basis point move from the Fed in March."
"Markets are currently pricing in around a 50-50 split between chances of a 25-basis point move and a 50-basis point move at the Fed’s next rate setting meeting. Futures contracts suggest the policy rate will peak around 5.25%-5.5% in June but some are expecting the Fed Funds rate to push beyond that.”
