Chair Walsh reiterated his determination to fight inflation but did not clarify the path of future actions, leaving the market speculating about the direction of policy. IG analysts pointed out that if the Federal Reserve is unwilling to commit to further tightening, it may shake the credibility of its anchoring long-term inflation expectations.3.
