The Federal Reserve kept its benchmark interest rate unchanged in the 3.50%-3.75% range, a widely expected decision that nevertheless revealed deep divisions within the central bank. Three of the 12 members of the Federal Open Market Committee dissented, arguing for a different course of action. In the aftermath, long-term Treasury yields jumped as investors questioned whether Fed Chairman Warsh will act forcefully enough to curb inflation. Warsh, in a statement following the decision, vowed not to 'waver' on inflation, seeking to reassure markets that the Fed remains committed to price stability. The rate hold marks a pause after a series of hikes, as policymakers debate the pace of further tightening. Analysts note that the dissenters' stance suggests growing internal pressure for more aggressive action. The jump in bond yields reflects skepticism among investors about the Fed's resolve, despite Warsh's pledge. The central bank's next meeting is scheduled for later this year, and all eyes will be on whether the Fed can balance its inflation fight with concerns about economic growth.
