DoubleLine Capital CEO Jeffrey Gundlach has warned that the Treasury market is signaling the Federal Reserve must move beyond rhetoric to effectively combat inflation.

Gundlach pointed to divergent moves across the yield curve as evidence that investors remain skeptical of the central bank's ability to deliver on its 2% inflation target without concrete policy action.

The comments come as Federal Reserve Chair Kevin Warsh prepares to reiterate the central bank's commitment to price stability.

Recent reports indicate Warsh is expected to emphasize the Fed's unwavering stance on bringing inflation back to target, a message that has already begun to influence market expectations.

US Treasury yields climbed sharply earlier in the week as traders digested Warsh's stern warnings about persistent inflation.

The rapid adjustment in yields reflects a market recalibrating its expectations for the future path of interest rates, with investors weighing the credibility of the Fed's hawkish posture against actual policy outcomes.
