US Yield Curve Steepens as Markets Question Fed Resolve

The US Treasury yield curve steepened sharply after the Federal Reserve's decision to leave interest rates unchanged, raising concerns about the central bank's credibility and willingness to take action against inflation.

Analysts say the combination of falling short-term Treasury yields and rising long-term yields suggests investors are becoming increasingly skeptical that the Fed will raise interest rates again, despite Chair Kevin Warsh's insistence that policymakers 'will not hesitate to act' if inflationary pressures persist.

Zachary Griffiths, Head of Investment Grade and Macro Strategy at CreditSights, described the move as a 'twist steepener', calling it an 'unhealthy response' to the Fed's policy decision. The trend continued during Thursday's session, with the gap between short- and long-term Treasury yields widening further.

Markets are questioning the Fed's resolve in fighting inflation, with some analysts believing that financial conditions have already tightened significantly without additional policy action.
