Investors assessing the Federal Reserve's decision to keep interest rates steady this week may be suffering from a false sense of security.

According to a global macro strategy report authored by Frank Flight at Citadel Securities, the market is severely under-indexing a looming hawkish pivot.

The firm warns that temporary supply shocks are structurally altering the U.S. economy, rendering the June pause a brief intermission before "second-round effects" inevitably forcing a September rate hike.

The Myth Of The June Pause While the FOMC maintained the target range for the federal funds rate at 3.5% to 3.75% during Chairman Kevin Warsh's first meeting, Citadel's analysis suggests underlying economic indicators tell a far more aggressive story.

The report details a growing risk that the U.S. inflation process is shifting toward a "hysteretic equilibrium," meaning that price pressures will durably persist even as initial energy shocks fade.
