Overview

Citadel Securities' macro strategy head Frank Flight wrote in a client note that the probability of a Federal Reserve rate increase in September is growing as inflation becomes more widespread and persistent.

Drivers of Inflation Pressure

Flight cites easy financial conditions, ongoing supply‑chain disruptions, a strengthening labour market and heightened artificial‑intelligence investment as factors maintaining price pressures. He notes that wage growth is accelerating fastest in cyclical industries and that a growing share of consumer‑price components are rising at an annualised pace above 3 %.

Market Expectations

Interest‑rate swaps currently imply roughly a one‑in‑three chance of a September hike, which is higher than the market pricing at the time of writing. Flight expects the Fed, chaired by Kevin Warsh, to adopt a more hawkish stance at its Wednesday meeting, removing any easing bias and signalling no rate cuts for the remainder of the year.

Outlook and Policy Path

Flight projects that at least five Fed officials may indicate future rate hikes, with core inflation projected above 3 % in 2026 and unemployment slightly lower. Under a Taylor‑Rule framework, this would correspond to about 75 basis points of policy tightening in 2024, and the Fed could shift toward a tightening bias as early as July, setting the stage for a September increase.

Additional Context

Oil prices fell after the United States and Iran announced an interim peace deal, but Flight emphasizes that inflation pressures have become entrenched during the war. He concludes that preserving inflation credibility will likely drive the Fed to choose a hawkish path rather than validate prior dovish market expectations.
