Citadel Securities Warns: Rising Risk of Fed Resuming Rate Hikes in September
Claire Weston
Citadel Securities macro strategist Frank Flight warns the Fed may restart rate hikes as early as September — far more hawkish than the roughly one-third probability currently priced into swaps, signaling a rate path tougher than most expect.
Where is the inflation pressure coming from?
Oil prices pulled back after a provisional U.S.-Iran peace deal, but Flight argues inflation embedded itself in the economic structure during the conflict and will not retreat with crude.
He identifies four forces pushing prices higher at once: loose financial conditions, persistent supply-chain disruptions, a re-accelerating labor market, and surging AI investment.
This means → inflation is not a single shock but multiple pipes leaking simultaneously — plugging one (oil) leaves the others still building pressure.
What is the labor market signaling?
Wage growth is accelerating most visibly in cyclical industries — manufacturing, construction, and other sectors that move with the business cycle.
Within CPI, a growing number of sub-categories are running above 3% annualized.
In plain terms = price increases are no longer confined to a few items; "inflation" is spreading across more goods and services — the signal the Fed dreads most.
What will new Chair Warsh do?
Flight expects new Fed Chair Kevin Warsh to strike a hawkish tone at Wednesday's first policy meeting under his leadership.
He sees risk accumulating toward a path of consecutive hikes in September, December, and March 2027.
Flight writes: "The evidence argues for a decisively hawkish pivot — we believe Warsh will choose to defend inflation-fighting credibility rather than accommodate the market's dovish expectations."
How will the dot plot and inflation forecasts shift?
Flight expects at least five officials to mark a hike on the dot plot — the Fed's chart where each official plots their projected rate path.
He also forecasts an upward revision of the 2026 core-inflation projection above 3% and a modest cut to the unemployment forecast.
This means → if the official narrative shifts from "patient waiting" to "inflation is stickier than we thought," markets will be forced to reprice the entire rate curve.
How much more hawkish is Citadel than consensus?
Rate-swap markets currently imply only roughly a one-third probability of a September hike; Citadel Securities believes this severely underestimates the risk.
Using a Taylor Rule framework — a standard formula deriving "optimal" rates from inflation and the output gap — Flight calculates the best policy path this year is roughly 75 basis points of tightening.
The market baseline is merely "remove any easing bias and no cuts this year"; Citadel's call is that the speed and scale of the pivot may far exceed what markets are positioned for.
This reflects a widening split inside Wall Street over the inflation path — if Citadel is right, current bond and rate-derivative pricing is too soft.
