February CPI printed 2.4% YoY — flat with January and superficially benign — but this number is a rearview mirror reading that predates the February 28 Persian Gulf disruption that sent Brent to $119.50. The Fed held rates at 3.5%-3.75% with one dissenter favoring a cut, confirming the committee is not moving anywhere fast. The real inflation story begins with March data on April 10.
February's headline CPI at 2.4% YoY looks stable on the surface — same as January, shelter pushing up, nothing dramatically different. But this print is essentially pre-shock data. The U.S.-Israel strikes on Iran on February 28 — the final day of the measurement month — had essentially zero impact on February's CPI composition. Brent crude spiked from ~$70 to $119.50, gasoline jumped 19% to $3.50/gallon, and the Persian Gulf chokepoint disruption is being described as historically severe. None of that is in this number. The February CPI is a calm before a storm that has already arrived.
The Fed's decision to hold at 3.5%-3.75% is unsurprising but telling. With one dissenter favoring a cut, there's residual dovish pressure inside the committee even as the external environment deteriorates sharply. The FOMC statement acknowledges 'elevated inflation' and 'geopolitical uncertainties' — language that reads as a euphemism for 'we are watching a supply shock unfold and have no clean policy response.' The balance sheet posture has also shifted: the Fed has discontinued runoff and initiated reserve management purchases, which introduces a latent easing bias into the liquidity backdrop even as rates stay elevated. That combination — rates held high, balance sheet expanding — is not historically a stable equilibrium.
J.P. Morgan's forecast of 3.2% U.S. core CPI for 2026 now looks conservative rather than hawkish given the energy shock layered on top of already-sticky services inflation. My prior read had core PCE at 3.1% and accelerating; the oil passthrough into core via transportation, airfares, and goods distribution channels will apply additional pressure beginning in the March-April CPI prints. Cleveland Fed daily nowcasts will be the actionable leading indicator here — if they push above 3.2% core PCE equivalents in April, the 2026 cut narrative is not just dead, it's buried.
The 5-year TIPS breakeven and 10-year nominal yield dynamics remain the key transmission mechanism to watch. If the energy shock drives inflation breakevens toward and through 2.90% on a sustained basis, that's not a cyclical blip — it's a structural repricing of the Fed's inflation-fighting credibility. Real yields, which have already been elevated, face the uncomfortable scenario of nominal yields rising faster than breakevens can absorb, compressing risk appetite across duration-sensitive assets. Long-duration nominal Treasuries remain structurally vulnerable. Equities with high earnings multiples reliant on discount rate assumptions built at sub-3.5% terminal rates face analogous pressure.
The April 10 CPI release is the next hard data point that matters. A March print that captures even partial oil passthrough — and it will, given the gasoline move — should push headline CPI well above 3.0% YoY, potentially toward 3.3-3.5% depending on shelter persistence. That would be the largest single-month acceleration in the inflation trajectory since 2022, and it would arrive while the Fed is already holding rates with no clear easing path. My base case remains BEARISH on duration, BEARISH on rate-cut timing, and increasingly concerned about stagflationary dynamics where growth slows (unemployment edging up per the FOMC statement) while inflation re-accelerates via a commodity shock the Fed cannot address with its existing tools.
