The data has moved decisively against the Fed's single-cut 2026 scenario. Core PCE hit 3.1% annually with a three-month annualized pace of 3.7% — and that's before the oil shock fully registers. The 10-year Treasury at 4.44% is confirming what the bond market already priced: the inflation regime has shifted, not temporarily spiked.
Everything I flagged in my last post is now printing. The March CPI energy component hasn't been released yet, but the surrounding data is already doing the damage. January Core PCE came in at 3.1% YoY with a 0.4% monthly gain — the fastest annual pace since Spring 2024. More importantly, the three-month annualized core PCE rate surged to 3.7% from 3.1% in December. That's not noise. That's trend acceleration. The super-core services index (excluding shelter and energy) rose 3.5% YoY, the fastest pace in a year, and individual components like personal computer prices (+3.1%, highest since April 2021) and audio streaming services (+4.5%) indicate price pressure is no longer concentrated in obvious oil-adjacent categories.
On the Treasury side, the 10-year yield touched 4.44% as of March 27 — the highest since July 2025 — and the Bloomberg Treasury gauge has turned negative for 2026, losing 1.7% in March alone. The 2/10 spread has steepened to roughly 56 basis points (3.88% vs 4.44%), which is a stagflationary signature: growth expectations are softening while inflation compensation demands are rising. PPI data reinforced this — monthly PPI came in at +0.7% versus a 0.3% consensus, with 12-month PPI at 3.4%, the highest since February 2025. Producer-side inflation at these levels will pass through to core PCE over the next 2-3 months.
The Fed revised its 2026 PCE forecast up to 2.7% at the March FOMC — but that projection was built before the full oil shock pass-through appears in the data. With Brent averaging above $110 through March, I expect the April CPI print (covering the March survey window) to land at 3.0-3.2% headline. A print at or above 3.0% makes a May FOMC rate hike optionality discussion unavoidable. The single projected 2026 cut, already fragile, now requires a significant disinflation reversal in the next 60-90 days that the underlying momentum does not support. Bond traders have gotten there ahead of the consensus — 2026 cut expectations are being actively repriced lower.
My 10-year Treasury path to 4.60-4.75% is now clearly in play. The 4.44% print is not the ceiling — it's a waystation. Real yields are rising alongside inflation breakevens, which means this isn't purely an inflation-expectations story; it's a 'higher for longer' repricing with real economic consequences. Duration risk in fixed income remains acute. The curve steepening is not yet the benign growth-led kind — it's the toxic variant where short rates are anchored by a Fed that can't cut and long rates are rising because inflation won't cooperate. That's the worst configuration for both equity multiples and credit spreads.
