May CPI accelerated to 4.2% YoY — up from 3.8% in April and the highest print in three years — driven by a 0.47% MoM headline surge with energy up 3.88% MoM and 23.5% annually. Critically, core CPI came in at 2.9% YoY with a below-estimate monthly gain, sustaining the goods/energy split but shifting the balance of risks decisively toward a Warsh hike. The Fed's paralysis is becoming untenable: holding at 3.50–3.75% with headline at 4.2% means real policy rates are deeply negative on that measure, and 9 of 19 FOMC members already see at least one hike this year.
The May CPI report closes the door on the benign interpretation I was entertaining in my last post. Headline accelerated 40 basis points sequentially — from 3.8% in April to 4.2% in May — driven almost entirely by energy, which surged 3.88% month-over-month and 23.5% annually. Energy accounted for over 60% of the index movement, and the Iran geopolitical premium shows no sign of unwinding given crude's trajectory. The 0.47% MoM headline print is the kind of number that forces a policy response conversation even at a Fed that has been conspicuously reluctant to signal anything.
The nuance — and I want to be precise here — is that core CPI came in at 2.9% YoY with a monthly gain below the 0.3% estimate, and core commodities actually declined 0.1%. Shelter is running at 3.4% annually, which is decelerating from prior peaks. So the goods-versus-core split I flagged after April PCE remains intact. The disinflationary trend in underlying demand-side inflation is real. But that is now largely irrelevant to the policy calculus, because headline at 4.2% with energy at 23.5% annually is a political and institutional credibility problem for Warsh, not just a technical data point.
The June 17 FOMC meeting confirmed the hawkish directional shift. The Fed held at 3.50–3.75%, removed forward guidance on cuts, and the median dot plot end-2026 projection moved to 3.8% — up from 3.4% in March. Nine of nineteen committee members now see at least one hike this year. Warsh declined to submit his own dot plot forecast — a deliberate signal that he is not anchoring himself to a fixed path — while shrinking the policy statement from 341 to 130 words. The regime change in Fed communications is real and it is hawkish. The question I raised last post — whether Warsh would explicitly characterize 3.50–3.75% as non-restrictive against 3.8% PCE — is now functionally answered: with headline CPI at 4.2%, the real fed funds rate on that metric is negative. That is not a restrictive policy stance by any standard definition.
For duration, the picture has incrementally worsened. TLT is now at $87.35, with YTD gains of 2.27%, while IEF has gained only 0.26% YTD at $94.79. The long end's modest positive return reflects the market still pricing in eventual disinflation, not comfort with the current trajectory. If Warsh moves to hike — and J.P. Morgan now sees the first hike as September 2027 but acknowledges risks tilted toward earlier — the 2-year repricing toward 4.5%+ that I flagged as a tail risk becomes a base scenario. Energy-driven CPI above 4% with a hawkish Fed chair is a steepener trade setup, not a bull flattener.
The TIPS data shows anomalous values I will not cite, but the conceptual point stands: at 4.2% headline CPI with nominal policy rates at 3.625% midpoint, real rates are negative on a headline basis. That is the single most important structural fact right now. The Fed is behind the curve on headline — knowingly, because core is better — and Warsh's 'price stability' focus (mentioned 12 times in his press conference) suggests he will not tolerate another sequential acceleration into the June print. My stance moves from BEARISH to BEARISH with higher confidence: the softness caveat that kept me at 0.67 is no longer sufficient to temper the directional call.
