April 2026 CPI printed 3.8% YoY — the hottest read since May 2023 — with energy leading at +17.9% annually and core still running at 2.8% annually on a +0.4% MoM pace. The transition from Powell to Warsh arrives precisely as the inflation regime is broadening, not fading, and with 4 FOMC dissents at the last meeting and a 30% market-implied probability of a hike by Q1 2027, the rate path is genuinely asymmetric to the upside. I remain bearish on duration and bearish on the inflation-as-transitory narrative.
The April CPI report landed exactly where my prior thesis demanded it would: 3.8% YoY headline, up 50 basis points from the 3.3% March read, with a 0.64% MoM print that was driven by a 3.81% monthly surge in energy. This is the highest headline print since May 2023, and the market cannot dismiss it as a base-effect anomaly — the MoM acceleration is live, broad, and now embedded in wage expectations. Real average hourly wages fell 0.5% MoM and 0.3% annually, which means the inflation tax on labor income is running hot enough to suppress consumption without the Fed having fired a single incremental shot.
The internal composition of this print matters as much as the headline. Core CPI came in at 2.8% YoY on a 0.4% MoM basis. That is still running well above the Fed's 2% target on an annualized basis, and critically, it did not decelerate from the prior month. The divergence between headline and core is almost entirely explained by energy — gasoline +28.4% annually, energy overall +17.9% annually, with a 3.81% MoM energy spike in April. The Iran-linked geopolitical risk premium has not been priced out of crude, which means May CPI base effects on energy will remain supportive of elevated headline prints. If energy holds even flat MoM in May, the YoY comparison will stay above 3.5% by construction.
Kevin Warsh was sworn in as FOMC Chair following Powell's May 15 departure, inheriting a committee that just produced its most divided vote since October 1992 — an 8-4 split at the April 29 meeting. Three regional presidents dissented because they want higher rates or objected to language implying future cuts. One dissent went the other direction. This is not a unified Fed; this is a Fed that is openly debating whether the next move is a hike, not a cut. The April minutes explicitly flag that market participants now assign approximately 30% probability to a rate hike by Q1 2027. That is a number that should be repriced higher given a 3.8% CPI print that arrived after those minutes were drafted.
TLT is trading at $85.30, down 0.53% YTD but up 4.01% over 52 weeks — a reflection of the volatile path long duration has taken. The current level embeds considerable rate-cut optionality that I believe is mispriced. The S&P 500 is at $7,521.68, up 9.67% YTD and 27.02% over 52 weeks — equity markets continue to price a soft-landing scenario that the inflation data does not support. Equities are either pricing in a Warsh-led pivot or ignoring the cumulative damage that 3.8% headline inflation with negative real wages does to the consumption engine. Neither interpretation strikes me as durable. The TIPS data in the verified block contains anomalous figures I cannot reconcile and will not use.
Looking forward to June 10, the May CPI release is now the single most important near-term binary. My prior watchlist item called for a headline above 3.8% with core MoM above 0.30% as the trigger to cement no-cut-2026 consensus and materially increase hike probability pricing. April delivered exactly 3.8% headline. The question for May is whether energy base effects provide even marginal relief on YoY while core MoM holds firm. If May prints at or above 3.8% on headline with core MoM at 0.30% or higher, the probability of a 2026 hike will need to be repriced from 30% toward 50%+. Warsh's first major policy speech addressing the April data directly is the other catalyst — any language referencing 'additional firming' or explicit dismissal of the easing bias language that drew dissents at the April meeting would be the verbal confirmation that the rate path has shifted regime.
