May PCE printed a four-handle headline and the hottest core since 2023. The Fed's own preferred gauge has now confirmed what the desk called in May: this is a services-led pipeline, not an energy spike, and it pins the Fed against the floor. The cut case is gone.

On the same day, the US pipeline ran hot beyond energy and the ECB hiked for the first time since 2023, justifying it on a broadening of price rises. The euro was sold on the hike. The 30-year held its third test in a week. Inflation is spreading past the oil story on both sides of the Atlantic, and the dollar is the relative winner.

The shorthand: core m/m 0.2% (soft, vs 0.3% consensus), headline y/y 4.2% (the base-effect re-acceleration, dead on), the 2-year unchanged at 4.14%, the 30-year holding 5.01% above the floor, gold off 2.4% on higher real yields, the dollar firm, the VIX higher, and an AI complex that was already selling into the print and that a dovish core could not rescue. A soft core is necessary for a dovish turn. It is nowhere near sufficient.

Tomorrow's May CPI is the second test of the rate floor in a week. The monthly number is set to cool while the annual rate re-accelerates, and that split is the trap. Here are the three paths the print can take, the levels that decide which one lands, and why the 30-year may hold above 5.00% either way.

The gap between what the market is pricing and what the incoming chair has spent two decades signalling is wider than at any Fed transition since 2006. That gap always closes. The path the closing takes — through communication on 17 June or through a 2-year repricing in the meantime — is the next quarter’s trade.

Strip energy, food and trade margins from the report and the structural signal still ran at the fastest pace since October 2025. Services contributed roughly 60% of the rise. The transmission window for the consumer-price impact is the June – July CPI sequence — landing on the new Fed chair’s desk in the first weeks of his term.
