PPI came in worse than the market expected. And the Fed is watching it very closely.

The number nobody wanted to see

February PPI, the US producer price index, came in at +3.4% year-on-year. The market consensus expected +2.9%. A 0.5 percentage-point difference looks like a small detail at first glance. Unfortunately, in today's situation it is not.

PPI is a precursor to inflation. It shows what producers and wholesalers pay for goods today, and what customers will pay on the shelves tomorrow.

What the number actually means

PPI measures the prices that producers receive for their products — costs that have not yet reached the consumer. It acts as a leading indicator for CPI with a lag of roughly one to three months.

+3.4% year-on-year tells us three things at once:

1) Inflationary pressure isn't just demand-driven. It's not that consumers are spending more. The pressure comes from costs like energy or transportation. And that's the kind of inflation central banks find harder to suppress.

2) The Fed doesn't have the case for quick rate cuts. Throughout the first quarter the market had been pricing in one to two cuts in 2026. After today’s number, that bet is much diminished. Every new inflation surprise extends the period of expensive money.

3) The oil shock from the Strait of Hormuz has not yet been fully reflected in the numbers. February's data captures the world before the escalation in the Middle East. The March figures, which will arrive in a month, could be even more worrying.

The market wants cheap money. Reality isn't cooperating.

The entire year of 2025 was built on one narrative in the markets: inflation is falling, the Fed will cut soon, cheap capital will return. Valuations rose. Sentiment was optimistic.

PPI at +3.4% is a sobering splash. Not a total catastrophe, but a reminder that inflation is not a linear story with a guaranteed happy ending. It's something that returns. And each time it returns, it costs investors more than before, because valuations have meanwhile risen on the assumption that it wouldn't come back.
