THE MARCH CPI REPORT IS OUT — AND THE STORY IS MORE COMPLICATED THAN THE HEADLINE
Headline CPI surged 0.9% for the month, pushing the annual rate to 3.3% — up sharply from 2.4% in February. (CNBC) Scary number. But strip away the noise and the real story is underneath it.
Core CPI, which excludes food and energy, rose just 0.2% for the month and 2.6% year-over-year — both 0.1 percentage point below forecast. Underlying inflation was contained. (CNBC)
So what blew up the headline? One word: Iran. Gasoline prices surged a record 21.2% in March, accounting for nearly three-quarters of the overall monthly price increase — the largest monthly spike since 1967. (CNN) This isn't broad-based inflation. This is a war premium.
Core goods prices edged higher with tariff passthrough showing up in apparel, but used car prices declined for a second consecutive month and medical care prices were flat. (EY) The Fed's disinflationary forces are still working in the background.
Here's the critical context: a ceasefire between the U.S. and Iran took hold late in April, and Fed officials can now look through the March spike and concentrate on the underlying path of inflation. (CNBC) If energy prices unwind, so does most of this CPI surge.
The risk? Even if oil flows normalize, economists warn prices are "up like a rocket and down like a feather" — quick to rise in a shock, slow to fall. (CNBC) And tariff pressures aren't going anywhere.
The Fed held rates at 3.5%–3.75% at the March meeting, and seven of 19 participants now see zero cuts in 2026. (Yahoo Finance) Rate cuts aren't coming on the back of this print.
The real question isn't whether the Fed cuts soon — it's whether core inflation stays this quiet while the headline chaos fades. If it does, the second half of 2026 looks very different from the first.
