March 2026 CPI Update

Share this article

Headline CPI rose 0.87% month over month in March, in line with expectations and reflecting a 21% increase in energy goods prices as a result of higher oil prices from the Iran war. The year-over-year rate rose to 3.26%.

Core CPI (which excludes food and energy prices) increased 0.20% month over month, below expectations. And the year-over-year rate increased 2.60%.

Let’s take a closer look at Goldman Sachs Research’s breakdown of the latest data.

What’s up, what’s down?

On the softer side:

  • Used car prices declined 0.4% month over month.
  • Recreation services prices declined 0.4% (likely partially reflecting residual seasonality in the sporting events subcomponent, which declined 10% month over month).
  • Prescription drugs prices declined 1.5%.
  • Medical care services prices were flat (reflecting a 1.9% decline in home healthcare and a 1.4% decline in health insurance).
  • Legal services declined 4%.

On the stronger side:

  • Airfares rose 3%.
  • Apparel prices rose 1% (possibly reflecting tariff passthrough).
  • Owners’ equivalent rent (OER) accelerated to 0.28% (vs. 0.22% over the prior two months, reflecting payback from an unusually soft reading six months prior).
  • Software prices rose 4% month over month (after rising 4.9% month over month on average over the previous three months).

Core services excluding rent and OER rose 0.18% (vs. 0.39% on average over the prior three months).
