The July Inflation Print Lands Wednesday. Here Is What It Is Measured Against.

The Bureau of Labor Statistics publishes the July Consumer Price Index on Wednesday, August 12, at 8:30 a.m. Eastern. That timing is not a forecast. CPI release dates are set on a published calendar months ahead, which makes the print one of the few genuinely scheduled events in a market that mostly reacts to unscheduled ones.

What is worth establishing before it arrives is the baseline, because every reaction on Wednesday morning will be a comparison against numbers that already exist.

The number it is measured against

The most recent published reading covers June 2026. The all-items index fell 0.4% on the month on a seasonally adjusted basis, and rose 3.5% over the preceding twelve months before seasonal adjustment.

Those two figures do different jobs and are routinely confused. The monthly figure is seasonally adjusted and describes the change from May to June. The twelve-month figure is not seasonally adjusted and describes the change from June a year earlier. A commentator can quote either one honestly and produce two quite different impressions of the same data, which is worth remembering on Wednesday when the quoting starts.

Why the reaction usually outruns the significance

A CPI print moves rate expectations within seconds because the expectations are the thing being repriced, not the policy. The Federal Reserve has been consistent that it weighs the trend across employment, growth and prices rather than any single month. The market has been equally consistent about trading each month as though it were decisive.

Both of those can be true at once. The gap between them is where most of the volatility on a CPI morning comes from, and it is also why the first thirty minutes after 8:30 are a poor guide to what the number eventually means.

What to watch that is not the headline

The headline index absorbs energy and food, which are the two components most likely to be moving for reasons unrelated to underlying inflation. Given that crude settled about 5% higher on Monday on Strait of Hormuz uncertainty, the energy contribution to any near-term print is worth isolating rather than reading as a change in the trend.

The release itself breaks this out. Reading the components takes a few minutes longer than reading the headline, and it is the difference between knowing what happened and knowing what a single number was made of.
