July's PCE report ticked back up — here's what the Fed's preferred inflation gauge actually says

The Bureau of Economic Analysis released its July 2026 Personal Income and Outlays report on August 26, showing that the Federal Reserve's own preferred inflation gauge — the PCE price index — ticked back up after cooling the month before. You likely saw a different inflation number two weeks earlier: July's Consumer Price Index (CPI), released August 12. They're not the same report, they don't always move together, and only one of them is the number the Fed actually targets. Here's what July's PCE report says and how to read it next to CPI instead of confusing the two.

What PCE is, and why the Fed uses it instead of CPI

PCE stands for Personal Consumption Expenditures. Like CPI, it measures how much prices changed for a broad basket of goods and services Americans buy — but it's built differently. The Federal Reserve is explicit about which one it targets: its longstanding 2% inflation goal is defined, in the Fed's own words, "as measured by the annual change in the price index for personal consumption expenditures." Not CPI. PCE.

The two indexes differ for reasons the BEA itself documents: a "scope effect" (PCE measures spending by and on behalf of the whole personal sector — households plus nonprofits serving households — while CPI measures only households' own out-of-pocket spending, so PCE picks up costs paid on someone else's behalf, like employer-sponsored health insurance); and a "formula effect" (PCE is calculated with a Fisher-Ideal formula, CPI with a modified Laspeyres formula — different math for combining the same underlying price changes into one index). That's a structural reason the two numbers tend to diverge, not a sign that either one is being calculated incorrectly.

What July's report says

Two figures matter here, the same pair that matters for CPI: the month-over-month move and the year-over-year trend.

Month-over-month, seasonally adjusted: the PCE price index rose 0.2% in July, reversing June's 0.1% decline.

Year-over-year: the PCE price index is up 3.7% over the 12 months ending in July — unchanged from June's year-over-year figure, and still well above the Fed's 2% target.

Core PCE — which strips out food and energy, the same way core CPI does — also rose 0.2% for the month and is up 3.3% year-over-year, again unchanged from June's annual core figure. So while the monthly direction flipped from a small decline to a small increase, the trailing 12-month trend held steady on both the headline and core measures.

The same release also carries income and spending data, which CPI doesn't. Personal income rose $115.1 billion (0.4%) in July, and disposable personal income (income after taxes) rose $125.9 billion (0.5%). Consumer spending (PCE — the "expenditures" the price index measures the cost of) rose $36.3 billion (0.2%) in nominal terms, down from June's 0.3% monthly pace. Once adjusted for the price changes above, real PCE rose just $1.3 billion — less than 0.1% — a sharp slowdown from June's 0.4% real increase. The personal saving rate, the share of disposable income households aren't spending, rose to 3.0% from 2.7% in June.

Read together, that combination — spending growth nearly stalling in real terms while the saving rate rose — describes households pulling back on spending growth for the month, not a spending collapse. One month doesn't establish a trend on its own.

Why PCE and CPI told slightly different stories this time

July's CPI report (covering the same reference month) showed a milder monthly move in the opposite direction of what you might expect from the headline framing: CPI rose 0.1% for the month and was up 3.4% year-over-year, with core CPI up 0.2% for the month and 2.5% year-over-year. PCE's monthly increase was larger — 0.2% versus CPI's 0.1% — and PCE's year-over-year figure (3.7%) again came in above CPI's (3.4%), continuing the pattern from June.

That gap isn't a contradiction to untangle — it's what you'd expect from two indexes with different scope and different formulas measuring overlapping but non-identical sets of purchases. The useful habit isn't picking whichever number tells a cleaner story; it's knowing which one the institution setting interest-rate policy actually watches — and that's PCE.

What this does — and doesn't — tell you

July's PCE report shows inflation, by the Fed's own preferred measure, holding steady at 3.7% year-over-year (3.3% core) even as the monthly figure flipped from a small decline to a small increase. It doesn't tell you what the Fed will do with interest rates. A single month's PCE print is one input among several the Federal Open Market Committee weighs — alongside CPI, employment data, and multiple months of trend. This report landed ahead of the Committee's September 16, 2026 meeting, where it went on to raise its target range a quarter point to 3.75%-4.00%; see this site's rate-hike explainer for what changed. Reading one report as a preview of a rate decision overstates what any single data release can tell you.

It also doesn't describe your household specifically. Like CPI, PCE is a national average built from broad spending data; it's not a receipt for what any one family paid for groceries, rent, or gas last month.

How we sourced this

Every figure above comes directly from the BEA's own July 2026 Personal Income and Outlays release — the same primary source the Fed itself cites when it defines its inflation target. We're showing our work here for the same reason we publish our scoring methodology and disclose how we make money elsewhere: a number is more useful when you can see where it came from and check it yourself, rather than take a headline percentage on faith.

The takeaway

July's PCE report — the inflation number the Federal Reserve actually targets — showed prices rising 0.2% for the month after June's 0.1% decline, with the year-over-year rate holding steady at 3.7% headline and 3.3% core. Real consumer spending growth nearly stalled while the saving rate rose to 3.0%. It's a different report from CPI, built on a different scope and a different formula, and this month PCE's monthly and annual figures both ran a bit hotter than CPI's. When you're trying to read Fed policy signals rather than just headline inflation news, PCE — not CPI — is the number worth checking first.
