Real GDP Growth Revised Up and PCE Inflation Running Slightly Below Expectations

Today (September 26), the Bureau of Economic Analysis (BEA) released monthly data on the personal consumption expenditures (PCE) price index as part of its “Personal Income and Outlays” report. Yesterday, the BEA released its revised estimate of real GDP growth in the second quarter. Taken together, the two reports show that economic growth remains realtively strong and that inflation continues to run above the Fed’s 2 percent annual target.

Taking the inflation report first, the following figure shows headline PCE inflation (the blue line) and core PCE inflation (the red line)—which excludes energy and food prices—for the period since January 2018, with inflation measured as the percentage change in the PCE from the same month in the previous year. In August, headline PCE inflation was 2.7 percent, up from 2.6 percent in July. Core PCE inflation in August was 2.9 percent, unchanged from July. Headline PCE inflation was equal to the forecast of economists surveyed, while core PCE inflation was slightly lower than forecast.

The following figure shows headline PCE inflation and core PCE inflation calculated by compounding the current month’s rate over an entire year. (The figure above shows what is sometimes called 12-month inflation, while this figure shows 1-month inflation.) Measured this way, headline PCE inflation increased from 2.0 percent in July to 3.2 percent in August. Core PCE inflation declined slightly from 2.9 percent in July to 2.8 percent in August. So, both 1-month and 12-month PCE inflation are telling the same story of inflation being well above the Fed’s target. The usual caution applies that 1-month inflation figures are volatile (as can be seen in the figure). In addition, these data likely reflect higher prices resulting from the tariff increases the Trump administration has implemented. Once the one-time price increases from tariffs have worked through the economy, inflation may decline. It’s not clear, however, how long that may take and President Trump indicated yesterday that he may impose new tariffs on pharmaceuticals, large trucks, and furniture.

Fed Chair Jerome Powell has frequently mentioned that inflation in non-market services can skew PCE inflation. Non-market services are services whose prices the BEA imputes rather than measures directly. For instance, the BEA assumes that prices of financial services—such as brokerage fees—vary with the prices of financial assets. So that if stock prices fall, the prices of financial services included in the PCE price index also fall. Powell has argued that these imputed prices “don’t really tell us much about … tightness in the economy. They don’t really reflect that.” The following figure shows 12-month headline inflation (the blue line) and 12-month core inflation (the red line) for market-based PCE. (The BEA explains the market-based PCE measure here.)


Headline market-based PCE inflation was 2.4 percent in August, unchanged from July. Core market-based PCE inflation was 2.6 percent in August, also unchanged from July. So, both market-based measures show inflation as stable but above the Fed’s 2 percent target.

In the following figure, we look at 1-month inflation using these measures. One-month headline market-based inflation increase sharply to 2.5 percent in August from 0.9 percent in July. One-month core market-based inflation increased slightly to 1.9 percent in August from 1.8 percent in July. As the figure shows, the 1-month inflation rates are more volatile than the 12-month rates, which is why the Fed relies on the 12-month rates when gauging how close it is coming to hitting its target inflation rate.


Inflation running above the Fed’s 2 percent target is consistent with relatively strong growth in real GDP. The following figure shows compound annual rates of growth of real GDP, for each quarter since the first quarter of 2023. The value for the second quarter of 2025 is the BEA’s third estimate. This revised estimate increased the growth rate of real GDP to 3.8 percent from the second estimate of 3.3 percent.

The most important contributor to real GDP growth was growth in real personal consumption expenditures, which, as shown in the following figure, increased aat compound annual rate of 2.5 percent in the second quarter, up from 0.6 percent in the first quarter.

High interest rates continue to hold back residential construction, which declined by a compound annual rate of 5.1 percent in the second quarter after declining 1.0 percent in the first quarter.

Business investment in structures, such as factories and office buildings, continued a decline that began in the first quarter of 2024.

Will the relatively strong growth in real GDP in the second quarter continue in the third quarter? Economists at the Federal Reserve Bank of Atlanta prepare nowcasts of real GDP. A nowcast is a forecast that incorporates all the information available on a certain date about the components of spending that are included in GDP. The Atlanta Fed calls its nowcast GDPNow. As the following figure from the Atlanta Fed website shows, today the GDPNow forecast is for real GDP to grow at an annual rate of 3.9 percent in the third quarter.

Finally, the macroeconomic data released in the last two days has had realtively little effect on the expectations of investors trading federal funds rate futures. Investors assign an 89.8 percent probability to the Federal Open Market Committee (FOMC) cutting its target for the federal funds rate at its meeting on October 28–29 by 0.25 percentage point (25 basis points) from its current range of 4.00 percent to 4.25 percent. That probability is only slightly lower than 91.9 percent probaiblity that investors had assigned to a 25 basis point cut a week ago. However, the probability of the committee cutting its target rate by another 25 basis points at its December 9–10 fell to 67.0 percent today from 78.6 percent one week ago.

Effect of Tariffs May Have Pushed Up CPI Inflation in June

Today (July 15), the Bureau of Labor Statistics (BLS) released its report on the consumer price index (CPI) for June. The following figure compares headline CPI inflation (the blue line) and core CPI inflation (the red line).

  • The headline inflation rate, which is measured by the percentage change in the CPI from the same month in the previous year, was 2.7 percent in June—up from 2.4 percent in May. 
  • The core inflation rate, which excludes the prices of food and energy, was 2.9 percent in June—up slightly from 2.8 percent in May. 

Headline inflation was slightly higher and core inflation was slightly lower than what economists surveyed had expected.

In the following figure, we look at the 1-month inflation rate for headline and core inflation—that is the annual inflation rate calculated by compounding the current month’s rate over an entire year. Calculated as the 1-month inflation rate, headline inflation (the blue line) surged from 1.0 percent in May to 3.5 percent in June. Core inflation (the red line) also increased sharply from 1.6 percent in May to 2.8 percent in June.

The 1-month and 12-month inflation rates are telling different stories, with 12-month inflation indicating that the rate of price increase is running moderately above the Fed’s 2 percent inflation target. The 1-month inflation rate indicates more clearly that inflation increased significantly during June. 

Of course, it’s important not to overinterpret the data from a single month. The figure shows that the 1-month inflation rate is particularly volatile. Also note that the Fed uses the personal consumption expenditures (PCE) price index, rather than the CPI, to evaluate whether it is hitting its 2 percent annual inflation target.

Does the increase in inflation represent the effects of the increases in tariffs that the Trump administration announced on April 2? (Note that some of the tariff increases announced on April 2 have since been reduced) The following figure shows 12-month inflation in three categories of products whose prices are thought to be particularly vulnerable to the effects of tariffs: apparel (the blue line), toys (the red line), and motor vehicles (the green line). To make recent changes clearer, we look only at the months since January 2021. In June, prices of apparel fell, while the prices of toys and motor vehicles rose by less than 1.0 percent.

The following figure shows 1-month inflation in these prices of these products. In June, the motor vehicles prices fell, while apparel prices increased 5.3 percent and the prices of toys soared by 24.3 percent, which was the second month in a row of very large increases in toy prices.

The 1-month inflation data for these three products are a mixed bag with two of the products showing significant increases and one showing a decline. It’s likely that some of the effects of the tariffs are still being cushioned by firms increasing their inventories earlier in the year in anticipation of price increases resulting from the tariffs. As firms draw down their inventories, we may see tariff-related increases in the prices of more goods later in the year.

To better estimate the underlying trend in inflation, some economists look at median inflation and trimmed mean inflation.

  • Median inflation is calculated by economists at the Federal Reserve Bank of Cleveland and Ohio State University. If we listed the inflation rate in each individual good or service in the CPI, median inflation is the inflation rate of the good or service that is in the middle of the list—that is, the inflation rate in the price of the good or service that has an equal number of higher and lower inflation rates. 
  • Trimmed-mean inflation drops the 8 percent of goods and services with the highest inflation rates and the 8 percent of goods and services with the lowest inflation rates. 

The following figure shows that 12-month trimmed-mean inflation (the blue line) was 3.2 percent in June, up from 3.0 percent in May. Twelve-month median inflation (the red line) 3.6 percent in June, up from 3.5 percent in May.

The following figure shows 1-month trimmed-mean and median inflation. One-month trimmed-mean inflation rose sharply from 2.2 percent in May to 3.9 percent in June. One-month median inflation also rose sharply from 2.7 percent in May to 4.1 percent in June. These data provide some confirmation that inflation likely rose from May to June.

What are the implications of this CPI report for the actions the Federal Reserve’s policymaking Federal Open Market Committee (FOMC) may take at its next meetings? Investors who buy and sell federal funds futures contracts still expect that the FOMC will leave its target for the federal funds rate unchanged at its July 29–30 meeting before cutting its target by 0.25 (25 basis points) from its current target range of 4.25 percent to 4.50 percent at its September 16–17 meeting. (We discuss the futures market for federal funds in this blog post.) The FOMC’s actions will likely depend in part on the effect of the tariff increases on the inflation rate during the coming months. If inflation were to increase significantly, it’s possible that the committee would decide to raise, rather than lower, its target range.
