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.

Real GDP Growth in the Second Quarter Comes in Higher than Expected

This morning (July 30), the Bureau of Economic Analysis (BEA) released its advance estimate of real GDP for the first quarter of 2025. (The report can be found here.) The BEA estimates that real GDP increased by 3.0 percent, measured at an annual rate, in the second quarter—April through June. Economists surveyed had expected a 2.4 percent increase. Real GDP declined by an estimated 0.5 percent in the first quarter of 2025, so the increase in the second quarter represents a strong rebound in economic growth. The following figure shows the estimated rates of GDP growth in each quarter beginning with the first quarter of 2021.

As the following figure—taken from the BEA report—shows, the decrease in imports in the second quarter was the most important factor contributing to the increase in real GDP. During the first quarter, imports had soared as businesses tried to stay ahead of what were expected to be large tariff increases implement by the Trump Administration. Consumption spending increased in the second quarter, while investment spending and exports decreased.

It’s notable that real private inventories declined by $29.6 billion in the second quarter after having increased by $2070 billion in the first quarter. Again, it’s likely that the large swings in inventories represented firms stockpiling goods in the first quarter in anticipation of the tariff increases and then drawing down those stockpiles in the second quarter.

One way to strip out the effects of imports, inventory investment, and government purchases—which can also be volatile—is to look at real final sales to domestic purchasers, which includes only spending by U.S. households and firms on domestic production. As the following figure shows, real final sales to domestic purchasers increased by 1.2 percent in the second quarter of 2025, which was a decrease from the 1.9 percent increase in the first quarter. The large difference between the change in real GDP and the change in real final sales to domestic purchasers is an indication of how strongly the data on national income in the first two quarters of 2025 were affected by businesses anticipating tariff increases. Compared with data on real GDP, data on real final sales to domestic purchasers shows the economy doing significantly better in the first quarter and significantly worse in the second quarter.

The BEA report this morning included quarterly data on the personal consumption expenditures (PCE) price index. The Fed relies on annual changes in the PCE price index to evaluate whether it’s meeting its 2 percent annual inflation target. 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 the first quarter of 2018, with inflation measured as the percentage change in the PCE from the same quarter in the previous year. In the second quarter, headline PCE inflation was 2.4 percent, down slightly from 2.5 percent in the first quarter. Core PCE inflation in the second quarter was 2.7 percent, down from 2.8 percent in the first quarter. Both headline PCE inflation and core PCE inflation remained above the Fed’s 2 percent annual inflation target.

The following figure shows quarterly PCE inflation and quarterly core PCE inflation calculated by compounding the current quarter’s rate over an entire year. Measured this way, headline PCE inflation decreased from 3.7 percent in the first quarter of 2025 to 2.1 percent in the second quarter. Core PCE inflation decreased from 3.5 percent in the first quarter of 2025 to 2.5 percent in the secondt quarter. Measured this way, headline PCE inflation in the second quarter was close to the Fed’s target, while core PCE was well above the target. As we discuss in this blog post, tariff increases result in an aggregate supply shock to the economy. As a result, we may see a significant increase in inflation in the coming months as the higher tariff rates that have been negotiated recently begin to be implemented.

Real GDP Declines and Inflation Data Are Mixed in Latest BEA Releases

This morning (April 30), the Bureau of Economic Analysis (BEA) released its advance estimate of GDP for the first quarter of 2025. (The report can be found here.) The BEA estimates that real GDP fell by 0.3 percent, measured at an annual rate, in the first quarter—January through March. Economists surveyed had expected an 0.8 percent increase. Real GDP grew by an estimated 2.5 percent in the fourth quarter of 2024. The following figure shows the estimated rates of GDP growth in each quarter beginning in 2021.

As the following figure—taken from the BEA report—shows, the increase in imports was the most important factor contributing to the decline in real GDP. The quarter ended before the Trump Administration announced large tariff increases on April 2, but the increase in imports is likely attributable to firms attempting to beat the tariff increases they expected were coming.

It’s notable that the change in real private inventories was a large $140 billion, which contributed 2.3 percentage points to the change in real GDP. Again, it’s likely that the large increase in inventories represented firms stockpiling goods in anticipation of the tariff increases.

One way to strip out the effects of imports, inventory investment, and government purchases—which can also be volatile—is to look at real final sales to domestic purchasers, which includes only spending by U.S. households and firms on domestic production. As the following figure shows, real final sales to domestic purchasers increase by 3.0 percent in the first quarter of 2024, which was a slight increase from the 2.9 percent increase in the fourth quarter of 2024. The large difference between the change in real GDP and the change in real final sales to domestic purchasers is an indication of how strongly this quarter’s national income data were affected by businesses anticipating the tariff increases.

In the separate “Personal Income and Outlays” report that the BEA also released this morning, the bureau reported monthly data on the personal consumption expenditures (PCE) price index. The Fed relies on annual changes in the PCE price index to evaluate whether it’s meeting its 2 percent annual inflation target. The following figure shows PCE inflation (the blue line) and core PCE inflation (the red line)—which excludes energy and food prices—for the period since January 2017 with inflation measured as the percentage change in the PCE from the same month in the previous year. In March, PCE inflation was 2.3 percent, down from 2.7 percent in February. Core PCE inflation in March was 2.6 percent, down from 3.0 percent in February. Both headline and core PCE inflation were higher than the forecasts of economists surveyed.

The BEA also released quarterly PCE data as part of its GDP report. The following figure shows quarterly headline PCE inflation (the blue line) and core PCE inflation (the red line). Inflation is calculated as the percentage change from the same quarter in the previous year. Headline PCE inflation in the first quarter was 2.5 percent, unchanged from the fourth quarter of 2025. Core PCE inflation was 2.8 percent, also unchanged from the fourth quarter of 2025. Both measures were still above the Fed’s 2 percent inflation target.

The following figure shows quarterly PCE inflation and quarterly core PCE inflation calculated by compounding the current quarter’s rate over an entire year. Measured this way, headline PCE inflation increased from 2.4 percent in the fourth quarter of 2024 to 3.6 percent in the first quarter of 2025. Core PCE inflation increased from 2.6 percent in the fourth quarter of 2024 to 3.5 percent in the first quarter of 2025. Clearly, the quarterly data show significantly higher inflation than do the monthly data. As we discuss in this blog post, tariff increases result in an aggregate supply shock to the economy. As a result, unless the current and scheduled tariff increases are reversed, we will likely see a significant increase in inflation in the coming months. So, neither the monthly nor the quarterly PCE data may be giving a good indication of the course of future inflation.

What should we make of today’s macro data releases? First, it’s important to remember that these data will be subject to revisions in coming months. If we are heading into a recession, the revisions may well be very large. Second, we are sailing into unknown waters because the U.S. economy hasn’t experienced tariff increases as large as these since passage of the Smoot-Hawley Tariff in 1930. Third, at this point we don’t know whether some, most, all, or none of the tariff increases will be reversed as a result of negotiations during the coming weeks. Finally, on Friday, the Bureau of Labor Statistics will release its “Employment Situation Report” for March. That report will provide some additional insight into the state of the economy—as least as it was in March before the full effects of the tariffs have been felt.
