CPI Inflation Worsens, as Expected

Today (September 11), the Bureau of Labor Statistics (BLS) released its report on the consumer price index (CPI) for August. 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 2.9 percent in August, up from 2.7 in July.
The core inflation rate, which excludes the prices of food and energy, was 3.1 percent in August, up slightly from 3.0 percent in July.

Headline inflation and core inflation were both the same as 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) jumped from 2.4 percent in July to 4.7 percent in August. Core inflation (the red line) increased from 3.9 percent in July to 4.2 percent in August.

The 1-month and 12-month inflation rates are both indicating that inflation accelerated in August. Core inflation—which is often a good indicator of future inflation—in particular has been running well above the Fed’s 2 percent inflation target during the last two months.

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.

Core inflation had been running significantly higher than headline inflation in the past few months because gasoline prices had generally been falling since February. Gasoline prices turned around in August, however, increasing at a 25.5 percent annual rate. As shown in the following figure, 1-month inflation in gasoline prices moves erratically—which is the main reason that gasoline prices aren’t included in core inflation.

Does the increase in inflation represent the effects of the increases in tariffs that the Trump administration announced on April 2? (Note that many of the tariff increases announced on April 2 have since been reduced) The following figure shows 12-month inflation in durable goods—such as furniture, appliances, and cars—which are likely to be affected directly by tariffs, and services, which are less likely to be affected by tariffs.. To make recent changes clearer, we look only at the months since January 2022. In August, inflation in durable goods increased to 1.9 percent from 1.2 percent in July. Inflation in services in August was 3.8 percent, unchanged from July.

The following figure shows 1-month inflation in the prices of these products, which may make the effects of tariffs clearer. In August, durable goods inflation was 5.1 percent up from 4.5 percent in July. Service inflation was 3.9 percent in August, down slightly from 4.0 percent in July. Inflation in goods and services both running well above 2 percent is not good news for inflation falling back to the Fed’s 2 percent target in the near future.

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 3.3 percent in August, up slightly from 3.2 July. Twelve-month median inflation (the red line) 3.6 percent in August, unchanged from July.

The following figure shows 1-month trimmed-mean and median inflation. One-month trimmed-mean inflation rose from 2.9 percent in July to 3.2 percent in August. One-month median inflation remained unchanged at 3.4 percent in August. These data are consistent with the view that inflation is running above the Fed’s 2 percent target.

The CPI inflation data combined with the recent jobs data (which we discuss here and here), indicate that the U.S. economy may be entering a period of stagflation—a combination of rising inflation with falling, or stagnating, output. Stagflation poses a policy dilemma for the Fed’s policymaking Federal Open Market Committee (FOMC) because cutting its target for the federal funds rate to increase economic growth and employment may worsen inflation. At this point, it seems likely that the FOMC will “look through” this month’s rising inflation because it may be largely due to one-time price increases caused by tariffs. Committee members have signaled that they are likely to cut their target for the federal funds rate by 0.25 percent (25 basis points) at the conclusion of their meeting on September 16–17 and again at the conclusion of the following meeting on October 28–29.

PCE Inflation Is Steady, but Still Above the Fed’s Target

On August 29, the Bureau of Economic Analysis (BEA) released data for July on the personal consumption expenditures (PCE) price index as part of its “Personal Income and Outlays” report. 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 January 2017, with inflation measured as the percentage change in the PCE from the same month in the previous year. In July, headline PCE inflation was 2.6 percent, unchanged from June. Core PCE inflation in July was 2.9 percent, up slightly from 2.8 percent in June. Headline PCE inflation and core PCE inflation were both equal to what economists surveyed had 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 fell from 3.5 percent in June to 2.4 percent in July. Core PCE inflation increased slightly from 3.2 percent in June to 3.3 percent in July. So, both 1-month PCE inflation estimates are above the Fed’s 2 percent target, with 1-month core PCE inflation being well above target. The usual caution applies that 1-month inflation figures are volatile (as can be seen in the figure), so we shouldn’t attempt to draw wider conclusions from one month’s data. In addition, these data may 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 it’s likely that not all the effects of the tariff increases on the price level are reflected in this month’s data.

As usual, we need to note that 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 2.3 percent in July, unchanged from June. Core market-based PCE inflation was 2.6 percent in July, also unchanged from June. 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 declined sharply to 1.1 percent in July from 4.1 percent in June. One-month core market-based inflation also declined sharply to 2.1 percent in July from 3.8 percent in June. 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. Still, looking at 1-month inflation gives us a better look at current trends in inflation, which these data indicate is slowing significantly.

As we noted earlier, some of the increase in inflation is likely attributable to the effects of tariffs. The effect of tariffs are typically seen in goods prices, rather than in service prices because tariffs are levied primarily on imports of goods. As the following figure shows, one-month inflation in goods prices jumped in June to 4.8 percent, but then declined sharply to –1.6 in July. One-month inflation in services prices increased from 2.9 percent in June to 4.3 percent in July. Clearly, the 1-month inflation data—particularly for goods—are quite volatile.

Finally, these data had little effect on the expectations of investors trading federal funds rate futures. Investors assign an 86.4 percent probability to the Federal Open Market Committee (FOMC) cutting its target for the federal funds rate at its meeting on September 16–17 by 0.25 percentage point (25 basis points) from its current range of 4.25 percent to 4.5o percent. There has been some speculation in the business press that the FOMC might cut its target by 50 basis points at that meeting, but with inflation remaining above target, investors don’t foresee a larger cut in the target range happening.

In Jackson Hole Speech, Fed Chair Powell Signals a Rate Cut and Introduces the Fed’s Revised Monetary Policy Framework

Federal Reserve chairs often take the opportunity of the Kansas City Fed’s annual monetary policy symposium held in Jackson Hole, Wyoming to provide a summary of their views on monetary policy and on the state of the economy. In these speeches, Fed chairs are careful not to preempt decisions of the Federal Open Market Committee (FOMC) by stating that policy changes will occur that the committee hasn’t yet agreed to. In his speech at Jackson Hole today (August 22), Powell came about as close as Fed chairs ever do to announcing a policy change in a speech. In addition, Powell announced changes to the Fed’s monetary policy framework that had been in place since 2020.

Congress has given the Federal Reserve a dual mandate to achieve price stability and maximum employment. To reach its goal of price stability, the Fed has set an inflation target of 2 percent, with inflation being measured by the percentage change in the personal consumption expenditures (PCE) price index. In the statement that the FOMC releases after each meeting, it generally indicates the current “balance of risks” to meeting its two goals. In a press conference on July 30 following the last meeting of the FOMC, Powell stated that while the labor market appeared to be in balance at close to maximum employment, inflation was still running above the Fed’s 2 percent annual target.

In today’s speech, Powell stated that “the balance of risks appears to be shifting” and “that downside risks to employment are rising. And if those risks materialize, they can do so quickly in the form of sharply higher layoffs and rising unemployment.” These statements seem to signal that he expects that at its next meeting on September 16–17 the FOMC will cut its target for the federal funds rate from its current range of 4.25 percent to 4.50 percent.

One indication of expectations of future changes in the FOMC’s target for the federal funds rate comes from investors who buy and sell federal funds futures contracts. (We discuss the futures market for federal funds in this blog post.) Yesterday, investors assigned a 75.0 percent probability to the committee cutting its target by 0.25 percentage point (25 basis points) to a range of 4.00 percent to 4.25 percent at its September meeting. After Powell’s speech at 10 a.m. eastern time, the probability of a 25 basis point cut increased to 85.3 percent. As the following figure from the Wall Street Journa shows, the stock market also jumped, with the S&P 500 stock index having increased about 1.5 percent at 2:00 p.m. Investors were presumably expecting that by cutting its federal funds rate target, the FOMC would help to offset some of the current weakness in the labor market. (We discussed the weakness in the latest jobs report in this blog post.)

Powell also announced that the Fed had revised its monetary policy framework, which had been in place since 2020. The previous framework was called flexible average-inflation targeting (FAIT). The policy was intended to automatically make monetary policy expansionary during recessions and contractionary during periods of unexpectedly high inflation. If households and firms accept that the Fed is following this policy, then during a recession when the inflation rate falls below the target, they would expect that the Fed would take action to increase the inflation rate. If a higher inflation rate results in a lower real interest rate, there will be an expansionary effect on the economy. Similarly, if the inflation rate were above the target, households and firms would expect future inflation rates to be lower, raising the real interest rate, which would have a contractionary effect on the economy.

An important point to note is that with a FAIT policy, after a period in which inflation is below 2%, the Fed would aim to keep inflation above 2% for a time to “make up” for the period of low inflation. But the converse would not be true—if inflation runs above 2%, the Fed would attempt to bring the inflation back to 2%, but would not push inflation below 2% for a time to make up for the period of low inflation. The result is that, on average, the economy would run “hotter,” lowering the average unemployment rate over time. Many policymakers at the Fed believed that, in the years before 2019, the unemployment could have been lower without causing the inflation rate to be persistently above the Fed’s target.

With hindsight, some economists and policymakers argue that FAIT was implemented at just the wrong time. The policy was designed to address the problem of inflation running below the 2% target for most of the period between 2012 and 2019, resulting in unemployment being higher than was consistent with the Fed’s mandate for maximum employment. But, in fact, as the following figure shows, in 2020 the U.S. economy was about to enter a period with the highest inflation rates since the early 1980s.

In his speech today, Powell noted that:

“The economic conditions that brought the policy rate to the ELB [effective lower bound to the federal funds rate, 0 percent to 0.25 percent] and drove the 2020 framework changes were thought to be rooted in slow-moving global factors that would persist for an extended period—and might well have done so, if not for the pandemic. … In the event, rather than low inflation and the ELB, the post-pandemic reopening brought the highest inflation in 40 years to economies around the world.”

Powell outlined the key changes in the policy framework:

“First, we removed language indicating that the ELB was a defining feature of the economic landscape. Instead, we noted that our ‘monetary policy strategy is designed to promote maximum employment and stable prices across a broad range of economic conditions.'”

“Second, we returned to a framework of flexible inflation targeting and eliminated the ‘makeup’ strategy. As it turned out, the idea of an intentional, moderate inflation overshoot [after a period when inflation had been below the 2 percent annual target] had proved irrelevant. … Our revised statement emphasizes our commitment to act forcefully to ensure that longer-term inflation expectations remain well anchored, to the benefit of both sides of our dual mandate. It also notes that ‘price stability is essential for a sound and stable economy and supports the well-being of all Americans.’ “

“Third, our 2020 statement said that we would mitigate ‘shortfalls,’ rather than ‘deviations,’ from maximum employment. … [T]he use of ‘shortfalls’ was not intended as a commitment to permanently forswear preemption or to ignore labor market tightness. Accordingly, we removed ‘shortfalls’ from our statement. Instead, the revised document now states more precisely that ‘the Committee recognizes that employment may at times run above real-time assessments of maximum employment without necessarily creating risks to price stability.’ … [But] preemptive action would likely be warranted if tightness in the labor market or other factors pose risks to price stability.”

“Fourth, consistent with the removal of ‘shortfalls,’ we made changes to clarify our approach in periods when our employment and inflation objectives are not complementary. In those circumstances, we will follow a balanced approach in promoting them.”

“Finally, the revised consensus statement retained our commitment to conduct a public review roughly every five years.”

To summarize, the two key changes in the framework are: 1) The FOMC will no longer attempt to push inflation beyond its 2 percent goal if inflation has been below that goal for a period, and 2) The FOMC may still attempt to preempt an increase in inflation if labor market conditions or other data make it appear likely that inflation will accelerate, but it won’t necessarily do so just because the unemployment rate is currently lower than what had been considered consistent with maximum employment.

CPI Inflation Comes in Slightly Below Expectations, Increasing Likelihood of Fed Rate Cuts

Fed Chair Jerome Powell (left) and Vice Chair Philip Jefferson (photo from federalreserve.gov)

Today (August 12), the Bureau of Labor Statistics (BLS) released its report on the consumer price index (CPI) for July. 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 July, unchanged from June.
The core inflation rate, which excludes the prices of food and energy, was 3.0 percent in July, up slightly from 2.9 percent in June. (Note that there was some inconsistency in how the core inflation rate is reported. The BLS, and some news outlets, give the value as 3.1 percent. The unrounded value is 3.0486 percent.)

Headline inflation and core inflation were 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) declined from 3.5 percent in June to 2.4 percent in July. Core inflation (the red line) increased from 2.8 percent in June to 3.9 percent in July.

The 1-month and 12-month inflation rates are telling somewhat different stories, with 12-month inflation indicating that inflation is stable, although moderately above the Fed’s 2 percent inflation target. The 1-month core inflation rate indicates that inflation may have increased during July.

A key reason for core inflation being significantly higher than headline inflation is that gasoline prices declined by 23.1 percent at an annual rate in June. As shown in the following figure, 1-month inflation in gasoline prices moves erratically—which is the main reason that gasoline prices aren’t included in core inflation.

Does the increase in inflation represent the effects of the increases in tariffs that the Trump administration announced on April 2? (Note that many 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 July, 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 July, motor vehicles prices and apparel prices increased by less than 1 percent, while toy prices increased by 1.9 percent after having soared soared by 24.3 percent in June. At least for these three products, it’s difficult to see tariffs as having had a significant effect on inflation in July.

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 July, unchanged from June. Twelve-month median inflation (the red line) 3.6 percent in July, unchanged from June.

The following figure shows 1-month trimmed-mean and median inflation. One-month trimmed-mean inflation declined from 3.9 percent in June to 2.9 percent in July. One-month median inflation also declined from 4.1 percent in June to 3.7 percent in July. These data indicate that inflation may have slowed in July (the opposite conclusion we noted earlier when discussing 1-month core inflation), while remaining above the Fed’s 2 percent target.

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? Even before today’s relatively favorable, if mixed, inflation report, the unexpectedly weak jobs report at the beginning of the month (which we discuss in this blog post) made it likely that the FOMC would soon begin cutting its target for the federal funds rate.

Investors who buy and sell federal funds futures contracts assign a probability of 94.3 percent to FOMC cutting its target for the federal funds rate at its September 16–17 meeting by 0.25 (25 basis points) from its current target range of 4.25 percent to 4.50 percent. That probability increased from 85.9 percent yesterday. (We discuss the futures market for federal funds in this blog post.) Investors assign a probability of 61.5 percent to the FOMC cutting its target again by 25 basis points at its October 28–29 meeting, and a probability of 50.3 percent to a third 25 basis point cut at the committee’s December 9–10 meeting.

PCE Inflation Comes in Higher Than Expected

Yesterday, in this blog post, we discussed the quarterly data on inflation as measured by changes in the personal consumption expenditures (PCE) price index. Today (July 31), the Bureau of Economic Analysis (BEA) released monthly data on the PCE price index as part of its “Personal Income and Outlays” report. 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 January 2017, with inflation measured as the percentage change in the PCE from the same month in the previous year. In June, headline PCE inflation was 2.6 percent, up from 2.4 percent in May. Core PCE inflation in June was 2.8 percent, unchanged from May. Headline PCE inflation was higher than the forecast of economists surveyed, while core PCE inflation was the same as 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 jumped from 2.0 percent in May to 3.4 percent in June. Core PCE inflation increased from 2.6 percent in May to 3.1 percent in June. So, both 1-month PCE inflation estimates are well above the Fed’s 2 percent target. The usual caution applies that 1-month inflation figures are volatile (as can be seen in the figure), so we shouldn’t attempt to draw wider conclusions from one month’s data. In addition, these data likely don’t capture fully the higher prices likely to result from the tariff increases the Trump administration has implemented, including those in trade agreements that have only been announced in the past few days.

Fed Chair Jerome Powell has frequently noted 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 2.3 percent in June, up from 2.1 percent in May. Core market-based PCE inflation was 2.6 percent in June, up from 2.4 percent in May. So, both market-based measures show similar rates of inflation in June as the total measures do. In the following figure, we look at 1-month inflation using these measures. The 1-month inflation rates are both higher than the 12-month rates. One-month headline market-based inflation soared to 3.9 percent in June from 1.6 percent in May. One-month core market-based inflation also increased sharply to 3.6 percent in June from 2.2 percent in May. 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. Still, looking at 1-month inflation gives us a better look at current trends in inflation, which these data indicate is rising significantly.

Is the increase in inflation attributable to the effects of tariffs? At this point, it’s too early to tell, particularly since, as noted earlier, all tariff increases have not yet been implemented. We can note, though, that the effect of tariffs are typically seen in goods prices, rather than in service prices because tariffs are levied primarily on imports of goods. As the following figure shows, one-month inflation in goods prices jumped from 0.9 percent in May to 4.8 percent in June, while one-month inflation in services prices increased only from 2.5 percent in May to 2.8 percent in June.

Finally, we noted in a blog post yesterday that investors trading federal funds rate futures assigned a 55.0 percent probability to the Federal Open Market Committee leaving its target for the federal funds rate unchanged at its meeting on September 16–17. With today’s PCE report showing higher than expected inflation, that probability has increased to 60.8 percent.

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

Image generated by ChatGTP-4o

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.

Mixed PCE Inflation Report and Slowing Growth Provides Murky Outlook for the Fed

Image generated by ChatGTP-4o

Today (June 27), the BEA released monthly data on the personal consumption expenditures (PCE) price index as part of its “Personal Income and Outlays” report. 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 January 2016, with inflation measured as the percentage change in the PCE from the same month in the previous year. In May, headline PCE inflation was 2.3 percent, up from 2.2 percent in April. Core PCE inflation in May was 2.7 percent, up from 2.6 percent in April. Headline PCE inflation was equal to the forecast of economists surveyed, while core PCE inflation was slightly higher than forecast.

The following figure shows 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, PCE inflation increased in from 1.4 percent in April to 1.6 percent in May. Core PCE inflation also increased from 1.6 percent in April to 2.2 percent in May. So, both 1-month PCE inflation estimates are close to the Fed’s 2 percent target. The usual caution applies that 1-month inflation figures are volatile (as can be seen in the figure), so we shouldn’t attempt to draw wider conclusions from one month’s data. In addition, these data likely don’t capture fully the higher prices likely to result from the tariff increases the Trump administration announced on April 2.

Headline market-based PCE inflation was 2.1 percent in May, up from 1.9 percent in April. Core market-based PCE inflation was 2.4 percent in May, up from 2.3 percent in April. So, both market-based measures show similar rates of inflation in May as the total measures do. In the following figure, we look at 1-month inflation using these measures. The 1-month inflation rates are both lower than the 12-month rates. One-month headline market-based inflation was 1.5 percent in May, down from 2.3 percent in April. One-month core market-based inflation was 2.1 percent in May, down from 2.7 percent in April. 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.

Earlier this week, the BEA released a revised estimate of real GDP growth during the first quarter of 2025—January through March. The BEA’s advance estimate, released on April 30, was that real GDP fell by 0.3 percent in the first quarter, measured at an annual rate. (We discussed the BEA’s advance estimate in this blog post.) The BEA’s revised estimate is that real GDP fell by 0.5 percent in the first quarter. The following figure shows the current estimated rates of real GDP growth in each quarter beginning in 2021.

As we noted in our post discussing the advance estimate, one way to strip out the effects of imports, inventory investment, and government purchases—which can all be volatile—is to look at real final sales to private domestic purchasers, which includes only spending by U.S. households and firms on domestic production. According to the advance estimate, real final sales to private domestic purchasers increased by 3.0 percent in the first quarter of 2025. According to the revised estimate, real final sales to private domestic purchasers increased by only 1.9 percent in the first quarter, down from 2.9 percent growth in the fourth quarter of 2024. These revised data indicate that economic growth likely slowed in the first quarter.

In summary, this week’s data provide some evidence that the inflation rate is getting close to the Fed’s 2 percent annual target and that economic growth may be slowing. Do these data make it more likely that the Fed’s policymaking Federal Open Market Committee (FOMC) will cut its target for the federal funds rate relatively soon?

Investors who buy and sell federal funds futures contracts still expect that the FOMC will leave its federal funds rate target unchanged at its next meetings on July 29–30 and September 16–17. Investors expect that the committee will cut its target at its October 28–29 meeting. (We discuss the futures market for federal funds in this blog post.) There remains a possibility, though, that future macroeconomic data releases, such as the June employment data to be released on July 3, may lead the FOMC to cut its target rate sooner.

The FOMC Leaves Its Target for the Federal Funds Rate Unchanged While Still Projecting Two Rate Cuts This Year

Members of the Fed’s policymaking Federal Open Market Committee (FOMC) had signaled clearly before today’s (June 18) meeting that the committee would leave its target range for the federal funds rate unchanged at 4.25 percent to 4.50 percent. In the statement released after its meeting, the committee noted that a key reason for keeping its target range unchanged was that: “Uncertainty about the economic outlook has diminished but remains elevated.” Committee members were unanimous in voting to keep its target range unchanged.

In his press conference following the meeting, Fed Chair Jerome Powell indicated that a key source of economic uncertainty was the effect of tariffs on the inflation rate. Powell indicated that the likeliest outcome was that tariffs would lead to the inflation rate temporarily increasing. He noted that: “Beyond the next year or so, however, most measures of longer-term expectations [of inflation] remain consistent with our 2 percent inflation goal.”

The following figure shows, for the period since January 2010, the upper bound (the blue line) and lower bound (the green line) for the FOMC’s target range for the federal funds rate and the actual values of the federal funds rate (the red line) during that time. Note that the Fed has been successful in keeping the value of the federal funds rate in its target range. (We discuss the monetary policy tools the FOMC uses to maintain the federal funds rate in its target range in Macroeconomics, Chapter 15, Section 15.2 (Economics, Chapter 25, Section 25.2).)

After the meeting, the committee also released a “Summary of Economic Projections” (SEP)—as it typically does after its March, June, September, and December meetings. The SEP presents median values of the 18 committee members’ forecasts of key economic variables. The values are summarized in the following table, reproduced from the release.

There are several aspects of these forecasts worth noting:

Committee members reduced their forecast of real GDP growth for 2025 from 1.7 percent in March to 1.4 percent today. (It had been 2.1 percent in their December forecast.) Committee members also slightly increased their forecast of the unemployment rate at the end of 2025 from 4.4 percent to 4.5 percent. (The unemployment rate in May was 4.2 percent.)
Committee members now forecast that personal consumption expenditures (PCE) price inflation will be 3.0 percent at the end of 2025. In March they had forecast that it would be 2.7 percent at the end of 2025, and in December, they had forecast that it would 2.5 percent. Similarly, their forecast of core PCE inflation increased from 2.8 percent to 3.1 percent. It had been 2.5 percent in December. The committee does not expect that PCE inflation will decline to the Fed’s 2 percent annual target until sometime after 2027.
The committee’s forecast of the federal funds rate at the end of 2025 was unchanged at 3.9 percent. The federal funds rate today is 4.33 percent, which indicates that the median forecast of committee members is for two 0.25 percentage point (25 basis points) cuts in their target for the federal funds rate this year. Investors are similarly forecasting two 25 basis point cuts.

During his press conference, Powell indicated that because the tariff increases the Trump administration implemented beginning in April were larger than any in recent times, their effects on the economy are difficult to gauge. He noted that: “There’s the manufacturer, the exporter, the importer and the retailer and the consumer. And each one of those is going to be trying not to be the one to pay for the tariff, but together they will all pay together, or maybe one party will pay it all.” The more of the tariff that is passed on to consumers, the higher the inflation rate will be.

Earlier today, President Trump reiterated his view that the FOMC should be cutting its target for the federal funds rate, labeling Powell as “stupid” for not doing so. Trump has indicated that the Fed should cut its target rate by 1 percentage point to 2.5 percentage points in order to reduce the U.S. Treasury’s borrowing costs. During World War II and the beginning of the Korean War, the Fed pegged the interest rates on Treasury securities at low levels: 0.375 percent on Treasury bills and 2.5 percent on Treasury bonds. Following the Treasury-Federal Reserve Accord, reached in March 1951, the Federal Reserve was freed from the obligation to fix the interest rates on Treasury securities. (We discuss the Accord in Chapter 13 of Money, Banking, and the Financial System.) Since that time, the Fed has focused on its dual mandate of maximum employment and price stability and it has not been directly concerned with affecting the Treasury’s borrowing cost.

Barring a sharp slowdown in the growth of real GDP, a significant rise in the unemployment rate, or a significant rise in the inflation rate, the FOMC seems unlikely to change its target for the federal funds rate before its meeting on September 16–17 at the earliest.

PCE Inflation Slowed More than Expected in April

Today (May 30), the BEA released monthly data on the personal consumption expenditures (PCE) price index as part of its “Personal Income and Outlays” report. 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 2016, with inflation measured as the percentage change in the PCE from the same month in the previous year. In April, PCE inflation was 2.1 percent, down from 2.3 percent in March. Core PCE inflation in April was 2.5 percent, down from 2.7 percent in March. Headline PCE inflation was below the forecast of economists surveyed, while core PCE inflation was consistent with the forecast.

The following figure shows 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, PCE inflation increased in April to 1.2 percent from 0.1 percent in March. Core PCE inflation also increased from 1.1 percent in March to 1.4 percent in April. So, both 1-month PCE inflation estimates are well below the Fed’s 2 percent target. The usual caution applies that 1-month inflation figures are volatile (as can be seen in the figure), so we shouldn’t attempt to draw wider conclusions from one month’s data. In addition, because these data are for April, they don’t capture fully the price increases resulting from the tariff increases the Trump administration announced on April 2.

Fed Chair Jerome Powell has noted that inflation in non-market services has been high. 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 1.9 percent in April, unchanged from March. Core market-based PCE inflation was 2.3 percent in April, which was also unchanged from March. So, both market-based measures show about the same rate of inflation in April as the total measures do. In the following figure, we look at 1-month inflation using these measures. The 1-month inflation rates are both higher than the 12-month rates. Headline market-based inflation was 2.6 percent in April, up from 0.1 percent in March. Core market-based inflation was 3.1 percent in April, up from 1.2 percent in March. 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.

In summary, today’s data provide some evidence that the inflation rate is getting closer to the Fed’s 2 percent annual target. Improving inflation combined with some indications that output growth is slowing—the BEA release indicated that growth in real consumption expenditures slowed in April—might make it more likely that the Fed’s policymaking Federal Open Market Committee (FOMC) will cut its target for the federal funds rate relatively soon.

However, investors who buy and sell federal funds futures contracts expect that the FOMC will leave its federal funds rate target unchanged at its next meetings on June 17–18 and July 29–30. (We discuss the futures market for federal funds in this blog post.) Investors assign a probability 0f 72.6 percent to the FOMC cutting its target at its September 29–30 meeting. Investor expectations reflect the recent statements from Fed Chair Jerome Powell and other members of the FOMC that they intend to wait until the effects of the tariff increases on the economy are clearer before changing the target for the federal funds rate.

Consumer Expectations of Inflation Have Jumped. How Accurately Have They Forecast Past Inflation?

Since 1946, the Institute for Social Research (ISR) at the University of Michigan has conducted surveys of consumers. Each month, the ISR interviews a nationwide sample of 900 to 1,000 consumers, asking a variety of questions, including some on inflation.

The results of the University of Michigan surveys are widely reported in the business press. In the latest ISR survey it’s striking how much consumers expect inflation to increase. The median response by those surveyed to the question “By about what percent do you expect prices to go up/down on the average, during the next 12 months?” was 7.3 percent. If this expectation were to prove to be correct, inflation, as measured by the percentage change in the consumer price index (CPI), will have to more than double from its April value of 2.3 percent.

How accurately have consumers surveyed by the ISR predicted future inflation? The question is difficult to answer definitively because the survey question refers only to “prices” rather than to a measure of the price level, such as the consumer price index (CPI). Some people may have the CPI in mind when answering the question, but others may think of the prices of goods they buy regularly, such as groceries or gasoline. Nevertheless, it can be interesting to see how well the responses to the ISR survey match changes in the CPI, which we do in the following figure for the period from January 1978—when the survey began—to April 2024—the last month for which we have CPI data from the month one year in the future.

The blue line shows consumers’ expectations of what the inflation rate will be over the following year. The red line shows the inflation rate in a particular month calculated as the percentage change in the CPI from the same month in the previous year. So, for instance, in February 2023, consumers expected the inflation rate over the next 12 months to be 4.2 percent. The actual inflation, measured as the percentage change in the CPI between February 2023 and February 2024 was 3.2 percent.

The figure shows that consumers forecast inflation reasonably well. As a simple summary, the average inflation rate consumers expected over this whole period was 3.6 percent, while the actual inflation rate was 3.5 percent. So, for the period as a whole, the inflation rate that consumers expected was about the same as the actual inflation rate. The most persistent errors occurred during the recovery from the Great Recession of 2007–2008, particularly the five years from 2011 to 2016. During those five years, consumers expected inflation to be 2.5 percent or more, whereas actual inflation was typically below 2 percent.

Consumers also missed the magnitude of dramatic changes in the inflation rate. For instance, consumers did not predict how much the inflation would increase during the 1978 to 1980 period or during 2021 and early 2022. Similarly, consumers did not expect the decline in the price level from March to October 2009.

The two most recent expected inflation readings are 6.5 percent in April and, as noted earlier, 7.3 percent in May. In other words, the consumers surveyed are expecting inflation in April and May 2026 to be much higher than the 2 percent to 3 percent inflation rate most economists and Fed policymakers expect. For example, in March, the median forecast of inflation at the end of 2026 by the members of the Fed’s policymaking Federal Open Market Committee (FOMC) was only 2.2 percent. (Note, though, that FOMC members are projecting the percentage change in the personal consumption expenditures (PCE) price index rather than the percentage change in the CPI. CPI inflation has typically been higher than PCE inflation. For instance, in the period since January 1978, average CPI inflation was 3.6 percent, while average PCE inflation was 3.1 percent).

If economists and policymakers are accurately projecting inflation in 2026, it would be an unusual case of consumers in the ISR survey substantially overpredicting the rate of inflation. One possibility is that news reports of the effect of the Trump Administration’s tariff policies on the inflation rate may have caused consumers to sharply increase the inflation rate they expect next year. If, as seems likely, the tariff increases end up being much smaller than those announced on April 2, the inflation rate in 2026 may be lower than the consumers surveyed expect.
