CPI Inflation in January Is Higher than Expected

Image generated by GTP-4o illustrating inflation

On February 12, the Bureau of Labor Statistics (BLS) released its monthly report on the consumer price index (CPI). The following figure compares headline inflation (the blue line) and core inflation (the dotted green line).

  • The headline inflation rate, which is measured by the percentage change in the CPI from the same month in the previous month, was 3.0 percent in January—up from 2.9 percent in December. 
  • The core inflation rate, which excludes the prices of food and energy, was 3.3 percent in January—up from 3.2 percent in December. 

Headline inflation and core inflation were both above 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) jumped from 4.5 percent in December to 5.7 percent in January—following a large jump in inflation from November to December. Core inflation (the dotted green line) more than doubled from 2.5 percent in December to 5.5 percent in January.

Overall, considering 1-month and 12-month inflation together, today’s data are concerning. One-month headline inflation is the highest it’s been since August 2023. One-month core inflation is the highest it’s been since April 2023. This month’s CPI report reinforces the conclusion from other recent inflation reports that progress on lowering inflation appears to have stalled. So, the probability of a “no landing” outcome, with inflation remaining above the Fed’s target for an indefinite period, seems to have increased. 

Of course, it’s important not to overinterpret the data from a single month. The figure shows that 1-month inflation 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.

As we’ve discussed in previous blog posts, Federal Reserve Chair Jerome Powell and his colleagues on the Fed’s policymaking Federal Open Market Committee (FOMC) have been closely following inflation in the price of shelter. The price of “shelter” in the CPI, as explained here, includes both rent paid for an apartment or a house and “owners’ equivalent rent of residences (OER),” which is an estimate of what a house (or apartment) would rent for if the owner were renting it out. OER is included in the CPI to account for the value of the services an owner receives from living in an apartment or house.

As the following figure shows, inflation in the price of shelter has been a significant contributor to headline inflation. The blue line shows 12-month inflation in shelter, and the green line shows 1-month inflation in shelter. Twelve-month inflation in shelter has been declining since the spring of 2023, but in January it was still relatively high at 4.4 percent. One-month inflation in shelter—which is much more volatile than 12-month inflation in shelter—rose sharply from 3.3 percent in December to 4.6 percent in January. Clearly a worrying sign given that many economists were expecting that shelter inflation would continue to slow.

To better estimate of 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 at 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) jumped from 3.1 percent in December to 5.2 percent in January. Median inflation (the green line), which had been stable over the past five months, increased from 3.2 percent in December to 3.9 percent in January.

The following figure shows 1-month median and trimmed-mean inflation. One-month trimmed-mean inflation jumped from 3.1 percent in December to 5.1 percent in January. One-month median inflation rose from 3.2 percent in December to 3.9 percent in January. These data provide confirmation that (1) CPI inflation at this point is running higher than a rate that would be consistent with the Fed achieving its inflation target, and (2) that progress toward the target has slowed.

Looking at the futures market for federal funds, investors who buy and sell federal funds futures contracts are not expecting that the Fed’s policymaking Federal Open Market Committee (FOMC) will cut its target for the federal funds until this fall. (We discuss the futures market for federal funds in this blog post.) Investors assign a higher probability to the FOMC leaving its target range for the federal funds rate unchanged at 4.25 percent to 4.50 percent at its January, March, June, July, and September meetings. It’s not until the FOMC’s meeting on October 28-29 that, as shown below, investors assign a higher probability to a rate cut than to the committee leaving the rate unchanged.

Headline CPI Inflation Is Higher in December but Core Inflation Is Lower than Expected

On January 15, the Bureau of Labor Statistics (BLS) released its monthly report  on the consumer price index (CPI). The following figure compares headline inflation (the blue line) and core inflation (the green line).

  • The headline inflation rate, which is measured by the percentage change in the CPI from the same month in the previous month, was 2.9 percent in December—up from 2.7 percent in November. 
  • The core inflation rate, which excludes the prices of food and energy, was 3.2 percent in December—down from 3.3 percent in November. 

Headline inflation was slightly above and core inflation was slightly below 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) jumped from 3.8 percent in November to 4.8 percent in December. Core inflation (the green line) decreased from 3.8 percent in November to 2.7 percent in December.

Overall, considering 1-month and 12-month inflation together, the most favorable news is the low value of the 1-month core inflation rate. The most concerning news is a sharp increase in 1-month headline inflation, which brought that measure to its highest reading since February 2024. On balance, this month’s CPI report doesn’t do much to challenge the conclusion of other recent inflation reports that progress on lowering inflation has slowed or, possibly, stalled. So, the probability of a “no landing” outcome, with inflation remaining above the Fed’s target for an indefinite period, seems to have at least slightly increased. 

Of course, it’s important not to overinterpret the data from a single month. The figure shows that 1-month inflation 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.

As we’ve discussed in previous blog posts, Federal Reserve Chair Jerome Powell and his colleagues on the Fed’s policymaking Federal Open Market Committee (FOMC) have been closely following inflation in the price of shelter. The price of “shelter” in the CPI, as explained here, includes both rent paid for an apartment or a house and “owners’ equivalent rent of residences (OER),” which is an estimate of what a house (or apartment) would rent for if the owner were renting it out. OER is included in the CPI to account for the value of the services an owner receives from living in an apartment or house.

As the following figure shows, inflation in the price of shelter has been a significant contributor to headline inflation. The blue line shows 12-month inflation in shelter, and the red line shows 1-month inflation in shelter. Twelve-month inflation in shelter has been declining since the spring of 2023, but in December it was still high at 4.6 percent. One-month inflation in shelter—which is much more volatile than 12-month inflation in shelter—fell from 4.1 percent in November to 3.1 percent in December.

To better estimate of 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 median inflation (the red line) declined slightly from 3.9 percent in November to 3.8 percent in December. Twelve-month trimmed mean inflation (the blue line) was unchanged at 3.2 percent for the fifth month in a row.

The following figure shows 1-month median and trimmed mean inflation. One-month median inflation rose from 2.8 percent in November to 3.6 percent in December. One-month trimmed mean inflation fell slightly from 3.3 percent in November to 3.2 percent in December. These data provide confirmation that (1) CPI inflation at this point is likely running higher than a rate that would be consistent with the Fed achieving its inflation target, and (2) that progress toward the target has slowed.

What are the implications of this CPI report for the actions the FOMC may take at its next meeting on January 28-29? The stock market rendered a quick verdict, as the following figure from the Wall Street Journal shows. As soon as the market opened on Wednesday morning, all three of the most widely followed stock market indexes jumped—as indicated by the vertical segments in the figure. Investors seem to be focusing on core CPI inflation being lower than expected, which should increase the probability that the FOMC will cut its target for the federal funds rate at either its March or May meeting. Lower inflation and lower interest rates would be good news for stock prices.

Investors who buy and sell federal funds futures contracts still do not expect that the FOMC will cut its target for the federal funds rate at its next meeting, as indicated by the following figure. (We discuss the futures market for federal funds in this blog post.) Today, investors assign a probability of 93.7 percent to the FOMC leaving its target range for the federal funds rate unchanged at 4.25 percent to 4.50 percent at its January 28-29 meeting, and a probability of only 2.7 percent to the committee cutting its target range by 0.25 percentage point (25 basis points).

As Expected, CPI Inflation Is Higher in November as the Fed Struggles to Hit Its Inflation Target.

On December 11, the Bureau of Labor Statistics (BLS) released its monthly report on the consumer price index (CPI). The following figure compares headline inflation (the blue line) and core 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 month, was 2.7 percent—up from 2.6 percent in October. 
  • The core inflation rate, which excludes the prices of food and energy, was unchanged at 3.3 percent for the fourth month in a row. 

Both headline inflation and core inflation were the same as economists surveyed by the Wall Street Journal 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) increased sharply from 3.0 percent in October to 3.8 percent in November. Core inflation (the red line) increased from 3.4 percent in October to 3.8 percent in November.

Overall, considering 1-month and 12-month inflation together, the U.S. economy may still be on course for a soft landing—with the annual inflation rate returning to the Fed’s 2 percent target without the economy being pushed into a recession. However, progress on lowering inflation has slowed or, possibly, stalled. So, the probability of a “no landing” outcome, with inflation remaining above the Fed’s target for an indefinite period, seems to have increased.

The relatively high rates of core inflation in both the 12-month and 1-month measures are concerning because most economists believe that core inflation is a better indicator of the underlying inflation rate than is headline inflation. It’s important not to overinterpret the data from a single month, although this is the fourth month in a row that core inflation has been above 3 percent. (Note, that the Fed uses the personal consumption expenditures (PCE) price index, rather than the CPI in evaluating whether it is hitting its 2 percent inflation target.)

As we’ve discussed in previous blog posts, Federal Reserve Chair Jerome Powell and his colleagues on the Fed’s policymaking Federal Open Market Committee (FOMC) have been closely following inflation in the price of shelter.

As the following figure shows, inflation in the price of shelter has been a significant contributor to headline inflation. The blue line shows 12-month inflation in shelter, and the red line shows 1-month inflation in shelter. Twelve-month inflation in shelter has been declining since the spring of 2023, but in November it was at a still high 4.8 percent. One-month inflation in shelter—which is much more volatile than 12-month inflation in shelter—fell from 4.7 percent in October to 4.1 percent in November.

To better estimate of 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 good and services with the highest inflation rates and the 8 percent of goods and services with the lowest inflation rates. 

The following figure is from the Federal Reserve Bank of Cleveland. It shows that median inflation (the orange line) fell from 4.1 percent in October to 3.9 percent in November. Trimmed mean inflation (the blue line) was unchanged at 3.2 percent for the fourth month in a row. These data provide confirmation that (1) core CPI inflation at this point is likely running higher than a rate that would be consistent with the Fed achieving its inflation target, and (2) that progress toward the target has slowed.

Will this persistence in inflation above the Fed’s 2 percent target cause the FOMC to hold constant its target range for the federal funds rate? Investors who buy and sell federal funds futures contracts still expect that the FOMC will cut its target for the federal funds rate by 0.25 percentage point at its next meeting on December 17-18. (We discuss the futures market for federal funds in this blog post.) The following figure shows that today these investors assign a probability of 94.7 percent to the FOMC cutting its target for the federal funds rate by 0.25 percentage point and a probability of only 5.3 percent to the committee leaving its target unchanged at its current range of 4.50 percent to 4.75 percent.

Latest CPI Report Indicates That the Fed May Have Trouble Guiding the Economy the Last 1,000 Feet to a Soft Landing

On November 13, the Bureau of Labor Statistics (BLS) released its monthly report on the consumer price index (CPI). The following figure compares headline inflation (the blue line) and core 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 month, was 2.6 percent—up from 2.4 percent in September. 
  • The core inflation rate, which excludes the prices of food and energy, was unchanged at 3.3 percent for the third month in a row. 

Both headline inflation and core inflation were the values that economists surveyed by the Wall Street Journal 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) increased from 2.2 percent in September to 3.0 percent in October. Core inflation (the red line) fell from 3.8 percent in September to 3.4 percent in October.

Overall, considering 1-month and 12-month inflation together, the U.S. economy may still be on course for a soft landing—with the annual inflation rate returning to the Fed’s 2 percent target without the economy being pushed into a recession. However, progress on lowering inflation may have slowed or, possibly, stalled. The relatively high rates of core inflation in both the 12-month and 1-month measures are concerning because most economists believe that core inflation is a better indicator of the underlying inflation rate than is headline inflation. It’s important not to overinterpret the data from a single month, although this is the third month in a row that core inflation has been above 3 percent. (Note, that the Fed uses the personal consumption expenditures (PCE) price index, rather than the CPI in evaluating whether it is hitting its 2 percent inflation target.)

As we’ve discussed in previous blog posts, Federal Reserve Chair Jerome Powell and his colleagues on the Fed’s policymaking Federal Open Market Committee (FOMC) have been closely following inflation in the price of shelter. The price of “shelter” in the CPI, as explained here, includes both rent paid for an apartment or house and “owners’ equivalent rent of residences (OER),” which is an estimate of what a house (or apartment) would rent for if the owner were renting it out. OER is included in the CPI to account for the value of the services an owner receives from living in an apartment or house.

As the following figure shows, inflation in the price of shelter has been a significant contributor to headline inflation. The blue line shows 12-month inflation in shelter, and the red line shows 1-month inflation in shelter. Twelve-month inflation in shelter has been declining since the spring of 2023, but increased in October to 4.9 percent from 4.8 percent in September. One-month inflation in shelter—which is much more volatile than 12-month inflation in shelter—increased sharply from 2.7 percent in September to 4.7 percent in October.

Chair Powell and the other members of the FOMC have been expecting that the inflation in shelter would continue to decline. For instance, in his press conference following the last FOMC meeting on November 7, Powell stated that:

“What’s going on there is, you know, market rents, newly signed leases, are experiencing very low inflation. And what’s happening is older—you know, leases that are turning over are taking several years to catch up to where market leases are; market rent leases are. So that’s just a catch-up problem. It’s not really reflecting current inflationary pressures, it’s reflecting past inflationary pressures.”

The recent uptick in shelter inflation may concern FOMC members as they consider whether, and by how much, to cut their target for the federal funds rate at their next meeting on December 17-18. Bear in mind, though, that shelter has a weight of only 15 percent in the PCE price index that the Fed uses to gauge whether it is hitting its 2 percent inflation target in contrast with the 33 percent weight that shelter has in the CPI.

To better estimate of 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 good and services with the highest inflation rates and the 8 percent of goods and services with the lowest inflation rates. 

The following figure is from the Federal Reserve Bank of Cleveland. It shows that median inflation (the orange line) was unchanged in October at 4.1 percent. Trimmed mean inflation (the blue line) was also unchanged at 3.2 percent. These data provide confirmation that (1) core CPI inflation at this point is likely running at least slightly higher than a rate that would be consistent with the Fed achieving its inflation target and (2) that progress toward the target has slowed.

Will this persistence in inflation above the Fed’s 2 percent target cause the FOMC to hold constant its target range for the federal funds rate? Investors who buy and sell federal funds futures contracts expect that the FOMC will cut still cut its target for the federal funds rate by 0.25 percentage point at its December meeting. (We discuss the futures market for federal funds in this blog post.) The following figure that today these investors assign a probability of 75.7 percent to the FOMC cutting its target for the federal funds rate by 0.25 percentage point and a probability of 24.3 percent to the committee leaving its target unchanged at a range of 4.50 percent to 4.75 percent.



CPI Inflation Running Slightly Higher than Expected

Image illustrating inflation generated by GTP-4o.

This morning (October 10), the Bureau of Labor Statistics (BLS) released its monthly report on the consumer price index (CPI). As the following figure shows, the inflation rate for September measured by the percentage change in the CPI from the same month in the previous month—headline inflation (the blue line)—was 2.4 percent down from 2.6 percent in August. That was the lowest headline inflation rate since February 2021. Core inflation (the red line)—which excludes the prices of food and energy—was unchanged at 3.3 prcent. Both headline inflation and core inflation were slightly higher than economists surveyed by the Wall Street Journal had expected.  

As the following figure shows, if 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—we see that headline inflation (the blue line) decreased from 2.3 percent in August to 2.2 percent in September. Core inflation (the red line) increased from 3.4 percent in August to 3.8 percent in September.

Overall, we can say that, taking 1-month and 12 month inflation together, the U.S. economy may still be on course for a soft landing—with the annual inflation rate returning to the Fed’s 2 percent target without the economy being pushed into a recession—but the increase in 1-month core inflation is concerning because most economists believe that core inflation is a better indicator of the underlying inflation rate than is headline inflation. Of course, as always, it’s important not to overinterpret the data from a single month, although this is the second month in a row that core inflation has been well above 3 percent. (Note, also, that the Fed uses the personal consumption expenditures (PCE) price index, rather than the CPI in evaluating whether it is hitting its 2 percent inflation target.)

As we’ve discussed in previous blog posts, Federal Reserve Chair Jerome Powell and his colleagues on the FOMC have been closely following inflation in the price of shelter. The price of “shelter” in the CPI, as explained here, includes both rent paid for an apartment or house and “owners’ equivalent rent of residences (OER),” which is an estimate of what a house (or apartment) would rent for if the owner were renting it out. OER is included to account for the value of the services an owner receives from living in an apartment or house.

As the following figure shows, inflation in the price of shelter has been a significant contributor to headline inflation. The blue line shows 12-month inflation in shelter and the red line shows 1-month inflation in shelter. After rising in August, 12-month inflation in shelter resumed the decline that began in the spring of 2023, falling from 5.2 percent in August to 4.8 percent September. One-month inflation in shelter—which is much more volatile than 12-month inflation in shelter—declined sharply from 6.4 percent in August to 2.7 percent in September. The members of the FOMC are likely to find the decline in inflation in shelter reassuring as they consider another cut to the target for the federal funds rate at the committee’s next meeting on November 6-7. Shelter has a smaller weight of 15 percent in the PCE price index that the Fed uses to gauge whether it is hitting its 2 percent inflation target in contrast with the 33 percent weight that shelter has in the CPI.

Finally, in order to get a better estimate of 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 good and services with the higherst inflation rates and the 8 percent of goods and services with the lowest inflation rates. 

As the following figure (from the Federal Reserve Bank of Cleveland) shows, median inflation (the orange line) declined slightly from 4.2 percent in August to 4.1 percent in September. Trimmed mean inflation (the blue line) was unchanged at 3.2 percent. These data provide confirmation that core CPI inflation at this point is likely running at least slightly higher than a rate that would be consistent with the Fed achieving its inflation target.

The FOMC cut its target for the federal funds rate by 0.50 percentage point (50 basis points) from 5.50 percent to 5.25 percent to 5.00 percent to 4.75 percent at its last meeting on September 17-18. Some economists and investors believed that the FOMC might cut its target by another 50 basis points at its next meeting on November 6-7. This inflation report makes that outcome less likely. In addition, the release of the minutes from the September 17-18 meeting revealed that a significant number of committee members may have preferred a 25 basis point cut rather than a 50 basis point cut at that meeting:

“However, noting that inflation was still somewhat elevated while economic growth remained solid and unemployment remained low, some participants observed that they would have preferred a 25 basis point reduction of the target range at this meeting, and a few others indicated that they could have supported such a decision.”

Investors who buy and sell federal funds futures contracts expect that the FOMC will cut its target for the federal funds rate by 0.25 percentage point at its November meeting. (We discuss the futures market for federal funds in this blog post.) As shown in the following figure, today these investors assign a probability of 80.3 percent to the FOMC cutting its target for the federal funds rate by 0.25 percentage point and a probability of 19.7 percent to the committee leaving its target unchanged.

Mixed CPI Inflation Report Sets the Stage for Fed Rate Cut

Image illustrating inflation generated by GTP-4o.

Today (September 11), the Bureau of Labor Statistics (BLS) released its monthly report on the consumer price index (CPI). This report is the last one that will be released before the Fed’s policy-making Federal Open Market Committee (FOMC) holds its next meeting on September 17-18.

As the following figure shows, the inflation rate for August measured by the percentage change in the CPI from the same month in the previous month—headline inflation (the blue line)—was 2.6 percent down from 2.9 percent in July. Core inflation (the red line)—which excludes the prices of food and energy—increased slightly to 3.3 percent in August from 3.2 percent in July. Headline inflation was slightly below what economists surveyed by the Wall Street Journal had expected, while core inflation was slightly higher.

As the following figure shows, if 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—we see that both headline and core inflation increased. Headline inflation (the blue line) increased from 1.8 percent in July to 2.3 percent in August. Core inflation (the red line) jumped from 2.0 percent in July to 3.4 percent in August. Overall, we can say that, taking 1-month and 12 month inflation together, the U.S. economy may still be on course for a soft landing—with the annual inflation rate returning to the Fed’s 2 percent target without the economy being pushed into a recession—but the increase in 1-month inflation is concerning. Of course, as always, it’s important not to overinterpret the data from a single month. (Note, also, that the Fed uses the personal consumption expenditures (PCE) price index, rather than the CPI in evaluating whether it is hitting its 2 percent inflation target.)

As we’ve discussed in previous blog posts, Federal Reserve Chair Jerome Powell and his colleagues on the FOMC have been closely following inflation in the price of shelter. The price of “shelter” in the CPI, as explained here, includes both rent paid for an apartment or house and “owners’ equivalent rent of residences (OER),” which is an estimate of what a house (or apartment) would rent for if the owner were renting it out. OER is included to account for the value of the services an owner receives from living in an apartment or house.

As the following figure shows, inflation in the price of shelter has been a significant contributor to headline inflation. The blue line shows 12-month inflation in shelter and the red line shows 1-month inflation in shelter. Twelve-month inflation in shelter reversed the decline that began in the spring of 2023, rising from 5.0 percent in July to 5.2 percent August. One-month inflation in shelter—which is much more volatile than 12-month inflation in shelter—increased from 4.6 percent in July to 5.2 percent in August, continuing an increase that began in June. The increase in 1-month inflation in shelter may concern the members of the FOMC, as may, to a lesser extent, the increase in 12-month inflation in shelter. Shelter has a smaller weight of 15 percent in the PCE price index that the Fed uses to gauge whether it is hitting its 2 percent inflation target in contrast with the 33 percent weight that shelter has in the CPI. But persistent shelter inflation in the 5 percent range would make a soft landing more difficult.

Finally, in order to get a better estimate of 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 good and services with the higherst inflation rates and the 8 percent of goods and services with the lowest inflation rates. 

As the following figure (from the Federal Reserve Bank of Cleveland) shows, median inflation (the orange line) declined slightly from 4.3 percent in July to 4.2 percent in August. Trimmed mean inflation (the blue line) also declined slightly from 3.3 in July to 3.2 percent in August. These data provide confirmation that core CPI inflation is likely running higher than a rate that would be consistent with the Fed achieving its inflation target.

For the past few weeks Fed officials have been indicating that the FOMC is likely to cut its target for the federal funds at its next meeting on Septembe 17-18. Investors who buy and sell federal funds futures contracts expect that the FOMC will cut its target for the federal funds rate by 0.25 percentage point from the current range of 5.50 percent to 5.25 percent. (We discuss the futures market for federal funds in this blog post.) As shown in the following figure, today these investors assign a probability of 85.0 percent to the FOMC cutting its target for the federal funds rate by 0.25 percentage point at its next meeting and a probability of only 15.0 percent that the cut will be 0.50 percentage point.

The FOMC has to balance the risk of leaving its target for the federal funds rate at its current level for too long—increasing the risk of slowing demand so much that the economy slips into recession—against the risk of cutting its target too soon—increasing the risk that inflation persists above the Fed’s 2 percent target. We’ll see at the committee’s next meeting how Fed Chair Jerome Powell and the other members assess the current state of the economy as they consider when and by how much to cut their target for the federal funds rate.

Latest CPI Report Shows Inflation Continuing to Slow

In testifying before Congress this week, Federal Reserve Chair Jerome Powell indicated that the Fed’s policy-making Federal Open Market Committee (FOMC) was becoming more concerned that it not be too late in reducing its target for the federal funds rate:

“[I]n light of the progress made both in lowering inflation and in cooling the labor market over the past two years, elevated inflation is not the only risk we face. Reducing policy restraint too late or too little could unduly weaken economic activity and employment.”

Powell also noted that: “more good data would strengthen our confidence that inflation is moving sustainably toward 2 percent.” Today (July 11), Powell received more good data as the Bureau of Labor Statistics (BLS) released its monthly report on the consumer price index (CPI), which showed a further slowing in inflation.

As the following figure shows, the inflation rate for June measured by the percentage change in the CPI from the same month in the previous month—headline inflation (the blue line)—was 3.o percent down from 3.3 percent in May. Core inflation (the red line)—which excludes the prices of food and energy—was 3.3 percent in June, down from 3.4 percent in May.

As the following figure shows, if 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—the declines in the inflation rate are much larger. Headline inflation (the blue line) declined from 0.1 percent in May to –0.7 in June—consumer prices fell during June. Core inflation (the red line) declined from 2.0 percent in May to 0.8 percent in June. Overall, we can say that inflation has cooled further in June, bringing the U.S. economy closer to a soft landing—with the annual inflation rate returning to the Fed’s 2 percent target without the economy being pushed into a recession.  (Note, though, that the Fed uses the personal consumption expenditures (PCE) price index, rather than the CPI in evaluating whether it is hitting its 2 percent inflation target.)

The FOMC has been looking closely at inflation in the price of shelter. The price of “shelter” in the CPI, as explained here, includes both rent paid for an apartment or house and “owners’ equivalent rent of residences (OER),” which is an estimate of what a house (or apartment) would rent for if the owner were renting it out. OER is included to account for the value of the services an owner receives from living in an apartment or house.

As the following figure shows, inflation in the price of shelter has been a significant contributor to headline inflation. The blue line shows 12-month inflation in shelter and the red line shows 1-month inflation in shelter. Twelve-month inflation in shelter continued its decline that began in the spring of 2023. One-month inflation in shelter declined substantially from 4.9 percent in May to 2.1 percent in June. These values indicate that the price of shelter may no longer be a significant driver of headline inflation.

Finally, in order to get a better estimate of the underlying trend in inflation, some economists look at median inflation and trimmed mean inflation. Meadin 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 good and services with the higherst inflation rates and the 8 percent of goods and services with the lowest inflation rates.

As the following figure (from the Federal Reserve Bank of Cleveland) shows, both median inflation (the brown line) and trimmed mean inflation (the blue line) were somewhat higher than either headline CPI inflation or core CPI inflation. One conclusion from these data is that headline and core inflation may be somewhat understating the underlying rate of inflation.

Financial markets are interpreting the most inflation and employment data as indicating that at its meeting on Septembe 17-18 the FOMC is likely to cut its target range for the federal funds rate from the current 5.25 percent to 5.50 to 5.00 percent to 5.25 percent.

Futures markets allow investors to buy and sell futures contracts on commodities–such as wheat and oil–and on financial assets. Investors can use futures contracts both to hedge against risk—such as a sudden increase in oil prices or in interest rates—and to speculate by, in effect, betting on whether the price of a commodity or financial asset is likely to rise or fall. (We discuss the mechanics of futures markets in Chapter 7, Section 7.3 of Money, Banking, and the Financial System.) The CME Group was formed from several futures markets, including the Chicago Mercantile Exchange, and allows investors to trade federal funds futures contracts. The data that result from trading on the CME indicate what investors in financial markets expect future values of the federal funds rate to be. The following chart from the CME’s FedWatch Tool shows the current values from trading of federal funds futures.

The probabilities in the chart reflect investors’ predictions of what the FOMC’s target for the federal funds rate will be after the committee’s September meeting. The chart indicates that investors assign a probability of only 8.1 percent to the FOMC leaving its federal funds rate target unchanged at its September meeting, but a 84.6 percent probability of the committee cutting its target by 0.25 percentage point (and a 7.3 percent probability of the committee cutting its target by 0.50 percent age point).
