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).

Latest PCE Report Shows Inflation Slowing

On Friday, June 28, the Bureau of Economic Analysis (BEA) released its “Personal Income and Outlays” report for April, which includes monthly data on the personal consumption expenditures (PCE) price index. Inflation as measured by annual changes in the consumer price index (CPI) receives the most attention in the media, but the Federal Reserve looks instead to inflation as measured by 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 (blue line) and core PCE inflation (red line)—which excludes energy and food prices—for the period since January 2015 with inflation measured as the change in the PCE from the same month in the previous year. Measured this way, in May PCE inflation (the blue line) was 2.6 percent in May, down slightly from PCE inflation of 2.7 percent in April. Core PCE inflation (the red line) in May was also 2.6 percent, down from 2.8 percent in April.

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 sharply declined from 3.2 percent in April to -0.1 percent in in May—meaning that consumer prices actually fell during May. Core PCE inflation declined from 3.2 percent in April to 1.0 percent in May.  This decline indicates that inflation by either meansure slowed substantially in May, but data for a single month should be interpreted with caution.

The following figure shows another way of gauging inflation by including the 12-month inflation rate in the PCE (the same as shown in the figure above—although note that PCE inflation is now the red line rather than the blue line), inflation as measured using only the prices of the services included in the PCE (the green line), and the trimmed mean rate of PCE inflation (the blue line). Fed Chair Jerome Powell and other members of the Federal Open Market Committee (FOMC) have said that they are concerned by the persistence of elevated rates of inflation in services. The trimmed mean measure is compiled by economists at the Federal Reserve Bank of Dallas by dropping from the PCE the goods and services that have the highest and lowest rates of inflation. It can be thought of as another way of looking at core inflation by excluding the prices of goods and services that had particularly high or particularly low rates of inflation during the month.

Inflation using the trimmed mean measure was 2.8 percent in May (calculated as a 12-month inflation rate), down only slightly from 2.9 percent in April—and still well above the Fed’s target inflation rate of 2 percent. Inflation in services remained high in May at 3.9 percent, down only slightly from 4.0 percent in April.

This month’s PCE inflation data indicate that the inflation rate is still declining towards the Fed’s target, with the low 1-month inflation rates being particularly encouraging. But the FOMC will likely need additional data before deciding to lower the committee’s target for the federal funds rate, which is currently 5.25 percent to 5.50 percent. The next meeting of the FOMC is July 30-31. What do financial markets think the FOMC will decide at that meeting?

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 July meeting. The chart indicates that investors assign a probability of only 10.3 percent to the FOMC cutting its federal funds rate target by 0.25 percentage point at that meeting and an 89.7 percent probability of the commitee leaving the target unchanged.

In contrast, the following figure shows that investors expect that the FOMC will cut its federal funds rate at the meeting scheduled for September 17-18. Investors assign a 57.9 percent probability of a 0.25 percentage point cut and a 6.2 percent probability of a 0.50 percentage point cut. The committee deciding to leave the target unchanged at 5.25 percent to 5.50 percent is assigned a probability of only 35.9 percent.
