A Double Dose of Bad Inflation News

This morning, the Bureau of Labor Statistics (BLS) released its report on the consumer price index (CPI) for March. Yesterday,  the Bureau of Economic Analysis (BEA) released monthly data on the personal consumption expenditures (PCE) price index for February as part of its “Personal Income and Outlays” report.  Both reports showed that the inflation has worsened. Note that data for the PCE were collected before the beginning of the conflict with Iran.

CPI Inflation jumped to a level well above the Federal Reserve’s 2 percent annual inflation target. The following figure compares headline CPI inflation (the blue line) and core CPI inflation (the red line). Because of the effects of the federal government shutdown, the BLS didn’t report inflation rates for October or November, so both lines show gaps for those months.  

  • The headline inflation rate, which is measured by the percentage change in the CPI from the same month in the previous year, was 3.3 percent in March, up from 2.4 percent in February. 
  • The core inflation rate, which excludes the prices of food and energy, was 2.6 percent in March, up only slightly from 2.5 percent in February. 

Headline inflation was equal to the forecast of economists surveyed by the Wall Street Journal but well below the 3.7 percent rate forecast by economists surveyed by FactSet. Core inflation was slightly below the forecast of 2.7 percent in both surveys. Higher energy prices drove the jump in CPI inflation.

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) was 10.9 percent in March, up from 3.2 percent in February. Core inflation (the red line) actually decreased to 2.4 in March from 2.6 percent in February.

The following figure emphasizes the role paid by energy prices in causing the jump in inflation. The blue line shows the 1-month inflation rate in all energy prices included in the CPI. The red line shows the 1-month inflation rate in gasoline prices—which was an astounding 907.4 percent.

Did the jump in energy prices pass through to increases in food prices, which are a key concern for many consumers? The following figure shows 1-month inflation in the CPI category “food at home” (the blue bar)—primarily food purchased at grocery stores—and the category “food away from home” (the red bar)—primarily food purchased at restaurants. Inflation in both measures fell in March, indicating that they hadn’t (yet?) been affected by rising energy prices. Food at home actually decreased by 1.9 percent in March after increasing by 5.4 percent in February. Food away from home increased 2.9 percent in March, down from 3.9 percent in February.

Turning now to PCE inflation for February. The following figure shows headline PCE inflation (the blue line) and core PCE inflation (the red line)—which excludes energy and food prices—with inflation measured as the percentage change in the PCE from the same month in the previous year. Headline PCE inflation was 2.8 percent in February, unchanged from January. Core PCE inflation was 3.0 percent in February, down slight from 3.1 percent in January . Headline inflation was slightly higher and core inflation was equal to the forecast of economists surveyed by FactSet.

The following figure shows 1-month headline PCE inflation and core PCE. Measured this way, headline PCE inflation increased from 3.7 percent in January to 4.6 percent in February. Core PCE inflation declined from 4.8 percent in January to 4.5 percent in February. So, even before the effects of the escalation in energy prices, both 1-month and 12-month PCE inflation are telling the same story of inflation above the Fed’s target—well above in the case of 1-month inflation. These numbers raise significant concern about whether inflation was making progress toward the Fed’s 2 percent target even before the effects of the rise in energy prices.

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 rise, the prices of financial services included in the PCE price index also rise. 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 2.7 percent in February, up slightly from 2.6 percent in January. Core market-based PCE inflation was 2.9 percent in February, up slightly from 2.8 percent in January. So, both market-based measures show inflation as stable but well 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 increased to 2.1 percent in November from 1.3 percent in October. One-month core market-based inflation fell to 1.3 percent in November from 2.0 percent in October. So, in November, 1-month market-based inflation was at or below the Fed’s annual inflation target. 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.

What effect are these troubling inflation reports likely to have on the Fed’s policymaking Federal Open Market Committee (FOMC) at its next meeting on April 28–29—likely Jerome Powell’s last meeting as Fed chair? Economists generally recommend that central banks “look through”—that is, take no action—in response to a supply shock. A supply shock ordinarily results in a one-time increase in the price level, rather than a long-lasting increase in inflation. Fed policymakers, though, are aware that inflation has been running above their 2 percent target for more than five years. The possibility that even a temporary spike in inflation might result in a significant increase in the inflation rate that households and firms expect is a concern. At this point, investors in the federal funds futures market assign only a very small probability to the FOMC raising or lowering its target for the federal funds rate at the next several meetings. Following the next meeting, Powell will give his thoughts on these and other issues at a press conference.

CPI Inflation Comes in about as Expected

The news this morning on inflation was ho-hum. The Bureau of Labor Statistics (BLS) released its report on the consumer price index (CPI) for February. Inflation was about as expected and remained moderately above the Federal Reserve’s 2 percent annual inflation target. The following figure compares headline CPI inflation (the blue line) and core CPI inflation (the red line). Because of the effects of the federal government shutdown, the BLS didn’t report inflation rates for October or November, so both lines show gaps for those months.  

  • The headline inflation rate, which is measured by the percentage change in the CPI from the same month in the previous year, was 2.4 percent in February, unchanged from January. 
  • The core inflation rate, which excludes the prices of food and energy, was 2.5 percent in February, also unchanged from January. 

Headline and core inflation were both equal to the forecasts of economists surveyed by the Wall Street Journal.

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) was 3.2 percent in February, up from 2.1 percent in January. Core inflation (the red line) decreased to 2.6 percent in February from 3.6 percent in January.

The 1-month and 12-month headline and core inflation rates are telling similar stories, with both measures indicating that the rate of price increase is running somewhat above the Fed’s 2 percent inflation target.  

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. February data on the PCE will be released on Friday.

In recent months, there have been many media reports on how consumers are concerned about declining affordability. Affordability has no exact interpretation but typically means concern about inflation in goods and services that consumers buy frequently. 

Many consumers seem worried about inflation in food prices. The following figure shows 1-month inflation in the CPI category “food at home” (the blue bar)—primarily food purchased at groceries stores—and the category “food away from home” (the red bar)—primarily food purchased at restaurants. Inflation in both measures rose in February. Food at home increased 5.4 percent in February, up from 2.3 percent in January. Food away from home increased 3.9 percent in February, up from 1.8 percent in January. Again, 1-month inflation rates can be volatile.

Gasoline prices, which bounce around a lot from month to month, were up in February. The following figure shows 1-month inflation in gasoline prices. In February the price of gasoline increase at an annual rate of 10.1 percent, after having fallen at an annual rate of 32.2 percent in January. These data were gathered before the increase in gasoline prices caused by the conflict in Iran. The increase in food and gasoline prices helped push headline inflation above core inflation in February.

The affordability discussion has also focused on the cost of housing. 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. The following figure shows 1-month inflation in shelter. 

One-month inflation in shelter, which has been trending down since early 2023, increased slightly to 2.8 percent in February from 2.7 in January.

It’s unlikely that this inflation report will have much effect on the views of the members of the Federal Reserve’s policymaking Federal Open Market Committee (FOMC). The FOMC is unlikely to lower its target for the federal funds rate at its next meeting on March 17–18. The probability that investors in the federal funds futures market assign to the FOMC keeping its target rate unchanged at that meeting increased only slightly from 98.4 percent yesterday to 99.4 percent this afternoon.

CPI Inflation Slows but Some Data Are Missing from Latest Report

On Thursday (December 18) the Bureau of Labor Statistics (BLS) released its latest report on the consumer price index (CPI). The federal government shutdown, which lasted from October 1 to November 12, is still affecting the macroeconomic statistics being gathered by the BLS and other agencies. The BLS notes in the report:

“BLS did not collect survey data for October 2025 due to a lapse in appropriations. BLS was unable to retroactively collect these data. For a few indexes, BLS uses nonsurvey data sources instead of survey data to make the index calculations. BLS was able to retroactively acquire most of the nonsurvey data for October. CPI data collection resumed on November 14, 2025.”

The following table from the CPI report gives an indication of how much data that is normally collected wasn’t collected in October or November.

Bearing in mind the missing data, the following figure compares headline CPI inflation (the blue bar) and core CPI inflation (the red bar) as reported in this month’s CPI report.

  • 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 November, down from 3.0 in September. 
  • The core inflation rate, which excludes the prices of food and energy, was 2.6 percent in November, down from 3.0 percent in September. 

Economists who were surveyed by Fact Set had forecast that both headline inflation and core inflation would rise to 3.1 percent in November. Economists surveyed by the Wall Street Journal also forecast that headline inflation would rise to 3.1 percent in November, but forecast that core inflation would rise slightly less to 3.0 percent. It’s unclear whether the economists were aware at the time they were surveyed how much data for October and November would be missing from this month’s report.

Because of how much data that is normally collected was missing from the calculations of November’s inflation rate, the results should be treated with caution. The Wall Street Journal quoted an economist at the investment bank UBS as advising: “I think you largely just put this one to the side. Maybe this report gives a minor downward sign for overall inflation, but the vast, vast majority of this is just noise and should be ignored.”

Several economists were concerned about the computation the BLS had to make to deal with the lack of direct data on 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. The following figure shows CPI inflation, measured as the percentage change since the same month in the previous year, leaving out the price of shelter. Measured this way, inflation was 2.6 percent in November, which is slightly lower than the 2.7 percent inflation rate the BLS reported when including all items.

What effect have the tariffs that the Trump administration announced on April 2 had on inflation? (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 November, inflation in durable goods decreased to 1.8 percent from 2.2 percent in September. Inflation in services in November was 3.2 percent, down from 3.6 percent in September. So the upward pressure on goods prices from the tariffs seems to be declining. But, again, missing data makes it’s unclear to what extent November inflation numbers are representative of what’s actually happening currently to prices.

It’s unlikely that this inflation report will have much effect on the views of the members of the Federal Reserve’s policymaking Federal Open Market Committee. In a press conference after the committee’s most recent meeting, Fed Chair Jerome Powell cautioned against drawing firm conclusions from data for October and November:

“I should mention on the data, as long as I’m talking about it, that we’re going to need to be careful in assessing particularly the household survey data. There are very technical reasons about the way data are collected in some of these measures, both in, you know, inflation and in labor—in the  labor market so that the data may be distorted. And not just sort of more volatile, but distorted. And that—it’s—and  that’s really because data was not collected in October and half of November. So we’re going to get data, but we’re going to have to look at it carefully and with a somewhat skeptical eye by the time of the January meeting ….”
