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.
