Is Sugar All You Need?

Can prices of one type of good track inflation accurately? As we’ve discussed in a number of blog posts (for instance, here, here, and here), there is a debate among economists about which of the data series on the price level does the best job of tracking the underlying rate of inflation.

The most familiar data series on the price level is the consumer price index (CPI). Core CPI excludes the—typically volatile—food and energy prices. In gauging whether it is achieving its goal of 2 percent annual inflation, the Federal Reserve uses the personal consumption expenditures (PCE) price index. The PCE price index includes the prices of all the goods and services included in the consumption category of GDP, which makes it a broader measure of inflation than the CPI. To understand the underlying rate of inflation, the Fed often focuses on movements in core PCE.

With the increase in inflation that started in the spring of 2021, some economists noted that the prices of particular goods and services—such as new and used cars and housing—were increasing much more rapidly than other prices. So some economists concentrated on calculating inflation rates that excluded these or other prices from either the CPI or the PCE.

For example, the following figure shows the inflation rate measured by the percentage change from the same month in the previous year using the median CPI and using the trimmed mean PCE. If we list 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. The trimmed mean measure of PCE inflation 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. During the period when the inflation rate was increasing rapidly during 2021 and 2022, CPI inflation increased more and was more volatile than PCE inflation. That difference between movements in the two price level series is heightened when comparing median inflation in the CPI with trimmed mean inflation in the PCE. In particular, using trimmed mean PCE, the inflation of late 2021 and 2022 seems significantly milder than it does using median CPI.

The United States last experienced high inflation rates in the 1970s, when few people used personal computers and easily downloading macroeconomic data from the internet wasn’t yet possible. Today, it’s comparatively easy to download data on the CPI and PCE and manipulate them to investigate how the inflation rate would be affected by dropping the prices of various goods and services. It’s not clear, though, that this approach is always helpful in determining the underlying inflation rate. In a market system, the prices of many goods and services will be affected in a given month by shifts in demand and supply that aren’t related to general macroeconomic conditions.

In a recent blog post, economists B. Ravikumar and Amy Smaldone of the Federal Reserve Bank of St. Louis note that there is a strong correlation between movements in the prices of the “Sugar and Sweets” component of the CPI and movements in the overall CPI. Their post includes the following two figures. The first shows the price level since 1947 calculated using the prices of all the goods and services in the CPI (blue line) and the price level calculated just using the prices of goods included in the “Sugar and Sweets” category (red line). The data are adjusted to an index where the value for each series in January 1990 equals 100. The second figure shows the percentage change from the previous month for both series for the months since January 2000.

The two figures show an interesting—and perhaps surprising—correlation between sugar and sweets prices and all prices included in the CPI. The St. Louis Fed economists note that although the CPI is only published once per month, prices on sugar and sweets are available weekly. Does that mean that we could use prices on sugar and sweets to predict the CPI? That seems unlikely. First, consider that the sugar and sweets category of the CPI consists of three sub-categories:

  1. White, brown, and raw sugar and natural and artificial sweetners
  2. Chocolate and other types of candy, fruit flavored rolls, chewing gum and breath mints
  3. Other sweets, including jelly and jams, honey, pancake syrup, marshmallows, and chocolate syrup

Taken together these products are less than 3 percent of the products included in the CPI. In addition, the prices of the goods in this category can be heavily dependent on movements in sugar and cocoa prices, which are determined in world wide markets. For instance, the following figure shows the world price of raw cocoa, which soared in 2024 due to bad weather in West Africa, where most cocoa is grown. There’s no particular reason to think that factors affecting the markets for sugar and cocoa will also affect the markets in the United States for automobiles, gasoline, furniture, or most other products.

In fact, as the first figure below shows, if we look at the inflation rate calculated as the percentage change from the same month in the previous year, movements in sugar and sweets prices don’t track very closely movements in the overall CPI. Beginning in the summer of 2022—an important period when the inflation that began in the spring of 2021 peaked—inflation in sugar and sweets was much higher than overall CPI inflation. Anyone using prices of sugar and sweets to forecast what was happening to overal CPI inflation would have made very poor predictions. We get the same conclusion from comparing inflation calculated by compounding the current month’s rate over an entire year: Inflation in sugar and sweets prices is much more volatile than is overall CPI inflation. That conclusion is unsurprising given that food prices are generally more volatile than are the prices of most other goods.

It can be interesting to experiment with excluding various prices from the CPI or the PCE or with focusing on subcategories of these series. But it’s not clear at this point whether any of these adjustments to the CPI and the PCE, apart from excluding all food and energy prices, gives an improved estimate of the underlying rate of inflation.

Latest Monthly Report on PCE Inflation Confirms Inflation Remains Stubbornly High

Federal Reserve Chair Jerome Powell (Photo from federalreserve.gov)

In a post yesterday, we noted that the quarterly data on the personal consumption expenditures (PCE) price index in the latest GDP report released by the Bureau of Economic Analysis (BEA) indicated that inflation was running higher than expected. Today (April 26), the BEA released its “Personal Income and Outlays” report for March, which includes monthly data on the PCE. The monthly data are consistent with the quarterly data in showing that PCE inflation remains higher than the Federal Reserve’s 2 percent annual inflation target. (A reminder that PCE inflation is particularly important because it’s the inflation measure the Fed uses to gauge whether it’s hitting its inflation target.)

The following figure shows PCE inflation (blue line) and core PCE inflation (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. Many economists believe that core inflation gives a better gauge of the underlying inflation rate. Measured this way, PCE inflation increased from 2.5 percent in February to 2.7 percent in March. Core PCE inflation remained unchanged at 2.8 percent.

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 declined from 4.1 percent in February to 3.9 percent in March. Core PCE inflation increased from 3.2 percent in February to 3.9 in March. So, March was another month in which both PCE inflation and core PCE inflation remained well above the Fed’s 2 percent inflation target.

 

The following figure shows other ways 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 rate of inflation (the blue line) excluding the prices of housing, food, and energy. Fed Chair Jerome Powell has said that he is particularly concerned by elevated rates of inflation in services. Some economists believe that the price of housing isn’t accurately measured in the PCE, which makes it interesting to see if excluding the price of housing makes much difference in calculating the inflation rate. All three measures of inflation increased from February to March, with inflation in services remaining well above overall inflation and inflation excluding the prices of housing, food, and energy being somewhat lower than overall inflation.

The following figure uses the same three inflation measures as the figure above, but shows the 1-month inflation rate rather than the 12-month inflation rate. Measured this way, inflation in services increased sharply from 3.2 percent in February to 5.0 percent in March. Inflation excluding the prices of housing, food, and energy doubled from 2.0 percent in February to 4.1 percent in March.

Overall, the data in this report indicate that the decline in inflation during the second half of 2023 hasn’t continued in the first three months of 2024. In fact, the inflation rate may be slightly increasing. As a result, it no longer seems clear that the Fed’s policy-making Federal Open Market Committee (FOMC) will cut its target for the federal funds rate this year. (We discuss the possibility that the FOMC will keep its target unchanged through the end of the year in this blog post.) At the press conference following the FOMC’s next meeting on April 30-May 1, Fed Chair Jerome Powell may explain what effect the most recent data have had on the FOMC’s planned actions during the remainder of the year.

Does the Latest GDP Report Indicate the U.S. Economy Is Entering a Period of Stagflation?

This morning, Thursday April 25, the Bureau of Economic Analysis (BEA) released its advance estimate of real GDP growth during the first quarter of 2024. The two most striking points in the report are, first, that real GDP increased in the first quarter at an annual rate of only 1.6 percent—well below the 2.5 percent increase expected in a survey of economists and the 2.7 percent increase indicated by the Federal Reserve Bank of Atlanta’s GDPNow forecast. As the following figure shows, the growth rate of real GDP has declined in each of the last two quarters from the very strong growth rate of 4.9 percent during the third quarter of 2023.  

The second striking point in the report was an unexpected increase in inflation, as measured using the personal consumption expenditures (PCE) price index. As the following figure shows, PCE inflation (the red line), measured as a compound annual rate of change, increased from 1.8 percent in the fourth quarter of 2023 to 3.4 percent in the first quarter of 2024. Core PCE inflation (the blue line), which excludes food and energy prices, increased from 2.0 percent in the fourth quarter of 2023 to 3.7 percent in the first quarter of 2024. These data indicate that inflation in the first quarter of 2024 was running well above the Federal Reserve’s 2.0 percent target.

A combination of weak economic growth and above-target inflation poses a policy dilemma for the Fed. As we discuss in Macroeconomics, Chapter 13, Section 13.3 (Economics, Chapter 23, Section 23.3), the combination of slow growth and inflation is called stagflation. During the 1970s, when the U.S. economy suffered from stagflation, Fed Chair Arthur Burns (whose photo appears at the beginning of this post) was heavily criticized by members of Congress for his inability to deal with the problem. Stagflation poses a dilemma for the Fed because using an expansionary monetary policy to deal with slow economic growth may cause the inflation rate to rise. Using a contractionary monetary policy to deal with high inflation can cause growth to slow further, possibly pushing the economy into a recession.

Is Fed Chair Jerome Powell in as difficult a situation as Arthur Burns was in the 1970s? Not yet, at least. First, Burns faced a period of recession—declining real GDP and rising unemployment—whereas currently, although economic growth seems to be slowing, real GDP is still rising and the unemployment rate is still below 4 percent. In addition, the inflation rate in these data are below 4 percent, far less than the 10 percent inflation rates during the 1970s.

Second, it’s always hazardous to draw conclusions on the basis of a single quarter’s data. The BEA’s real GDP estimates are revised several times, so that the value for the first quarter of 2024 may well be revised significantly higher (or lower) in coming months.

Third, the slow rate of growth of real GDP in the first quarter is accounted for largely by a surge in imports—which are subtracted from GDP—and a sharp decline in inventory investment. Key components of aggregate demand remained strong: Consumption expenditures increased at annual rate of 2.5 per cent and business investment increased at an annual rate of 3.2 percent. Residential investment was particularly strong, growing at an annual rate 0f 13.2 percent—despite the effects of rising mortgage interest rates. One way to strip out the effects of net exports, inventory investment, and government purchases—which can also be volatile—is to look at 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 declined only modertately from 3.3 percent in the fourth quarter of 2023 to 3.1 percent in the first quarter of 2024.

Looking at these details of the GDP report indicate that growth may have slowed less during the first quarter than the growth rate of real GDP seems to indicate. Investors on Wall Street may have come to this same conclusion. As shown by this figure from the Wall Street Journal, shows that stock prices fell sharply when trading opened at 9:30 am, but by 2 pm has recovered some of their losses as investors considered further the implications of the GDP report. (As we discuss in Macroeconomics, Chapter 6, Section 6.2 and Economics, Chapter 8, Section 8.2, movements in stock price indexes can provide some insight into investors’ expectations of future movements in corporate profits, which, in turn, depend in part on future movements in economic growth.)

Finally, we may get more insight into the rate of inflation tomorrow morning when the BEA releases its report on “Personal Income and Outlays,” which will include data on PCE inflation during March. The monthly PCE data provide more current information than do the quarterly data in the GDP report.

In short, today’s report wasn’t good news, but may not have been as bad as it appeared at first glance. We are far from being able to conclude that the U.S. economy is entering into a period of stagflation.

Latest PCE Report Shows Moderate, but Persistent, Inflation

Inflation as measured by 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 changes in personal consumption expenditures (PCE) price index when evaluating whether it is meeting its 2 percent inflation target. The Bureau of Economic Analysis (BEA) released PCE data for February as part of its “Personal Income and Outlays” report on March 29.  

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 PCE from the same month in the previous year. Measured this way, PCE inflation increased slightly from 2.4 percent in January to 2.5 percent in February. Core PCE inflation decreased slightly from 2.9 percent to 2.8 percent.

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, both PCE inflation and core PCE inflation declined in February, but the decline only partly offset the sharp increases in December and January. Both PCE inflation—at 4.1 percent—and core PCE inflation—at 3.2 percent—remained well above the Fed’s 2 percent target. 

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 has said that he is particularly concerned by 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.

In February, 12-month trimmed mean PCE inflation was 3.1 percent, a little below core inflation of 3.3 percent. Twelve-month inflation in services was 3.8 percent, a slight decrease from 3.9 percent in January. Trimmed mean and services inflation tell the same story as PCE and PCE core inflation: Inflation has decline significantly from its highs of mid-2022, but remains stubbornly above the Fed’s 2 percent target.

It seems unlikely that this month’s PCE data will have much effect on when the members of the Federal Open Market Committee will decide to lower the target for the federal funds rate.

Another Steady-as-She-Goes FOMC Meeting

As always, economists and investors had been awaiting the outcome of today’s meeting of the Federal Reserve’s policy-making Federal Open Market Committee (FOMC) to get further insight into future monetary policy. The expectation has been that the FOMC would begin reducing its target for the federal funds rate, mostly likely beginning with its meeting on June 11-12. Financial markets were expecting that the FOMC would make three 0.25 percentage point cuts by the end of the year, reducing its target range from the current 5.25 to 5.50 percent to 4.50 to 4.75 percent.

There appears to be nothing in the committees statement (found here) or in Powell’s press conference following the meeting to warrant a change in expectations of future Fed policy. The committee’s statement noted that: “The Committee does not expect it will be appropriate to reduce the target range until it has gained greater confidence that inflation is moving sustainably toward 2 percent.” As Powell stated in his press conference, although the committee found the general trend in inflation data to be encouraging, they would have to see additional months of data that were consistent with their 2 percent inflation target before reducing their target for the federal funds rate.

As we’ve noted in earlier blog posts (here, here, and here), inflation during January and February has been somewhat higher than expected. Some economists and investors had wondered if, as a result, the committee might delay its first cut in the federal funds target range or implement only two cuts rather than three. In his press conference, Powell seemed unconcerned about the January and February data and expected that falling inflation rates of the second half of 2023 to resume.

Typically, at the FOMC’s December, March, June, and September meetings, the committee releases a “Summary of Economic Projections” (SEP), which presents median values of the committee members’ forecasts of key economic variables.

The table shows that the committee members made relatively small changes to their projections since their December meeting. Most notable was an increase in the median projection of growth in real GDP for 2024 from 1.4 percent at the December meeting to 2.1 percent at this meeting. Correspondingly, the median projection of unemployment during 2024 dropped from 4.1 percent to 4.0 percent. The key projection of the value of the federal funds rate at the end of 2024 was left unchanged at 4.6 percent. As noted earlier, that rate is consistent with three 0.25 percent cuts in the target range during the remainder of the year.

The SEP also includes a “dot plot.” Each dot in the plot represents the projection of an individual committee member. (The committee doesn’t disclose which member is associated with which dot.) Note that there are 19 dots, representing the 7 members of the Fed’s Board of Governors and the 12 presidents of the Fed’s district banks. Although only the president of the New York Fed and the presidents of 4 of the 11 district banks are voting members of the committee, all the district bank presidents attend the committee meetings and provide economic projections.

The plots on the far left of the figure represent the projections of each of the 19 members of the value of the federal funds rate at the end of 2024. These dots are bunched fairly closely around the median projection of 4.6 percent. The dots representing the projections for 2025 and 2026 are more dispersed, representing greater uncertainty among committee members about conditions in the future. The dots on the far right represent the members’ projections of the value of the federal funds rate in the long run. As Table 1 shows, the median projected value is 2.6 percent (up slightly from 2.5 percent in December), although the plot indicates that all but one member expects that the long-run rate will be 2.5 percent or higher. In other words, few members expect a return to the very low federal funds rates of the period from 2008 to 2016.

Key Macro Data Series during the Time Since the Arrival of Covid–19 in the United States

Four years ago, in mid-March 2020, Covid–19 began to significantly affect the U.S. economy, with hospitalizations rising and many state and local governments closing schools and some businesses. In this blog post we review what’s happened to key macro variables during the past four years. Each monthly series starts in February 2020 and the quarterly series start in the fourth quarter of 2019.

Production

Real GDP declined by 5.8 percent from the fourth quarter of 2019 to the first quarter of 2020 and by an additional 28.0 percent from the first quarter of 2020 to the second quarter. This decline was by far the largest in such a short period in the history of the United States. From the second quarter to the third quarter of 2020, as businesses began to reopen, real GDP increased by 34.8 percent, which was by far the largest increase in a single quarter in U.S. history.

Industrial production followed a similar—although less dramatic—path to real GDP, declining by 16.8 percent from February 2020 to April 2020 before increasing by 12.3 percent from April 2020 to June 2020. Industrial production did not regain its February 2020 level until March 2022. The swings in industrial production were smaller than the swings in GDP because industrial production doesn’t include the output of the service sector, which includes firms like restaurants, movie theaters, and gyms that were largely shutdown in some areas. (Industrial production measures the real output of the U.S. manufacturing, mining, and electric and gas utilities industries. The data are issued by the Federal Reserve and discussed here.)

Employment

Nonfarm payroll employment, collected by the Bureau of Labor Statistics (BLS) in its establishment survey, followed a path very similar to the path of production. Between February and April 2020, employment declined by an astouding 22 million workers, or by 14.4 percent. This decline was by far the largest in U.S. history over such a short period. Employment increased rapidly beginning in April but didn’t regain its February 2020 level until June 2022.

The employment-population ratio measures the percentage of the working-age population that is employed. It provides a more comprehensive measure of an economy’s utilization of available labor than does the total number of people employed. In the following figure, the blue line shows the employment-population ratio for the whole working-age population and the red line shows the employment-population ratio for “prime age workers,” those aged 25 to 54.

For both groups, the employment-population ratio plunged as a result of Covid and then slowly recovered as the production began increasing after April 2020. The employment-population ratio for prime age workers didn’t regain its February 2020 value until February 2023, an indication of how long it took the labor market to fully overcome the effects of the pandemic. As of February 2024, the employment-population ratio for all people of working age hasn’t returned to its February 2020 value, largely because of the aging of the U.S. population.

Average weekly hours worked followed an unusual pattern, declining during March 2020 but then increasing to beyond its February 2020 level to a peak in April 2021. This increase reflects firms attempting to deal with a shortage of workers by increasing the hours of those people they were able to hire. By April 2023, average weekly hours worked had returned to its February 2020 level.

Income

Real average hourly earnings surged by more than six percent between February and April 2020—a very large increase over a two-month period. But some of the increase represented a composition effect—as workers with lower incomes in services industries such as restaurants were more likely to be out of work during this period—rather than an actual increase in the real wages received by people employed during both months. (Real average hourly earnings are calculated by dividing nominal average hourly earnings by the consumer price index (CPI) and multiplying by 100.)

Median weekly real earnings, because it is calculated as a median rather than as an average (or mean), is less subject to composition effects than is real average hourly earnings. Median weekly real earnings increased sharply between February and April of 2020 before declining through June 2022. Earnings then gradually increased. In February 2024 they were 2.5 percent higher than in February 2020.

Inflation

The inflation rate most commonly mentioned in media reports is the percentage change in the CPI from the same month in the previous year. The following figure shows that inflation declined from February to May 2020. Inflation then began to rise slowly before rising rapidly beginning in the spring of 2021, reaching a peak in June 2022 at 9.0 percent. That inflation rate was the highest since November 1981. Inflation then declined steadily through June 2023. Since that time it has fluctuated while remaining above 3 percent.

As we discuss in Macroeconomics, Chapter 15, Section 15.5 (Economics, Chapter 25, Section 25.5), the Federal Reserve gauges its success in meeting its goal of an inflation rate of 2 percent using the personal consumption expenditures (PCE) price index. The following figure shows that PCE inflation followed roughly the same path as CPI inflation, although it reached a lower peak and had declined below 3 percent by November 2023. (A more detailed discussion of recent inflation data can be found in this post and in this post.)

Monetary Policy

The following figure shows the effective federal funds rate, which is the rate—nearly always within the upper and lower bounds of the Fed’s target range—that prevails during a particular period in the federal funds market. In March 2020, the Fed cut its target range to 0 to 0.25 percent in response to the economic disruptions caused by the pandemic. It kept the target unchanged until March 2022 despite the sharp increase in inflation that had begun a year earlier. The members of the Federal Reserve’s Federal Open Market Committee (FOMC) had initially hoped that the surge in inflation was largely caused by disuptions to supply chains and would be transitory, falling as supply chains returned to normal. Beginning in March 2022, the FOMC rapidly increased its target range in response to continuing high rates of inflation. The targer range reached 5.25 to 5.50 percent in July 2023 where it has remained through March 2024.

 

Although the money supply is no longer the focus of monetary policy, some economists have noted that the rate of growth in the M2 measure of the money supply increased very rapidly just before the inflation rate began to accelerate in the spring of 2021 and then declined—eventually becoming negative—during the period in which the inflation rate declined.

As we discuss in the new 9th edition of Macroeconomics, Chapter 15, Section 15.5 (Economics, Chapter 25, Section 25.5), some economists believe that the FOMC should engage in nominal GDP targeting. They argue that this approach has the best chance of stabilizing the growth rate of real GDP while keeping the inflation rate close to the Fed’s 2 percent target. The following figure shows the economy experienced very high rates of inflation during the period when nominal GDP was increasing at an annual rate of greater than 10 percent and that inflation declined as the rate of nominal GDP growth declined toward 5 percent, which is closer to the growth rates seen during the 2000s. (This figure begins in the first quarter of 2000 to put the high growth rates in nominal GDP of 2021 and 2022 in context.)

Fiscal Policy

As we discuss in the new 9th edition of Macroeconomics, Chapter 15 (Economics, Chapter 25), in response to the Covid pandemic Congress and Presidents Trump and Biden implemented the largest discretionary fiscal policy actions in U.S. history. The resulting increases in spending are reflected in the two spikes in federal government expenditures shown in the following figure.

The initial fiscal policy actions resulted in an extraordinary increase in federal expenditures of $3.69 trillion, or 81.3 percent, from the first quarter to the second quarter of 2020. This was followed by an increase in federal expenditures of $2.31 trillion, or 39.4 percent, from the fourth quarter of 2020 to the first quarter of 2021. As we recount in the text, there was a lively debate among economists about whether these increases in spending were necessary to offest the negative economic effects of the pandemic or whether they were greater than what was needed and contributed substantially to the sharp increase in inflation that began in the spring of 2021.

Saving

As a result of the fiscal policy actions of 2020 and 2021, many households received checks from the federal government. In total, the federal government distributed about $80o billion directly to households. As the figure shows, one result was to markedly increase the personal saving rate—measured as personal saving as a percentage of disposable personal income—from 6.4 percent in December 2019 to 22.0 in April 2020. (The figure begins in January 2020 to put the size of the spike in the saving rate in perspective.) 

The rise in the saving rate helped households maintain high levels of consumption spending, particularly on consumer durables such as automobiles. The first of the following figure shows real personal consumption expenditures and the second figure shows real personal consumption expenditures on durable goods.

Taken together, these data provide an overview of the momentous macroeconomic events of the past four years.

Consumer Price Inflation Comes in Somewhat Higher than Expected

Federal Reserve Chair Jerome Powell (Photo from Bloomberg News via the Wall Street Journal.)

Economists, policymakers, and Wall Street analysts have been waiting for macroeconomic data to confirm that the Federal Reserve has brought the U.S. economy in for a soft landing, with inflation arrving back at the Fed’s target of 2 percent without the economy slipping into a recession. Fed officials have been cautious about declaring that they have yet seen sufficient data to be sure that a soft landing has actually been achieved. Accordingly, they are not yet willing to begin cutting their target for the federal funds rate.

For instance, on March 6, in testifying before the Commitee on Financial Services of the U.S. House of Representatives, Fed Chair Jerome Powell stated that the Fed’s Federal Open Market Committee (FOMC) “does not expect that it will be appropriate to reduce the target range until it has gained greater confidence that inflation is moving sustainably toward 2 percent.” (Powell’s statement before his testimony can be found here.)

The BLS’s release today (March 12) of its report on the consumer price index (CPI) (found here) for February indicated that inflation was still running higher than the Fed’s target, reinforcing the cautious approach that Powell and other members of the FOMC have been taking. The increase in the CPI that includes the prices of all goods and services in the market basket—often called headline inflation—was 3.2 percent from the same month in 2023, up slightly from 3.1  In January. (We discuss how the BLS constructs the CPI in Macroeconomics, Chapter 9, Section 19.4, Economics, Chapter 19, Section 19.4, and Essentials of Economics, Chapter 3, Section 13.4.) As the following figure shows, core inflation—which excludes the prices of food and energy—was 3.8 percent, down slightly from 3.9 percent in January.

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 values are more concerning, as indicated in the following figure. Headline CPI inflation is 5.4 percent (up from 3.7 percent in January) and core CPI inflation is 4.4 percent (although that is down from 4.8 percent in January). The Fed’s inflation target is measured using the personal consumption expenditures (PCE) price index, not the CPI. But CPI inflation at these levels is not consistent with PCE inflation of only 2 percent.

Even more concerning is the path of inflation in the prices of services. As we’ve noted in earlier posts, Chair Powell has emphasized that as supply chain problems have gradually been resolved, inflation in the prices of goods has been rapidly declining. But inflaion in services hasn’t declined nearly as much. Last summer he stated the point this way:

“Part of the reason for the modest decline of nonhousing services inflation so far is that many of these services were less affected by global supply chain bottlenecks and are generally thought to be less interest sensitive than other sectors such as housing or durable goods. Production of these services is also relatively labor intensive, and the labor market remains tight. Given the size of this sector, some further progress here will be essential to restoring price stability.”

The following figure shows the 1-month inflation rate in services prices and in services prices not included including housing rent. Some economists believe that the rent component of the CPI isn’t well measured and can be volatile, so it’s worthwhile to look at inflation in service prices not including rent. The figure shows that inflation in all service prices has been above 4 percent in every month since July 2023. Although inflation in service prices declined from January, it was still a very high 5.8 percent in February. Inflation in service prices not including housing rent was even higher at 7.5 percent. Such large increases in the prices of services, if they were to continue, wouldn’t be consistent with the Fed meeting its 2 percent inflation target.

Finally, some economists and policymakers look at median inflation to gain insight into the underlying trend in the inflation rate. 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. As the following figure shows, although median inflation declined in February, it was still high at 4.6 percent and, although median inflation is volatile, the trend has been generally upward since July 2023.

The data in this month’s BLS report on the CPI reinforces the view that the FOMC will not move to cut its target for the federal funds rate in the meeting next week and makes it somewhat less likely that the committee will cut its target at the following meeting on April 30-May 1.

The Latest PCE Report and PCE Inflation v. CPI Inflation

Wall Street Journal columnist Justin Lahart notes that when the Bureau of Labor Statistics (BLS) releases its monthly report on the consumer price index (CPI), the report “generates headlines, features in politicians’ speeches and moves markets.” When the Bureau of Economic Analysis (BEA) releases its monthly report “Personal Income and Outlays,” which includes data on the personal consumption expenditures (PCE) price index, there is much less notice in the business press or, often, less effect on financial markets. (You can see the difference in press coverage by comparing the front page of today’s online edition of the Wall Street Journal after the BEA released the latest PCE data with the paper’s front page on February 13 when the BLS released the latest CPI data.)

This difference in the weight given to the two inflation reports seems curious because the Federal Reserve uses the PCE, not the CPI, to determine whether it is achieving its 2 percent annual inflation target. When a new monthly measure of inflation is released much of the discussion in the media is about the effect the new data will have on the Federal Open Market Committee’s (FOMC) decision on whether to change its target for the federal funds rate. You might think the result would be greater media coverage of the PCE than the CPI. (The PCE includes the prices of all the goods and services included in the consumption component of GDP. Because the PCE includes the prices of more goods and services than does the CPI, it’s a broader measure of inflation, which is the key reason that the Fed prefers it.)

That CPI inflation data receive more media discussion than PCE inflation data is likely due to three factors:

  1. The CPI is more familiar to most people than the PCE. It is also the measure that politicians and political commentators tend to focus on. The media are more likely to highlight a measure of inflation that the average reader easily understands rather than a less familiar measure that would require an explanation. 
  2. The monthly report on the CPI is typically released about two weeks before the monthly report on the PCE. Therefore, if the CPI measure of inflation turns out to be higher or lower than expected, the stock and bond markets will react to this new information on the value of inflation in the previous month. If the PCE measure is roughly consistent with the CPI measure, then the release of new data on the PCE measure contains less new information and, therefore, has a smaller effect on stock and bond prices.
  3. Over longer periods, the two measures of inflation often move fairly closely together as the following figure shows, although CPI inflation tends to be somewhat higher than PCE inflation. The values of both series are the percentage change in the index from the same month in the previous year.

Turning to the PCE data for January released in the BEA’s latest “Personal Income and Outlays” report, the PCE inflation data were broadly consistent with the CPI data: Inflation in January increased somewhat from December. The first of the following figures shows PCE inflation and core PCE inflation—which excludes energy and food prices—for the period since January 2015 with inflation measured as the change in PCE from the same month in the previous year.  The second figure shows PCE inflation and core PCE inflation measured as the inflation rate calculated by compounding the current month’s rate over an entire year. (The first figure shows what is sometimes called 12-month inflation and the second figure shows 1-month inflation.)

The two inflation measures are telling markedly different stories: 12-month inflation shows a continuation in the decline in inflation that began in 2022. Twelve-month PCE inflation fell from 2.6 percent in December to 2.4 percent in January. Twelve-month core PCE inflation fell from 2.9 percent in December to 2.8 percent in December. So, by this measure, inflation continues to approach the Fed’s 2 percent inflation target.

One-month PCE and core PCE inflation both show sharp increases from December to January: From 1.4 percent in December to 4.2 percent for 1-month PCE inflation and from 1.8 percent in December to 5.1 percent in January for 1-month core PCE inflation.

The one-month inflation data are bad news in that they may indicate that inflation accelerated in January and that the Fed is, therefore, further away than it seemed in December from hitting its 2 percent inflation target. But it’s important not to overinterpret a single month’s data. Although 1-month inflation is more volatile than 12-month inflation, the broad trend in 1-month inflation had been downwards from mid-2022 through December 2023. It will take at least a more months of data to assess whether this trend has been broken.

Fed officials didn’t appear to be particularly concerned by the news. For instance, according to an article on bloomberg.com, Federal Reserve Bank of Atlanta President Raphael Bostic noted that: “The last few inflation readings—one came out today—have shown that this is not going to be an inexorable march that gets you immediately to 2%, but that rather there are going to be some bumps along the way.” Investors appear to continue to expect that the Fed will cut its target for the federal funds rate at its meeting on June 11-12.

Surprisingly Strong CPI Report

As we’ve discussed in several blog posts (for instance, here and here), recent macro data have been consistent with the Federal Reserve being close to achieving a soft landing. The Fed’s increases in its target for the federal funds rate have slowed the growth of aggregate demand sufficiently to bring inflation closer to the Fed’s 2 percent target, but haven’t, to this point, slowed the growth of aggregate demand so much that the U.S. economy has been pushed into a recession.

By January 2024, many investors in financial markets and some economists were expecting that at its meeting on March 19-20, the Fed’s Federal Open Market Committee would be cutting its target for the federal funds. However, members of the committee—notably, Chair Jerome Powell—have been cautious about assuming prematurely that inflation had, in fact, been brought under control. In fact, in his press conference on January 31, following the committee’s most recent meeting, Powell made clear that the committee was unlikely to reduce its target for the federal funds rate at its March meeting. Powell noted that “inflation is still too high, ongoing progress in bringing it down is not assured, and the path forward is uncertain.”

Powell’s caution seemed justified when, on February 2, the Bureau of Labor Statistics (BLS) released its most recent “Employment Situation Report” (discussed in this post). The report’s data on growth in employment and growth in wages, as measured by the change in average hourly earnings, might be indicating that aggregate demand is growing too rapidly for inflation to continue to decline.

The BLS’s release today (February 13) of its report on the consumer price index (CPI) (found here) for January provided additional evidence that the Fed may not yet have put inflation on a firm path back to its 2 percent target. The average forecast of economists surveyed before the release of the report was that the increase in the version of the CPI that includes the prices of all goods and services in the market basket—often called headline inflation—would be 2.9 percent. (We discuss how the BLS constructs the CPI in Macroeconomics, Chapter 9, Section 19.4, Economics, Chapter 19, Section 19.4, and Essentials of Economics, Chapter 3, Section 13.4.) As the following figure shows, headline inflation for January was higher than expected at 3.1 percent (measured by the percentage change from the same month in the previous year), while core inflation—which excludes the prices of food and energy—was 3.9 percent. Headline inflation was lower than in December 2023, while core inflation was almost unchanged.

Although the values for January might seem consistent with a gradual decline in inflation, that conclusion may be misleading. Headline inflation in January 2023 had been surprisingly high at 6.4 percent. Hence, the comparision between the value of the CPI in January 2024 with the value in January 2023 may be making the annual CPI inflation rate seem artificially low. 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 values are more concerning, as indicated in the following figure. Headline CPI inflation is 3.7 percent and core CPI inflation is 4.8 percent.

Even more concerning is the path of inflation in the prices of services. Chair Powell has emphasized that as supply chain problems have gradually been resolved, inflation in the prices of goods has been rapidly declining. But inflaion in services hasn’t declined nearly as much. Last summer he stated the point this way:

“Part of the reason for the modest decline of nonhousing services inflation so far is that many of these services were less affected by global supply chain bottlenecks and are generally thought to be less interest sensitive than other sectors such as housing or durable goods. Production of these services is also relatively labor intensive, and the labor market remains tight. Given the size of this sector, some further progress here will be essential to restoring price stability.”

The following figure shows the 1-month inflation rate in services prices. The figure shows that inflation in services has been above 4 percent in every month since July 2023. Inflation in services was a very high 8.7 percent in January. Clearly such large increases in the prices of services aren’t consistent with the Fed meeting its 2 percent inflation target.

How should we interpret the latest CPI report? First, it’s worth bearing in mind that a single month’s report shouldn’t be relied on too heavily. There can be a lot of volatility in the data month-to-month. For instance, inflation in the prices of services jumped from 4.7 percent in December to 8.7 percent in January. It seems unlikely that inflation in the prices of services will continue to be over 8 percent.

Second, housing prices are a large component of service prices and housing prices can be difficult to measure accurately. Notably, the BLS includes in its measure the implicit rental price that someone who owns his or her own home pays. The BLS calculates that implict rental price by asking consumers who own their own homes the following question: “If someone were to rent your home today, how much do you think it would rent for monthly, unfurnished and without utilities?” (The BLS discusses how it measures the price of housing services here.) In practice, it may be difficult for consumers to accurately answer the question if very few houses similar to theirs are currently for rent in their neighborhood.

Third, the Fed uses the personal consumption expenditures (PCE) price index, not the CPI, to gauge whether it is achieving its 2 percent inflation target. The Bureau of Economic Analysis (BEA) includes the prices of more goods and services in the PCE than the BLS includes in the CPI and measures housing services using a different approach than that used by the BLS. Although inflation as measured by changes in the CPI and as measured by changes in the PCE move roughly together over long periods, the two measures can differ significantly over a period of a few months. The difference between the two inflation measures is another reason not to rely too heavily on a single month’s CPI data.

Despite these points, investors on Wall Street clearly interpreted the CPI report as bad news. Investors have been expecting that the Fed will soon cut its target for the federal funds rate, which should lead to declines in other key interest rates. If inflation continues to run well above the Fed’s 2 percent target, it seems likely that the Fed will keep its federal funds target at its current level for longer, thereby slowing the growth of aggregate demand and raising the risk of a recession later this year. Accordingly, the Dow Jones Industrial Average declined by more than 500 points today (February 13) and the interest rate on the 10-year Treasury note rose above 4.3 percent.

The FOMC has more than a month before its next meeting to consider the implications of the latest CPI report and the additional macro data that will be released in the meantime.

FOMC Meeting: Steady as She Goes

Federal Reserve Chair Jerome Powell (Photo from the New York Times.)

This afternoon, Wednesday, January 31, the Federal Reserve’s Federal Open Market Committee (FOMC) held the first of its eight scheduled meetings during 2024. As we noted in a recent post, macroeconomic data have been indicating that the Fed is close to achieving its goal of bringing the U.S. economy in for a soft landing—reducing inflation down to the Fed’s 2 percent target without pushing the economy into a recession. But as we also noted in that post, it was unlikely that at this meeting Fed Chair Jerome Powell and the other members of the FOMC would declare victory in their fight to reduce inflation from the high levels it reached during 2022.

In fact, in Powell’s press conference following the meeting, when asked directly by a reporter whether he believed that the economy had made a safe landing, Powell said that he wasn’t yet willing to draw that conclusion. Accordingly, the committee kept its target range for the federal funds rate unchanged at 5.25 percent to 5.50 percent. This was the fifth meeting in a row at which the FOMC had left the target unchanged. Although some policy analysts expect that the FOMC might reduce its federal funds rate target at its next meeting in March, the committee’s policy statement made that seem unlikely:

“In considering any adjustments to the target range for the federal funds rate, the Committee will carefully assess incoming data, the evolving outlook, and the balance of risks. The Committee does not expect it will be appropriate to reduce the target range until it has gained greater confidence that inflation is moving sustainably toward 2 percent.”

Powell reinforced the point during his press conference by stating it was unlikely that the committee would cut the target rate at the next meeting. He noted that:

“The economy has surprised forecasters in many ways since the pandemic, and ongoing progress toward our 2 percent inflation objective is not assured. The economic outlook is uncertain, and we remain highly attentive to inflation risks. We are prepared to maintain the current target range for the federal funds rate for longer, if appropriate.”

Powell highlighted a couple of areas of potential concern. The Fed gauges its progress towards achieving its 2 percent inflation goal using the percentage change in the personal consumption expenditures (PCE) price index. As we noted in a recent post, PCE inflation has declined from a high of 7.1 percent in June 2022 to 2.9 percent in December 2023. But Powell noted that PCE inflation in goods has followed a different path from PCE inflation in services, as the following figure shows.

Inflation during 2022 was much greater in the prices of goods than in the prices of services, reflecting the fact that supply chain disruptions caused by the pandemic had a greater effect on goods than on services. Inflation in goods has been less than 1 percent every month since June 2023 and has been negative in three of those months. Inflation in services peaked in February 2023 at 6.0 percent and has been declining since, but was still 3.9 percent in December. Powell noted that the very low rates of inflation in the prices of goods probably aren’t sustainable. If inflation in the prices of goods increases, the Fed may have difficulty achieving its 2 percent inflation target unless inflation in the prices of services slows.

Powell also noted that the most recent data on the employment cost index (ECI) had been released the morning of the meeting. The ECI is compiled by the Bureau of Labor Statistics and is published quarterly. It measures the cost to employers per employee hour worked. The BLS publishes data that includes only wages and salaries and data that includes, in addition to wages and salaries, non-wage benefits—such as contributions to retirement accounts or health insurance—that firms pay workers. The figure below shows the percentage change from the same month in the previous year for the ECI including just wages and salaries (blue line) and for the ECI including all compensation (red line). Although ECI inflation has declined significantly from its peak in he second quarter of 2022, in the fourth quarter of 2023, both measures of ECI inflation were above 4 percent. Wages increasing at that pace may not be consistent with a 2 percent rate of price inflation.

Powell’s tone at his news conference (which can be watched here) was one of cautious optimism. He and the other committee members expect to be able to cut the target for the federal funds rate later this year but remain on guard for any indications that the inflation rate is increasing again.
