The BEA’s personal income and outlays release for May provides a mixed message on PCE (personal consumption expenditure) inflation. Core PCE inflation which excludes the more volatile food and energy components rose from 2.58% to 2.68% on a year-over-year basis. This is the measure of inflation favored by the Federal Open Market Committee. The month-over-month rate popped up from 1.64% to 2.17% at an annual rate. And yet, our trend measure of inflation fell from 2.56% to 2.43%. Why the difference in these measures of inflation? Mechanically, the year-over-year rate is the average of the last 12 month-over-month inflation rates. The increase in the year-over-year inflation rate reflects the fact that this 12 month “window” added May 2024 (2.17%) while dropping May 2023 (0.98%). Meanwhile, our trend measure fell because the May 2024 month-over-month inflation rate (2.17%) is less than our trend measure for April (2.56%).

The picture is largely the same when looking at the overall PCE inflation rate: The month-over-month rate rose from 1.42% to 1.64%; the year-over-year rate edged up from 2.20% to 2.34%; and our trend measure eased from 2.25% to 2.04%.

The BEA release also shows a decline on a month-over-month basis in nominal personal consumption expenditures. However, this is a very volatile series. The year-over-year growth rate smooths out these fluctuations. Over the past few years, personal consumption expenditure growth has been falling. We place little importance in the month-over-month decline reported for May.

Real personal disposable income fell in May when computed on a month-over-month basis (its growth rate was negative) while the year-over-year growth rate declined.

Today, the University Of Michigan released its survey-based measure of inflation expectations over the next 12 months. In brief, consumers’ expectations of inflation have risen in 2025 and now sit at nearly 7%. Alternatively, the 5-year Breakeven Inflation Rate measures the average inflation rate over the next 5 years based on 5-Year Treasury Constant Maturity Securities and 5-Year Treasury Inflation-Indexed Constant Maturity Securities. Given that the inflation-indexed security is based on the CPI (consumer price index), and CPI inflation tends to run 0.5 percentage points higher than PCE inflation, it seems that investors expect inflation to average very close to the Fed’s 2% target.

The University of Michigan also released its measure of consumer sentiment (or “confidence”). While this series exhibits considerable volatility, it seems fair to say that consumer sentiment has dropped quite sharply in 2025.

Policy Implications
Is it time for the FOMC to start lowering its policy rate? Jockeying by potential candidates for the Chair of the FOMC suggests it is. Based on the data, it’s hard to make a strong case for lowering the Fed funds rate at this time. The data analyzed above tells us that inflation is still running a bit too hot relative to the Fed’s 2% target for core PCE inflation. The labor market continues to record solid employment gains. In about a month, we will get an initial reading on Gross Domestic Product for the second quarter, but at this juncture, it seems likely to be a solid quarter. One could argue that the FOMC can raise rates again if inflation pops up. But this sort of interest rate volatility is something that the Fed tries to avoid, and it always seems more difficult to raise rates than to lower them. In summary, the economic case points to maintaining the Fed funds rate at its current level.
The FOMC announcements have typically called for no change in policy in order to wait for more conclusive data, given the uncertainty in tariffs as well as geo-political concerns. There does not seem to be much in the way of additional clarification, other than PCE core inflation has been riding steadily above the Fed’s preferred target.
