The latest data from the Bureau of Economic Analysis shows that American consumers continued to open their wallets in May, with both personal income and spending climbing 0.7% from the previous month. But the report also contained a warning for anyone hoping for quick relief from high borrowing costs: the Federal Reserve's preferred inflation gauge, the personal consumption expenditures (PCE) price index, rose 0.4% for the second month in a row.
That combination—strong demand alongside stubborn price pressures—is exactly the kind of signal that keeps central bankers cautious. The headline PCE inflation rate now stands at 4.1% on a year-over-year basis, up from 3.8% in April. Even the core PCE measure, which strips out volatile food and energy prices, rose 0.3% in May, pushing its annual rate to 3.4% from 3.3%. Both remain well above the Fed's 2% target.
What the Numbers Show
The spending figure is particularly notable because it accelerated from April's 0.4% gain. After adjusting for inflation, what economists call "real" spending rose 0.3% in May, compared with a flat reading the month before. That suggests households are still willing to spend, even as prices remain elevated.
Income growth also picked up, matching the 0.7% pace of spending. That is a healthy sign for the broader economy, because when incomes rise in line with or ahead of spending, it reduces the need for households to take on more debt to maintain their lifestyle. Still, the fact that inflation is not cooling as quickly as many had hoped means the purchasing power of those extra dollars is being eroded.
Why the Fed Cares About PCE
The PCE price index is the Fed's go-to measure for inflation because it captures a broader range of spending patterns than the more commonly cited Consumer Price Index (CPI). It also adjusts more quickly for changes in what people actually buy—for example, if shoppers switch from expensive beef to cheaper chicken, PCE picks that up faster than CPI does.
When PCE readings come in hot month after month, it signals that the economy is still generating enough demand to keep prices rising. That makes it harder for the Fed to justify cutting interest rates, because lower rates would make borrowing cheaper and could fuel even more spending, potentially pushing inflation higher again.
This dynamic has been playing out for months. The Fed has held its benchmark interest rate at a range of 5.25% to 5.5% since July 2023, and recent comments from Fed officials suggest they are in no hurry to cut. The May PCE data reinforces that view.
What It Means for Investors
For everyday investors, the main takeaway is that borrowing costs are likely to stay elevated for a while longer. Credit card annual percentage rates (APRs), which are already at record highs, are unlikely to come down quickly. The same goes for variable-rate loans, new auto loans, and mortgages. If inflation stays sticky, the Fed has less room to ease policy, and that keeps upward pressure on the interest rates that banks charge consumers.
Bond markets have already been adjusting to this reality. Yields on longer-term Treasury bonds, which move inversely to prices, have been volatile as investors try to guess the timing of rate cuts. Higher yields make bonds more attractive relative to stocks, especially for sectors that rely on cheap financing, like real estate and small-cap companies.
Stock market investors should also pay attention. When inflation stays above target and the Fed stays tight, growth stocks—particularly in technology—tend to come under pressure because their future profits are discounted at higher rates. That is one reason why recent AI-driven optimism, as seen in Micron and Qualcomm AI forecasts lifting Nasdaq futures, has not translated into a broad market rally.
Broader Economic Context
The May data comes at a time when the global economy is sending mixed signals. In Europe, the Hungarian central bank cut its key rate to 6%, signaling confidence that inflation is under control there. But in the US, the story is different. The labor market remains tight, wage growth is still solid, and consumers keep spending—all of which give the Fed reason to hold steady.
Some economists argue that the year-over-year PCE rate will drift lower in the coming months as earlier high readings drop out of the calculation. But the monthly pace matters more for near-term policy decisions. Two consecutive 0.4% monthly gains suggest inflation is not falling fast enough to give the Fed comfort.
Investors will now watch the next few months of data closely. If PCE readings start to cool to 0.2% or below, the case for rate cuts will strengthen. If they stay at 0.3% or higher, the "higher for longer" narrative will persist, and that will keep pressure on both bond yields and stock valuations.
For now, the message from May is clear: the US consumer is still spending, but the price of that spending is that inflation is not going away quietly. That means patience remains the watchword for anyone managing a portfolio.
