The Federal Reserve’s preferred inflation gauge came in below forecasts for August, holding at 3.4 percent on an annual basis against a consensus estimate of 3.7 percent.
What did the report show?
Annual PCE inflation was unchanged at 3.4 percent, with the July figure revised down from 3.7 percent to the same level. On a monthly basis prices rose 0.3 percent against a 0.4 percent forecast. Core inflation, which strips out food and energy, held at 3 percent annually and rose 0.2 percent for the month, both marginally under expectations.
Why does this measure matter more than others?
Because the Fed uses it. Personal consumption expenditures differ from the more widely reported consumer price index in how they weight spending, accounting for substitution when consumers switch between goods as prices change, and including costs paid on a household’s behalf such as employer funded medical care. The two measures typically diverge, and PCE usually runs lower.
Is 3.4 percent good?
Lower than expected and still well above target. The Fed aims for 2 percent annual inflation, which means this reading sits roughly 1.4 points above where the central bank wants it. Coming in below forecast is not the same as being where policymakers need it to be, and coverage frequently conflates the two.
How much should the miss be weighted?
Moderately. Three tenths on the headline and two tenths on core is a real miss but not a dramatic one, and part of the picture comes from the July revision rather than from August activity. Monthly inflation data is routinely revised, sometimes substantially, and a single report rarely changes a trajectory on its own.
What does core inflation indicate?
Underlying persistence. Food and energy prices swing on weather, harvests and geopolitics, which is why core is treated as the better signal of where inflation is heading. Core PCE inflation at 3 percent, below the headline figure, suggests some of the current pressure is coming from the volatile components rather than being embedded across the economy.
Which volatile component is doing the work?
Energy, most likely, given the disruption in oil markets that has been running since February and pushing crude prices sharply higher. That pressure feeds into the headline number and into transport and food costs with a lag. It also means the headline could move again on developments that have nothing to do with domestic demand.
Does this affect interest rates?
It informs the discussion without settling it. A softer reading strengthens the case for easing, and a rate that remains well above target argues for patience. The Fed weighs employment alongside prices, and one month of data below consensus is unlikely to be decisive on its own.
What should be watched?
The next two reports and whether revisions continue trending down. A single month of PCE inflation below forecast is a data point. Three consecutive months below forecast is a direction, and only the second changes anything.
