US BEA Adjusts PCE Calculation Method, May Core Inflation Expected to Be Revised Down by 13 Basis Points
N.R. Finch
The Bureau of Economic Analysis will change how it measures portfolio management fees inside core PCE starting in September. Bloomberg estimates the revision lowers May core PCE by 13 basis points — narrowing the gap with CPI and shifting the data foundation the Fed relies on for policy.
What exactly is changing?
BEA previously used the producer price index (PPI) for portfolio management services to deflate this spending category. The new method uses total industry hours worked (employment × average hours) as the real-output measure.
In plain terms = the old ruler tracked "how much did this service's price rise"; the new one tracks "how much labor did the industry put in." Different ruler, different reading.
The revision will restate data back to 2021.
How much does it move the inflation number?
May portfolio management fees drop from 21.6% year-on-year to 14.3%, cutting their contribution to core PCE from 37 basis points to 24.
This means → this single adjustment shaves roughly 13 basis points off the May core PCE annual rate.
This reflects a broader pattern: the recent run-up in portfolio management fees has been a key driver of core PCE staying above core CPI. The new method squeezes out that overshoot.
What happens to consumption and GDP?
May real personal consumption flips from −1.6% year-on-year to +4.8% — a full directional reversal.
In plain terms = same spending, different ruler. Consumers didn't change behavior; the statistical yardstick did.
GDP impact is modest: roughly +2 basis points for full-year 2025 and +9 basis points on the Q1 2026 annualized quarter-on-quarter rate.
What does this mean for the Fed?
Core PCE is the Fed's preferred inflation gauge. After the revision, it should track closer to core CPI, narrowing a persistent and unusual gap between the two.
This means → if the gap does close, the data case for "inflation is still sticky" weakens — one more argument on the dovish side of the ledger.
The key checkpoint: once BEA implements the change in September, does core PCE still run meaningfully above core CPI? If the gap disappears, policy judgments built on "PCE runs hot" will need revisiting.
