Core PCE inflation report for May 2025: trending upwards

The one year percentage change for May’s core PCE report came in at 2.7%, which gives an idea of 1 year inflation centered on November 2024. The best forecast of inflation centered on May 2025 is the annualized six month percentage change, which was a slightly higher 2.9%. The probability that centered inflation has rose over the past 6 months is at 69%.

Inflation is somewhat elevated and probably increasing. The Fed Funds is at 4.3%: subtracting out 2.9% gives an estimated real rate of 1.4%. Since January 2000 that figure averaged at *negative* 0.1%, but during the 1990s it averaged + 3.9%. So the fed funds rate is little high for this century, but not anywhere near as tight as it was during the 1990s.


Review of Core PCE report for November, Released on Dec 20, 2024

With the next PCE report coming on Jan 31, 2025, I thought I would review the report released last month. The above graph is a little different than the last post as it only uses the latest revised data and doesn’t bother to dig out inflation rates as they were originally reported. Comparison of the red, green, and inchworm lines, as well as the purple probability line, with the last post shows that the effects of the approximation are more than trivial.

One year core PCE inflation came in at 2.8%: inflation over the past year gives us an idea of general price pressures as of 6 months ago, halfway through the time span. The annualized six month lag provides the best estimate of centered inflation as of November 2024: that was 2.4%, a little lower.

Price pressures eased: given historical experience we’d expect November’s centered inflation to come in lower than centered inflation in May (6 months prior) about 80% of the time.

The Federal Reserve has a long term target of 2.0% inflation: the latest report indicates steady progress towards that goal as of November 2024.
