Looking at the annualized monthly CPI inflation rate, March looks like an outlier: April inflation is up (again). The overall CPI rose from -0.6% in March to 2.68% in April; excluding the volatile food and energy components, core CPI inflation popped up from 0.68% to 2.88%. Nonetheless, the annual inflation rate fell slightly from 2.41% to 2.33% (overall CPI) or from 2.81% to 2.78% (core CPI). The decline in the annual inflation rate reflects the observaton that the monthly inflation rate for April 2024 exceeded that for April 2025.
Our trend measures of CPI inflation also rose: from 2.21% in March to 2.37% in April for overall CPI inflation, and from 2.55% to 2.66% for core CPI inflation. Regular readers will remember that our trend measure of inflation sees through the blips in the monthly inflation rate while also being more responsive to underlying changes in trend than the annual inflation rate.
We pay attention to CPI inflation because it tends to move together with PCE inflation (the Fed’s preferred measure) which will be released in a couple of weeks. The tick up in April’s CPI inflation suggests that we may see a similar increase in April’s PCE inflation. The prospects for the FOMC cutting interest rates remains dim.
