Does the breadth of price increases show inflation has returned to normal?
Core argument: 52% of price index components were rising at least 3% y/y as of July 2026, down from 73% at the peak but above the 2000–2020 average share of 32%.
Breadth measures seem to track actual inflation pretty well, both overall and within narrower aggregates such as supercore services. The picture looks a bit better when components are weighted by their shares of total spending. Over the past few years, the weighted share of components with price increases of at least 3% has been higher than the unweighted share, while the spending-weighted share of components with price increases of at least 4% (much less 5%) has been lower than the unweighted share. That makes the current situation look more like the inflation accelerations of 1968-1971, 1987-1989, 1999-2001, and 2006-2008, rather than 1973, 1979, or 2022.
