Here are the hidden flaws in Warsh’s new way of tracking inflation

Here are the hidden flaws in Warsh’s new way of tracking inflation Here are the hidden flaws in Warsh’s new way of tracking inflation Federal Reserve Chairman Kevin Warsh is eyeing up inflation diffusion indices. At his pivotal speech at Jackson Hole in August, Federal Reserve Chair Kevin Warsh revealed one method he uses to gauge underlying inflation. Over the past 12 months, 54% of goods and services in the PCE basket showed price increases above 3%,” said Warsh.

He noted that’s well below the post-pandemic high of 77% but above the level of 32% in the two decades that precedes the pandemic. Given that the Fed then went and lifted interest rates three weeks later, the data point clearly has some relevance.

For one, Warsh is treating each component equally, rather than weighting by share of nominal spending. Food, energy and core goods account for roughly 47% of the 199 components on an equal-weighted basis, but only about 32% after accounting for expenditure weights,” say the economists at the Japanese investment bank. Housing, by contrast, accounts for just 3% of the 199 categories despite its 16% weighting in consumption.

So Warsh is looking at a particularly volatile subset of inflation categories. The other issue is that, historically, it hasn’t been any better than core PCE inflation in identifying the trend. As the chart shows, the measures appear to be concurrent rather than lead core PCE price data.
