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

Kevin Warsh, a former Federal Reserve governor, has proposed an alternative approach to tracking inflation. Rather than relying on traditional core measures, which strip out volatile food and energy prices, his method aims to offer a cleaner read on underlying price trends. The appeal is intuitive: core inflation has long been criticized for sometimes masking real cost pressures felt by households.

However, economists at Nomura find that the new gauge does not deliver better predictive power than conventional core readings. In other words, the alternative may add complexity without improving the ability to forecast where inflation is heading—the very purpose such measures are meant to serve.

For markets, the takeaway is less about any single data release and more about how inflation is interpreted. If alternative measures gain traction, they could influence how investors and policymakers frame the inflation debate. For now, the evidence suggests traditional core readings remain a reliable reference point, and upcoming inflation prints will likely stay central to rate expectations.
