Federal Reserve Chair Kevin Warsh appears to be nudging the central bank toward prioritizing measures of underlying price pressures instead of anchoring policy explicitly to the Fed's traditional 2% annual inflation target in the Personal Consumption Expenditures (PCE) price index, a Yardeni Research note said.
Unlike former Chair Jerome Powell, who routinely linked the Fed's inflation goal to headline PCE readings, Warsh has stopped short of declaring the PCE price index the definitive metric for price stability. His recent public statements place more weight on persistent, broad-based inflation trends than on temporary swings in specific price categories.
In congressional testimony, Warsh argued that one-off price jumps should not automatically prompt a monetary policy response when they are later offset by improvements in supply. He described the consumer and producer price indexes as imperfect proxies for underlying inflation, and he signaled a preference for measures that strip out transitory shocks.
Yardeni Research characterized this stance as a notable departure from the Federal Reserve's prior framework, where indicators such as core, median and trimmed-mean inflation mainly served as inputs to forecast headline PCE rather than as policy targets in their own right. The research firm warned that elevating these alternate gauges to the status of policy benchmarks could reduce the transparency of the Fed's inflation objective for the public.
Warsh has established a task force to determine which measure of underlying inflation is most appropriate for policymakers to use. Yardeni identified several leading contenders the task force may consider: the Dallas Fed's Trimmed Mean PCE inflation gauge, which removes extreme price movements across categories; unit labour costs; and so-called "supercore" inflation, defined as services inflation excluding housing and energy.
According to Yardeni, supercore inflation may more clearly reflect price pressures stemming from domestic demand and labour-market conditions while excluding temporary disturbances arising from tariffs, supply-chain problems and movements in goods prices. The firm noted that because monetary policy has more direct influence over wages, hiring and overall demand than it does over commodity prices or supply constraints, supercore measures could provide a better indication of inflationary forces that interest-rate policy can affect.
Yardeni said the shift in emphasis implied by Warsh's remarks - and by the creation of the task force - represents a potential recalibration of how the Fed interprets inflation data. The research house flagged that making such alternative measures central to policy would change how clearly the Fed's inflation goal is communicated to the public.
