Kevin Warsh, President Donald Trump's nominee for Federal Reserve chair, expressed his preference for using a trimmed inflation gauge instead of the traditional core price index for personal consumption expenditures (core PCE) during his Senate hearing on Tuesday [1]. Warsh argued that trimmed averages, which remove extreme price shocks, provide a clearer picture of underlying inflation by excluding one-off changes due to factors like geopolitics or specific commodities such as beef [1].
Bank of America economist Aditya Bhave noted that, under Warsh's preferred trimmed method, the 12-month inflation gauge would have a mean of 2.3% and a median of 2.8% as of February, compared to the core PCE's 3% reading [1]. Warsh described the current trend in inflation as 'quite favorable' during his testimony [1]. However, Bhave cautioned that switching to a trimmed gauge could inadvertently make energy and food prices more influential in Fed policy, as less extreme but still significant price spikes might not be excluded, potentially resulting in higher inflation readings than the core PCE [1].
Bank of America's data showed that in 2019 and 2020, the trimmed-median inflation gauge was higher than the core PCE, which would have encouraged a more hawkish stance from the Fed if used as the primary measure [1]. Bhave emphasized that if trimmed inflation outpaces core PCE in the future, Warsh would need to remain consistent with his preferred metric to preserve Fed credibility and avoid the appearance of cherry-picking data [1].
During the hearing, Warsh faced criticism from some who suggested he might align Fed policy with President Trump's preferences rather than economic fundamentals. Warsh denied that he would lower interest rates solely at Trump's request and faced rigorous questioning regarding his independence and qualifications [1].
CONCLUSION
Kevin Warsh's advocacy for a trimmed inflation gauge has sparked debate over its potential impact on Federal Reserve policy, with Bank of America highlighting both the benefits and risks of such a shift. While Warsh asserts the approach offers a more accurate view of underlying inflation, analysts warn it could lead to higher inflation readings and a more hawkish policy stance in certain environments. The market is watching closely for any changes in the Fed's inflation measurement strategy.
