Kevin Warsh

On Friday, the Department of Justice announced it was dropping its investigation of the current Federal Reserve Chair Jerome Powell. Senator Thom Tillis was effectively blocking the nomination process from moving forward while the Department of Justice investigation of Powell was ongoing. With Friday’s announcement, the path forward for confirming Kevin Warsh as the next Chair of the Federal Reserve can proceed. Last week, Kevin Warsh appeared before the Senate Banking Committee, making a statement and taking questions from Senators. While much of the questioning was more politically driven than substantive with regards to how Warsh views the economy and how he may handle the position of Fed Chair, there were a few takeaways that provided some insight into his views and how he may like to steer the Fed going forward.

On measuring inflation

When discussing inflation and how he prefers to measure inflation, Warsh said that he prefers to look at “things that are called trimmed averages” because they “take out the tail-risks, all of the one-off items.” Currently, the preferred measure of inflation for the Fed is Core PCE, which essentially strips out the food and energy components from PCE. The theory is that food and energy are historically volatile (big swings both up and down). Removing those components reduces the short-term “noise” and provides a cleaner picture of longer-term inflation trends. A trimmed average differs from this calculation in that instead of eliminating the same two components (food and energy), it trims both the high and low outlier components for each reading. The components that are trimmed could vary from month-to-month. The idea is that any large swings from month to month are likely one-off items that are not indicative of a longer-term trend.

In the role of Fed Chair, Kevin Warsh would not have absolute authority to make changes at the Fed as he is only one voting member, albeit an important voting member. What might a shift towards a trimmed average measure of inflation look like? Conveniently, the Dallas Fed runs a trimmed mean PCE calculation that can provide some insight. The chart shows Headline, Core, and Trimmed Mean PCE over the past five years to provide some context on how they move and relate to each other.

One interesting takeaway from this chart is that trimmed mean PCE is considerably closer to the FOMC’s 2% inflation target than both Headline and Core measures. It is also trending lower, meaning that it is both closer to the target and still trending in the right direction. While Warsh did not provide much insight into what his potential policy decisions might be, his preference for a trimmed average measure means that he might view the FOMC as much closer to its inflation target than a Core PCE analysis might provide. Generally, lower inflation provides more flexibility for the FOMC to lower rates so if (and it is a big IF at this point) the benchmark shifted from Core PCE to some sort of trimmed measure, that could mean a more dovish FOMC in the current environment.
