New data from June suggests a significant deceleration in underlying inflationary pressures, with key "trimmed mean" measures indicating a trend back towards the Federal Reserve’s long-sought 2% target. This development arrives at a pivotal moment, as Federal Reserve Chairman Kevin Warsh has signaled an intention to re-examine the central bank’s approach to inflation metrics, potentially elevating the importance of these nuanced indicators. While the broad disinflationary trend offers a glimmer of hope for a potential soft landing, it is met with skepticism and outright dissent from some Fed officials, who argue that inflation remains uncomfortably high and warrants further action.

The Disinflationary Trend Takes Hold

June’s pricing data presented a compelling picture of receding inflationary pressures, particularly when viewed through the lens of trimmed mean measures. These specialized metrics, designed to filter out extreme price fluctuations that can distort headline figures, showed inflation reaching its lowest levels since the early part of the decade.

The Dallas Fed’s closely watched trimmed mean Personal Consumption Expenditures (PCE) price index, for instance, reported a striking one-month annualized rate of just 1.4% for June. This figure marks a substantial 1.3 percentage point drop from May’s reading and represents the lowest level recorded since November 2020. Even more significant for Fed policymakers, who prioritize longer-term trends, the 12-month trimmed mean PCE rate dipped to 2.2%. This decline of 0.2 percentage points from the previous month brought the annual measure to its lowest point since July 2021, placing it remarkably close to the Fed’s explicit 2% inflation objective.

Parallel data from the Cleveland Fed, which employs a "16% trimmed mean" using the Consumer Price Index (CPI) as its benchmark, reinforced this narrative. For June, the trimmed CPI registered 2.63%, which, on an unrounded basis, was its lowest reading since May 2021. This broad-based evidence of moderating price increases across different methodologies suggests that the underlying inflationary pulse in the U.S. economy is indeed weakening.

The backdrop to these trimmed mean figures includes the broader inflation gauges. The Commerce Department’s report on the overall PCE price index for June showed a 0.1% decline for the month, largely attributable to a sharp reduction in fuel costs. The core PCE, which strips out volatile food and energy prices and is the Fed’s preferred inflation metric, registered a modest 0.1% gain. On an annual basis, the all-items PCE rose by 3.7%, while core PCE increased by 3.3%. While these headline and core annual figures still sit above the Fed’s 2% target, the monthly deceleration, especially in the trimmed mean data, points towards a significant shift in momentum.

Chairman Warsh’s Strategic Reassessment

The timing of this disinflationary signal could not be more pertinent. Federal Reserve Chairman Kevin Warsh has recently articulated his intention to undertake a comprehensive re-examination of how the central bank assesses inflation and the specific data points it prioritizes. This initiative suggests a potential pivot in the Fed’s analytical framework, moving beyond a sole reliance on traditional core inflation measures to embrace a broader array of indicators, including those that offer a clearer signal of underlying price trends.

Economists are already anticipating the implications of Warsh’s new focus. Andrew Hollenhorst, an economist at Citigroup, commented in a recent note, "Trimmed mean data should also now fall closer to target-consistent rates." He further elaborated, "The fact that underlying inflation is still slowing toward target – as indicated by a broad set of indicators – is now even more relevant given Chair Warsh’s suggestion that he would analyze inflationary pressure by looking across a broad range of metrics." Hollenhorst’s analysis suggests that markets are likely to "price-out rate hikes in coming months on inflation data, and price-in cuts if the unemployment rate rises as we project," indicating a potential shift in monetary policy expectations.

Warsh’s commitment to re-evaluating inflation measurement comes after a prolonged period where inflation consistently ran above the Fed’s 2% target for over five years. This sustained overshoot has prompted an internal debate within the central bank about the efficacy of its current forecasting tools and its understanding of inflationary dynamics in a post-pandemic economy. By explicitly acknowledging the need to look "across a broad range of metrics," Warsh is signaling a more holistic and potentially more flexible approach to monetary policy in the years ahead.

Understanding Trimmed Mean Measures: A Deeper Dive

To appreciate the significance of these latest figures, it’s crucial to understand how trimmed mean inflation measures function. Unlike headline inflation, which can be heavily swayed by temporary spikes or dips in a few categories (e.g., energy prices, specific food items), or even core inflation which simply excludes food and energy, trimmed mean measures aim to capture the more persistent, broad-based inflation trend.

The Dallas Fed’s measure, for instance, operates by analyzing the individual price changes of components within the PCE price index. It then "trims" or excludes a significant portion of the most extreme price movements – specifically, it tosses out 24% of the lower-end price readings and 31% of the highest-end price readings. By eliminating these outliers, the Dallas Fed arrives at a "better midpoint" of where inflation truly lies, free from idiosyncratic shocks. This method helps to distinguish between temporary price volatility and genuine shifts in the underlying inflation rate.

Similarly, the Cleveland Fed’s "16% trimmed mean" CPI measure follows a comparable logic, though applied to the Consumer Price Index. It includes price changes that fall between the 8th and 92nd percentiles, effectively removing the most extreme 8% of price decreases and the most extreme 8% of price increases. Both approaches are designed to provide a cleaner signal of inflation by focusing on the typical or median price changes across the economy, rather than being distorted by a few volatile components.

While these measures offer a valuable perspective, they are not without their caveats. Lorie Logan, President of the Dallas Fed, whose institution oversees one of the primary trimmed mean gauges, has herself cautioned against over-interpreting these figures due to "compositional factors." Logan has highlighted that her researchers have found "that a change in the mix of price increases and decreases is causing the trimmed mean to drop too many increases right now. This effect likely makes the trimmed mean lower than the true inflation trend." This caution underscores the complexity of inflation measurement and the need for policymakers to consider a holistic view rather than relying on any single indicator.

Internal Dissent and Persistent Inflation Skepticism

Despite the encouraging signals from trimmed mean data, the Federal Open Market Committee (FOMC) remains deeply divided on the path forward. At its recent July meeting, the FOMC opted to keep its benchmark interest rate steady. However, this decision was not unanimous. Lorie Logan, President of the Dallas Fed, notably dissented, advocating for a quarter percentage point increase in interest rates.

Logan’s rationale for dissenting stemmed from her conviction that inflation continues to run above target and that the risks remain tilted to the upside. In a statement released shortly after the FOMC meeting, she articulated her concerns: "Even after accounting for productivity gains and temporary supply shocks, inflation appears to be trending toward the mid-2’s, not all the way to 2 percent, and the risks are to the upside." This perspective suggests that while inflation may be moderating, it is not decelerating fast enough or convincingly enough to reach the Fed’s target without further restrictive policy.

Logan was joined in her dissent by two other influential regional Presidents: Neel Kashkari of Minneapolis and Beth Hammack of Cleveland. Both echoed similar sentiments, expressing discomfort with the current level of inflation and arguing for immediate action rather than a wait-and-see approach. Their collective dissent underscores a significant faction within the Fed that perceives persistent inflationary threats, even as some measures suggest disinflation. These officials believe that waiting too long to act could entrench inflation expectations or allow underlying price pressures to reaccelerate, necessitating more aggressive and potentially disruptive tightening in the future.

Chairman Warsh himself, while acknowledging some potentially positive signs from production, voiced only "halting confidence" in the current trajectory of inflation. He emphatically stated, "Not one of my FOMC colleagues is under any illusion. We have begun a new chapter, and we understand that the five-plus years of inflation above target cannot be cured in nine weeks – or by a single month of modest price decreases." This statement highlights the cautious approach of the leadership, recognizing the long battle against entrenched inflation and the need for sustained evidence before declaring victory.

Market Reactions and Broader Implications

The financial markets reacted swiftly and decisively to the FOMC’s decision to hold rates steady, alongside the mixed signals from inflation data. Bond yields, particularly at the long end of the duration curve, surged following the meeting. This surge reflects investors’ attempts to price in future growth and inflation prospects. A rise in long-term yields can indicate concerns about future inflation eroding the value of fixed-income investments, or it can signal expectations of stronger economic growth that might warrant higher interest rates down the line. The uncertainty surrounding the Fed’s future path, especially with the internal dissents and Warsh’s stated re-evaluation, likely contributed to this market volatility.

The evolving inflation picture carries significant implications for various sectors of the economy. For consumers, a sustained trend of lower underlying inflation could translate into more stable prices for goods and services over time, alleviating the pressure on household budgets that has been building for years. For businesses, predictable and lower inflation can foster greater investment and planning certainty.

However, the persistent concerns from some Fed officials and the Chairman’s own cautious remarks suggest that the path to 2% inflation is not yet secure. Should inflation prove more sticky than the trimmed mean measures suggest, or if compositional factors indeed understate the true inflation trend, the Fed might be compelled to resume rate hikes later in the year, potentially impacting economic growth and employment. Conversely, if the disinflationary trend solidifies and the unemployment rate begins to rise as some economists project, the Fed could shift towards rate cuts, offering a significant boost to economic activity.

The next several months will be crucial in determining the true trajectory of inflation and the Fed’s ultimate policy response. All eyes will be on upcoming inflation reports, labor market data, and further communications from Chairman Warsh and other FOMC members as they navigate this complex and uncertain economic landscape. The debate between those who see clear progress towards the inflation target and those who fear lingering price pressures will continue to shape the central bank’s decisions and, by extension, the broader economy.
