Fed’s Waller returns to transitory inflation view as core PCE falls to 2.6% in mid-2025, signalling potential rate cuts

In the evolving landscape of monetary policy, the notion of transitory inflation has resurfaced as a pivotal theme among Federal Reserve officials, signalling a potential shift in how policymakers view persistent price pressures amid economic uncertainties. As of late August 2025, remarks from key Fed figures suggest a renewed confidence that certain inflationary spikes, particularly those linked to external factors like tariffs, may prove short-lived rather than entrenched, influencing expectations for interest rate adjustments and broader market strategies.

The Resurgence of Transitory Inflation Narratives

The concept of transitory inflation—price increases deemed temporary and unlikely to require aggressive policy responses—gained notoriety during the post-pandemic recovery. Initially dismissed as overly optimistic when inflation surged beyond expectations in 2021 and 2022, it is now being revisited in light of new economic dynamics. Federal Reserve Governor Christopher Waller’s recent comments underscore this pivot, framing current inflationary risks as fleeting, especially when excluding one-off disruptions such as trade tariffs. This perspective aligns with broader Fed communications, where officials anticipate that underlying inflation metrics, stripped of these temporary effects, remain close to the 2% target.

Historical context illuminates this stance. In 2021, the Fed labelled inflation as transitory, attributing it to supply chain bottlenecks and pent-up demand from Covid-19 lockdowns. By 2022, as consumer prices climbed to multi-decade highs, this view was critiqued for underestimating persistence, leading to a series of rapid rate hikes. Fast-forward to 2025, and the narrative appears more nuanced. With core personal consumption expenditures (PCE) inflation hovering around 2.6% in mid-2025—down from peaks above 5% in prior years—the Fed seems emboldened to differentiate between structural and ephemeral drivers.

Analysts point to several factors bolstering this transitory outlook. First, labour market softening has reduced wage-driven inflationary pressures. Job openings have declined steadily since early 2024, with the unemployment rate edging up to 4.1% by July 2025, according to Bureau of Labor Statistics data. This weakening demand for labour mitigates the risk of a wage-price spiral, allowing the Fed to prioritise employment goals without immediate inflation fears. Second, global supply chains have stabilised post-pandemic, with commodity prices like oil stabilising below $80 per barrel through much of 2025, easing input costs for businesses.

Impact of Tariffs on Inflation Dynamics

A critical element in the transitory debate is the role of tariffs. Proposed or implemented trade barriers, averaging around 25% on certain imports, could temporarily elevate import prices, potentially pushing headline inflation towards 5% if sustained. However, Fed projections, as outlined in the March 2025 Summary of Economic Projections, anticipate these effects to dissipate within a year, reverting inflation to a 2.8% peak before declining. This echoes sentiments from the Federal Open Market Committee (FOMC) minutes of July 2025, which highlighted that tariff-induced price hikes are unlikely to embed into core inflation measures.

To quantify this, consider a breakdown of inflation components. The Consumer Price Index (CPI) can be segmented into flexible and sticky price baskets, as explored in a 2025 Federal Reserve Bank of Boston brief. Flexible prices, encompassing goods like food and energy that adjust frequently, have shown volatility but quick reversion to means. Sticky prices, such as services and rents, adjust more slowly but have trended downward since 2023. Excluding tariff impacts, underlying inflation in the flexible sector aligns closely with the 2% target, supporting the transitory thesis.

This table, derived from historical Fed data up to mid-2025, illustrates the deceleration across metrics, reinforcing why officials might lean towards a transitory label for new pressures.

Policy Implications and Market Reactions

If inflation is indeed transitory, the Fed’s path forward could involve measured rate cuts to support growth without reigniting price pressures. In his July 2025 speech, Chair Jerome Powell cautioned that while inflation may tick higher due to supply shocks, the base case remains short-lived effects. Market sentiment, as gauged by CME FedWatch Tool readings in August 2025, prices in a 75% probability of a 25 basis point cut at the September meeting, reflecting investor alignment with this view.

From an investor perspective, this narrative carries mixed implications. Equity markets, particularly in sectors sensitive to interest rates like technology and real estate, could benefit from looser policy. The S&P 500, having rallied 15% year-to-date through July 2025 on easing inflation fears, might extend gains if transitory proves accurate. Conversely, fixed income investors face risks; Treasury yields, with the 10-year note around 4.2% in mid-2025, could compress further, squeezing returns.

However, scepticism persists. Critics argue that repeated underestimation of inflation’s staying power—as seen in 2021—could erode Fed credibility. A March 2025 CNBC report noted that while the Fed expects tariffs to be transitory, historical episodes like the 2018-2019 trade wars saw inflation linger longer than anticipated. Analyst-led models, such as those from Goldman Sachs, forecast a modest uptick in 2025 CPI to 3.1%, but warn of stagflation risks if growth falters alongside persistent prices.

Risks and Forward-Looking Scenarios

Looking ahead, several scenarios could test the transitory hypothesis. A model-based forecast from the Federal Reserve Bank of New York’s DSGE framework, updated in Q2 2025, projects inflation at 2.4% by end-2026 assuming no major shocks, but rises to 3.5% under prolonged tariff regimes. Downside risks to the labour market, with job growth averaging 150,000 per month in 2025 versus 250,000 in 2024, heighten recession probabilities to 20%, per JPMorgan estimates.

• Optimistic Case: Transitory inflation allows for three to five rate cuts in 2025-2026, boosting corporate earnings and equity valuations.
• Pessimistic Case: If tariffs embed into wage expectations, inflation could average 4% through 2026, forcing the Fed to pause cuts and risking a policy error.
• Balanced View: With the policy rate moderately restrictive at 1.25-1.50 percentage points above neutral (estimated at 3%), the Fed has room to manoeuvre.

Investor sentiment, drawn from verified sources like the AAII survey in August 2025, shows 45% bullish on stocks amid cooling inflation, up from 35% earlier in the year. Yet, this optimism is tempered by concerns over geopolitical tensions and fiscal deficits.

Strategic Considerations for Investors

For portfolio construction, the transitory inflation theme suggests tilting towards assets that perform in disinflationary environments. Diversified bonds, with yields above inflation forecasts, offer income stability. Commodities, historically a hedge against persistent inflation, may underperform if pressures fade. Equity strategies could favour quality stocks with pricing power, resilient to temporary cost spikes.

In summary, the Fed’s embrace of transitory inflation in 2025 reflects a data-driven optimism, but one shadowed by past missteps. Investors would do well to monitor incoming data—particularly labour and trade metrics—for signs that this narrative holds, adapting strategies to balance growth opportunities with inflation risks. Dry humour aside, if history is any guide, labelling inflation as transitory might just be the Fed’s way of saying ‘this time it’s different’—until it isn’t.
