The Core PCE price index, the Federal Reserve’s preferred inflation gauge, recorded a 0.20% MoM increase in September 2025. This figure aligns with the prior month’s pace and remains below the 12-month average of approximately 0.25% observed over the past year. The steady inflation rate suggests that underlying price pressures are neither accelerating nor decelerating sharply, signaling a cautious but stable inflation environment.

Drivers this month

• Shelter costs contributed roughly 0.18 percentage points to the MoM increase, consistent with ongoing housing market tightness.
• Used vehicle prices exerted a mild downward drag of -0.05 percentage points, reflecting easing supply chain constraints.
• Services excluding shelter remained steady, supporting the overall core inflation stability.

Policy pulse

The 0.20% MoM Core PCE reading remains above the Fed’s long-run target of 2% annualized inflation but shows no signs of runaway price pressures. This steady pace supports the Federal Reserve’s current stance of cautious monetary tightening, with the central bank likely to maintain rates at restrictive levels to anchor inflation expectations.

Market lens

Immediate reaction: US Treasury yields on the 2-year note edged up by 3 basis points, while the USD index strengthened by 0.15% in the hour following the release. Breakeven inflation rates held steady, reflecting market confidence in the Fed’s inflation control measures.

Core macroeconomic indicators continue to paint a mixed but resilient picture. The US labor market remains tight, with unemployment steady near 3.80%, supporting wage growth that feeds into inflation. Consumer spending growth has moderated but remains positive, underpinning demand-driven price pressures. Meanwhile, producer price inflation has shown signs of easing, suggesting some relief in input costs.

Monetary policy & financial conditions

The Federal Reserve’s policy rate currently sits at 5.25%, reflecting a series of hikes aimed at taming inflation. Financial conditions have tightened moderately, with credit spreads widening slightly and mortgage rates hovering near 7%. These conditions are expected to weigh on housing demand and broader consumption in coming quarters.

Fiscal policy & government budget

Fiscal policy remains moderately expansionary, with the government running a deficit near 5% of GDP. Recent infrastructure spending and social programs provide some stimulus, but rising debt service costs could constrain future fiscal flexibility. The interplay between fiscal support and monetary tightening will be critical in shaping inflation trajectories.

External shocks & geopolitical risks

Global supply chain disruptions have largely abated, but geopolitical tensions in Eastern Europe and East Asia pose upside risks to energy and commodity prices. Any escalation could feed into headline inflation, complicating the Fed’s inflation targeting efforts.

Market lens

Immediate reaction: Following the release, the S&P 500 futures dipped 0.10%, while the USD/JPY currency pair appreciated 0.20%, signaling cautious optimism about the Fed’s inflation control without triggering fears of aggressive tightening.

Looking ahead, inflation dynamics will hinge on several key factors. The labor market’s tightness and wage growth could sustain core inflation near current levels. However, easing supply chain pressures and moderating consumer demand may temper price increases.

Scenario analysis

• Bullish (20% probability): Inflation moderates to 0.10% MoM by year-end, enabling the Fed to pause rate hikes and potentially pivot to easing in mid-2026.
• Base case (60% probability): Core PCE remains around 0.20% MoM, with the Fed maintaining restrictive policy through 2026 to gradually bring inflation to target.
• Bearish (20% probability): Inflation accelerates above 0.30% MoM due to wage pressures or external shocks, forcing the Fed into more aggressive tightening and risking recession.

Structural & long-run trends

Longer-term inflation expectations remain anchored near 2%, supported by credible Fed policy and evolving supply chain resilience. Demographic shifts and technological advances may exert downward pressure on inflation over the next decade, but cyclical factors dominate near-term outcomes.

The September 2025 Core PCE price index MoM reading of 0.20% underscores a steady inflation environment. While not signaling immediate relief, it suggests inflation is contained enough to avoid drastic policy shifts. Markets have responded with measured optimism, reflecting confidence in the Fed’s calibrated approach. However, vigilance remains essential amid geopolitical uncertainties and evolving fiscal dynamics.

Investors and policymakers should monitor shelter inflation and wage trends closely, as these remain key inflation drivers. The balance of risks points to a gradual path toward the Fed’s 2% target, but surprises on either side could prompt rapid adjustments.

Insight: Core PCE vs. SPX Since 2020

Since 2020, the Core PCE price index MoM and the S&P 500 (SPX) have shown an inverse relationship during inflation spikes. For example, the 0.40% Core PCE increase in March 2025 coincided with a 3% drop in SPX over the following week. Conversely, periods of easing inflation, such as the 0.10% reading in May 2025, supported equity rallies. This dynamic underscores the sensitivity of equities to inflation trends and Fed policy expectations.
