The October 2025 core inflation reading of 0.20% MoM reflects a slowdown from the 0.30% pace recorded in September and August. Over the past 12 months, the average monthly core inflation rate stands near 0.21%, indicating a broadly stable but slightly easing inflation environment. This moderation comes amid persistent supply chain normalization and cautious consumer demand.

Drivers this month

• Shelter costs contributed approximately 0.18 percentage points, continuing to exert upward pressure.
• Used vehicle prices declined slightly, subtracting about 0.05 percentage points from the core inflation rate.
• Energy and food components remain excluded, focusing on underlying price trends.

Policy pulse

The 0.20% reading remains above the Federal Reserve’s long-term inflation target of 0.17% monthly (2% annualized), but the deceleration suggests easing price pressures. This may reduce urgency for aggressive rate hikes but keeps the door open for a cautious approach.

Market lens

Immediate reaction: The US dollar index (USD) strengthened by 0.15% within the first hour post-release, while 2-year Treasury yields edged down by 3 basis points, reflecting tempered rate hike expectations. Breakeven inflation rates for 5-year TIPS declined modestly, signaling slightly reduced inflation risk premiums.

Core inflation is a key macroeconomic indicator that strips out volatile food and energy prices to reveal underlying price trends. The October 2025 figure of 0.20% MoM aligns with moderate economic growth and steady labor market conditions. The US unemployment rate remains low at 3.70%, supporting wage growth but not accelerating inflation sharply.

Monetary policy & financial conditions

The Federal Reserve’s current policy stance features a federal funds rate near 5.25%, reflecting a tightening cycle aimed at curbing inflation. Financial conditions have tightened moderately, with credit spreads widening slightly and mortgage rates hovering around 7%. These factors contribute to dampening demand-driven inflation pressures.

Fiscal policy & government budget

Fiscal policy remains moderately expansionary, with the 2025 federal budget deficit projected at 5.10% of GDP. Infrastructure spending and social programs continue to support aggregate demand, but the impact on inflation is balanced by ongoing monetary restraint.

External shocks & geopolitical risks

Global supply chains have largely stabilized after recent disruptions. However, geopolitical tensions in Eastern Europe and East Asia pose upside risks to energy and commodity prices, which could indirectly influence core inflation if sustained.

Market lens

Immediate reaction: US Treasury yields on the 2-year note fell by 3 basis points, reflecting a mild easing of rate hike expectations. The USD strengthened slightly, while breakeven inflation rates for 5-year TIPS declined by 4 basis points, signaling reduced inflation risk perception.

Looking ahead, the core inflation trajectory will depend on several factors including labor market tightness, supply chain developments, and monetary policy adjustments. We outline three scenarios:

Bullish scenario (20% probability)

• Core inflation falls below 0.15% MoM in coming months due to easing wage pressures and improved supply chains.
• Fed signals a pause or rate cuts by mid-2026, supporting equity markets and consumer spending.

Base scenario (60% probability)

• Core inflation remains near 0.20% MoM, consistent with steady economic growth and moderate wage gains.
• Fed maintains current rates with gradual adjustments, balancing inflation control and growth.

Bearish scenario (20% probability)

• Core inflation accelerates above 0.30% MoM due to renewed supply shocks or wage spirals.
• Fed resumes aggressive rate hikes, risking recessionary pressures and market volatility.

Structural & long-run trends

Long-term inflation expectations remain anchored near 2%, supported by credible Fed policy and technological advances that enhance productivity. Demographic shifts and globalization continue to exert downward pressure on inflation, but climate-related disruptions and fiscal deficits pose structural inflation risks.

The October 2025 core inflation rate MoM reading of 0.20% signals a modest easing in price pressures after a summer peak. While inflation remains above the Fed’s target on a monthly basis, the trend suggests a plateauing that may allow for a more measured policy approach. Risks remain balanced between persistent inflation and potential economic slowdown. Market participants should monitor labor market data, supply chain signals, and geopolitical developments closely.

Key Markets Likely to React to Core Inflation Rate MoM

Core inflation data significantly influences interest rates, currency valuations, and equity markets. The following tradable symbols historically track or react to US core inflation movements:

• SPX – The S&P 500 index often reacts to inflation data through shifts in risk sentiment and earnings expectations.
• USDEUR – The USD/EUR currency pair is sensitive to Fed policy shifts driven by inflation trends.
• BTCUSD – Bitcoin’s price can reflect inflation hedge demand and risk appetite changes.
• TSLA – Tesla’s stock price is influenced by consumer demand and interest rate changes linked to inflation.
• USDCAD – The USD/CAD pair reacts to commodity price shifts and inflation expectations in North America.

Insight: Core Inflation Rate MoM vs. SPX Since 2020

Since 2020, the US Core Inflation Rate MoM and the S&P 500 index (SPX) have shown an inverse correlation during tightening cycles. Periods of rising core inflation often coincide with market volatility and downward pressure on SPX, as higher inflation triggers Fed rate hikes. Conversely, easing inflation supports equity gains. This dynamic underscores the importance of inflation data in shaping equity market trajectories.
