The US inflation rate MoM for October 2025 registered at 0.30%, down from 0.40% in September and below the 0.40% consensus estimate. This marks a slight deceleration but remains elevated relative to the subdued 12-month average of approximately 0.22%. Over the past ten months, inflation has fluctuated between -0.10% and 0.50%, reflecting ongoing volatility in price pressures.
Drivers this month

- Energy prices stabilized, subtracting about 0.05 percentage points from the headline figure.
- Used vehicle prices showed a modest decline, easing inflationary pressures by 0.03 percentage points.
Policy pulse
The 0.30% MoM inflation reading remains above the Federal Reserve’s preferred core inflation target of 0.20% monthly (equivalent to 2% annualized). This suggests that while inflation is moderating, price pressures are still persistent enough to keep monetary policy on a cautious footing. The Fed is likely to maintain a hawkish stance, balancing growth concerns with inflation containment.
Market lens
Immediate reaction: US Treasury 2-year yields rose by 5 basis points, reflecting increased expectations for sustained rate hikes. The USD strengthened modestly against the EUR and JPY, while breakeven inflation rates edged down slightly, signaling mixed market sentiment.
Inflation is a core macroeconomic indicator influencing growth, employment, and monetary policy. The October 2025 MoM inflation rate of 0.30% compares with a 12-month average of 0.22%, highlighting persistent but easing price pressures. Year-over-year inflation remains elevated near 3.80%, above the Fed’s 2% target.
Monetary policy & financial conditions
The Federal Reserve’s benchmark interest rate currently stands at 5.25%. The inflation print supports the Fed’s recent messaging that further rate hikes may be necessary, though the pace could slow. Financial conditions remain tight, with credit spreads slightly widened and volatility elevated in equity markets.
Fiscal policy & government budget
Fiscal stimulus has tapered, with the government budget deficit narrowing to 4.10% of GDP in Q3 2025. Reduced fiscal support limits demand-side inflationary pressures but also constrains growth. Infrastructure spending and targeted social programs continue to provide moderate economic support.
External shocks & geopolitical risks
Global supply chain disruptions have eased but remain a risk factor. Recent geopolitical tensions in Eastern Europe and the South China Sea pose potential threats to energy and commodity prices, which could feed into inflation volatility.
Drivers this month
- Shelter: 0.18 pp (steady rise)
- Energy: -0.05 pp (stabilization)
- Used vehicles: -0.03 pp (price declines)
- Food prices: 0.07 pp (moderate increase)
Policy pulse
The inflation rate remains above the Fed’s comfort zone, reinforcing expectations for a cautious approach to rate cuts. The central bank’s preferred core PCE inflation target of 2% annualized translates roughly to 0.17% monthly, underscoring that current inflation is still elevated.
Market lens
Immediate reaction: US 2-year Treasury yields increased by 5 basis points, reflecting hawkish sentiment. The USD index rose 0.30%, while breakeven inflation rates declined 2 basis points, indicating some market skepticism about sustained inflation pressures.
This chart highlights a trend of moderating inflation after mid-year peaks, with shelter costs as the main driver. The data suggest inflation is easing but remains above target, signaling ongoing challenges for policymakers balancing growth and price stability.
Looking ahead, inflation dynamics will depend on several factors, including monetary policy, fiscal stimulus, and external shocks. We outline three scenarios:
Bullish scenario (20% probability)
- Inflation falls below 0.20% MoM by Q1 2026 due to stronger productivity and supply chain normalization.
- Fed begins rate cuts in mid-2026, supporting growth and equity markets.
- Fiscal consolidation continues, reducing demand-side pressures.
Base scenario (55% probability)
- Inflation moderates gradually to 0.20-0.30% MoM through 2026.
- Fed maintains rates near current levels until mid-2026, then slowly eases.
- Geopolitical risks remain contained, with stable commodity prices.
Bearish scenario (25% probability)
- Inflation rebounds above 0.40% MoM due to renewed supply shocks or wage pressures.
- Fed tightens further, risking recession and market volatility.
- Fiscal stimulus increases amid political pressures, fueling demand.
Structural & long-run trends
Long-term inflation trends reflect demographic shifts, technological innovation, and globalization. Aging populations and slower productivity gains may keep inflation sticky. Meanwhile, digital transformation and automation could exert downward pressure on prices over the next decade.
The October 2025 US inflation rate MoM of 0.30% signals a modest easing but sustained price pressures. Monetary policy remains vigilant, balancing the risk of overtightening against persistent inflation. Fiscal policy is less stimulative, while external risks and market sentiment add complexity. Structural trends suggest inflation will moderate but not disappear, requiring careful policy calibration.

Key symbols to watch include SPY (US equities), USDEUR (USD/EUR forex pair), USDJPY (USD/JPY forex pair), BTCUSD (Bitcoin), and TLT (long-term US Treasury ETF).
