The US budget balance for November 2025 posted a deficit of -$284 billion, a sharp reversal from October’s $198 billion surplus. According to the Sigmanomics database, this deficit is the largest monthly shortfall since June 2025 (-$316 billion) and marks a significant deterioration compared to the average monthly deficit of -$157 billion over the past 12 months.

Drivers this month

• Increased federal spending on social programs and defense contributed approximately $120 billion to the deficit rise.
• Tax revenues fell by nearly 5% MoM, reflecting slower corporate earnings and softer individual income tax receipts.
• Interest payments on debt rose by $15 billion, driven by higher yields on US Treasury securities.

Policy pulse

The deficit spike complicates the Federal Reserve’s inflation-targeting efforts. While the Fed has maintained a cautious stance, fiscal expansion pressures risk overheating the economy. The budget swing suggests limited fiscal tightening despite calls for deficit reduction.

Market lens

Immediate reaction: The US dollar index (DXY) weakened 0.30% post-release, while 2-year Treasury yields rose 8 basis points, reflecting increased concerns over fiscal sustainability and inflationary pressures.

The budget deficit’s expansion coincides with mixed macroeconomic signals. GDP growth for Q3 2025 was revised upward to 2.10% annualized, but inflation remains sticky at 4.20% YoY, above the Fed’s 2% target. Unemployment held steady at 3.70%, near historic lows, supporting consumer spending but also wage pressures.

Monetary Policy & Financial Conditions

The Federal Reserve has kept the federal funds rate steady at 5.25%, balancing growth and inflation risks. Financial conditions tightened slightly, with credit spreads widening 12 basis points in November, reflecting cautious investor sentiment amid fiscal uncertainty.

Fiscal Policy & Government Budget

Fiscal policy remains expansionary. The November deficit contrasts with a brief surplus in October, highlighting volatility in government receipts and outlays. Year-to-date, the US budget deficit stands at approximately $1.20 trillion, 8% higher than the same period in 2024.

The chart reveals a pattern of sharp monthly fluctuations, with deficits peaking in March (-$307B), June (-$316B), and September (-$345B). Surpluses in May (+$258B) and October (+$198B) appear as temporary reprieves rather than sustained fiscal consolidation.

Market lens

Immediate reaction: US Treasury 10-year yields rose 10 basis points, reflecting investor concerns about rising government borrowing needs. The S&P 500 index dipped 0.50%, indicating risk-off sentiment.

Looking ahead, the US budget balance trajectory depends on several factors. The baseline scenario projects a continued deficit averaging -$250 billion monthly through Q1 2026, driven by sustained spending and moderate revenue growth. This scenario carries a 55% probability.

Bullish scenario (25% probability)

• Stronger economic growth boosts tax revenues by 7% YoY.
• Targeted spending cuts reduce monthly deficits below -$150 billion.
• Monetary policy remains accommodative but vigilant.

Bearish scenario (20% probability)

• Economic slowdown depresses revenues by 5% YoY.
• Geopolitical tensions increase defense spending sharply.
• Rising interest rates push debt servicing costs higher.

Risks & Opportunities

Fiscal risks include political gridlock delaying budget reforms and external shocks disrupting trade. Opportunities lie in potential tax reforms and improved economic productivity. The Federal Reserve’s response will be critical in balancing inflation and growth amid fiscal uncertainty.

The November 2025 US budget balance highlights persistent fiscal challenges. The sharp deficit swing underscores volatility in government finances amid a complex macroeconomic backdrop. Policymakers face a delicate balancing act between supporting growth and ensuring long-term debt sustainability.

Structural deficits remain a concern, with the 12-month average deficit at -$157 billion signaling entrenched fiscal imbalances. External geopolitical risks and financial market volatility add layers of uncertainty. Close monitoring of budget trends and coordinated fiscal-monetary policy will be essential in 2026.
