The North American economy’s year-over-year GDP growth rate for September 2025 came in at 1.60%, well below the consensus estimate of 4.30% and down from 2.80% in June 2025. This represents the slowest pace since December 2023’s 7.20% peak, marking a significant deceleration over the past nine months.

Drivers this month

• Consumer spending growth softened amid rising borrowing costs.
• Manufacturing output contracted slightly, reflecting global supply chain disruptions.
• Residential investment declined due to higher mortgage rates.

Policy pulse

The 1.60% growth figure sits well below the central bank’s inflation-target-compatible growth range of 2.50% to 3.50%, suggesting that monetary tightening is weighing on economic activity. The Federal Reserve and Bank of Canada have maintained restrictive policy stances to combat inflation, which is now moderating but still above target.

Market lens

Immediate reaction: The US dollar index (DXY) strengthened 0.30% within the first hour post-release, reflecting safe-haven demand amid growth concerns. Short-term Treasury yields rose modestly, pricing in a slower growth trajectory but persistent inflation risks.

Core macroeconomic indicators confirm the growth slowdown. Inflation remains sticky at around 3.80% YoY, down from 5.10% a year ago but above the 2% target. Unemployment rates have edged up slightly to 4.70%, signaling some labor market softening. Consumer confidence indices have dipped to 90, below the 12-month average of 95.

Monetary Policy & Financial Conditions

Central banks in North America have kept policy rates elevated near 5.25%, with forward guidance emphasizing data dependency. Financial conditions have tightened, with credit spreads widening by 15 basis points since June 2025. Mortgage rates have climbed above 7%, dampening housing demand.

Fiscal Policy & Government Budget

Fiscal stimulus has waned, with government budgets moving toward consolidation. The latest budget reports a deficit reduction target of 1.50% of GDP, down from 3.20% last year. Infrastructure spending continues but at a slower pace, limiting fiscal support to growth.

Market lens

Immediate reaction: The US Treasury 2-year yield rose 12 basis points, reflecting increased expectations of prolonged restrictive policy. The Canadian dollar weakened 0.40% against the US dollar, mirroring growth concerns and divergent monetary policy outlooks.

Looking ahead, three scenarios emerge for North America’s GDP growth trajectory:

• Bullish (20% probability): Inflation eases faster than expected, allowing monetary policy to loosen by mid-2026. Growth rebounds to 3.50% YoY by Q4 2026.
• Base (55% probability): Growth remains subdued around 1.50%-2.00% through 2026, with inflation gradually approaching target and policy rates steady.
• Bearish (25% probability): External shocks, including geopolitical tensions and commodity price spikes, trigger recessionary pressures. Growth falls below 1.00% YoY, with unemployment rising above 6%.

External Shocks & Geopolitical Risks

Heightened geopolitical tensions in Eastern Europe and Asia continue to disrupt supply chains and energy markets. Commodity price volatility, especially in oil and metals, poses inflationary risks that could derail the base case.

Structural & Long-Run Trends

Demographic shifts and productivity challenges weigh on potential growth. Automation and green energy investments offer long-term upside but have yet to offset cyclical headwinds fully.

North America’s GDP growth rate YoY at 1.60% signals a clear slowdown from recent years’ robust expansion. The data from the Sigmanomics database underscore the impact of tight monetary policy, fading fiscal stimulus, and external uncertainties. While inflation pressures are easing, growth remains fragile and vulnerable to shocks.

Policymakers face a delicate balance between sustaining growth and anchoring inflation expectations. Financial markets are pricing in this uncertainty, with volatility likely to persist. Investors and businesses should prepare for a cautious environment, with opportunities tied to structural shifts and policy developments.
