US Bank September Outlook: Economy on Firm Footing in Q4, AI Investment Maintains Dominance, Labour Market Loosening Gradually
US Bank's September Monthly Outlook finds the US economy on firm footing heading into Q4 — AI investment still dominant, the labour market loosening gradually, and energy independence providing continued protection from the Middle East shock.
According to US Bank's Monthly Economic Outlook for September 2026, the US economy is on firm footing heading into Q4 2026, with the BEA's Q2 third estimate revision to 1.7% confirming the private sector strength that underlies a headline figure that had been suppressed by the government spending reversal and import surge. US Bank maintains its assessment that the US is executing a successful growth transition from consumption-led to investment-led expansion, with AI capital expenditure the primary incremental driver and energy independence the primary structural protection against the same geopolitical shock that is constraining European economic performance.
AI investment continues to exceed expectations in US Bank's September assessment. The scale of data centre construction, semiconductor equipment procurement, and AI software infrastructure investment being executed across the US economy has been consistently above forecast, with each quarterly data release showing that the AI capital expenditure cycle is maintaining momentum rather than moderating. US Bank notes that this investment is increasingly generating productivity benefits that are beginning to appear in service sector output-per-hour data, providing an early empirical signal that the expected productivity payoff from AI investment is beginning to materialise in the data.
The labour market is loosening gradually but from a position of exceptional tightness. Hiring intentions have moderated, job posting volumes have declined from their 2022-2024 peak, and wage growth has slowed from its prior exceptional pace. However, layoff rates remain historically low — the primary indicator that the labour market's moderation is a normalisation from unprecedented tightness rather than a deterioration toward weakness. The combination of moderating wages and stable employment provides the conditions for a gradual easing of the inflation pressure that has kept the Federal Reserve's policy rate elevated.
The Federal Reserve's September 2026 meeting — at which the FOMC left rates unchanged but acknowledged the gradually improving inflation picture — reinforces US Bank's view that the US is managing a soft landing: slowing growth to a sustainable pace without triggering the employment deterioration that would indicate a harder economic adjustment. US Bank projects US GDP growth continuing near its long-run potential pace of approximately 2% through Q4 2026 and into 2027, with the Federal Reserve beginning a cautious easing cycle in early 2027.
For international businesses, US Bank's September assessment of the US economy provides a consistent and reassuring picture of the world's largest market: growing at a sustainable pace, led by AI investment that is creating broad demand across technology, construction, logistics, and professional services, and insulated from the Middle East energy shock by domestic energy production. The US market in Q4 2026 offers both the demand volumes and the demand quality that make it a priority market for businesses with the capability to serve it.
