Accounting for Chaos: The Policy Friction Behind America’s Q4 Slump
The most arresting number in America’s fourth-quarter slowdown was not the growth rate. It was the payroll count.
When output expanded at an annualised 1.4 per cent in the final three months of 2025, down from 4.4 per cent in the third quarter, the headline suggested a sharp loss of momentum. In reality, much of the deceleration was mechanical. A 43-day partial federal government shutdown, from 1 October to 12 November, forced roughly 650,000 federal employees into furlough while another 600,000 were required to work without immediate pay.
In the national accounts, public-sector output is largely recorded through the labour services provided by government employees. When those hours disappear, measured output falls automatically. Federal activity contracted at a 16.6 per cent annualised rate in the quarter, subtracting around one percentage point from overall GDP growth. What looked like broad economic weakness was, in large part, an accounting reflection of political paralysis.
The income shock was immediate. By mid-November, an estimated $16bn in wages had been withheld. Although back pay was eventually guaranteed, the interruption in liquidity curtailed discretionary spending in regions with a heavy federal presence. Restaurants near government offices emptied. Contractors delayed hiring. The drag was concentrated but visible.
Yet the shutdown alone does not explain the quarter’s softness. At the same time, America’s external imbalance widened to historic levels. The December monthly trade deficit exceeded $70bn. For the full year, the combined goods and services shortfall approached $900bn. More striking still was the goods deficit alone, which surpassed $1.2tn — the largest on record.
That distinction is crucial. The United States runs a surplus in certain high-value services, including finance and intellectual property. But the merchandise gap continues to widen even under an aggressive tariff regime intended to narrow it. The country is importing more physical goods than ever despite protectionist policy.
In GDP accounting, exports add to growth while imports are subtracted to avoid counting foreign output as domestic. When imports rise faster than exports, the trade balance turns negative and weighs on measured GDP. That dynamic was evident in the fourth quarter. Businesses had spent much of 2025 front-loading orders ahead of tariff increases. By year-end, inventories were being drawn down. Imports remained elevated while exports softened, reflecting weaker global demand and a firm dollar. The widening goods deficit therefore amplified the slowdown.
Tariffs added distortion without resolving the imbalance. Higher effective rates lifted the cost of consumer goods and intermediate inputs, contributing to price pressures in sectors such as autos and apparel. Yet they largely reshuffled trade flows rather than shrinking the aggregate gap.
Strip away government outlays and volatile inventories, and the private sector appears more stable than the headline suggests. Business investment, particularly in equipment and intellectual property linked to artificial intelligence, held up better than expected. The economy absorbed a self-inflicted shock rather than succumbing to recession.
The fourth quarter of 2025 reads less like a conventional downturn than a policy-induced bypass. Output slowed not because private demand collapsed, but because the state temporarily withdrew its own labour and the external sector deteriorated simultaneously. Growth will likely rebound as federal hours are restored and back pay circulates.
The deeper signal lies in the external accounts. A goods deficit exceeding $1.2tn reflects a structural imbalance between domestic consumption and tradable production, reinforced by a strong dollar and persistent fiscal deficits. Political turbulence may support the currency in the short term as global capital seeks safety. Yet that very strength suppresses export competitiveness and perpetuates the merchandise gap.
The United States can sustain large deficits so long as the world is willing to finance them. The fourth quarter suggests that willingness increasingly rests on confidence rather than inevitability. Growth will recover. The more delicate question is how long credibility remains unquestioned.
