US Business Activity Hits 6-Month Low in December: Economic Slowdown Signals Caution for 2026

The slowdown spans both manufacturing and services sectors, marking a sharp deceleration from the robust growth experienced earlier in the year and raising concerns about economic momentum entering 2026. U.S. business activity growth hits 6-month low in December The S&P Global Flash PMI Deterioration S&P Global’s preliminary Composite Purchasing Managers’ Index (PMI), a key gauge of business health across the economy, dropped to 53.0 in December from a final reading of 54.2 in November, marking the sharpest monthly decline in recent months. While values above 50 still indicate expansion, the trajectory is deeply concerning for economic outlook. “The flash PMI data for December indicate that the recent economic growth surge is losing steam,” noted Chris Williamson, chief economist at S&P Global Intelligence. “With new sales growth diminishing sharply, especially ahead of the holiday season, economic activity may further weaken as we approach 2026.” New Orders Collapse to 20-Month Low The most alarming headline in the data is the smallest increase in new business inflows in 20 months, marking a dramatic slowdown in demand across the economy. This metric is particularly troubling because order flows typically lead hiring decisions and capital expenditure plans by 4-6 weeks. Manufacturing new orders experienced their first decline in a year, signaling that the sector faces structural headwinds rather than temporary cyclical weakness. The manufacturing PMI index fell to 51.8: the lowest since July: down from 52.2 in November, falling below the 52.4 median forecast from economists. Services activity, which represents two-thirds of U.S. economic output, declined to 52.9 in December, marking a six-month low: down sharply from 54.1 in November and well below the expected 53.5. This is the sector that has carried the economy through much of 2025, so weakness here signals broad-based deceleration. What’s Behind the Slowdown? The Trump Factor The deceleration cannot be divorced from the policy environment created since President Donald Trump returned to the White House in January 2025. Multiple headwinds have accumulated throughout the year: Tariff Uncertainty: Trump’s aggressive tariff agenda has created an unprecedented level of pricing and competitive uncertainty. Companies are uncertain about input costs, demand patterns, and the duration of tariff regimes, causing them to pull back on hiring and capital investment. Immigration Restrictions: Tighter immigration policies have exacerbated labor market constraints and reduced workforce growth, particularly in lower-wage industries dependent on immigrant workers. Government Shutdown: An unprecedented federal government shutdown in October-November 2025 halted crucial economic data releases and created operational disruption across government-dependent sectors. Volatile GDP Path: The U.S. economy contracted in Q1 2025 as companies rushed imports to avoid anticipated tariffs, followed by a rebound in Q2 as those trends reversed. Q3 growth exceeded 3% annualized before the shutdown, but the underlying trajectory has been erratic. Labor Market Under Strain The PMI data on employment reveals a deeply constrained hiring environment. S&P Global noted that job growth was often hindered by worries regarding costs, weak demand, and uncertainty about the economic forecast. “Some companies also reported ongoing labor shortages,” indicating that the slowdown is not due to an abundance of workers but rather a reluctance to hire despite continued labor supply constraints. This suggests the weakness is demand-driven, not supply-driven: a more pessimistic sign for economic resilience. This finding aligns with broader labor market data: U.S. unemployment rose to 4.6% in November, a four-year high, with job growth in November falling short of expectations. The combination of falling hiring and rising unemployment is particularly troubling in a late-cycle economy. Input Cost Inflation: The Fed’s Headache While demand is weakening, the gauge of input prices from S&P surged to its highest level in nearly three years, driven by a spike in costs reported by service providers. This stagflationary dynamic: weak demand combined with rising costs: presents a policy dilemma for Federal Reserve officials. Higher input costs suggest that any inflation decline achieved in 2025 may reverse, particularly if companies attempt to preserve margins amid pricing pressure. This could complicate Fed decisions on rate cuts, especially if demand weakness is temporary rather than structural. What Could Come Next The data paints a picture of an economy losing momentum at a critical juncture. With holiday shopping already underway and year-end closings upon us, the December flash PMI likely reflects pre-holiday caution rather than robust consumer demand. However, the one-month lag in PMI data means Q4 GDP figures may surprise to the downside. Fed Implications: The combination of weakening growth and rising input costs makes the Federal Reserve’s task exceptionally difficult. Recent inflation data showed core CPI moderation, potentially justifying rate cuts, but business-level input cost pressures could signal inflation persistence that justifies holding rates steady or even raising them. 2026 Outlook: Should the current slowdown persist into 2026: a significant risk given policy uncertainty around tariffs, trade negotiations with China, and potential additional regulatory changes: the economy could face outright contraction risk. Conversely, if trade negotiations reach resolution and policy clarity emerges, the economy could rebound sharply given the underlying strength of the labor market and consumer balance sheets. Key Takeaway The United States economy entered December 2025 on weakening footing, with business activity expansion hitting its slowest pace in six months. The collapse in new orders, widespread hesitation on hiring, and rising input costs create a complex backdrop where neither growth optimists nor recession pessimists can claim complete vindication. The coming weeks of data will be crucial in determining whether this slowdown is cyclical or signals structural challenges for 2026.
