U.S. Shutdown Threatens to Mute Strong Q3 Growth Momentum as Data Delays Cloud Outlook — Evening Brief – 10.14.25
The ongoing U.S. government shutdown is beginning to cast a shadow over what had been shaping up to be another quarter of solid economic expansion. While the most recent data available still point to a robust +2.4% annualized GDP gain for Q3, economists warn that the longer the shutdown drags on, the greater the uncertainty surrounding the accuracy and timeliness of those estimates.
The Bureau of Economic Analysis (BEA) is scheduled to release its initial estimate of third-quarter GDP on October 30, assuming the agency is open by then. However, each day of delay in data collection and reporting compounds the challenge of producing reliable figures.
Based on current forecasts, the U.S. economy likely expanded at a 2.4% annualized rate in Q3, according to consensus estimates compiled from private-sector models. While that marks a notable deceleration from Q2’s 3.8% surge, the data still suggest the economy remained resilient between July and September, driven by steady consumer spending, resilient business investment, and strong travel and services activity.
Recession risk remained low through the summer, with inflation continuing to moderate and labor markets cooling in an orderly fashion. Yet, the same cannot be said for the coming months. Early indicators point to momentum fading in Q4, particularly across regional economies already showing signs of contraction.
An analysis from Moody’s Analytics shows that a third of U.S. state economies are already contracting, and another 13% are “treading water.” The firm’s chief economist, Mark Zandi, warned that two of the nation’s largest economies—California and New York—are on the brink of contraction.
“Those two states are treading water. They’re big states, and if they go into the red, then that’ll probably take the national economy with them into recession,” Zandi said. Both states represent nearly 25% of total U.S. GDP, amplifying the potential national impact if growth there turns negative.
High-frequency indicators support this narrative of slowing but positive growth. The S&P U.S. Composite PMI, often used as a real-time GDP proxy, showed that September activity downshifted modestly but remained in expansion territory.
“Employment meanwhile barely rose, but confidence in the outlook strengthened noticeably. Cost pressures remained elevated, although inflation softened to a five-month low. A similar trend was seen for output charges,” the consultancy reported. The combination of cooling inflation and resilient optimism suggests the economy may still be threading a narrow path between growth and stagnation.
Economists estimate that each week of government shutdown trims U.S. GDP by roughly 0.1 to 0.2 percentage points. With the closure now entering its second week, the cumulative impact could soon start to erode the modest growth cushion built up earlier in the year.
If the shutdown persists through October, analysts warn the fourth-quarter GDP print could turn negative, reflecting lost federal payrolls, deferred spending, and disruptions to data-dependent private sector decision-making. “A multi-week shutdown would not just distort economic reporting—it would actively slow the economy itself,” one strategist at Morgan Stanley said.
