Congress Faces Deadlock as Government Shutdown Extends, Threatening Economic Impact

The ongoing government shutdown, potentially the longest in US history, is causing economic concerns, with estimates of a 0.1% to 0.2% weekly impact on GDP and fears of larger damage if mass layoffs occur. The shutdown is driven by a standoff over Obamacare subsidies and could extend into November, with possible triggers for resolution including airport disruptions or military pay issues. Polls show significant public concern about economic effects, but some analysts remain cautiously optimistic about long-term impacts.
