How does a US government shutdown effect the stock market?

Overall Market

• Shutdowns barely dent stocks—S&P 500 fell only ~2% on average during past standoffs.
• Example: 2013 shutdown (16 days)—S&P slipped ~3% during, then rallied +10% in the next 3 months.
• 2018–19 shutdown (35 days)—S&P gained +11% in the following month.
• Bottom line: short-term chop, then a rebound. Bigger drivers remain earnings and Fed policy.

Sectors & Assets

• Defense, healthcare, IT contractors risk delays in federal payments.
• Treasuries and gold usually catch a bid; bond yields slide.
• Dollar weakens as global investors side-eye U.S. dysfunction.
• Healthcare could take a hit if ACA credits lapse.

Economic Fallout

• Each week closed shaves ~0.1–0.2% off GDP, usually recouped later.
• Key data releases (jobs, inflation) get delayed, leaving the Fed and Wall Street flying blind.
• Long impasses hit confidence, chilling consumer spending and business hiring.
