How Stock Market Reacts to Government Shutdowns: Why History Says Don’t Panic

What the Numbers Actually Show

Government shutdowns make headlines and create anxiety. But the market data tells a different story.

Since 1980, the S&P 500 has posted gains one month after the start of every single government shutdown – a 100% success rate.

Markets focus on corporate earnings, economic growth, and interest rates, not temporary political gridlock. The four major shutdowns below show exactly how the S&P 500 has performed during each crisis.

A Brief History: Why Government Shutdowns Became Common

Government shutdowns are a uniquely American phenomenon. Before the early 1980s, federal agencies simply continued operating during funding gaps with minimal disruption, assuming Congress would pass appropriations bills shortly.

This changed following a series of legal opinions issued in 1980 and 1981 by Attorney General Benjamin Civiletti.

The Civiletti Doctrine:

Attorney General Benjamin Civiletti’s 1980-1981 legal opinions established that government agencies lack authority to continue operations during funding gaps under the Antideficiency Act. This interpretation transformed what had been minor administrative inconveniences into full government shutdowns requiring employee furloughs and service suspensions.

Following these opinions, funding gaps began triggering actual shutdowns. The 1980s saw numerous brief closures under President Reagan, though most lasted only a few days.

The nature of shutdowns changed dramatically in the 1990s when they became weapons in broader political battles over spending priorities and policy objectives.

The Evolution of Political Shutdowns

1976-1990: Early Era – Brief and Frequent

During this period, shutdowns occurred frequently but lasted just hours or a few days. These were often technical lapses rather than deliberate political standoffs. President Reagan presided over eight shutdowns, the longest being just three days. One shutdown in 1982 occurred simply because members of Congress were attending social events rather than voting on spending bills.

1995-Present: Modern Era – Longer and More Contentious

The Clinton-Gingrich shutdowns of 1995-1996 marked a turning point, with closures lasting weeks rather than days. Since then, shutdowns have become increasingly tied to major policy debates, from the Affordable Care Act in 2013 to border wall funding in 2018-2019. These extended closures have had more visible economic impacts but, surprisingly, minimal lasting market effects.

The Four Major Government Shutdowns That Actually Impacted Markets

While there have been 11 funding gaps since 1980, only four lasted long enough to broadly disrupt government operations and potentially move markets. Let’s examine each in detail, including where the S&P 500 stood relative to its highs and how it performed in the aftermath.

November 14-19, 1995: Clinton-Gingrich Shutdown #1

Duration: 5 days

Cause: President Bill Clinton vetoed Republican spending bills that included cuts to Medicare, education, and environmental programs. Speaker Newt Gingrich and congressional Republicans sought to reduce government spending growth, while Clinton prioritized protecting social programs.

Impact: Approximately 800,000 federal workers were furloughed.

Resolution: Congress passed a temporary funding bill after five days to allow continued negotiations.

S&P 500 Performance:

• Distance from 52-week high when shutdown started: Near all-time highs (S&P 500 had crossed 500 for the first time in March 1995)
• During 5-day shutdown: +1.3%
• One week after start: +1.5%
• One month after start: +2.8%
• 100 days after shutdown ended: +8.1%
• One year after shutdown ended: Strong gains (market continued uptrend weith +23.1% from end to end of 1996)

December 16, 1995 – January 6, 1996: Clinton-Gingrich Shutdown #2

Duration: 21 days

Cause: The November shutdown’s temporary funding expired. Republicans demanded that Clinton use Congressional Budget Office projections showing the budget could be balanced in seven years with specific cuts. Clinton refused, insisting on using Office of Management and Budget projections that required fewer cuts to social programs.

Impact: About 284,000 federal workers furloughed. Cost $400 million in back pay to furloughed employees. Public opinion turned decisively against Republicans. Polls showed 46% blamed the GOP vs. 27% blaming Clinton.

Resolution: Senate Majority Leader Bob Dole, running for president in 1996, pushed to end the standoff. On New Year’s Eve, Dole declared on the Senate floor that Republicans should end the shutdown. Clinton’s approval ratings surged after the shutdown ended.

S&P 500 Performance:

• Distance from 52-week high when shutdown started: Down 3.7% from recent highs
• During 21-day shutdown: +0.8%
• One week after start: Essentially flat (-0.2%)T
• One month after start: +1.2%
• 100 days after shutdown ended: +6.2%
• One year after shutdown ended: +23.1%

October 1-17, 2013: The Obamacare Shutdown

Duration: 16 days

Cause: Congressional Republicans, led by Senator Ted Cruz and encouraged by conservative groups like Heritage Action, refused to pass spending bills that funded the Affordable Care Act (Obamacare). Cruz delivered a famous 21-hour speech on the Senate floor protesting the healthcare law. President Obama and Democratic lawmakers repeatedly rejected Republican proposals to delay or defund Obamacare.

Impact: Furloughed 800,000 employees and delayed payment to 1.3 million workers. Shaved 0.1-0.2% off GDP growth. Cost the economy an estimated $24 billion. Congressional approval ratings fell to a record-low 9%.

Resolution: Bipartisan Senate negotiations produced a deal with only minor changes to Obamacare. The government reopened on October 17, 2013.

S&P 500 Performance:

• Distance from 52-week high when shutdown started: Within 5% of 52-week highs
• During 16-day shutdown: +3.1%
• One week after start: +2.0%
• One month after start: +4.5%
• 100 days after shutdown ended: +10.2%
• One year after shutdown ended: +19.72%

December 22, 2018 – January 25, 2019: The Border Wall Shutdown (Longest in U.S. History)

Duration: 35 days

Cause: President Donald Trump demanded $5.7 billion in funding for a wall along the U.S.-Mexico border. Senate Democrats, led by Minority Leader Chuck Schumer, refused to support this funding. After Democrats took control of the House on January 3, 2019, newly elected Speaker Nancy Pelosi also opposed the wall funding. Neither party could break the impasse.

Impact: Affected approximately 800,000 federal workers – 380,000 furloughed, while 420,000 worked without known payment dates. Delayed $140 billion in IRS tax refunds. Disrupted FBI investigations. Caused airports to close due to TSA staffing problems. The Congressional Budget Office estimated the shutdown cost $3 billion in permanent economic losses and shaved 0.4% off quarterly GDP growth.

Resolution: After 35 days, mounting pressure, particularly following widespread travel delays caused by air traffic controllers calling out sick, led Trump to agree to a three-week temporary spending deal on January 25, 2019. The deal reopened the government without funding for the border wall.

S&P 500 Performance:

• Distance from 52-week high when shutdown started: Down 17.5%
• During 35-day shutdown: +10.3%
• One week after start: +2.5%
• One month after start: +9.3%
• 100 days after shutdown ended: +18%
• One year after shutdown ended: +26.2%

S&P 500 Performance During Government Shutdowns: What the Data Really Says

Looking beyond individual shutdowns and focusing on the bigger picture reveals a clear trend. Since the current budget process began in 1976, the U.S. has seen 21 full government shutdowns (plus one ongoing as of October 2025). On average, these have lasted about 8 days.

And despite the headlines, history shows that shutdowns don’t derail the stock market. In fact, the S&P 500 has often posted modest gains during shutdowns and even stronger rebounds afterward.

One month after the shutdown starts has a standout stat: since 1980, the S&P 500 has been higher one month after the start of every single shutdown. That’s a 100% success rate.

So even if the market dips at first, investors typically regain confidence fast. Once it’s clear the shutdown is temporary, the market tends to bounce back quickly.

Twelve Months After Shutdown Ends?

• Average return: +16.95% since 1980
• Positive returns: 86% of the time
• Median return: +18.9% (for shutdowns lasting 10+ days)
  • After 2018-2019 shutdown: +36%
  • After 1995-1996 shutdown: +26%
  • After 2013 shutdown: +19.72%

Shutdowns grab headlines, but they’ve rarely shaken long-term investor confidence. In most cases, they’ve been seen as political noise more than economic threats.

Since 1990, the S&P 500 has actually gone up during every shutdown. And over time, bigger factors, like economic growth, corporate earnings, and interest rates, have mattered far more to market direction than temporary budget standoffs.

Looking at the data, it’s clear that government shutdowns haven’t hurt long-term investors. If anything, they’ve often created buying opportunities for those who stay calm and think long term.

Why Markets Remain Resilient

Economic Impact: Limited and Temporary

Government shutdowns reduce quarterly GDP growth by an estimated 0.1-0.2% per week. However, this impact is almost entirely reversed once the government reopens because furloughed workers receive back pay and delayed spending catches up. The net long-term economic effect approaches zero.

Forward-Looking: Markets Price Future Conditions

Investors focus on corporate earnings, economic growth prospects, and monetary policy, not temporary political dysfunction. Markets assume government shutdowns will eventually end and look through the short-term noise to the underlying fundamentals.

Predictable Resolution: Shutdowns Always End

Unlike debt ceiling crises that could trigger actual default, shutdowns have clear endpoints. Public pressure eventually forces politicians to compromise. Investors understand this dynamic and don’t panic over what they know is a temporary situation.

Modern Context: Shutdowns Are Expected

With six shutdowns since 1990, investors have experience with these events. Shutdowns no longer surprise markets the way they might have decades ago. This familiarity reduces panic selling and irrational behavior.

The Current 2025 Government Shutdown

As of November 4, 2025, the federal government has been shut down for 35 days, matching the record set during the 2018-2019 closure. This shutdown began on October 1, 2025, when Congress failed to pass funding legislation for fiscal year 2026.

Current Shutdown Details: October 1, 2025 – Present

Cause: Senate Democrats and Republicans blocked separate continuing resolutions from the House. Democrats opposed Republican bills lacking extensions of Affordable Care Act subsidies that were temporarily expanded under the American Rescue Plan Act of 2021. Republicans voted against Democratic bills that included these subsidy extensions.

Scope: This is a full government shutdown because none of the 12 appropriations bills for 2026 were passed. Approximately 900,000 workers have been furloughed, with another 2 million working without pay. By October 20, the Supplemental Nutrition Assistance Program (SNAP) faced critical funding shortages.

Unique Factor: President Trump has indicated the potential permanent elimination of some federal positions if the shutdown continues, diverging from past government shutdowns, where all workers eventually returned.

What’s Driving Market Strength?

Current Status: The S&P 500 continues trading near all-time highs despite the shutdown entering its sixth week, demonstrating that markets prioritize corporate fundamentals and monetary policy over Washington dysfunction.

Artificial Intelligence: AI Investment Boom

Major technology companies have announced massive, multi-year commitments to AI infrastructure. Meta and Microsoft’s large-scale chip and data center investments have lifted the entire AI ecosystem, driving market gains that overshadow shutdown concerns.

Federal Reserve: Rate Cut Expectations

Markets are pricing in a 70% chance of rate cuts in December. Without shutdown-delayed economic data, the Fed is expected to deliver “risk management” cuts to offset potential economic weakness.

Corporate Earnings: Strong Q3 Fundamentals

The S&P 500 is reporting blended earnings growth of approximately 8.5-9% year-over-year for Q3 2025, marking the ninth consecutive quarter of earnings growth. Over 83% of companies beat earnings expectations, above both 5-year and 10-year averages. 

Historical Precedent: Investors Know the Playbook

With multiple government shutdowns in recent years, investors understand these are temporary political events. The market’s positive performance during the 2018-2019 record shutdown provides a roadmap for current investor behavior.

What Investors Should Do (and Not Do) During Government Shutdowns

Historical evidence and current market behavior provide clear guidance for investors navigating government shutdowns. The worst mistake is making emotional decisions based on political headlines rather than economic fundamentals.

Stay the Course

The most important lesson from shutdown history is simple: do nothing. Markets have consistently rewarded patient investors who maintained their positions through political uncertainty. The best response to a shutdown is usually no reaction at all.

• Don’t panic sell based on shutdown headlines
• Maintain your long-term investment plan and asset allocation
• Remember that government shutdowns are temporary political events, not economic crises
• Focus on your investment horizon, not daily news cycles

Consider Buying Opportunities

If government shutdowns create market weakness, particularly in the lead-up to or early days of closure, history suggests these present buying opportunities rather than reasons to sell. Markets often decline by 10% or more before extended shutdowns, then recover strongly afterward.

• Pre-shutdown market declines have historically been reversed
• S&P 500 has been higher one month after every shutdown start since 1980
• Twelve-month returns averaging nearly 17% after government shutdowns end
• Broad market exposure through index funds captures post-shutdown recovery

What to Monitor During Government Shutdowns

Economic Data: Watch for Delayed Reports

Government shutdowns disrupt economic data releases from agencies like the Bureau of Labor Statistics. Markets may experience higher volatility when key reports are delayed, as seen with suspended jobs data during the current shutdown. This creates information gaps but doesn’t change the underlying economic conditions.

Corporate Earnings: Focus on Fundamentals

Company earnings reports continue during government shutdowns and matter far more for stock prices than political dysfunction. Strong earnings results can easily overwhelm shutdown concerns, as seen in the current shutdown, where tech earnings have driven market highs.

Federal Reserve: Monetary Policy Matters Most

Interest rate decisions and Fed commentary often have greater market impact than government shutdowns themselves. The 2018-2019 shutdown coincided with a Fed pivot to dovish policy, which drove the market recovery more than the shutdown resolution.

Shutdown Duration: Length Doesn’t Predict Returns

Surprisingly, there’s no clear relationship between shutdown duration and market performance. The longest shutdown (35 days) produced the best returns. Don’t assume extended government shutdowns necessarily mean worse market outcomes.

Final Thoughts

Government shutdowns always sound scary. They dominate headlines, stir up political drama, and create real stress for federal workers and families. But when you look at how the market responds, the story changes completely.

Since 1980, the S&P 500 has gone up one month after every single government shutdown. That’s not just a trend, that’s a 100% success rate.

Markets don’t fixate on temporary gridlock in Washington. They care about earnings, growth, and interest rates. Political noise might grab attention, but it rarely moves the needle long-term. The data from past shutdowns proves it: even during some of the longest and most heated standoffs, the S&P 500 kept climbing.

The current 2025 shutdown is no different. Despite being one of the longest in U.S. history, the market’s still hovering near record highs. Why? Because investors are focused on AI growth, strong earnings, and expected Fed rate cuts.

So, what should you take away from all this? Simple: don’t let the headlines throw you off your game. History shows that staying invested through political drama has paid off time and time again. And if anything, shutdowns often create windows of opportunity—not reasons to panic.

In the end, the numbers don’t lie: shutdowns shake Washington, not Wall Street.
