Government Shutdowns: What Investors Should Know
What Is a Government Shutdown and Why Does It Happen?
A government shutdown occurs when Congress fails to pass legislation funding federal agencies and programs. Most government operations rely on annual appropriations bills, which Congress must approve and the president must sign before the new fiscal year begins on Oct. 1.
If Congress fails to enact those bills, or a temporary funding measure called a continuing resolution, many federal agencies must suspend non-essential activities until funding resumes. Essential services, such as national security, air traffic control, and certain health and safety functions, continue to operate, as do programs funded through mandatory spending like Social Security and Medicare.
How Common Are Shutdowns and What is Their Economic Impact?
Shutdowns are not rare in U.S. history. Since the 1970s, there have been more than 20 shutdowns, most lasting only a few days. The longest episodes include:
- Feb. 14, 2026, to April 30, 2026: 76 days (President Trump)
- Sept. 30, 2025, to Nov. 12, 2025: 43 days (President Trump)
- Dec. 22, 2018, to Jan. 25, 2019: 34 days (President Trump)
- Dec. 16, 1995, to Jan. 6, 1996: 21 days (President Clinton)
- Oct. 1-17, 2013: 16 days (President Obama)
Although disruptive, shutdowns have historically had limited economic impact. The Congressional Budget Office estimated that the 2018-2019 shutdown permanently reduced GDP by about $3 billion, even though the economy eventually recovered most of the lost output.
The 76-day shutdown that ended April 30, 2026, the longest in U.S. history, carried a considerably larger economic footprint, with extended delays in federal services and data releases compounding its effect. Longer shutdowns can also delay the release of key economic data, including insights about the U.S. labor market, inflation, and consumer spending, which can complicate Federal Reserve policy decisions and affect markets.
How Do Markets Respond and What Does It Mean for Investors?
Financial markets have at times treated shutdowns as short-term political events rather than fundamental economic shocks, although market reactions have varied depending on broader economic conditions. Historically, some brief shutdowns have shown little effect on corporate earnings or long-term equity performance, though this has not been consistent across all periods or market environments. During the 2013 and 2018 shutdowns, for example, the S&P 500 experienced positive performance in the 100 days following the end of each shutdown. The 2018 shutdown coincided with a broader market correction unrelated to the funding lapse, and stocks rallied while the government remained closed.
Even for shutdowns lasting more than 10 days, some historical data suggest limited long-term impact on equity markets, but outcomes have varied across time periods and economic environments. The S&P 500’s median performance during past extended shutdowns remained relatively stable. Market outcomes typically depend more on fundamentals, such as corporate earnings and overall economic strength, than on political gridlock.
Bond markets have at times remained relatively stable during shutdowns because the Treasury continues to make interest payments and conduct auctions. However, heightened economic and policy uncertainty can change that dynamic. While history shows yields often decline during shutdown periods, concerns about political risk and fiscal conditions can put upward pressure on Treasury yields.
Recent Context and Guidance
The frequency and length of the two most recent shutdowns represent a departure from historical norms, where most shutdowns lasted only a few days. The economic and market impacts, while manageable, were more pronounced than in shorter historical episodes. Delays in key economic data releases, including employment and inflation reports, complicated Federal Reserve decision-making and added uncertainty to markets during both shutdowns.
Despite these disruptions, equity markets in certain periods demonstrated resilience, consistent with the historical pattern of limited long-term impact on market performance. Bond markets saw some yield volatility, particularly amid broader concerns about fiscal sustainability and political uncertainty.
As always, we monitor fiscal and legislative developments and their potential implications for investors. But more important than short-term developments may be maintaining a long-term perspective and a diversified investment approach, which is designed to navigate periods of policy uncertainty.
