Government Shutdowns Impact on Markets
Washington is back in the headlines as the federal government faces a shutdown if policymakers can’t reach a new funding agreement. Political drama in Washington can create uncertainty. While the toll that shutdowns have on government workers can be real, their effect on financial markets has historically been minimal. In the past 50 years, the average one-month return of the S&P 500 following a government shutdown is approximately +1.2% with shutdowns lasting an average of 9 days.
Government shutdowns have occurred regularly since 1980 under presidents of both parties, with minimal long-term impact on financial markets. The chart illustrates that this was true even during the most contentious shutdowns, including during the Reagan administration, Clinton’s 21-day shutdown in 1995, Obama’s 16-day shutdown in 2013, and Trump’s 35-day shutdown in late 2018 to early 2019. For investors, shutdowns have generally served as temporary disruptions rather than fundamental threats to economic growth.
On an annual basis, the federal government must pass a budget for the next fiscal year, which begins on October 1. While the government passed the “One Big Beautiful Bill Act” earlier this year that lays out tax and spending policies, a budget is needed to allocate the actual dollars to different departments and agencies. Failure to do so by the deadline means that the government might face a shutdown, resulting in a lapse in government services and employees being furloughed.
It’s rare for Congress to pass budget bills on time. This may not be surprising given the increasingly polarized political environment in Washington, where compromise has become more difficult to achieve. Over nearly fifty years, Congress has managed to pass appropriations bills before the fiscal year deadline only a few times, making last-minute negotiations the norm rather than the exception. One solution that Congress has used often is known as a “continuing resolution” which temporarily funds the government while lawmakers negotiate. Republicans are currently proposing a seven-week stopgap bill for this purpose.
The current situation reflects disagreements over spending priorities, primarily around healthcare. While the immediate funding of the government is the focus, these budget battles reflect deeper differences around the role of government and fiscal responsibility. With federal debt now around 120% of GDP, many agree on the need for fiscal discipline but there is fundamental disagreement as to how this should occur.
The threat of a government shutdown may blend in with other fiscal issues such as the debt ceiling. The debt ceiling becomes a problem when spending the government has already approved needs to be paid for, but the Treasury Department isn’t authorized to borrow above a certain limit. The only solution in these cases is for Congress to raise the debt limit, or else the government risks defaulting on its obligations. All of these fiscal challenges are one reason the major credit rating agencies have downgraded the U.S. debt below AAA. Fortunately, the One Big Beautiful Bill Act also raised the debt ceiling by $5 trillion, so this problem can be avoided for some time.
Tariffs and taxes earlier this year created significant challenges for investors. However, with recent clarity around both issues, uncertainty has diminished. While a shutdown could always result in “wall of worry,” history shows that even longer government disruptions have not generally impacted investors.
