A potential U.S. government shutdown is looming in a matter of days and weighing on risk appetite in financial markets on Tuesday. Yet history shows that they’re relatively common, resolved quickly, and don’t tend to keep the S&P 500 index from advancing.
That’s according to Brian Levitt, the New York-based global market strategist for Invesco, which managed almost $1.54 trillion as of June 30. His remarks come as the U.S. federal government is headed toward a partial shutdown Sunday morning, if lawmakers don’t act fast enough.
The U.S. has experienced a total of 21 government shutdowns in its history, he said, citing the Treasury Department. On average, they’ve been resolved within eight days; five of them lasted only a day and the longest stretched on for 34 days. And during shutdowns, the S&P 500

has posted positive returns during 12 of the 21 shutdowns, and eked out a 0.1% average return, Levitt said in emailed comments distributed on Monday.
This time around, however, there’s a lot of simultaneous risks that investors are grappling with — from rising interest rates to the possible revival of inflation amid expanded labor strikes, in addition to the resumption of student-loan payments that could sap spending. U.S. stocks

remain on track for a losing September as of Tuesday, with long-term Treasury yields near their highest levels in a dozen years or more.

“While unnerving, concerns about shutdowns shouldn’t change investors’ long-term investment plans,” Levitt wrote in his comments, which were also posted online earlier this month. “This isn’t the first government shutdown, and it’s likely not the last.”
U.S. stocks opened lower on Tuesday amid ongoing worries about a shutdown, which Moody’s Investors Service said would be “credit negative” for the U.S. As of afternoon trading, Dow industrials were down by more than 250 points or 0.8%. Meanwhile, the S&P 500 and Nasdaq Composite were respectively off by 1.1% and 1.2%.

On average, the S&P 500 has advanced in the aftermath of government shutdowns, by roughly 7% in the 100 days that follow, Levitt told MarketWatch on Tuesday. Volatility increased some — but not all — of the time, based on moves derived from returns on Dow industrials, he said.
