Markets brace for US government shutdown – what’s the impact on stocks?
Once more a shutdown of the US government is a possibility. But how does the S&P 500 fare in such a scenario, and should investors worry?
US government shutdown looms
It looks like some parts of the U.S. government might stop operating on 1 October unless a last-minute agreement is reached. But remember, this is not the same as a debt default, which could be much worse. Historically, these government shutdowns usually don't last very long, averaging about 8 days in length.
This situation looks a lot like the 2013 shutdown, which was mainly about funding for Obamacare. This time, the main issues are border security and funding for Ukraine. The 2019 shutdown, which was longer, only involved a quarter of the government being closed.
What happens during a shutdown?
During a shutdown, interest on U.S. Treasury bonds (T-Bonds) won't be affected, and Social Security payments will keep coming. However, people working in national security and other necessary jobs will have to work without pay, while other government employees might be temporarily laid off without pay. Some economic data collection might stop during a shutdown, which could affect reports on employment, inflation, and gross domestic product (GDP). How long the shutdown lasts will determine if these reports are delayed or skipped.
Will it cause a recession?
Even though some politicians suggest a shutdown could cause an economic downturn, history doesn't support this. The only two times GDP decreased during a shutdown, the U.S. was already in a recession. Each week of a government shutdown is estimated to reduce GDP growth by 0.1%, but this is usually made up once government workers get their back pay.
What’s the market impact?
Previous government shutdowns haven't really affected the stock market much. The S&P 500 (an index that represents the stock market) has had about an equal number of gains and losses during these shutdowns. The longest shutdown, which was in 2019, actually saw a strong increase in the stock market.
Historically, the S&P 500 tends to see gains during a government shutdown. Of the 21 shutdowns since 1976, he average gains during the shutdown itself is 0.3%. The following year witnesses a gain of 12% on average.
Shutdown a navigable risk
While a government shutdown on 1 October seems likely, it probably won't have a big impact on the financial markets. Shutdowns are usually short and mostly affect the timing of economic activity, not causing a big risk of a recession. The overall stock market probably won't be heavily affected, although companies that rely a lot on government spending might see some negative effects.
