On Tuesday, the stock market took a slight tumble as threats of a U.S. government shutdown loomed large. In a rather surprising twist, September seemed set for a stronger-than-usual finish on Wall Street.

To give you an idea, the S&P 500 slipped by 0.2%, the Nasdaq Composite lost about 0.4%, and the Dow Jones Industrial Average fell by 159 points, or 0.3%.

In the realm of politics, House Speaker Mike Johnson, a Republican from Louisiana, expressed his scepticism about avoiding a shutdown by the midnight deadline. He mentioned to CNBC that the matter was in the hands of Senate Minority Leader Chuck Schumer and House Minority Leader Hakeem Jeffries. Jeffries, on the other hand, remarked that if a shutdown occurs, it lies at the feet of the Republicans.

A government shutdown isn’t typically a mover of markets. However, given the current climate of investor caution over a slowing labour market, the dangers of stagflation, and heightened stock valuations, this time could be different. Moreover, rating agencies might reconsider U.S. credit strength, especially after a downgrade from Moody’s in May.

Should the government halt operations, the Labour Department would not issue the September nonfarm payrolls report. This report, usually scheduled for Friday, is key to understanding the U.S. economy’s trajectory ahead of the Federal Reserve’s upcoming policy meeting. Meanwhile, consumer confidence, alas, fell below expectations on Tuesday.

Jack Janasiewicz, portfolio strategist and manager at Natixis Investment Managers, noted that any delay in economic data collection, due to a shutdown, could heighten uncertainty. This uncertainty often translates to increased market volatility.

“Could such uncertainty notably affect the economic landscape and risk assets?” he pondered. “Probably not in a lasting way, yet if protracted, the risk augments,” he added.

Government shutdowns are rarely lengthy, often lasting no more than a fortnight. While Wall Street anticipates a stop of two weeks or fewer, there remains unease about potential economic impacts, especially if controversial actions, such as mass firings of federal workers, were to unfold.

Adam Crisafulli of Vital Knowledge chimed in, observing that while a shutdown seemed expected, a duration beyond a fortnight might start to unsettle the market.

On a more industry-specific note, software stocks saw declines on Tuesday. Paychex fell by 4% after reporting quarterly results, and Salesforce dipped by 2%. However, Nvidia shone brightly, buoyed by news from CoreWeave. CoreWeave, backed by Nvidia, secured a significant $14.2 billion AI cloud deal with Meta Platforms.

Even with Tuesday’s retreat, the major U.S. stock indexes are headed for a decent monthly performance as September draws to a close. Historically, September has seen an average drop of 4.2% for the S&P 500 over five years, yet this month shows a 2% increase. The Dow logged a 1% gain, with the Nasdaq shining at a 5% increase.

As the third quarter wraps up, noteworthy figures arise: the S&P 500 is up 7%, the tech-laden Nasdaq prepares for a 10% quarterly gain, and the blue-chip Dow boasts a 4% rise since June’s end, marking its fifth consecutive quarterly advance.
