U.S. Government Shutdown Scare Is Over, But Not the Stock Market's Headwinds

TradingKey - The longest U.S. government shutdown in history has concluded after President Donald Trump signed a temporary spending bill, removing a key macroeconomic hurdle. While the resumption of federal operations clears some obstacles, investors should temper optimism for a sustained bull market, as concerns over the AI bubble and the Federal Reserve's rate cut outlook signal increasing volatility ahead.

This 43-day government shutdown, which led to a substantial number of federal employees being furloughed and adversely affected sectors including aviation, healthcare, and food services, finally ended after extensive political negotiations between the two major U.S. parties on core issues like Medicaid.

Historically, Markets are Well-Positioned

For capital markets, the end of the government shutdown signifies the resumption of federal spending. The U.S. Treasury's General Account, which had been absorbing approximately $700 billion from the market without outflows, can now normalize liquidity injections, alleviating fears of a "liquidity crunch" over the past half-month.

Against the backdrop of a resolved political drama and the prospect of revitalized economic activity, both the S&P 500 and Dow Jones Industrial Average have posted four consecutive days of gains, while the tech-heavy Nasdaq Composite has remained relatively flat.

Historically, U.S. government shutdowns have not had a significant impact on stock market trends. The S&P 500 actually rose over 2% in October during this period, even hitting an all-time high.

Compared to the "debt ceiling crisis" earlier this year, which could have triggered a U.S. debt default, the "U.S. government shutdown crisis" primarily involves the disruption of public services, and thus does not pose severe systemic financial risks.

Encouragingly, the end of government shutdowns typically aids market strength, thanks to the resumption of economic data releases providing clearer macroeconomic insights and a renewed appetite for risk.

Carson Group notes that the stock market often sees significant gains after the federal government reopens, with an average increase of 12.7% over the subsequent 12 months.

Ultimately, the liquidity squeeze characterized by a surge in overnight funding market SOFR rates in late October may have just been a "false alarm."

Bumpy Road Ahead for U.S. Equities

However, the path for U.S. equities to continue their ascent, and for the S&P 500 to achieve its first consecutive three years of over 20% gains since the 1990s, is not smooth. As of November 12, the S&P 500 is up 16.48% year-to-date in 2025; if it can climb to 7,000 points, it would record a 19% annual gain.

Some analysts contend that the market has been "flying blind in a data vacuum." Despite the end of the U.S. government shutdown, the market still requires a strong catalyst to break through to new highs. Adverse shifts in the monetary policy outlook, trade risks, and the AI earnings narrative could all trigger a corrective pullback in U.S. stocks.

The increasingly stark divisions within the Federal Reserve remain an unavoidable topic when considering monetary policy adjustments this year. After Fed Chair Jerome Powell stated that "a December rate cut is not a foregone conclusion" following the October meeting, hawkish voices within the Fed have grown louder.

Raphael Bostic, President of the Federal Reserve Bank of Atlanta, stated on Wednesday that inflation remains the greater risk to the U.S. economy, and the current state of the job market does not warrant an aggressive Fed response while inflation remains too high.

Bostic favors holding interest rates steady in December, warning that further easing could re-energize inflation and unsettle inflation expectations among businesses and consumers.

Boston Fed President Susan Collins also emphasized that while a weakening job market warrants attention, downside risks to employment do not appear to have increased further since the summer, and the risk of inflation remaining above the 2% target requires careful consideration. In this highly uncertain environment, she supports maintaining current interest rate levels for some time.

Earlier this month, remarks from Wall Street executives at Goldman Sachs and Morgan Stanley reignited "AI valuation concerns," while the Q3 earnings reports from AI cloud infrastructure companies CoreWeave and Nebius further confirmed operational pressures in the AI business. SoftBank Group's liquidation of $5.8 billion worth of Nvidia shares also made prominent headlines.

Wells Fargo, which recently downgraded S&P IT sector ratings covering popular stocks like Nvidia, expressed concern that tech stock valuations have climbed sharply. Excessive optimism and elevated expectations could leave technology stocks vulnerable to a near-term pullback driven by disappointment.
