Wall Street Closed: What Variables Will Emerge When It Reopens Tomorrow?

On the 7th (local time), U.S. markets were closed for Labor Day. However, heading into this week, the S&P 500 fell 0.4%, the Dow slipped 0.5%, and the Nasdaq dipped 0.3% on the previous trading day, the 4th.

The August employment report significantly beat expectations, raising concerns by reviving the possibility of a Federal Reserve rate hike in September. In the market, the odds of a 25 bp increase at the next meeting are now viewed at roughly over fifty percent, bringing the “additional tightening” scenario back to life. Fed Chair Powell’s hawkish remarks at Jackson Hole further support this outlook.

As the Fed enters a communication blackout ahead of the September FOMC, upcoming inflation data—producer prices on the 10th and consumer prices on the 11th—are seen as key events that could determine the future path of rates and market direction.

On the corporate front, there were virtually no notable earnings releases due to the holiday closure, and investors are maintaining a wait-and-see stance ahead of major tech earnings scheduled later in the week and key technology and telecom conferences.

In global markets, a semiconductor rally and rising commodities both stood out. Asia’s markets rose, with Japan’s Nikkei up 2.1% and South Korea’s KOSPI up 4.6%, led by large-cap tech stocks boosted by expectations of strong AI-driven memory chip demand.

Meanwhile, mutual attacks between U.S. and Iranian tankers and warships have heightened risks in the Strait of Hormuz, pushing Brent crude to a six-week high, trading in the upper $90s per barrel. U.S. retail gasoline prices also hit a record Labor Day high of $4.14 per gallon, raising concerns about future inflation and a slowdown in consumer spending.

Even during the holiday, S&P 500 and Nasdaq futures traded slightly lower, reflecting a cautious stance. As the New York cash market reopens tomorrow, the combination of strong employment, a hawkish Fed, high oil prices and Iran risk, alongside still-robust AI and semiconductor investment expectations, is likely to increase volatility. In particular, Korean investors should closely watch the combined effects of interest rates, oil prices, and semiconductor market trends on U.S. flows, the Korean won, and the KOSPI.
