US Stock Market Crashed: Why Dow Jones Fell 630 Pts? Nasdaq, S&P 500 Down; Wall Street September 9th Outlook

The US stock market crashed heavily overnight after a 3-day-long weekend due to rising crude oil prices and an intensified geopolitical crisis in the Middle East. The US has eliminated five Iranian tankers near Kharg Island in response to attempted missile attacks by Iran on their warships. Amidst the Iran conflict, the inflationary risks fear have taken a toll on sentiment, with investors awaiting the upcoming US inflation data scheduled later this week. On Wednesday, US stock futures have steadied in the early hours.

Dow Jones + Nasdaq + S&P 500

The Dow Jones crashed 628.18 points or 1.2% to end at 52,786.07 overnight, taking the worst hit in comparison to its peers. Among major draggers were Amgen, which crashed over 10%, followed by Salesforce which dropped 4%. Stocks like Home Depot and Sherwin-Williams tanked 2.3% each, while Johnsons & Johnsons, Nvidia and Visa Ince declined around 2% each.

Heavyweights like JP Morgan, Merck, IBM, Apple Inc, Microsoft, Walmart, Travelers Cos, Nike and Boeing plunged by 1% to 1.5% as well. These stocks majorly impacted Dow Jones.

Explaining the market sentiment, a report of Charles Schwab said, major indexes mostly fell early thanks to the usual suspects: rising Treasury yields and crude oil. Attacks on Saudi Arabia's oil facilities earlier today, tit-for-tat strikes between Iran and the U.S., growing trade tensions with Canada, and rising prospects of central bank hikes combined forces in a stiff headwind, though 10-year note yields eased from early highs above 4.8%.

The Nasdaq Composite closed at 29,507.70, down by 36.45 points or 0.12%. While the S&P 500 index slipped 45.08 points or 0.58% to finish at 7,673.52.

Mostly credit-sensitive stocks toppled Wall Street. Palantir and Amazon were also down 2.3% and 0.6% ahead of their sterling bond offering.

The Dow Jones futures traded at 52,797, down by 35 points in the early hours of Wednesday. On the contrary, the Nasdaq 100 futures gained marginally by 58.50 points to trade at 29,597.25, while the S&P 500 futures edged higher by 6.25 points to trade at 7,686.75.

US stock futures stabilized on Wednesday after the major averages declined in the previous session, pressured by rising oil prices that heightened concerns over inflation and the potential for higher interest rates. The moves came after the US struck five Iranian tankers near Kharg Island in retaliation for attempted missile attacks on a US warship. Investors are also awaiting key US inflation data this week, which could provide further insight into the Federal Reserve's rate path ahead of its meeting next week. Markets are currently pricing in roughly a 60% probability of a 25-basis-point rate hike, as per Trading Economics.

As per Schwab's note, investors spent the long weekend digesting surprisingly vigorous August U.S. jobs data and now stare down inflation readings due later this week. Corporate news isthin with earnings season over, keeping central bank activity and geopolitics front and center eight weeks before U.S. elections.

"July's job losses were revised away, and we've now seen six straight months of payroll gains," said Collin Martin, head of fixed income research and strategy at the Schwab Center for Financial Research (SCFR). "With all eyes on the potential 'hold versus hike' discussion at the next FOMC meeting, in a vacuum this could lend support for the 'hike' camp, but inflation matters more right now."

US Stock Market Outlook On September 9, 2026

Though inflation data looms, the rate implications of the jobs report can't be ignored, as per Schwab.

"This just raises the risk of a hike this year," Martin said.

"We should know this week how much above $4 billion the operations are, as Secretary Bessent suggests it's the floor, and operations could be larger," Martin said. "Higher yields are not something that necessarily need to be fixed. The economy is growing and the fed funds rate is near neutral (or below), so a positively sloped yield curve makes sense."

Furthermore, Schwab's note stated that with jobs data behind, this week's Producer Price Index (PPI) on Thursday and Consumer Price Index (CPI) on Friday represent the final key data points heading into next week's Fed meeting. Early CPI consensus is 0.4% monthly for headline and 0.2% for core, which excludes food and energy.

"I'm not sure how resilient U.S. equities will be if the Iran conflict gets worse and oil prices and yields continue to march higher," said Nathan Peterson, director of derivatives research and strategy at SCFR. "Throw in bearish seasonality during the month of September, along with the potential for higher volume and adjustments to positioning when most fund managers and traders come back from vacation Tuesday, and I'm going to stay with a cautious outlook."
