Wall Street Wrap: S&P 500, Nasdaq and Dow Daily — 2026-09-10

Top developments

Oil Breaches $100, Dragging Indices Lower

On Wednesday, September 9, the S&P 500 fell 0.6%, the Nasdaq Composite declined 0.5%, and the Dow Jones Industrial Average dropped 0.8%, extending a losing streak that began earlier in the week. The primary driver was crude oil, with Brent crude hitting $100 per barrel due to escalating tensions in the Gulf region. This energy shock directly impacted equity valuations by raising inflation expectations and increasing input costs for consumer discretionary and industrial sectors.

Treasury Yields Hit Multi-Year Highs

The 10-year US Treasury yield surged to its highest level since 2023, pressuring growth stocks and rate-sensitive sectors. The move reflects a repricing of Fed policy; after a stronger-than-expected jobs report in early September, market participants have increased bets that the Federal Reserve may raise interest rates at its next meeting rather than hold steady. This shift in rate expectations has weighed heavily on the tech-heavy Nasdaq, which is particularly sensitive to higher borrowing costs.

Holiday-Shortened Week Opens with Volatility

The week began with significant volatility following the Labor Day holiday. On Tuesday, September 8, the Dow dropped approximately 600 points as oil prices began their sharp ascent toward $100. The initial sell-off was driven by "inflation jitters" returning to the forefront of investor concerns, overriding previous optimism about a soft landing. The continued pressure through Wednesday suggests that the market is struggling to find a bottom amidst conflicting macro signals of strong labor data and rising commodity costs.

Local view

Japanese financial media highlighted the ripple effect of US market moves on Asian equities. Fisco reported that the US stock market's continued decline on September 9, driven by high oil prices and renewed inflation concerns, led to selling pressure in Japan. The report noted that the yen strengthened against the dollar, which negatively impacted Japanese exporters like Toyota, while also referencing analyst warnings from RBC that the S&P 500 could face a short-term decline of up to 10% due to these macro factors.
