Market Summary: Dow Opens Lower on Oil, Yield Pressures

Key Market Moves:

US markets opened sharply lower on September 15, 2026, with the Dow Jones falling 253 points, the S&P 500 down 0.23%, and the Nasdaq declining 0.30%. The selloff was driven by rising oil prices, elevated Treasury yields, and uncertainty surrounding artificial intelligence demand.

Energy Markets:

Oil prices continued climbing amid Middle East tensions. Brent crude rose 0.6% to $106.31 per barrel, while WTI increased 1.2% to $102.59, following Saudi Arabia's shutdown of a key pipeline bypassing the Strait of Hormuz. Rising energy costs intensified inflation concerns.

Treasury Yields:

The 10-year US Treasury yield hit 5.041%—its highest level since 2007—before settling near 4.996%. Elevated yields reduce equities' relative appeal and pressure valuations, particularly for growth stocks.

Technology Sector:

AI concerns weighed on tech stocks following calls from AI executives to slow advanced model development. Alphabet and Microsoft each fell approximately 1%. Notably, Nvidia bucked the trend with gains of 1.12%, while other chipmakers traded in a narrower range. Uncertainty remains about how slower AI development might impact corporate spending on computing infrastructure.

Other Notable Movers:

Dave & Buster's Entertainment plummeted over 7% after reporting second-quarter revenue below expectations. Waystar also saw movement, though specific details were limited.

Federal Reserve Outlook:

Markets are pricing in a 92% probability of a quarter-point rate increase at Wednesday's Fed decision, raising rates from the current 3.5%-3.75% range. Recent inflation data showed consumer prices accelerating in August, with underlying inflation posting its largest increase in four months.

Barclays strategists warned that sustained yields above 5% could become a persistent headwind for equities despite continued earnings momentum.
