Oil prices took a sharp tumble on Tuesday, providing relief to jittery bond markets and giving a modest lift to equities. The S&P 500 closed up 0.3%, edging closer to its record high from earlier this month, while the Dow Jones Industrial Average gained 160 points (0.3%) and the Nasdaq composite climbed 0.7%.
The most notable action was in crude markets, where Brent crude fell 3.6% to $87.27 a barrel—its second consecutive decline after 13 gains in 14 sessions. The drop came despite escalating US-Iran tensions, with the Trump administration announcing new sanctions aimed at further crippling Iran's economy. Brent had swung between $72 and $102 last month as traders weighed the possibility of a US-Iran deal that would allow tankers to exit the Persian Gulf freely.
Diplomatic efforts continued meanwhile, with a Pakistani delegation leaving Iran after talks with President Masoud Pezeshkian on reopening the Strait of Hormuz and restarting negotiations to end the Iran-US conflict. Pakistan's Interior Minister Mohsin Naqvi described the meeting as "very positive and productive."
The retreat in oil prices eased concerns about inflation, which had pushed Treasury yields higher throughout the summer. Last week, the Treasury Department announced a surprise increase in its repurchases of longer-dated notes and bonds—a move that some analysts, including billionaire investor Stanley Druckenmiller, have criticized as market tampering. The yield on the 10-year Treasury fell to 4.63% from 4.70% late Monday and 4.74% at the end of last week. While that's a significant move, the 10-year yield remains well above its 3.97% level before the Iran conflict sent oil prices and inflation fears soaring.
High yields raise borrowing costs across the economy, potentially slowing growth and pressuring asset prices. The bond market's recent turbulence has also fueled political debate, with former President Trump pushing for Federal Reserve rate cuts even as he downplayed the bond market alarm.
On Wall Street, AI-related stocks led the rebound. Nvidia rose 2.2%, recovering from a 2.9% drop the previous day that had weighed heavily on the S&P 500. AI shares have been volatile all summer on concerns that valuations have run ahead of actual profits. Nvidia's quarterly results, due Wednesday, could set the tone for the sector.
Elsewhere, Dick's Sporting Goods plunged 30.7%—its worst drop on record—after the retailer missed earnings expectations and cut its 2026 profit forecast. Executive Chairman Ed Stack said the company slashed prices on footwear and apparel to stay competitive, while some new shoe launches underperformed. The company also lowered guidance for its recently acquired Foot Locker business.
Consumer confidence weakened more than expected in August, according to the Conference Board, adding to worries about household spending—the main engine of the US economy. With prices still elevated and the job market showing signs of softness, the resilience of consumer demand is in question.
Global markets were mostly steady, with South Korea's Kospi—led by AI heavyweights—rising 0.7%, one of the largest gains worldwide. The index has been stabilizing after a 22.2% plunge in July. The oil price decline also provided some relief for energy-importing nations, though diesel prices remain above $7 in several US states, reflecting lingering supply concerns.
