The S&P 500 (^GSPC) closed at 6,861.89, down 19.42 points, or 0.28%, for the session. The Dow Jones Industrial Average (^DJI) closed at 49,395.16, falling 267.50 points, or 0.54%, at 5:45:36 PM EST.

Stocks pulled back, snapping a three-day winning streak, as escalating tensions between the United States and Iran sent oil prices to six-month highs and shifted investor sentiment from “Greed” to “Caution.”
The Nasdaq Composite also finished lower, as geopolitical risk overshadowed recent gains fueled by artificial intelligence enthusiasm and solid corporate earnings.
The key catalyst behind Thursday’s market reversal was a sharp rise in crude prices following comments from President Donald Trump, who issued a 10–15-day ultimatum to Tehran regarding nuclear negotiations. The defined timeline has intensified what traders describe as a “war premium” in energy markets, creating a time-boxed window of heightened volatility.
Global benchmark Brent Crude climbed above $71 per barrel, marking its highest level in six months. U.S. benchmark West Texas Intermediate also surged, reflecting growing concerns that diplomatic failure could disrupt oil flows in the Middle East.
At the center of investor anxiety is the Strait of Hormuz, a narrow waterway that handles roughly 20% of global oil shipments. Any threat to tanker traffic through the passage could significantly tighten global supply and push prices higher. Reports indicate that U.S. naval deployments in the region are at their largest scale since 2003, further amplifying market sensitivity to headlines.
The rise in oil prices has also revived concerns about inflation, potentially complicating the policy path for the Federal Reserve. The nomination of Fed governor Kevin Warsh and his potential influence on future central bank leadership has added another layer of uncertainty.
Safe-haven demand increased alongside oil’s rally. Gold hovered near $5,000 per ounce, remaining close to record territory as investors sought protection against geopolitical risk and possible inflation shocks.
Corporate developments took a back seat to macro concerns. Shares of Walmart rebounded earlier in the session after the retail giant reported better-than-expected revenue. However, broader market weakness limited the stock’s impact on major indices. Walmart’s total revenue increased by 5.6% in Q4 FY26, while operating income rose 10.8%.
Elsewhere, alternative asset manager Blue Owl Capital drew scrutiny after reports that it had restricted withdrawals in certain private credit funds, highlighting liquidity risks in less-transparent segments of financial markets. The move contributed to a cautious tone among institutional investors already wary of geopolitical escalation.
Market strategists say the most critical development is not simply that stocks declined, but the clearly defined 10–15-day diplomatic deadline. The “Trump Iran Deadline” has become the primary volatility driver, with traders recalibrating risk exposure ahead of potential developments.
While recent gains were driven by AI momentum and strong earnings, energy-driven inflation fears and geopolitical uncertainty are now dominating market narratives. With oil at six-month highs and diplomatic tensions unresolved, investors are bracing for continued volatility across equities, commodities, and safe-haven assets in the days ahead.
