Dow Slides Nearly 1,000 Points as Oil Surge Rekindles Market Fears

The Dow Jones Industrial Average dropped nearly 1,000 points, or about 2%, while the S&P 500 declined 1.2% and the Nasdaq Composite slipped roughly 1%. Industrial and cyclical companies led the downturn, including Boeing and Caterpillar, which tend to be particularly sensitive to global economic slowdowns.

The Dow Jones Industrial Average dropped nearly 1,000 points, or about 2%, while the S&P 500 declined 1.2% and the Nasdaq Composite slipped roughly 1%. Industrial and cyclical companies led the downturn, including Boeing and Caterpillar, which tend to be particularly sensitive to global economic slowdowns.

The sell-off came as oil prices surged following reports that Iran struck an oil tanker with a missile, intensifying fears of supply disruptions in the Middle East. U.S. West Texas Intermediate crude jumped roughly 6% to trade above $79 per barrel, briefly touching $79.97, while Brent crude, the international benchmark, rose above $84.

The spike in energy prices is raising alarm because of the region’s strategic importance to global supply chains.

The Strait of Hormuz, a critical shipping corridor responsible for roughly 20% of the world’s oil supply, remains a focal point of the conflict. Investors are increasingly worried that disruptions there could ripple through global markets, increasing inflation and slowing economic growth.

Geopolitical uncertainty is also fueling broader concerns about U.S. involvement in the conflict. Analysts noted that investors are questioning whether the United States can safely guarantee shipping routes through the region without escalating the situation further.

Donald Trump recently said the U.S. is preparing to escort commercial vessels through the Persian Gulf, though officials have not provided a timeline for when conditions might stabilize.

Adding to the tension, Pete Hegseth said additional military forces are moving into the region while asserting that the U.S. is “winning decisively.”

At the same time, economic policy remains in flux, with the administration signaling that a newly announced 15% global tariff could take effect as soon as this week.

Despite the broader market decline, Berkshire Hathaway was a rare bright spot during the session. Shares rose after the conglomerate disclosed it had resumed share buybacks for the first time since 2024, while CEO Greg Abel personally purchased $15 million worth of stock.

The broader market reaction reflects how quickly geopolitical events can shift investor sentiment. With oil markets now tightly linked to the evolving situation in the Middle East, traders are bracing for continued volatility across both energy and equity markets.
