Stocks Fall as Iran War Fears & Oil Prices Rise – March 4, 2026

Market Volatility Returns as Iran Conflict Escalates

Stocks resumed their downward trajectory Thursday, reversing a brief respite from the previous day, as renewed concerns over the widening conflict in the Middle East sent oil prices climbing. The Dow Jones Industrial Average experienced a significant drop, falling 974 points, or 2%, while the S&P 500 declined 1.2% and the Nasdaq Composite dipped 1%. The sell-off was particularly pronounced among companies sensitive to global economic slowdowns, including Boeing and Caterpillar.

The renewed market anxiety stems from escalating tensions with Iran. Iran stated Thursday it hit an oil tanker with a missile, prompting a surge in crude oil prices. U.S. West Texas Intermediate crude futures jumped 6% to trade above $79 per barrel, briefly reaching $79.97, its highest level since June 2025. International benchmark Brent crude followed suit, rising over 3% to more than $84 per barrel. This price increase reverses a period of stabilization seen on Wednesday, which had briefly boosted the Dow by over 200 points.

Oil Prices and Inflationary Pressures

The spike in oil prices is a key driver of market concern, raising fears of renewed inflationary pressures. A sustained increase in energy costs could complicate the Federal Reserve’s plans for potential interest rate cuts. The price of oil is particularly sensitive given recent geopolitical events. As of March 3, 2026, WTI crude was trading around $76 per barrel, a significant increase from its level of approximately $70 a week prior, as reported by WBUR.

Iran’s Stance and U.S. Response

Adding to the uncertainty, Iranian Foreign Minister Abbas Araghchi indicated Thursday that Iran is not seeking a ceasefire with the U.S. And Israel, signaling a continued escalation of the conflict. This statement contrasts with earlier efforts to de-escalate tensions and raises questions about the potential duration and scope of the conflict.

The U.S. Government has attempted to reassure markets, with President Donald Trump suggesting the U.S. Is prepared to provide risk insurance and escorts to ships navigating the Strait of Hormuz, a critical waterway for global oil supplies. However, a firm timeline for ensuring the safety of oil tankers through the strait remains unclear. Approximately a third of the world’s seaborne crude exports pass through the Strait of Hormuz, and a prolonged disruption could push Brent crude prices above $100 per barrel, according to analysis cited in FXStreet.

Defense and Energy Sectors See Mixed Reactions

While the broader market experienced declines, certain sectors saw varied reactions. Defense contractors, such as Lockheed Martin, RTX Corporation, and Northrop Grumman, continued to benefit from the increased geopolitical tensions, posting solid gains. Palantir Technologies also saw an upgrade to a “buy” rating from Rosenblatt, with its price target raised to $200, citing the company’s capabilities in defense and artificial intelligence.

Energy companies, however, presented a more complex picture. While crude oil prices rose, Exxon Mobil, ConocoPhillips, and Chevron extended multi-day gains, suggesting investor confidence in their ability to capitalize on higher energy prices.

Broader Economic Concerns and Investor Sentiment

The escalating conflict has prompted investors to question whether the U.S. Has underestimated the challenges of the situation. Sam Stovall, chief investment strategist at CFRA Research, questioned the feasibility of the U.S. Ensuring safe passage for vessels through the Strait of Hormuz, raising concerns about potential liabilities and the impact on U.S. Debt levels. This sentiment reflects a growing unease about the potential economic consequences of a prolonged conflict.

Berkshire Hathaway a Standout Performer

Amidst the widespread market decline, Berkshire Hathaway emerged as a bright spot, gaining over 1% after announcing the resumption of share repurchases for the first time since 2024. CEO Greg Abel also personally purchased $15 million worth of Berkshire Hathaway stock, signaling confidence in the company’s future prospects. This move provided a counterpoint to the overall negative market trend. More details on Berkshire Hathaway’s share repurchase program can be found here.

Treasury Yields and the Fed’s Dilemma

The oil-driven inflation scare has also impacted U.S. Treasury yields, with the 10-year yield climbing toward 4.10% after briefly dipping below 4%. This increase in yields reflects growing concerns about inflation and the potential for the Federal Reserve to delay or abandon plans for interest rate cuts. The interplay between geopolitical events, energy prices, and monetary policy is creating a complex and uncertain environment for investors.

What’s Next: Monitoring Geopolitical Developments and Economic Data

Looking ahead, market participants will be closely monitoring developments in the Middle East, particularly any further escalation of the conflict and its impact on oil supplies. The next key data point will be the upcoming inflation reports, which will provide further insight into the potential for sustained inflationary pressures. Investors will also be paying attention to any statements from the Federal Reserve regarding its monetary policy outlook. The situation remains fluid, and market volatility is likely to persist as long as geopolitical tensions remain elevated. The U.S. Treasury Department also announced this week that President Trump’s recently announced 15% global tariff will likely go into effect this week, adding another layer of economic uncertainty, as reported by CNBC.
