Global stock markets rallied sharply Monday while oil prices declined after the United States and Iran reached a tentative agreement to extend their ceasefire and reopen the Strait of Hormuz, raising hopes that the conflict that has fueled inflation and disrupted global energy markets may finally be moving toward a lasting resolution.
Investors responded positively to the news, driving gains across major stock indexes in the United States, Europe, and Asia. Lower oil prices also boosted confidence that inflationary pressures could begin easing, reducing the need for additional interest rate hikes from central banks worldwide.
Markets Celebrate Signs of Stability
Wall Street posted strong gains as investors welcomed the prospect of a more stable Middle East and improved global energy supplies.
The S&P 500 climbed 1.9%, while the Dow Jones Industrial Average gained 719 points, or 1.4%. The Nasdaq Composite led the rally with a 3% increase as technology and artificial intelligence stocks surged.
A major catalyst for the market’s optimism was a sharp drop in oil prices. Brent crude fell 5.4% to $82.61 per barrel, a significant decline from the more than $100 per barrel seen just weeks ago. Although prices remain above pre-war levels, the decline offered hope that businesses and consumers may soon experience relief from higher costs linked to energy, transportation, and food production.
Strait of Hormuz Agreement Offers Hope
Iran confirmed the tentative agreement but indicated that implementation would not begin until the deal is formally signed. Pakistan, which helped mediate discussions, said the signing is expected to take place Friday in Switzerland.
The agreement is expected to reopen the Strait of Hormuz, one of the world’s most important energy shipping routes. However, broader negotiations concerning Iran’s nuclear program and other issues are expected to continue for another 60 days.
Despite the positive developments, analysts caution that significant challenges remain. Any delays or disagreements could still derail the agreement, and experts note that it may take months for global energy supply chains to fully recover even after the strait reopens.
Airlines and AI Stocks Lead Wall Street Gains
Companies that are heavily affected by fuel prices were among the market’s biggest winners.
United Airlines jumped 5.2%, while American Airlines rose 3.7%. Cruise operator Carnival gained 4.1% as investors anticipated lower operating costs if oil prices continue to decline.
Artificial intelligence-related stocks also posted impressive gains. The sector has experienced heightened volatility in recent weeks amid concerns that enthusiasm surrounding AI investments may have pushed valuations too high.
Micron Technology surged 9.9%, Advanced Micro Devices climbed 7.2%, and Nvidia gained 3.5%. As the most valuable company in the market, Nvidia provided one of the strongest boosts to the overall performance of the S&P 500.
Meanwhile, Elon Musk’s SpaceX advanced 9.8% during its second day of trading on Wall Street. Investor enthusiasm helped push the company’s valuation above $2.1 trillion, making it larger than Exxon Mobil, Bank of America, and Coca-Cola combined.
Interest Rate Expectations Shift
Bond markets also reflected growing optimism.
The yield on the benchmark 10-year U.S. Treasury note eased to 4.46% from 4.48% late Friday, signaling increased confidence that inflation pressures may begin to moderate.
Last week, Europe’s central bank became the first major central bank to raise interest rates in response to elevated inflation. Investors have been closely watching whether the U.S. Federal Reserve might follow a similar path.
The Federal Reserve is scheduled to announce its latest interest rate decision later this week, marking the first meeting under new Chair Kevin Warsh. President Donald Trump has repeatedly urged the central bank to lower rates.
While traders still expect the Fed to keep rates unchanged this week, expectations for a future rate hike have declined significantly. According to CME Group data, traders now see only a 56% chance of a rate increase later this year, down from 71% just one week ago.
Global Markets Join the Rally
The optimism spread far beyond Wall Street.
Japan’s Nikkei 225 jumped 5% to a record high, making it one of the strongest-performing major indexes worldwide.
“This is great news,” said Takashi Hiroki, chief strategist at Monex. “Buying by foreign investors is leading the market with expectations of easing tensions around the situation in the Middle East.”
South Korea’s Kospi surged 5.2%, supported by continued strength in technology and AI-related companies such as Samsung Electronics.
European markets also advanced broadly, although London’s FTSE 100 bucked the trend and slipped 0.4%.
Corporate Deals Create Mixed Reactions
Not all market news was positive.
Roku fell 0.9% after announcing that Fox Corp. would acquire the streaming company in a cash-and-stock deal valued at approximately $22 billion.
The decline came despite Roku shares already having surged 20% on Friday following reports that a deal was imminent. The acquisition will provide Fox with access to Roku’s streaming platform, first-party consumer data, and more than 100 million streaming households worldwide.
Fox shares, however, dropped 16.1% as investors assessed the costs and risks associated with the major acquisition.
Financial markets worldwide welcomed the tentative U.S.-Iran agreement as a potential turning point for global stability, energy prices, and inflation. While important hurdles remain before the deal is finalized and fully implemented, investors are betting that easing tensions in the Middle East could reduce economic uncertainty and support growth across global markets. The coming weeks, including the formal signing of the agreement and upcoming Federal Reserve decisions, will be critical in determining whether this rally has lasting momentum.
