Crude oil climbed above $97 per barrel after reports of new military activity involving Iran and the United States, reigniting concerns about global energy supplies.

Oil Prices Rise as Middle East Tensions Escalate
Global financial markets faced renewed uncertainty after oil prices surged on reports of increased military activity involving Iran and the United States.
Brent crude, the international benchmark for oil prices, rose 1.1% to $97.07 per barrel, reversing recent declines and moving closer to the psychologically important $100 level.
The increase followed reports that Iran launched missiles toward Kuwait and Bahrain, although the missiles reportedly failed to reach their intended targets. In response, the United States said it carried out strikes against an Iranian military ground control facility located on an island in the Strait of Hormuz.
The developments raised concerns that escalating tensions could disrupt energy supplies in one of the world’s most strategically important oil-exporting regions.
Energy markets remain highly sensitive to events in the Middle East, particularly those involving the Strait of Hormuz, through which a significant portion of global oil shipments pass.
Wall Street Retreats From Record Levels
The rise in oil prices created headwinds for U.S. equity markets, causing major indexes to pull back from recent highs.
The S&P 500 declined 0.3%, moving slightly away from its record level. The Dow Jones Industrial Average lost 339 points, equivalent to a 0.7% decline, while the technology-heavy Nasdaq Composite fell 0.3%.
Although the declines were relatively modest, they reflected investor caution as higher energy costs and geopolitical risks added uncertainty to the market outlook.
Rising oil prices can increase inflationary pressures by raising transportation, manufacturing, and consumer costs. Investors often worry that sustained increases in energy prices could slow economic growth and complicate monetary policy decisions.
As a result, sectors sensitive to borrowing costs and consumer spending came under pressure during the session.

Treasury Yields Move Higher
The bond market also reacted to the rise in oil prices.
The yield on the benchmark 10-year U.S. Treasury note increased to 4.48%, up from 4.46% a day earlier. Before the recent conflict began, the same yield was trading closer to 3.97%.
Higher Treasury yields generally increase borrowing costs across the economy, affecting everything from mortgages and business loans to corporate financing.
The increase in yields placed additional pressure on equities, particularly smaller companies that often rely more heavily on borrowing to finance expansion and operations.
Reflecting these concerns, the Russell 2000 index, which tracks smaller U.S. companies, fell 0.9%, underperforming the broader market.
Mixed Corporate Earnings Drive Individual Stocks

Despite broader market weakness, several individual stocks posted significant gains following earnings announcements and corporate updates.
GameStop emerged as one of the strongest performers of the day. The video game retailer’s shares jumped 7.7% after reporting a 14% increase in quarterly revenue compared to the previous year.
Investor enthusiasm was further boosted by the company’s announcement of a share repurchase programme worth up to $2 billion. Stock buybacks often appeal to investors because they reduce the number of shares outstanding and can enhance shareholder value.
Medical technology company Medtronic also delivered positive results, rising 5.3% after reporting stronger-than-expected earnings and announcing an increase in its dividend payout.
Not all earnings-related news was well received. Department store chain Macy’s initially traded higher after reporting profits that exceeded analyst forecasts but later reversed course to finish down 0.9%.
Similarly, cybersecurity company Palo Alto Networks declined 6% despite surpassing earnings expectations. Investors may have been expecting even stronger results given the stock’s impressive 61.3% gain earlier in the year.
Artificial Intelligence Continues to Drive Market Optimism
One of the strongest themes supporting global equity markets remains the rapid growth of artificial intelligence.
AI-related companies continued to attract investor attention, with Marvell Technology extending its recent rally. The stock gained another 7.1% after surging 32.5% in the previous session, marking its best trading day on record.
The latest gains followed comments from Nvidia CEO Jensen Huang, who suggested during a conference in Taiwan that Marvell could become “the next trillion-dollar company.”
The remarks reinforced investor enthusiasm surrounding AI infrastructure, semiconductors, and data center technologies, sectors that continue to benefit from growing demand for advanced computing capabilities.
The AI boom has become one of the most powerful drivers of stock market performance globally, helping offset concerns related to interest rates, inflation, and geopolitical risks.
Global Markets Deliver Mixed Performance
Outside the United States, stock market performance was mixed.
European indexes generally moved lower as investors reacted to the same geopolitical developments affecting U.S. markets.
In Asia, performance varied significantly across markets. Hong Kong’s Hang Seng Index declined 1.6%, reflecting weakness in regional sentiment.
In contrast, Japan’s Nikkei 225 climbed 2.5% to another record high. A major contributor to the rally was computer chip equipment manufacturer Tokyo Electron, whose shares surged 13.4%.
The gains highlight how investor enthusiasm for semiconductor and AI-related businesses continues to support markets despite broader geopolitical uncertainty.
Outlook
Financial markets remain caught between two powerful forces: rising geopolitical risks and continued optimism surrounding artificial intelligence and corporate earnings growth. While higher oil prices and Treasury yields are creating short-term pressure on equities, investor appetite for technology and AI-related companies remains strong. As long as tensions in the Middle East persist, energy markets are likely to remain volatile, making oil prices and Treasury yields key indicators for investors in the weeks ahead.
