Markets opened the week on edge as fresh military strikes between the United States and Iran reverberated through energy and equity markets.
U.S. stock futures moved lower early Monday as investors digested the geopolitical developments and prepared for a heavy slate of second-quarter corporate earnings. By 04:53 ET (08:53 GMT), S&P 500 futures had fallen 0.3%, Nasdaq 100 futures were down 1% and Dow Jones futures were up 0.03%. Technology names appeared particularly vulnerable after pronounced losses among Asian semiconductor stocks.
Geopolitics and earnings shape the week
For the coming days, two central themes are set to influence market direction: the trajectory of military tensions in the Middle East and the flow of quarterly earnings. Higher crude prices risk reviving inflation concerns, while company results should help clarify whether investments in artificial intelligence continue to support stronger revenue and profit trajectories.
Investors are watching these forces closely because higher energy costs can feed into broader inflation measures, and quarterly reports will provide fresh data on the extent to which corporate spending on AI infrastructure is translating into earnings growth.
Clash over the Strait of Hormuz
Markets remained alert after the United States and Iran exchanged strikes over the weekend, producing conflicting statements about the condition of the Strait of Hormuz - a vital corridor for global oil shipments.
U.S. Central Command reported it had carried out a new round of strikes against dozens of targets across Iran intended to reduce Tehran’s capability to threaten shipping through the strait. Iran announced it was closing the Strait of Hormuz, a claim that U.S. officials disputed, saying commercial shipping continued.
President Donald Trump rejected Iranian assertions that the waterway had been closed and said it remained open to commercial traffic. The opposing accounts have left market participants uncertain about global energy supply prospects, particularly given that roughly one-fifth of the world’s seaborne oil typically transits the Strait of Hormuz.
Because of that throughput, the waterway has emerged as the principal geopolitical risk to monitor. Any sustained interruption there could further elevate crude prices, intensify inflationary pressure and add costs for consumers and businesses.
Oil spikes as traders price risk
Energy markets reacted sharply in European trading, with Brent crude rising 4.8% to $79.65 a barrel and U.S. West Texas Intermediate crude increasing 5% to $74.98. Both benchmarks had already climbed more than 4% in the prior week as tensions escalated.
The recent gains followed Iran’s announcement that it was closing the Strait of Hormuz, a statement U.S. officials disputed, asserting that commercial shipping was ongoing. The episode heightened volatility as market participants sought to gauge whether oil flows from the region would be materially disrupted.
Higher crude typically translates into elevated gasoline prices and greater transportation costs, which can flow through to broader inflation. While energy companies may benefit from rising prices, industries such as airlines, transport and consumer discretionary firms could face additional margin pressure if crude continues to climb.
Semiconductor selloff despite durable AI demand
Asian chip stocks tumbled, led by a near 14% collapse in SK Hynix shares in South Korea. That drop was the main driver of a more than 5% slide in South Korea’s KOSPI index and prompted the Korea Exchange to briefly halt trading.
The decline in memory-chip shares appeared driven by profit-taking and investor caution ahead of an intense earnings period rather than a clear weakening in demand for AI-related chips. The timing came after SK Hynix’s successful Nasdaq debut the prior week.
By contrast, Taiwan Semiconductor Manufacturing Co. reported another robust quarter, with second-quarter revenue up 36% from a year earlier to T$1.27 trillion, underscoring continued strong demand for chips used in artificial intelligence infrastructure.
The divergence highlights that short-term market sentiment can push semiconductor stocks sharply lower even as underlying demand for AI hardware remains intact. Upcoming corporate results will be important in determining whether the sector’s elevated valuations are justified by fundamentals.
Earnings season in focus
Beyond the geopolitical backdrop, investors are turning their attention to a packed week of second-quarter earnings that could help set market direction. After months of robust gains, much of which has been attributed to enthusiasm around artificial intelligence, companies face the task of proving that earnings growth can match high investor expectations.
Technology firms are under particular scrutiny following the recent selloff in the sector. Market participants will be looking for confirmation that spending on AI infrastructure continues to drive stronger revenues and margins. Results will also feed into the broader debate about inflation and the path for U.S. interest rates.
Historically, earnings can matter more than headlines. Strong quarterly reports can quickly restore investor confidence after pullbacks, while disappointing guidance has the potential to trigger sharp declines in individual stocks and broader market indices.
What to watch this week
- Developments in U.S.-Iran military actions and any further statements about the status of the Strait of Hormuz.
- Oil price moves and their pass-through effects on transportation and consumer sectors.
- Second-quarter corporate results, especially from technology and semiconductor companies, for signs that AI spending is translating into durable revenue and profit growth.
Market participants will be weighing both geopolitical risk and company-level earnings to determine whether the recent rally can continue, or whether renewed volatility will press equities lower.
