U.S.-Iran Airstrikes Spark Oil Surge, Threaten Strait of Hormuz Stability

Escalating Hostilities in the Strait of Hormuz

Tensions in the Middle East intensified over the weekend as the U.S. and Iran traded military strikes, drawing immediate focus to the Strait of Hormuz. Tehran declared the vital commercial waterway closed following a weekend of strikes on U.S. facilities in multiple Gulf countries. The conflict began after an attack by Iran on a commercial ship transiting the strait, which led President Donald Trump to order airstrikes against Iran on Saturday. However, President Trump disputed Tehran’s claim of a closure on Sunday, saying the key waterway was open to commercial traffic. U.S. officials reported that approximately 20 vessels had been escorted through the strait in the 24 hours leading up to the announcement.

The military exchange prompted a surge in oil prices as markets weighed the potential for global energy supply disruptions. Brent crude futures rose 3.7% to $78.86 per barrel, while West Texas Intermediate advanced more than 3% to $74.05. Reuters reported that Brent crude climbed 3.3% in early trade to reach $78.50 a barrel, up from a recent trough of $70.14, while U.S. crude added 3.4% to $73.83 a barrel. Despite the initial jump, markets appear to be “downplaying” recent developments in the Middle East, according to Allan Small, senior investment adviser at iA Private Wealth.

Market Reaction and Earnings Expectations

Stock futures signaled a cautious start to the week, with Dow Jones Industrial Average futures slipping 135 points, or 0.3%, on Sunday night. S&P 500 futures lost 0.3%, while Nasdaq-100 futures were down 0.5%. Investors are shifting their attention to a heavy calendar of corporate earnings and economic reports. Major firms are set to headline the first big earnings week, including Goldman Sachs, JPMorgan Chase, GE Aerospace, Morgan Stanley, UnitedHealth, J.B. Hunt Transport Services, United Airlines, and American Airlines. Additionally, Taiwan Semiconductor is set to report June sales on Monday and second-quarter results on Thursday, while ASML is also scheduled to kick off chip earnings.

“We seem to be in a holding pattern until we start to get some of these corporate earnings coming out. The war (with Iran) can make the markets do crazy things, but we seem to be in this holding pattern for now,” said Allan Small, senior investment adviser at iA Private Wealth. Ben Emons, founder of Fed Watch Advisors, noted: “The Strait closure will hang over the market with a risk-off tone.”

Inflation Data and Federal Reserve Policy

Beyond the Gulf conflict, investors are monitoring upcoming inflation figures and the Federal Reserve’s policy trajectory. The June Consumer Price Index (CPI) report is set for release on Tuesday, which some analysts suggest could show cooling in the headline rate of 4.2% as petrol prices decline, though that trend may reverse due to rising oil prices. A Producer Price Index (PPI) inflation report is scheduled for Wednesday. Fed Chair Kevin Warsh is due to face Congress for the first time in his new role this week, with testimony scheduled for both Tuesday and Wednesday. The dollar gained with bond yields as investors nudged up the chance of a hike in interest rates from the Federal Reserve.

Global Outlook and Sector Performance

In Asia, markets opened higher on Monday as investors initially shrugged off the tensions. Japan’s Nikkei 225 added 0.28%, while the Topix advanced 0.72%. South Korea’s Kospi was up 0.58%, and the small-cap Kosdaq jumped 1.84%. Australia’s benchmark S&P/ASX 200 remained flat at the open. However, subsequent reports indicated the Nikkei lost 1% as fighting in the Gulf intensified. In North America, the S&P/TSX composite index recently finished up 104.86 points at 35,305.31, while the Dow Jones industrial average rose 149.60 points to 52,637.01. The S&P 500 index closed up 31.75 points at 7,575.39, and the Nasdaq composite gained 74.72 points to 26,281.61.

Individual stocks are also under observation. Cisco Systems, Robinhood Markets, Sandisk, Micron Technology, and Nvidia are currently situated around buy areas. Conversely, Space Exploration Technologies, known as SpaceX, hit a new low. President Trump stated on social media that he had agreed to continue talks with Iran but warned that the United States had told the country, “in no uncertain terms, that the Cease Fire is OVER!”
