Oil Prices Jump as US and Iran Exchange Strikes in Hormuz Strait

Oil Prices Surge Amid Strait of Hormuz Standoff

Oil prices climbed significantly on Monday following a weekend of renewed military strikes between the United States and Iran in the Middle East. The international standard, Brent crude, rose 9.6% to $83.30 per barrel. The price surge follows a series of missile and drone assaults in the Gulf, as both the United States and Iran asserted control over the Strait of Hormuz. The escalation has disrupted the transit of crude oil, with shipping data from Kpler showing that only six vessels passed through the strait on Sunday, the lowest volume in five weeks. President Donald Trump announced the reinstatement of a blockade to prevent tankers carrying Iranian oil from using the waterway. Additionally, the U.S. has called for a 20% payment on all cargo shipments passing through the strait to reimburse the United States for providing security in the region. While the price of Brent crude remains below its wartime peak of nearly $120 per barrel, the volatility has unsettled global markets.

AI-Linked Stocks Face Significant Losses

Global stock markets reacted negatively to the geopolitical tension and a cooling of the artificial-intelligence boom. On Wall Street, the Nasdaq composite fell 1.6%, while the S&P 500 dropped 0.8% and the Dow Jones Industrial Average fell 138 points. Chip stocks, which previously experienced significant growth due to the AI rush, faced heavy selling pressure. Micron Technology fell 4.4%, and Nvidia, the largest stock on Wall Street by value, dropped 3.5%. The sell-off was particularly intense in Asia; South Korea’s Kospi index plunged 8.9%, driven by a 15.4% drop in SK Hynix stock. This decline marked the worst single-day performance for SK Hynix since it began trading in 1997. Investors are expressing growing concern that stock valuations may have become overstretched and that the demand for AI-related computing building blocks may not remain sustainable if productivity and profit expectations are not met.

Market Outlook and Earnings Season

Wall Street’s focus is shifting toward the upcoming quarterly profit reports. The sustainability of the current market rally remains a central question for investors. The following table summarizes the market reaction to the week’s opening volatility:

Geopolitical Stakes and Economic Policy

The renewed violence in the Persian Gulf has cast doubt on the future of an interim U.S.-Iranian agreement signed last month, which intended to reopen the strait following a 60-day negotiation period. The duration of the current slowdown in shipping remains a critical factor for the global economy.

Economists warn that if the disruption of oil shipments continues from days to weeks, it could rekindle inflationary pressures that appeared to have peaked in May. Such an outcome could force the Federal Reserve and other central banks to resume interest rate hikes. While higher interest rates are intended to curb inflation, they also carry the risk of slowing economic activity and negatively impacting interest-rate-sensitive sectors, such as homebuilders. Investors are now looking toward upcoming June Consumer Price Index (CPI) and Producer Price Index (PPI) data for further clarity on the trajectory of the economy.
