- Washington contested Iran’s claim, asserting the strategic waterway remains operational under American naval protection

Global crude markets experienced a significant rally Monday following an escalation in hostilities between Washington and Tehran, sparking renewed concerns over supply security through the world’s most critical oil transit route.
Brent crude futures advanced 3.5% to reach $78.68 per barrel. The U.S. benchmark West Texas Intermediate similarly gained 3.5% to settle at $73.89 per barrel. Earlier trading sessions saw both benchmarks spike as high as 4.5% before moderating.
The price surge followed weekend attacks by Iranian forces deploying missiles and unmanned aerial vehicles against Gulf nations, including Qatar and the United Arab Emirates. These strikes represented Tehran’s retaliation for American military operations targeting Iranian installations.
Iran’s Revolutionary Guards subsequently announced an indefinite closure of the Strait of Hormuz. This declaration followed an incident where a commercial tanker was struck and ignited, compelling the crew to evacuate the burning vessel.
Strategic Implications of Hormuz Disruption for Energy Markets
The Strait of Hormuz represents the planet’s most critical petroleum shipping corridor. Roughly one-fifth of global oil consumption passes through this narrow waterway, including exports from major producers Saudi Arabia, Iraq, Kuwait and the United Arab Emirates.
Prolonged interruptions would compel Asian petroleum refineries to secure alternative supply sources while simultaneously driving up maritime transportation and insurance expenses.
Maritime tracking systems recorded merely six vessel passages through the strait Sunday, representing the weakest traffic volume in five weeks.
U.S. Central Command asserted via social media platform X that the waterway remained “open to all vessels seeking to lawfully transit,” directly challenging Tehran’s closure announcement.
Nevertheless, shipping companies exercised extreme caution. Maritime traffic experienced a dramatic slowdown throughout the weekend, according to research from ANZ analysts.
Equity Markets Suffer Broad Declines
Asian equity indices experienced substantial losses Monday. South Korea’s Kospi benchmark plunged as much as 9% during intraday trading, pressured by intense selling in technology equities.
SK Hynix plummeted more than 15% in Seoul trading. The memory chip manufacturer has shed nearly 40% of its market capitalization since reaching an all-time peak last month. This decline followed gains of almost 13% in its U.S.-traded shares after completing a historic $26.5 billion capital raise on Wall Street.
Samsung Electronics declined over 10%. Japanese semiconductor equipment manufacturers Advantest and Tokyo Electron also posted significant losses.
Market participants are simultaneously focused on the approaching corporate earnings period. Financial results from TSMC and ASML are scheduled for release this week, alongside quarterly reports from major Wall Street institutions JP Morgan, Bank of America and Goldman Sachs.
Market strategist Fawad Razaqzada warned the situation possesses potential for rapid deterioration, although energy analysts emphasized crude is unlikely to revisit the extreme valuations witnessed when the conflict initially erupted in February.
The International Energy Agency reported last week that prolonged disruptions to Hormuz maritime traffic could undermine anticipated improvements in worldwide petroleum supply. Global production had recovered by 4.1 million barrels daily in June as transit through the strait temporarily normalized.
