The ongoing war between the United States and Iran has led to the effective closure of the Strait of Hormuz, a critical chokepoint for global energy supplies, resulting in the largest oil supply disruption in history [4]. President Donald Trump has issued a firm ultimatum, demanding that Iran reopen the Strait by Tuesday at 8 p.m. ET, threatening to decimate every bridge and power plant in Iran within four hours if his deadline is not met [3][4]. Trump stated, "We have to have a deal that's acceptable to me, and part of that deal is going to be — we want free traffic of oil and everything else" [4]. He also noted that Iran's leadership is negotiating in good faith, but described their latest proposal as "not good enough" while acknowledging it as a significant step [3][4].
The closure of the Strait has resulted in a surge in crude, jet fuel, diesel, and gasoline prices since the war began [4]. On Monday, West Texas Intermediate crude futures rose 0.7% to $113.25 per barrel, while Brent crude gained about 0.68% to settle at $109.77 per barrel [3][4]. Nearly 1 billion barrels are projected to be lost by the end of the month, including up to 600 million barrels of crude oil and roughly 350 million barrels of refined products, according to TD Securities [4]. Rapidan Energy estimates a total net loss of 630 million barrels of oil and products by the end of June, even after accounting for redirected flows, emergency stockpile releases, and inventory drawdowns [4].
The market reaction has been significant. Asian stock markets initially lost direction following Trump's remarks, but later climbed as traders assessed the developments, with Australia's S&P/ASX 200 up 1.4%, Japan's Nikkei 225 rising 0.35%, and South Korea's Kospi advancing 1.5% [2][3]. However, the energy crisis has forced several Asian countries to implement emergency measures. Indonesia announced remote work policies to reduce oil consumption, Vietnam urged citizens to limit private vehicle use, and Myanmar is facing deepening economic uncertainty due to energy shortages [2]. Many Asian airlines have introduced hefty fuel surcharges, and transportation constraints are raising fears of conditions reminiscent of the COVID-19 pandemic [2].
OPEC+ members agreed to increase production by 206,000 barrels per day in May, but it remains unclear how this oil will reach the market with the Strait still closed [4]. Kuwait Petroleum Corporation reported significant damage to several operational facilities from drone attacks, further complicating the supply situation [4]. The conflict is expected to last at least into deep April, with analysts warning that the "barrel math becomes increasingly grim" as the crisis continues [4].
Forward-looking statements from analysts highlight the uncertainty and severity of the situation. Ryan McKay, senior commodity strategist at TD Securities, emphasized the worsening supply outlook, while Rapidan Energy projects ongoing losses even with mitigation efforts [4]. The only real solution, according to commentary in Nikkei Asia, is the return of peace to the Middle East, but the timing remains highly uncertain after the U.S. president's speech [2].
CONCLUSION
The closure of the Strait of Hormuz amid the U.S.-Iran conflict has triggered an unprecedented oil supply shock, sending energy prices soaring and forcing Asian economies to adopt emergency measures. Market volatility is expected to persist as negotiations continue and the risk of further escalation remains high. The outlook for energy supplies and regional economies will hinge on the resolution of the conflict and the reopening of the vital shipping route.
