Asian stock markets dropped sharply on Monday following escalating tensions between the United States and Iran, after President Donald Trump issued an ultimatum demanding the reopening of the Strait of Hormuz.
Major indices across the region recorded significant losses. Japan’s Nikkei 225 fell about 4%, while South Korea’s KOSPI dropped roughly 4.5%. Hong Kong’s Hang Seng Index also declined by around 2%, reflecting widespread investor anxiety.
The downturn comes amid fears of a deepening global energy crisis. Iran has threatened to target energy infrastructure across the region if military pressure intensifies, raising concerns about disruptions to oil and gas supplies. The Strait of Hormuz – through which about one-fifth of global energy exports normally pass remains a critical flashpoint.
Oil prices have surged dramatically since the conflict began, rising by more than 50%. Brent crude briefly climbed above $114 per barrel before easing slightly, with analysts warning prices could climb as high as $150–$200 if supply disruptions worsen.
The market reaction highlights growing uncertainty about the direction of the conflict and its economic consequences. Investors are increasingly worried about inflation, supply chain disruptions, and potential slowdowns in global growth if the crisis continues to escalate.
