Asian stock markets have plummeted in the wake of US President Donald Trump's ultimatum to Iran, warning it to reopen the Strait of Hormuz or face severe consequences. The warning has sparked widespread panic, with key indexes in Japan, South Korea, and Hong Kong experiencing sharp declines. Japan's benchmark Nikkei 225 and South Korea's KOSPI plummeted 4 percent and 4.5 percent, respectively, in early trading on Monday, while the Hang Seng Index in Hong Kong tumbled about 2 percent. Australia's ASX 200 dropped about 1.6 percent, and the NZX 50 in New Zealand dipped about 1.3 percent. The volatile oil market has seen prices surge, with futures for Brent crude, the international benchmark, rising more than 1.5 percent to top $114 a barrel before easing to about $112.

The Strait of Hormuz is a critical waterway, through which about one-fifth of global oil and natural gas exports usually transit. Tehran has pledged to completely close the strait and launch retaliatory attacks on energy and water infrastructure across the region if Trump follows through on his threat. The deadline for Trump's ultimatum is set to expire at 23:44 GMT on Monday. The escalating tensions have added to fears of a cascading global energy crisis, with oil prices surging more than 50 percent since the start of the war between the US and Israel.

The international community is bracing for the worst as the US and Israel's war on Iran approaches the one-month mark with no clear end in sight. The situation remains precarious, with the strait still being transited by a small number of Chinese, Indian, and Pakistani-flagged vessels.

The Trump administration's belligerent stance on Iran has sent shockwaves across global markets, with far-reaching consequences for energy prices and stability in the Middle East. The ultimatum has added to the already precarious situation, with oil prices set to soar even higher if the Strait of Hormuz remains closed. The international community must now navigate the treacherous waters of escalating tensions, with the risk of a full-blown conflict hanging precariously in the balance. The world waits with bated breath as the deadline for Trump's ultimatum draws near.
