West Texas Intermediate crude futures rose 1.4% to $79.25 a barrel, while Brent crude climbed 0.85% to $84.01. The escalation centers on the Strait of Hormuz, where the U.S. intends to enforce a blockade targeting Iranian vessels and their customers. Vivek Dhar, an analyst at Commonwealth Bank of Australia, warned that the move creates a high incentive for Iran to retaliate, potentially leading to persistent attacks on commercial shipping.

Asian stock indices reacted sharply to the instability. Japan's Nikkei fell 1.0%, Taiwan's Taiex dropped 2.75%, and South Korea's Kospi slid 1.6%, largely driven by a 4.6% decline in SK Hynix shares. Currency markets remain equally volatile. Strategists at DBS Group Research noted that the Indian rupee, Indonesian rupiah, and Thai baht face mounting pressure as rising energy costs weigh on regional sentiment. While the Australian dollar held steady at US$0.6918, analysts suggest that any further decline in capital market confidence could trigger a significant correction for the currency.
