Asian stock markets experienced a robust relief rally on Wednesday following a ceasefire agreement between the United States and Iran, which ended a six-week conflict that had destabilized energy markets and investor confidence. The ceasefire announcement, which included a suspension of planned US attacks on Iranian infrastructure and a halt to Iran's defensive operations in the Gulf, eased fears of supply disruptions in the Strait of Hormuz. As a result, Hong Kong's Hang Seng Index opened 2.5% higher, reflecting positive sentiment from the derivatives market. South Korea's KOSPI led the gains with a 5.3% increase, largely driven by major semiconductor companies like Samsung Electronics and SK Hynix, which rose 7% and 9%, respectively. Japan's Nikkei 225 also saw significant gains, advancing approximately 4.6%. The broader MSCI Asia Pacific Index climbed 2.6%, and global futures, including those for the Dow Jones Industrial Average and S&P 500, rose sharply as lower oil prices alleviated inflation concerns and bolstered expectations for steady global growth.
