Asian stock markets opened higher, boosted by tech sector support, despite continued US tariff risks.

Asian stock markets opened higher as investors continue to monitor President Trump's tariff stance after the US Supreme Court overturned the previous measure, only to immediately announce a 15% tariff on imports worldwide.

February 23, 2569 Asian stock markets opened in positive territory. Despite remaining uncertainties regarding U.S. tariffs,

The Hang Seng Index opened at 26,798.97 points, up 385.62 points or +1.46%, while Australia's S&P/ASX 200 edged up 0.17% and South Korea's KOSPI index surged 1.7% to an all-time high, driven by technology stocks such as SK Hynix, which climbed more than 3%, and Samsung Electronics, which gained 2%.

The Chinese stock market remains closed for the Lunar New Year holiday and will reopen tomorrow. The Japanese stock market is closed today in observance of the Emperor's birthday.

The investment climate was also influenced by the U.S. Supreme Court's ruling, which passed a 6-3 vote on February 20th to overturn President Donald Trump's tariffs, stating that the International Emergency Economic Powers Act (IEEPA) does not empower the president to impose tariffs because the law is intended solely for sanctions and capital controls in emergency foreign security situations.

However, just one day after the ruling, President Trump announced an immediate increase in import tariffs from 10% to 15% for all countries worldwide, citing that many countries had taken advantage of the United States for a long time without retaliation. This stance continues to send ripples through global financial markets.
