NextFin news, Asian stock markets surged to new record highs on Tuesday, September 16, 2025, with Taiwan and South Korea leading gains as investors positioned themselves ahead of a key U.S. Federal Reserve interest rate decision. The dollar retreated as market participants increasingly expected the Fed to announce its first rate cut of the year.
In Seoul, South Korea's KOSPI index rose 1.1% to 3,446.13, marking a fresh record high, while Taiwan's stock market also hit new peaks. Japan's Nikkei 225, after a holiday, briefly touched about 45,000 points before settling 0.3% higher at 44,904.13. Australia's S&P/ASX 200 edged up 0.2% to 8,871.30. Conversely, Hong Kong's Hang Seng declined 0.2% to 26,384.95, and China's Shanghai Composite fell 0.4% to 3,846.61.
The U.S. dollar weakened against most Asian currencies as investors anticipated the Federal Reserve's move to ease monetary policy. The dollar index fell, reflecting expectations of a rate cut to support economic growth. This sentiment was supported by positive economic data from various regions and ongoing trade negotiations between the U.S. and China.
Global markets were also influenced by mixed cues, including progress in U.S.-China trade talks. U.S. Treasury Secretary Scott Bessent announced that a framework deal had been reached regarding the ownership of the social video platform TikTok, with a potential finalization expected following a call between U.S. President Donald Trump and Chinese Premier Xi Jinping scheduled for Friday.
On Wall Street, the S&P 500 climbed 0.5% to a new all-time high, while the Dow Jones Industrial Average rose 49 points, or 0.1%, reflecting investor optimism ahead of the Fed's policy announcement.
Market analysts noted that the anticipation of the Fed's rate cut was a key driver behind the rally in Asian equities and the dollar's retreat. The expected easing of U.S. monetary policy is seen as supportive for global growth and risk assets.
These developments occurred amid ongoing economic data releases showing positive growth signals in various Asian economies, contributing to investor confidence. The combination of easing monetary policy expectations and improving economic fundamentals helped propel markets to new highs on this Tuesday.
