The Nikkei 225 Futures (Dec 2025 contract) on the Osaka Exchange briefly touched the 50,000 mark at around 10:18 a.m. SGT on Tuesday, October 21, 2025, driven by optimism that Japan’s new coalition government will roll out policies to spur economic growth. However, profit-taking later in the session trimmed gains.
As of 21 October, the Nikkei 225 rose by 0.27% to close at 49,316.06; while the Topix index rose just 0.03% to 3,249.50. Both indices hit a new intraday record– with the Nikkei 225 hitting 49,945.95 while the TOPIX hit 3,274.06
In the currency market, the U.S. dollar strengthened past the ¥151 level as investors sold the yen, typically viewed as a safe haven, following the rally in Japanese equities. At midday, the dollar traded at ¥151.10–¥151.14, compared with ¥150.71–¥150.81 in New York overnight. The euro was quoted at $1.1633–$1.1635 and ¥175.79–¥175.86.
The continued rise in equities came ahead of Sanae Takaichi’s expected election as Japan’s new prime minister later in the day, following her coalition agreement with the Japan Innovation Party. Analysts noted that while markets had largely priced in the new government, expectations of political stability and expansionary fiscal policies spurred additional buying.
Investor sentiment was further lifted by easing concerns over U.S.-China trade tensions, after President Donald Trump expressed optimism about reaching a “fantastic deal” with Chinese President Xi Jinping in their upcoming meeting.
