The Nikkei Stock Average climbed 5.1% to 57,033.88, having touched an all-time intraday peak of 57,337.07. The rally was fueled by projections from public broadcaster NHK showing Takaichi’s Liberal Democratic Party and the Japan Innovation Party securing a two-thirds supermajority in the lower house. This mandate provides the administration with significant leverage to implement a platform focused on defense, artificial intelligence, and nuclear fusion.

Technology and industrial heavyweights led the market's ascent. Chip-testing specialist Advantest soared 15%, while SoftBank Group and Hitachi Ltd. posted gains of 7.7% and 6.1%, respectively. Beyond the equity markets, the 10-year Japanese government bond yield rose to 2.275%, and the yen showed resilience, strengthening to 156.86 against the U.S. dollar.

Strategic Spending and Economic Rebalancing

Takaichi’s economic roadmap includes a pledge to reduce the national debt-to-GDP ratio while simultaneously stimulating growth through targeted tax relief. Analysts at Morningstar DBRS expect the administration to move quickly on campaign promises, such as a temporary suspension of the consumption tax on food to alleviate cost-of-living pressures. However, experts warn that the Prime Minister must navigate a fragile geopolitical landscape:

• Balancing deeper ties with the United States and regional allies.
• Managing a deteriorating trade relationship with China.
• Sustaining economic growth that exceeds the government's borrowing costs.

Elias Haddad, global head of markets strategy at Brown Brothers Harriman, suggested that concerns over fiscal profligacy are exaggerated. According to Haddad, Japan’s current trajectory of loose fiscal policy combined with tighter monetary controls remains fundamentally positive for the yen, provided that economic expansion continues to outpace debt service requirements.
