Nikkei Falls 0.9% as Geopolitical Tensions Weigh on Tech Stocks

The Nikkei 225 declined 0.90% to close at 38,420 on Monday as geopolitical tensions in the Middle East and concerns over U.S. monetary policy weighed on investor sentiment across Tokyo markets. The broader TOPIX index fell a more modest 0.41%, while the yen weakened further against the dollar.

The USD/JPY pair strengthened 0.32% to ¥171.12, continuing its climb toward multi-decade highs and providing some support for Japan’s export-heavy sectors. However, this currency tailwind was insufficient to offset broader risk-off sentiment as investors digested escalating tensions in the Strait of Hormuz following reports of projectile attacks on tankers near the UAE’s Fujairah port.

Overnight developments in the Middle East dominated market psychology, with oil prices initially spiking before retreating after former President Trump indicated U.S. willingness to assist stranded vessels in the strategic waterway. The geopolitical uncertainty, combined with persistent inflation concerns affecting Federal Reserve policy expectations, created a challenging backdrop for risk assets globally.

Technology stocks bore the brunt of Monday’s selling pressure, with several major names posting significant declines. Kyocera tumbled 7.07% to ¥17.47, marking the session’s worst performer among major constituents. Industrial automation giant Fanuc dropped 2.35% to ¥21.64, while Sony Group fell 1.54% to ¥19.78, reflecting broader weakness in the tech sector amid concerns over global demand and supply chain disruptions.

Automotive heavyweight Toyota Motor declined 2.03% to ¥188.71, despite the weaker yen typically benefiting the export-oriented manufacturer. The decline suggests investors remain cautious about global automotive demand amid economic uncertainties. Financial services firm Orix also retreated 1.67% to ¥33.05.

Bucking the downward trend, SoftBank Group emerged as the day’s standout performer, surging 4.32% to ¥17.735. The technology conglomerate’s gains likely reflected investor optimism around its artificial intelligence investments and portfolio companies, providing a rare bright spot in an otherwise subdued session. Air conditioning manufacturer Daikin Industries also posted modest gains of 0.85% to ¥16.55.

The session’s mixed performance highlighted the ongoing tension between domestic monetary policy support and external headwinds. While the Bank of Japan’s ultra-accommodative stance continues to underpin market liquidity, investors remain sensitive to global risk factors, particularly geopolitical developments that could disrupt energy supplies and trade routes.

For NISA investors, Monday’s session served as a reminder of the importance of diversification across sectors and geographies. While technology stocks faced pressure, the resilience shown by certain industrial and telecommunications names suggests selective opportunities remain available for long-term investors willing to navigate short-term volatility.

Looking ahead, market participants will closely monitor developments in the Middle East and their potential impact on energy prices and global supply chains. The continued weakness of the yen, while supportive for exporters, also raises questions about the BOJ’s policy trajectory and its implications for domestic inflation dynamics.
