Japan Morning Briefing: What to Watch on May 26, 2026

Tokyo investors face a cautiously optimistic open Tuesday as geopolitical tensions in the Middle East create a complex backdrop for risk assets, despite overnight gains on Wall Street that suggest resilient investor sentiment.

U.S. markets closed higher Monday, with the S&P 500 advancing 0.39% to $745.64, the Nasdaq 100 gaining 0.42% to $717.54, and the Dow Jones posting the strongest performance with a 0.60% rise to $506.12. The modest but broad-based gains came despite escalating tensions between Israel and Hezbollah, suggesting markets are compartmentalizing geopolitical risks from underlying economic fundamentals.

The USD/JPY pair sits at ¥158.99, maintaining elevated levels that continue to benefit Japan’s export-heavy sectors. This exchange rate provides significant tailwinds for automotive giants like Toyota and technology exporters including Sony, whose overseas earnings receive a substantial boost when converted back to yen.

Today’s Tokyo session will likely focus on Middle East developments and their potential impact on energy markets and global supply chains. Iran’s reported willingness to reopen the Strait of Hormuz within 30 days of a peace deal, according to Nikkei sources, could influence energy-related positions. Meanwhile, Iran’s decision to restore international internet access signals potential diplomatic flexibility.

Export-oriented sectors should remain in focus given the favorable currency environment. Automotive, electronics, and machinery stocks may attract attention from both institutional and NISA investors seeking exposure to the weak yen theme. Energy and shipping companies could see volatility as traders assess Middle East supply route risks. Defensive sectors like utilities and telecommunications might appeal to risk-averse investors monitoring the geopolitical situation.

Watch for any corporate guidance updates that factor in the current exchange rate environment, particularly from companies with significant overseas exposure.
