Japan Morning Briefing: What to Watch on July 23, 2026

Tokyo investors face a cautious start to Thursday’s session as geopolitical tensions in the Middle East and mixed overnight Wall Street performance set a risk-off tone. With the yen weakening further against the dollar, exporters may find some support, but broader market sentiment remains fragile amid escalating regional conflicts.

Wall Street Closes Mixed Amid Geopolitical Concerns

U.S. markets ended Wednesday’s session with modest losses, as the S&P 500 slipped 0.12% to $747.41 and the Nasdaq 100 declined 0.51% to $705.35. The Dow Jones remained nearly flat, down just 0.01% at $521.47. Technology stocks led the decline following Amazon’s job cuts in its artificial intelligence unit, while healthcare gained ground on Johnson & Johnson’s robotic surgery system approval.

Geopolitical risks dominated headlines as Yemen’s Houthis reportedly targeted Saudi tankers and Iran allegedly struck CIA facilities, raising questions about Russian involvement. These developments, combined with the return of U.S. soldiers killed in Iran, have heightened Middle East tensions that could impact global risk appetite.

Yen Weakness Supports Export Outlook

USD/JPY continues its upward trajectory, reaching ¥163.01 in early Asian trading. This sustained yen weakness provides a tailwind for Japan’s major exporters, with Toyota, Sony, and other multinational corporations likely to benefit from improved overseas earnings translation. However, the weak yen also raises concerns about import costs and potential Bank of Japan intervention.

Key sectors to watch include automotive stocks, given the Senate panel’s advancement of legislation that could restrict Chinese auto companies like Mercedes-Benz from U.S. markets. Japanese automakers may benefit from reduced Chinese competition. Technology and healthcare names could also see volatility following overnight sector moves in New York.

NISA investors should monitor defensive sectors as geopolitical uncertainty persists, while traders eye the ¥163 level as a potential intervention threshold.
