Japan Morning Briefing: Geopolitical Tensions Grip Markets April 6

Tokyo investors face a tense Monday morning as geopolitical risks dominate global sentiment, with US-Iran tensions escalating and oil prices surging on supply disruption fears. The risk-off mood could weigh on Japanese equities despite Wall Street’s mixed but relatively stable overnight session.

US markets showed resilience Friday, with the S&P 500 edging up 0.09% to $655.83 and the Nasdaq 100 gaining 0.11% to $584.98, while the Dow Jones slipped 0.09% to $465.06. The modest moves masked underlying anxiety as investors digested reports of ongoing US-Israeli military operations against Iran and Trump’s ultimatum for Iran to reopen the Strait of Hormuz by Tuesday night.

Currency markets remain volatile with USD/JPY levels closely watched by Tokyo traders. Any yen strength could pressure Japan’s export-heavy Nikkei 225, particularly impacting automotive giants like Toyota and technology leaders such as Sony. Conversely, a weaker yen might provide some cushion for exporters amid the broader risk-off environment.

Today’s Tokyo session will likely center on three key themes: energy security implications for resource-poor Japan, defensive positioning ahead of potential Middle East escalation, and how domestic companies with Iranian exposure might react. Oil-related stocks and trading houses could see increased volatility as crude prices rise on supply concerns.

Sectors to watch include energy importers, which may face margin pressure, while defense-related stocks could attract safe-haven flows. Traditional defensive plays like utilities and consumer staples may outperform, making them attractive for NISA investors seeking stability during uncertain times. Technology exporters will depend heavily on currency moves and any signs of supply chain disruption.

With Trump’s Tuesday deadline looming, expect heightened volatility and potential safe-haven flows into the yen, creating a challenging environment for risk assets.
