Japanese financial markets reacted with significant optimism in early Monday trade following a breakthrough in Middle East diplomacy. Nikkei 225 futures surged 3.4%, tracking a broader global rally sparked by the de-escalation of the conflict between Washington and Tehran. Simultaneously, the 10-year JGB futures rose 0.34 point to 128.81, as the prospect of stabilized energy prices eased some of the immediate inflationary pressures that had recently weighed on the bond market.
President Donald Trump announced on social media that the agreement with the Islamic Republic is "now complete," marking a potential end to the three-month-old war. Under the terms of the agreement, the Strait of Hormuz—a vital artery for 20% of the world's oil supply—will be reopened to international shipping without tolls. However, the President issued a stern warning that he would resume military strikes on Tehran if Iran fails to deliver on a final, comprehensive nuclear deal during the upcoming 60-day negotiating period.
Prime Minister Sanae Takaichi issued a statement strongly supporting the US-Iran agreement, noting that Japan has long advocated for "maximum flexibility" to secure a ceasefire. Takaichi, who recently described the strait as an "international public good" in the Financial Times, expressed hope that the deal would lead to permanent stability in the region. The Prime Minister's administration has been under pressure to secure energy supply chains as Japan's economy faced headwinds from the prolonged maritime disruption.
The deal reportedly includes an "immediate and permanent termination of military operations on all fronts," including the conflict in Lebanon. While Iranian Deputy Foreign Minister Kazem Gharibabadi confirmed the finalization of the memorandum of understanding, he noted that implementation would only begin after the official signing in Switzerland. Market participants are now closely watching for Israel's formal response, as the agreement was reached despite a flare-up in hostilities in Beirut just 24 hours prior.
Oil markets saw an immediate reaction to the news, with Brent crude futures sliding more than 3% in early Asian hours to approximately $83.88 per barrel. Analysts suggest that the reopening of the Strait of Hormuz could significantly lower global energy costs, providing a much-needed tailwind for technology exporters like Tokyo Electron (8035) and Advantest (6857), which saw significant gains in previous sessions on peace hopes. Banking giants such as Mitsubishi UFJ Financial Group (MUFG) and Mizuho Financial Group (MFG) are also expected to remain in focus as the Bank of Japan prepares for its upcoming policy meeting.
