Japanese stocks closed at their highest ever level on May 22, 2026, as optimism grew that the U.S. and Iran are nearing a peace agreement, boosting investor confidence and driving a rally in the market.
The Nikkei Stock Average ended the day at 63,339.07, up over 1,600 points from previous sessions, marking a record high. The rally was primarily driven by gains in the technology sector, with SoftBank and other tech giants contributing significantly to the upward momentum. This surge follows reports of ongoing diplomatic negotiations between the U.S. and Iran, which have increased market optimism about a potential easing of geopolitical tensions that have historically affected global markets.
Market analysts note that the positive sentiment is also supported by broader macroeconomic factors, including stable commodity prices and easing concerns over inflation.
