On May 29, 2026, the Nikkei 225 rallied sharply to snap a three-day losing streak, surging 1,636.38 yen to close at a fresh historic high of 66,329.50 yen. Following the gains on Wall Street from the previous session, broad-based buying flooded the Tokyo market, particularly targeting technology and electronic component shares. Investor sentiment was significantly boosted by media reports indicating that negotiations between the United States and Iran toward ending their conflict were making tangible progress, which greatly alleviated lingering geopolitical anxieties. During intraday trading, the benchmark index extended its gains by over 1,700 yen, briefly breaching the 66,400 threshold. The broader TOPIX also recorded a substantial gain, rising 55.16 points to end at 3,957.17, underscoring the broad market strength.
