Japan’s Nikkei 225 index climbed during Thursday’s trading session (October 22, 2026), buoyed by an improvement in investor sentiment toward global stock markets. The Tokyo benchmark index rose by approximately 0.3% to reach 64,828.16 points, extending a recovery following a period of pressure driven by inflation concerns and geopolitical uncertainty. Gains on Wall Street provided an additional boost to Japanese investors, particularly regarding technology stocks.
Optimism surrounding the artificial intelligence (AI) sector has re-emerged as a key market driver, following earnings reports from U.S. technology firms that helped alleviate concerns regarding the sustainability of AI-related investments. Shares of BayCurrent and Nomura Research Institute rose by approximately 5.0% and 4.4%, respectively, reflecting growing investor interest in companies linked to technology services and digital business.
Nevertheless, the index’s gains remain tempered by escalating geopolitical tensions in the Middle East. Concerns over potential U.S. military action against Iran have kept market participants cautious. Such uncertainty could trigger a renewed surge in global oil prices, intensify inflationary pressures, and cloud the economic growth outlook for energy-importing nations like Japan.
Investors are now closely monitoring developments in the Middle East, the trajectory of Wall Street, and upcoming Japanese inflation data scheduled for release on Friday (October 23, 2026). These factors could influence expectations regarding the Bank of Japan’s monetary policy and determine the sustainability of the Nikkei’s recovery. Should sentiment toward the technology sector remain positive and geopolitical tensions subside, the Japanese stock market may well sustain its gains in the near term. (CP)
