Japan's Nikkei fell 1,713.40 points, or 2.65%, at the close of trading on 22 October 2026, with losses concentrated in technology stocks, according to Nikkei Indexes data. The index closed at 62,907.84 points, its lowest level of the session, as semiconductor stocks faced heavy selling. It had reached an intraday high of 64,866.44 points before ending trading at its daily low. Declines extended to 141 constituents, according to the provider's daily summary. Meanwhile, 81 stocks rose and 3 were unchanged, leaving decliners ahead of advancers in a session marked by broad losses and weakness in technology constituents.
Technology accounted for the bulk of the pressure on the index, single-handedly subtracting 1,270.27 points from its daily change, according to Nikkei's sector contribution breakdown. Information and communications added further pressure, subtracting 237.90 points. The scale of the contribution reflects technology's heavy weighting in the index, with the sector accounting for 40.87% during the session. Information and communications had a weight of 11.05%, making movements in the two sectors influential in the Nikkei's direction. Among individual companies, Advantest had the largest weighting at 11.10%, according to the same summary, reflecting the substantial presence of technology companies in the index.
In the chip sector, the Nikkei Semiconductor Stock Index closed at 20,798.24 points, according to the provider's data. Its daily decline was 5.28%, exceeding the main index's percentage loss. The pressure on technology stocks came amid concerns over growing financial commitments linked to artificial intelligence investment, highlighted in Reuters' coverage of Asian markets. The agency said Meta's plan to issue non-voting Class C shares had reignited those concerns. Reuters described the focus of concern as "growing capital expenditure commitments", with the financing of these investments returning to the forefront of investors' attention.
Alongside the equity losses, the Nikkei Volatility Index rose 16.60% to 35.97, according to Nikkei Indexes data on 22 October. The selloff spread to other Asian markets, with South Korea's Kospi losing 3.5%, according to the Associated Press. In Hong Kong, the Hang Seng Index fell 3% during the session covered by the agency. In global energy markets, Brent crude jumped 4% on the same day. Its price reached $113.17 a barrel as fears of war with Iran intensified, according to the Associated Press, with rising oil prices accompanying declines in Asian stock indexes.
On Japan's economic backdrop, September trade data showed exports rising 16.7% year on year, according to Reuters. Growth slowed from a 19.3% increase in August, while overseas sales continued to expand. The trade balance recorded a deficit of 536.6 billion yen in September. The shortfall was larger than expectations of 181 billion yen, according to figures reported by the agency. It narrowed, however, from a deficit of 1.1 trillion yen in the previous month, leaving the report showing a monthly improvement in the balance alongside a weaker-than-expected result. On export demand, Reuters said "strong global investment in artificial intelligence continued to support exports of semiconductors and related equipment", placing the sector among the sources of support for Japanese trade.
