Japan's Nikkei ends the week down 6.4 percent as chip selloff and war weigh on Asian stocks

Japan's Nikkei 225 fell 5.8 percent to 62,946 on Friday, July 17, 2026, ending the week down 6.4 percent. A selloff in chipmakers and AI-related shares, alongside worries over the US-Iran war and surging oil prices, weighed on the market.

Taiwanese shares also dropped more than 5 percent, and MSCI's broadest index of Asia-Pacific shares outside Japan slid more than 2 percent. India held up better: Mumbai's Sensex traded up about 0.6 percent and the Nifty about 0.5 percent on Friday.

The Hormuz-driven oil surge and inflation worries have sharpened risk aversion across Asian markets.
