The rebound in Asian equities, particularly in AI and semiconductor stocks, is likely to boost global market sentiment and support tech-heavy indices. However, the suspected FX intervention and BOJ's hold may keep the yen and dollar volatile, while ongoing Middle East tensions could pressure oil prices and inflation expectations.
On July 31, 2026, Asian markets rallied sharply, led by South Korea's KOSPI which surged over 16% intraday, recovering from a steep selloff earlier in the week. The rebound was driven by strong earnings from Microsoft and Amazon (company), which eased concerns about AI-related capital spending. Samsung Electronics and SK Hynix jumped over 20% each, while Japan's Nikkei 225 rose about 5%. The Japan — Japanese yen remained in focus after suspected coordinated intervention by Japanese, South Korean, and possibly US authorities on Thursday, which had lifted the yen from 40-year lows. The Japan — Bank of Japan left rates unchanged, as expected, but one board member dissented in favor of a hike. Oil prices were volatile amid Middle East tensions, including a drone strike on gas vessels in Egypt's Damietta port, raising concerns about Egypt — Suez Canal shipping. Despite the rebound, the KOSPI was still set for its largest monthly loss since 1997.
