SEOUL / HONG KONG — Asian stock markets posted strong gains on Tuesday, July 21, 2026, breaking a three-day losing streak as diplomatic mediation efforts in the Middle East helped pull crude oil prices back from recent highs.
South Korea’s Kospi index surged sharply, driven by a heavy rebound in semiconductor and technology stocks, while investors across the region prepared for a crucial wave of corporate earnings that will test the health of the global artificial intelligence sector.
Global Market Summary
- Brent Crude Oil: Eased 0.38% to $88.88 per barrel, pulling back from a one-month high of $91.42 reached in the previous session following news of a 10-day ceasefire proposal between Washington and Tehran.
- Regional Stock Indexes:
- South Korea (Kospi): Climbed 2.2% to nearly 3%, recovering from recent selling pressure led by heavyweights like Samsung Electronics and SK Hynix.
- Japan (Nikkei 225): Added over 1.5%.
- MSCI Asia-Pacific Index (ex-Japan): Rose 0.25% following consecutive sessions of decline.
- Currencies & Yields: The U.S. Dollar Index remained firm at 100.96 due to safe-haven demand. The U.S. 2-Year Treasury yield held steady at 4.206%, with bond traders pricing in interest rate hike expectations later this year.
Ceasefire Hopes Cool Energy Markets
The pull-back in oil prices comes after reports that Tehran received a proposed 10-day ceasefire framework aimed at halting the conflict that erupted in late February 2026.
However, market strategists urge caution, pointing to active risks such as statements from Yemen’s Iran-aligned Houthis threatening a naval blockade against Saudi Arabia, which could further disrupt regional maritime logistics.
Market Commentary: “Investors are still trying to look at things with a glass-half-full view… But concern has to be growing that things could get out of hand if the conflict really escalates across the region.”

The Upcoming “AI Earnings Test”
Beyond geopolitical developments, global focus is shifting to Q2 earnings reports from tech giants like Alphabet and Intel.
Despite strong fundamental demand for hardware, high valuation multiples leave chipmakers and AI-related stocks vulnerable if revenue and profit projections show any signs of deceleration. Rising energy costs and interest rate uncertainties continue to complicate the macro outlook for capital-intensive tech companies.
