Asian stocks fell sharply on Friday, September 11, 2026, as WTI and Brent crude rose above $100 a barrel, long-term U.S. Treasury yields approached 5% and investors awaited the August U.S. Consumer Price Index, the Federal Reserve’s September 15-16 meeting and the Bank of Japan’s policy decision. The MSCI Asia Pacific index fell 1.3%; the Nikkei 225 opened its afternoon session down 1,909.91 points at 63,361.04, while the KOSPI opened 3.29% lower at 6,802.50 and later traded about 2.4% lower. Hong Kong’s Hang Seng declined about 0.8%-1.5%, Shanghai fell approximately 1.8% or more than 2% in different readings, and India’s BSE Sensex dropped about 1.0%, or 710 points, to 74,188. Semiconductor stocks led declines after a strong artificial-intelligence-driven rally. Indian equities were also pressured by foreign fund outflows, a rupee decline to 95.44 per dollar and concerns that higher oil prices would widen the import bill and fuel inflation. Oil prices were supported by tensions involving the United States, Iran, the Strait of Hormuz, the Red Sea and Iran-aligned Houthi forces, including reports of the seizure of Yemen’s port of Mocha. U.S. producer prices rose 0.4% in August and 5.4% year over year, while market-implied odds of a Federal Reserve rate increase rose to roughly 70%. AI infrastructure demand remained strong: Oracle reported a record $664 billion backlog, and Tencent-backed Shanghai Enflame Technology surged about 200% in its Shanghai debut after raising 6.12 billion yuan ($912 million). Other developments covered included Samsung’s campaign targeting iPhone loyalists, Ford’s planned $1 billion Kentucky Truck Plant paint-shop investment and former President Donald Trump’s proposed $5,000-per-adult dividend, which faced bipartisan opposition over a projected cost exceeding $1.2 trillion.
