Chinese stocks advanced on August 31, with broad gains across the Shanghai and Shenzhen exchanges and a banking-led rally. The Shanghai Composite rose 0.86%, the Shenzhen Component 0.44%, the ChiNext 0.42% and the STAR Composite 1.9%, while more than 3,100 stocks gained. Combined turnover reached 2.15 trillion yuan, up 27.6 billion yuan, approximately $4.1 billion, from the previous session. Bank of China briefly reached a record HK$5.86, approximately $0.7475, and later traded at HK$5.815, up 4.21%; Postal Savings Bank of China rose 5.15% to HK$5.21, approximately $0.6646. The rally followed stronger-than-expected 2026 interim results from six major state-owned banks, all of which reported year-over-year growth in first-half net profit attributable to shareholders. Bank of China reported a 5.1% increase in first-half net profit and raised its interim dividend 8.8%. AI, media and entertainment, coal and banking stocks also gained, while property developers and gold-related shares declined. Analysts cited credit growth, higher non-interest income, disciplined credit-cost management and demand for high-dividend, low-valuation stocks, but cautioned that rapid sector rotation, third-quarter net interest margins, real estate asset quality and possible policy measures could limit further gains.
