KUALA LUMPUR, 22 JULY 2026 —
China’s state-backed buying has lifted the mainland’s US$15 trillion stock market, with technology and semiconductor stocks leading the rebound after authorities moved to restore confidence.
Market Impact
China Securities Regulatory Commission chairman Wu Qing told reporters the regulator would “keep a transparent, fair and open market order to let investors share the benefits of economic growth and the high-quality growth of the capital market.” According to the South China Morning Post, the intervention aims to restore middle-class confidence after the property slump weakened domestic consumption and after volatile artificial intelligence and Iran war headlines rocked trading.
The State Council started purchases in late June when the Shanghai Composite fell to 3,200 points, providing a floor that added about 15% to the index by late July. Semiconductor maker SMIC rose 28% in the same period, while Nasdaq-style STAR Board tech names climbed roughly 22%. The rebound contrasts with the 2.1% drop in the MSCI World Information Technology Index over the period.
Analysts said the programme channels scarce capital into strategic sectors the government wants for its next economic phase. “The state is using the market to fund the shift from property to tech-led growth,” said a Shanghai-based portfolio manager quoted by the SCMP. The official second-quarter GDP print of 4.3% missed the forecast, but exports grew 8.6% and high-tech manufacturing expanded 6.4%, offsetting some of the drag.
The intervention model differs from US practice. “In China, the government views financial markets as policy tools, so stabilising them is considered part of its mandate,” said a senior economist at a Beijing think-tank. In Washington, direct buying is confined to crisis moments such as March 2020, when the Federal Reserve stepped in to restore liquidity. Chinese officials, by contrast, frame the current purchases as routine fine-tuning.
Hong Kong’s Hang Seng Tech Index has gained 10% since late June, reflecting spill-over benefits from the mainland’s stabilisation. One Hong Kong broker said: “Mainland buying is lifting sentiment across the border, especially for dual-listed tech names.”
Not all observers are convinced the support will last. “Once the buying stops, volatility is likely to return,” cautioned a Singapore hedge-fund manager. The State Council has not set an end-date for the programme and has only said purchases will continue “as needed.”
