With no legal mechanism for trading overseas stocks directly, mainland investors can access overseas capital markets only through a handful of government-approved channels.
These include the Qualified Domestic Institutional Investor (QDII) program, under which licensed domestic financial institutions invest overseas on behalf of clients. Also, the Shanghai-Hong Kong Stock Connect and Shenzhen-Hong Kong Stock Connect schemes allow eligible investors to trade a designated list of Hong Kong-listed stocks and exchange-traded funds (ETFs) through mainland brokers.
Another option is the Cross-boundary Wealth Management Connect scheme. First piloted in 2021, the program allows eligible residents to invest in approved financial products through participating banks. By August 2025, 14 securities firms had joined the scheme, although its reach remains largely limited to residents of the Guangdong-Hong Kong-Macao Greater Bay Area.
The recent crackdown makes it clear that China wants investors who previously relied on offshore online brokerages to migrate to these regulated channels. The implementation plan specifically encourages overseas investment through Stock Connect, QDII and the Wealth Management Connect scheme.
The shift could involve a sizeable amount of capital. Tian Liang, chief financial sector analyst at CITIC Securities, estimates that mainland clients affected by the crackdown hold between HK$150- 180 billion (US$19.1-23b) in assets at Futu and HK$45-50 billion (US$5.7- 6.4b) at Tiger Brokers. Including other affected brokerages, the total could reach HK$250 billion (US$31.6b).
Whether existing legal channels can absorb that demand remains a major question. As of June 2026, China had approved a cumulative US$176.2 billion in QDII investment quotas. But access to QDII products is constrained by foreign exchange quotas, fund capacity and risk management requirements, meaning subscriptions are often capped or suspended.
Stock Connect offers a more direct route to Hong Kong equities, but it too has limits. Investors can trade only eligible stocks and ETFs, southbound trading is subject to a daily quota of 420 billion yuan (US$58.5b), and individual investors generally must maintain at least 500,000 yuan (US$73,650) in securities and cash assets to qualify.
In a May 25 report, Kaiyuan Securities said rising demand may prompt regulators to broaden the slate of available securities through Stock Connect, increase QDII quotas and product offerings, and extend the geographic coverage of the Wealth Management Connect scheme.
Total approved quotas for QDII reached US$176.2 billion by June 30, US$5.3 billion more than at the end of June last year, according to the State Administration of Foreign Exchange. The People's Bank of China announced in early July the annual investment quota of Southern Bond Connect, an access for mainland investors to Hong Kong's bond market, would be raised from 500 billion yuan (US$73.5b) to 800 billion (US$117.7b).
