Chinese authorities have tightened restrictions on overseas stock trading, catching investors like Stephanie Peng off guard with new verification requirements. The crackdown comes as SpaceX IPO details emerge, expected to ignite massive interest in US tech stocks. Beijing aims to limit citizens' exposure to US equity markets, with regulators demanding investments only through official channels despite strong demand.

The CSRC has fined three brokerages—Futu Holdings, Tiger Brokers and Longbridge—for providing unlicensed cross-border services. Hong Kong authorities followed suit with warnings and reviews of 12 additional firms. As much as $32bn of mainland investor assets may face curbs, with existing investors limited to selling positions but unable to buy new shares during a two-year transition period.

Affected investors are exploring alternatives including moving assets to other jurisdictions like Singapore or the US. While some perceive the crackdown as bearish for US assets, others see opportunities with reduced competition for IPO allocations. The move highlights China's ongoing efforts to control capital outflows amid a struggling property market and limited domestic investment options yielding less than 2%.
