With the exit of non-compliant retail investors' funds, the pricing of new stocks will rely more on the judgment of institutional investors, leading to a weakening of the "retail premium" component in the issuance pricing, and the level of marketization is expected to increase.
On May 22, the Securities and Futures Commission of Hong Kong issued new account opening regulations, further tightening account opening review standards. Market participants are more concerned about how the new regulations for opening Hong Kong stocks accounts will reshape the underlying logic of cross-border investment, rather than the policy itself. From an industry perspective, the Hong Kong stock account opening industry chain, which has long operated in a gray area, is being thoroughly cleaned up and uprooted. Some industry insiders have bluntly stated, "The era of low-cost arbitrage and easy profits is over." In the past few years, mainland funds flowed into Hong Kong stocks, and the new share market once presented a lively scene of mass participation. However, with the increase in compliance thresholds, the future pricing of Hong Kong stocks will return more to professional institutions, shifting from widespread participation in new shares to professional pricing. What are the key points of the new account opening regulations in Hong Kong? The circular issued by the Securities and Futures Commission of Hong Kong to licensed corporations on May 22 was made after reviewing the account opening practices of 12 securities brokerages. Significant deficiencies identified in the review were focused on three dimensions: inadequate due diligence of account opening documents, acceptance of suspicious or forged documents during account opening, and weak monitoring of cross-border agency relationships with overseas intermediaries. In response to this, the Hong Kong regulator has put forward four rigid requirements for all licensed corporations: First, initiate internal self-inspection immediately. All licensed institutions must quickly conduct retrospective reviews, and if problematic documents were used during account opening, they must be actively cleared. Second, "lock" mainland investor accounts. Accounts opened with suspicious or forged documents should be closed directly; dormant accounts with zero balances should also be cleared. New account openings must meet the "three-piece set," including a written investor declaration, funds can only be accessed through a qualified bank account in the client's own name, and the bank must be on the approved list in Hong Kong. Third, redraw the red line for cross-border business expansion. The Hong Kong regulator explicitly reminds licensed institutions that when providing services to investors outside of Hong Kong, they must comply with the laws and regulations of both Hong Kong and the jurisdiction where the investor is located. This means that what is not allowed by mainland regulators is also not allowed to be circumvented in Hong Kong. Fourth, individual investor responsibility. The Hong Kong regulator has warned in a rare move using the Criminals Ordinance that using false documents for account opening may constitute a crime, the account will be terminated, and individuals' actions may be reported to law enforcement agencies. Dr. Yip Chi Hang, Executive Director of the Intermediaries Supervision Department of the Securities and Futures Commission of Hong Kong, said, "Licensed corporations should not sacrifice the 'know your customer' standard when expanding their business. The Securities and Futures Commission has a zero-tolerance attitude towards serious monitoring errors during the account opening process and the use of forged documents, and will take resolute regulatory and enforcement actions against relevant licensed corporations and their senior management to maintain a fair and competitive market environment." Tightening the gray account opening channel, the industry chain faces a comprehensive cleanup With the gray outflow channel blocked, a more crucial issue comes to the fore: where can the mainland funds that have previously allocated overseas assets through these channels go in the future? The answer has already been implied in the regulatory documents: the Stock Connect, Qualified Domestic Institutional Investor (QDII), and Cross-border Wealth Management Connect and other legitimate channels will become the only correct solution for conducting overseas investments. From a market perspective, the long-term positive effects are more evident, mainly in three aspects. Firstly, the return of funds will enhance A-share liquidity. With the gray outflow channel blocked, existing funds will gradually sell off and return to the mainland within two years, with some funds being reallocated through the Stock Connect, QDII, mutual funds, and other compliant channels. This will provide a more solid foundation for A-share liquidity. Secondly, local brokerage firms and the Stock Connect will benefit. The brokerage businesses and wealth management shares of the top local brokerage firms in Hong Kong are expected to increase. Additionally, mainland funds looking to allocate overseas assets will flow more towards stocks listed on the Stock Connect and related ETFs, increasing the demand for core asset allocation. Thirdly, market stability will be enhanced. With the regulatory loop formed, the risks of cross-border manipulation, capital outflow, money laundering, etc., will decrease, and the operating environment of the A-share market will become more stable. In conclusion, the new account opening regulations in Hong Kong are not intended to cut off normal cross-border investment channels but to focus on rectifying irregularities in the gray areas and guiding funds to flow orderly within a compliant framework. For investors, the continuous expansion and improvement of formal channels such as the Stock Connect, QDII, and Cross-border Wealth Management Connect are the stable and reliable path for long-term overseas asset allocation.
