<div id="readability-page-1"><div>HSBC Global Investment Research published a report noting that the Hong Kong Monetary Authority and the Securities and Futures Commission have issued a circular requiring enhanced controls on account opening and ongoing due diligence for clients related to Mainland China. The circular was released shortly after the China Securities Regulatory Commission penalized three offshore brokerages on May 22, 2026. One notable requirement is that financial institutions should obtain written declarations from Mainland investors confirming that all funds used for investment activities are &#34;from legitimate sources outside Mainland China.&#34; This has raised concerns among different investor groups regarding how regulators will interpret and enforce the new rules. At a time when market expectations for growth in Hong Kong's wealth management business are already high, tighter regulation may dampen investor confidence in further upside in the short term until market data proves its impact.The broker stated that among Hong Kong financial stocks, it prefers BOC HONG KONG (02388.HK) +0.240 (+0.501%) Short selling $171.01M; Ratio 12.374% over HKEX (00388.HK) +1.000 (+0.250%) Short selling $356.86M; Ratio 13.572% and AIA (01299.HK) -0.450 (-0.547%) Short selling $1.23B; Ratio 25.853% . It expects banks to be less affected than capital market participants and insurers, as the latter two rely more heavily on cross-border client investment flows. For BOC HONG KONG, its capital return story, positioning in serving Chinese enterprises' overseas expansion, and demand linked to the growing internationalization of RMB usage provide support.HSBC Global Investment Research rates HKEX and BOC HONG KONG as Buy, with target prices of HKD528 and HKD53.2 respectively. It rates AIA as Hold, with a target price of HKD85. (ad/da)(HK stocks quote is delayed for at least 15 mins.Short Selling Data as at 2026-05-29 16:25.)</div></div>
