On June 5, Standard Chartered fell 3.12% in regular trading, trading at 204.8 HKD/share, with trading volume of 23.2347 million HKD. The decline follows reports that mainland Chinese residents now face significantly tighter restrictions on opening offshore accounts at major Hong Kong banks.

According to reports, the Bank of East Asia's Shanghai branch has stopped opening overseas investment accounts for mainland clients, while HSBC's Lujiazui staff confirmed that deposited funds must comply with Hong Kong rules. As a result, HSBC, Standard Chartered, and Prudential tumbled between 5% and 6.3% in London trading, with AIA Group dropping 6.8% in Hong Kong.

The regulatory tightening stems from the China Securities Regulatory Commission's joint crackdown on illegal cross-border securities trading, with the Hong Kong Monetary Authority requiring licensed institutions to strengthen account opening scrutiny for investors holding mainland identification documents. Banks must now obtain written declarations covering fund sources and document authenticity. Analysts note that while cross-border client securities services represent a relatively small share of total revenue, local Hong Kong banks face greater pressure than international peers due to higher reliance on cross-border client bases, with new customer growth expected to slow in the near term.
