The Hang Seng Index fell 1% on Thursday as financial stocks slumped on proposed rules restricting mainland Chinese funds in Hong Kong accounts.

The Hang Seng Index fell 1% as financial stocks slumped on new rules restricting mainland Chinese funds in Hong Kong accounts.
"The proposed restrictions directly target the cross-border capital flows that have been a key growth driver for Hong Kong's banking sector," said Victor Cheung, Hong Kong equities analyst at Edgen.
HSBC fell 3.9%, Standard Chartered slid 5.6% and Prudential dropped 6.5% — all London-listed financial groups with significant exposure to Hong Kong and mainland China. The selloff in financials dragged the broader index lower, with banking and insurance sectors among the worst performers. The Hang Seng Tech Index also declined, tracking the broader market weakness.
The proposed rules, if implemented, could curb the flow of mainland Chinese capital into Hong Kong's financial system, potentially reducing fee income and deposit bases for banks with large wealth management operations in the city. Mainland Chinese clients account for a significant portion of private banking assets at HSBC and Standard Chartered's Hong Kong units, according to company disclosures.
The decline in Hong Kong came as Asian markets broadly weakened. South Korea's Kospi tumbled 5.1% to 8,185.62, while Japan's Nikkei 225 slipped 1.4% to 66,532.35. The Shanghai Composite bucked the trend, rising 0.4% to 4,075.31.
The new regulations, reported by the Wall Street Journal, would restrict mainland Chinese investors' use of Hong Kong bank accounts, targeting a channel that has funneled billions of dollars into the city's financial system. The move adds to a series of regulatory measures aimed at controlling capital outflows from China, following similar restrictions on outbound direct investment and cross-border wealth management products.
In currency markets, the offshore yuan traded near 7.25 per dollar, while the Hong Kong dollar remained pegged at the weak end of its trading band. U.S. 10-year Treasury yields stood at 4.48%, providing little relief for rate-sensitive sectors. Brent crude held above $95 a barrel, adding to inflationary concerns across the region.
Trading volume on the Hang Seng Index was elevated compared with the 20-day average as investors reacted to the regulatory news. Southbound Stock Connect flows showed net selling of Hong Kong stocks by mainland investors, adding to the selling pressure.
The regulatory tightening raises questions about Hong Kong's role as a gateway for Chinese capital. The city has long served as the primary offshore center for mainland Chinese wealth, with banks earning substantial fees from cross-border wealth management and private banking services. Any reduction in capital flows could pressure earnings for Hong Kong-exposed financial institutions in the coming quarters.
