A growing number of Hong Kong millionaires are considering the mainland Greater Bay Area (GBA) cities as part of their retirement and later-life planning, including healthcare access, housing, and lifestyle. However, many have yet to fully address the financial and practical demands of maintaining residences across both Hong Kong and the mainland, according to the “OCBC Premier Banking – Hong Kong Millionaires Dual Living and Wealth Management Study 2026.”

Conducted in April 2026, the survey included 1,375 Hong Kong residents aged 35 to 65, each holding at least HK$1 million in liquid assets. About 30% of respondents who are either considering relocation to mainland GBA cities or already living across Hong Kong and the mainland—and who are not yet retired—reported gaps in their dual-living and retirement planning.

Respondents estimated needing over HK$10 million in liquid assets on average for retirement, with this figure rising to approximately HK$11.2 million among those not yet retired and living or planning to live in two locations.

Healthcare considerations are significant: among those living across two locations or contemplating relocation, 74% would consider advanced diagnostics and screening services in the GBA, 68% routine and preventive care, and 67% complex or long-term treatment.

The dual-living lifestyle also presents challenges. Nearly half (48%) of those already living in two locations cited increased cost pressures, 45% noted transport and coordination burdens, and 34% reported difficulties managing responsibilities across both places.

Josephine Lee, head of consumer financial services at OCBC Hong Kong, stated the bank aims to leverage its regional network and wealth management expertise to support customers in achieving their goals of wealth preservation, retirement planning, and investment growth while navigating their dual-living arrangements.
