Accounting giant Deloitte said on Tuesday a majority of the single-family offices (SFOs) operating in Hong Kong were looking to increase their investments here.

According to Deloitte, the city was home to 3,384 SFOs at the end of 2025, an increase of 25 percent over two years.

A study by the firm found that SFOs contributed around HK$12.6 billion to the city's economy each year through operating expenditure alone, while employing more than 10,000 full-time professionals.

SFOs are private dedicated entities serving one wealthy individual or family by managing their investments, succession planning and philanthropic activities.

Deloitte Private's Hong Kong leader Anthony Lau noted that while the most of the new SFOs are from the mainland and Hong Kong, there was also interest from affluent regions around the world.

"Because of the various initiatives from the government, as well as its Go Global initiative, we also see that there are high-net-worth individuals coming from Europe, the rest of Asia-Pacific, US and Middle East to Hong Kong to set up single family offices as well," he said.

Roy Phan, Deloitte China Hong Kong international tax partner, noted that a key theme among the SFOs is that they are refocusing on Hong Kong amid global financial market uncertainties.

While 19 percent of SFOs surveyed said they planned to cut exposure to the US, 60 percent said they would increase exposure in the SAR in the coming three years, partly due to the city's booming stock and initial public offering market.

And about 26 percent aimed to increase exposure to the mainland thanks to the rise of the country's tech sector.

"Basically, AI and data science industry stands out as 60 percent of respondents say they intend to invest into this industry," Phan said.

"And 40 percent of the respondents from the SFOs indicate that they would increase their investments into three other sectors, including life and health technology, fintech, and the advanced manufacturing and new energy sectors."

In a statement, Secretary for Financial Services and the Treasury Christopher Hui said the family office industry and the asset management sectors were undergoing a "rapid evolution", with a greater focus on sustainable growth, inter-generational legacy, and positive impact.

"Under the 'One Country, Two Systems' framework, Hong Kong, with its advantages of being backed by the motherland and connected to the world, provides a favourable environment which is both predictable and has high potential for family offices to grow," he said.

Hui added that the government would continue to drive growth in the sector through the introduction of multiple measures, including tax benefits and implementation of the New Capital Investment Entrant Scheme.

The study, commissioned by government promotion arm InvestHK, includes surveys with 136 market participants across the city's family office industry, including 85 SFOs and 36 multi-family offices, between October and December.
