Hong Kong’s financial services sector will require up to 5 million more square feet of office floor space over the next 10 years, driven by the growth of mainland Chinese banks, a new report says. The office space demand stems from the 55,000 jobs in financial services that may be added over the next decade, particularly in fund management related services, according to report from international real estate agency Jones Lang LaSalle (JLL) on Monday. Hong Kong has the most expensive office space in the world, but demand in the Grade A office market has been buoyed by financial institutions that can “pay above market rents across all locations”, the report said. As one of Asia’s largest financial hubs, Hong Kong’s finance sector has grown at a compound annual growth rate of 2.1 per cent since 2000, compared to 1.4 per cent for all industries. But headwinds such as low interest rate policies have forced Western banks to trim regional operations, with Goldman Sachs cutting nearly 30 per cent of its Asian investment banking jobs outside Japan, as mainland Chinese banks continue to grow. “Even as larger Western banks trim their operations in Hong Kong, the overall impact on the market will be dampened by the growth of mainland financial firms in the city,” said Denis Ma, head of research at JLL. Other demand factors for office space in the city include the growth potential of the city’s fintech and insurance industries, Ma and JLL’s head of Hong Kong markets Alex Barnes said in the report. Hong Kong’s office market will also see greater decentralisation as close to 70 per cent of all new Grade A offices in the next five years will be located in Hong Kong East or Kowloon East. Currently, financial services account for half of Grade A office space in Central. “As larger Western financial institutions move out or reduce their footprints in Central, much of the vacated space will likely be backfilled by mainland Chinese corporates,” said Barnes. Hong Kong’s office assets attracted US$1.68 billion in Chinese investment in the first half, down 9 per cent from last year, according to Knight Frank research. Office deals this year include Everbright Group paying US$1.29 billion for Dah Sing Financial Centre and Shanghai Electric paying US$27 million for an office building on Hong Kong Island.
