Mainland China, Hong Kong premium office supply to peak as demand lags, Cushman says

Prime office supply in mainland Chinese cities and Hong Kong is estimated to peak this year, while demand remains hampered by an economic slowdown and global uncertainties, according to Cushman & Wakefield.At the end of 2025, premium office inventory in 21 major cities in Greater China – including Hong Kong, Beijing, Shanghai, Shenzhen and Guangzhou, as well as Taiwan – amounted to 99.2 million square metres (1.07 billion sq ft), up 4.6 million square metres or 8.4 per cent from a year earlier, the property consultancy said in a report on Wednesday.Demand failed to keep pace, with total office net absorption rising only 2.3 million square metres, pushing overall vacancy rates across the region up by 1 percentage point to 25.4 per cent over the period, it added.Hong Kong, Shanghai and Shenzhen recorded some of the largest numbers of multinational firms leasing prime office space in 2025, accounting for about one-fifth to more than half of the total deals.Prime office rents declined between 3.9 per cent and 16 per cent in 2025 in gateway markets, with Beijing seeing the largest retreat, the report showed.An aerial view of Guangzhou.
