Two claims tend to follow any headline about Singapore office rents: that the gains rest on a flood of fresh demand, and that Hong Kong is winning back the regional crown. A Stacked Homes article of 13 October 2026, drawing on quarterly data from a research house, puts both to the test, along with two other common assumptions.
Myth. The research house cited by Stacked Homes credits limited supply more than any sharp rise in demand. By its count, core CBD Grade A rents rose 1.8% quarter on quarter in 3Q2026 and 6.1% year on year, while vacancy in the segment slipped to 2.7% from 3.3%. The CBD has added no major Grade A tower since 2024, and the next one, Newport Tower, is due in 2027. Leasing shows no structural deterioration, the research house adds, though occupiers weigh their space needs carefully.
Largely a myth, because the two cities no longer chase the same role, Stacked Homes argues: Hong Kong serves as the gateway for mainland Chinese capital, while Singapore draws technology and AI firms as a regional hub. Hong Kong's Central Triple A rents jumped 15.0% year on year, yet that figure covers Central's top tier only. Across Hong Kong's whole prime market, rents gained 1.3% quarter on quarter in 2Q2026 and remained 42.7% under their 1Q2019 peak, according to Stacked Homes. A research house read the Central rebound as banks and other financial institutions moving into premium space, not a broad recovery.
Myth again. Fringe Grade A, core CBD Grade B and fringe Grade B rents grew between 5% and 9% year on year depending on segment, the research house cited by Stacked Homes reported. Prime CBD rents have risen since bottoming in 1Q2021, even as IOI Central Boulevard Towers opened in 2024.
Myth. Stacked Homes describes flexible co-working as a frequent first step before tenants trade up, a flight to quality. OpenAI is reportedly leaving co-working premises for the newly completed Shaw Tower with about 100,000 sq ft, according to Stacked Homes. Technology firms and non-bank financial companies, fintechs included, form most new-to-market demand.
