Opinion: Talk of Private and Resale HDB Markets Decoupling Could Spark Buyer Frenzy
Opinion | August 12, 2026
NUS Provost’s Chair Professor Sing Tien Foo argues that the recent divergence between HDB resale and private housing price indexes should not be mistaken for structural separation. The two markets remain linked through overlapping buyer pools, household upgrading and downgrading, and shared fundamentals. Misplaced fears of decoupling risk encouraging fear-driven buying.

Three Quarters of Divergence Does Not Mean Structural Decoupling
The HDB resale price index fell by 0.3 per cent in the second quarter, marking a third consecutive quarterly decline. Over the same period, the private residential property price index rose by 0.5 per cent, extending a seven-quarter run of price growth, albeit at a slower pace.
Nearly a third of property sector veterans surveyed by the Institute of Real Estate and Urban Studies at NUS believe that both markets are structurally decoupling. But the evidence suggests otherwise.
AsianPrime Perspective: Professor Sing’s analysis is a timely reminder that headline index movements can mislead. Three quarters of divergence in a market that has shown remarkable synchronicity over two decades is not enough to declare a structural break. Buyers who rush in based on fear of “missing out” on private property may find themselves on the wrong side of the cycle.
Economists describe the relationship between public and private housing as cointegration: prices may drift apart temporarily, but remain anchored by common fundamentals and shared buyer behaviour over time. The three quarters of divergence and the private markets do not prove this, and less so when you consider that both indexes over the last two decades show remarkable synchronicity.
Interconnected Segments and Residential Mobility
Singapore’s housing market is better characterised as a hierarchy of interconnected segments, rather than two mutually exclusive markets. The hierarchy exists both in terms of housing type and price: at one end are BTO or resale HDB flats, while at the other are landed homes and good class bungalows.
Residential mobility further reinforces these linkages. Many young households begin with subsidised BTO flats. After fulfilling the minimum occupation period, they may sell their first home and use the accumulated housing equity to finance the purchase of a larger resale flat or a private condominium, creating a “ripple effect” between the two markets.
AsianPrime Perspective: This upgrader pathway is something we see daily in our client consultations. A household earning around S$10,000 a month may be choosing between a BTO flat, a resale HDB, an executive condominium, and an entry-level mass-market private condo. These overlapping buyer pools are what transmit price movements between adjacent housing segments.
Also notable is that neither market is homogeneous. The recent second-quarter growth for 2026 has been driven largely by landed housing and non-landed private housing in the Core Central Region, while other private housing segments have recorded much weaker performance.
Fear-Based Buying and the Lesson from Shorter Holding Periods
The greater risk is that misplaced fears of decoupling encourage fear-driven buying. Recent private residential launches with exceptionally strong take-up rates have reinforced concerns that buyers may be priced out if they do not act quickly.
An analysis of transactions involving private non-landed homes sold twice over a specific period suggests buyers have been holding properties for progressively shorter periods. The average holding period fell from around 120 months for homes bought in the early 2000s to less than 10 months for homes purchased between 2020 and 2025.
AsianPrime Perspective: The data on holding periods is striking. Buyers who entered during the post-pandemic boom earned average holding-period gains of just 0.95 per cent, compared with 47.2 per cent for those who bought during the weaker market conditions of the early 2000s. The lesson is clear: rising markets do not guarantee superior investment outcomes, and buyers should base decisions on affordability and long-term consumption needs rather than short-term capital gains.
Frequently Asked Questions
Are Singapore’s HDB and private housing markets decoupling?
According to NUS Professor Sing Tien Foo, the evidence does not support structural decoupling. The two markets remain linked through overlapping buyer pools, household upgrading and downgrading, and the expectation that homes preserve wealth over time. Three quarters of divergence should not be mistaken for permanent separation.
What is cointegration in the context of housing markets?
Economists describe the HDB and private housing relationship as cointegration, meaning prices may drift apart temporarily but remain anchored by common fundamentals and shared buyer behaviour over time. Short-term price movements should not be mistaken for structural separation.
Why is fear-based buying risky?
Analysis shows that buyers who entered the market during the post-pandemic boom earned average holding-period gains of just 0.95 per cent, compared with 47.2 per cent for those who bought during weaker market conditions in the early 2000s. Rising markets do not guarantee superior investment outcomes.
How have holding periods changed for private homes?
The average holding period fell from around 120 months for homes bought in the early 2000s to less than 10 months for homes purchased between 2020 and 2025, suggesting increasingly speculative buyer behaviour.
Should buyers rush to buy private property now?
Professor Sing advises that the recent divergence between HDB and private residential prices should be interpreted with appropriate caution. Buyers should base housing decisions primarily on affordability and long-term consumption needs rather than expectations of short-term capital gains or fear of missing out.
