Did Civil Servants Buy Homes Near Unannounced MRT Stations?

A working paper published in September 2026 raised a question about private-home purchases near future Singapore MRT stations: were some buyers acting on information the public did not yet have? Its authors reported a statistical pattern, not proof of misconduct by any named officer. Singapore’s government is reviewing the matter. 101115

What the paper alleged

The authors found that people they classified as civil servants bought private homes near planned MRT stations at a disproportionate rate before the station locations were publicly announced. Compared with a matched control group, the difference was concentrated in the one to two years before announcement. The paper interpreted the pattern as consistent with purchases informed by non-public information. 1015

That interpretation has an important limit. A purchase near a future station does not, by itself, show that its buyer knew the station plan or that the plan influenced the decision. The government has described the paper’s result as a statistical association and cautioned against treating it as evidence about any particular officer. 11

How the authors identified buyers and made the comparison

The researchers assembled private-property transactions from Singapore legal filings and linked buyer information to civil-service identities. Reporting on their method says they compared buyer details with the Singapore Government Directory to identify people they classified as civil servants. They then examined purchases near planned stations and compared those buyers’ behaviour with that of a matched group treated as uninformed. 3910

The sources provided here do not establish that every employment match was independently verified or spell out the full construction of the control group. Those details matter when assessing how strongly the comparison supports the paper’s interpretation. 91011

Why academics challenged the acknowledgements

National University of Singapore professors Ivan Png and Jessica Pan said they knew nothing of the research and asked the authors to remove their names from the acknowledgements. Other acknowledged NUS academics also said they had not participated in the research; reporting suggested that comments attributed to them may have come from earlier seminars. Being thanked in the paper should therefore not be taken as an endorsement of its findings. 31

How the Public Service Division responded

On September 14, Singapore’s Public Service Division (PSD) said it was examining the paper’s data and methodology and would refer the matter to the Corrupt Practices Investigation Bureau if there was a material basis to do so. In a September 25 response, the government said it was reviewing purchases by relevant officers while emphasizing that the reported association could not establish whether an officer had access to non-public plans or acted on them. 711

The distinction is the central one: the paper identifies a pattern worth examining; determining whether any officer misused information requires evidence beyond the pattern itself. 1011
