191 Officers Checked, Eight Referred to Police: An MRT Station Is Worth Most Before Anyone Knows

The announcement came in Parliament on 6 October.

The Public Service Division (PSD) had reviewed property transactions by 191 public officers who worked in agencies involved in rail planning and who bought properties between 2007 and 2014 near locations that were later announced as MRT stations, AsiaOne reported. For each, the PSD looked at the officer's role at the time, whether they had access to relevant non-public information, and the timing and circumstances of the purchase.

Eight of those officers have now been referred to the police. Further checks are still going on.

Mr Chan was careful about what that means. "A referral does not mean that wrongdoing has been established. The police will look into the facts independently, and due process will be followed," he said. As of the announcement, he said, the Government had "not concluded whether any wrongdoing or especially any criminal offences have been committed", according to Mothership.

The police said they could not comment further at this stage.

The review traces back to a working paper published on 11 September by the US-based National Bureau of Economic Research. It has not been peer reviewed. Al Jazeera reported that its authors are economists from Stanford University, Columbia University and the University of Hong Kong.

The researchers took private-property transaction records from 1995 to 2019, which carry buyers' names from caveat filings, and linked them to six editions of the government's public staff directory, the Singapore Government Directory Interactive, The Straits Times reported. That let them track which buyers were civil servants.

They then looked at purchases near MRT stations that had been planned but not yet publicly announced. Civil servants bought homes near such stations at higher rates than a matched group of non-civil servants, and the difference was concentrated in the one to two years before announcements. Al Jazeera reported that the paper put civil servants at 60 per cent more likely to buy in these areas.

One more finding matters: the pattern largely disappeared after 2011. The PSD's review initially covered purchases from 2007 to 2011, and was later extended to 2014 "as a matter of prudence", AsiaOne reported.

From the start, the PSD drew a line between a pattern and a case.

In a statement on 25 September, it said the paper's statistical patterns were "a concern" and that it took them seriously. But it said such patterns do not, by themselves, show whether any individual officer actually had access to non-public information about station locations, or whether that information influenced a purchase.

It gave an example. Information or speculation about planned MRT lines and stations can already be in the public domain, or be used to market new developments. "An officer may have purchased a unit in such a development for reasons unrelated to any non-public information," the PSD said. Each transaction, it added, "must be examined carefully before any conclusion is drawn."

It also set out the safeguards. Public officers must declare their property purchases. Access to sensitive information is controlled on a need-to-know basis. Officers who hold non-public information relevant to a personal transaction, whether in property, vehicles or financial instruments, must declare it and get approval before going ahead, and Mothership reported that those requirements extend to officers' spouses and financially dependent children. The PSD said these rules have been strengthened over time.

It is tempting to assume that any home near an MRT station is a winning investment. Our resale data says otherwise.

We looked at private homes that were bought and later resold, and compared those near a station with the market as a whole:

Gross gains on resold private homes, before costs. Distance is straight-line to the nearest station. The near-MRT rows cover condos only; the baseline includes landed homes.

Owners near a station did about as well as everyone else. Not better.

That is not because stations add no value. It is because buyers already know they do, so the value tends to show up in the price you pay. By the time a station is on a public map, sellers nearby ask for more, and buyers pay it. What you pay for a home near an MRT station already includes the station.

Which is exactly why the paper's question is about timing. The one buyer who can get ahead of that price is the one who knows where a station will go before everyone else does. That is what the review is checking, and it is why a statistical pattern in the years before announcements drew so much attention.

For an ordinary buyer, the lesson is not to avoid MRT stations. It is to be realistic about what you are paying for.

Once a station is announced, it is public information. Developers and agents use it to market projects, and buyers factor it in. The PSD made this point itself. If you buy near an announced station, expect to pay for the convenience.

Buy it for the life, not the bet. A short walk to a train is worth a great deal to many families: a shorter commute, independence for children, easier visits for older parents. Those are good reasons to pay more. Expecting the station to also deliver above-market profits is a different claim, and our data does not support it on average.

Check the timing of the line. Stations take years to open, and projects can be delayed. Your daily commute only improves once the station is running.

Our longer analysis, Does buying near an MRT make a property more profitable?, breaks the numbers down further.

This is general commentary, not advice on any purchase.

Three things happen from here.

The police investigate the eight referrals. They will look at the facts independently, Mr Chan said, and due process will be followed. Until they finish, no officer has been found to have done anything wrong.

The PSD's checks continue. The 191 officers reviewed so far are not necessarily the end of it; further checks are ongoing.

The Government has set out its position. "Where wrongdoing is established, we will act firmly," Mr Chan said, as reported by Mothership. Public officers, the Government said, "must never use information obtained through their official duties to advance their own private interests," as Al Jazeera reported.

There is also a wider question, which this review cannot settle: how much the safeguards strengthened over time account for the pattern fading after 2011. The paper's finding that it largely disappeared suggests something changed. What exactly, the reporting does not say.

It would be easy to see this as a story about eight people. It is bigger than that.

In Singapore, the Government plans where homes, trains and jobs will go years in advance. That long-term planning is one of the system's strengths. But it means a small number of people know things that would be very valuable to a property buyer, long before anyone else.

The system works only if the public trusts that those people do not use what they know. That is why the PSD's rules require declarations and approvals, and why a statistical pattern in an academic paper led to a review of nearly 200 officers' purchases.

It is also why the PSD has been so careful about the difference between a pattern and proof. Both matter. A pattern earns scrutiny. Only evidence about a specific purchase can establish that someone did wrong.

Some limits, stated plainly.

Our numbers are not timed to announcements. We compare resale gains near stations with the wider market, but we do not split purchases by whether they came before or after a station was announced. That is exactly the comparison the paper made, and we have not tried to repeat it.

The comparison is not perfectly like-for-like. Our near-MRT rows cover condos only, because landed homes are not in our station-distance lookup. The baseline includes landed homes. Read the gap, which is close to zero, as directional, not precise.

Distance is straight-line, to the nearest station, not walking distance.

Gross gains, before costs. Stamp duties, agent fees and financing costs are not deducted.

A referral is not a finding. We report the review's numbers as the Government gave them. None of the eight officers has been found to have done anything wrong, and the paper has not been peer reviewed.

What we would not hedge on: once a station is public, its value tends to be in the price. That is why advance knowledge would be valuable, and why the rules against using it matter.

Two kinds of numbers, kept apart.

From the reporting: the 191 officers reviewed, the 2007 to 2014 window and its extension, the eight referrals, Mr Chan's and the PSD's statements, and the safeguards come from CNA, AsiaOne and Mothership. The paper's publication date, data, method and findings come from The Straits Times, and its authors' universities and the "60 per cent more likely" figure from Al Jazeera. All are linked below.

No officer has been found to have committed any wrongdoing. It is opinion and general information, not legal, financial or property advice.
