The lawful range

ทุนเทา. Grey capital. Money that is not obviously criminal and not obviously clean, arriving through entirely legitimate corporate forms.

In Thai usage the term points predominantly at Chinese capital, and it is worth being straightforward about that rather than coy. The enforcement record supports the association: the districts the regulator has scanned, the sectors it has prioritised, and an operation on Ko Samui in which arrest warrants were issued for 62 foreign nationals alongside the dismantling of 60 companies and the seizure of land reported at around a billion baht.

What I could not find is an official breakdown by nationality of the entities actually flagged, and this article is not going to invent one. The association is real and reported. The composition is not published.

And here is why that matters less than it looks: the argument below does not depend on whose money it is.

What the law actually restricts

The Foreign Business Act B.E. 2542 (1999) governs this. In broad terms it reserves categories of business for Thai nationals and requires a foreigner wanting to operate in them to hold a licence — and it determines who counts as a foreigner by shareholding.

Which produces the familiar structure: 51% Thai, 49% foreign. Below the line, the company is Thai and may trade freely. Above it, permission is required.

A nominee arrangement is one where the Thai 51% is held by someone who does not really own it — a person lending their name, holding shares they did not pay for, on behalf of the foreign party who supplied the money and takes the profit. Section 36 of the Act prohibits this and the penalty is up to three years’ imprisonment and a fine of up to ฿1 million.

That is the offence. Now look at how the state goes about finding it.

The screening criterion is compliance

The Department of Business Development has been running a large detection programme. As at 23 June 2026 it defined the population of nominee-risk entities for targeted examination as those with foreign shareholding between 0.01% and 49.99%.

Read that range again.

0.01% to 49.99% is the entire span of foreign ownership that the Foreign Business Act permits without a licence. It is not an aggressive interpretation, a grey zone, or a loophole. It is the lawful range.

Which means the risk indicator is: having done what the law allows.

This is not a criticism of the department, and I want to be exact about that. They are not being lazy. They are being logical, because there is genuinely nothing else in the register to look at.

Why there is nothing else to look at

Here is the structural problem, and it is the reason this campaign requires 46,918 examinations rather than a database query.

The Act’s test is a percentage. A percentage is a document. It is written on a share register, filed at registration, and available to anyone.

The thing the Act is trying to prevent is control. And control is not a document. It is a relationship, and it lives in places the share register does not reach — who actually paid for the shares, who can remove the directors, who holds the lease, who supplies the goods, who owns the brand, who is owed money by the company and on what terms.

So a company with 49% foreign ownership and a Thai majority is, on the register, indistinguishable from a company with 49% foreign ownership and a Thai majority. One is an ordinary joint venture with genuine Thai partners. The other is a shell. The filed document is identical.

This site has been here before, twice, in very different rooms. Article 145 The ballot proves nothing found a Senate selection whose ballots contained nothing that could distinguish collusion from association, so the truth had to be assembled from eighty thousand pages of testimony. Article 142 Somebody has to be in the chair found the benign version — a market that works precisely because performance happens in public.

A rule binds when the behaviour it governs is observable. The Foreign Business Act governs control and observes shareholding, and those are not the same thing.

What the department did about it, which is the right answer

The response has been to stop relying on the register, and it is worth setting out because it is a sensible piece of institutional learning.

Order 2/2026 extended examination to changes in shareholder and director structure made after registration. That closes an obvious gap: a company can be registered clean and restructured the following month, and a snapshot at incorporation proves nothing about the state of the thing a year later.

From 1 August 2026 the programme moved to scanning money trails alongside shareholding structures. Following the payments rather than reading the filings.

That is the correct move and it is also an admission. If the register could answer the question, nobody would need to trace the money. The department has effectively conceded that its statutory test is not diagnostic and gone looking for evidence outside it.

The number that shows this is an industry

One figure from the scanning programme is worth more than all the raid totals put together.

The department found 140 accountants connected to 2,040 companies.

That is roughly fifteen companies each, and it tells you something the enforcement statistics do not. This is not a large number of individual arrangements made privately between a foreign investor and a Thai acquaintance. It is a service, supplied at volume, by professionals, as a product.

Which is consistent with the sectors the department has prioritised. Alongside villas, construction and brokerage sit accounting firms and law firms — the enablers appear on the target list as businesses in their own right, not merely as advisers to the businesses being examined.

And it explains the scale. Over a year the department examined 46,918 entities across six high-risk groups, having watched around 26,000 across four risk categories the previous year. 6,551 were identified as potentially operating in breach of the Act. Enforcement has run across 35 areas in 11 provinces, with 53 entities flagged in a single Bangkok district scan and separate operations on Ko Samui and Ko Pha-ngan and in Lak Si, where the department reported abnormal money movements.

Flagged is not convicted, and the whole argument of this article is that the flag cannot tell the difference.

Who actually gets caught

Now the part that this site keeps finding, in market after market, and which I am going to stop describing as a coincidence.

Section 36 of the Foreign Business Act is the provision, and it is worth reading rather than summarising.

It reaches a Thai national, or a juristic person that is not a foreigner under the Act, who assists, supports or joins in a foreigner’s business in a scheduled category the foreigner is not licensed for; or who carries on a foreigner’s business holding it out as their own alone; or who holds shares on a foreigner’s behalf in a partnership, a limited company or any juristic person, so as to let the foreigner operate in evasion of the Act.

The penalty is up to three years’ imprisonment, or a fine of ฿100,000 to ฿1,000,000, or both — and the court shall order the assistance, the joint operation or the shareholding to end, with a further fine of ฿10,000 to ฿50,000 a day for as long as the order is defied.

Notice the floor. Coverage of this offence, including this article’s earlier draft, reports it as “up to ฿1 million”. The fine starts at ฿100,000. For somebody paid a few thousand baht to put their name on a share register, the minimum is the number that matters.

And notice who else the section catches, because an earlier version of this article had this wrong. Section 36 applies “together with the foreigner who consents to the Thai national or non-foreign juristic person doing so” — on the same penalty. The statute is not addressed to the visible party alone.

So the asymmetry this article is about is not in the drafting. It is in the finding.

The Thai nominee is the findable party. Their name is on the register. They live here. They can be served, arrested and tried. The foreigner who consented is equally liable under the same section and is frequently in another country, behind a structure the register does not describe.

A law that reaches both and locates one produces the same outcome as a law that reached only one — which is a sharper claim than the one this article made before, and it is the statute’s own text that sharpens it.

The foreign principal supplied the capital, takes the profit, may hold no Thai document at all, and may not be in the country. The Samui operation issued warrants for 62 foreign nationals, which shows it can be done. It also shows what it costs to do it, and how much of the enforcement effort is consumed by reaching the person who is not standing there.

Meanwhile the person who lent their name is frequently receiving a small monthly fee for a company they know nothing about, carrying a director’s or shareholder’s exposure they were probably never told about in terms they understood.

This is the fourth article in a row to land on the same shape. Article 143 The venue kept the commission found a venue keeping a commission on a worker it did not employ, with liability stopping at the worker. Article 144 The channel is the collateral found an affiliate criminally exposed for claims about a product they had no means of examining. Article 146 The person holding the bag found a carrier answerable for the contents of a bag they did not pack. Article 149 Nobody is going to sue you found illegal lenders collecting on borrowers’ social exposure because they had no legal remedy at all.

In every case liability attached to the visible party, and the visible party had the least information and the least money.

Four instances across four unrelated markets is no longer a recurring observation. It should go into the root document as a candidate structural finding beside the legibility argument, and I would put it this way: in Thai systems, obligation attaches to whoever can be found, and the design of most systems ensures that is not whoever benefited.

The honest counter-argument

Three things should be said for the other side, because the article would be unfair without them.

First, foreign ownership limits are not a Thai eccentricity. Most countries restrict foreign control of some sectors, and most use shareholding as at least part of the test, for the good reason that any alternative requires a regulator to adjudicate what “control” means case by case. That is expensive and it is arbitrary, and a bright line has real advantages.

Second, the problem the state is addressing is genuine. Capital of unclear origin entering a country through corporate shells, buying land and tourist businesses, is not a nativist fantasy. The seizure of a reported billion baht of land in one operation is not nothing, and the department’s concern that entire local sectors can be acquired through structures that are invisible on paper is a reasonable one.

Third, the department is adapting. Extending scrutiny past registration and tracing money rather than reading filings is exactly what the analysis in this article implies it should do. That deserves credit rather than the reflexive assumption that enforcement is theatre.

The criticism that survives all three is narrower. A test that flags every compliant company as a risk cannot be run at scale without either enormous cost or arbitrary selection, and the cost has landed as 46,918 examinations to find a subset of 6,551 that still has to be investigated one at a time.

And the exposure created in the meantime falls hardest on people holding a name-lending arrangement they were paid very little to enter.

---

Practically

For foreign investors operating legitimately. Nothing here suggests ordinary joint ventures are unlawful. But you should expect to be inside the screened population, because the screened population is everyone under 50%. Documentation of who paid for the Thai shareholding, from where, and what the Thai shareholders actually do, is the difference between an examination and a problem.

For anyone being offered money to hold shares or act as a director in a company they will not run: the offence carries up to three years and a fine that starts at ฿100,000 and runs to ฿1 million, plus a court order to unwind the holding and ฿10,000 to ฿50,000 a day if that order is not obeyed. The person offering will not be standing next to you, and the fee will not cover a lawyer.

For Thai professionals, note that accounting and law firms are on the department’s own priority list as businesses to be examined, not merely as advisers.

None of this is legal advice.

Common misconceptions

“Nominee arrangements are a grey area.” Section 36 of the Foreign Business Act prohibits them expressly, with up to three years’ imprisonment and a fine of ฿100,000 to ฿1 million — a floor as well as a ceiling — and a daily fine on top if a court’s unwinding order is defied. It applies to the Thai nominee and to the foreigner who consented, on the same terms.

“49% foreign ownership is suspicious.” It is the legal maximum without a licence. The department’s own risk definition covers 0.01% to 49.99%, which is the entire lawful range — being in it is not evidence of anything.

“6,551 companies have been caught.” They have been flagged for examination. The point of this article is that the flag cannot distinguish a joint venture from a shell.

“The register shows who owns a company.” It shows who holds the shares. Who paid for them, and who controls the company, are different questions.

“This is a small number of private arrangements.” 140 accountants were found connected to 2,040 companies. It is a service industry.
