Ten per cent, until the thirtieth

Bangkok’s minimum wage is ฿400 a day, set by the Wage Committee’s announcement (No. 14) of 17 June 2025 and still the operative instrument.

BTS’s own fare page gives ฿17 to ฿47 for a single journey on the concession section. Since 1 November 2025 the extensions charge by distance too, ฿17 to ฿45, and a journey that crosses from one to the other is capped at ฿65. A return commute at that cap is ฿130 — thirty-two and a half per cent of a day’s minimum wage. Over a twenty-two day month, ฿2,860. Which is still thirty-two and a half per cent, because the ratio does not move with the number of days.

Roughly a third of your gross pay, to arrive at the place you earn it.

Since 1 December 2025, a Thai commuter on the Purple or Red line has been able to pay ฿40 for the whole day — a daily pass, bought with a contactless bank card, on a Cabinet decision of 25 November 2025. A day on those two lines is ten per cent of a Bangkok day’s wage. That runs to 30 November 2026.

From 1 June to 30 September 2026, on nearly every line, an eligible Thai adult who registered for ไทยช่วยไทย พลัส paid 40% of the fare and the state paid 60% — capped at ฿200 a day and ฿1,000 a month, single-journey tickets only. That subsidy is over.

What the ฿20 fare was, and what it was not

This article said, in the version published on 8 September, that a ฿20 flat fare had been charged on every line since 1 October 2025. It had not. What follows is the record, because the confusion is general and not only mine.

The ฿20 flat fare was real on two lines. It began on the Red and Purple lines on 16 October 2023, and the Cabinet extended it on 29 November 2024 to run to 30 November 2025.

The ฿20 fare on every line was announced, and never charged. In June 2025 the government set out the scheme: all eight lines, thirteen routes, Thai nationals only, registered by thirteen-digit ID through the ทางรัฐ app, from 30 September 2025. A Cabinet resolution of 8 July 2025 authorised it for a year from 1 October 2025 and pulled the two-line fare’s end date forward to 30 September to match. Then the government changed. Within days of taking office in September 2025 the new administration said the all-lines scheme might not continue on grounds of cost, and Thai PBS’s policy tracker records it as closed from 1 October 2025. The registrations were taken; the fare never was.

What the Cabinet did instead, on 30 September 2025 — the day the two-line fare was due to lapse — was extend it by two months, to 30 November 2025, “to reduce the burden of expenditure on the public”, with an instruction to the Ministry of Transport to return within those two months with something sustainable. On 25 November 2025 it did: the ฿40 day pass on the same two lines, from 1 December 2025 to 30 November 2026. Not ฿20 a trip; ฿40 a day, for as many trips as you make.

So the sequence is: a two-line ฿20 fare for two years; an all-lines ฿20 fare that existed as a resolution and a registration form; a two-line ฿40 day pass; and, laid over everything for four months, a 60/40 subsidy. Anyone who tells you Bangkok has had a ฿20 fare on every line is describing the resolution, not the turnstile. I did.

Three end dates, and the space between them

Put the announced calendar on one line, because nobody has.

• 30 September 2026 — the ไทยช่วยไทย พลัส 60/40 subsidy ended. It began on 1 June 2026 and was always a four-month measure.
• 30 November 2026 — the ฿40 day pass on the Purple and Red lines ends.
• 1 January 2027 — the joint fare under the Common Ticket Act begins: ฿17 to enter, once, and ฿45 maximum for a journey however many lines it crosses, approved by Cabinet on 23 June 2026.

So October and November have no announced continuation for anyone outside the Purple and Red lines, and December has nothing announced in it for anyone at all.

That is not this article inferring a gap from silence. The Deputy Minister of Transport, after the Common Ticket Policy Committee met on 14 August 2026, set out the timetable himself: the outstanding subordinate legislation finished by late November, system testing in December, live on 1 January 2027. The replacement has a start date and each current measure has an end date, and none of them meet.

Nobody planning a commute can currently price December.

Except that this has happened before, and the Cabinet moved

The gap is what the announced calendar says. It is not what history says, and the article would be misleading if it stopped at the calendar.

Every end date in this policy family has moved, and one moved on the day. The two-line ฿20 fare was set to run to 30 November 2025 by a resolution of 29 November 2024; a resolution of 8 July 2025 pulled that forward to 30 September; the resolution of 30 September 2025 put it back. The day pass that followed was decided five days before the fare it replaced expired.

So the honest position is not that a late extension is coming. The announced calendar left a gap after 30 September, and the 16 October check found no continuation to fill it. This policy’s end dates have moved late and repeatedly, including once on the expiry day itself, but precedent is not a fare notice.

What that precedent also carries is the instruction attached to it. The Prime Minister directed the Ministry of Transport to find a sustainable method of reducing the burden on the public without loading it onto the state. The ฿17–45 joint fare announced for January is, on the face of it, the answer to that instruction — which is a reason to expect the gaps to be bridged rather than left, and no reason at all to be able to price them in advance.

The benchmark, and the number that is now published

The Thailand Consumers Council has campaigned on exactly this arithmetic, and it has put its threshold in baht.

Its position is that daily travel should not exceed 10% of the minimum wage — or about ฿40 a day.

The ฿40 day pass on the Purple and Red lines costs exactly ฿40.

Both figures are published. Neither this article nor any document it found establishes that one produced the other, and the article is not going to claim it did. What can be said is that the campaigning body’s stated affordability figure and the price of a day on two of the lines are the same number, and that for a commuter on those lines the ratio went from roughly triple the benchmark to sitting on it.

The council’s comparative figures, as reported: London’s metro fare at around 5% of the minimum wage, Tokyo at around 9%, German commuters at roughly ฿330 a month. ⚠️ Those are the council’s figures, not independently verified here, and they were calculated when the Thai minimum wage was ฿353 — so they are not directly comparable with the arithmetic above, which uses ฿400.

And ฿400 is the friendliest denominator available. The same announcement sets ฿372 a day in Nonthaburi, Pathum Thani, Samut Prakan, Nakhon Pathom and Samut Sakhon — which is where the network’s outer stations are. The Purple line ends in Nonthaburi, the Green line runs into Samut Prakan, the Pink line crosses both.

So the commuter with the longest journey is also, by law, on the lower wage. At ฿372, the ฿40 day is 10.8 per cent — over the threshold rather than on it. The arithmetic that lands on the mark lands there only for somebody who both lives and works inside Bangkok — and only on two of the lines.

On every other line the subsidy does the work for now. Forty per cent of a ฿65 BTS journey is ฿26; a return is ฿52, thirteen per cent of a ฿400 day — until 30 September, and only for a Thai adult who registered.

What ฿17 to ฿45 actually does to that

Now run the same arithmetic on the replacement.

฿45 a trip is the announced ceiling. A return commute at the ceiling is ฿90 — twenty-two and a half per cent of a ฿400 day, and 24.2% of a ฿372 one.

฿17 is the announced floor. A return at the floor is ฿34 — eight and a half per cent.

So the new structure spans from comfortably under the council’s threshold to more than double it, depending how far you go. The day pass does not do that. ฿40 is ฿40 however far you ride the Purple or Red line; ฿45 is what the longest journeys will cost, each way.

The mechanism is worth knowing because it is unusual: the full fare is deducted first, and anything above ฿45 is refunded to the passenger afterwards. You are charged the concession fare and then given the difference back.

And the eligibility narrows each time. The all-lines ฿20 scheme that never ran was for holders of a Thai thirteen-digit national ID — foreign tourists were expressly excluded. The 60/40 subsidy is for Thai nationals aged eighteen and over who registered. The joint fare is announced for EMV cardholders who are Thai. The ฿40 day pass asks only for a contactless bank card. ⚠️ No source this article found states whether a foreign resident holding a thirteen-digit number qualifies for the subsidy or the joint fare. That is the question most readers of this publication will have, and the honest answer is that it has not been published.

And you still cannot do it with one card

A detail that says more about the system than the fares do.

The ฿40 day pass needs an EMV contactless bank card. The 60/40 subsidy needs the เป๋าตัง app and a ticket office. The all-lines scheme that never ran would have taken an EMV card or an account-based stored-value card such as Rabbit ABT. Neither card works everywhere. Rabbit covers Green, Gold, Yellow and Pink. EMV covers Red, Blue, Purple, Pink, Yellow and the Airport Rail Link — not Gold, and not Green.

There is no single card that works on all thirteen lines. The fares keep being made uniform by decree; the medium never is.

And crossing between networks, you must enter and leave only at designated interchange stations. Do anything else and you pay the ordinary fare.

The Green and Gold lines still need EMV readers fitted, which is entangled with the unfinished transfer of both lines from the BMA to the MRTA. On 14 August the position was that if the transfer is not done, the BMA installs them; if it completes within a month or two, the MRTA does.

The structural fix was legislated, and then redesigned

Here the article has to correct itself.

An earlier version said the structural fix was “the common ticketing legislation” and treated it as pending. It is not pending. It is law.

The Common Ticket System Management Act B.E. 2568 (2025) was published in the Royal Gazette on 27 December 2025 and came into force the following day, alongside the Rail Transport Act. It provides for a single payment method across rail, bus, boat and other systems; it forbids the repeated boarding charge when changing systems; it creates a Common Ticket System Promotion Fund to compensate operators when boarding charges are cut, funded from the budget, from concessionaire contributions and from its own returns; it puts a consumer representative on the policy committee; and section 54 requires the state agencies that are parties to concession contracts to renegotiate them to match the joint fare, within one year of the relevant ministerial regulation taking effect.

Which is the fix. And it is behind.

Twenty pieces of subordinate legislation were to be issued within 180 days — approximately June 2026. As at the committee meeting of 14 August 2026, ten of sixteen had been approved. Ministry announcements were expected in September 2026, ministerial regulations — which need Cabinet — in October 2026. The deadline passed and the instruments did not.

What it cost to not fix it properly

And then the decision this article was built to notice, which is now on the record with prices attached.

In April 2026 the announced design was different. A ฿40 all-day cap on a time basis: ฿40 for a journey of up to forty minutes, ฿20 more beyond that, ฿60 maximum for the day, short trips paying the actual fare, rising ฿5 a year to shrink the subsidy. It required buying the concessions back and converting them from PPP Net Cost — where the private party takes the fare revenue — to PPP Gross Cost, where the state takes the revenue risk and pays an operator to run the trains. The assets and operating contracts were valued at over ฿140 billion.

By August the design was ฿17–45 a trip with compensation, and no buyback.

The minister set out the reasoning himself. Compensation is estimated at about ฿4 billion a year. Buying back the whole system he put at around ฿200 billion, on which interest at about 2% is roughly ฿4 billion a year — about the same. So the state will pay the compensation through the transition and revisit the question when the concessions expire.

Read that as the answer to why a fare is ฿65 in the first place.

Article 164 Nobody built the connections found that Bangkok’s road network dead-ends across 45% of its length because the state built the arterials, private landowners built the capillaries, and nobody had a reason to connect them. Access is a private good; connection is a public good; and nobody supplies a public good.

The rail network is the same failure in a different century. Each concession was a rational private undertaking. Fare integration across concessions benefits every passenger and no individual operator, so nobody built it — and when the state finally costed buying the boundary out, it found the price roughly equal to paying around it forever, and chose to keep paying.

That is not a criticism of the choice. On the numbers as given it is defensible. It is a description of what the subsidy is. It does not integrate the fares. It pays, every journey, for the fact that they are not integrated — and the state’s own framing is that this continues until the concessions run out. The first Green line concession ends in 2029.

The honest caveats

Four, and they cut in different directions.

Minimum wage is one denominator among several. Median wage would produce a lower percentage and a less alarming figure. Minimum wage is the right denominator for asking whether the poorest commuter can afford the system; it is not the same as asking what the average commuter pays.

Most journeys are not the maximum fare. ฿65 is the BTS ceiling and ฿45 will be the joint ceiling, not the typical trip. The high percentages describe a long commute — which is precisely the commute a low-income worker priced out of the centre is most likely to have.

The government’s own accounting said the all-lines fare would pay for itself. The Ministry of Transport estimated the benefits of the ฿20 all-lines measure in FY2026 at ฿21,812 million across economic, social and environmental effects, against a ฿5,668 million budget. ⚠️ That was the ministry’s estimate for a scheme that was then not run, and this article has not examined the method.

And the wages side has moved least. The minimum wage rose about ฿100 over ten years, and announcement No. 14 was still the operative instrument as at late August 2026 with no successor. A fare-to-wage ratio has two numbers in it, and only one of them has been the subject of a policy.

Common misconceptions

“Thai fares are high in absolute terms.” They are high relative to wages, which is the comparison that determines whether people can use the system.

“Bangkok has a ฿20 fare on every line.” It was announced for 30 September 2025 and never charged. The ฿20 fare ran on the Red and Purple lines only, from October 2023 to November 2025, and became a ฿40 day pass on those lines from 1 December 2025.

“Something takes over on 1 October.” Nothing announced does — the 60/40 subsidy ends on 30 September, the ฿40 day pass runs to 30 November, and the joint fare starts 1 January 2027. But the Cabinet extended this policy’s predecessor on its expiry day in 2025, so an announcement late in a month would follow precedent rather than break it.

“The replacement is also ฿20.” It is ฿17 to enter and ฿45 maximum a journey. A long return commute goes from ฿40 a day on the two-line pass to ฿90.

“Anyone can use it.” The subsidy and the joint fare are announced for Thai nationals; the all-lines ฿20 scheme that never ran excluded foreign tourists expressly. The ฿40 day pass asks only for a contactless bank card.

“One card works everywhere.” No card covers all thirteen lines. Rabbit covers four; EMV covers six.

“Integration is still a proposal.” It is an Act, in force since 28 December 2025. What is late is the twenty subordinate instruments, due around June 2026.

“The fare reflects distance.” It substantially reflects how many separately-concessioned systems the journey crosses.
