The Thai Excise Department has proposed a THB 6 billion (US$ 177 million) vehicle replacement scheme offering a subsidy of THB 40,000 per vehicle to encourage motorists to replace ageing vehicles with new, locally manufactured pickups.

The nationwide programme aims to reduce PM2.5 pollution from older engines and support Thailand's domestic pickup market, where tighter lending conditions have affected sales.

A Finance Ministry source stated that the department had requested THB 6 billion from the government's borrowing programme under the 2026 Emergency Decree, which authorises the Ministry of Finance to borrow funds to address the energy crisis and support the country's energy transition.

The scheme would be implemented in fiscal year 2027 through a co-payment arrangement involving manufacturers, dealers and financial institutions. Eligible buyers would receive THB 40,000 towards a new pickup or pickup-based passenger vehicle, either as a deposit contribution or an immediate reduction in the purchase price. The support is intended to lower monthly instalments and borrowing requirements while reducing lenders' exposure to vehicle-financing risks.

Ageing vehicles and pollution drive the proposal

According to 2026 Department of Land Transport figures cited in the proposal, Thailand has passenger cars, pickups and vans that are at least 10 years old, including vehicles aged between 20 and 30 years and those in use for more than 30 years. Older diesel pickups complying only with Euro 1, Euro 2 or Euro 3 emissions standards are identified as sources of nitrogen oxides (NOx) and fine particulate matter.

The proposal cites Pollution Control Department estimates indicating that vehicle-related emissions account for nearly 60% of urban PM2.5 pollution in some assessments. Research by Chulalongkorn University estimated the economic damage caused by PM2.5 pollution to Thai households at THB 2.17 trillion in 2019, rising to THB 4.62 trillion when other air pollutants were included. The proposal also cites medical costs and economic losses associated with premature deaths in Bangkok amounting to THB 3.78 billion, equivalent to approximately 0.065% of the capital's gross provincial product.

Lending conditions and pickup sales

The proposal also aims to support Thailand's pickup industry, which forms part of the country's automotive manufacturing sector. The domestic market has weakened as financial institutions have tightened hire-purchase lending requirements amid concerns over household debt and borrowers' repayment capacity.

The department referred to the Bank of Thailand's second-quarter 2026 assessment, which identified tighter lending conditions and a continued contraction in vehicle hire-purchase loans since the first quarter of 2024. The proposal linked these restrictions to the concentration of Stage 2 loans, involving borrowers with significantly increased credit risk, and non-performing loans (NPLs) in the vehicle financing segment.

Lessons from earlier vehicle subsidy schemes

The Excise Department has incorporated safeguards based on earlier automotive stimulus programmes, including Thailand's first-car buyer scheme. The proposal notes that poorly designed incentives can create artificial demand, encourage excessive borrowing and contribute to bad debt.

Thailand's limited end-of-life vehicle dismantling capacity is another constraint. According to the department, certified dismantling facilities have limited annual processing capacity. Extending the subsidy to all new vehicle categories could create processing bottlenecks; therefore, the proposal restricts eligible purchases to pickups and pickup-based passenger vehicles.

Eligibility for the THB 40,000 subsidy

Participation would be restricted to Thai nationals aged 20 or above who own an eligible vehicle registered in their name. Each participant could exchange one old vehicle and receive a subsidy towards one new vehicle.

The surrendered vehicle must have been registered before 2012 and fall into one of three categories:

- Private passenger cars carrying no more than seven people.
- Private passenger vehicles carrying more than seven people.
- Privately registered goods vehicles.

The vehicle must have identifiable engine and chassis numbers, with its current annual vehicle tax fully paid. It must also have no outstanding finance agreements with financial institutions and must not be subject to seizure or attachment.

Requirements for new vehicles

Only domestically manufactured pickups and pickup-based passenger vehicles (PPVs) would qualify for the subsidy. Eligible vehicles must comply with Euro 5 or Euro 6 emissions standards, have carbon dioxide emissions of no more than 185 grammes per kilometre and support B20 biodiesel or use electrified-vehicle (xEV) technology. Participating manufacturers must operate pickup production facilities in Thailand and be registered excise taxpayers.

Trade-in and scrappage process

Dealers would notify the Department of Land Transport that the old vehicle had been withdrawn from use and arrange for its chassis identification number to be cancelled. The vehicle would then be transferred to a Ministry of Industry-certified dismantling facility, which would issue an official destruction certificate.

Manufacturers would submit sales documents, confirmation of chassis-number cancellation and registration documents for the new vehicle through an information system. The Government Savings Bank would act as the payment agent, transferring the subsidy to participating manufacturers for onward distribution through dealers. Buyers would receive it as a deposit contribution or an immediate reduction in the purchase price.

Additional discounts and low-interest loans

Under the co-payment arrangement, participating manufacturers would be expected to offer additional discounts alongside the government's THB 40,000 contribution towards lower-emission vehicles. Buyers opting for eligible xEV pickups could also apply for financing under the Government Savings Bank's GSB Thai Business Revival soft-loan programme, with interest capped at 5% per annum.

The subsidy, manufacturer discounts and financing arrangements are intended to reduce borrowing requirements, ease repayment obligations and limit the risk of future NPLs.

THB 6 billion spending timetable

The Excise Department has proposed a disbursement schedule beginning in January 2027, with initial expenditure projected at THB 136 million. The allocation for August 2027 is THB 751 million, while a further THB 2.014 billion is listed under September for anticipated payments covering September to December 2027.

The projected payments are:

- September: THB 760 million
- October: THB 658 million
- November: THB 521 million
- December: THB 75 million

Environmental and economic targets

The scheme aims to reduce annual greenhouse gas emissions by at least 310,000 tons of carbon dioxide, while PM2.5 and nitrogen oxide emissions from replaced vehicles are expected to decrease by at least 30%. The department also projects that sales of domestically manufactured pickups under the programme will generate economic activity worth at least THB 82.5 billion.

Monthly monitoring and performance reviews

The Excise Department would report implementation progress to the Finance Ministry and the committee overseeing expenditure under the government's borrowing programme at the end of each month. If actual disbursements fall more than 15% below the planned level, the department would investigate the reasons for the shortfall.

A mid-programme evaluation would be conducted in the eighth month, followed by a final assessment in the 15th month.
