Southeast Asia energy transition — why the region is both a clean energy growth story and a fossil fuel holdout
Southeast Asia is home to 680 million people across 11 countries, spans some of the world's fastest-growing economies, and is simultaneously one of the most complex energy markets on earth. Solar capacity is growing faster than almost anywhere. EV manufacturing is taking root. And governments are still spending tens of billions of dollars annually to keep petrol and diesel below market cost.
The regional price landscape
The range of petrol prices across Southeast Asia rivals Latin America in its width. Singapore — a major oil refining hub — charges among the highest pump prices in Asia due to its road usage pricing, high excise duties, and lack of any subsidy. Indonesia, Malaysia, and Brunei cluster at the bottom with subsidised or managed prices. The table below gives a mid-2024 snapshot:
| Country | Petrol price (USD/litre, approx.) | Regime |
|---|---|---|
| Brunei | ~0.33 | State-subsidised, fixed |
| Malaysia | ~0.46 | Subsidised (RON 95 capped) |
| Indonesia | ~0.65 | Subsidised (Pertalite/Solar) |
| Vietnam | ~0.91 | Managed (stabilisation fund) |
| Thailand | ~1.12 | Market-linked, Oil Fund smoothing |
| Philippines | ~1.20 | Largely market |
| Singapore | ~2.20 | Market + high excise |

Indonesia: the subsidy giant
Indonesia is the region's largest economy and its largest fuel subsidy spender. State oil company Pertamina sells Pertalite (RON 90 petrol) and Solar (diesel) at government-set prices below market cost, with the government compensating Pertamina through the national budget. When Brent crude spiked above USD 100/bbl in 2022, the subsidy bill exceeded USD 30 billion — roughly 10 % of the government's total expenditure.
In September 2022, facing unsustainable fiscal pressure, President Joko Widodo raised Pertalite prices 30 % and Solar prices 32 %. The price increases triggered street protests in Jakarta and other cities. The episode echoed the 1998 subsidy removal that contributed to the fall of Suharto — fuel subsidy politics in Indonesia are freighted with historical significance. The IMF's Indonesia Article IV and the World Bank Indonesia brief both cover the subsidy fiscal dimension.
Malaysia's approach has been similar: RON 95 petrol is capped at MYR 2.05/litre regardless of market conditions, with PETRONAS and the government absorbing the difference. Malaysia announced a targeted subsidy reform in mid-2024, restricting the RON 95 subsidy to Malaysian citizens and excluding high-income groups — a model our Asia subsidies reform article examines in detail.
Thailand, Vietnam, Philippines
Thailand operates an Oil Fund (กองทุนน้ำมันเชื้อเพลิง), a levy-and-subsidy mechanism managed by the Energy Policy and Planning Office (EPPO). When wholesale prices fall below a reference level, the fund collects a levy; when prices spike, it pays a subsidy. The fund ran deeply negative during the 2022 price spike, accumulating debt of over THB 100 billion — an experience that has prompted reform discussion. Retail prices in Thailand broadly track international benchmarks within the smoothing band.
Vietnam uses a similar stabilisation fund (Quỹ Bình ổn giá xăng dầu) and revises pump prices every 10 business days based on a formula tracking international product prices, converted at the official USD/VND rate. The Ministry of Industry and Trade (MoIT) oversees pricing. Vietnam's price transparency is relatively high by regional standards, but the 10-day revision cycle means consumers absorb volatility with a short lag rather than immediately.
The Philippines deregulated its downstream oil sector in 1998 under the Oil Deregulation Law (Republic Act 8479). Pump prices are largely market-determined, with the Department of Energy monitoring and publishing weekly price data. The Philippines is a net petroleum product importer, making pump prices highly sensitive to international crude and product markets, freight costs, and the peso-dollar exchange rate.
EV transition and battery supply chains
Southeast Asia's EV story is increasingly tied to Chinese manufacturers seeking manufacturing bases outside mainland China. BYD, SAIC, and Great Wall Motor have all announced or opened manufacturing facilities in Thailand, which aims to become the "EV hub of ASEAN" under its 30/30 policy (30 % of vehicles produced to be zero-emission by 2030). The Thailand Board of Investment offers significant EV manufacturing incentives.
Indonesia is pursuing a different angle: leveraging its position as the world's largest nickel producer (nickel is a key battery cathode material) to attract battery and EV manufacturing investment. LG Energy Solution, CATL, and Hyundai have all committed to battery projects in Indonesia. The government's ban on raw nickel ore exports — forcing downstream processing — is designed to capture more value from the EV supply chain.
As EV uptake grows, it will reduce petrol demand in urban centres — similar to the dynamic already visible in China (see our China fuel demand article) and beginning in India (see our India CNG vehicles article). The IEA Global EV Outlook 2024 projected Southeast Asia as a key growth market for two-wheel and three-wheel EV adoption from 2025 onward.
JETPs and clean energy financing
Just Energy Transition Partnerships (JETPs) are a mechanism developed at COP26 to mobilise concessional finance for coal-dependent developing countries to accelerate their energy transition. Indonesia (USD 20 billion) and Vietnam (USD 15.5 billion) are the two Southeast Asian JETP signatories. The UNFCCC JETP portal tracks programme status.
The JETP connection to fuel prices is indirect but real. If the JETP accelerates renewable power deployment, it reduces the need for gas and oil in power generation — freeing domestic gas supply for industrial and transport use, potentially moderating CNG prices. It also accelerates the EV charging infrastructure that underpins faster petrol demand displacement. The COP28 coverage discusses JETP progress in broader context, and the carbon tax article explores how carbon pricing and clean energy finance interact.
Frequently asked questions
Why does Southeast Asia have such varied fuel prices?
The region spans countries at different income levels with very different policy regimes. Indonesia heavily subsidises fuel through Pertamina. Vietnam uses a stabilisation fund. The Philippines follows market pricing. Singapore has high taxes and no subsidies, putting it at the top of the range.
What is Indonesia's fuel subsidy and how does it work?
Indonesia subsidises Pertalite (RON 90) and Solar (diesel) through Pertamina. The government compensates Pertamina for selling below market cost. In 2022 the subsidy bill exceeded USD 30 billion, forcing a price rise that triggered street protests.
Is Southeast Asia moving toward electric vehicles?
Unevenly. Thailand targets 30 % EV sales by 2030 and is attracting Chinese EV manufacturers. Indonesia is leveraging nickel reserves for battery supply chains. Vietnam and the Philippines are earlier-stage. Fuel subsidies that keep petrol cheap slow EV adoption economics.
What is the JETP and how does it affect Southeast Asian fuel prices?
JETPs provide concessional finance for coal phase-down. Indonesia (USD 20 bn) and Vietnam (USD 15.5 bn) are signatories. Faster renewable power deployment reduces gas and oil use in generation, potentially freeing domestic gas supply for transport and moderating CNG prices long-term.
