Cambodia Commits Nearly $500 Million to Energy Relief as Petrol Prices Rise Again

Energy relief approaches $500 million as fuel costs keep climbing

Cambodia has committed nearly $500 million to cushioning fuel and electricity prices, Prime Minister Hun Manet said on October 7, 2026, as rising international energy costs put pressure on consumers and the state budget. Days later, the Ministry of Commerce announced another increase in regular petrol prices, showing that government intervention has softened the shock without stopping it.

For October 11 to 21, regular petrol is priced at 5,350 riel per litre, up from 5,150 riel in the previous pricing period. Diesel moves in the opposite direction, falling to 5,550 riel from 5,650 riel. The latest prices leave petrol 38.9% above its level before the West Asia conflict began in late February, and diesel 44% higher, according to figures attributed to the ministry.

Hun Manet said the government had prevented fuel prices from rising another 9% to 10% through subsidies and tax relief. The nearly $500 million covers intervention in both fuel and electricity, rather than a single petrol subsidy. It includes reductions in fuel import tariffs and support for electricity prices.

The prime minister described the spending as a response to pressures on public health and household finances. He said revenue collected through customs and taxes was funding the measures, while other demands, including conflict and flood damage, were competing for the same resources.

He put the scale of the energy intervention this way:

Our total expenditure so far stands at nearly $500 million, just to cushion the prices of fuel and electricity for the people.

What changed at the pumps

The latest price adjustment separates two fuels that had both become much more expensive. Regular petrol rises by 200 riel per litre for October 11 to 21, while diesel falls by 100 riel. The announced changes are reported as a 3.8% increase for petrol and a 1.7% decrease for diesel.

For a purchase of 20 litres, the new petrol price means paying 107,000 riel, compared with 103,000 riel at the preceding price. The same quantity of diesel costs 111,000 riel, down from 113,000 riel. These calculations show the immediate effect of the adjustment without assuming how much fuel a household or business uses.

Before the latest change, petrol at 5,150 riel was reported to be 33.7% above its preconflict level, while diesel at 5,650 riel was 46.7% higher. The subsequent figures of 38.9% and 44% show petrol continuing to climb while diesel gives back a small part of its earlier increase.

Dollar equivalents differ between accounts. The earlier petrol price of 5,150 riel is given as both $1.29 and $1.27. The latest announcement reports petrol at $1.31 and diesel at $1.36. The riel prices provide the consistent basis for comparing the two pricing periods.

How subsidies and tax cuts reduce the bill

Cambodia's intervention combines reductions expressed as a fixed amount per litre with changes to several taxes. A continuing reduction of 6.5 US cents per litre is supplemented by another 1 cent after international petrol prices exceeded $90 per barrel and diesel prices exceeded $100 per barrel.

The government also reduced additional taxes on petrol and diesel to zero as international energy, transport and insurance costs increased. The special tax on petrol was cut from 30% to 15%, while the corresponding diesel tax fell from 4% to zero.

Value added tax, a tax applied to sales, was reduced from 10% to 4% for petrol and from 10% to zero for diesel. The government is covering a remaining tax burden described as equivalent to 6% for petrol and 10% for diesel.

These measures work through different parts of the price calculation. A reduction per litre lowers the charge by a fixed amount, while a lower tax rate changes the tax applied to the relevant taxable value. The percentages should not simply be added together as though they represent one discount on the final retail price.

Hun Manet also described the intervention as preventing an additional increase of 500 to 600 riel per litre. Applied illustratively to the earlier petrol price of 5,150 riel, a 9% to 10% increase would amount to about 464 to 515 riel. At the earlier diesel price of 5,650 riel, it would amount to about 509 to 565 riel. Those calculations broadly match his account of the relief.

The estimate describes what the government says prices would have been without support. It does not mean consumers have avoided increases altogether, as the price changes since February demonstrate.

A larger import bill adds to the pressure

Figures attributed to the General Department of Customs and Excise show Cambodia spending $3.38 billion on imports of mineral fuels, oils and related products between January and August 2026, compared with $2.41 billion in the same period a year earlier.

That is an increase of $970 million, or about 40.2%, consistent with the reported growth rate of 40%. The category is broader than petrol and diesel. It also includes distilled products, bituminous substances and mineral waxes, so the total should not be read as spending solely on fuel sold at filling stations.

The figures measure the value of imports, not their physical volume. They therefore cannot establish how much of the increase came from higher prices and how much came from changes in quantities purchased.

Cambodia relies entirely on imported petroleum and diesel, while its offshore oil reserves remain unexploited. That dependence exposes the domestic fuel bill to international prices and the costs of bringing products into the country. Subsidies can reduce what consumers pay, but they do not remove the underlying import expense.

Why electricity also needs support

The nearly $500 million figure includes electricity because part of Cambodia's power supply remains exposed to fossil fuel prices. Hun Manet said more than 30% of domestic power generation capacity relies on coal and heavy fuel oil, making production costs vulnerable to movements in those markets.

Hydropower and other renewable sources provide some protection from international oil price changes. Figures attributed to the Ministry of Mines and Energy put renewable energy at 63.23% of electricity generation in 2025. Hydropower contributed 34.25%, solar 28.05% and biomass 0.92%. The listed components total 63.22%, a difference of 0.01 percentage point from the stated total.

Generation and capacity measure different things. Capacity is the amount of power equipment can produce under specified conditions; generation is the electricity actually produced over a period. The figures for fossil fuel capacity and renewable generation therefore should not be treated as directly matching parts of one calculation.

The ministry's target is to raise the renewable share to at least 70% by 2030. Against the stated 2025 share of 63.23%, reaching that threshold would require an increase of at least 6.77 percentage points.

A greater renewable share would reduce exposure to imported fuel prices for part of the electricity supply. It would not, by itself, eliminate Cambodia's dependence on imported petrol and diesel for transport, or the need to manage costs at power plants that continue to burn coal and heavy oil.

Transport, food and household spending feel the strain

The price increases reach beyond motorists. Fuel is an expense for moving goods and operating businesses, while electricity costs affect production. Government relief is intended to limit the pressure those expenses place on household purchasing power and business costs.

Thong Mengdavid, deputy director of the China-Asean Studies Centre at the Cambodia University of Technology and Science, said higher energy costs were affecting logistics and manufacturing. He identified food and agricultural products as particularly exposed:

This surge is driving domestic inflation and eroding consumer purchasing power, with food and agricultural products taking the hardest hit,

His assessment describes the wider economic pressure, but no inflation rate or measured change in food prices accompanies it. The fuel price figures establish the scale of the increase at the pump; they do not establish exactly how much has been passed through to other goods.

The distinction matters for judging the intervention. Keeping fuel below the price it would otherwise reach can soften pressure on transport and production costs, even while consumers continue to face higher bills than before the conflict.

The budget faces several demands at once

Hun Manet said Cambodia was managing the effects of the Middle East crisis alongside border conflicts and flooding. Customs and tax revenue used for energy relief is also needed for other public spending, including repairs to damaged infrastructure.

He said unexpected conflict costs had increased expenditure and described severe flooding that destroyed roads and cut off national routes. His account referred to flooding during negotiations over the 2026 budget, but did not give a precise date for that episode or a separate repair bill.

The nearly $500 million total has other limits as a measure of the fiscal cost. No start date for the cumulative spending was specified, and no breakdown was given between electricity subsidies, fuel support and tax reductions. Direct spending and revenue forgone through tax relief both affect public finances, but they are different accounting categories.

The prime minister said the energy figure did not include the cost of responding to other problems. It therefore represents one area of government intervention rather than the full cost of the concurrent crises.

What is confirmed, and what comes next

Accounts differ on the setting of Hun Manet's remarks. One places him at the University of Health Science's 80th anniversary celebration in Phnom Penh on Wednesday morning, October 7. Another describes a University of Health Sciences graduation ceremony, while a separate report places a graduation ceremony in Battambang province. Those descriptions do not establish a single agreed venue or occasion.

The sequence of the principal developments is more definite:

• Late February 2026: The West Asia conflict marks the benchmark used for the subsequent fuel price increases.
• January to August 2026: Imports of mineral fuels, oils and related products reach $3.38 billion, up from $2.41 billion a year earlier.
• October 7, 2026: Hun Manet says nearly $500 million has been committed to cushioning fuel and electricity prices.
• October 11 to 21, 2026: Regular petrol is priced at 5,350 riel per litre and diesel at 5,550 riel.
• 2030: The Ministry of Mines and Energy targets a renewable electricity share of at least 70%.

Hun Manet said subsidies would remain in place while global fuel markets stayed elevated. No fixed end date, price threshold for withdrawing the wider support package, or total spending ceiling was specified. The announced retail prices cover October 11 to 21; prices beyond that period are not yet given.

Looking toward 2027, the prime minister called for preparation for further adverse developments. He framed that preparation in cautious terms:

We hope that the worst will not come, but we must prepare in advance.

The immediate position is that Cambodia is absorbing part of the energy price shock through its budget, while consumers still face substantial increases. How much further support will cost depends on international market conditions and the duration of the measures, neither of which has a settled endpoint.
