Fuel subsidy: how governments keep pump prices low
A fuel subsidy is government support that keeps the pump price below what fuel would cost at market rates. The gap between the two is covered by the state, one way or another, rather than by the driver. It's distinct from a low tax rate or a government-fixed price, though the three often overlap.

What a fuel subsidy is — meaning, definition, and examples
What is fuel subsidy? A fuel subsidy is any government intervention that keeps the retail price of fuel below its true market cost. The meaning of fuel subsidy is simple: the state covers some or all of the gap between the pump price consumers pay and the full cost of supplying the fuel — crude oil, refining, distribution, and applicable taxes. In practice, fuel subsidy can take the form of a direct cash transfer to the state oil company, a waiver of excise duty or VAT, or a government-enforced price cap set below the import parity price.
The IMF defines a fuel subsidy as the gap between what consumers pay and the full supply cost including taxes and externalities. Countries like Iran, Venezuela, and Libya have historically provided the largest explicit fuel subsidies relative to GDP. The fuel subsidy meaning therefore differs from a "low tax rate" — a government can have zero fuel duty and still not subsidise fuel; a subsidy only exists when the price is held below the underlying cost.
It's a specific mechanism, distinct from a low tax rate or a government-fixed price, though the three often appear together in practice; a country can have any combination of them.
Different kinds of fuel subsidy
Subsidies aren't all structured the same way, and the distinctions matter for understanding who bears the cost and how it's counted.
How the size of a subsidy is estimated
International organisations that track fuel subsidies, including the IMF and IEA, commonly estimate their size using a price-gap approach: comparing the domestic price against a reference international price for the same fuel.
Illustrative example, not a real country's figures. The gap, multiplied by the volume consumed, gives a rough estimate of the total subsidy.
Who ends up paying for it
The cost of a subsidy has to be covered somewhere, even when it isn't visible at the pump.
Why subsidies are hard to remove
Economists and international institutions have long pointed to fuel subsidies as costly and, in some analyses, regressive, since higher-income households with more vehicles often capture a larger share of the benefit than lower-income ones. Governments weigh that against the immediate, visible cost of removing support that households and businesses have priced into their budgets.
Cutting a long-standing fuel subsidy raises the pump price all at once, which is felt immediately by drivers, transport operators and, indirectly, the prices of goods that depend on transport. A number of countries that have attempted subsidy reform have partly or fully reversed it after public pushback, which is one reason subsidies can persist for decades even when their fiscal cost is well known.
How this shows up on FuelTheGuide
We label a country's fuel prices as subsidised where the underlying data source identifies it that way, so you can filter subsidised markets in or out of a comparison.
We label a country as subsidised where the underlying source identifies it that way. We don't calculate a subsidy amount or price gap ourselves.
Questions and answers
Fuel subsidy meaning and fuel subsidy examples worldwide
Fuel subsidy meaning in its simplest form is any government intervention that keeps the retail price of fuel below its true market cost. Fuel subsidy examples range from direct cash transfers to state oil companies (Iran, Venezuela) to reduced excise duty rates (many EU countries apply lower rates to diesel and LPG) to price caps enforced at the pump (Indonesia, Malaysia, Egypt). The IEA's energy subsidies tracker provides country-by-country data on fossil fuel subsidies, while the U.S. EIA's international energy overview tracks how subsidised markets interact with global crude oil pricing.
The scale of global fuel subsidies is enormous — the IMF estimated total fossil fuel subsidies (explicit and implicit, including unpriced externalities) at approximately USD 7 trillion in 2022. Explicit fuel subsidy examples — where governments directly fund the gap between market and pump prices — are concentrated in oil-producing nations like Iran, Saudi Arabia, Algeria and Venezuela, and in large emerging markets like Indonesia, India and Egypt. Subsidy reform is one of the most politically sensitive energy policy areas, because removing support immediately raises prices for consumers. The OPEC Annual Statistical Bulletin provides context on how subsidised domestic consumption in producing countries affects global export availability.
Is a subsidised price the same as a government-fixed price?
Not necessarily, though the two often go together. A fixed price is one set by decree rather than the market; a subsidy is support that keeps a price, fixed or otherwise, below the underlying cost. A price can be fixed without being subsidised, and in principle a market price could carry a subsidy too.
How is the size of a fuel subsidy actually measured?
The most common approach is the price-gap method: the difference between the domestic pump price and a reference international price for the same fuel, multiplied by the volume consumed. Organisations like the IMF and IEA use this method, though they may use different reference prices and coverage assumptions, which is why estimates vary.
Do rich countries subsidise fuel too?
Yes, in several ways. Direct subsidies are less common in high-income countries, but many provide tax exemptions or reduced duty rates for certain fuel uses — agriculture, aviation, fishing — that amount to an implicit subsidy. Some also have periods of direct price support during energy price spikes. The IEA's fossil fuel subsidy tracker covers both explicit and implicit support across advanced and emerging economies.
Why don't more countries just remove fuel subsidies if they're costly?
Because removing a subsidy immediately raises the pump price, which is felt quickly by drivers and transport operators. Governments that have tried often face political pushback, and in some cases have reversed the cuts. Gradual removal with targeted support for low-income households is generally more durable, but harder to design and implement.
What is the meaning of fuel subsidy?
The meaning of fuel subsidy is any government action that keeps the retail price of fuel below its true market cost. What is fuel subsidy in practice? It can be a direct cash transfer to the state oil company, a waiver of excise duty or VAT, or a government-enforced price cap below the import parity cost. The IMF defines a fuel subsidy as the gap between what consumers pay and the full supply cost including taxes and externalities. Countries like Iran, Venezuela, and Libya have historically provided the largest explicit fuel subsidies relative to GDP — see our Middle East fuel prices article for regional context.
