The price of domestic fuel oil in France depends on a chain of factors ranging from crude oil prices to refining margins and local taxation. Understanding this chain allows one to know whether the coming months offer a window to order at a lower cost, or if the market remains too tight to anticipate a lasting decline.
Crude oil market and global demand: the first link in the price of fuel oil
Domestic fuel oil is a medium distillate of crude oil, similar to diesel due to its refining process. Its price therefore first follows the evolution of the barrel price, before incorporating transformation, transport costs, and taxes.
In its Oil Market Report of October 2026, the International Energy Agency (IEA) forecasts a contraction in global oil demand in the fourth quarter. Economic slowdown and high prices are hindering industrial and road consumption in several major importing regions.
This contraction mechanically pushes crude prices down. For households wondering if the price of fuel oil will decrease, this is the first signal to watch: a falling barrel price will reflect, with a few weeks’ delay, on pump prices and the price per liter delivered to homes.
The IEA tempers this signal by estimating that the oil market will remain in deficit until the end of the year. OPEC+ production is not increasing quickly enough to offset the drop in demand with a surplus supply. Therefore, crude can decline without collapsing.
Diesel stocks and refining margins: the bottleneck that hinders the decline
A cheaper barrel of crude does not guarantee cheaper fuel oil. Between the two, there is refining, and this is where the mechanism gets stuck.
The IEA reports that global diesel exports decreased in September compared to the previous year. Global medium distillate stocks (diesel, domestic fuel oil, kerosene) were low before entering winter, a period when heating demand increases.
According to the agency, the replenishment of these stocks may not begin until the second half of 2027. This tension on the supply of refined products keeps refining margins high, which limits the transmission of the decline in crude prices to the end consumer.
In practical terms, two variables are working in opposite directions:
- The price of crude oil is falling due to the economic slowdown, which pulls the price of fuel oil down.
- Refining margins remain high because distillate stocks are insufficient, which partially offsets the easing of crude prices.
- French taxation (TICPE and VAT) represents a fixed part of the final price and does not decrease when crude prices fall.
The decline observed after the peak in September is real. Reports from the DGEC indicate that fuel oil prices dropped from around 1.94 euros per liter in mid-September to lower levels in early October. The trend exists, but it remains moderate.
Government announcement on strategic stocks: fuel oil or diesel?
In early October, a government announcement raised hopes for a decrease of nearly 200 euros on a typical order. Several media outlets reported it. The details of the statement deserve careful reading.
The official text concerns the release of strategic diesel stocks, not domestic fuel oil. Selectra highlighted this distinction: fuel oil and diesel are similar in composition, but their distribution circuits and tax levels differ.
An increase in diesel supply can indirectly ease the medium distillate market and lower fuel oil prices. The link exists, but it is neither automatic nor immediate. The promise of a 200 euro decrease relies on an indirect effect, not on a measure directly targeting domestic fuel oil.
For a household ordering around 1,000 liters, the difference between the September and October prices already represents several dozen euros. Waiting until November to benefit from a potential additional effect of strategic stocks remains a gamble: if winter sets in early, demand may rise again and negate the expected gain.
Domestic fuel oil in France: what trade-offs in the medium term
Beyond the current situation, the fuel oil market is under structural pressure. The installation of new fuel oil boilers is gradually being restricted, with a regulatory deadline around March 2027 for exemptions related to biofuel. This constraint reduces the number of fuel oil boilers and, ultimately, domestic demand.
For households still equipped, two options are available:
- Order before the winter peak if the price has already decreased compared to September, accepting that further declines remain uncertain.
- Consider replacing the fuel oil boiler with a heat pump or another system, utilizing existing aids (notably MaPrimeRénov’) to offset the investment.
- Split the order into two deliveries to smooth the risk of price variation, when the supplier allows it without prohibitive delivery costs.
The choice depends on the volume to be ordered, the condition of the tank, and the winter schedule. No analyst predicts a return to the low prices of before 2021 for domestic fuel oil in France, even in a scenario of prolonged easing of crude prices.
There are reasons to hope for a decrease: declining global demand, crude under pressure, possible effects of strategic diesel stocks on the distillate market. There are also obstacles: low refining stocks, inelastic taxation, and the approaching winter. The next weekly report from the DGEC will provide a clearer indication of the direction the market is taking at the start of the heating season.
