Spanish motorists are bracing for a steep rise in fuel costs as state subsidies on gasoline and diesel expire at the end of September. With no confirmed extension, drivers are urged to refuel now to avoid paying even more at the pump in October.
Drivers in Spain are up against a deadline. The last day of September is the cutoff for government fuel discounts. After that, prices at the pump will jump. Anyone hoping for a last-minute extension is running out of time. The advice is simple: fill up now or pay more next month.
Gasoline 95 has gone up by 0.48 euros per litre in just three months. That is about a 33% increase. Diesel has climbed by 0.35 to 0.40 euros per litre, which means a 23–27% rise since late June. These steady price hikes have left many drivers unsure what to do. Some hope prices will drop, but the market keeps moving up.
In September, Spain maintained a 5-cent discount per litre for gasoline and a 20-cent discount for diesel, with an additional professional diesel support of 200 euros per 1,000 litres.
The real hit comes from the government letting its fuel aid package end on September 30. Until now, drivers got a 5-cent discount per litre on gasoline and 20 cents off diesel. The government says it is still talking with unions, businesses, and other groups about possible extensions or new measures. But so far, nothing has been decided.
Recent changes in the law have already chipped away at the relief. Real decree law 18/2026, passed in June, shifted the focus of subsidies to the hydrocarbon tax and put VAT on fuel back to 21%. The discounts have been shrinking: 15 cents per litre in July, 10 in August, and just 5 in September. This was meant to phase out support unless inflation spiked. There is a safeguard clause that could have raised the discount to 20 cents if fuel inflation went over 15%, but that is not set to happen in October.
With the official support ending, the government says it is watching the economic fallout from the conflict in Iran "minute by minute." For drivers, the message is blunt. The current discounts are about to disappear. Waiting for a better deal is a risk most people cannot take.
According to industry reports from IRU, diesel prices in Spain have recently reached seasonal highs, and the end of state support removes the automatic mechanism that could have extended or increased the discount in October. This puts additional pressure on professional drivers and sectors like agriculture and fisheries, which also lose targeted aid as part of the broader anti-crisis package.
Spain is not alone in this fuel price crunch. The squeeze on household budgets has already pushed supermarkets to cut prices on basics, as shown in the recent drop in olive oil prices. But fuel prices are set by global markets and government rules. Consumers have little control.
With state aid about to end, Spanish drivers face a tough reality. Unless the government changes course at the last minute, October will bring higher fuel bills for millions. The only sure way to avoid the worst is to fill up now. In these uncertain times, what you do at the pump matters—and the window to act is closing fast.
