Spain is seeing September 2026 noticeably rising fuel prices. Official average figures from Madrid show that Diesel as well as 95-octane petrol and 98-octane petrol have become more expensive since the summer. More than 12,000 petrol stations regularly report their prices to the Ministry for the Ecological Transition and the Demographic Challenge, making regional differences clearly visible. Prices range from cheaper deals in highly competitive urban networks to higher prices in sparsely populated areas with longer supply chains.
Rising fuel costs are driving up inflation. Official figures put inflation at 4.9 per cent in September, its highest level since February 2023. The main reasons cited are more expensive crude oil and higher energy imports. A precise forecast for the fourth quarter is uncertain and depends above all on international crude oil prices.
The central government is maintaining the tiered relief at the pump approved in the summer. The previously approved price reduction is October 20 cents per litre, falling to 13 cents in November and 6 cents in December. The measure is part of a broader package to ease the impact of energy prices on households and businesses and was published in the Boletín Oficial del Estado No further expansion of the scheme has been announced at present, and any such move would depend on future price developments.
Despite the discount, the regional price differences remain marked. They reflect varying local competitive conditions, transport and storage costs, and the structure of petrol station networks. Larger urban areas, with a denser choice of providers, tend to have lower prices, while in outlying areas fixed costs and longer journeys push up the price per litre.
For consumers, the discount temporarily cushions the price surge but does not alter the underlying volatility. Businesses with a high share of diesel in their cost base feel the relief directly, but still have to plan for fluctuating operating costs. If oil prices remain high or rise further, the national averages currently being reported could climb again in the autumn. Conversely, a fall in crude oil prices would soon be reflected in reported pump prices.
The figures quoted here are based on the latest reports from petrol stations to the competent authority and the most recent official price and inflation data from Madrid.
