In Spain fuel prices have stabilised at a high level ahead of the Operación Salida on 15 August. According to data published on 12 August 2026 by the Geoportal Gasolineras of the Ministerio para la Transición Ecológica the average price of diesel was €1.806 per litre and petrol €1.691 per litre.
Prices are therefore close to levels seen in the first days of August. Diesel averaged €1.818 at the start of the month, and petrol €1.705. For motorists, the current prices mean that a typical 55-litre tank costs around €99.3 for diesel and about €93 for petrol. (Data as at 12 August 2026.)
The current figures are not a new high for the year. The peak was recorded on 21 March 2026 , when diesel averaged €1.942 per litre and petrol €1.796. Market observers have repeatedly cited tight conditions in the crude oil market and geopolitical risks in the Middle East as factors that caused price spikes at times. Even so, the current sideways movement offers some predictability ahead of the summer travel period, although prices remain high compared with previous years.
Context: Spain publishes average retail prices daily through the Geoportal Gasolineras. The overview is based on reported pump prices and serves as a reference for authorities, market participants and consumers. Travel and demand peaks around the Operación Salida can cause regional fluctuations; prices do not necessarily move uniformly across the country during this period.
Facts: The stated average prices for diesel (€1.806 per litre) and petrol (€1.691 per litre), the comparison figures from the first week of August, and the highs of 21 March 2026 come from the official price database of the Geoportal Gasolineras (data as at 12 August 2026). The cost examples are based on a 55-litre tank and are calculations only; they do not indicate the amount any individual would pay at a particular station.
Attributed statements: References to the role of international crude oil prices and geopolitical risks come from explanations commonly given by market observers; they are not official findings.
Forecasts: Over the coming weeks, developments will depend on crude oil prices, supply and seasonal demand. Short-term fluctuations are possible, particularly around the Operación Salida, but no reliable forecast can be drawn from this.
