Inflation in Spain rose sharply in August, reaching its highest level in more than three years. Rising fuel prices are the main driver behind the significant increase. At the same time, core inflation has sent a surprising signal.

Prices in Spain rose significantly faster in August than in the previous month. According to preliminary data from Spain’s National Statistics Institute (INE), the annual inflation rate stood at 4.3 per cent. In July, the inflation rate was still 3.6 per cent.
This puts inflation in Spain at its highest level since February 2023. The rate increased by 0.7 percentage points in just one month. The main reason for the rise can be found at the petrol stations: petrol and diesel have become significantly more expensive.
Fuel prices drive inflation
The development of fuel prices is having a significant impact on the current inflation rate. While petrol and diesel prices fell in August last year, they have risen this year.
This so-called base effect is further amplifying the rise in annual inflation. The impact is being felt immediately by motorists. Anyone who regularly relies on a car now has to budget significantly more for fuel.
However, the impact extends beyond motorists. Rising fuel prices also increase costs for transport companies, delivery services and other businesses that rely on vehicles. These additional costs can subsequently be passed on to consumers, at least in part.
Core inflation falls slightly
Despite the sharp rise in overall inflation, another key indicator shows a somewhat less dramatic trend. Core inflation fell from 3.0 per cent to 2.9 per cent in August.
Core inflation excludes particularly volatile components such as energy and certain food prices. It is therefore considered an important indicator of the underlying price pressures in the wider economy. The fact that core inflation has edged down despite the sharp rise in overall inflation suggests that the current surge in prices is being driven primarily by energy costs.
For the months ahead, the key question will therefore be whether higher fuel prices are merely a temporary effect or whether they will increasingly affect other areas of the economy.
Food prices also play a role
In addition to fuel prices, developments in food prices are also influencing the inflation rate. Although prices for food and non-alcoholic beverages fell in August, they did not decline as sharply as in the same month last year. A base effect is therefore also playing a role here.
For consumers, however, this does not necessarily mean that the situation is easing. What matters is how much an average household actually has to pay for its weekly shop. Particularly when it comes to food, even relatively small price changes can be noticeable for families.
Spain responds with diesel rebate
The Spanish government is seeking to cushion the impact of high fuel prices. From 1 September, the tax relief on diesel is due to be increased to 20 cents per litre. This represents a significantly higher level of support than originally planned. Petrol will also receive tax relief, with the reduction remaining at 5 cents per litre in September.
The measures are expected to benefit motorists, transport companies and other industries that are heavily reliant on diesel prices in particular. However, whether the relief measures actually lead to lower prices at petrol stations will also depend on developments in international oil prices.
Geopolitical tensions add to the pressure
The development is also being driven by the tense situation on international energy markets.
The war in Iran and the uncertainty surrounding it have put pressure on energy prices. For countries such as Spain, which rely heavily on international markets to secure their energy supply, such developments can quickly have an impact on consumer prices.
Rising oil prices initially make petrol and diesel more expensive. At the same time, higher energy costs can also increase the cost of producing and transporting goods. This creates the risk that a price shock initially confined to energy could gradually spread to other areas of the economy.
Inflation well above the ECB’s target
With an inflation rate of 4.3 per cent, Spain is now significantly above the European Central Bank’s medium-term inflation target of 2 per cent. The current development is therefore of considerable importance to the ECB.
However, the ECB is unlikely to focus solely on overall inflation. The key question is whether the current price increase will persist and begin to affect services and other goods as well. The slight decline in core inflation to 2.9 per cent suggests, at least for now, that this is not yet a fully broad-based new wave of inflation.
However, if energy prices remain high for an extended period, businesses could increasingly pass their higher costs on to customers. This could then cause core inflation to rise again.
What does this mean for people in Spain?
For consumers, the current development means one thing above all: the cost of living is rising again. People who regularly drive or rely on a vehicle for work are particularly affected, as higher fuel prices directly increase their monthly expenses.
Households without a car can also be affected indirectly. If transport, logistics and production become more expensive, businesses may pass these higher costs on to consumers through increased prices for goods and services.
How strongly an individual household actually feels the effects of inflation therefore depends largely on its personal spending habits.
No final figures yet
The published figure of 4.3 per cent is initially only a preliminary estimate. The final inflation figures for August are due to be released by the INE on 15 September 2026. The Harmonised Index of Consumer Prices (HICP) is also important for European comparisons. According to preliminary figures, it stood at 4.5 per cent in August.
Spain is therefore entering a new phase of significantly higher inflation. The key question now is how energy prices will develop over the coming months and whether the current surge in prices will remain confined to fuel.
August has already made one thing clear: developments at the petrol pumps have once again become one of the key factors driving inflation in Spain.
