Spain’s inflation jumps to 4.3%: what the fuel-driven surge means for autumn bills

This month, petrol pumps have almost single-handedly rewritten Spain’s cost of living. The country’s headline inflation rate leapt to 4.3 per cent in the month of August, its highest reading in more than three years, even as the pressure on everyday prices away from fuel actually eased. 

Inflation breaks past 4% for the first time since 2023

Spain’s National Statistics Institute (INE) said on Friday that consumer prices rose 4.3 per cent in the year to August, up from 3.6 per cent in July and 3.2 per cent in June. It is the third month in a row the rate has accelerated, and the highest annual reading since February 2023, when inflation stood at six per cent.

It builds directly on last month’s jump, when fuel and electricity costs pushed the rate to what was then a two-year high of 3.6 per cent. August’s figure has now gone further, and it’s the first time inflation has climbed back above four per cent since April 2023. Prices rose 0.7 per cent between July and August alone, the sharpest month-on-month jump for August since 1992. INE’s figure is a provisional advance estimate for now; the confirmed reading follows on Tuesday September 15.

Fuel is doing almost all the damage

Fuel prices, which were falling at this point last year, have reversed sharply and are now pushing the index higher instead. INE linked the shift to the lingering effects of the energy shock triggered by the war involving Iran, which has kept oil markets unsettled since March. 

Diesel is now running around 21 per cent more expensive than a year ago, according to separate market tracking, even though the underlying price of crude oil has fallen in recent weeks. However, refining and distribution costs have kept pump prices high regardless. A litre of diesel in Spain currently costs around €1.86, with petrol at about €1.72, on Friday August 28. 

The number that’s moving in the opposite direction

Strip fuel and fresh food out of the equation, though, and the picture looks quite different. The cost of everything else actually rose a little more slowly in August than it did in July, therefore this month’s jump comes almost entirely from the price of fuel, rather than a broader rise in the cost of living.

Food and non-alcoholic drinks are still helping to keep prices down overall, just not by quite as much as they were a year ago, a smaller effect that has itself nudged the wider rate a little higher.

What it means for autumn bills

Some relief should soon be felt. Because diesel prices have stayed above the government’s 15 per cent trigger threshold for two months running, the automatic tax discount on diesel rises from 10 cents to 20 cents a litre from September, with the discount on petrol increasing to five cents.

It won’t undo August’s jump, but it should soften the blow of filling up just as households start planning for autumn: heating bills, the school run and the return to normal routines after summer. The squeeze also comes as mortgage repayments have been rising across the country, with monthly bills for many homeowners already up around €65 as the Euríbor nears three per cent. Economists will now be watching September 15 closely to see whether four per cent turns out to be a peak, or the new normal.
