Prices rose 3% year on year in September: fuel driving inflation
According to the flash estimate published by Statistics Estonia on October 2, consumer prices in September rose 0.5% compared to August and 3% compared to September last year (ERR, October 2, 2026). The main driver of the price rise was the increasing cost of petrol and diesel. This affects anyone who fills up a car or pays heating bills.
What Statistics Estonia reported exactly
Lauri Veski, service manager for consumer price statistics at Statistics Estonia, told ERR that the September index was mainly affected by the continuing rise in petrol and diesel prices, driven by the military conflict in the Middle East. This is a preliminary flash estimate; exact figures will be published by Statistics Estonia on October 7.
Lenno Uusküla, chief economist at Luminor, added that seasonally adjusted, the harmonised consumer price index grew 0.9% compared to August, and the annual rate of inflation rose from 1.3% in August to 3% in September. Part of the jump comes from the fact that last year's September price drop of 0.7% dropped out of the calculation base.
Why fuel got more expensive right now
Uusküla explained that fuel was temporarily cheaper over the summer, which is why both world market prices and prices at Estonian filling stations rose quickly in September. In addition to the price of oil, diesel availability created problems, which is why the diesel price increase was larger than that of petrol.
Raul Eamets, chief economist at Bigbank, pointed to broader risks: the ongoing oil and gas crisis, uncertainty around the Strait of Hormuz, and the actions of the Houthis in Yemen, who have blocked shipping through the Bab el-Mandeb Strait. According to him, nearly a quarter of the world's maritime transport passes through these two straits, and disruption there raises the price of oil, gas, and other goods arriving by sea from Asia.
What this means at the pump
When fuel prices rise, everyday driving costs grow directly as well. As an example, consider a driver who covers 1,500 kilometers per month with an average fuel consumption of 7 liters per 100 km, meaning 105 liters are used per month. If the diesel price rises from, say, 1.55 euros to 1.60 euros per liter (a 5-cent increase per liter), the monthly cost for 105 liters grows by 5.25 euros, or roughly 63 euros per year. You can work out your own exact cost and the impact of a price change using the fuel cost calculator, by entering your mileage, fuel consumption, and the current price per liter.
Since, according to Eamets, more expensive diesel sooner or later feeds through into transport costs and therefore into final consumer prices, the impact doesn't stay at the filling station but spreads more broadly into food and other goods prices.
What a 3% price rise means for your budget
In simple terms, a 3% annual price increase means that a basket of goods that cost 100 euros a year ago now costs about 103 euros (100 × 1.03). If a household's monthly consumption spending is, say, 1,200 euros, the same 3% increase means roughly 36 euros in extra costs per month, assuming the basket and quantities stay the same. You can quickly check how much a specific price change in percentage terms affects your own expenses using the percentage calculator.
If income doesn't grow at the same time, this effectively means a drop in purchasing power. This is a good moment to review whether your household budget and savings plan are keeping pace with the rate of price increases, for example, the savings calculator lets you check whether your current monthly savings amount will still cover the same goal once prices are higher.
What economic analysts say about what comes next
In Uusküla's view, September's rapid increase may not be a lasting trend, since part of it stems from one-off factors, and the world market price of oil is already lower now than it averaged in September, continuing on a downward trend. At the same time, he stressed that the decline won't be even, and further periods of price increases may still occur.
Eamets is more pessimistic, saying that looking toward autumn there is no reason to expect inflation to slow down. The reason is the ongoing energy crisis, along with growing demand for heating and electricity as autumn progresses, which is also pushing up the prices of gas, pellets, and firewood. In his view, Estonia can expect inflation to accelerate this autumn, so it's worth reviewing the share of the household budget spent on fuel and heating right now, rather than waiting for the bills to arrive.
