Greek consumers paid more than €400 million ($469 million) in additional fuel costs for gasoline, diesel and heating oil during the first two months of the conflict in Iran, as higher international oil prices pushed pump prices sharply upward.
The increase has raised fresh concern in the domestic fuel market, especially as the fragile ceasefire in the Middle East remains at a critical point and international oil prices continue to move steadily above $110 per barrel.
Fuel price hikes for Greek consumers also boosted state coffers
While households and businesses faced a heavier fuel bill, the state also collected higher revenues. Surplus tax revenue linked to higher fuel prices exceeded €90 million in March and April combined.
That amount falls only €15 million ($17,6 million) short of the total public cost of the two-month diesel subsidy, which stood at 20 cents per liter for April and May.
March cost consumers up to €185 million more
In March, consumers in Greece paid an estimated €170 million ($199 million) to €185 million ($217 million) more for fuel than they would have paid at prices recorded before the start of the war in Iran.
Fuel trading companies made the estimates based on official consumption data from the Ministry of Environment and Energy for gasoline, diesel and heating oil.
Surplus revenue from fuel consumption tax in March reached an estimated €35 million ($41 million) to €38 million ($44 million).
Motor fuel consumption, including gasoline and diesel, remained almost unchanged compared with March 2025, recording a marginal increase of 0.7%. Heating oil formed the exception, with sales rising 8.5% year over year. The increase suggests that consumers, fearing further price hikes, moved early to stock up for the next winter season.
April added at least €250 million to the fuel burden
In April, using 2025 consumption as the reference point, higher fuel prices added at least €250 million ($293 million) to €260 million ($305 million) to consumers’ costs.
The Ministry of National Economy and Finance is expected to announce official April consumption data on May 20. However, unofficial sales data from fuel trading companies points to increased consumption during the month.
The state collected an estimated €54 million ($63 million) in surplus revenue in April.
Greek Consumers saw fuel prices for gasoline and diesel rise sharply
At the pump, gasoline rose from €1.75 ($2.05) per liter one day before the war in Iran to €2.06 ($2.41) per liter last Friday, marking an increase of 18.1%.
Diesel also climbed significantly, rising from €1.56 ($1.83) per liter to €1.88 ($2.20) per liter over the same period.
