Data from the Hungarian Petroleum Association (MÁSZ), whose members account for about three-quarters of the country's petrol market and two-thirds of the diesel market, show vehicle fuel sales climbed 17% in December, the paper said.

MÁSZ chief secretary Ottó Grád acknowledged the price cap as "one of the main reasons" for sales growth in 2021. MÁSZ members' vehicle fuel sales increased 5.4% to 3.81 billion liters last year.

Sales of 95-octane gasoline rose 5.9% to 1.132 billion liters and diesel sales climbed 6.6% to 2.377 billion liters.

Sales of premium gasoline, which weren't affected by the price cap, dropped 4.7% to 300 million liters.
