Is Nigeria's official fuel pump price still official?

Nigeria churns out roughly 2 million barrels of crude oil a day, making it Africa’s top producer and the world’s thirteenth. But still, because of its feeble domestic refineries, Nigeria imports about 80 per cent of the gasoline it consumes at home, selling it at a government-fixed rate (US$0.43) that is below the international average price (US$0.97) and the landing cost determined by world oil price and cost of freight. The difference is finance in subsidy. For instance, in 2011 alone, the total subsidy amount was over $13 billion—about 3 per cent of Nigeria’s GDP that year; and N4.39 trillion last year, 2022.
