The price of cooking gas has risen sharply across Nigeria, climbing from N1,200 to N1,500 per kilogramme, amid another increase in the cost of diesel.
The 25 per cent rise in liquefied petroleum gas prices comes as Automotive Gas Oil, popularly called diesel, sells for as much as N2,300 per litre at some filling stations and depots, further raising energy costs for households and businesses.
The latest mid-day depot price report for Wednesday, September 16, 2026, showed that diesel prices increased in major markets, particularly Lagos and Port Harcourt, while some petrol prices remained relatively stable.
In Lagos, Ibachem recorded the biggest increase among the listed depots, moving its AGO price from N1,830 to N2,000 per litre. Ibeto also raised its price to N1,970, while Duport and Integrated moved to N1,940 per litre.
The upward trend was also recorded in Port Harcourt, where African Terminal, Duport and Integrated increased their diesel prices to N1,940 per litre. In Warri, Matrix raised its price from N2,080 to N2,120, the highest depot price captured in the report.
The development is expected to increase operating expenses for manufacturers, transporters, telecommunications firms and small businesses that depend on diesel-powered generators and vehicles.
Despite the diesel increases, petrol prices showed less movement in several locations. In Lagos, prices hovered around N1,350 to N1,353 per litre, while some marketers in Calabar and Warri recorded modest reductions.
Vice-President of the Oil and Gas Service Providers Association of Nigeria, Lawal Kamaldeen, said the downstream petroleum market remained unstable, attributing the fluctuations to international developments.
He told Vanguard, “The downstream sector has been very unstable, characterised by frequent leaps in prices due to the prolonged USA-Iran war. Prices are likely to continue to be unstable in the coming weeks.”
