Dangote Refinery has raised its petrol price four times since August 21. Crude above $100 a barrel, with Middle East supply disruption a major driver, is putting upward pressure on what a locally refined litre of petrol costs.

On Saturday, Dangote Petroleum Refinery raised its petrol gantry price from N1,265 to N1,350 a litre, an increase of 6.7 percent. It was the fourth increase since August 21. The refinery moved from N1,165 to N1,185 on August 21, to N1,200 on August 26, to N1,265 on August 29, and now to N1,350. In 22 days, the price has climbed N185 a litre, close to 16 percent.

Pump prices followed within hours. At an MRS station in Alapere, Lagos, petrol reached N1,395 a litre, up from N1,310. A Mobil station on the same road sold at N1,385. In Ogun State, prices moved more unevenly, with NNPCL stations in Ikeja at N1,380 and independent marketers in Ota between N1,305 and N1,340.

Transport fares moved with them. The fare from Atan to Ojuore in Ogun State rose from N1,000 to N1,200. A conductor on the route told Leadership why. "You don't even know how much I bought fuel today. The price has increased."

Crude has traded above $100 a barrel amid Middle East supply disruption, including Saudi infrastructure attacks, Houthi activity in the Red Sea and wider Strait of Hormuz shipping risk, none of which Nigeria has any say over. Dangote's refinery buys crude on international markets, and rising crude costs, alongside refining economics, FX and logistics, feed into what the refinery charges at the gantry. The refinery is the point where that global oil pressure reaches the Nigerian fuel market.

As recently as February, Dangote cut its gantry price to N774 a litre, citing shifting downstream market dynamics. Seven months later, that same gantry price has climbed more than 74 percent. A refinery that can cut its price in a calm month can raise it four times in a volatile one. The direction it moves depends less on anything happening inside Nigeria and more on what crude is doing on a given day in a market Nigeria doesn't set.

What makes this round different from earlier price movements is the pace. Four increases in 22 days leaves marketers, transporters and households no time to adjust before the next one lands. Diesel has moved with petrol, with Lagos ex-depot prices between N1,790 and N2,100 a litre, pushing inland prices in Abuja and the north toward N2,400 once trucking costs are added. Abuja and northern markets sit furthest from the coast, so they absorb both the price increase and the extra cost of moving fuel inland.

The chain from there is direct and already documented. Higher fuel costs raise the price of moving food from farms to markets. They raise school transport costs during a term that has already seen fees rise sharply on resumption. They raise the operating costs of the tricycles and buses that most Nigerians without cars depend on daily. None of that shows up on a Dangote circular. It shows up in what a commuter pays the next morning.

Victoria Ibezim-Ohaeri, executive director of Spaces for Change, said households would likely face higher transportation and food costs as the increase filters through the economy. That filtering doesn't happen on a schedule anyone controls. It happens as fast as a transporter can recalculate a fare or a trader can reprice a bag of garri, which in Nigeria's informal economy is often within hours, not weeks.

The Energy Bulletin published by Lagos's Industry Competency Centre put the seven-day average Brent crude price at $98.74 a barrel and Bonny Light at $104.65, against a seven-day average exchange rate of N1,323.12 to the dollar. Brent is set on international markets. The naira rate reflects both market pressure and CBN policy. Both feed into the economics of petrol sold in Nigeria.

Nigeria removed its fuel subsidy in 2023, arguing that a market-determined price would end the cycle of government-funded petrol and free up money for other priorities. Petrol prices no longer move on a political timetable set in Abuja. They move on a market timetable set wherever crude is trading that day, and they now reach Nigerian pumps faster than they did under subsidy, because there's no longer a government buffer between global crude and the price at the gantry.

A refinery built to end Nigeria's dependence on imported fuel has not ended the country's dependence on global oil prices. It has just moved the transmission point closer to home. When crude spikes now, Nigerians feel it within days instead of months, because the price no longer has to cross an ocean and a subsidy formula first. It only has to cross a gantry.
