Nigeria’s December 2025 inflation figures have been projected to experience an artificial spike due to a technical base effect.
The ‘artificial spike,’ the National Bureau of Statistics (NBS) explained, does not reflect the country’s inflation dynamics but rather a statistical rebasing, which it said is ‘one-off.’
“Projections show that without adjustment, December year-on-year inflation could appear excessively high due solely to arithmetic base effects, rather than underlying economic conditions,” Ayo Anthony, head of price statistics at the NBS, said during a stakeholder engagement organised by the Nigerian Economic Summit Group on Monday, ahead of the official release of the data on Thursday.
