In the last few days,especially after the National Bureau of Statistics (NBS) released its figures on the rebased CPI , which indicated a reduction in inflation figures from 32.5% in December 2024 to 24.5% in January 25, experts have reasonable predicted a considerable difference in the rebased GDP figures when it is released which was last released in 2014 using the base year of 2010. Between 2010 and 2019 , a period of about 9 years, must have understandable changed the structure of the Nigerian economy.

Generally speaking ,GDP rebasing would mean updating the base year used to calculate the Gross Domestic Product (GDP) to reflect current economic realities. When Nigeria last rebased its economy in 2014, updating the base year from 1990 to 2010, it led to a significant increase in the reported GDP. It is reasonable to assume therefore,that as Nigeria undertakes another rebasing exercise, there are few things to expect.

First of all there will be a likely increase in GDP Size. The economy may appear larger than previously reported due to the inclusion of new and fast-growing sectors like fintech, e-commerce, entertainment, and digital services.
