Nigeria Revenue Service Chairman Zacch Adedeji has identified fuel subsidy, an opaque foreign exchange market, an underperforming oil sector and a narrow tax base as four major economic distortions inherited by the Tinubu administration. Adedeji listed the distortions as an unsustainable fuel subsidy regime, an opaque foreign exchange market, an underperforming oil sector and a narrow tax base. He disclosed during an appearance on Channels Television’s Sunday Politics, where he defended the Federal Government’s economic reforms and argued that Nigeria’s fiscal position was improving. He also argued that the foreign exchange system discouraged investment, while weak oil-sector performance limited earnings from one of Nigeria’s most important sources of government revenue and foreign exchange. His comments come as the Tinubu administration continues to defend the reforms introduced since 2023, including the petrol subsidy removal, foreign exchange reforms and changes to the tax system.
