Although nearly all poor countries are classified by the World Bank as IDA-only, Nigeria stands out as a notable exception. Indeed, Africa’s most populous country is the poorest country in the world that is not classified as IDA-only. Under the World Bank’s own criteria, however, Nigeria has a strong case for reclassification. IDA-only status would have two potential benefits for Nigeria. First, it would expand Nigeria’s access to IDA resources and make the country eligible for grants. Second, it would strengthen Nigeria’s case for debt reduction. With a renewed economic reform effort getting under way and the emerging use of debt reduction as a tool for assisting economic and political transitions, the UK, the US, and other official creditors should support such a move as part of a broader strategy for encouraging progress in one of Africa’s most important countries.
