Nigeria’s debt challenge is increasingly defined not by the size of the debt stock but by the cost of servicing it. Debt-service obligations consume a significant proportion of government revenues, limiting the resources available for development priorities. Rising debt service obligations reduce fiscal space for growth-enhancing investments.

The country’s debt-service burden reflects:

  • obligations accumulated over multiple administrations;
  • repayments associated with Eurobond issuances;
  • bilateral and multilateral financing commitments;
  • domestic debt obligations; and
  • the higher naira cost of servicing foreign-currency debt following exchange-rate reforms.

The consequences are significant. As debt-service commitments consume a larger share of government revenues, the fiscal space available for critical investments becomes increasingly constrained. Debt-service obligations have emerged as the primary constraint on fiscal sustainability. This affects the government’s capacity to fund:

  • roads and transport infrastructure;
  • power projects;
  • education;
  • healthcare;
  • security operations; and
  • social intervention programmes.

 

Conclusion

A careful review of the evidence suggests that Nigeria’s debt narrative requires greater nuance. President Bola Ahmed Tinubu cannot accurately be described as the largest borrower of Nigeria’s democratic era based on internationally comparable dollar-denominated metrics.

The sharp increase in naira debt figures since 2023 reflects, in significant part, the exchange-rate revaluation of inherited foreign-currency obligations rather than equivalent new borrowing. At the same time, Nigeria’s debt challenge should not be minimised. The country’s debt-service burden places substantial pressure on public finances and limits the government’s capacity to
invest in infrastructure and human development. The national conversation should therefore
move beyond simplistic headline figures toward a more constructive discussion about:

  • debt sustainability;
  • revenue mobilisation;
  • fiscal discipline;
  • refinancing strategies; and
  • ensuring that public borrowing supports long-term economic growth.

 

A fact-based assessment of Nigeria’s debt profile leads to one clear conclusion: the central challenge facing Nigeria today is not merely how much has been borrowed, but how inherited obligations, debt-service pressures, and limited revenues constrain the country’s development ambitions.
