Nigeria’s exposure to the concessional lending window of the World Bank has climbed sharply, with fresh data showing that the country’s debt to the International Development Association (IDA) rose to $18.7bn as of December 31, 2025.
The figure represents a $1.9bn increase from $16.8bn recorded at the end of 2024, underscoring a sustained build-up in Nigeria’s multilateral obligations at a time of fiscal strain and constrained revenue performance.
Nigeria’s W’Bank IDA debt hits $18.7bn amid rising multilateral exposure
The latest financial statements released by IDA show that Nigeria is now the third-largest borrower within the institution’s global portfolio, trailing only Bangladesh and Pakistan.
The top 10 borrowers collectively account for roughly 60 per cent of IDA’s total exposure, highlighting the concentration of concessional financing among a handful of countries with significant development needs.
The rise in Nigeria’s W’Bank IDA debt hits $18.7bn at a period when the Federal Government continues to rely on external financing to fund budget deficits, infrastructure expansion and social sector interventions.
Analysts say the upward trend reflects ongoing project disbursements under Nigeria’s Country Partnership Frameworks, particularly in health, education, agriculture, and infrastructure.
While IDA loans are typically extended on highly concessional terms — long maturities, low or zero interest rates, and extended grace periods — the accumulation still adds to the country’s external debt stock. As of mid-2025, Nigeria’s total external debt stood at $46.98bn, according to official data from the Debt Management Office.
Of this, the World Bank Group accounted for over $19bn, making it Nigeria’s largest multilateral creditor.
This means that Nigeria’s W’Bank IDA debt hits $18.7bn within a broader external borrowing framework where the World Bank holds more than 40 per cent of total external obligations.
The scale of this exposure reinforces the institution’s central role in financing Nigeria’s development agenda.
IDA, which focuses on the world’s poorest and most vulnerable countries, has in recent years scaled up its operations through a hybrid financing model. By blending donor contributions with market borrowings, it has expanded its overall loan portfolio. As of December 31, 2025, IDA’s net loans outstanding rose to $226.4bn, up from $205.8bn a year earlier.
The increase in Nigeria’s W’Bank IDA debt hits $18.7bn against this backdrop of global expansion in concessional financing, particularly as developing economies grapple with inflationary pressures, currency volatility, and subdued growth.
However, economists caution that concessional terms alone do not eliminate fiscal risks. Dr. Muda Yusuf, an economist and CEO of the Centre for the Promotion of Private Enterprise, has previously argued that while deficit financing is a common fiscal tool globally, sustainability remains the critical test.
According to him, borrowing is not inherently problematic if funds are channelled into productive investments that enhance revenue generation and economic growth.
The concern arises when debt servicing begins to crowd out essential public spending or when new loans are contracted primarily to repay existing obligations.
With Nigeria’s W’Bank IDA debt hits $18.7bn, attention is increasingly turning to the country’s revenue performance.
Debt sustainability is largely a function of revenue-to-debt ratios rather than debt size alone. Nigeria’s relatively low revenue base, compared to peers, heightens vulnerability even under concessional borrowing arrangements.
Foreign exchange risk is another factor.
Since IDA loans are denominated in foreign currency, exchange rate depreciation can inflate repayment costs in naira terms. Analysts warn that excessive reliance on foreign loans could exert pressure on external reserves and complicate macroeconomic stability if not carefully managed.
In its financial disclosures, IDA emphasised the need to monitor country exposures in relation to repayment schedules, disbursement pipelines, and new commitments. The institution noted that assessing exposure requires evaluating both existing loan profiles and projected financing.
For Nigeria, the challenge lies in balancing development imperatives with prudent fiscal management. Infrastructure deficits, energy gaps, healthcare needs and education reforms demand substantial capital outlays.
Concessional financing remains attractive due to its affordability relative to commercial debt markets.
Yet as Nigeria’s W’Bank IDA debt hits $18.7bn, policymakers face mounting pressure to strengthen domestic revenue mobilisation, improve project efficiency, and ensure that borrowed funds translate into measurable economic returns.
Ultimately, the sustainability of Nigeria’s expanding multilateral debt portfolio will depend less on the headline figures and more on the country’s ability to grow its economy, diversify exports, and enhance fiscal discipline.
Without these structural adjustments, even concessional borrowing could evolve from a development catalyst into a long-term fiscal constraint.
