Nigeria’s debt service burden is rising at a pace that’s becoming hard to ignore, with fresh data showing a sharp escalation in repayments since 2023 and a growing squeeze on government finances.
Figures released by the Debt Management Office (DMO) reveal that total debt service climbed to N16.26 trillion in 2025—more than double the N7.79 trillion recorded in 2023. The spike marks a clear turning point in Nigeria’s fiscal trajectory, coinciding with the start of President Bola Ahmed Tinubu’s administration.
Quarterly data tells an even more striking story. Debt servicing costs have remained consistently high since the third quarter of 2023, peaking at a record N4.86 trillion in Q4 2025. That figure represents a 37.86% jump from the previous quarter and nearly 50% higher than the same period in 2024.
Before this shift, Nigeria’s debt service profile looked markedly different. Between Q3 2019 and Q2 2023, quarterly payments typically ranged from N400 billion to N900 billion, averaging about N753 billion. External debt obligations during that period were relatively contained, averaging just over N200 billion per quarter.
That pattern has since been replaced by a new reality. From Q3 2023 onward, quarterly debt service surged into a range of N2.46 trillion to N4.86 trillion, with an average of N3.47 trillion. External debt repayments alone have crossed the N1 trillion mark in nearly every quarter, hitting N2.57 trillion in Q4 2025.
The turning point came in Q3 2023, when external debt servicing spiked by more than 270% in a single quarter, driving a broader surge in total debt obligations. Since then, repayments have stayed above N2 trillion, steadily climbing past N3 trillion and now approaching N5 trillion per quarter.
External debt is now taking a dominant role. In Q4 2025, it accounted for 53% of total debt service, overtaking domestic obligations. While exchange rate movements have played a role—with the naira weakening significantly over the period—the latest spike was largely driven by increased repayment volumes rather than currency pressure alone.
The implications for Nigeria’s finances are severe. In 2024, the country generated N20.98 trillion in revenue but spent N12.74 trillion on debt servicing alone, meaning over 60% of earnings went into repayments. By 2025, the situation worsened, with nearly 70% of projected revenue expected to be used to service debt.
This leaves limited room for capital investment and economic development. With over a third of total government spending already tied to debt obligations, the ability to fund infrastructure, healthcare, and growth initiatives is increasingly constrained.
Beyond the numbers, the structure of Nigeria’s debt is also shifting. Greater reliance on external borrowing introduces new risks, particularly as repayments require foreign exchange, exposing the economy to global financial conditions and currency volatility.
The trend suggests this is no temporary spike. The consistency of elevated debt servicing since mid-2023 points to a structural change—one that could shape Nigeria’s economic outlook for years if not addressed.
