As Nigerian banks work to meet recapitalisation deadlines, a familiar concern has re-emerged: rising loan defaults amid expanding credit. Data from the Central Bank of Nigeria’s (CBN) 2025 macroeconomic outlook shows that the industry’s Non-Performing Loan (NPL) ratio has climbed to about 7 per cent, breaching the prudential limit of 5 per cent.
This deterioration is occurring despite improved credit availability and strong loan demand from households and businesses. On the surface, the trend appears contradictory. Beneath it, however, lies a combination of macroeconomic strain, abrupt policy shifts, and persistent corporate governance weaknesses that continue to erode asset quality.
Nigeria’s growing loan defaults cannot be blamed solely on borrower indiscipline. The economic environment has become increasingly hostile. Although recent data from the National Bureau of Statistics suggests inflation is easing and growth indicators are improving, living conditions for many Nigerians continue to worsen. Household purchasing power has declined, while businesses face rising operating costs.
Small and medium-sized enterprises are particularly exposed. Growth in this segment has been uneven and insufficient to counter rising expenses. Weak consumer demand across retail, manufacturing, and services has compressed revenues, while loan obligations remain fixed or increase. In such conditions, repayment stress is inevitable.
Tight monetary policy has deepened these challenges. The CBN’s aggressive interest rate hikes, aimed at restoring price and exchange-rate stability, have significantly increased borrowing costs. Variable-rate loans have become more expensive mid-tenure, pushing firms that borrowed under lower-rate assumptions into distress. Even otherwise viable businesses now struggle as interest expenses consume a growing share of income. Official surveys from late 2025 confirm rising defaults across secured, unsecured, and corporate loan categories.
Exchange-rate volatility has also taken a toll. The naira’s depreciation and foreign exchange reforms have sharply increased debt burdens for borrowers with dollar denominated loans but naira-based revenues.
Import-dependent firms have seen costs surge, while FX scarcity continues to disrupt production and trade. For many borrowers, the issue is not mismanagement but currency mismatch loans that were once sustainable have become unserviceable almost overnight.
These pressures are amplified by Nigeria’s difficult business environment. Chronic power shortages force companies to rely on costly alternatives, logistics bottlenecks and insecurity disrupt supply chains, and regulatory uncertainty complicates planning. Multiple taxation and compliance burdens further compress margins. Faced with survival choices, businesses often prioritise payrolls, energy, and raw materials over debt service.
Defaults, in many cases, are symptoms rather than causes.
However, macroeconomic factors alone do not fully explain the rise in NPLs. A critical and often underplayed contributor lies within the banking system itself weak corporate governance, particularly insider-related lending.
Corporate governance shapes how credit decisions are made and risks managed. Where oversight is weak, loan quality suffers. Nigeria’s banking history from the crises of the 1990s to the post-2009 clean-up shows that insider lending and boardroom abuses have been recurring problems.
Recent indications suggest these issues persist. Industry estimates and disclosures by former NDIC officials show that insiders and related parties have historically accounted for up to 40 per cent of bad loans in some banks, with a small number of institutions responsible for most insider-linked NPLs. While governance frameworks have improved, enforcement gaps remain.
Insider abuse typically involves loans granted to directors, executives, or connected entities with inadequate due diligence. Credit decisions are influenced by relationships rather than repayment capacity, collateral is overvalued, and covenants are weak. When distress appears, enforcement is delayed, restructurings are repeatedly extended, and recoveries are handled cautiously to avoid internal exposure.
The consequences are predictable. These loans default faster, are harder to recover, and crowd out credit to productive sectors. When insiders default without consequence, it weakens credit discipline and fuels moral hazard across the system.
Governance failures also undermine recovery efforts. Risk and audit committees are often ineffective, early warning signs are ignored, and legal remedies are pursued slowly. In an environment already burdened by judicial delays, this allows manageable problem loans to deteriorate into fully impaired assets.
External shocks from government policy have further strained bank balance sheets. Policy inconsistency makes cash-flow planning difficult for borrowers. Sudden tax changes, aggressive enforcement actions, and delays in government payments to contractors can quickly drain liquidity. Major reforms, such as fuel subsidy removal, have often been implemented without adequate transition buffers, transmitting immediate cost shocks across the economy.
Banks, heavily exposed to government-linked projects and regulated sectors, absorb these shocks directly. Exposure to oil and gas, power, and infrastructure remains particularly high. In 2024, nine banks’ exposure to the oil and gas sector rose to ₦15.6 trillion, a 94.4 per cent increase from ₦10.17 trillion in 2023. Unsurprisingly, NPL concentrations remain elevated in these sectors.
When the CBN ended pandemic-era regulatory forbearance in 2025, the true scale of loan stress became clearer. For years, banks were allowed to restructure troubled loans without classifying them as non-performing. While this preserved short-term stability, it masked underlying vulnerabilities. Once forbearance ended, many facilities crystallised as bad loans, pushing NPL ratios above regulatory limits.
The banking system remains broadly stable, supported by liquidity and capital buffers, with recapitalisation expected to add resilience. However, stability should not be mistaken for health. Rising NPLs erode profitability, tighten credit supply, and weaken investor confidence.
Addressing this challenge requires more than macroeconomic management. Governance reform must be treated as a systemic priority. Insider lending rules must be enforced rigorously, boards strengthened, and risk oversight empowered. At the same time, policy consistency, timely government payments, and credible transition frameworks would significantly reduce default risks.
Nigeria’s rising loan defaults are not just an economic indicator they are a governance signal. Without restoring discipline, transparency, and accountability, recapitalisation alone will only postpone, not prevent, the next reckoning.
