CBN’S 2025 MONETARY POLICY HIKE: LEGAL RISKS FOR LOAN AGREEMENTS, CONTRACTS, AND INVESTMENTS IN NIGERIA

Abstract

The Central Bank of Nigeria's (CBN) monetary policy decisions are commonly assessed from a macroeconomic perspective, with emphasis on inflation control, exchange rate stability and economic growth. However, their legal implications for private commercial relationships have received comparatively limited attention. The CBN's 2025 monetary policy tightening, characterized by sustained high interest rates, has significant implications for the negotiation, performance and enforcement of loan agreements, commercial contracts and investment transactions in Nigeria. Beyond increasing the cost of borrowing, it raises important legal questions concerning interest rate variation, contractual risk allocation, loan restructuring, regulatory compliance, investment structuring and dispute resolution.

This article examines the intersection between monetary policy and commercial law, arguing that while the Monetary Policy Rate (MPR) is primarily an economic instrument, its practical consequences are largely realizedthrough contractual and regulatory frameworks. Drawing on the Central Bank of Nigeria Act 2007, the Banks and Other Financial Institutions Act 2020, other relevant regulatory instruments and applicable legal principles, the article analyses the legal risks created by a high-interest-rate environment and their implications for borrowers, lenders, businesses and investors. It concludes that proactive legal drafting, robust regulatory compliance and effective contractual risk management are indispensable to preserving commercial certainty and mitigating disputes in an increasingly volatile economic landscape.

A. INTRODUCTION

Nigeria has, over the past two years, operated within one of its most restrictive monetary environments in recent history. Persistent inflationary pressures, exchange rate volatility, elevated food prices, and liquidity constraints prompted the Central Bank of Nigeria ("CBN") to adopt an aggressive monetary tightening strategy. Between February and November 2024, the Monetary Policy Committee ("MPC") increased the Monetary Policy Rate ("MPR") by a cumulative 875 basis points, from 18.75% to 27.50%, while maintaining a Cash Reserve Ratio ("CRR") of 50% for Deposit Money Banks and 16% for Merchant Banks. The MPC retained this restrictive stance throughout much of 2025, reflecting its commitment to restoring price stability despite its impact on credit markets and business financing.

The legal basis for these measures is rooted in the Central Bank of Nigeria Act 2007 (“CBN Act”), which mandates the CBN to ensure monetary and price stability. While the economic rationale for monetary tightening has been widely examined, its legal consequences have received comparatively less attention. Yet, sustained high interest rates increasingly influence the operation, performance, and enforcement of commercial agreements across the Nigerian economy.

For lenders and borrowers, higher financing costs have intensified debt servicing obligations, increased requests for restructuring, and heightened exposure to defaults and non-performing loans. Beyond banking relationships, long-term commercial contracts are under growing pressure from escalating financing costs, reduced liquidity, and counterparty distress, while investors are reassessing valuations, transaction structures, and capital deployment in response to changing market conditions. Consequently, monetary policy decisions once viewed primarily through an economic lens now carry significant implications for contractual certainty, risk allocation, and commercial transactions.

B. The Legal Framework Governing Monetary Policy in Nigeria

The Central Bank of Nigeria derives its monetary policy mandate principally from the Central Bank of Nigeria Act 2007.

Section 2 of the Act sets out the principal objects of the Bank, which include ensuring monetary and price stability, issuing legal tender currency in Nigeria, maintaining external reserves to safeguard the international value of the national currency, promoting a sound financial system and acting as banker and financial adviser to the Federal Government.

To achieve these objectives, the Act empowers the CBN to formulate and implement monetary and credit policies capable of promoting economic stability.

In furtherance of these objectives, Sections 11 and 12 of the CBN Act establish the Monetary Policy Committee, empowering it to formulate monetary and credit policy through instruments such as the Monetary Policy Rate. Acting pursuant to this mandate, the MPC increased the MPR by a cumulative 875 basis points between February and November 2024 to 27.50%, while maintaining the Cash Reserve Ratio ("CRR") at 50% for Deposit Money Banks and 16% for Merchant Banks as part of its broader strategy to curb inflation and tighten liquidity.

The CBN's monetary policy powers are reinforced by the Banks and Other Financial Institutions Act 2020 ("BOFIA"), which vests the Bank with regulatory and supervisory authority over licensed financial institutions and empowers it to issue regulations, guidelines, and prudential directives necessary to preserve financial system stability. Together, the CBN Act and BOFIA provide the statutory framework through which the CBN influences both the cost and availability of credit within the Nigerian economy.

Although the determination of the MPR and CRR constitutes an exercise of public regulatory power, its practical consequences are largely realized through private commercial relationships. Higher benchmark rates increase borrowing costs under floating-rate facilities, affect compliance with financial covenants, and reshape the commercial assumptions underpinning financing and investment transactions. Consequently, while the CBN's policy decisions are rooted in public law, their most significant legal implications arise within the sphere of private commercial law, where contractual risk allocation ultimately determines how the effects of monetary tightening are absorbed.

It is within this statutory framework that the contractual consequences of monetary tightening become most apparent, particularly in lending relationships where interest rate movement directly affects the parties’ rights and obligations.

Loan Agreements and Credit Facilities: Contractual Risks in a High Interest Rate Environment

Perhaps nowhere are the legal consequences of Nigeria's restrictive monetary policy more immediate than in lending relationships. The sustained increase in the Monetary Policy Rate ("MPR") has significantly increased borrowing costs, exposing both lenders and borrowers to heightened contractual risk. Facilities negotiated under lower interest rate assumptions are increasingly susceptible to payment and technical defaults, debt restructuring, and security enforcement.

The relationship between a bank and its customer remains fundamentally contractual, with the rights and obligations of the parties governed by the terms of the facility and security documents. This is more important in light of the Supreme Court’s affirmation in Nika Fishing Co. Ltd. v. Lavina Corporation (supra), that courts will not rewrite contracts voluntarily entered into by parties. Consequently, increased financing costs do not, without more, relieve borrowers of their contractual obligations.

To effectively hedge against these interest rate volatility, most commercial lending facilities incorporate floating or variable interest provisions, enabling lenders to reprice facilities in response to changing market conditions. Where such provisions exist, lenders generally possess contractual authority to adjust interest rates whenever market conditions change. However, this authority is not unlimited.

Under Nigerian contract law, contractual powers must be exercised in accordance with the express terms of the agreement. Where the contract requires prior notice before any variation takes effect, failure to provide such notice may amount to a breach of contract.

Similarly, if the agreement specifies the methodology for determining revised interest rates, the lender must strictly comply with that agreed formula. Any arbitrary departure from the contractual mechanism may expose the lender to legal challenge.

Notwithstanding the above, different legal considerations arise where parties have agreed on a fixed interest rate. A fixed-rate loan represents a contractual allocation of risk. The lender assumes the risk that market rates may increase during the tenure of the facility, while the borrower accepts the possibility that future market rates may decline. Unless the agreement expressly permits adjustment, a lender cannot lawfully increase the contractual interest rate merely because the MPR has risen. Doing so would amount to a unilateral variation of the contract, which Nigerian courts generally do not permit in the absence of contractual authority or mutual agreement. For this reason, lenders increasingly include carefully drafted review clauses in long-term financing arrangements to address significant market changes.

Indeed, one of the immediate consequences of higher interest rates is an increase in loan repayment obligations. As borrowing costs rise, borrowers may struggle to satisfy repayment obligations or financial covenants, triggering events of default, acceleration clauses, or the exercise of Material Adverse Change ("MAC") provisions where applicable. These pressures have increased the importance of consensual debt restructuring. Amendments to repayment schedules, covenant waivers, revised security packages, or additional credit support may offer commercially preferable alternatives to immediate enforcement, provided existing rights and security interests are carefully preserved.

Where restructuring proves unsuccessful, lenders may resort to enforcing guarantees and security interests in accordance with the facility documentation and applicable law. As reaffirmed in Union Bank of Nigeria Plc v. Ajabule (2011) 18 NWLR (Pt. 1278) 152, contractual security rights remain enforceable according to their terms. Against this backdrop, carefully drafted financing documentation and early restructuring efforts have become increasingly important in managing credit risk within a sustained high-interest-rate environment.

C. Commercial Contracts: Performance Risk in a High-Interest-Rate Environment

Beyond financing arrangements, the effects of sustained monetary tightening are increasingly evident in the performance of commercial contracts. Rising borrowing costs, reduced liquidity, and higher operating expenses have placed significant pressure on long-term procurement, construction, supply, and infrastructure agreements negotiated under markedly different economic conditions. While these developments may affect commercial viability, they do not, without more, relieve parties of their contractual obligations.

Nigerian law continues to uphold the principle of pacta sunt servanda, requiring contracts to be performed according to their terms. Accordingly, parties seeking to rely on force majeure or frustration in response to increased financing costs or inflation are unlikely to succeed unless the relevant contractual or legal requirements are satisfied. As the Supreme Court observed in Hilary Farms Ltd. v. M/V "Mahtra" (2007) 14 NWLR (Pt. 1054) 210, Judges are bound to enforce agreements exactly as written and cannot alter the terms of a voluntary contract.

Consequently, commercial counterparties are increasingly relying on negotiated solutions rather than legal excuses for non-performance. Price adjustment mechanisms, hardship clauses, and structured renegotiation provisions are becoming more prominent in long-term commercial agreements, particularly where prolonged economic volatility materially affects the commercial assumptions underpinning the transaction. Where renegotiation proves unsuccessful, disputes concerning contractual interpretation, delayed performance, or revised pricing are increasingly likely to be resolved through arbitration or other agreed dispute resolution mechanisms.

The current environment therefore reinforces the importance of careful contractual drafting. Agreements that clearly allocate economic risk and provide structured mechanisms for responding to changing market conditions are more likely to preserve commercial relationships and reduce the potential for costly disputes.

• Can Higher Interest Rates Amount to Force Majeureof Frustration of Contract?

One misconception that frequently arises during periods of economic instability is the assumption that increased borrowing costs automatically constitute a force majeure event. As a general rule, they do not. Force majeure clauses are contractual provisions that excuse or suspend performance where extraordinary events beyond the reasonable control of the parties prevent contractual performance. Common examples include natural disasters, war, terrorism, civil unrest, epidemics, government-imposed restrictions and similar unforeseen events. An increase in interest rates or borrowing costs rarely makes performance impossible. Instead, it merely makes performance more expensive.

Under Nigerian contract law, increased expense alone does not ordinarily excuse contractual performance unless the force majeure clause expressly includes changes in economic conditions, government monetary policies or exceptional financial disruptions within its scope.Businesses should therefore avoid assuming that the CBN's monetary policy decisions automatically entitle them to suspend contractual obligations.

Furthermore, closely related to force majeure is the common law doctrine of frustration. A contract is frustrated where, through no fault of either party, an unforeseen event fundamentally alters the nature of the contractual obligations such that performance becomes impossible or radically different from what the parties originally contemplated.

Nigerian courts apply this doctrine cautiously. A mere increase in operational expenses, financing costs or inflation does not ordinarily frustrate a contract. Businesses remain legally obligated to perform unless the change destroys the very foundation of the contractual relationship. For example, a company that borrowed funds to execute a supply contract cannot ordinarily avoid liability simply because interest rates have increased and financing has become more expensive.

The commercial risk of changing market conditions generally rests with the contracting parties unless the agreement expressly provides otherwise.

D. Investment Transactions: Capital Reallocation, Valuation Risks and Transactional Challenges

The CBN's restrictive monetary policy has significantly influenced the structuring of investment transactions across Nigeria's private capital markets. As higher yields on Nigerian Treasury Bills and Federal Government of Nigeria Bonds continue to attract institutional capital, private equity sponsors, venture capital investors, and corporate acquirers are increasingly adopting more conservative investment strategies. The legal implications are reflected less in the policy itself than in the evolving allocation of transactional risk.

One of the most immediate consequences has been increased pressure on transaction valuations. Higher financing costs have widened valuation gaps between buyers and sellers, prompting greater reliance on earn-out provisions, deferred consideration mechanisms, and other contingent pricing structures to allocate post-completion risk. These arrangements require careful drafting to minimize disputes over financial performance, accounting methodologies, and payment obligations.

Investment documentation has similarly become more robust. Investors are placing greater emphasis on Material Adverse Change clauses, enhanced governance rights, financial reporting obligations, and information covenants. Within private equity and venture capital structures, strict compliance with Limited Partnership Agreements ("LPAs"), particularly provisions governing capital calls, investor defaults, and dilution mechanisms, has assumed greater importance as liquidity pressures affect investors' ability to meet funding commitments.

The current environment has also expanded the scope of legal due diligence. In addition to conventional corporate and regulatory reviews, investors now closely assess existing debt obligations, covenant compliance, refinancing exposure, change-of-control provisions, and interest rate sensitivity to evaluate a target's financial resilience. Similar considerations have influenced project finance transactions, where rising borrowing costs have prompted covenant resets, revised repayment structures, and additional security requirements.

Accordingly, the sustained high-interest-rate environment is reshaping not only investment decisions but also the legal architecture of transactions, with greater emphasis on contractual flexibility, risk allocation, and transactional certainty.

E. Regulatory Compliance Obligations for Financial Institutions

Periods of monetary tightening require financial institutions to strengthen their legal and regulatory compliance frameworks.

The Banks and Other Financial Institutions Act, 2020 (BOFIA) grants the Central Bank of Nigeria extensive supervisory powers over banks and other financial institutions. Among other responsibilities, the CBN is empowered to issue prudential standards, supervise risk management practices and take regulatory measures necessary to promote the stability of the financial system.

Against this backdrop, lenders are expected to ensure that their lending practices remain legally compliant even as market conditions evolve.

In practical terms, financial institutions should:

• Review standard loan documentation to ensure that interest review clauses are clear, enforceable and consistent with current regulatory expectations;• Maintain transparent communication with customers regarding changes affecting loan obligations;• Conduct enhanced credit risk assessments before extending new facilities;• Properly document all loan restructuring arrangements;• Ensure that enforcement actions comply with contractual terms and applicable laws; and• Maintain effective internal governance systems capable of responding to increased credit risk during periods of economic stress.

Boards of directors and senior management also have an important governance responsibility to ensure that lending decisions remain prudent, commercially justifiable and consistent with regulatory expectations. Failure to maintain adequate risk management systems may expose institutions to regulatory intervention by the CBN.

F. Emerging Litigation and Dispute Resolution Risks

The prevailing high-interest-rate environment is likely to reshape the commercial dispute landscape as financing pressures increasingly translate into contractual defaults and restructuring challenges. While the CBN's restrictive monetary policy is not itself the subject of litigation, it has become a significant catalyst for disputes relating to debt recovery, security enforcement, corporate restructuring, valuation, and contractual performance.

Financial institutions are likely to experience an increase in loan recovery proceedings as borrowers struggle to meet repayment obligations under facilities affected by higher borrowing costs. Recovery actions will continue to be determined primarily by the terms of facility agreements and security documentation, with Nigerian courts consistently affirming that parties are bound by their contractual obligations.

Security enforcement disputes are also likely to become more frequent as lenders exercise powers of sale, appoint receivers, or realize collateral. In a weakened asset market, disagreements over valuation, sale procedures, and the exercise of mortgagees' powers may become increasingly common. Similarly, liquidity pressures are expected to drive more corporate restructurings under the Companies and Allied Matters Act 2020, giving rise to disputes concerning restructuring terms, creditor priorities, and amendments to existing financing arrangements.

Beyond traditional banking disputes, valuation disagreements are likely to feature more prominently in mergers and acquisitions, private equity investments, and project finance transactions, particularly where earn-out provisions, deferred consideration mechanisms, or refinancing obligations are affected by changing market conditions.

Given the commercial sensitivity of these disputes, arbitration and mediation are expected to remain the preferred means of resolution under the Arbitration and Mediation Act 2023, particularly where parties seek to preserve ongoing commercial relationships.

Ultimately, the current monetary environment is likely to increase not only the volume of commercial disputes but also the complexity of the legal issues they present, reinforcing the importance of careful contractual drafting, early restructuring efforts, and effective dispute resolution mechanisms.

G. Managing Legal Risks in a High Interest Rate Environment

The prevailing monetary environment reinforces the importance of proactive legal risk management. As elevated interest rates continue to affect financing and commercial transactions, lenders, borrowers, investors, and project sponsors should review existing contractual arrangements to identify areas of exposure and ensure that risk remains appropriately allocated.

For financial institutions, this includes periodic reviews of credit portfolios, with particular attention to variable interest provisions, financial covenants, security packages, guarantees, and events of default. New lending documentation should clearly define variation of interest, Material Adverse Change, acceleration, and enforcement provisions to minimize uncertainty and reduce the scope for future disputes.

Corporate borrowers should similarly assess existing financing arrangements for refinancing risks, covenant pressures, and maturity obligations. Where financial stress is anticipated, early engagement with lenders to negotiate restructuring, revised repayment schedules, or covenant waivers is generally preferable to allowing technical defaults to crystallize.

Commercial contracts should also be drafted with greater flexibility to accommodate sustained economic volatility. Depending on the nature of the transaction, parties may consider incorporating hardship provisions, price adjustment mechanisms, and structured renegotiation clauses to address significant changes in financing costs or market conditions. Investment and project finance documentation should likewise provide for appropriate valuation adjustment mechanisms, financial reporting obligations, and governance protections, while Limited Partnership Agreements should contain clear provisions governing capital calls and investor defaults.

Periodic contract audits and tiered dispute resolution clauses incorporating negotiation or mediation before formal proceedings may also assist in preserving commercial relationships and reducing dispute costs. In an environment where monetary policy continues to shape commercial outcomes, careful drafting, regular contractual review, and timely restructuring remain central to effective legal risk management.

H. Conclusion

The CBN's restrictive monetary policy has underscored the close relationship between public monetary policy and private commercial law. Although measures such as increases in the Monetary Policy Rate and the maintenance of a high Cash Reserve Ratio are directed at achieving macroeconomic stability, their practical effects are increasingly felt through the negotiation, performance, and enforcement of commercial transactions.

For lenders, borrowers, investors, and commercial counterparties, the current environment reinforces the importance of anticipating economic volatility when allocating contractual risk. Financing arrangements, investment documentation, and long-term commercial contracts should be structured with sufficient flexibility to accommodate changing market conditions while preserving commercial certainty.

Ultimately, elevated interest rates are no longer merely economic indicators; they have become material legal considerations that influence transaction structuring, contractual performance, and dispute risk. As Nigeria's financial landscape continues to evolve, organizations that embed robust contractual protections into their financing and commercial arrangements, will be better positioned to preserve value and navigate an increasingly uncertain commercial environment
