What CBN’s overnight financing rates means for banks, small businesses

The Central Bank of Nigeria (CBN) on Monday in Abuja officially launched the Nigerian Overnight Financing Rate, a new transaction-based benchmark interest rate designed to strengthen transparency, improve monetary policy transmission and deepen the country’s financial markets.

Speaking at the launch at CBN headquarter, the Governor of the Central Bank of Nigeria, Mr Olayemi Cardoso, said the initiative formed part of the apex bank’s broader efforts  to build a more resilient, efficient and credible financial system.

The CBN in collaboration with the Financial Markets Dealers’ Association (FMDA), described the rate as Nigeria’s new overnight interbank benchmark.

About NOFR

With the unveiling of NOFR, it now moves the Nigerian financial markets toward a more transparent, transaction-based benchmark regime and creates the infrastructure for a deeper Nigerian money market.

The use of the NOFR by market participants requires deliberate action across operational, commercial, and legal functions. Subsequently, Institutions that move early to understand, implement, and properly document NOFR-linked transactions will be better positioned to manage risk and capture the emerging opportunities that come with a more mature benchmark environment.

NOFR is a transaction-based reference rate derived from actual overnight secured funding trades, specifically Naira transactions with a minimum size N5 billion between eligible financial institutions, reflecting current liquidity conditions in Nigeria’s interbank market.

The NOFR is administered and published by the CBN (as the benchmark administrator) daily at 10:00am on the business day following the fixing day.

Daily Trust observes that unlike the CBN’s Monetary Policy Rate (MPR) and other monetary policy instruments, the NOFR is a market-driven reference rate, not a policy-setting tool.

It captures the cost of secured overnight borrowing through Repurchased Agreements (REPO) transactions. The NOFR is intended to serve as a benchmark reference rate for a wide range of financial transactions, including loans and other Naira-denominated financial instruments.

The introduction of the NOFR is part of a broader effort by the CBN to enhance transparency, strengthen monetary policy transmission, deepen Nigeria’s financial markets, align with global benchmark reform trends, including the transition towards risk-free rates, and establish a more robust, data-driven reference rate, in Nigerian financial market just as it positions Nigeria alongside leading global benchmarks, such as SOFR (United States), SONIA (United Kingdom), €STR (Eurozone), and TONA (Japan), and complements African peer benchmarks, such as JIBAR (South Africa).

How it affects banks, debt markets

Checks by Daily Trust indicated that the NOFR will have implications for how financial products are structured, priced, and documented as it will affect the long-term depth and investor participation in Nigerian money markets.

First of all, government and corporate issuers of debt instruments may start to reference NOFR in floating-rate debt instruments and loan transactions. It will aid pricing transparency and aligns borrowing costs more closely with actual market liquidity conditions

In the same vein, banks and other lenders may begin referencing the NOFR in loan agreements, particularly for short-tenor and floating-rate facilities and in corporate, structured, and syndicated transactions where a credible overnight benchmark adds pricing rigour.

This is because the NOFR reflects actual market transactions rather than indicative submissions, it brings greater consistency and objectivity to rate-setting across institutions. We note, however, that the NOFR does not itself determine the all-in cost of a loan.

In addition to the NOFR, margins, fees, and other pricing components remain a function of credit risk, tenor, and the agreed commercial terms of each facility.

Similarly, the adoption of the NOFR has operational consequences for market participants, particularly financial institutions. With the coming of NOFR, institutions will need to review and update their internal systems, policies, and risk frameworks to accommodate the NOFR as an active benchmark. More broadly, treasury teams, legal and compliance functions, and other applicable functions will each need to develop a working understanding of   NOFR’s calculation methodology and how gaps or data-deficient fixing days are handled.

What it means for MSMEs

For Micro, Small and Medium Enterprises (MSMEs), NOFR will change how interest is set which means borrowing rates will now be based on actual market transactions rather than estimates.

Consequently, overdraft pricing will become more transparent, as NOFR is based on real transactions, as such bank will offer rates that more accurately reflect market conditions.

This reduces uncertainty and may mean businesses are charged less risk premium, making borrowing costs clearer. As a result, this lower-risk pricing can help reduce borrowing costs for SMEs.

Also, MSMEs who intend to borrow will have more clarity and predictability. Checks show that NOFR is based on real transactions, there is less rate volatility, making cash flow planning easier. More transparent rates can improve access to credit, as banks are more likely to lend when pricing is clear, and risk premiums are lower. However, worthy of note is that these changes may not be immediate as banks will need time to migrate their systems and loan pricing models to NOFR fully.

Why it matters – Cardoso

On why it matters, the CBN governor, Mr. Olayemi Cardoso said the benchmark was designed as a transaction-based overnight secured interbank financing rate that reflects the true cost of overnight funding in Nigeria’s money market.

“By anchoring the benchmark on observable transactions, NOFR enhances market integrity and credibility, reduces reliance on subjective estimates, minimises the risk of manipulation, and improves price discovery and transparency,” he stated.

He added that the new framework would strengthen confidence in Nigeria’s financial markets and support efforts to deepen market activities.

“The result of all of that is a deepening of our financial markets. Markets get deeper when they are trusted and when they are credible,” Cardoso said.

The CBN governor said the benchmark would serve as a transparent and reliable reference rate for treasury operations, liquidity management, pricing of financial contracts and securities, development of derivatives and structured products, and enhancement of risk management frameworks.

According to him, one of the most important benefits of the benchmark is its role in strengthening monetary policy transmission and supporting the central bank’s price stability mandate.

“The successful implementation of NOFR will reinforce domestic and international investor confidence, thereby contributing to sustainable economic growth,” he stated.

Speaking on behalf of Financial Markets Dealers’ Association (FMDA), Access Banks’ Group Head of Treasury, David Enilolobo, said benchmark rates influence pricing decisions affecting millions of customers and businesses daily, making the credibility of such rates critical to the financial system, noting that transaction-based benchmarks provide stronger market credibility than rates based on estimates or market opinions.

“Nigeria’s ambition to deepen its financial market and grow its standing in global capital flows cannot be realised without this kind of infrastructure,” he added.
