Nigeria has taken a decisive step to overhaul how short-term interest rates are determined, with the Central Bank of Nigeria introducing the Nigerian Overnight Financing Rate (NOFR), a transaction-based benchmark designed to bring greater transparency, credibility, and efficiency to the country’s money market.
The new rate, developed in collaboration with the Financial Markets Dealers Association, signals a shift away from indicative pricing toward a system anchored on actual interbank transactions. It practically reflects the cost of secured overnight funds exchanged between banks, offering a clearer and more reliable measure of liquidity conditions in the financial system.
In a statement signed by Hakama Sidi Ali, the CBN framed the move as part of a broader reform agenda aimed at aligning Nigeria’s financial architecture with global standards. The bank said the introduction of NOFR is expected to improve price discovery, promote consistent pricing of money market instruments, and reinforce the transmission of monetary policy decisions.

“It is expected to improve price discovery and transparency while promoting consistent pricing of money market instruments,” the statement said.
“It will enhance the effectiveness of monetary policy, support financial innovation, boost investor confidence, and strengthen risk management across the financial system.”
“It will support financial innovation, boost investor confidence, and improve risk management across the financial system.”
The central bank added that NOFR would serve as a credible benchmark for short-term lending activities, providing a foundation for pricing a wide range of financial instruments.
The reform places Nigeria within a global transition that gathered pace after the dismantling of LIBOR, when regulators moved toward transaction-based benchmarks to reduce manipulation risks and improve market integrity. In the United States, the Secured Overnight Financing Rate has become the primary reference rate for dollar markets. The United Kingdom relies on the Sterling Overnight Index Average, while the euro area uses the Euro Short-Term Rate, and Japan operates the Tokyo Overnight Average Rate. In Africa, South Africa’s Johannesburg Interbank Average Rate offers a regional parallel.
By adopting NOFR, the CBN is attempting to close a long-standing gap in Nigeria’s financial system, where benchmark rates have often been derived from quoted estimates rather than executed trades. That distinction has implications for market confidence. Transaction-based benchmarks are generally seen as more robust, particularly in volatile conditions when indicative rates can diverge from actual funding costs.
Nigeria’s interbank market has recently reflected tight liquidity conditions, with the overnight lending rate rising to 22.9% and the overnight Nigerian Interbank Offered Rate climbing to 22.84%. Across the curve, movements have been uneven. The three-month NIBOR increased by eight basis points, the six-month tenor eased by three basis points, while the one-month rate held steady. The Open Repo rate remained unchanged at 22.50%.
However, signals from the Treasury bill market point in a different direction. At its latest auction, the CBN raised N1.91 trillion at lower stop rates, with yields on longer-dated instruments, particularly the 364-day bill, declining sharply. This divergence between short-term funding costs and sovereign borrowing rates highlights inefficiencies in price formation across the market, a gap NOFR is intended to address.
From a policy perspective, the introduction of a credible overnight benchmark could materially improve transmission mechanisms. In Nigeria, changes to the policy rate have not always translated smoothly into lending and deposit rates, partly due to fragmentation in the money market. A reliable anchor like NOFR can help align short-term rates more closely with policy signals, strengthening the central bank’s ability to influence broader financial conditions.
There are also implications for market development. A transparent benchmark provides a foundation for pricing repo transactions, commercial paper, floating-rate notes, and derivatives. Over time, this could deepen secondary market activity and support financial innovation, areas where Nigeria’s market remains relatively underdeveloped.
For investors, particularly foreign portfolio managers, the reform addresses a key concern around pricing clarity. A benchmark grounded in observable transactions reduces uncertainty and improves comparability with other markets. This becomes more relevant in an environment shaped by elevated inflation, currency pressures, and shifting global capital flows.
The development of NOFR followed a structured engagement process within the financial system. The benchmark was adopted after a stakeholder meeting held on February 27, 2026, with regulatory approvals secured ahead of its official launch. The CBN will act as the benchmark administrator, with responsibility for governance, methodology, and regular publication.
Even so, the effectiveness of NOFR will depend on adoption and market depth. Banks and other financial institutions will need to integrate the rate into contracts, trading systems, and risk models. Transitioning away from existing benchmarks may require adjustments in pricing frameworks and operational processes. More critically, the underlying interbank market must sustain sufficient transaction volumes to ensure the rate remains representative.
However, financial experts note that the introduction of NOFR is, in essence, an infrastructure reform. It does not immediately lower borrowing costs or inject liquidity into the system. Its value lies in improving how prices are discovered and how policy signals are transmitted. But if implementation is consistent and adoption broad-based, it could reduce distortions in Nigeria’s financial markets and position the system on a more credible footing within the global financial industry.
