The Central Bank of Nigeria (CBN) has introduced the Nigerian Overnight Financing Rate (NOFR) as part of efforts to improve transparency, efficiency, and credibility in the country’s money market. The initiative represents a major reform in Nigeria’s short-term interest rate framework and is expected to strengthen market confidence, liquidity management, and monetary policy transmission. Developed in collaboration with the Financial Markets Dealers Association (FMDA), the NOFR will serve as a transaction-based benchmark for overnight lending among financial institutions. Unlike previous benchmark systems that partly relied on estimates and quoted rates, the NOFR is derived strictly from actual overnight transactions within the interbank market.
Economist and educator, Yemisi Ayediran, said the reform is aimed at addressing weak transparency and unreliable benchmark pricing within Nigeria’s money market. According to her, previous short-term rates were often influenced by estimates and limited market information instead of real transactions, creating distortions in borrowing costs and weakening confidence in the financial system.She explained that the introduction of the NOFR would provide a benchmark that reflects the actual cost of overnight borrowing among financial institutions, thereby improving price discovery and transparency.
From an economic perspective, analysts believe the reform could improve efficiency in the allocation of short-term funds across the banking sector. Where benchmark rates fail to reflect actual market conditions, financial institutions and investors often struggle to accurately price risk and manage liquidity.
Ayediran noted that transaction-based benchmarks are generally more reliable because they reflect actual market activity rather than assumptions. She added that such systems are more difficult to manipulate and provide a clearer picture of liquidity conditions within the economy.
The reform is also expected to strengthen monetary policy transmission within the financial system. Analysts argue that the effectiveness of the CBN’s Monetary Policy Rate (MPR) depends largely on how efficiently policy signals are transmitted into interbank and commercial lending rates.
Because the NOFR reflects real overnight funding conditions, banks are expected to respond more accurately and quickly to policy adjustments by the apex bank. This could improve the transmission of policy decisions into lending rates, deposit rates, and borrowing costs across the economy.
Ayediran stated that the development could support inflation control, improve liquidity management, and enhance economic stabilisation efforts.To improve the reliability of the benchmark, the CBN adopted a volume-weighted trimmed mean methodology in calculating the rate. The approach removes unusually high or low transaction values that may distort the overall market average.
Financial consultant, Ochuko Johnson, explained that some overnight transactions may occur at abnormal rates due to temporary liquidity pressures, emergency funding needs, or operational issues. Excluding such outliers, he said, helps create a more stable and representative benchmark.
He added that the methodology aligns Nigeria with global benchmark reforms introduced after the LIBOR scandal, when regulators across major economies moved toward transaction-based reference rates to improve market credibility.
Market analysts believe the NOFR could also improve liquidity management within Nigerian banks. Treasury departments are expected to gain a clearer reference point for short-term borrowing costs, helping them manage reserve requirements and funding decisions more efficiently.
Johnson noted that a transparent benchmark could encourage stronger interbank lending activity by increasing confidence in market pricing. He also said the benchmark may improve the pricing of money market instruments, floating-rate loans, and future interest rate derivatives.
However, analysts warn that the reform may expose weaker banks to higher borrowing costs during periods of liquidity stress, particularly if overnight funding conditions tighten significantly.
Beyond the domestic market, the NOFR is expected to improve Nigeria’s attractiveness to foreign investors. International investors generally prefer markets with transparent pricing systems, credible benchmarks, and predictable policy transmission mechanisms.
Johnson observed that the reform aligns Nigeria more closely with international standards already adopted in advanced economies through benchmarks such as the Secured Overnight Financing Rate (SOFR) in the United States and the Sterling Overnight Index Average (SONIA) in the United Kingdom.
According to him, foreign investors in treasury bills, bonds, commercial papers, and money market funds would benefit from a more credible benchmark for pricing Nigerian financial assets.
Analysts further believe that the introduction of the NOFR could support the long-term development of derivatives markets, interest rate swaps, and other sophisticated financial instruments capable of deepening Nigeria’s financial system.Overall, the introduction of the Nigerian Overnight Financing Rate represents a significant institutional reform within Nigeria’s financial architecture. While the immediate impact may emerge gradually, the long-term objective remains the creation of a more transparent, efficient, and globally competitive money market.
