Introduction

On April 17, 2026, the Central Bank of Nigeria (CBN) announced the introduction of the Nigerian Overnight Financing Rate (NOFR) in collaboration with the Financial Markets Dealers Association (FMDA). The NOFR is a daily benchmark designed to reflect the actual cost of short-term borrowing between banks, based on real market transactions. According to the CBN, the introduction of the NOFR is aimed at enhancing transparency, strengthening monetary policy transmission, and deepening Nigeria’s money market.

In this newsletter, we highlight the rationale and framework of the NOFR, as well as its implications for the market.

What is the Rationale behind the NOFR?

Nigeria’s short-term interest rates have traditionally been guided by the Monetary Policy Rate (MPR) and interbank indicators such as the Open Buy Back (OBB) and Overnight (OVN) rates, which are meant to reflect the cost of overnight borrowing between banks.

However, these indicators do not always reflect actual transactions, as they may be influenced by estimates, limited trading activity, or inconsistent reporting. As a result, they may not accurately capture the true cost of short-term funding.

The Nigerian Overnight Financing Rate (NOFR) was introduced to address this gap by replacing indicative pricing with a benchmark based on actual transactions, thereby improving reliability and market confidence.

What is the Framework of the NOFR?

The NOFR is an average interest rate that reflects the actual cost of overnight lending between banks in naira, where the loans are secured by collateral, and based on real market transactions. The rate is calculated by giving more weight to larger transactions and removing unusually high or low rates (the higher 10% and the lower 10% percent volumes are excluded from the calculation), so that the final figure reflects normal market conditions and provides a more accurate picture of how banks actually price short-term funding.

The transactions used to calculate the NOFR must meet the following conditions:

  1. they must be carried out on the specific day the rate is being calculated (the fixing day);
  2. they must be reported by approved banks;
  3. Each transaction must be at least ₦5 billion, so that only significant market activity is included.

The rate is published daily at 10:00 a.m. for the preceding business day. Where there is insufficient qualifying transaction data, the previous day’s rate is retained and published to ensure continuity and stability. The CBN is responsible for the governance and regular publication of the NOFR. The rate can be accessed on the CBN website.

 

What are the Key Market Implications?

Some key market implications of the introduction of the NOFR are set out below:

  1. Corporate Borrowers: While the NOFR may not immediately reduce borrowing costs, it provides a clear and transparent base rate for floating-rate loans. This makes loan pricing more consistent and easier to compare. Borrowers may seek to review existing loan agreements, especially floating-rate clauses, as pricing will gradually shift to NOFR-based benchmarks, making interest costs more responsive to overall market conditions.
  2. Banks and Financial Institutions: In view of the improved accuracy in pricing short-term loans, banks will have a clearer view of funding costs, enabling more effective day-to-day liquidity management.
  3. Investors: The greater transparency and reliability of the NOFR may make it easier to price and value instruments such as treasury bills and bonds. This is expected to improve pricing consistency across the market and give both local and foreign investors greater confidence in expected returns.
  4. Legal/Contractual Considerations: The introduction of the NOFR means that existing financial agreements referencing older interbank rates or bank-specific pricing may need to be reviewed and updated to reflect the new benchmark. Going forward, new agreements are likely to adopt NOFR as the base rate, with an added margin. This makes it important to include clear provisions on benchmark use and replacement in new agreements.

Conclusion

The introduction of the NOFR marks a significant shift in how interest rates are determined in Nigeria and aligns the country with global benchmarks best practices such as the Secured Overnight Financing Rate (SOFR) in the United States and the Sterling Overnight Index Average (SONIA) in the United Kingdom. While the CBN expects the NOFR to enhance transparency, strengthen monetary policy transmission, and deepen Nigeria’s money market, its impact will ultimately depend on adoption and effective administration.

New CBN Measures on Diaspora Remittances: What They Mean for Market Participants

Introduction

On March 24, 2026, the Central Bank of Nigeria (CBN) issued a circular on Measures to Further Deepen Diaspora Remittances and Compliance (the “Circular”). The Circular, which is effective from May 1, 2026, builds on the CBN’s revised guidelines for international money transfer services in Nigeria, and is aimed at enhancing  diaspora remittances, strengthening transparency, traceability, and effective monitoring of all remittance related transactions.

In this newsletter, we highlight the measures introduced by the CBN and assess their practical implications for participants.

What Are the New Measures?

The following measures have been prescribed by the CBN.

  1. Designated Naira Settlement Accounts: All transactions related to International Money Transfer Operators’ (IMTO) operations, including payments to beneficiaries and any settlements, must be processed through designated settlement accounts held with authorised dealer banks (ADBs or Banks). IMTOs may either open new accounts or use existing ones for this purpose and can maintain multiple naira settlement accounts based on their business needs. However, they are required to regularly provide the CBN with an updated list of these designated accounts through the Director of the Trade and Exchange Department.
  2. Account Funding Restrictions: The circular makes it clear that these settlement accounts can only receive money from remittances or foreign exchange transactions carried out by the IMTOs or their agents through authorized participants in the Nigerian Foreign Exchange Market (NFEM). This means that no other funds are allowed to be deposited into these accounts.
  3. Authorised Transfers to Other Market Participants and BDCs: To improve the flow of foreign exchange and support fair pricing, ADBs are permitted to process foreign currency transfers from IMTO settlement accounts to other ADBs and approved market participants, including licensed Bureau de Change (BDC) operators.
  4. Real-Time FX Pricing: IMTOs must set their remittance rates to reflect current market prices from Bloomberg’s BMatch platform rather than being set independently. By doing this, the CBN aims to ensure more accurate pricing, reduce information gaps between banks and IMTOs, and encourage greater use of the official FX market.
  5. Compliance and Record Keeping: In addition to complying with the above measures, all IMTOs (and ADBs) must strictly comply with anti‐money laundering and counter-terrorism financing rules. Detailed records of all remittance transactions (origins, amounts, beneficiaries, conversions, etc.) must also be kept for regulatory review and audit purposes.

 

What Are the Practical Implications?

The new measures may require certain operational changes. We have set out below, some key implications and action points for IMTOs, banks, BDCs and other stakeholders:

  1. IMTOs (Money Transfer Operators):

    In view of the above regulatory measures, IMTOs may require system upgrades and staff training and must also strengthen record-keeping and AML/KYC processes, maintaining detailed transaction logs for regulatory review.

  2. ADBs (Commercial Banks):

    ADBs should prepare for increased demand from IMTOs to open and manage multiple naira settlement accounts and streamline onboarding processes accordingly. Banks will also need to closely monitor these accounts to ensure they are used solely for remittance flows and comply with FX funding requirements, while supporting IMTOs in meeting AML/CFT obligations.

  3. BDCs:

    Since ADBs are permitted to process foreign currency transfers from IMTO settlement accounts, BDCs may engage ADBs and their IMTO partners to access this FX liquidity.

  4. General Market Effects:

    In general, the measures are expected to improve transparency by channeling remittance flows through the formal banking system, giving the CBN greater visibility into FX inflows. In the medium term, it is expected that this will reduce reliance on informal markets, support better rate alignment, and contribute to improved liquidity and stability in the FX market.

Conclusion

The CBN’s new measures on diaspora remittances are part of a series of significant steps toward formalising diaspora remittance flows and improving transparency in Nigeria’s foreign exchange market. By mandating designated settlement accounts, real-time pricing, and stricter compliance standards, the framework is expected to enhance liquidity, strengthen regulatory oversight, and reduce reliance on informal channels. While stakeholders will need to adjust their operations to meet the new requirements, the CBN expects that the reforms should, over time, support better price discovery and contribute to greater stability of the naira.
