Draft OTC fixed income framework sparks debate over future of broker role in Nigeria

A draft framework circulating within Nigeria’s fixed income market suggests the Central Bank of Nigeria (CBN) and the Financial Markets Dealers Association (FMDA) may be considering significant changes to the operating model of over-the-counter (OTC) fixed income brokers.

The draft document, seen by Nairametrics and shared among market participants, proposes a stricter agency-based brokerage structure that would limit brokers from taking proprietary positions, acting as principal in transactions, or engaging in securities borrowing and lending activities.

However, the framework has not been formally issued by the CBN or FMDA, and market participants say discussions are ongoing regarding its potential implications for competition, pricing transparency, and market structure.

A major insider at the CBN opine the document is not official, further denying that it is under any form of consideration. The central bank typically publishes an official draft exposure for documents seeking wider inputs before they are made official.

What they are saying  

Under the draft framework seen by Nairametrics, brokers would be restricted to acting solely as intermediaries between clients and Authorized Dealer Banks (ADBs), effectively removing their ability to take proprietary positions, act as principal in transactions, or engage in securities borrowing and lending activities.

The proposed rules introduce a sharper distinction between brokerage activities and risk-taking functions in the OTC fixed income market.

• If implemented substantially in their current form, they would transform brokers into pure agency intermediaries while shifting pricing and balance-sheet risk to dealer banks.
• Fixed income brokers must hold a valid SEC licence and all OTC fixed income trades would be intermediated through an Authorized Dealer Bank.
• Brokers would be prohibited from proprietary trading, inventory holding, securities borrowing and lending, and acting as principal in any transaction.
• Pricing responsibility would rest solely with Authorized Dealer Banks, while settlement funds would move through clients’ bank accounts rather than broker accounts.

Brokers would be required to maintain electronic audit trails, while annual compliance certifications signed by senior officers would be submitted to the Central Bank of Nigeria.

The draft framework also provides the CBN with supervisory and inspection rights over brokerage firms operating within the OTC fixed income market.

While some market operators view the proposals as aligning Nigeria with international regulatory trends aimed at reducing conflicts of interest in opaque OTC markets, others argue that the framework raises important questions about pricing transparency, competition, and market structure.

Some market participants believe the framework could materially alter the economics of fixed income broking in Nigeria.

• Historically, brokerage revenues in certain segments of the OTC market have been generated not only from commissions but also from activities such as spread capture, inventory positioning, and principal facilitation around client transactions.
• Under the proposed structure, those activities would largely disappear, leaving commission income as the primary source of revenue.
• Firms may need to strengthen governance processes, implement electronic order-capture systems, maintain detailed audit trails, and provide annual regulatory attestations.
• The proposals could increase the strategic importance of relationships between brokers and Authorized Dealer Banks, which would become the primary institutions responsible for pricing and risk warehousing.

Brokers with access to a broader network of dealer banks may be better positioned to secure competitive execution for clients than firms with more limited relationships.

Industry participants say the proposals could therefore reshape both the revenue model and operating structure of many brokerage firms.

Analyst views  

Supporters of the framework argue that the proposals reflect regulatory approaches adopted in several advanced financial markets following years of misconduct scandals involving benchmark manipulation, foreign exchange rigging, and opaque pricing practices.

• They contend that conflicts of interest are more difficult to monitor in OTC fixed income markets than in exchange-traded equity markets.
• Proponents say separating brokerage functions from dealer activities can reduce potential conflicts between brokers and clients.
• They argue that agency-only structures allow brokers to focus on client matching while dealer institutions assume pricing and balance-sheet risk.

Critics, however, maintain that restricting brokers alone does not address broader concerns around market transparency and price discovery.

• Some market operators believe complementary reforms may be required to ensure that dealer-bank pricing remains competitive and transparent.
• The debate among market participants is therefore centred not only on broker conduct but also on the broader structure of Nigeria’s OTC fixed income market.

What you should know  

In November last year, Nairametrics had reported that CBN’s bid to take control of the nation’s fixed-income market triggered regulatory controversies in Nigeria’s financial sector. The latest move on the OTC fixed income market is part of the radical push by CBN towards establishing a unified regulatory framework for Nigeria’s fixed income market since last year, 2025.  

At this stage, market participants say discussions around the framework remain ongoing, with many seeking further clarification on the scope, intent, and implementation timeline of the proposals.

• Some stakeholders have called for a consolidated post-trade reporting system for OTC fixed income transactions.
• Others advocate mandatory delayed reporting of bond trades and wider adoption of multi-dealer electronic trading platforms.
• Market participants have also suggested introducing a matched-principal exemption similar to frameworks used in some international markets.
• Some operators want agency brokers to retain participation in repo-related intermediation activities.

Should the proposals eventually be adopted in substantially their current form, they could represent one of the most significant changes to Nigeria’s OTC fixed income market architecture in recent years.
