CBN Opens OMO Market to Wider Investors, Eases Bank Funding Rules

The Central Bank of Nigeria has announced a set of financial-market reforms that broaden access to its Open Market Operations, ease bank funding rules, and restart tenored repurchase agreements. The changes are contained in a circular to banks and are aimed at deepening domestic financial markets and improving monetary policy transmission.

OMO investor base expanded

Under the new framework, individuals, corporates and non-bank financial institutions can now participate in OMO securities through Deposit Money Banks. The segment was previously dominated by banks and other financial market participants. Analysts say the expanded base should increase demand for short-dated securities, deepen market activity and improve price discovery.

The CBN retains full discretion over the volume, tenor and frequency of OMO issuances. That means the regulator remains a major determinant of liquidity and yield outcomes even as market demand influences pricing.

Impact on yields and investors

Wider participation could put pressure on yields over time. With more investors competing for short-dated instruments, demand may rise. If supply does not keep pace, yields could compress. That would reduce returns on Treasury bills and OMO instruments for investors who have enjoyed elevated naira yields.

For banks, sustained yield compression could moderate income from securities portfolios. Treasury operations have traditionally been a key income source for Nigerian banks. For foreign portfolio investors, stronger domestic demand could reduce reliance on offshore buyers, but significantly lower yields would weaken the carry advantage of naira assets. Attractiveness to foreign investors depends on inflation expectations, exchange rate stability and the ability to repatriate proceeds.

Discount window and standing lending facility

The CBN also relaxed restrictions on banks' access to the discount window and Standing Lending Facility. Banks that access the window can now continue participating in the FX market and government securities auctions. This reduces the opportunity cost of seeking central bank liquidity. A bank with a temporary liquidity mismatch no longer has to withdraw from other key markets just because it approached the CBN for funding.

One safeguard remains: banks cannot participate in OMO auctions on the same day they access the discount window. That restriction is meant to limit regulatory arbitrage and prevent banks from using central bank liquidity to exploit OMO investment opportunities.

Tenored repos resume

The third reform is the resumption of tenored repurchase agreement operations with maturities ranging from four to 90 days. This gives banks a more predictable funding channel and reduces reliance on overnight and very short-term funding. It should improve asset-liability management by allowing funding positions to be matched more efficiently with asset maturities. For the CBN, tenored repos provide another tool for injecting or withdrawing liquidity in a targeted manner, which should help reduce excessive volatility in money-market rates.

For the naira and Nigerian businesses, the reforms signal a push for a deeper, more accessible fixed-income market. If domestic demand for OMO instruments rises, it could support monetary policy transmission and reduce dependence on foreign capital. But the direction of yields will ultimately depend on how the CBN adjusts issuance volumes in response to the wider investor base.
