The Central Bank of Nigeria (CBN) has reopened access to its Open Market Operations (OMO) securities for individuals, companies and non-bank financial institutions, creating a new high-yield investment channel that could increase competition for funds flowing into Nigerian equities.
Under a circular issued on August 12, 2026, eligible investors can now participate in both the primary and secondary OMO markets through Deposit Money Banks. The move reverses a restriction introduced in 2019 and comes as investors show strong demand for short-term fixed-income instruments.
OMO Reopens to Wider Investor Base
OMO securities are used by the CBN to manage liquidity in the financial system. By selling OMO bills, the apex bank can absorb excess naira liquidity and influence financial conditions.
Unlike Treasury Bills, which represent Federal Government borrowing and help finance government expenditure, OMO securities are primarily monetary-policy instruments used by the CBN for liquidity management.
The distinction has become increasingly important as both instruments compete for investors seeking relatively low-risk, short-term returns.
OMO Offers Higher Yield Than Treasury Bills
Recent auction results highlight why the reopening could attract significant investor attention.
At the August 12 Treasury Bills auction, investors submitted approximately N4.4 trillion in bids against N700 billion offered by the government. The 91-day bill cleared at 16.30%, while the 182-day and 364-day instruments closed at 16.50% and 17.59%, respectively.
The following day, demand for OMO securities was even stronger.
Investors submitted N4.93 trillion in bids for N600 billion worth of OMO bills. The 103-day instrument recorded a 20.39% yield, while the 138-day bill cleared at 20.01%.
The CBN ultimately allotted about N2.60 trillion, significantly above its initial offer.
This means comparable OMO maturities were offering investors roughly 3.5 to 4 percentage points more than Treasury Bills, potentially making them particularly attractive to investors seeking short-term returns.
Will Increased Participation Push Yields Down?
The broader investor access could eventually put downward pressure on OMO yields, although analysts say the outcome will depend heavily on how aggressively the CBN uses the instruments to absorb liquidity.
Israel Adebomi, Head of Investment Banking at STL Capital & Advisory Limited, said stronger demand alone would not necessarily result in lower yields because the CBN could respond by increasing the volume of securities it supplies or accepts.
According to him, the key factors will be the CBN’s monetary and liquidity stance, the volume of securities supplied and investor demand.
Isaac Osaro, Head of Investment Research at First Securities Brokers Limited, similarly expects wider participation to create downward pressure on yields as more investors compete for OMO securities.
However, if the CBN continues accepting substantial volumes to sterilise excess liquidity, OMO rates could remain elevated.
NGX Faces Competition, But Not Across the Board
The reopening creates a potential alternative for investors who might otherwise allocate money to stocks, but analysts do not expect it to automatically trigger a widespread exit from equities.
The key issue will be the eventual level of OMO yields.
Osaro noted that fixed-income returns in the range of 15% to 18% could look attractive, but they may still fall short of the potential total returns available from strong equities over a longer period.
This means OMO is more likely to become another portfolio option rather than a direct replacement for stocks.
Strong Companies May Still Attract Capital
Higher fixed-income yields could nevertheless raise the standard investors apply when assessing equities.
Companies delivering strong earnings growth, attractive dividends and potential capital appreciation may continue to justify the additional risk associated with equities.
Conversely, stocks with weak earnings, limited dividend prospects or expensive valuations could face greater pressure if investors can obtain returns approaching 20% from relatively lower-risk OMO securities.
The development could therefore result in a more selective equity market rather than an across-the-board selloff.
Stock Selection Becomes More Important
The reopening of OMO to a broader investor base comes as Nigerian equities are already experiencing a period of profit-taking following a strong market rally.
The latest policy could add another layer of competition for domestic capital, particularly if OMO yields remain close to current levels.
For the NGX, the implication is less about investors abandoning equities entirely and more about how much additional return a stock can offer to justify its higher risk.
As OMO becomes accessible to a wider pool of investors, companies with solid fundamentals may remain attractive, while weaker or highly valued counters could find it increasingly difficult to compete for capital.
