Nigeria’s first Treasury-bill auction following the Central Bank of Nigeria’s (CBN) 350-basis-point reduction in the Monetary Policy Rate (MPR) has shifted attention from the size of the rate cut to a more consequential question: can demand for naira-denominated assets remain strong as short-term yields decline?
The CBN lowered the MPR from 26.5% to 23% at its September 21–22 Monetary Policy Committee meeting, while also recalibrating the Standing Facilities Corridor to +50/-300 basis points around the MPR.
The central bank described the decision as a monetary-policy reset aimed at improving policy transmission and bringing the benchmark rate closer to prevailing market conditions.
The first Treasury-bill auction after the decision now offers an early indication of how investors are responding to the new rate environment.
Treasury-Bill Yields Fall Across All Tenors
The repricing was evident across the three Treasury-bill maturities offered at the auction.
The 91-day stop rate declined to 15.50%, from 16.30% at the previous auction, while the 182-day bill fell to 15.80%, from 16.50%.
The biggest decline was recorded at the long end of the curve. The 364-day Treasury bill cleared at 15.89%, compared with 16.62% previously, representing a 73-basis-point decline.
However, demand was sharply uneven across the maturities.
The 91-day bill attracted N54.93 billion in subscriptions against N100 billion offered, while the 182-day instrument received N82.23 billion against the same N100 billion offer.
The 364-day bill, by contrast, attracted approximately N4.09 trillion in subscriptions against N400 billion offered. That represented about 97% of total subscriptions recorded at the auction.
The concentration of demand at the one-year tenor is significant. It could indicate that investors remain willing to hold Nigerian fixed-income assets despite lower yields. It could also suggest that investors are seeking to lock in prevailing returns ahead of potentially further monetary easing.
The auction data, however, do not distinguish between foreign and domestic participation. Strong banking-system liquidity also provides an important alternative explanation for the strength of demand.
The Market’s Carry Advantage Is Beginning to Narrow
According to David Precious, Senior Market Analyst at EBC Financial Group, the central issue for investors is increasingly whether Nigeria can retain capital as the yield advantage begins to diminish.
“The key issue is no longer whether high yields can attract money into Nigeria. They already have. The next test is whether demand remains resilient as the yield advantage narrows, because that would help show whether investors are responding increasingly to stronger external buffers and macroeconomic stability, or whether carry is still doing most of the work.”
For investors holding naira assets, the nominal Treasury-bill yield is only one component of the overall return equation.
Exchange-rate movements, inflation, market liquidity and the ability to exit or reinvest funds can all influence realised returns. Consequently, lower domestic yields do not necessarily translate automatically into capital outflows, but they reduce the cushion available to investors should other risks increase.
Higher Dollar Returns Add Another Layer of Pressure
The changing global interest-rate environment is also becoming increasingly relevant to Nigerian assets.
The source notes that on September 16, the US Federal Reserve raised its policy rate by 25 basis points to a target range of 3.75% to 4.00%, its first increase since 2023.
That move increases the return available on dollar-denominated assets at the same time that Nigerian short-term yields are declining.
For international investors, the resulting narrower yield differential makes the stability of the naira and confidence in Nigeria’s external position more important.
Precious said investors therefore need to look beyond Nigerian yields in isolation.
“The gap matters because investors do not assess Nigerian yields in isolation. If returns on lower-risk dollar assets rise while naira yields fall, currency stability and confidence in Nigeria’s external position become more important parts of the decision.”
He added that the market would need to distinguish between demand driven by improving economic fundamentals and demand primarily motivated by the opportunity to lock in high yields.
Nigeria Moves From Attracting Capital to Retaining Confidence
The latest auction also highlights a broader transition in Nigeria’s fixed-income market.
The initial phase of Nigeria’s monetary and foreign-exchange adjustment was heavily influenced by the need to restore investor confidence, improve foreign-exchange market functioning and maintain sufficiently attractive local-currency returns.
With the CBN now moving into a more substantial easing phase, the next question is whether investor confidence can remain durable when the compensation for holding naira assets declines.
The issue has also featured in EBC’s earlier analysis of Nigeria’s foreign-exchange reserves. Stronger reserves can improve the country’s external buffer, but portfolio capital can remain sensitive to changes in the risk-return equation.
That makes the distinction between attracting capital and retaining capital increasingly important as monetary conditions change.
OMO Demand Shows Strong Appetite, But Liquidity Matters
Recent Open Market Operations (OMO) activity provides another indicator of fixed-income demand, although it does not provide a definitive answer about foreign investor participation.
At the September 24 OMO auction, the CBN offered N1 trillion across three maturities and received approximately N6.1 trillion in subscriptions, with N2.3 trillion allotted.
The 152-day bill cleared at 17.29%, while the 180-day instrument cleared at 16.99%.
But the scale of subscriptions needs to be considered alongside liquidity conditions in the banking system.
Banking-system liquidity stood at approximately N5.98 trillion in the week ended September 25, while another N2.43 trillion in OMO maturities was expected to return to the system.
This means strong demand for government securities may partly reflect domestic liquidity seeking short-duration fixed-income instruments rather than a fresh surge in foreign portfolio investment.
Naira Stability Becomes More Important as Yields Decline
As the carry advantage narrows, the performance of the naira becomes increasingly important to investors.
The naira closed Friday at N1,329.51 per dollar in the official market, only marginally weaker than the previous session.
For holders of local-currency securities, exchange-rate stability can be crucial. A significant depreciation of the naira can quickly offset income earned from a Treasury bill, particularly when the underlying yield advantage is already narrowing.
This creates a more complex equation for investors.
If inflation continues to moderate, foreign-exchange liquidity remains functional and Nigeria’s external buffers strengthen, investors may continue to accept lower nominal yields.
If those conditions deteriorate, however, the smaller carry cushion could become more consequential.
That is why the CBN’s 350-basis-point policy reset cannot be assessed solely by the headline reduction in the MPR. Its broader impact will depend on how yields, liquidity, inflation, exchange rates and investor confidence interact over the months ahead.
What Investors Will Watch Next
The next Treasury-bill and OMO auctions will provide additional evidence of how the market is adapting to the new monetary-policy environment.
Investors will be watching whether demand remains concentrated in longer-duration Treasury bills and whether market participants continue accepting progressively lower yields.
The composition of portfolio flows will also matter. The latest auction results do not reveal how much of the subscription came from foreign investors, making it difficult to interpret the headline demand as a direct measure of international appetite for Nigerian assets.
Liquidity conditions will remain another important variable, particularly as substantial OMO maturities inject additional funds into the banking system.
Ultimately, Nigeria’s evolving fixed-income story is moving beyond the question of whether high yields can attract investors. The more difficult test is whether stronger macroeconomic fundamentals, external buffers, currency stability and confidence in policy direction can sustain demand when investors are being paid less to hold naira assets.
That transition—from attracting capital through exceptional yields to retaining confidence through stronger fundamentals—could become one of the defining tests of Nigeria’s next phase of monetary-policy normalisation.
