The Central Bank of Nigeria absorbed N1.945 trillion from the financial system through its May 29, 2026 Open Market Operations (OMO) auction as it moved to sterilise excess liquidity ahead of an expected N3.35 trillion inflow from maturing OMO and Treasury Bills securities.
The latest OMO auction results show that investors submitted bids worth N1.952 trillion against a combined offer size of N400 billion, underscoring strong demand for short-term government securities.
The auction comes just one week after the apex bank conducted a much larger OMO sale on May 21, where it allotted N3.47 trillion against subscriptions of N3.48 trillion, bringing total OMO liquidity mop-ups within eight days to N5.42 trillion.
The latest auction details highlight sustained demand for short-term government securities, even as the CBN continues its aggressive liquidity management operations to stabilise inflationary pressures and support exchange rate stability.
The May 29 auction comprised two OMO instruments, with the 102-day and 11-day bills attracting strong investor participation across maturities.
Total subscription reached N1.952 trillion against an offer of N400 billion, while total allotment stood at N1.945 trillion, reflecting the overwhelming demand from market participants.
For the 102-day bill, investors subscribed N1.727 trillion against an offer of N200 billion, and the CBN allotted N1.725 trillion at a stop rate of 20.37 percent.
The 11-day bill recorded subscriptions of N225 billion against N200 billion on offer, with N220 billion allotted at a stop rate of 21.80 percent.
The auction did not involve repayments, indicating a pure liquidity absorption exercise by the apex bank.
Although the May 29 auction was smaller than the May 21 exercise, investor appetite remained strong across tenors.
Earlier, the May 21 auction saw the CBN offer N700 billion across three tenors but receive subscriptions of N3.477 trillion, with total allotments reaching N3.47 trillion.

Combined, the two auctions absorbed N5.42 trillion within just over a week, reinforcing the Central Bank of Nigeria commitment to tightening liquidity conditions amid inflation and foreign exchange management efforts.
Analysts at Cowry Asset Management Limited expect large maturities of about N2.72 trillion in OMO bills and N631.46 billion in Treasury Bills in the first week of June.
In its weekly market outlook, Cowry Asset Management Limited projected total liquidity inflows of N3.35 trillion for the week, driven by maturing instruments across the short-term segment.
The analysts said the large maturity profile could sustain strong demand at upcoming fixed income auctions if the apex bank maintains its liquidity management strategy.
The sustained mop-up of liquidity reflects the CBN’s broader monetary policy tightening stance aimed at managing inflation expectations and reducing excess cash in the banking system, which has remained elevated due to maturing instruments and fiscal-related inflows.
Market analysts say such operations help to anchor short-term interest rates and improve transmission of monetary policy decisions across the financial system.
However, they also note that aggressive liquidity sterilisation may keep funding costs elevated for banks and corporate borrowers in the near term.
Despite this, investor appetite for OMO bills remains strong due to attractive yields compared to other short-term investment alternatives in the domestic market.
According to Cowry Asset Management Limited, the large maturity wave expected in early June could temporarily boost system liquidity even as the CBN continues its sterilisation efforts.
Nairametrics reports that sustained participation in OMO auctions reflects growing investor preference for risk-free government instruments amid uncertain macroeconomic conditions and persistent inflationary pressures.
The interplay between large maturities and aggressive mop-up operations is expected to shape liquidity conditions in the Nigerian financial system over the coming weeks, with possible implications for short-term interest rates and currency stability.
Financial system operators are expected to closely monitor upcoming Treasury Bill auctions and CBN open market interventions as liquidity dynamics evolve, particularly as seasonal fiscal flows, debt maturities and monetary policy adjustments continue to interact in shaping market sentiment across fixed income and foreign exchange segments with heightened vigilance from investors and policymakers alike as market conditions remain fluid and data dependent environment.
