Nigerian banks face pressure, has they brace up for tighter operating conditions after the Central Bank of Nigeria (CBN) introduced a 75 per cent Cash Reserve Ratio (CRR) on non-Treasury Single Account (TSA) deposits, a move designed to curb excess liquidity in the financial system.
The new directive, announced by CBN Governor Olayemi Cardoso following the Monetary Policy Committee’s (MPC) two-day meeting in Abuja, is expected to significantly reshape how commercial banks manage state and local government funds.
According to Cardoso, the policy shift comes despite Nigeria’s gradual inflation deceleration, with the apex bank concerned about persistent liquidity surpluses.
These surpluses, largely driven by revenue distributions from the Federation Account Allocation Committee (FAAC), have been fueling foreign exchange volatility and sustaining inflationary pressure.
Why the CBN is clamping down
TSA deposits represent the Federal Government’s consolidated funds parked directly with the CBN.
In contrast, non-TSA deposits—largely comprising state and local government revenues—are traditionally kept with deposit money banks.
After FAAC disbursements, these deposits tend to inflate liquidity across the sector, often sparking higher demand for foreign exchange.
Financial analysts at Afrinvest explained that banks face pressure as CBN tightens liquidity rules because these non-TSA government funds have historically provided a reliable stream of cheap deposits for commercial lenders.
“Episodes of naira depreciation often coincided with FAAC inflows. By sterilising 75 per cent of such deposits, the CBN is forcing banks to seek more private-sector funding,” Afrinvest noted in its latest report.
Impact on banks and private sector lending
For lenders with heavy exposure to government deposits, the policy poses a direct threat to margins.
The sterilisation means banks will lose access to a significant portion of previously cheap liquidity, compelling them to double down on mobilising retail and corporate deposits.
Industry experts warn this may also lead to stiffer competition for private-sector funds, potentially raising borrowing costs.
Tilewa Adebajo, CEO of CFG Advisory, said the policy reflects the CBN’s determination to maintain inflation control.
“I’m pleased that the MPC raised the CRR on non-TSA deposits to 75 per cent. Excess liquidity has been driving core inflation, particularly through fiscal spending. By mopping up these balances, the CBN is reinforcing its inflation fight and signalling fiscal discipline,” he told our correspondent.
Adebajo, however, added that Nigerians may not feel the full benefits of inflation moderation until headline inflation drops closer to 12 per cent. “If we can get to that point, the economy could grow at about eight per cent sustainably,” he said.
Dual relief and challenges
While banks face pressure as CBN tightens liquidity rules, the regulator also announced a slight easing for lenders.
The general CRR for commercial banks has been reduced from 50 per cent to 45 per cent.
This adjustment provides some relief, even as the new 75 per cent requirement on non-TSA deposits bites into balance sheets.
Market watchers note that the double-edged policy reflects the MPC’s balancing act.
CardinalStone, a Lagos-based investment advisory firm, said the CBN’s strategy was “hawkish in tone” despite a modest 50-basis-point cut in the Monetary Policy Rate (MPR) to 27 per cent.
“The MPC has demonstrated confidence in the disinflation trend, while tightening liquidity channels vulnerable to fiscal flows,” the firm observed.
The bigger picture: inflation, FX, and growth
The broader implication is that the apex bank is trying to strike equilibrium between stimulating economic growth and preserving macroeconomic stability.
Analysts agree that FAAC-related liquidity injections often create distortions in Nigeria’s currency market.
By sterilising such funds, the CBN hopes to prevent undue demand pressures in the parallel FX market.
At the same time, banks will be nudged to deepen financial intermediation in the private sector.
This could spur innovation in savings and lending products, as lenders compete to attract more retail deposits.
However, the transition may temporarily slow credit availability, especially for small and medium-sized enterprises already grappling with high interest rates.
Policy as a signal of discipline
For policymakers, the decision sends a strong signal to investors that Nigeria is committed to fiscal and monetary coordination.
With the Finance Minister now overseeing government spending approvals, the clampdown on excess liquidity reflects an intent to consolidate macroeconomic gains.
“This policy should reassure both domestic and foreign investors that Nigeria is serious about bringing stability to its markets,” Adebajo added.
As banks face pressure as CBN tightens liquidity rules, the immediate effect will be reduced reliance on government deposits and greater focus on mobilising private funds.
While this may strain margins in the short term, experts believe it will promote financial discipline, reduce inflationary risks, and strengthen Nigeria’s foreign exchange position over time.
The coming months will reveal whether commercial lenders can successfully adapt to the new environment by innovating and diversifying their funding sources.
But one thing is clear: the CBN’s latest move underscores its determination to address inflation and stabilise the economy, even if it means forcing banks out of their comfort zones.
