Accra: The Bank of Ghana's recent withdrawal of GHS8.48 billion from the financial system through its 14-day bill auction on August 5 marks a significant reduction in liquidity management operations. This amount, representing a 48.83% decrease from the GHS16.57 billion withdrawn on July 27, is viewed by bank treasurers and monetary economists as evidence of the central bank's effective new liquidity management strategy.
According to Ghana Web, the August 5 amount was also 8.37% below the GHS9.25 billion absorbed on July 22 and 27.41% below the GHS11.68 billion sold on July 15. These figures are notably lower than the GHS14.42 billion withdrawn through 14-day bills on July 6, signaling a marked moderation in the scale of the Bank of Ghana's liquidity sterilization efforts. The central bank attributes this success to the recently implemented uniform 20% Cash Reserve Ratio (CRR), which replaced the previous dynamic CRR for commercial banks.
The Bank of Ghana has observed a significant reduction in the stock of Open Market Operations (OMO) since the transition to the uniform CRR on June 4, 2026. The central bank's official statement highlights that the new CRR framework has simplified regulations, enabling banks to better plan and provision for the CRR. The BoG notes that the transition has been orderly, with banks generally complying with the revised requirement, ensuring that liquidity conditions align with the Bank's inflation expectations and foreign exchange operation goals.
At the time of transitioning, 17 of the 23 banks were already provisioning at an effective CRR of 25% under the previous dynamic framework. Only six banks operated below that level, with three at 20% and the other three at 15%. The BoG projected the absorption of about GHS11.5 billion from the market through the new uniform 20% CRR, maintained in domestic currency, at no cost to the central bank.
The shift to a uniform CRR represents a fundamental change in the central bank's approach to managing excess liquidity in the banking system. By emphasizing non-interest paying reserve requirements over interest-bearing BoG bills, the BoG is reducing operating costs while maintaining its ability to influence monetary conditions. The simpler CRR arrangement now requires every bank to maintain a 20% CRR in domestic currency, a move projected to decrease the issuance of BoG bills to commercial banks.
This strategic shift comes as liquidity expanded through stronger deposit growth, foreign exchange accumulation, gold purchases, and improved fiscal conditions. The BoG had to increasingly mop up surplus liquidity through BoG securities, which incurred significant quasi-fiscal costs on its balance sheet, contributing to a negative equity position of GHS96.28 billion by the end of 2025.
The central bank's reduction in the effective tenor of BoG bills from 56-day to 14-day maturities further supports this transition, offering greater flexibility in managing liquidity conditions. This approach allows the BoG to recalibrate liquidity more frequently, reducing the risk of over- or under-sterilizing the financial system and limiting the accumulation of interest obligations.
By immobilizing 20% of banks' deposits, the CRR automatically dampens inflationary pressures without requiring continuous interest payments from the central bank. The continued availability of 14-day BoG bills provides the flexibility needed to fine-tune liquidity as market conditions change.
