BoG says GH¢11.5bn liquidity withdrawal under new reserve rule progressing smoothly

The Bank of Ghana (BoG) has said the initial implementation of its new uniform 20% Cash Reserve Ratio (CRR) has proceeded smoothly, with early evidence indicating that the policy has withdrawn approximately GH¢11.5 billion from the banking system while preserving adequate liquidity across the financial sector.

The assessment offers the first official indication that one of the central bank’s most significant monetary policy adjustments in recent years is achieving its intended objective of tightening liquidity conditions without creating instability in the banking system.

In its latest bi-monthly responses to questions from the media, the central bank said commercial banks have generally complied with the revised reserve requirement and that financial markets have continued to function in an orderly manner since the policy took effect.

The uniform CRR forms part of the Bank of Ghana’s broader monetary tightening framework aimed at improving liquidity management, strengthening the transmission of monetary policy decisions and reinforcing macroeconomic stability as authorities continue efforts to consolidate gains in inflation and exchange rate management.

According to the central bank, it has been closely monitoring liquidity conditions, money market developments, credit growth and foreign exchange market activity since introducing the revised reserve requirement.

“The adoption of the new CRR policy was primarily aimed at strengthening liquidity management, improving monetary policy transmission, and supporting overall macroeconomic stability,” the Bank stated.

It added that the revised framework is designed to ensure liquidity conditions remain consistent with the central bank’s inflation objectives while complementing its foreign exchange operations.

The BoG, however, cautioned that it remains too early to draw definitive conclusions regarding the policy’s full economic impact.

“Compared to the period when the previous CRR framework was in place, a one-month span may be too short to assess the overall impact of the new CRR policy. Nonetheless, the Bank will continue to review data and industry feedback. The Bank’s goal is to ensure that the policy promotes stability, resilience, and growth,” the central bank said.

Liquidity withdrawal largely achieved

Before introducing the uniform reserve requirement, the Bank had estimated that approximately GH¢11.5 billion would be withdrawn from the financial system as banks transferred additional funds into non-interest-bearing reserves held at the central bank.

According to the latest assessment, those projections have largely materialised.

The Bank said a decline of approximately GH¢10.6 billion in outstanding Bank of Ghana securities shortly after implementation—combined with other liquidity absorption measures—indicates that the intended withdrawal has been broadly achieved.

“The observed decline in the Bank of Ghana securities of about GH¢10.6 billion shortly after the implementation date, together with other liquidity withdrawals, suggests that the projected liquidity absorption target was largely achieved, in aggregate terms,” it noted.

The policy requires banks to maintain reserves equivalent to 20% of eligible deposits in domestic currency with the central bank, replacing the previous dynamic reserve framework that imposed varying effective reserve requirements across institutions.

Limited disruption for most banks

The BoG also disclosed that the adjustment was less disruptive than initially anticipated because the majority of banks were already maintaining relatively high reserve balances under the previous system.

According to the central bank, 17 of Ghana’s 23 banks were already operating at an effective reserve ratio of approximately 25% under the former dynamic CRR framework before the reform took effect.

Only six institutions required significant adjustment, with three previously operating at an effective CRR of 20% and another three at 15%.

That distribution helped reduce transition risks and explains why implementation has so far been relatively orderly despite the sizeable liquidity withdrawal.

Why the policy matters

For investors and financial markets, the new reserve requirement represents more than a technical banking regulation. Cash Reserve Ratios are among the most powerful liquidity management tools available to central banks because they directly influence how much money commercial banks can deploy for lending and investment.

By immobilising a larger share of bank deposits at the central bank without paying interest, the policy reduces excess liquidity in the financial system, helping the BoG reinforce its tight monetary policy stance beyond changes in the policy rate alone.

The approach also reduces the need for the central bank to rely heavily on short-term liquidity sterilisation instruments, potentially lowering its own interest costs while enhancing the effectiveness of monetary policy transmission.

The challenge, however, will be ensuring that tighter liquidity conditions do not significantly constrain private sector credit or increase funding costs for businesses if maintained over an extended period.

For now, the Bank of Ghana’s initial assessment suggests the banking sector has adjusted to the new framework without major disruptions, providing policymakers with confidence that the revised reserve regime can support inflation management while preserving financial system stability.

The coming months will determine whether the policy continues to balance those objectives as broader economic conditions evolve.
