The Ghana Reference Rate (GRR), a key benchmark used by commercial banks to set loan interest rates, increased to 10.59% in July 2026. This is up from 10.02% in June.
This marginal rise, announced by the Ghana Association of Banks on July 1, 2026, will likely cause a slight increase in commercial bank lending rates next month. The GRR is calculated using three main factors: Treasury bill rates, the interbank rate, and the Bank of Ghana’s Monetary Policy Rate. The current increase will impact new loans and variable-rate existing loans for businesses and individuals.
This upward movement in the GRR follows a period of decline and reflects broader efforts to manage Ghana's financial stability. The cost of borrowing for businesses has been tight due to measures aimed at controlling inflation and ensuring macroeconomic balance. Ghana's central bank has been actively involved in adjusting financial tools to stabilize the cedi, Ghana's currency.
Industry data indicates the July GRR increase stemmed mainly from two factors. First, the 91-day Treasury bill rate saw an upward adjustment. Second, the Bank of Ghana (BoG) raised the Cash Reserve Ratio (CRR) to 20% from 15%. The CRR is the amount of money banks must hold as reserves, restricting the funds available for lending.
Previously, banks operated under a tiered CRR system. The BoG replaced this with a uniform 20% CRR for all banks, regardless of their loan-to-deposit ratio. Dr. Johnson Asiama, Governor of the Bank of Ghana, explained to commercial bank chief executives that this higher reserve requirement aims to boost liquidity management. It also supports efforts to stabilize the cedi.
The increase in the Ghana Reference Rate could trigger another round of loan rate adjustments by commercial banks. Borrowers with fixed-rate loan facilities will not see immediate changes. Businesses with strong credit histories may also experience minimal changes in their borrowing costs. Any future increase in the Monetary Policy Rate, driven by global events, could push borrowing costs even higher, say analysts.
The GRR serves as the primary benchmark for loan pricing across Ghana's banking sector. The latest increase comes after the rate saw a decline in recent months. The GRR dropped from 15.58% in January 2026 to 10.02% in June before rising to 10.59% in July. The Bank of Ghana introduced the GRR in 2017, working with the Ghana Association of Banks. Its purpose was to provide a clear and consistent benchmark for determining lending rates.
