Ghana Reference Rate dips to 10.03% in May, signalling possible loan rate cuts

Ghana’s Ghana Reference Rate (GRR) has recorded a slight decline for May 2026, dropping to 10.03% from 10.06% in April, signalling a possible easing of borrowing costs in the country’s banking sector.

The latest figure, calculated by JOYBUSINESS using the industry-approved formula, reflects marginal shifts in key financial indicators that influence lending rates. The GRR serves as the primary benchmark used by commercial banks in Ghana to determine interest rates on loans.

This modest drop is expected to translate into slight reductions in lending rates for loans negotiated between May 5 and June 1, 2026, particularly for customers on variable-rate facilities.

The decline in the GRR was mainly driven by a slight reduction in the interbank rate, which fell to 10.30% at the end of April 2026. This decrease helped offset a rise in Treasury bill rates, which increased from 4.81% to 4.92% during the same period.

JOYBUSINESS based its calculation on three key variables: Treasury bill rates, the interbank rate, and the monetary policy rate set by the Bank of Ghana. Despite the uptick in Treasury yields, the drop in interbank rates was sufficient to push the overall reference rate slightly downward.

The adjustment is likely to trigger a new round of marginal lending rate cuts by commercial banks. However, the benefits may not be immediate for all borrowers. Customers with fixed-rate loans are unlikely to see changes in their repayment terms, while those on variable-rate loans could experience a slight reduction in interest charges.

Additionally, borrowers with strong credit profiles may be in a better position to negotiate more favourable terms. Industry checks suggest that some banks are already offering loans at rates as low as the GRR minus five percentage points to highly creditworthy clients.

Chief Executive Officer of the Ghana Association of Banks, John Awuah, has also indicated that a number of banks have begun offering single-digit interest rates, reflecting improved conditions in the financial sector.

The latest decline comes at a time when businesses in Ghana continue to face tight credit conditions. These challenges are largely linked to ongoing liquidity management measures aimed at controlling inflation and stabilising the broader economy.

Recent trends show that the Ghana Reference Rate has been on a steady downward trajectory. It dropped significantly from 15.58% in January 2026 to 14.58% in February, then to 11.71% in March, before easing further to 10.06% in April and now 10.03% in May.

Looking further back, the GRR stood at 15.9% in December 2025 following a 350-basis-point cut in the policy rate to 18%, alongside a slight dip in Treasury bill rates. In contrast, November 2025 saw a marginal increase to 17.96%, driven by rising interbank and Treasury bill rates.

Overall, the rate has seen a sharp decline over the past year, falling from as high as 29.72% in January 2025 to 19.67% by August 2025, before continuing its downward trend into 2026.

The Ghana Reference Rate was introduced in 2017 by the Bank of Ghana in collaboration with the Ghana Association of Banks. It replaced the previous base-rate system to improve transparency, consistency, and fairness in loan pricing across the banking sector.
