- Borrowing Costs Could Ease Further as Ghana Reference Rate Declines To 10.18%
Ghana’s benchmark lending rate declined to 10.18% in September 2026, from 10.61% in August, offering a modest signal that borrowing conditions in the banking sector could continue to improve as short-term market rates ease.
The Ghana Reference Rate, which provides a common base for the pricing of loans by commercial banks, fell by 0.43 percentage points, or 43 basis points, over the month. The latest rate was announced by the Ghana Association of Bankers using the industry-approved methodology and market indicators that feed into the benchmark.
The decline was driven mainly by lower Treasury bill and interbank market rates. The Treasury bill component dropped to 4.8856% from 5.7881%, while the interbank rate edged down to 10.20% from 10.23%.
The Bank of Ghana’s Monetary Policy Rate, another component of the reference-rate calculation, remained unchanged during the period. The combination of lower short-term government borrowing costs and slightly softer interbank conditions was therefore sufficient to pull the benchmark lower.
The movement could provide some relief to borrowers whose loan agreements are linked directly to the Ghana Reference Rate, particularly those on variable-rate facilities. But the size of any actual reduction in borrowing costs will depend on individual banks and the additional risk premiums they apply to customers.
Commercial lending rates are typically determined by adding a borrower-specific margin to the reference rate. Credit risk, collateral, loan duration, sector exposure, operating costs and the bank’s own funding position can therefore leave a significant gap between the GRR and the rate ultimately charged to a customer.
This means a lower reference rate does not automatically translate into an equivalent reduction in every lending rate. Borrowers with fixed-rate loans are also unlikely to experience an immediate change, while customers renegotiating facilities or taking new variable-rate loans may see a more direct benefit.
The September decline nevertheless adds to evidence that financing conditions have become less restrictive for parts of the economy. Average lending rates are reported to have fallen to around 15.00%, while some stronger borrowers are accessing credit at rates between 11.00% and 12.50%.
That dispersion is important. It suggests that improved conditions are not being experienced uniformly across the market, with borrowers considered less risky or able to provide stronger security benefiting more quickly than smaller businesses and households with weaker credit profiles.
The movement in the GRR also reflects a broader shift in domestic financial conditions during 2026. The benchmark stood at 11.71% in March, before dropping sharply to 10.06% in April and then easing to 10.03% in May and 10.02% in June.
It subsequently reversed direction, rising to 10.59% in July and 10.61% in August before declining again in September. That pattern shows that the cost environment remains fluid even as the broader direction of borrowing conditions appears more favourable than earlier in the year.
For businesses, the importance of sustained lower lending rates extends beyond the cost of servicing existing debt. Cheaper credit can improve the economics of working-capital facilities, inventory financing, equipment purchases and expansion projects that may previously have been difficult to justify under higher interest-rate conditions.
The effect can be particularly important for small and medium-sized enterprises, which tend to be more dependent on bank financing and more sensitive to interest costs than larger companies with access to alternative sources of capital. But for those businesses to benefit materially, reductions in market benchmarks will need to be reflected in the risk margins charged by lenders.
Banks, meanwhile, face a different calculation. Lower benchmark rates may reduce the yield available on some loans, but improved macroeconomic conditions can also reduce default risk, support credit demand and encourage competition for stronger borrowers.
That competition appears to be contributing to lower rates for selected customers. If the trend continues, banks may increasingly have to compete not only on deposit mobilisation and digital services but also on the pricing of credit.
The decline in Treasury bill rates is also significant because government securities compete with private-sector lending for bank funds. When short-term government instruments offer very attractive returns, banks may have less incentive to assume the additional risk associated with lending to businesses and households.
Lower Treasury yields can gradually change that trade-off. If the return on relatively low-risk government securities continues to fall, commercial lending may become comparatively more attractive, potentially encouraging banks to deploy more of their balance sheets towards private-sector credit.
That transmission, however, is not automatic. Banks will still require confidence in borrowers’ repayment capacity, while weaknesses in credit information, collateral enforcement or business cash flows can keep lending spreads elevated even when the reference rate falls.
The GRR was introduced in 2017 through collaboration between the Bank of Ghana and the banking industry to establish a more transparent and consistent basis for pricing loans. Its purpose is to provide a common reference point while allowing individual banks to price the specific risks associated with each borrower.
September’s decline to 10.18% is therefore best interpreted as an improvement in the underlying pricing environment rather than evidence that all borrowers will immediately receive cheaper credit.
For policymakers, the larger test is whether lower benchmark rates translate into meaningful credit growth to productive sectors of the economy. Falling interest rates provide limited economic benefit if lending remains concentrated among a narrow group of low-risk corporate borrowers.
If Treasury bill rates continue to soften and banking-sector competition intensifies, the September decline could become part of a broader easing cycle in commercial credit. That would strengthen the link between improving financial conditions and investment, employment and private-sector expansion.
For now, the 43-basis-point decline is modest but directionally important. The next question is whether banks pass enough of the improvement through to customers for lower benchmark rates to become genuinely lower borrowing costs.
