Over the past five weeks, observers of the Treasury Bill market have witnessed something very quiet but highly impactful. Ghana’s 91-day treasury bill rate has ticked up steadily: from 11.08 percent on December 22 to 11.19 percent by January 17, rising marginally but consistently.
On the face value, the changes may seem tiny. But in the world of economics, these small shifts can send ripples through the credit market and can end in the pockets of households and businesses waiting for cheaper loans.
So why are people anticipating cheaper loans watch the short-term government bill so closely? Simply, the answer lies in how interest rates or lending rates are determined in Ghana’s economy.
A Chain Reaction in Rates
The 91-day treasury bill rate is one of the most important benchmarks in Ghana. Because it’s a short-term, virtually risk-free investment, it sets a baseline for how much return investors demand from money markets.
This baseline feeds directly into the Ghana Reference Rate (GRR), which is a measure that reflects the average cost of funds for banks. The GRR doesn’t automatically become lending rates, but it heavily influences how banks price loans.
In other words, the 91-Day T-Bill rate is an integral part of the ingredients that determine the GRR before banks add their margins to arrive at the interest rate households and businesses pay on loans.
Here’s the practical chain:
If all other things remain the same, when the 91-Day Treasury Bill Rate rises ➝ GRR nudges higher ➝Banks’ cost of funds stays elevated ➝Lending rates may not fall, and could even rise.
Moreover, if banks can get slightly better returns on safe government bills, they become less eager to cut interest on loans. And because banks build their lending rates off the GRR, the anticipated fall in lending rates could be pushed further out.
Why This Matters for Households and Businesses
Many Ghanaians, from entrepreneurs planning new ventures to households looking to refinance older debts, have been hoping for relief in the form of lower borrowing costs. That hope has been anchored in expectations that declining inflation and a stable policy rate would lead to cheaper credit.
But now with the steady rise in the 91-day T-bill rate, is it a sign that money markets are tightening, not loosening?
Could this upward trend keep the GRR from falling as fast as expected, or at all? If the GRR stays elevated, will banks really lower lending rates for customers?
Not a Definitive Forecast — But a Growing Concern
It’s important to stress that the recent increases in the T-bill rate are modest. They don’t guarantee that lending rates will rise, or even stay high. Bank lending decisions also depend on loan demand, credit risk, and internal cost structures.
However, the relationship between short-term treasury rates and lending costs is real. And as the 91-day rate inches up, it raises a practical question for policymakers and borrowers alike:
Can expectations of lower credit costs survive when the benchmark that feeds into the system is rising? Only time and developments in the economy can tell.
