Ghana has seen interest rates drop sharply since the beginning of this year, placing it first among 11 African countries.
However, the West African nation remains second with the highest interest rates on the continent, while Egypt is still ranked first with the highest yields.
Since the beginning of the year, the yield on the 91-day bill has gone down by 3.94 percentage points to 24.48%.
Similarly, that of the 182-day bill has also declined by 3.58 percentage points to 25.39%.
The declining interest rates will compel the Bank of Ghana to cut its monetary policy rate from the current 27%.
The country with the lowest interest rates in Africa is Rwanda, with the 91-day pegged at 7.05% and the 182-day at 7.39%.
This indicates that it has a low-interest rate environment.
