Ghana’s 5% Inflation Reopens Debate Over BoG’s 14% Policy Rate

Ghana’s August inflation reading has created an unusual monetary-policy configuration.

Headline inflation is 5.0 percent, below the Bank of Ghana’s 6 to 10 percent medium-term target band, while the Monetary Policy Rate remains at 14 percent.

With the next Monetary Policy Committee meetings scheduled for September 22 to 24, the gap between those two numbers is bound to intensify the debate over whether the Bank should cut again or keep its remaining policy buffer intact.

The case is less straightforward than subtracting 5 from 14. The policy rate is set with future inflation in mind, and the rates actually faced by government, banks, firms and households have already fallen considerably.

The September decision is therefore a question of timing: has inflation fallen far enough, and are the risks contained enough, to justify further easing?

The Ghana Statistical Service reports that annual inflation rose to 5.0 percent in August from 4.6 percent in July.

That was a 0.4 percentage-point increase, but it did not extend an uninterrupted rise: inflation had been 5.3 percent in June before falling in July. August therefore points to renewed pressure after one month of easing, not yet to a sustained re-acceleration.

The simple contemporaneous spread between the 14 percent policy rate and 5 percent inflation is nine percentage points. That spread is useful as a first indication of how restrictive policy may look today, but it should not be treated as a definitive forward-looking real policy rate.

Expected inflation, banking-system liquidity, exchange-rate risk, borrower risk and government-security yields all affect the monetary conditions that eventually reach the economy.

The Bank has already delivered a large easing cycle. Its policy-rate history shows the MPR at 28 percent in May 2025, before cuts to 25 percent in July, 21.5 percent in September, 18 percent in November, 15.5 percent in January 2026 and 14 percent in March.

The issue facing the MPC is therefore not whether easing should begin. It is whether the next reduction should come now or after more evidence that the inflation outlook is secure.

The strongest reason to avoid reading monetary conditions from the policy rate alone is the behaviour of market interest rates.

Bank of Ghana data for June put the Ghana Reference Rate at 10.0 percent, down from 23.8 percent a year earlier, while average bank lending rates fell to 15.6 percent from 27.0 percent. The 91-day Treasury bill yield was 5.3 percent in June and has since fallen below 5 percent.

Short-term government borrowing costs have therefore fallen much faster than the MPR. Private-sector credit has also accelerated: the July MPC record reported year-on-year growth of 41.2 percent in June, or 34.1 percent after adjusting for inflation. Those figures do not mean credit is equally accessible to every firm or household, but they do show that financial conditions have already loosened materially.

For businesses, lower lending rates can reduce the cost of working capital and make investment projects easier to finance. For households, they can improve the affordability of mortgages and other loans.

The other side of the transmission is that very rapid credit growth can add to demand, especially if production does not expand at a similar pace. That is one reason the MPC must consider the whole financial system rather than the headline inflation number in isolation.
