Ghana’s latest monetary statistics, as revealed by the Bank of Ghana on September 24, are beginning to reveal a significant change in the pace, composition and transmission of liquidity through the economy, with reserve money expanding by a striking 29.7 percent year-on-year in August 2026, compared with just 4.5 percent a year earlier.

The acceleration is particularly noteworthy because it coincides with a substantial change in the Bank of Ghana’s cash-reserve framework for commercial banks.

At the same time, total liquidity, measured by broad money supply M2+, accelerated to 20.4% year-on-year from 16.6 percent over the comparable 12-month period, raising important questions about the eventual effects on inflation, the exchange rate and bank credit.

Ghana’s headline consumer inflation rose to 5.0 percent in August 2026 from 4.6 percent in July, according to the Ghana Statistical Service.

Economists are at pains to explain that the 20.4 percent expansion in M2+ is not, by itself, proof that monetary growth is causing the renewed inflation.

Prices are also affected by food supply, energy costs, exchange-rate movements, taxes and other supply-side factors.

Nevertheless, they warn that sustained money growth above the economy’s underlying real growth rate creates a potential medium-term inflationary channel.

The latest figures from the Bank of Ghana show reserve money rising from GH¢122.0 billion in August 2025 to GH¢158.2 billion in August 2026—an increase of GH¢36.2 billion, or 29.7 percent. By comparison, the year-on-year increase in August 2025 had been only 4.5 percent.

The most important change occurred after the BoG amended the previous dynamic Cash Reserve Ratio regime, replacing it with a uniform 20 percent requirement to be maintained in domestic currency.

The revised framework became effective in June/July 2026, with the BoG saying the objective was to improve liquidity management, strengthen monetary-policy transmission and support macroeconomic stability.

The change had a sizeable mechanical effect on banks’ reserve positions. The BoG estimated that about GH¢11.5 billion would be absorbed from the banking system through the new arrangement.

It subsequently reported that the decline in BoG securities of about GH¢10.6 billion, together with other liquidity withdrawals, suggested that the intended liquidity absorption had broadly been achieved.

That apparently contradictory combination—liquidity being absorbed while reserve money rises sharply—is explained by the composition of reserve money.

Commercial-bank reserves held at the central bank are themselves part of reserve money. Bank reserves rose from GH¢57.2 billion in August 2025 to GH¢77.7 billion in August 2026, while currency outside banks increased from GH¢56.8 billion to GH¢70.4 billion.

Thus, the surge in reserve money does not mean that an equivalent GH¢36 billion was released into the spending economy. A substantial portion represents banks’ balances held at the central bank as required liquidity.

The domestic component of monetary expansion nevertheless strengthened materially. Net domestic assets—the domestic counterpart of money creation—were growing at 17.2 percent year-on-year by August.

The increase reflects, among other things, stronger private-sector credit creation and changes in banks’ portfolios following the reserve-requirement reform.

Private-sector credit provides perhaps the clearest evidence that monetary expansion is beginning to transmit into the real economy. Nominal private-sector credit was growing by 35.5 percent year-on-year in August, while real credit growth was a substantial 29.0 percent. This is considerably faster than the 20.4 percent expansion in M2+.

For businesses, the implication is potentially greater availability of bank financing. The effect on the cost of credit, however, is more complicated. The BoG’s easing cycle had already brought the average lending rate down to 20.65 percent in June 2026 from 29.22 percent a year earlier, while the interbank rate had fallen from 29.00 percent to 9.81 percent.

The greater availability of liquidity therefore comes at a time when the cost of funds has been falling. If banks compete aggressively for good borrowers, stronger liquidity and declining funding costs could encourage further reductions in lending rates.

But if rapid credit growth begins to generate inflationary or foreign-exchange pressures, monetary authorities could eventually have to resist further reductions.

The external side of the monetary equation provides an important counterweight. Net foreign assets (NFA) were GH¢104.3 billion in August, down from GH¢111.3 billion in July and considerably below the GH¢139.1 billion recorded in May.

However, analysts point out that the distinction between monthly and annual movements is important. Despite the recent decline, August 2026 NFA remained 30.9 percent above its August 2025 level. Consequently, NFA did not reduce year-on-year M2+ growth; rather, its fall from the May/July levels helped moderate the more recent expansion of overall liquidity.

This distinction matters for the cedi. Stronger domestic money and credit growth can increase demand for goods, services and foreign currency. If the expansion of domestic liquidity exceeds the economy’s capacity to supply goods and services, some of the excess demand can migrate into imports and foreign exchange, putting pressure on the cedi.

So far, the exchange-rate consequences have been contained by stronger external buffers and the BoG’s foreign-exchange operations. But the interaction between rapidly growing domestic credit and a declining NFA position will remain important because sustained foreign-exchange demand can eventually transmit into imported inflation.

Ghana currently has an unusual combination: rapidly growing bank reserves, accelerating private-sector credit, expanding broad money and comparatively low policy rates.

This combination can support economic activity and investment, but it also requires careful calibration.

The critical indicator over coming months will not simply be reserve-money growth.

It will be whether the acceleration in M2+ and credit translates into stronger productive output or increasingly into consumer-prices and foreign-exchange demand.

If the former dominates, the monetary expansion could support Ghana’s recovery.

If the latter gains momentum, the same liquidity that is currently helping banks finance the private sector could become a source of renewed inflation and exchange-rate pressure.

The central monetary-policy challenge therefore is to ensure that the reserve-money surge generated by the new banking reserve framework remains largely an operational and liquidity-management phenomenon rather than becoming uncontrolled monetary expansion.
