There is no single African economy, Central Banks are moving in opposite directions

Angola and the Democratic Republic of Congo cut interest rates in July, Ethiopia raised them, while the continent’s largest economies chose to hold steady. The divergence exposes deep differences in inflation, currency risk and the room central banks have to manoeuvre.

LAGOS — Africa’s largest economies are no longer marching to the same monetary beat. In July, Angola and the Democratic Republic of Congo lowered interest rates, Ethiopia tightened policy, while South Africa, Egypt, Nigeria, Kenya and Ghana left their benchmark rates unchanged.

At first glance, the split might appear to reflect little more than the continent’s vast inflation range, from barely above 1% in parts of North Africa to almost 16% in Nigeria. The explanation is more complicated. The decisions reveal differences in exposure to currency shocks, the composition of economic growth and, above all, the degree of confidence each central bank has in the future path of prices.

The result is a continent divided not merely by different rates of growth, but by sharply different degrees of monetary freedom. Some economies can already afford to support activity; others are still paying the price of currency depreciation and food shocks; a third group prefers to wait, wary that external risks could reignite inflation.

Ten economies, different cycles

Note: The indicators do not all refer to the same period. The growth column combines observed data and forecasts, as indicated, and therefore does not constitute a perfectly like-for-like comparison.

Cutting rates does not mean inflation has been defeated

Angola illustrates the distinction between prices moving in the right direction and a full return to stability. The National Bank of Angola cut its benchmark rate by 125 basis points to 15.75% after inflation eased to 9.33% in July, its first reading below 10% since 2015. It was the second rate cut of the year.

The move signals greater confidence in disinflation, but nominal interest rates remain high. A gap of more than six percentage points between the benchmark rate and current inflation suggests monetary conditions remain restrictive in real terms, although such a simplified comparison is no substitute for an estimate of the expected real interest rate. The central bank is therefore removing some of the restraint rather than declaring victory over inflation.

The Democratic Republic of Congo is in a more comfortable position. With inflation estimated at about 3%, the central bank lowered its policy rate by 100 basis points to 12.5%, its third cut of 2026. The apparent room for further easing is greater, but it remains dependent on the stability of the Congolese franc and foreign-exchange earnings generated by copper and cobalt.

That dependence matters. An economy powered by mineral exports can combine low inflation with robust growth and still remain vulnerable to falling commodity prices, production disruptions or capital outflows. Congolese monetary policy appears to have room to manoeuvre; that room is not unconditional.

Ethiopia’s rate rise shows the limits of rapid growth

At the opposite end of the spectrum, the National Bank of Ethiopia raised its benchmark rate from 15% to 16%, its first increase in two years. Inflation had accelerated to 13.4% in May, driven by food and transport costs.

The decision exposes a familiar tension in fast-growing economies. Estimates put Ethiopian growth at between 7.1% and 9.2%, supported by mining, construction and agriculture. But rapid expansion does not guarantee macroeconomic stability. If domestic demand, logistics costs or currency depreciation feed into prices, the central bank may be forced to restrain the economy before inflation becomes entrenched.

The one-percentage-point increase should also be interpreted cautiously. Against inflation of 13.4%, a 16% policy rate represents only moderate nominal tightening and limited real headroom when measured against past inflation. The institutional signal, a willingness to raise rates, may therefore matter almost as much as the size of the move.

The pauses conceal different risks

The largest group consists of central banks that left rates unchanged. That does not mean they share the same diagnosis.

In Nigeria, the 26.5% policy rate remains the highest among the ten economies examined, against inflation of 15.91%. The decision to hold reflects a delicate balance between containing prices and the cost that high interest rates impose on credit and investment. The naira’s recent relative stability helps, but it will need to persist if imported inflation is to fall sustainably and expectations are to improve.

Egypt faces a similar dilemma. Urban inflation accelerated from 14.3% in June to 14.9% in July, while the central bank’s main rate remained at 19.5%. Rising food prices illustrate why premature easing would be risky, even with economic growth forecast at 4.6%-4.7% in 2026.

In South Africa, the 7% rate was maintained by a four-to-two vote. The minority favoured an increase, signalling that concerns over inflation remain alive. With growth of just 0.5% in the first quarter, the central bank faces a particularly uncomfortable combination: inflation calls for caution while weak activity would benefit from easier financial conditions.

Ghana and Kenya also chose to wait. Ghana held its rate at 14% for a second consecutive meeting after five cuts, despite inflation falling to 4.6%. The pause can be read as an attempt to consolidate those gains and protect the currency rather than immediately exploit all the apparent room for further easing. In Kenya, July inflation of 6.5%, the highest in almost two years, justified keeping the rate at 8.75%, despite first-quarter growth of 5.3% year on year.

The Maghreb’s low inflation is an exception, with caveats

Morocco and Algeria sit at the bottom end of Africa’s inflation spectrum. In Morocco, prices are rising at an estimated 1.2%-1.5%, while Bank Al-Maghrib expects core inflation of just 0.2% in 2026. In Algeria, the latest figure cited in this comparison is from February, when annual inflation stood at roughly 1.2%, helped by falling agricultural prices.

Those numbers require caution. Low inflation may reflect improved agricultural supply and greater price stability, but also differences in subsidies, exchange-rate regimes and the construction of national price indices. Algeria’s figure is also less recent than those used for most of the other economies. The comparison points to an important divergence, not perfect methodological equivalence.

Dollar GDP rankings say as much about currencies as output

Ranking economies by nominal GDP adds another layer to the analysis. South Africa emerges as the continent’s largest economy, followed by Egypt and Nigeria. But rankings based on current-dollar GDP are shaped by exchange rates as well as real economic growth.

The depreciation of the naira has reduced the dollar value of Nigeria’s economy and contributed to its slide down the rankings, even though output expanded 3.89% year on year in the first quarter. Losing places in a dollar-denominated league table does not, therefore, imply a contraction of comparable magnitude in domestic production.

The reverse logic applies to the Democratic Republic of Congo. Forecast growth of 5.5%-5.9%, supported by demand for copper and cobalt, could increase the country’s economic weight. But any climb in the rankings will also depend on the exchange rate, mineral prices and the performance of competing economies.

For investors, that distinction is crucial. Real growth helps determine the expansion of profits and domestic demand; the exchange rate determines how much of that value survives when converted into dollars.

A common shock does not produce a common policy

Escalating conflict in the Middle East features in several central-bank statements as a source of uncertainty. The transmission channels are familiar: energy prices, shipping costs, imported inflation, exchange rates and international capital flows.

Yet the same external shock can demand very different responses. A net energy importer already struggling with high inflation has less room to absorb an oil-price increase than an exporter with stable domestic prices. A central bank with limited foreign-exchange reserves may be forced to defend its currency; another, enjoying falling inflation and stronger credibility, may be able to look through a temporary disruption.

That is why July’s divergence does not amount to a lack of co-ordination. It reflects different starting points. Angola and the Democratic Republic of Congo believe they can begin removing some monetary restraint; Ethiopia has concluded that risks have increased; Nigeria and Egypt cannot yet declare victory over inflation; and South Africa remains caught between weak growth and monetary caution.

The phrase “African markets” remains useful as a geographical convention, but it is becoming an increasingly blunt economic category. Countries differ not merely in the level of interest rates or inflation, but in institutional credibility, currency vulnerability, export structures and their capacity to absorb external shocks.

For investors, the conclusion is less convenient than a single continental narrative, but considerably more useful: Africa does not offer one macroeconomic bet. It offers many, and they are moving in opposite directions.
