Africa Economic Outlook — September 2026

September exposed a widening divide in African monetary policy as renewed energy inflation collided with weak growth, uneven disinflation and limited fiscal space.

Executive Summary

Africa closed September with a common external shock but sharply different policy responses. Higher oil and freight costs raised inflation risks across the continent, yet domestic conditions produced a wide monetary-policy range: South Africa and Eswatini raised rates by 25 basis points, Ghana and Egypt held, and Nigeria cut its policy rate by 350 basis points.

The divergence is economically coherent. Southern Africa entered the shock with weak growth and rising fuel pressure. South Africa’s economy contracted by 0.2% in the second quarter, formal non-agricultural employment fell, and the South African Reserve Bank (SARB) lifted its 2026 inflation outlook. Eswatini’s inflation remained relatively low at 2.8% in August, but the Central Bank of Eswatini raised its bank rate to 7.0% to protect price stability and the Common Monetary Area transmission mechanism as regional energy risks intensified.

East Africa’s immediate challenge is supply-driven inflation. Kenya’s annual inflation rose to 6.8% in September, with transport prices up 15.6% and food prices up 9.5%. Zambia offered a more favourable counterpoint: annual inflation eased to 6.1%, returning close to the lower end of its 6%-8% target range.

West Africa ended the month with the strongest policy contrast. Nigeria reset its policy rate from 26.5% to 23.0% as disinflation created room to support activity, although high reserve requirements kept the overall stance restrictive. Ghana held at 14.0%, balancing inflation of 5.0% against oil, utility and exchange-rate risks. In North Africa, Egypt held its overnight deposit rate at 19.0%, despite moderating headline inflation, because geopolitical and energy risks remained elevated.

The outlook for October is therefore not a simple inflation story. It is a test of policy credibility under a negative supply shock. The key question is whether fuel-price increases remain a first-round adjustment or spread into transport fares, food distribution, wages and services inflation.

Africa Macro Overview

September’s central macroeconomic theme was the renewed oil-price shock. Supply disruption and geopolitical tension lifted crude and refined-product costs and increased shipping and insurance expenses. For oil importers, this worsens trade balances, fiscal subsidy costs and consumer inflation. Oil exporters gain revenue, but refining constraints and higher domestic fuel costs mean the benefit is not automatic.

The second theme was weaker policy synchronisation. During the previous global disinflation phase, many African central banks could move gradually toward easing. By September, country-specific conditions dominated. Economies with firmer external buffers or stronger disinflation retained room to hold or cut. Economies closely exposed to rand interest rates, fuel-price pass-through or unanchored expectations tightened.

The third theme was weak job-rich growth. South Africa’s second-quarter contraction and employment losses show that price stability is being defended against a soft real economy. Kenya and Ghana continued to show more resilient activity, but household welfare remained vulnerable to food and transport inflation. Across the continent, the quality of growth matters as much as the headline rate: high borrowing costs, weak formal employment and rising essentials can prevent aggregate growth from improving living standards.

Regional Developments

Southern Africa

Southern Africa ended September with the most difficult growth-inflation mix. South Africa’s real GDP contracted by 0.2% in the second quarter after six consecutive quarters of expansion. Mining led the weakness, while net exports deducted 1.1 percentage points from growth as import volumes rose faster than exports. Formal non-agricultural employment fell by 14,000 in the quarter and by 95,000 over the year to June.

Inflation was not exceptionally high in headline terms, rising to 4.4% in August from 4.3% in July, but its composition and trajectory concerned the SARB. Fuel inflation had reached 34.3% in June before moderating to 20.0% in August. The Bank raised the repo rate to 7.25% and projected headline inflation above 5% later in 2026 and early in 2027. It also reduced its 2026 growth forecast to 1.2% from 1.4%.

Eswatini followed with a 25-basis-point increase in its bank rate to 7.0%; the prime lending rate moved to 10.5%. The move came despite subdued headline inflation of 2.8% in August. The decision reflects the forward-looking risk from imported fuel, the lilangeni-rand link and the need to limit capital and inflation pressures within the Common Monetary Area.

The month ended with Eswatini announcing substantial fuel-price increases effective 2 October. Petrol and illuminating paraffin rise by E3.43 per litre, while the published diesel price points imply an E3.40 increase. The adjustment shifts September’s external energy shock directly into the October household and business cost base.

Zambia’s annual inflation eased to 6.1% in September from 6.2% in August, mainly reflecting food-price movements. This is a positive regional signal, but the country remains exposed to fuel costs, exchange-rate conditions and weather risks.

East Africa

Kenya’s inflation accelerated to 6.8% in September, still inside the official 2.5%-7.5% target band but moving closer to the upper limit. Food and non-alcoholic beverages rose 9.5% year on year, transport 15.6%, and housing, utilities and fuels 3.2%. The monthly CPI increase was 0.4%.

The composition matters for policy. Food and transport are highly visible household costs and can affect wage demands and expectations even when core inflation is better behaved. The Central Bank of Kenya had retained its policy rate at 8.75% in August. September’s data reduce the case for early easing unless energy or food pressures reverse.

For the broader region, the policy priority is supply resilience: food logistics, electricity reliability, strategic fuel management and exchange-rate stability. Higher interest rates cannot produce food or fuel, but they can prevent supply shocks from becoming persistent general inflation.

West Africa

Nigeria delivered the month’s largest rate move. The Central Bank of Nigeria reset the monetary policy rate to 23.0% from 26.5%, while retaining cash reserve requirements of 45% for deposit money banks, 16% for merchant banks and 75% for non-Treasury Single Account public-sector deposits. The combination signals selective easing rather than a broad liquidity expansion.

The rate reduction creates potential relief for credit pricing and investment, but the transmission will depend on banking liquidity, government borrowing, the naira and inflation expectations. With the CBN reporting inflation of 15.39%, Nigeria still has limited room for policy error.

Ghana held its policy rate at 14.0%. Inflation was 5.0% in August, below the lower bound of the medium-term target band, while core inflation measures and expectations were easing. However, higher oil prices, utility tariffs, transport fares and a potentially stronger US dollar argued for caution.

Ghana’s external sector remained a key buffer. Exports reached US$22.4 billion in the first eight months of 2026, compared with US$17.9 billion a year earlier, supported by gold, cocoa and crude oil. Imports increased to US$13.58 billion. Gross international reserves stood at US$12.0 billion, equivalent to 4.5 months of import cover, on 22 September.

North Africa

Egypt held its overnight deposit, lending and main-operation rates at 19.0%, 20.0% and 19.5%, respectively. Annual headline inflation eased to 14.5% in August, while core inflation was 14.9%. Monthly inflation had been near zero for three consecutive months, allowing the central bank to lower its inflation forecast.

The Central Bank of Egypt nevertheless retained a restrictive stance because energy, food and regional geopolitical risks remained tilted upward. Real GDP growth moderated to 4.7% in the second quarter from 5.0% in the first, while provisional net international reserves reached US$57.2 billion at the end of August.

Egypt’s position captures the broader North African dilemma: improving disinflation and reserve buffers coexist with unusually high exposure to regional conflict, shipping disruption, tourism sensitivity and imported commodity prices.

Country Focus

Eswatini: Low current inflation, high forward risk

Eswatini’s September rate increase should not be read as a reaction to current inflation alone. At 2.8% in August, inflation was contained. The more important issue was the prospective pass-through from oil prices and South African monetary conditions.

The fuel adjustment announced on 30 September confirms that forward risk. Petrol rises from E25.97 to E29.40 per litre and paraffin from E21.73 to E25.16. Diesel rises from E28.85 to a reported E32.25. These increases will affect freight, farming, public transport and lower-income households disproportionately.

The policy challenge is to cushion vulnerability without obscuring the fiscal cost. Any use of the Strategic Oil Reserve Fund should be reported transparently, including the amount absorbed, the remaining capacity and the conditions for withdrawal. Targeted support to public transport or vulnerable households is more sustainable than broad price suppression.

South Africa: Stagflation risk without a full stagflation outcome

South Africa is not in full stagflation: inflation remains moderate by historical standards and the SARB expects a second-half growth rebound. However, the combination of a quarterly contraction, employment losses, fuel inflation and higher interest rates resembles a stagflationary risk configuration.

The August merchandise trade surplus of R20.5 billion provides external support. Exports were R181.8 billion and imports R161.3 billion, including trade with Botswana, Eswatini, Lesotho and Namibia. Yet a sustained oil shock would weaken the terms of trade and raise the import bill. Structural reforms in electricity, rail, ports and municipal services remain the most credible route to better growth without reigniting inflation.

Public Finance and Debt Watch

Higher energy prices create a fiscal choice across Africa: pass the cost to consumers, reduce taxes, subsidise prices or allow arrears to accumulate in state energy entities. Each option carries a distributional or balance-sheet cost. Governments should publish these costs explicitly rather than treating price stabilisation as fiscally invisible.

South Africa’s national government gross loan debt stood at 78.2% of GDP at the end of June 2026, according to the SARB. Higher global and domestic yields increase the cost of refinancing and reduce room for countercyclical support. The August trade surplus is helpful, but it does not remove the need for expenditure discipline and growth-enhancing reform.

Ghana’s stronger export earnings and reserve buffer improve debt-service resilience, while Nigeria’s lower policy rate may reduce financing pressure at the margin. In both cases, fiscal dominance remains a risk if public borrowing prevents monetary easing from reaching productive private-sector credit.

For Eswatini, no new comprehensive September fiscal outturn or SACU-receipts update was available at the reporting cutoff. The immediate risk assessment therefore rests on fuel-price intervention, borrowing costs and the indirect effect of weak South African growth. This limits confidence in any precise month-end fiscal estimate.

Inflation and Monetary Policy Watch

September’s decisions divide into three groups:

• Tightening: South Africa and Eswatini raised rates by 25 basis points as fuel and expectations risks increased.
• Holding: Ghana and Egypt retained restrictive settings while assessing energy, currency and tariff pass-through.
• Easing: Nigeria cut by 350 basis points, but kept high reserve requirements, limiting the scale of liquidity expansion.

Kenya’s 6.8% inflation and Zambia’s 6.1% show why regional generalisation is dangerous. Both remain near or within target ranges, but Kenya’s inflation momentum and transport component are less benign. Policymakers should focus on breadth, persistence and expectations rather than headline inflation alone.

Trade, Commodities and External Sector

Oil remained the dominant risk to African external balances. Importing economies face higher fuel bills and freight costs, while exporters benefit through receipts but may still experience domestic inflation. Gold supported Ghana’s trade surplus and reserves, demonstrating the value of diversified commodity earnings during an oil shock.

South Africa’s R20.5 billion August trade surplus supported the rand and, indirectly, Common Monetary Area currencies. However, the SARB reported that South Africa’s terms of trade deteriorated in the second quarter because import prices, particularly for crude and refined petroleum, increased faster than export prices.

Regional integration institutions should treat logistics resilience as macroeconomic policy. Ports, border systems, rail corridors and fuel-storage infrastructure affect inflation, revenue collection and trade competitiveness simultaneously. AfCFTA implementation will deliver less near-term benefit if transport and energy costs continue to rise faster than tariff barriers fall.

Risk Outlook

The balance of risks for October is tilted to the downside for growth and upward for inflation.

1. Energy persistence: A prolonged oil and shipping shock would widen current-account deficits and raise fiscal intervention costs.
2. Second-round inflation: Transport fares, food distribution, wages and services could turn a temporary fuel shock into persistent inflation.
3. Tighter financing: Higher global yields may increase African sovereign refinancing costs and pressure currencies.
4. Weather: El Nino risks could weaken agricultural output and reverse recent food-price relief in Southern and East Africa.
5. Weak employment: South Africa’s job losses illustrate the social cost of low-growth adjustment.
6. Policy miscalibration: Premature easing could destabilise inflation and currencies, while excessive tightening could deepen already weak growth.

The principal upside risks are stronger commodity-export receipts, resilient currencies, improved harvests and faster progress on energy and logistics reform.
