Africa Daily Economic Briefing — 30 September 2026

An oil-driven inflation shock is pushing African monetary policy in different directions as South Africa and Eswatini tighten, Nigeria eases, and Ghana holds.

Executive Summary

African monetary policy is becoming more divergent as economies absorb the same external energy shock from very different starting points. South Africa and Eswatini have raised interest rates in response to renewed inflation risks, even as South African output contracted in the second quarter. Nigeria, by contrast, has cut its policy rate sharply as inflation has moderated, while Ghana has kept its rate unchanged amid strong growth and still-contained price pressures.

The common risk is oil. Brent crude remained above US$100 a barrel on 29 September, despite retreating as Middle Eastern exports recovered. For African oil importers, expensive fuel is worsening inflation, external balances, transport costs and fiscal pressure. For exporters, higher prices can support revenue and foreign exchange, but only if production and export volumes remain resilient.

South Africa’s latest Quarterly Bulletin underlines the difficult policy mix. Real GDP fell by 0.2% quarter on quarter in the second quarter, the current account moved from a surplus of 2.3% of GDP to a deficit of 2.6%, and fixed investment declined slightly. Yet fuel and services inflation remain sufficiently persistent for the South African Reserve Bank to have raised the policy rate to 7.25%. This combination of weak activity and renewed price pressure is also important for Eswatini through the currency peg, trade linkages and shared regional financial conditions.

Key Developments

1. South Africa’s weak growth collides with a renewed inflation shock

The South African Reserve Bank’s September Quarterly Bulletin shows that real GDP contracted by 0.2% quarter on quarter in the second quarter of 2026 after six consecutive quarters of expansion. Mining weakened, manufacturing contracted for a fourth consecutive quarter, and gross fixed capital formation edged lower. Household consumption rose by 0.4%, but inventory accumulation rather than final demand made the largest positive contribution to growth. Net exports subtracted 1.1 percentage points as import volumes rose faster than exports.

The external account also deteriorated. A smaller trade surplus and a wider services, income and transfer deficit shifted the current account from a surplus of 2.3% of GDP in the first quarter to a deficit of 2.6% in the second. Higher oil and refined-fuel import costs worsened the terms of trade, exposing the economy’s sensitivity to sustained energy-price pressure.

Despite soft growth, the Reserve Bank raised the policy rate by 25 basis points to 7.25%, effective 25 September. Headline inflation was 4.4% in August, and the Bank expects inflation to return to its 3% target only toward the end of 2027. It now projects annual growth of 1.2% in 2026, down from 1.4%.

Why it matters: South Africa faces a policy squeeze: tighter monetary conditions are needed to prevent the fuel shock from becoming embedded in inflation expectations, but higher borrowing costs will weigh on investment, household demand and fiscal financing. The growth outlook therefore depends increasingly on supply-side reforms, export performance and investment execution rather than interest-rate relief.

2. Nigeria delivers a large rate cut but keeps liquidity controls tight

The Central Bank of Nigeria reset its Monetary Policy Rate to 23% at its 21–22 September meeting, down from 26.5% in July. It also narrowed the standing facilities corridor to +50/-300 basis points around the policy rate. However, it retained the cash reserve requirement at 45% for deposit money banks, 16% for merchant banks and 75% for non-Treasury Single Account public-sector deposits.

The 350-basis-point move is a strong easing signal, supported by headline inflation of 15.39% shown in the central bank’s latest dashboard. Yet the unchanged reserve requirements show that the CBN is not moving to broad-based monetary accommodation. The policy mix aims to lower the benchmark cost of money while maintaining firm control over banking-system liquidity and foreign-exchange stability.

Why it matters: Lower rates could gradually reduce financing costs for government and the private sector, but transmission may remain uneven while reserve requirements are high. The durability of the easing cycle will depend on food prices, fiscal discipline, naira stability and whether renewed oil-price volatility improves export receipts more than it raises domestic energy costs.

3. Oil above US$100 intensifies the divide between importers and exporters

Brent crude traded at US$103.32 a barrel at 13:06 GMT on 29 September, after earlier gains gave way to evidence of recovering Middle Eastern exports. Brent was still heading for a monthly gain of about 14%. Exports from major Middle Eastern producers reportedly reached 12.8 million barrels a day in September, the highest since February, but regional supply risks remain elevated.

The shock is already visible in African data. South African consumer fuel inflation reached 34.3% in June before moderating to 20.0% in August. Kenya’s transport prices were 15.7% higher year on year in August. Eswatini has also cited energy costs as an important inflation risk.

Why it matters: Oil-importing governments face a difficult choice between passing higher costs to consumers, absorbing them through tax or subsidy adjustments, or allowing pressure to build in fuel-pricing systems. Revenue authorities should closely monitor fuel-tax collections, import VAT and the effect of higher transport costs on other tax bases. Oil exporters may receive a near-term fiscal windfall, but production capacity, subsidy costs and exchange-rate management will determine the net benefit.

Country Watch

South Africa

The latest data reinforce a low-growth, higher-inflation picture. Unemployment rose to 33.6% in the second quarter, while surveyed employment fell by 16,000. The household debt-to-disposable-income ratio eased to 61.3%, but weak labour absorption and higher interest rates will constrain consumption. Today’s scheduled producer-price and capital-expenditure releases will provide fresh evidence on pipeline inflation and investment.

Nigeria

Nigeria’s rate cut places greater weight on policy credibility outside the headline rate. With the policy rate at 23% and inflation at 15.39%, the real policy rate remains positive on a simple ex-post basis. The next test is whether easing supports credit without destabilising the naira or reigniting inflation. High reserve requirements suggest the central bank intends to manage that transition cautiously.

Kenya

Kenya’s annual inflation rate rose to 6.6% in August from 6.5% in July, driven particularly by food and non-alcoholic beverages at 9.0% and transport at 15.7%. The Central Bank of Kenya had held its policy rate at 8.75% in August and projected growth of 4.9% for 2026.

Kenya is due to publish September inflation, second-quarter GDP, second-quarter balance-of-payments data and several producer and construction price indicators later today. These releases will be important for assessing whether growth is holding up as the fuel shock intensifies and whether the external balance is absorbing the higher import bill.

Other Notable Developments

Eswatini: The Central Bank of Eswatini raised its discount rate by 25 basis points to 7.0%, effective 26 September, following South Africa’s rate increase. Annual inflation rose to 2.8% in August, while the Bank lowered its 2026 inflation forecast to 2.52%. It reported foreign reserves of E11.4 billion, equivalent to 2.6 months of import cover, on 18 September and preliminary public debt of E43.1 billion, or 41.4% of GDP, at end-August.

Ghana: The Bank of Ghana kept its policy rate at 14% for a third consecutive meeting. Official data show annual inflation at 5.0% in August and real GDP growth of 6.0% in the second quarter. This gives the central bank room to hold rates steady, but rapid private-sector credit growth and the renewed global oil shock argue for caution.

Liberia: The IMF completed reviews under Liberia’s Extended Credit Facility and Resilience and Sustainability Facility, enabling immediate disbursements of about US$26.2 million and US$24.0 million respectively. The IMF projects growth of 5.5% in 2026, supported by mining, construction and manufacturing, while highlighting risks from fuel prices, donor support and commodity volatility.

Markets and Commodities

  • Oil: Brent remained above US$100 a barrel on 29 September and was on course for a substantial monthly gain. This is the day’s most consequential market variable for inflation and external balances across Africa.
  • Gold: Spot gold recovered to around US$4,144 an ounce early on 29 September after touching a seven-week low, supported by geopolitical uncertainty. Higher gold prices benefit major African producers, but gains may be offset where fuel and capital-import costs rise simultaneously.
  • South African rates: The 10-year government bond yield reached 8.91% on 11 September amid higher oil prices and expectations of tighter-for-longer policy. Elevated yields increase the cost of fiscal financing and can spill over into regional markets.
  • Currencies: The rand’s resilience has partly limited imported inflation in South Africa and, through the one-to-one lilangeni peg, in Eswatini. Continued support depends on global risk appetite, commodity prices and domestic fiscal credibility.

Policy Implications

  1. Monetary policy must distinguish first-round from persistent effects. Central banks cannot produce oil, but they can limit second-round effects on wages, services prices and expectations. The appropriate response will differ according to the inflation starting point and currency vulnerability.

  2. Fiscal authorities should avoid broad, open-ended fuel subsidies. Where relief is necessary, temporary and targeted support is less damaging to budgets and price signals. Transparent fuel-pricing mechanisms are especially important when oil prices are volatile.

  3. Revenue agencies need scenario-based cash-flow planning. High oil prices may raise import VAT and excise receipts in nominal terms while weakening demand, increasing refund pressures and compressing other tax bases. Net revenue effects should not be assumed to be positive.

  4. South Africa and Eswatini need stronger buffers. South Africa’s swing into a current-account deficit and Eswatini’s 2.6 months of import cover increase the value of export diversification, disciplined public borrowing and reliable regional trade logistics.

  5. Rate cuts require supporting credibility. Nigeria’s large cut can support activity, but only if fiscal, liquidity and exchange-rate policies continue to anchor expectations. Ghana’s hold reflects a different balance: strong growth permits patience while external risks are reassessed.

What to Watch Next

  • Kenya’s September inflation, second-quarter GDP and balance-of-payments releases later today.
  • South Africa’s August producer-price inflation and second-quarter capital-expenditure data later today.
  • Whether Brent crude remains above US$100 and how quickly higher prices feed into October fuel adjustments.
  • Currency and bond-market responses to the contrasting policy moves in South Africa, Eswatini, Nigeria and Ghana.
  • Evidence that the oil shock is broadening from transport costs into services inflation, wages and inflation expectations.
