Africa Daily Economic Briefing — 28 September 2026

African central banks are splitting between renewed inflation defence and cautious easing as oil exceeds $100 a barrel and global financing conditions tighten.

Executive Summary

African economies begin the week facing a sharper trade-off between inflation control and growth support. Brent crude rose as much as 3% to $107.16 a barrel on Monday as stalled US-Iran talks sustained concern over the Strait of Hormuz. Higher fuel and freight costs are feeding into inflation expectations just as global bond yields rise and the US dollar strengthens.

That external shock is producing different policy responses. The South African Reserve Bank (SARB) raised its repo rate by 25 basis points to 7.25%, citing higher fuel costs and upside inflation risks even after the economy contracted in the second quarter. The Central Bank of Eswatini followed with a 25-basis-point increase in its discount rate to 7.00%, supporting the exchange-rate peg and guarding against imported inflation. Nigeria moved in the opposite direction, cutting its monetary policy rate from 26.5% to 23%, while Ghana held its rate at 14%.

The divergence reflects different starting points rather than a common continental cycle. Policymakers must weigh domestic inflation and currency conditions against weak investment, expensive credit and a less supportive global financing environment. For businesses and households, energy costs and borrowing conditions are again becoming the most immediate transmission channels.

Key Developments

1. Oil above $100 raises inflation and fiscal risks

Brent crude jumped as much as 3% to $107.16 a barrel in Monday trading, bringing its September gain to nearly 20%, according to Reuters market reporting. The rise followed limited progress in US-Iran talks over reopening the Strait of Hormuz. Global equities weakened, while longer-dated US Treasury yields remained close to multi-decade highs.

The African impact will be uneven. Oil exporters such as Angola and Nigeria may gain export and fiscal revenue if production volumes and collection systems hold up. For net importers, however, expensive crude increases fuel-import bills, transport costs and pressure on foreign-exchange reserves. Regulated or subsidised fuel-price systems may delay the household impact, but they can shift the burden onto public finances or create payment arrears.

2. Southern Africa tightens despite weak growth

The SARB unanimously raised the repo rate by 25 basis points to 7.25%, effective 25 September. Headline inflation was 4.4% in August, but the Bank expects it to move above 5% later in 2026 and early in 2027, mainly because of higher fuel prices and persistent services inflation. It now projects inflation returning to the 3% target only towards the end of 2027.

The decision comes against a soft growth backdrop. South Africa’s real GDP contracted by 0.2% quarter on quarter in the second quarter after expanding by 0.4% in the first. Mining fell by 3.0%, trade by 1.9% and manufacturing by 1.8%. The SARB reduced its 2026 growth forecast to 1.2% and judged risks to be tilted to the downside.

Eswatini raised its discount rate by 25 basis points to 7.00%, effective 26 September, while the prime lending rate increased to 10.50%. Domestic inflation was 2.8% in August, but the move narrows the policy-rate differential with South Africa and provides additional protection for the lilangeni-rand peg. The immediate cost is tighter financing for households and firms in an economy where credit conditions already matter heavily for private investment.

3. West Africa preserves more room for domestic differentiation

The Central Bank of Nigeria reset its policy rate to 23% from 26.5%, a 350-basis-point reduction, while keeping the cash reserve requirement for deposit money banks at 45%. Nigeria’s headline inflation eased marginally to 15.39% in August, with food inflation at 19.57% and core inflation at 13.29%.

The rate cut should reduce the policy constraint on lending at the margin, but a 23% benchmark and high reserve requirements still represent restrictive monetary conditions. We assess that the scale of the cut reflects confidence in recent disinflation, but its durability will depend on the naira, food supply, liquidity management and the pass-through from higher oil and refined-product prices.

Ghana held its policy rate at 14% on 24 September. The decision preserves a buffer against renewed external price pressure after rapid easing earlier in the cycle. With inflation back within the target band, the Bank of Ghana has more room than many peers to balance disinflation gains against growth and credit conditions, but rising oil prices argue for caution.

Country Watch

South Africa

The combination of a Q2 contraction and a rate increase intensifies the policy trade-off. Higher debt-service costs will weigh on rate-sensitive consumption and investment, while the fuel shock is likely to raise logistics and operating costs. The rand’s resilience has so far limited imported-price pressure, but higher global yields and a stronger dollar leave little room for complacency. Fiscal authorities also face a more expensive borrowing environment as global long-term yields rise.

Nigeria

The CBN’s rate cut is the day’s most significant African easing signal. It could improve sentiment among borrowers and investors if it is accompanied by stable foreign-exchange conditions and disciplined liquidity management. However, households still face food inflation close to 20%, and higher global oil prices do not automatically translate into consumer relief because refined-product costs, exchange-rate dynamics and domestic supply constraints remain important.

Kenya

Kenya’s August inflation rate was 6.6%, driven by food and non-alcoholic beverages at 9.0%, transport at 15.7%, and housing, water, electricity, gas and other fuels at 3.6%. The oil shock therefore lands on an already visible transport-price channel. This increases the importance of exchange-rate stability, fuel-pricing decisions and food-supply conditions for the next inflation release.

Other Notable Developments

The Bank of Ghana kept its policy rate at 14%, favouring consolidation of recent disinflation gains. In East Africa, finance and central-bank officials concluded meetings on 25 September aimed at improving budget credibility, aligning tax policies and strengthening joint economic assessment as the region prepares for the East African Monetary Union. The EAC also reactivated work on regional capital-market integration, which could broaden financing options over time but will require stronger regulatory and macroeconomic convergence.

Markets and Commodities

  • Oil: Brent traded as high as $107.16 a barrel on 28 September, up nearly 20% for the month at that point. The balance of risk remains upward while Hormuz uncertainty persists.
  • Gold: Gold fell about 3% to $4,151 an ounce in Monday trading as global yields rose. Despite gold’s defensive role, higher real and nominal yields can pressure non-yielding assets.
  • Global rates: The US 30-year Treasury yield traded near 5.52%, close to its highest level since 2004. Higher benchmark yields raise the refinancing cost for African sovereigns and corporates seeking hard-currency funding.
  • Currencies: A stronger dollar and elevated oil prices create a difficult combination for fuel-importing African economies: imported energy costs rise while local currencies face pressure. Countries with credible policy frameworks and stronger reserve buffers will be better placed to absorb the shock.

Market figures are intraday observations reported on 28 September 2026 and may differ from closing levels.

Policy Implications

  1. Fuel-price transmission requires active management. Governments should publish transparent pricing calculations and quantify any subsidy or stabilisation cost. Delaying adjustments without a funded mechanism can convert an inflation problem into a fiscal and arrears problem.

  2. Central-bank divergence is rational, but communication is crucial. Nigeria’s easing and Southern Africa’s tightening reflect different inflation paths and exchange-rate constraints. Clear explanations of reaction functions will be essential to preserve credibility.

  3. Revenue gains for oil exporters should not be treated as permanent. Windfall receipts are best directed toward buffers, debt reduction and priority capital spending rather than recurrent commitments.

  4. Revenue authorities should monitor valuation and compliance effects. Higher import prices may raise nominal customs and VAT collections, but weaker volumes and household demand can offset the gain. Collection agencies should separate price effects from real tax-base growth.

  5. Regional coordination is becoming more valuable. The EAC’s work on budget credibility and monetary coordination is timely. Similar attention across African regional blocs should focus on payment systems, customs efficiency, fiscal transparency and mechanisms for managing external shocks.
