The week’s biggest market story did not come from an index level but from the commodity tape: Brent crude fell 8.6% over the week to $91.02 a barrel, a sharp enough move to reshuffle sector leadership from Lagos to Johannesburg. At the same time, gold rose 2.0% to $4,587.8 an ounce, giving South African miners a clear offset just as oil-linked names lost momentum.
Key figures
- Brent: $91.02/bbl, down 8.6% on the week

- Cocoa: $3,901, down 4.8%
- USD/ZAR: 16.2329, with the dollar down 0.83%
- USD/NGN: 1,369.9, with the dollar down 0.26%
Market context: commodities set the tone for African stock markets today
Across African stock markets today, the week of May 25-29, 2026 showed again that when commodities move by 3% to 9% in a few sessions, African equities first react through sector channels and only then through broader index performance. According to the global headlines in the macro backdrop, oil weakened as U.S.-Iran talks continued and as the 2026 Brent outlook turned more bearish. That matters directly for Africa: lower crude prices improve the import bill for markets such as Morocco, Tunisia and Kenya, but they also reduce the relative earnings appeal of listed producers in Nigeria and South Africa.
