On 28 September 2026 the US 10-year Treasury yield rose above 5.2% (closing 5.241%), a global repricing that raises the benchmark discount rate and increases mark-to-market losses on long-dated African dollar bonds, while adding FX and rollover pressure for dollar-importing African economies.
The desk brief
On 28 September 2026 the US 10-year Treasury yield rose above 5.2% (closing 5.241%), a global repricing that raises the benchmark discount rate and increases mark-to-market losses on long-dated African dollar bonds, while adding FX and rollover pressure for dollar-importing African economies.
Higher US Treasury yields lift the global dollar discount rate, which mechanically increases duration-driven mark-to-market losses on long-dated dollar sovereign and corporate bonds. For African importers reliant on rolling or new dollar funding, higher benchmark rates raise rollover costs and FX pressure through tighter external financing conditions. Commodity-exporting countries may see partial offset if export receipts rise, but their dollar funding costs still increase.
US PCE inflation release and the monthly US jobs report this week, which could reinforce or reverse the Treasury repricing.
