10-year UST at ~5.11% with hawkish Fed: Long-dated African Eurobonds and FX face renewed duration and dollar pressure
Higher US yields and a hawkish Fed raise the global discount rate, pressuring long-dated African Eurobonds (notably Ghana and Zambia) and tightening dollar funding. Commodity exporters could offset some stress if China-driven demand holds; otherwise importers and FX-constrained sovereigns bear the brunt.

Desk brief
The US 10-year yield spiked to about 5. 11% on Sept. 24 alongside a still-hawkish Fed that raised the funds range to 3. 75–4. 00% earlier in September. That recomposes the global discount rate and lifts the opportunity cost of holding long-duration paper. Primary transmission is classic: higher US yields steepen the discount curve and apply mark-to-market losses to long-dated African hard-currency bonds, with outsized vulnerability concentrated in 10y+ maturities for higher-beta sovereigns such as Ghana and Zambia and quasi-sovereigns with long-dated external profiles.
Rising US real yields and a firmer dollar mechanically raise dollar funding costs and external debt-service burdens for dollar-exposed sovereigns and corporates. Countries with tight reserve buffers or large near-term amortisation — think Ghana’s long curve belly and Zambia’s long-dated Eurobonds — will see pressure on spread widening and rollover premia. Importers and those with large FX-denominated shortfalls (Kenya’s external curve and Egypt’s external financing needs) are exposed through reserve adequacy and weaker FX, which feeds domestic imported inflation and narrows policy room. China’s mixed activity thread complicates the commodity offset: stronger Chinese demand would support oil and metals, favouring exporters (Angola, Nigeria, Zambia, DRC, Ghana/Ivory Coast for cocoa/gold) and partially offsetting sovereign stress via fiscal receipts. But the signalling here is ambiguous; if China softens, exporters lose that buffer and will suffer the full impact of higher US yields and a stronger dollar. The desk will watch primary issuance windows and near-term amortisation schedules for Ghana, Zambia and Kenya as the conditional trigger for a material spread re-pricing.
