US 10yr at Multi‑Decade High: Higher Global Discount Rates Pressure Long‑Dated African Eurobonds and Dollar Funding

US 10‑year Treasury yields traded at their highest levels in roughly 24 years, reflecting a broad bond selloff and shifting Fed expectations. That rise in the global risk‑free rate increases the discount rate investors apply to risky assets and lifts dollar funding costs. Transmission to African credit occurs via elevated discount rates and a repricing of carry.

Long‑dated Eurobonds are most exposed: Ghana and Zambia maturities concentrated in the outer part of their curves will suffer more mark‑to‑market losses as duration multiplies the benchmark move. Higher US yields also widen the financing spread on dollar liabilities, raising rollover costs for sovereigns with upcoming external amortisations and for corporates dependent on cross‑border commercial paper or bank lines; Kenya’s external curve and dollar‑denominated corporate borrowers in Nigeria and Egypt face this channel.

A stronger dollar and higher risk‑free curve reduce the appeal of higher‑beta African paper, increasing sovereign and corporate spread premia until dollar funding costs normalise. Regional differentiation will matter: better‑funded North African sovereigns with shorter external maturity walls (Morocco, Egypt where applicable) should show more resilience than higher‑beta sub‑Saharan credits with concentrated long maturities (Ghana, Zambia).

The desk watches immediate movement in US long yields and US curve steepness; persistent elevation would force higher refinancing premia on African issuers with large external needs.
