US 10‑Year Near 4.80%: Higher US Rates Reprice Duration in Long‑Dated African Eurobonds
Higher US 10‑year yields and increased Fed hike odds lift global discount rates, pressuring long‑dated African Eurobonds (notably Ghana and Zambia) via duration and funding channels and tightening dollar liquidity for FX‑vulnerable sovereigns and corporates.

Desk brief
The US 10‑year trading around 4. 79–4. 80% and a materially higher market-implied probability of a September Fed hike (mid‑50s% range) has lifted global risk‑free rates and US policy expectations. The move increases the discount rate applied to emerging market cashflows and raises the cost of dollar funding priced off US Treasuries and Fed expectations. Higher US yields transmit into African credit chiefly through duration and refinancing channels: long‑dated Eurobonds (10‑ to 30‑year) of higher‑beta sovereigns are most exposed as their present values fall faster.
Ghana and Zambia — which have longer external amortisation profiles and recurrent primary market sensitivity — face widened spread risk via higher US discount rates and higher rollover premia. Kenya’s 10‑year segment and longer maturities on Nigerian corporates with external coupons also carry duration risk given the higher US treasury curve. Currency and funding strains follow a stronger dollar impulse: an uptick in US yields tends to tighten dollar liquidity and push up cross‑currency basis, increasing the effective local cost of dollar debt for corporates and sovereigns with short foreign currency buffers. Lower reserve adequacy would amplify pressure on currencies with narrow FX stacks; credits with larger official financing lines or recent bond issuance may show relative resilience. The desk will watch two conditional points: whether the Fed futures repricing persists into the September meeting and whether US long yields break materially above the current range—if so, expect renewed spread widening concentrated in the long end of higher‑beta African curves.
