US 10-year near 5%: Long-dated African Eurobonds most exposed as term premium rises
A global bond selloff pushing US 10‑year yields toward 5% raises the discount rate and term premium, concentrating downside on long-dated African Eurobonds and increasing rollover costs for dollar‑borrowers, with issuance and secondary‑market liquidity at risk.

Desk brief
Global bond markets sold off and the US 10-year yield moved toward the 5% area on Sept. 11, driven by higher oil and renewed inflation concerns ahead of US CPI and a Fed decision. The move raises the global risk‑free discount rate and the term premium investors use to price long-duration assets. Higher US yields transmit to African sovereign and corporate credit primarily through two channels.
First, the discount-rate effect re-prices long-dated African Eurobonds more than short-dated paper — credits with large long-dated buckets (for example, longer-dated Ghana or South Africa Eurobonds and long‑dated corporate names) will see price and spread sensitivity amplified by higher US rates and increased duration-driven volatility. Second, a higher US risk-free rate widens emerging-market sovereign spreads, increases the external cost of rollovers for dollar borrowers and reduces issuance appetite in the primary market, squeezing liquidity in secondary markets and raising refinancing premia for upcoming external amortisations. Compared with regional peers, commodity exporters with natural FX buffers (Angola, Nigeria—noting Nigeria’s fuel-import and subsidy complexity) are less outright vulnerable to a pure term‑premium move than importers and highly externalised sovereigns that rely on fresh Eurobond access; low-reserve or high-external-debt sovereigns face a steeper cost-of-capital shock. The desk will monitor secondary-market spread moves on existing long-dated African Eurobonds and near-term primary issuance windows as the Fed decision and US CPI data crystallise investor positioning.
