Global bond selloff ahead of ECB decision and US buybacks: Core yield repricing pressures long-dated African Eurobonds

Core sovereign yields moved higher sharply in European trade as dealers repositioned ahead of a widely expected ECB policy decision and reports of U. S. Treasury buyback activity. The move re-priced Bunds and Treasuries materially during the session, and market coverage linked the selloff to both ECB rate expectations and U. S. Treasury operations. Higher German and U. S.

yields transmit into African credit through the discount-rate channel and duration exposure. Long-dated Eurobonds — the 10–30 year part of the curve for higher-beta issuers such as Ghana and Zambia — are most exposed: higher core rates increase the present-value haircut on distant coupons and widen required spreads, while the immediate repricing raises hedging and cross-currency basis costs for external debt. Issuers that rely on short-dated external rollovers and hedged FX forwards (including Côte d’Ivoire and Egypt) face higher refinancing premia and dollar funding costs as dealer balance sheets re-price term funding. Compare the transmission to regional peers: higher core yields are a tougher shock for high-duration, externally funded credits (Ghana, Zambia) than for lower-duration or more domestic-funded issuers (South Africa, Morocco), where local policy rates and domestic investor depth blunt part of the pass-through. The desk will watch ECB communication and the size/timing of U. S. Treasury buybacks; a surprise to either point will steepen global curves further and amplify spread widening across 2028–2035 African maturities.
