U.S. Services Growth Reaccelerates: Higher-For-Longer Risk Pressures African External Duration
A stronger-than-expected U.S. services PMI reinforces the risk that monetary easing is delayed, keeping global discount rates elevated. Long-dated Ghanaian and Kenyan Eurobonds are most exposed through duration and refinancing premia, while easing output-price inflation provides a limited counterweight to the rates signal.

Desk brief
The U.S. flash Services PMI rose to 56.8 in August from 54.6 in July, above the roughly 54.0 consensus and marking the strongest expansion since December 2024. The Composite Output Index reached 56.0 from 54.5, its strongest level since April 2022, as services growth offset slower manufacturing activity. Input costs continued to rise, although output-price inflation eased and business confidence improved for a third consecutive month. The combination points to resilient demand alongside persistent cost pressure rather than a clean disinflation signal.
The rates channel runs through expectations for near-term U.S. monetary easing. Stronger services activity can keep Treasury yields and the global risk-free discount rate elevated, placing the greatest pressure on long-dated African sovereign Eurobonds and corporate external debt. For Ghana and Kenya, the mechanism is higher required yield compensation on duration and a potentially larger refinancing premium; African currencies also face pressure if elevated U.S. rates support global dollar funding costs and reduce portfolio inflows.
The moderation in U.S. output-price inflation limits the case for an unchecked rates shock, but rising input costs preserve upside risk to U.S. yields. This creates a differentiated exposure across African markets: the long end of Ghanaian and Kenyan Eurobond curves is more sensitive to the discount-rate channel than shorter maturities, while local-currency markets would face the additional question of imported inflation and currency pass-through if dollar funding conditions tighten.
The conditional signal for African credit is whether resilient services demand is followed by renewed pressure in U.S. inflation measures or instead by further easing in output-price inflation. The former would extend duration and currency headwinds for African external borrowers; the latter could reduce the intensity of the Treasury-yield transmission without removing refinancing risk created by elevated global rates.
