The African Premium in Fixed Income Markets: An Empirical Analysis of Sovereign Bond Spreads and Money Market Dynamics

Mue, Kelvin (2026): The African Premium in Fixed Income Markets: An Empirical Analysis of Sovereign Bond Spreads and Money Market Dynamics.

Abstract

This paper seeks to provide an analysis of the "African premium”, that is, the excess yield or cost that African sovereign and corporate issuers pay relative to comparable emerging market peers. Drawing from academic literature, market data, and institutional reports spanning 2008-2026, we document that African sovereigns systematically pay higher borrowing costs than justified by fundamental risk factors alone. In 2018, African Eurobond yields averaged 6.0%, which equated to a 50-basis point premium compared to the 5.5% emerging market average, coupled with a 200-basis point premium compared to the 4.0% Asia-Pacific average. On careful observation, my analysis has shown that as important as macroeconomic factors such as debt ratios, growth prospects, and inflation rates are, along with credit rating, governance, and global factors, they do not explain the high borrowing costs for African countries. This unexplained component suggests the presence of a so-called "prejudice premium" or structural mispricing, potentially costing African economies billions annually in excess interest payments. The African fixed income market has experienced tremendous growth, with Sub-Saharan Africa Eurobond issuance growing from less than $1 billion in 2008 to $18 billion in 2025. However, ongoing challenges include low market liquidity, investor bases, bond maturities, as well as exposure to global financial shocks. Notwithstanding, as of mid-2025, a sovereign spread crisis, as measured by distressed levels above 1,000 basis points, did not affect any African country. This is a milestone not achieved since 2015. The policy implications relevant to this paper thereafter relate to issues like strengthening macroeconomic fundamentals, better governance, better institutions, better debt transparency, better development of local currency markets, and better addressing issues like information asymmetries through initiatives like the Africa Credit Rating Agency (AfCRA), which was recently established on January 27th 2026. These measures could potentially substantially reduce the African premium and lower financing costs for governments and corporations across the continent.
