Nigeria Eurobond Amortisation Load: Concentrated $6.4bn Principal Repayments Raise Refinancing Premium Risk

World Bank analysis shows Nigeria faces approximately USD 6.4bn of sovereign Eurobond principal maturities across 2024–2030. That concentrated external amortisation profile raises the country’s refinancing needs and places upward pressure on the sovereign’s term structure via increased roll‑over risk. The mechanism runs through external debt service and reserves: concentrated principal outflows increase gross financing requirements, which — absent offsetting balance‑of‑payments improvements or stepped‑up official financing — elevate the refinancing premium demanded by international investors.

The parts of Nigeria’s curve with the highest upcoming principal amortisation (the belly and near‑to‑medium dated tranches where large maturities cluster) are most vulnerable to spread widening and higher yields as investors price in execution risk and potential demand for larger coupons. Currency transmission is also material: greater external net outflows can tighten FX reserves, raising pressure on the naira and increasing the local‑currency cost of servicing any remaining foreign‑currency liabilities.

Compared with regional peers that have more evenly spread amortisation or stronger access to official backstops, Nigeria’s concentrated profile is a distinctive source of vulnerability. Sovereigns with flatter external schedules avoid the same short‑term refinancing cliff, meaning investor focus will bifurcate between credits with manageable rollovers and those forced into repeated large tap or replacement transactions.

The conditional dynamic to monitor is whether Nigeria secures clear, credible external funding assurances or smooths the maturities curve; absent such intervention, expect the belly of its Eurobond curve to carry a persistent refinancing premium.
