Keypoints:
- African local bond index gains 5.9 percent
- Zambia delivers 32.3 percent dollar return
- Annual domestic debt issuance nears $500bn
AFRICAN local-currency government bonds have outperformed major emerging-market debt benchmarks over the longer term, while an MCB Investment Management index has gained 5.9 percent in dollar terms this year as double-digit yields and currency gains draw attention to the continent’s rapidly expanding domestic debt markets.
Behind the rally lies a deeper shift in African public finance. Annual domestic debt issuance has more than tripled from about $150bn in 2010 to nearly $500bn in 2024, overtaking multilateral, bilateral and external market borrowing as the continent’s dominant source of new sovereign financing.
African bonds pull clear
Fresh market data provide a striking picture of the returns drawing investors towards African debt.
MCB Investment Management’s August 10 market review showed its African Local Currency Bond Index had climbed 5.9 percent in dollar terms since the beginning of 2026, with Zambia and Nigeria among the strongest-performing markets.
Zambian local-currency government debt delivered a 32.3 percent total dollar return, boosted heavily by the strengthening kwacha. The performance comprised a 14.1 percent bond return and an 18.2 percent foreign-exchange gain.
Nigeria recorded a 14.7 percent total dollar return over the same period, reflecting gains from both its domestic bond market and currency movements.
The longer-term comparison is even more pronounced.
MCBIM data, drawing on Bloomberg market indices, show African local-currency government debt generating a cumulative dollar return of roughly 65 percent between December 2017 and August 2026.
That compares with about 23 percent for emerging-market local-currency government debt, 25 percent for emerging-market hard-currency sovereign debt and 53 percent for US high-yield securities.
The figures help explain rising interest in African fixed income. But investors are being rewarded for accepting considerable inflation, currency, political and sovereign risks.
Double-digit yields draw investors
The attraction is particularly visible in nominal yields.
MCBIM’s August snapshot put Egypt’s 10-year local-currency government bond yield at about 21.4 percent, Nigeria’s at 17.2 percent, Zambia’s at 16.2 percent, Ghana’s at 15.3 percent and Kenya’s at 13.4 percent.
Morocco, by contrast, offered around 3.3 percent at the same maturity.
The enormous differences underline why African debt cannot be treated as a single investment class. Investors must navigate markedly different inflation trajectories, fiscal positions, currencies and political conditions.
Zambia illustrates the potential upside. Its local bond market has emerged as one of 2026’s strongest performers, extending the recovery Africa Briefing examined in Zambia’s powerful local bond rally.
Nigeria is also attracting domestic investors even as Abuja keeps open the option of raising funds internationally. The Debt Management Office has begun selecting transaction advisers for a possible 2026 Nigerian Eurobond.
Africa’s debt is moving home
The bigger story is structural.
The African Debt Database, compiled by researchers from institutions including the Geneva Graduate Institute, World Bank, Kiel Institute and UN Economic Commission for Africa, tracks more than 50,000 government loans and securities across all 54 African countries.
Those instruments represent more than $6.3tn in commitments between 2000 and 2024.
Crucially, the researchers found that annual domestic debt issuance surged from roughly $150bn in 2010 to nearly $500bn in 2024.
The distinction matters. The $500bn figure refers to new domestic debt issued during the year, not the total stock of outstanding African domestic debt.
Domestic markets have nevertheless become the continent’s largest source of new sovereign financing, marking a significant shift away from historic dependence on foreign creditors.
The change follows years of disruption in international capital markets. Higher global interest rates, stronger foreign currencies and reduced access to cheap external funding pushed governments towards their own domestic investors.
The IMF says most public debt in sub-Saharan Africa is now domestic, a major reversal from the region’s traditional reliance on foreign-currency borrowing.
Africa Briefing has previously highlighted the scale of capital already sitting within the continent. More than $2tn in non-bank African domestic capital pools could potentially support investment if stronger financial systems connect long-term savings with productive projects.
High returns come at a price
For investors, double-digit yields can look compelling.
For finance ministries, however, those same yields represent expensive borrowing.
The IMF estimates that the median sub-Saharan African country issued domestic debt at an average interest rate of 8.8 percent in 2024. In several markets, domestic borrowing can therefore cost considerably more than concessional finance.
The African Debt Database finds that domestic bonds and Treasury bills are among the most expensive sources of sovereign finance on a nominal basis, with rates regularly exceeding 10 percent. The average cost of domestic bonds reached 12.84 percent in 2024.
There is another problem: maturity.
Domestic securities are often shorter dated than external loans, forcing governments to return to markets regularly to refinance existing obligations.
That creates rollover risk, particularly when inflation, currency weakness, political instability or deteriorating fiscal conditions suddenly push yields higher.
Ghana shows how challenging that adjustment can become.
Following its domestic debt restructuring, the country relied heavily on short-term Treasury bills while attempting to rebuild market confidence through payments including the $910m domestic debt interest settlement.
The IMF said Ghana’s average outstanding maturity remained below three months as of November 2025.
Banks absorb more sovereign risk
Moving debt home also changes who carries the risk.
Banks are among the largest buyers of government securities across many African economies.
That provides governments with a more dependable domestic funding base and reduces some exposure to dollar and euro exchange-rate shocks. But it also means more sovereign risk is being concentrated inside domestic financial systems.
The IMF has warned that the sovereign-bank nexus is expanding faster in sub-Saharan Africa than anywhere else, particularly in lower-income economies.
If governments experience severe financial stress, banks holding large portfolios of sovereign securities can suffer losses. If those banks subsequently require public support, pressure can feed back into government finances.
Heavy sovereign borrowing can also absorb liquidity that might otherwise flow to businesses, infrastructure projects and households.
That makes the current rally something of a paradox.
African domestic debt markets are becoming deeper, more liquid and more investable just as governments are becoming increasingly dependent on them.
What happens next?
The investment case remains compelling in selected markets.
Inflation has moderated in parts of the continent, currencies have strengthened in several economies and some governments are rebuilding credibility after years of debt distress.
But high yields do not amount to risk-free returns.
Currency depreciation can quickly erase gains for foreign investors, while fiscal deterioration can drive bond yields higher and prices lower.
For African governments, the more consequential question is whether deeper domestic capital markets become a durable source of development finance or simply another expensive mechanism for repeatedly refinancing public debt.
Greater reliance on local currencies could ultimately make African economies more resilient by reducing exposure to sharp dollar and euro movements.
But that will depend on governments extending debt maturities, broadening the investor base, strengthening fiscal credibility and ensuring sovereign borrowing does not overwhelm domestic banks or crowd out productive private investment.
Africa’s local bond rally may be grabbing global investors’ attention.
The more important transformation is that Africa’s sovereign debt market is increasingly moving home.
