Africa corporate debt market
Nigeria has emerged as Africa’s second-largest corporate debt market, accounting for 16 per cent of the continent’s outstanding corporate debt as of the end of 2025, according to the Organisation for Economic Co-operation and Development.
The finding places the country behind South Africa in the ranking of Africa’s biggest corporate borrowing markets and underscores Nigeria’s growing importance in the financing of businesses across the continent.
According to the OECD’s Africa Capital Markets Report 2026, South Africa accounted for about 30 per cent of Africa’s outstanding corporate debt, while Nigeria followed with 16 per cent.
Egypt accounted for 13 per cent, Mauritius nine per cent, Mozambique six per cent and Morocco five per cent.
Together, the six economies controlled about 80 per cent of Africa’s outstanding corporate debt at the end of 2025, demonstrating how heavily concentrated corporate borrowing remains across the continent.
But Nigeria’s position in the Africa corporate debt market tells a more complicated story than the headline ranking alone suggests.
While the country has one of the continent’s largest corporate financing markets, Nigerian businesses continue to operate in an environment characterised by high interest rates, limited access to affordable long-term funding and intense competition with government borrowing.
Nigeria takes 16% of Africa corporate debt market
The OECD estimated total outstanding corporate debt across Africa at about $211 billion in 2025.
This covered corporate bonds, syndicated loans and private credit.
Nigeria’s 16 per cent share places the country firmly among the most important players in the Africa corporate debt market.
However, the continental total remains relatively small when compared with the rest of the world.
Africa accounted for just 0.3 per cent of global outstanding corporate debt in 2025, even though the continent represented approximately 2.7 per cent of global gross domestic product.
The gap illustrates the underdevelopment of African capital markets.
In practical terms, many companies across the continent still struggle to raise long-term financing through bonds, private credit and other market-based instruments.
Instead, they rely heavily on commercial banks.
That reliance can become a serious problem when interest rates rise.
For Nigerian businesses, the cost of borrowing has become one of the biggest obstacles to expansion.
Companies require capital to purchase machinery, build factories, increase inventory, expand distribution networks and employ more workers.
But when credit becomes too expensive, many companies either reduce investment or abandon expansion plans altogether.
South Africa remains dominant
South Africa retained its position as Africa’s most developed corporate debt market.
The OECD said companies headquartered in South Africa had about $63 billion in outstanding corporate debt by the end of 2025.
That made the country by far the largest individual contributor to the Africa corporate debt market.
Nigeria’s second-place position is therefore significant, but the gap between the two markets remains substantial.
Egypt, which once competed closely with South Africa in corporate borrowing, has seen its relative share fall considerably.
According to the OECD, Egyptian companies accounted for around 30 per cent of Africa’s corporate debt in 2010.
By 2025, that share had fallen to 13 per cent.
The organisation said the shift reflected a contraction in Egypt’s corporate debt stock rather than exceptional growth elsewhere.
The changing ranking also highlights how rapidly financing conditions can shift across African economies.
Currency movements, inflation, interest rates, political stability and access to international finance can all influence corporate borrowing.
Africa’s corporate bond market remains shallow
Another major finding is the limited development of corporate bond markets.
Syndicated loans accounted for about 81 per cent of outstanding African corporate debt in 2025.
Corporate bonds accounted for only about $35 billion.
The OECD said the real value of Africa’s corporate bond market had declined sharply compared with its 2015 peak.
This is significant because developed corporate bond markets can provide businesses with alternatives to conventional bank loans.
Large companies can issue bonds directly to investors, pension funds, insurance companies and other institutions.
That gives businesses access to longer-term capital and can reduce pressure on banks.
But across much of Africa, including Nigeria, the corporate bond market remains relatively narrow.
The Africa corporate debt market therefore continues to depend heavily on syndicated loans and traditional banking relationships.
That structure can make businesses more vulnerable to changes in monetary policy.
When central banks increase interest rates to combat inflation, commercial lending rates typically rise.
Businesses then face higher financing costs.
High borrowing costs pressure Nigerian companies
Nigeria’s corporate financing environment has become particularly difficult because of high interest rates and substantial government borrowing.
When the Federal Government raises large amounts of money from the domestic debt market, it competes with private-sector businesses for available funds.
Government securities can also be attractive to banks and institutional investors because they are generally considered lower-risk assets.
That creates what economists describe as a crowding-out effect.
Rather than lending to manufacturers, agricultural businesses and other companies, financial institutions may choose to invest in government securities.
The result can be reduced credit availability for businesses.
This makes Nigeria’s 16 per cent position in the Africa corporate debt market particularly interesting.
The country has a large corporate debt stock, but access to affordable financing remains difficult for many businesses, especially small and medium-sized enterprises.
Large listed companies and multinational corporations generally have better access to banks, commercial paper and bond markets.
Smaller businesses often do not.
For them, financing may still come from personal savings, family networks, cooperatives, expensive short-term loans or informal lenders.

Nigeria’s public debt adds another dimension
The OECD findings also come at a time when Nigeria’s public debt has continued to rise.
Nigeria’s total public debt reached about ₦166.79 trillion as of June 30, 2026, according to figures cited in the report.
That was up from ₦159.35 trillion at the end of March 2026.
The increase amounted to about ₦7.44 trillion within three months.
Rising government borrowing has important implications for the private sector.
Public borrowing is not necessarily negative.
Governments borrow to finance infrastructure, budget deficits and development projects.
But when domestic borrowing becomes excessive, it can influence interest rates and reduce the volume of credit available to companies.
That relationship matters for the Africa corporate debt market, particularly in large economies such as Nigeria where governments and businesses compete for the same pool of domestic savings.
Nigeria’s commercial paper market offers alternative
Despite these pressures, Nigeria’s capital market has shown signs of increasing diversification.
Companies have increasingly used commercial paper to raise short-term funding.
Commercial paper allows companies to borrow directly from investors without relying exclusively on conventional bank loans.
It has become an increasingly important financing instrument for major Nigerian companies.
However, commercial paper is normally short-term.
It does not solve the larger challenge of providing businesses with affordable long-term financing.
Infrastructure, manufacturing, mining, housing and large agricultural projects often require capital that can be repaid over many years.
That is where corporate bonds, private credit and institutional investment become particularly important.
Developing those markets could strengthen Nigeria’s position within the Africa corporate debt market while also reducing dependence on commercial banks.
Africa sitting on $4.4tn capital pool
Perhaps one of the most important findings in the OECD report is that Africa may already possess significant financial resources that could support investment.
The OECD estimated that the continent has more than $4.4 trillion in domestic capital pools.
These funds are held across banks, pension funds, insurance companies, sovereign wealth funds, public development banks and central banks.
The challenge is mobilising more of that money into productive investment.
If even a larger proportion of pension and insurance assets were invested through well-regulated capital markets, African businesses could gain access to significantly more long-term financing.
The Africa corporate debt market could then become a stronger engine for industrialisation.
That money could support factories, electricity projects, housing, transport infrastructure, technology companies and agricultural processing.
But institutional investors also require credible regulation, transparent financial reporting and predictable investment environments.
Companies seeking capital must demonstrate that investors’ money will be protected.
Africa accounts for tiny share of global markets
The scale of Africa’s financing challenge becomes clearer when compared with global markets.
Despite its population, natural resources and economic potential, Africa accounted for only around 0.4 per cent of global market capitalisation in 2024.
The OECD described the continent’s capital markets as underutilised sources of long-term financing.
This has consequences for economic development.
Countries cannot rely indefinitely on government budgets and bank loans to finance industrialisation.
Modern economies require deep capital markets.
Businesses need the ability to raise equity and debt from a broad range of investors.
Infrastructure developers need long-term financing.
Pension funds need investable assets.
Individual investors require credible investment opportunities.
The stronger these connections become, the more effectively financial capital can be channelled into productive parts of the economy.
Corporate debt is not automatically bad
Nigeria’s large share of the Africa corporate debt market should also not automatically be interpreted as a sign that Nigerian companies are dangerously indebted.
Corporate borrowing can be healthy.
A company may borrow money to build a new factory, expand production, acquire equipment or enter new markets.
If the investment generates returns above the cost of financing, debt can contribute to economic expansion.
The real issue is the quality, cost and sustainability of borrowing.
Debt becomes dangerous when companies borrow at rates they cannot afford, use short-term debt to finance long-term projects or take loans without generating sufficient income to repay them.
That is why the structure of Nigeria’s corporate debt matters as much as its size.
A deeper market offering businesses access to bonds, private credit, pension capital and other long-term instruments could improve financing conditions.
SMEs remain largely outside sophisticated debt markets
Another major weakness is that much of Africa’s market-based corporate financing remains concentrated among large businesses.
The OECD acknowledged that access to corporate debt markets is still largely confined to bigger companies.
This presents a major problem for Nigeria.
Small and medium-sized enterprises account for a substantial share of economic activity and employment.
Yet many SMEs cannot issue corporate bonds or access syndicated loans.
Their financing needs may be relatively small compared with large corporations, but collectively they represent an enormous part of the economy.
For Nigeria to fully benefit from its growing position in the Africa corporate debt market, financing must become more inclusive.
Credit must reach manufacturers, traders, farmers, technology companies and service businesses that fall outside the traditional corporate elite.
What Nigeria’s ranking really means
Nigeria’s 16 per cent share gives the country an important place in Africa’s financial landscape.
It demonstrates the scale of Nigerian corporate activity and the country’s significance to continental finance.
But the ranking also exposes a contradiction.
Nigeria has Africa’s second-largest corporate debt market, yet many Nigerian businesses still describe access to affordable credit as one of their biggest challenges.
That suggests the next stage of development cannot simply be about increasing the amount of debt in circulation.
It must focus on improving access, reducing borrowing costs and lengthening the maturity of available financing.
Nigeria also needs a stronger corporate bond market, deeper private credit activity and greater participation by institutional investors.
Turning debt into economic growth
The real importance of the Africa corporate debt market lies not in how much companies owe but in what borrowed money produces.
If debt finances factories, electricity infrastructure, agricultural processing, housing, technology and job creation, it can support economic growth.
If borrowing simply becomes increasingly expensive without generating productive investment, it can weaken companies and increase financial risk.
Nigeria’s position as the continent’s second-largest corporate debt market therefore represents both an achievement and a challenge.
The country has demonstrated the scale required to become a leading African financial market.
What it now needs is depth.
Businesses require more financing options.
Investors need greater confidence.
Capital markets need to become more accessible.
And long-term domestic savings need to be connected more efficiently with productive businesses.
With Africa holding an estimated $4.4 trillion in domestic capital pools, the money exists.
The bigger question is whether countries such as Nigeria can build the institutions, markets and confidence necessary to channel more of it into companies capable of creating jobs, infrastructure and sustained economic growth.
For Nigeria, holding 16 per cent of the Africa corporate debt market is therefore only part of the story.
The more important test is whether that market can evolve from a measure of how much companies borrow into a platform for financing the country’s long-term development.
