African policymakers, regulators, investors and development-finance institutions are examining how credit ratings shape the cost and availability of capital as the continent seeks to deepen domestic financial markets and mobilise more of its own savings for infrastructure and sustainable development. The discussions are taking place at the second Africa Annual Conference on Credit Ratings in Port Louis, Mauritius, from October 5 to 6, bringing together the United Nations Economic Commission for Africa (UNECA), the African Peer Review Mechanism, the United Nations Development Programme, AfriCatalyst and financial-market stakeholders around the theme of developing African capital markets and rechanneling Africa’s capital.
The conference comes as African governments face competing demands for financing infrastructure, energy, climate resilience and social investment while fiscal space remains constrained in many economies. UNECA said the meeting is examining how credit-rating systems influence investment decisions and the cost of capital, alongside measures to improve transparency in risk assessment and strengthen African financial markets.
The issue is important because a sovereign credit rating is not confined to government borrowing. It can influence how international investors price government bonds, infrastructure projects and corporate debt, while also affecting the financing conditions available to banks and companies operating in the same market. For countries seeking to attract long-term capital into power systems, transport networks, water infrastructure and low-carbon industries, the cost of capital can determine whether a project is financially viable.
According to the African Development Bank’s 2026 African Economic Outlook, African issuers face an additional risk premium of about 2.9 percentage points even after accounting for macroeconomic fundamentals and sovereign credit ratings. The bank said the additional premium raises effective discount rates for long-lived infrastructure and industrial projects, creating a disincentive for private investment.
That financing premium matters particularly for projects whose returns accumulate over decades. A solar plant, railway, transmission line or water system may require substantial capital before generating sufficient revenues, making financing costs a significant component of the final cost of infrastructure. Higher borrowing costs can therefore affect not only governments but also utilities, private developers and consumers.
The Mauritius conference is consequently focusing on a broader capital-market question: whether Africa can mobilise more domestic capital and retain a larger share of its financial resources for investment within the continent. UNECA said discussions will consider market liquidity, investment instruments, market infrastructure and access to local-currency financing, as well as the role of regional financial institutions and regulatory frameworks in mobilising domestic savings.
Local currency finance is particularly relevant because borrowing in foreign currencies can expose African governments and businesses to exchange rate risk. When a country’s domestic currency depreciates against the currency in which debt is denominated, the local currency cost of servicing that debt can rise even when the underlying project or government revenue has not changed proportionately. Developing deeper domestic bond markets can therefore provide an additional financing channel while reducing some of the currency mismatches associated with external borrowing.
The challenge is that domestic capital markets remain uneven across the continent. Larger markets such as South Africa, Egypt, Nigeria and Kenya have more developed financial systems, while smaller economies often face limited liquidity, a narrow investor base and fewer instruments through which pension funds, insurers and other institutional investors can deploy long-term savings.
For Africa’s sustainable finance agenda, these constraints have practical consequences. Climate adaptation, renewable energy, resilient agriculture and water infrastructure require capital with relatively long investment horizons. If domestic pension and insurance assets can be channelled more effectively into productive investments, they could provide an additional source of financing alongside development banks, commercial lenders and international climate funds.
The conference is also considering the relationship between credit ratings and technology. UNECA said participants are examining how artificial intelligence, data and financial technology could be applied to credit ratings and capital market development, while considering the opportunities and risks that these tools create for African financial systems.
Better data could potentially improve the information available to investors and rating agencies, particularly in markets where economic statistics, corporate disclosures or infrastructure-performance data are less comprehensive. But the use of technology does not remove the underlying institutional requirements. Reliable public accounts, transparent debt information, credible regulatory systems and consistent disclosure remain essential if risk assessments are to command investor confidence.
The debate therefore extends beyond whether ratings accurately capture individual countries’ risks. It also concerns the quality of the information and institutions on which those assessments are based. African policymakers have increasingly argued that country-specific conditions, development structures and investment risks can be misunderstood when they are assessed using methodologies developed largely around more mature financial markets.
The African Development Bank has similarly linked the continent’s financing challenge to risk perception. The bank has cited estimates that African countries can face substantially higher costs of capital than other regions and has supported reforms aimed at strengthening African risk assessment and risk-sharing mechanisms. In 2026, the bank has also backed the New African Financial Architecture for Development, including a proposed Pan-African guarantee mechanism intended to lower financing costs and mobilise investment.
But improving ratings alone would not resolve Africa’s financing constraints. Credit assessments are ultimately only one part of the investment equation. Investors also consider debt sustainability, inflation, exchange rate stability, governance, political risk, regulatory predictability, infrastructure quality and the ability of projects to generate reliable revenues.
That distinction is important for governments seeking to use sustainable finance instruments. Green, social and sustainability bonds, for example, can broaden the pool of capital available for development priorities, but their effectiveness depends on credible frameworks, eligible project pipelines, transparent use-of-proceeds reporting and investor confidence in the issuer. The African Development Bank itself operates a Sustainable Bond Framework and has used green and social bond markets to finance development priorities.
For African governments, deeper domestic capital markets could also change the relationship between public finance and private investment. Stronger local markets can provide banks and institutional investors with more instruments, while giving governments alternatives to relying predominantly on external borrowing or development assistance.
Yet mobilising domestic capital will require more than creating securities. Pension funds, insurers, banks and other institutional investors need investable assets, appropriate regulatory frameworks and sufficient market liquidity. Governments also need to maintain fiscal credibility so that domestic borrowing does not crowd out private investment or push financing costs higher.
The stakes are particularly high as African economies attempt to finance the infrastructure required for urbanisation, industrialisation and the energy transition. Electricity grids, transport systems, digital infrastructure and water networks require large upfront investments, while climate change is increasing the need for adaptation and resilience spending. The ability to finance those assets at sustainable costs will influence the pace and quality of economic development.
This is where credit ratings become part of a much larger governance issue. Transparent public finances, reliable economic data, stronger institutions and effective regulation can improve the information available to markets while also strengthening the foundations on which domestic investment depends. Conversely, weak disclosure and limited market infrastructure can raise uncertainty even where underlying economic opportunities are substantial.
UNECA’s conference therefore places credit ratings within a wider effort to strengthen African capital markets rather than treating them as an isolated technical issue. The discussions in Mauritius are bringing together governments, regulators, investors, rating agencies and development-finance institutions to consider how domestic savings can be better connected to productive investment and how financial-market infrastructure can support longer-term development.
For Africa, the test will ultimately be whether reforms in risk assessment and capital markets translate into lower financing costs, deeper local investment and greater capacity to fund productive assets. A more developed financial system would not eliminate fiscal or project risks, but it could give African governments and businesses more options for managing them.
As countries confront simultaneous demands for economic growth, climate resilience, energy security and infrastructure expansion, the question of how Africa is assessed by capital markets is becoming inseparable from how the continent finances its development. The Mauritius discussions put that connection firmly back on the policy agenda, with domestic capital mobilisation emerging as an increasingly important complement to external finance.
