The European Commission has adopted two new regulatory measures requiring credit rating agencies registered in the European Union to explain more clearly how environmental, social and governance (ESG) factors influence corporate credit ratings and outlooks, a move that could affect how African governments and businesses are assessed by international capital markets. Announced on November 9, the measures will require agencies to identify material ESG considerations behind rating decisions, disclose more information about their methodologies and demonstrate how those methodologies are validated. For African borrowers seeking international investment, the changes could increase scrutiny of climate exposure, governance standards and the quality of corporate and public-sector data used in credit assessments.
The measures amend the EU’s Credit Rating Agency Regulation and its technical standards governing rating methodologies. Under the new requirements, agencies will have to highlight ESG factors prominently in rating reports or announcements whenever those factors materially influence a credit rating, outlook or change in either. They must also explain why the factors were considered relevant to creditworthiness and how they were incorporated into the assessment.
The rules extend beyond disclosure of the final rating. Credit rating agencies will be expected to provide greater detail on the methodologies, models, assumptions and data sources underpinning their assessments. Their internal review processes will also have to validate the methodologies and key assumptions used, with checks on whether the underlying data is complete, accurate and appropriate.
According to Environment+Energy Leader, the regulations follow technical advice from the European Securities and Markets Authority (ESMA), which had identified a lack of transparency in how rating agencies incorporated sustainability risks that could affect credit quality. The European Commission’s approach is intended to make the relationship between ESG exposures and creditworthiness more visible to investors and rated entities.
The distinction between credit ratings and standalone ESG scores is important. The new measures concern credit ratings, which assess an issuer’s ability to meet its financial obligations, rather than separate ESG ratings that evaluate sustainability performance. The EU’s ESG Ratings Regulation, which applies from July 2026, governs the activities of ESG rating providers through a separate framework.
Although the new credit rating requirements apply to agencies registered in the EU, their implications could extend beyond European markets. International rating agencies assess governments and companies across Africa, and their opinions influence investor decisions, borrowing costs and access to international debt markets. African issuers that rely on European and other international investors may therefore face growing expectations to provide credible information on how climate, environmental and governance risks affect their financial position.
The timing is significant for a continent seeking to expand access to long-term capital while addressing substantial infrastructure and development financing needs. The Organisation for Economic Co-operation and Development’s (OECD) Africa Capital Markets Report 2026 found that outstanding market based corporate debt in Africa reached $211 billion at the end of 2025, equivalent to only 0.3% of global corporate debt, despite the continent accounting for 2.7% of global gross domestic product.
The market remains concentrated and heavily dependent on syndicated lending. According to the OECD, syndicated loans represented 81% of outstanding African corporate debt in 2025, while corporate bonds amounted to approximately $35 billion, 44% below their inflation-adjusted 2015 peak. Six countries: Egypt, Mauritius, Morocco, Mozambique, Nigeria and South Africa, accounted for 80% of outstanding corporate debt.
These figures illustrate the limited range of financing options available to many African companies. As governments and businesses seek to attract international capital for energy, transport, manufacturing and other infrastructure projects, the transparency of credit assessments can influence how investors compare risks across markets. More explicit disclosure of ESG factors could help investors distinguish between financial risks arising from weak governance, environmental liabilities, climate exposure and other operational vulnerabilities.
For example, a company’s exposure to flooding, water shortages or extreme heat can affect production, insurance costs, asset values and debt repayment capacity. In extractive industries, environmental liabilities and community disputes can lead to regulatory penalties, operational interruptions and additional expenditure. In the financial sector, governance weaknesses and inadequate oversight can affect asset quality and institutional stability. These issues can become credit risks when they materially affect an issuer’s capacity to meet its obligations.
For African governments, climate-related risks can also influence sovereign creditworthiness through their effects on public expenditure, economic output and revenue collection. Droughts can reduce agricultural production and increase food import costs, while floods can damage public infrastructure and require governments to redirect budgets towards reconstruction. Where such shocks coincide with high debt service obligations, the pressure on public finances can increase.
The United Nations Development Programme has previously identified concerns about how international credit rating methodologies assess African sovereign risk. Its 2025 report, Sovereign Credit Ratings: Perspectives for Africa’s Development, examined issues including foreign currency bias, insufficient consideration of informal economic activity and the treatment of African risk in global rating assessments. The report also argued that ratings influence not only access to capital markets but the cost at which African countries can borrow.
The EU’s new disclosure requirements do not directly resolve these wider concerns about the treatment of African borrowers. However, requiring rating agencies to explain which ESG factors influence their assessments could provide governments and companies with more information about how environmental and governance exposures affect credit decisions. Greater transparency may also give issuers a clearer basis for challenging inaccurate assumptions or improving the information they provide to investors.
The benefits will depend partly on the availability and reliability of African data. Many companies, particularly smaller businesses, have limited capacity to collect and report consistent information on emissions, resource use, labour practices, climate exposure and governance controls. Public institutions also face gaps in environmental data, climate risk modelling and the measurement of fiscal exposure to natural hazards. Where data is incomplete, rating agencies may rely on estimates, regional benchmarks or other proxies that do not fully reflect the circumstances of individual borrowers.
This presents a practical challenge for African financial institutions and businesses seeking to access international capital. Stronger ESG disclosure expectations could increase the cost of compliance, particularly for smaller issuers without dedicated sustainability reporting teams. At the same time, better internal data systems could help companies identify risks earlier, strengthen financial planning and demonstrate their capacity to manage environmental and governance exposures.
The OECD’s assessment of African capital markets also points to wider institutional constraints. Regulatory quality, rule of law, exchange rate stability and the development of domestic pension funds remain important conditions for deeper corporate bond markets. Only 17% of corporate debt issued in Africa in 2025 was denominated in local currency, leaving many borrowers exposed to exchange rate movements that can increase repayment costs.
Consequently, improved ESG transparency alone will not make African companies more creditworthy or resolve the structural barriers to financing. The availability of reliable financial information, credible governance systems, stable macroeconomic conditions and stronger domestic capital markets will remain central to attracting long-term investment. The new rules could, however, make the relationship between these factors and credit assessments more visible.
For African regulators, the developments also raise questions about how domestic disclosure frameworks and supervisory practices interact with international standards. Alignment with emerging global requirements could help reduce inconsistencies in information provided to investors, although implementation will need to reflect the size and capacity of local markets. Smaller companies may require proportionate reporting approaches and technical support to avoid compliance costs becoming another barrier to accessing finance.
The European Commission’s delegated regulations will enter into force 20 days after publication in the Official Journal of the European Union and will apply 12 months later. Until then, the measures remain subject to the applicable scrutiny process by the European Parliament and the Council.
For African governments and companies, the significance of the changes lies in how international financial markets increasingly connect environmental and governance exposures with assessments of credit risk. As the continent seeks to mobilise capital for infrastructure, energy and industrial development, the ability to demonstrate credible financial, environmental and governance performance could become increasingly important in determining how investors price risk and allocate funding.
