Mozambique is putting sovereign creditworthiness and innovative financing at the centre of its efforts to mobilise capital for climate and sustainable development, with the government and the United Nations Economic Commission for Africa (UNECA) convening a three-day workshop in Maputo from September 21 to 23 to examine how the country can strengthen investor confidence, improve access to climate finance and deploy instruments ranging from thematic bonds to debt-for-climate swaps and biodiversity credits. The discussions come as Mozambique faces severe debt pressures that constrain the fiscal space available for infrastructure, resilience and other development priorities.
The workshop, organised under UNECA’s project on innovative finance, is focused not simply on identifying new funding instruments but on the institutional conditions required to use them effectively. According to UNECA, the discussions are examining sovereign credit ratings, debt sustainability, investor engagement, data transparency and institutional credibility alongside the implementation of Mozambique’s National Climate Finance Strategy for 2025–2034.
That focus reflects a fundamental constraint facing many African economies: access to climate and development finance is shaped not only by the availability of projects but also by the cost and terms at which governments and companies can raise capital. Creditworthiness affects borrowing costs, investor confidence and access to capital markets. For Mozambique, improving those conditions is particularly important because the country is simultaneously seeking resources for climate resilience while managing a debt position that international institutions continue to regard as fragile.
The IMF’s latest assessment places Mozambique’s external debt at high risk of debt distress and its overall public debt in distress. The assessment also says public debt is on an unsustainable path under unchanged policies, with debt-service arrears and continued reliance on costly domestic borrowing adding to the pressure.
Domestic debt is expected to become an increasingly important part of Mozambique’s financing structure. The IMF projects domestic debt could reach about 63% of GDP by 2030 under its baseline, while interest payments are expected to average about 5% of GDP over 2025–30. The assessment notes that the government’s medium-term debt strategy aims to extend domestic maturities, limit short-term borrowing and increase access to concessional external finance.
These constraints make the question of innovative finance more consequential. Instruments such as green or thematic bonds, blended finance and debt conversions can diversify funding sources, but they do not eliminate underlying fiscal risks. Their usefulness depends on the strength of the projects being financed, the terms of the transaction and the institutions responsible for managing proceeds and reporting results.
Mozambique’s National Climate Finance Strategy, approved in 2025, provides the policy framework for that effort. The strategy seeks to integrate climate considerations into fiscal systems and financial-sector regulation, strengthen institutional capacity and expand access to domestic and international climate finance. It also identifies instruments including grants, debt-for-climate swaps, climate-risk insurance and carbon credits as potential sources of funding.
The strategy therefore places climate finance within the wider financial system rather than treating it as a separate environmental funding stream. That distinction matters for Mozambique because climate-related risks have direct economic consequences. Cyclones, floods, droughts and coastal erosion can damage infrastructure, disrupt agricultural production and place additional pressure on public spending. Financing resilience is consequently linked to the government’s ability to protect existing assets and maintain economic activity.
UNECA’s workshop is also examining debt-for-nature and debt-for-climate swaps as potential tools for creating fiscal space while supporting environmental and climate investments. Such structures can potentially connect debt management with development objectives, but they require careful assessment of the underlying liabilities, replacement financing, fiscal savings and governance arrangements. UNECA says the workshop is considering their relevance to both fiscal resilience and environmental financing.
Biodiversity finance introduces another layer. Mozambique is exploring the conditions for developing high-integrity biodiversity credit markets, with UNECA highlighting the need for appropriate policy, institutional, governance and technical arrangements. The emphasis on market integrity is significant because nature-based financing depends on credible measurement, verification and clear rules over what is being financed and what outcomes are being claimed.
For investors, this makes institutional credibility as important as the availability of natural assets or climate projects. Mozambique has substantial exposure to climate and biodiversity risks, but converting those assets and needs into investable opportunities requires reliable data, clear regulations, credible financial structures and institutions capable of monitoring the use of capital.
The country is already strengthening parts of that infrastructure. The IMF says Mozambique has migrated its external debt to the CS-Meridian debt-management system and is working to incorporate domestic debt data, while continuing to publish annual and quarterly debt reports. The government has also committed to greater transparency around public-sector debt, including liabilities and guarantees involving state-owned enterprises.
Those reforms matter because innovative finance can become difficult to assess when public liabilities, guarantees or contingent obligations are not fully visible. Stronger debt data can give investors and development partners a clearer picture of sovereign exposure while allowing government institutions to assess the fiscal consequences of new financing before transactions are completed.
The same principle applies to climate investment. Mozambique’s climate-finance strategy calls for stronger coordination between public institutions, financial-sector actors and other stakeholders. UNECA’s workshop similarly seeks to clarify institutional roles across public finance, debt management, environmental governance, financial regulation, capital-market development and sustainable-development planning.
This coordination will be important if Mozambique is to move from identifying financing instruments to developing projects that can absorb capital effectively. A thematic bond, for example, requires a credible pipeline of eligible expenditure, clear use-of-proceeds rules and reporting systems. Blended finance requires projects capable of attracting commercial capital alongside concessional resources. Biodiversity credits require credible baselines and monitoring systems. Each instrument therefore places demands on public institutions beyond the initial financing transaction.
The broader challenge is that Mozambique needs investment while its fiscal position limits the scope for additional conventional borrowing. The IMF has said restoring debt sustainability will require fiscal consolidation, stronger revenue mobilisation, improved debt management and measures to reduce financing pressures. At the same time, the government is considering innovative financing mechanisms, including carbon credits and debt-for-development swaps.
This creates a narrow space in which climate finance must support development without adding unsustainable liabilities. For infrastructure, the distinction is particularly important. Roads, water systems, electricity networks and coastal infrastructure require long-term capital, but financing them through expensive short-term debt can transfer today’s investment needs into tomorrow’s fiscal constraints.
Mozambique’s experience also reflects a wider African financing challenge. Governments across the continent are looking for ways to reduce the cost of capital, attract private investment and increase access to climate finance while maintaining debt sustainability. UNECA’s Sustainable Debt Coalition, which is being introduced as part of the Maputo discussions, is intended to provide a platform for peer learning, technical cooperation and support around sustainable debt and climate-aligned financing.
The immediate significance of Mozambique’s workshop is therefore less about any single financing instrument than about whether the country can build the institutional and financial foundations needed to use several of them credibly. Stronger creditworthiness can improve the terms on which capital is accessed, while better project preparation and governance can determine whether that capital reaches productive infrastructure, climate resilience and natural-resource management.
As Mozambique moves through implementation of its 2025–2034 climate-finance strategy, the test will be whether innovative finance can complement, rather than substitute for, stronger fiscal management and domestic financial reform. For a country facing substantial climate exposure alongside debt constraints, the ability to mobilise capital will depend increasingly on the quality of its institutions, the transparency of its finances and the credibility of the projects presented to investors.
The Maputo discussions consequently place climate finance within a broader economic question: how can Mozambique finance the infrastructure and resilience it needs without deepening the vulnerabilities that already constrain its public finances? The answer will depend not on financial innovation alone, but on whether new instruments are supported by credible debt management, investable projects, transparent institutions and a financing strategy capable of linking climate priorities with long-term economic capacity.
