This session will highlight how collaboration and co-operation can help scale the mobilisation of private finance, by showcasing three concrete examples of effective platforms & initiatives. These enrich the blended finance ecosystem by reducing information asymmetries, increasing operational efficiencies, and fostering greater collaboration. The aim is to share key insights on and from these solutions, to increase co-operation around them and consider ways to replicate them.

The high-level panel will provide the opportunity to reflect on the current development finance architecture. It will address the challenges that hinder the mobilisation agenda and the effective use of blended finance. The discussion will focus on creating actionable momentum.

In collaboration with ENVIRONET Unlocking finance from private sources for adaptation is essential to contribute to scaled-up climate financing, and blended finance constitutes a key approach for achieving this. This session will discuss how to collectively scale financing for adaptation, considering massive needs, existing efforts and respective potential pathways. It will leverage the upcoming OECD Blended Finance Guidance for Climate Change Adaptation, that provides concrete recommendations for development finance actors to better design blended finance interventions and mobilise private finance towards key adaptation needs and priorities. More specifically, the Guidance focuses on framing the role of blended finance for adaptation in key adaptation sectors, and explores the use of traditional and innovative financing instruments with the potential to amplify the resources towards climate change adaptation.

By linking scale with impact, green, social, sustainability and sustainability-linked (GSSS) bonds hold immense potential for mobilising private finance towards sustainable development. Yet issuances are largely not happening in the countries or regions that have the greatest financing needs, and which could therefore benefit the most from these instruments. At the same time, investors are often reluctant – or disincentivized – from investing in issuances from developing countries. The session will explore the incentives and disincentives for both issuers and investors to enter the GSSS bond market. The discussion will focus specifically on the role that development actors and other key stakeholders can play in overcoming the barriers and increasing the attractiveness of GSSS bonds, to ultimately scale up the use of these instruments in the mobilisation of private finance.

As the world faces a convergence of crises, MDBs’ resources are in greater demand than ever. Calls to reform the international financial architecture underscore the urgency. MDBs not only need additional resources, but they also need to use these resources more effectively. This session sets out the role of the MDBs in mobilising private capital in developing countries, by outlining their current role in the development finance architecture. It will highlight the importance of the MDB reform agenda – and how to ensure that pathways to deliver reform live up to their potential and mobilise private finance at scale. It will also dive into how MDBs can more effectively use their balance sheets to mobilise more private finance.

Lack of data is a key barrier that prevents private capital from flowing to emerging markets and developing economies (EMDEs). The session will focus on the challenges and opportunities of demystifying emerging markets through data to help investors better price risk and make data a lever of private investment. It will focus on the specific data needs of the private sector for different instruments and via different mobilisation channels. The discussion will also zoom in on potential pathways ahead in ensuring that these needs are met – especially by outlining the roles that different market players can play. Finally, it will highlight the role that transparency can play in making lending decisions and managing exposure risks, thereby attracting private investors, and ensuring regulatory compliance.

The development community agrees on the need to address conflicts and crises, as global security is a prerequisite to sustainable development. This session will dive into the role and potential of blended finance in conflict and crises-affected contexts, with focus on Ukraine. It will outline the current landscape of blended finance in these contexts and highlight the main challenges and opportunities for development finance providers to unlock additional resources for reconstruction and development. In particular, the session will explore how international development actors can better implement blended finance instruments and approaches to address these crises and build resilience.

This session will highlight how collaboration and co-operation can help scale the mobilisation of private finance, by showcasing three concrete examples of effective platforms & initiatives. These enrich the blended finance ecosystem by reducing information asymmetries, increasing operational efficiencies, and fostering greater collaboration. The aim is to share key insights on and from these solutions, to increase co-operation around them and consider ways to replicate them.

The OECD Development Assistance Committee (DAC) approved the five Blended Finance Principles in 2017 and developed a Guidance for each of them in 2020. The Blended Finance Guidance is currently being updated to ensure that it remains relevant in a changing development finance context, and that it is fit-for-purpose in mobilising private finance at scale. This session will dive into the latest knowledge from the update of the OECD Blended Finance Guidance. It will highlight what has worked and what has not worked so well in the blended finance landscape, and how international development actors can improve the effective and efficient use of blended finance interventions to mobilise private finance at scale.

Scaling local currency financing solutions remains crucial for mitigating exchange rate risks, strengthening domestic financial markets and in enhancing economic resilience in developing countries. This session sets out to highlight the obstacles that hinder effective local currency financing, particularly relating to the development of local financial markets. Panellists will discuss solutions, current and potential, that development actors can deploy to overcome these obstacles and what this would mean for investors. The session will specifically explore the role that DFIs and MDBs can have in providing blended finance solutions to improve access to local currency funding, and to support policies that foster more resilient local financial markets.  

This session will dive into the potential of development finance to unlock private finance for biodiversity in developing countries. It will explore the challenges and opportunities of the private sector to support biodiversity-related projects (e.g. conservation, agroecology, nature-based solutions), and tap into the role of development co-operation providers in scaling-up their efforts. It will also seek to better understand existing policy levers and financial mechanisms to mobilise private finance for biodiversity action. The aim of this session is to reflect on evidence, policies and action needed to scale financing for biodiversity, including through blended finance.

Regulatory barriers can create challenges and uncertainties that deter foreign investors. This session will focus on the regulatory barriers that hinder private sector finance from flowing to developing countries, including in pivotal sectors such as climate finance. It will build on and explore the effects – following the implementation of Basel III, Solvency II and other major regulations – on lending practices and cross-border investments from global private sector actors into emerging markets and developing countries, with particular attention on sustainability and climate-related regulations.  

Understanding how best to leverage structured funds across different sectors and geographies is crucial to ensuring that resources are allocated efficiently, concessionality is minimised, and the commercial viability of these projects can be maintained in high-risk markets. This session will address the key challenges to establishing structured blended finance funds. Through a series of case studies spanning various sectors and regions, the session will look to offer insights into setting appropriate concessionality levels and achieving optimal risk-return profiles across different investment tranches within these collective investment vehicles.  

Investors tend to favour traditional markets for their investments. The session will dive into what factors are preventing them from investing in emerging markets. It will explore concrete solutions to overcoming these barriers – including, for example, the aggregation of small-scale projects into deals large enough for global investors, and the role of local capacity building and technical assistance in supporting local solutions.

For blended finance to be a development tool, and to guarantee its integrity, we need to ensure that it generates development impact for the final beneficiaries in emerging markets. This session will explore how much we (don’t) know about the development impacts of blended finance, how practitioners assess them ex-ante and ex-post, and how development finance providers integrate an impact lens when designing blended finance transactions.

Prime Minister Mia Mottley of Barbados will deliver a speech on the urgent need to mobilize resources and strengthen partnerships for transformative global change. Highlighting the critical interplay between public and private actors, she will outline actionable strategies to step up ambitions and drive significant progress. As we approach FfD4, her forward-looking remarks challenge stakeholders to rethink collaboration, innovate boldly, and raise the game to tackle pressing global challenges.

For blended finance to work effectively, it takes a village. This session will build on the benefits and challenges of achieving increased co-operation among different development finance providers. It will delve into how bilateral and multilateral donors, DFIs and private sector actors can work in a more collaborative and coordinated way to develop an investment and mobilisation-friendly architecture. The goal of this session is to take us from ambition to action. What does blended finance of the future look like? How do we get there?

The concluding remarks will highlight the main takeaways from the CoP-PF4SD Conference 2025 and provide key recommendations on the next steps for the development financing community to bring mobilisation of private finance at scale towards 2030 and beyond.
