With development progress under increasing pressure and public budgets facing constraints, the need to attract more private capital aligned with sustainable development is growing.

The updated OECD Development Assistance Committee (DAC) Blended Finance Guidance offers a clear and practical framework to improve the quality, scale, and impact of blended finance. Building on the original 2017 Principles and the 2020 Implementation Guidance, this update reflects real-world experience and responds to persistent challenges such as complexity, limited scale and lack of transparency. It supports development finance providers, policymakers and private investors in designing more effective blended finance solutions that align with partner country priorities and deliver tangible results in low- and middle-income countries.
