The Blended Finance Principles and the Blended Finance Guidance are effective policy tools for donor governments, development co-operation agencies, philanthropies and other stakeholders to design and implement effective and transparent blended finance programmes.

The OECD Development Assistance Committee (DAC) endorsed the Blended Finance Principles for Unlocking Commercial Finance for the Sustainable Development Goals  (also available in German) at its High Level Meeting in 2017. The Principles have since shaped policy discussions in several fora, such as the UN, EU and World Economic Forum, G20 and G7.
