In this episode, I speak with Matthieu Pegon, Director of Blended Finance at IDB Invest, who shares insights on how blended finance can unlock private capital for sustainable development in emerging markets. Matthieu reflects on the role of development finance institutions (DFIs), the critical use of concessional capital, and the importance of risk perception and catalytic capital in mobilizing private investment. We also explore key learnings from IDB Invest's experience in promoting gender equality and discuss the ongoing challenges of scaling concessional finance to achieve development outcomes. This episode is essential for anyone looking to understand how blended finance can drive impactful investment in underserved markets.
