In this interview for the Global Governance Innovation Platform (GGI), Dobrina Poirier, Economic Affairs Officer at UN Trade and Development (UNCTAD), examines how rising borrowing costs and increasingly complex creditor structures are constraining developing countries’ ability to invest in development. She discusses the challenges of sovereign debt restructuring and the need for reforms to the international debt architecture, including the Borrowers’ Platform, a member-led initiative that provides developing countries with a space for peer learning, technical cooperation and greater coordination. She argues that debt should support development rather than undermine it, and that stronger international cooperation is needed to give developing countries a fairer opportunity to invest in their future.
