This paper gives an overview of all development finance sources available to countries of the Organisation of Eastern-Caribbean States (OECS) for enhancing their economic and climate resilience, and progress towards their Sustainable Development Goals (SDGs). After reviewing political and macroeconomic contexts, it examines some of the specific challenges and opportunities they meet in financing their development, including the mobilisation of private finance and domestic resources; public debt sustainability; and the alignment of official development finance (ODF) with their evolving needs. It stresses the risks of inadequately preparing for the end of eligibility to official development assistance (ODA), when countries reach high-income status while remaining highly vulnerable. Finally, it presents recommendations for the OECD Development Assistance Committee (DAC) members to better support and accompany OECS countries as they transition to higher-income status.
