Reimagining Development Finance in Small Island Developing States

For Small Island Developing States (SIDS), the question of development finance is make-or-break. Home to more than 65 million people, these island nations face a unique challenge. They must tackle inherent socioeconomic vulnerabilities while absorbing the consequences of a climate crisis they did little to create. SIDS contribute less than one per cent of global greenhouse gas emissions, yet for them, rising sea levels and intensifying storms could quickly erase what took years to build. At the same time, each new shock pushes public finances closer to the edge.

SIDS face structural challenges that make sustainable development more challenging and costly: small, dispersed populations that limit domestic markets; geographic remoteness that drives significant dependence on imports and raises the cost of living; and narrow, undiversified economies that offer little cushion against shocks. A single extreme weather event could significantly set progress back and inflict serious damage, amounting to double-digit shares of the Gross Domestic Product (GDP).
