Debt Sustainability Support Service

SIDS are on the frontline of a global systemic crisis, where climate vulnerability and debt distress reinforce each other. Current international debt-relief mechanisms are inadequate—reactive, narrow, and overly dependent on rigid indicators like income per capita, failing to capture SIDS’ structural fragility.

The DSSS offers a transformative solution through debt restructuring, resilience-investment financing, insurance tools, and expert advisory services. It frees scarce public resources from debt service and redirects them to long-term resilience investments such as renewable energy, nature-based solutions, education, health systems, and adaptive infrastructure.

In doing so, the DSSS strengthens SIDS’ ability to withstand future shocks and builds the foundation for inclusive, green, and sustainable growth.

The ABAS

As recognized in the ABAS, many SIDS face persistent challenges related to debt vulnerability.

This limits the ability of governments to proactively manage debt portfolios, integrate climate and disaster risks into fiscal planning, and engage effectively with creditors and international financial institutions.

The DSSS is a flagship initiative under ABAS and directly fulfills commitments to:
  • Strengthen debt sustainability

  • Increase fiscal space for resilience investments

  • Integrate climate vulnerability into debt treatment

  • Support access to concessional and innovative financing
