While intensifying climate and disaster risks demand a corresponding surge in investment, the global adaptation financing gap continues to widen. For developing nations, annual investment requirements are projected to reach $310?$365 billion by 2035, while international public finance flows dwindled to just $26 billion in 2023. With needs now outpacing current funding by 12 to 14 times, a massive mobilization of both public and private capital is critical. It is equally -if not more - important to ensure the effective deployment of available financing. The World Bank Group’s recent report, Rethinking Resilience: Adapting to a Changing Climate, promotes a 5 I’s strategy based on income, information, insurance, infrastructure, and interventions. This Live Wire delves into the insurance prong of the 5 I’s strategy in the context of power system resilience. It articulates how disaster risk financing (DRF), including insurance, can preserve liquidity and enable rapid recovery as investment needs grow, while recognizing that the remaining aspects - higher incomes driven by economic growth, progress in risk information, resilient infrastructure, and smart interventions - are inherently interlinked with the design and overall effectiveness of insurance.
