ABSTRACT:The IMF provides macro-stabilizing liquidity when others cannot. The IMF has developed a set ofinstruments designed to provide rapid financial assistance to countries facing urgent balance of payments needswithout requiring a full-fledged economic program, triggered by exogenous natural disasters shocks. We evaluate theimpact of IMF emergency financing after natural disaster using a synthetic control method. The results show that IMFpost-disaster financing supports a fasterGDPrecovery, withan implied average IMF post-disaster multiplierlargerthan 1. The findings suggest strong liquidity and catalytic effects, enabling countercyclical fiscal responses. However,the resulting increase in public debt underscores the need for credible medium-term fiscal plans and post-disasterconsolidation to maintain debt sustainability.

When a large natural disaster shock occurs, timely and effective external financingis critical to supportthe recovery, stabilize macroeconomic conditions, and avoid disorderly adjustments andlong-lasting scarring. While long-term adaptation and resilience-building are essential, even well-preparedcountries face temporary liquidity shortages when natural disaster shocks hit. The IMF’s Emergency NaturalDisaster Assistance (ENDA), Rapid Cre
