The IMF and World Bank staff collaborated to develop an experimental macro scenario stress testing approach to examine physical risks for banks by building a dynamic stochastic general equilibrium model link",

      "content": "- The impact of extremely rare typhoons on GDP could already be systemic and could worsen substantially with climate change.\n- Bank capital declines only modestly in the modeled scenarios unless the typhoon event is compounded with other disasters.\n- The modest bank capital decline is attributed in part to the strength of Philippines’ banks and economy before the COVID crisis.\n- Caveat: the model focused only on typhoons’ physical capital destructions and their macroeconomic-level transmissions to banks; further work is required before drawing strong conclusions about the overall relevance of climate risk."
