To analyze what impacts there would be on Mizuho's credit costs in the event that damage to buildings by typhoons and other storms causes stagnation in our clients' businesses and affects their business performance, we employed two approaches: a bottom-up approach reflecting estimates of the number of days of business stagnation for each individual company and a top- down approach reflecting a certain level of stress on portfolios that were likely to see more days of business stagnation than the average. In addition to an impact analysis using the Intergovernmental Panel on Climate Change Fifth Assessment Report's RCP 2.6 scenario assuming a 2 C average temperature rise by 2050, we also conducted an impact analysis using the RCP 8.5 scenario assuming a 4 C average temperature rise by 2050, the worst-case scenario for global warming and physical risk. Under both the 2 C and 4 C scenarios, we estimated that our credit costs would increase by up to $52 billion by 2050.
