The costs of the extensive casualties and property damages, from a series of natural catastrophes in the current fiscal year ending 31 March 2019 (FY2018), will hit the earnings of Japanese P&C insurers, says the international credit agency Moody's. However, the resultant credit impact on the rated P&C insurers will be limited because of their very strong capitalisation and their sound management of catastrophe risk through the use of reinsurance.
