Despite the rising cost of events such as earthquakes in Japan, the country's non-life insurers do not seem to be setting aside enough reserves to cover future disasters. Should a couple of huge catastrophes occur within several years of each other, there are concerns that some might have to dip into, and perhaps exhaust, their capital to cover the shortfall. The Financial Services Agency (FSA), the insurers' regulator, is worried. It wants to tighten rules on how to set aside reserves for natural disasters by April 2004, and is currently studying a report by an industry committee on what to do. About half the industry's premiums come from car insurance, for which policies are renewed annually. Yet in the past year or so, non-life insurers have been selling a growing number of long-term fire-insurance policies (which in Japan cover more general damage to property) that may commit them to huge pay-outs for natural disasters. So far the industry is not resisting the FSA's plans, though that might change if new rules requiring extra provisions pushed some firms into the red.
