The insured losses from a series of explosions at a chemical warehouse in Tianjin on Aug 12 are likely to range from $1 billion to $1.5 billion, Fitch Ratings said in a report on Tuesday.

国际评级机构惠誉18日发布的报告显示，天津化学品仓库8月12日爆炸导致的承保损失金额可能在10亿到15亿之间。

The high insurance penetration rate in this area could make the blasts one of the most costly catastrophe claims for the Chinese insurance sector in the past few years, the report said.

报告指出，较高的保险渗透率可能使天津港爆炸事故成为中国近几年索赔金额最高的灾难之一。

保险渗透率（insurance penetration rate）指某个特定年份内，保险公司承担的保费（premium underwritten）在当年国内生产总值（GDP）中所占的比例，这其中支付的保费可能包括人寿保险（life insurance）、机动车保险（auto insurance）以及健康保险（health insurance）等。
