var is the maximum amount loss due to certain type of risk, within a certain time frame, with a certain probability. the type of risk could be market, credit or operational etc. but often var refers to market var. so car can be intepreted as credit var.

在信用风险的度量中，VAR=CAR+预期损失

谢谢楼上啊

都是風險值 一個算市場風險 一個算信用風險
