In general, deteriorated creditworthiness translates into a downgrade action by the rating agencies, such as Standard and Poor's (S&P), Moody's, or Fitch in the United States, and an increase in the risk premium, or credit spread of the borrower. 这里最后一句的意思不就是说credit spread的增加么?那这个是信用风险啊。为什么习题里面有一个credit spread widen following recent bankruptcies要归属为市场风险呢?
