Understanding Aggregate Default Rates of High Yield Bonds

Understanding Aggregate Default Rates of High Yield BondsThe fraction of all high yield issuers defaulting in a given year has fluctuated greatly in the recent past. Since 1981, the aggregate default rate averaged just under 4½ percent, but the level of aggregate defaults varied considerably from year to year. Defaults ranged from as high as 11 percent in 1991 to less than 2 percent in 1981
