A market-implied rating estimates the market observed default probability of an individual, corporation, or even a country. Indeed, a credit rating is simply a probability of default. [1] The methodology used by Moodys consists in a median piecewise fit of the ratings to the credit defaut swap data observed on the market. [2]

Instead of 5% defaulting, say 10% default, largely due to the fact the LGD has catastrophically risen. To accommodate for that type of situation a much larger expected loss needs to be calculated. This is the subject to considerable research at the national and global levels as it has a large impact on the understanding and mitigation of ...
