Bank capital requirements are based on a mix of market values and book values. We investigate the effects of a policy change that ties regulatory capital to the market value of the "available-for-sale" investment securities portfolio for some banking organizations. Our analysis is based on...

We summarize and evaluate Fannie Mae and Freddie Mac's credit risk transfer (CRT) programs, which have been used since 2013 to shift a portion of credit risk on more than $1.8 trillion of mortgages to private sector investors. We argue that the CRT programs have been successful in reducing the...
