The Federal Housing Finance Agency is still weighing final risk-to-capital rules for mortgage insurance firms that conduct business with Fannie Mae and Freddie Mac, with a target release date of mid-December, MI executives told Inside The GSEs. MI sources with knowledge of the situation said the FHFA will likely issue a risk-to-capital minimum of 18:1 compared to the current standard of 25:1. Also, there is talk of a phase-in period and “bi-furcation” for legacy versus new companies.
