In fact, the Treasury plan is simply a backstop to help restore confidence in the GSEs. These backstop measures would support the capital the GSEs are required to hold as protection in dire circumstances (keeping in mind that their regulator has already said they are currently well capitalized). Treasury’s plan is comprised of two parts – a temporary increase in the existing line of credit the GSEs currently have with Treasury in the form of a temporary authorization for Treasury to buy stock and other obligations in Fannie Mae and Freddie Mac and additional oversight authority over the two companies by the Fed. None of these measures is a taxpayer-funded bailout. The GSEs already have a line of credit with Treasury (which they have not used), Treasury simply wants to make sure it is sufficient to serve as a backstop if needed. As to the stock purchase, if Treasury were to buy stock in the either or both companies, it would most likely negatively impact existing shareholders (and thus not be bailing anyone out).
