An excellent explanation of Fannie & Freddie’s history, and why they’re in trouble.
Fannie Mae’s original role was to buy mortgages from individual banks, package them up into securities, guarantee those securities against loss, and then sell them to other financial institutions. However once Fannie Mae realized that the “golden goose” allowed them to buy those same securities for its own portfolio and lock-in “risk free” profits, Fannie became a major buyer of its own securities. Fannie Mae was thus in the rather bizarre position of guaranteeing an ever increasing portion of its own assets against default.
[By the mid-1990’s] Fannie Mae had become one of the largest buyers of its own securities. Its stock was up over 40X from it’s 1980s nadir and it seemed as though the single biggest problem it had was deciding on how much money it wanted to make. This was a bigger problem than you might imagine because as a quasi-government agency, and a constant political football, Fannie Mae realized it couldn’t be seen to be abusing its market position. So rather than go crazy and buy every mortgage security in sight, Fannie Mae just settled on charting a nice predictable upward growth in earnings fueled largely by buying an ever increasing share of its own securities.
Now a normal private company could not pursue this strategy because as it issued more and more debt to fund the golden goose, the yields on the incremental debt would start to increase to the point where the strategy no longer made sense. But Fannie Mae was different. Because of the implicit government guarantee of its debt, Fannie could issue incremental debt with little or no regard to its existing debt load because everyone assumed the federal government would backstop the debt.
Fannie Mae’s only significant problem thus became that the supply of mortgage securities would prove insufficient to fund its projected earnings growth (which was well above the projected growth in mortgage debt). As a result Fannie began a series of largely successful political campaigns to increase the volume of mortgage securities available to fund their habit.
… Traditionally, Fannie had required the mortgages it purchased to be so-called 80/20 mortgages wherein the borrower puts at least a 20% down payment on the mortgage. This was a requirement because residential mortgages in the US are a “no-recourse” loan in which the borrow can generally “walk away” from the loan with no recourse to the lender other than seizing the house and reporting the default to a credit agency. A 20% down payment was generally thought to be enough to dramatically limit the moral hazard of borrowers “walking away” because housing values would have to decline 20%+ for the borrower to be underwater
… Fannie Mae began a campaign to increase “home ownership” and “affordability”. It created a home ownership “foundation” which opened offices in almost every congressional district and promptly set about mobilizing all the local advocates for “affordable” housing to put pressure on their elected representatives to let Fannie Mae offer “affordable housing programs”. Of course, “affordable housing problems” was just a euphemism for allowing Fannie Mae to lower its underwriting standards so that more mortgages could be created and the golden goose could thus kick out more golden eggs.
