When comparing two investments with equal risk, a rational person will choose the investment with a higher rate of return.
This behavior is called Risk Aversion and is a basic tenet of personal investing.
An off-shoot of Risk Aversion is that a rational person will only invest in an instrument of greater risk if the returns are greater, too.
The chart at right illustrates this concept, comparing return rates on two investments:
- U.S. Government bonds
- Mortgage-backed bonds
The difference in investment return rates is sometimes called a "spread" and the historical spread between government debt and mortgage debt is somewhere near 1.5 percent.
However, notice how the spread started to grow starting in July 2007.
July 2007 marked the "official" start of the Credit Crunch and as mortgage delinquencies grew nationwide, so did the market's perceived risk of investing in them.
By the start of this month, the spread had nearly doubled.
But that all changed Sunday. When the government announced its takeover of Fannie Mae and Freddie Mac, it put the same "risk-free guarantee" on mortgage debt that has helped keep U.S. government debt so cheap to finance and the spread immediately shrunk.
This is one reason why mortgage rates fell Monday and why they should continue to stay low over the near-term. With the U.S. government backing the mortgage market, there's no room for the risk premium that helped keep rates high this past year.
It doesn't mean more people will qualify for conforming home loans, but for the ones that do, financing should be cheaper.

Thanks for the explanation in plain english. The question now becomes how this will all affect our tax burden as American taxpayers. Any insight in that arena?
