ORIGINAL: Random While blessedinnyc is correct, I would also add that the spread between the Fed Funds rate and the average rate on a 30 year mortgage is not constant. The Fed could lower rates, but if people are convinced rates will rise in the future, fixed mortgage rates could increase. Realize that the Fed Funds rate is an overnight rate, the very definition of short-term, while a mortgage is long-term debt. quote:

For those who don't know, that means that if the 10-year yield drops 50 basis points, we should also expect a 50 basis-point drop in the 30-year rate. Naturally, that's not always the case in real life (30 year rates tend to be a bit more stable even as 30-year bond prices tend to fluctuate more) Measures of modified duration, risk, and lots of other stuff all assume parallel shifts. I'd imagine that someone smart could make a killing by realizing that everyone in the finance world makes this same assumption and trading against it where appropriate.
