Ever wonder what the smartest folks in the room are paying on their mortgages? 

Well, thanks to financial disclosure rules we found out what Fed Reserve chairman Ben Bernanke's paying. The guy who helps set interest rates, of course.

Bernanke refinanced his 30-year mortgage last year at a rate of 4.25 percent.Not bad, Mr. Chairman, but this summer the average rate for a 30-year fixed fell to about 3.49 percent.

Maybe time for another re-fi.
