 So your friend picks up a 5.5% bond, sees you a few weeks later and says, hey, look at my bond. I got an even better one than you. And now all of a sudden your bond doesn't look so good. So what do you do? If you want to get a new 5.5% bond, you've got to sell your bond on the open market. But who's going to want to buy your bond if they can get a new one for 5.5%? So you've got to take a haircut on yours. Someone would buy your 5% bond if they paid less for it.
