Ladies and gentleman, a little Def Leppard to go with your market day.
POMO day again. This time the Treasury was looking to buy Coupons. $33.126 billion were submitted. $8.309 billion were purchased. Net effect on the bond market? Negligible, according to Bloomberg.
I now return you to your regularly scheduled market day.
 I got nothing here. I think they're the interest payments that you have left over when you take regular Treasuries and make STRIPS out of them, but I'm not positive.
