It is a comparison of the 30Y, 10Y, 5Y, 3Y, and the 1 month yields.
Seems the majority of the money has been scrambling to short-term safety sending the 1 month T-bill down to a record low of .01%. It can not be a good sign when large investors get to the point of just trying to protect their money with no reward. Yields on the longer term T-Bills are growing at a substantially faster rate the further out in time they are, as the number of bidders have declined.
I get a really bad feeling the little guy will be left holding the bag, As the large investors have been fleeing to the safety of short term T-bills, the obvious question becomes where were they fleeing from?
