Who is? The problem is, we have bonds that the gov't needs to sell each month, and ON TOP OF THAT we have $trillions of dollars of Fed bonds. So every time the yield goes up, the Fed bonds become more worthless, the Fed has less $ to buy bonds, and a vicious, vicious cycle starts.
The problem is, the Fed has said the end is coming, whether it's December, or next year. The cat's out of the bag. That's why the run on bonds.
And Iv'e learned over time/burned, not to catch a falling knife.
That said, I still have 10% of what I had in PTTRX. I wish it was 0%. But someday I'll get back into it. Not anytime soon.
