First off Bonds are not at 0.1%. And secondly it is not a matter of whether they are happy about the rate or not. Bonds are about safety plain and simple.

I quoted the rate of the one-month t-bill, but you can go all the way up to 30 years and it's only 1.32%. Even that is a rate nobody would be happy with. I know that bonds are all about safety and that is what is driving that yields lower. My point is that this feeling of fear will only subside in the future.
