So I guess my point is this. It is the collective bond market that determines what I'm going to be paid for owning TIPS, not the Treasury or the Government in general. And it does not particularly matter what CPI is, as long as there is a collective knowledge as to what it is and what is expected of it.
I'm not eager to read the thread, but it seems that owning TIPs wouldn't be too different than owning any other asset. It's another diversifier. Good luck with it though. Maybe I'll buy some someday. I can't help but remember when it recently paid very little for several years, while TREA was taking good care of the job.
