Bernanke likes to look at the difference in yields between TIPS (treasury inflation protected securities) and normal treasuries.
I see a major problem with the theory behind it though and I want to discuss that here.
If you KNEW severe deflation was coming then there is no better bet than normal treasuries. You lock in 3% say and then watch the value of your investment rise during the deflation. Things get cheaper and yet your money still grows. It is a perfect situation for you. You will get richer. No doubt about it.
If you KNEW severe inflation was coming there are many better bets than TIPS though. When investors get scared of inflation they often run to gold, silver, food, and energy. That's exactly what we are seeing right now. Further, TIPS cannot protect you against hyperinflation. There's simply too much lag and taxes inherent in them for that.
TIPS are therefore a wimpy bet. They are for people such as myself who KNOW that we don't know (and there doesn't seem to be that many of us). I'm scared of inflation but I'm also scared of yet another bubble (commodities?). I KNOW how sure I would have been in the late 1970s stocking up on gold and silver. I also KNOW, using hindsight, that I would have been dead wrong.
So here's my thinking. If you take the difference in yield between TIPS and their non-inflation protected counterparts you do not necessarily have an accurate gauge of inflation expectations. Those who are sure inflation is coming are mostly off hoarding hard goods (which I'm doing too to some degree since there is very little downside in hoarding something you know you will someday use). They aren't buying TIPS. Heck, they probably aren't just hoarding either. They're leveraging up (not me). This casino mentality we have says that "sure things" need massive leverage in order to maximize returns.
Since hard goods have been skyrocketing in price, I therefore submit that inflation expectations are higher than TIPS would suggest. Heck, for all we know some TIPS holders are actually defecting in this game. Let's say you own TIPS and your inflation expectations rise considerably. Do you buy more TIPS or do you sell what you have and start hoarding hard goods in earnest? If you do the latter you will actually be forcing DOWN the derived TIPS/treasury inflation expectations that Bernanke likes to follow. As you are off hoarding hard goods instead, Bernanke will see inflation expectations even more contained. Now that's a conundrum!
So what does this all mean? Well, if inflation expectations are actually much higher than the TIPS derivation implies, that would also mean that TIPS are a much better bargain than the market is expecting (inflation running hotter than expected would mean TIPS would pay more than expected).
Long-term non-inflation protected treasuries are at the very bottom of my wish list. TIPS and I-Bonds are near the top. They meet my personal risk/reward requirements in this environment. Barring hyperinflation, I won't lose my shirt. Everything is risky though. Everything. I've quoted the following in the past and I'll no doubt quote it again.
In the absence of the gold standard, there is no way to protect savings from confiscation through inflation. There is no safe store of value. If there were, the government would have to make its holding illegal, as was done in the case of gold. If everyone decided, for example, to convert all his bank deposits to silver or copper or any other good, and thereafter declined to accept checks as payment for goods, bank deposits would lose their purchasing power and government-created bank credit would be worthless as a claim on goods. The financial policy of the welfare state requires that there be no way for the owners of wealth to protect themselves. - Alan Greenspan, 1966
Without further adieu here are some VERY stable inflation expectation charts (starting from the point the credit crisis struck last August, when oil was ~$70 a barrel). It sure looks like an illusion to me, but what do I know?
