donheff said:It looks like we need Saluki to run numbers showing the variations of expected coupon rates vs inflation rates over 10%. Since TIPS are new (aren't they?) there won't be historic coupon rates but they could probably be projected backwards by matching the ones we have against a bond index??
TIPS have been around since 1997, IIRC. The first auctions were for 10 and 30-year TIPS. The first 5-year TIPS auction was October 2004 (see my post above). Prior to TIPS there really was no way to know what real interest rate expectations or inflation expectatations really were. Now you can extract a number for market expectations of inflation by comparing the yield on a TIPS with the yield on a regular Treasury note or bond of the same maturity; and real rate expectations from the YTM of TIPS. Currently the YTM's on 5-year TIPS and 5-year Treasury notes are 2.65% and 4.76%, respectively, so from this one can infer that the market is expecting inflation of about 2.1% per year for the next 5 years. See
http://www.bloomberg.com/markets/rates/index.html
for these data and also data for other maturities. From the past TIPS data we have, coupons on 5-year TIPs have ranged from 0.875% to 2.375%. If you look at coupons on longer dated TIPS from previous auctions you will see that they have ranged from 1.625% to 4.25%. For coupons on past auctions see:

From this you can see that the market's expectation for real interest rates jumps all over the lot. This is why, as Brewer pointed out in an earlier post, TIPS can exhibit greater price volatility than conventional bonds. The duration with respect to real interest rates of a 30-year TIPS with a coupon of 2.5% is about 20.
