I learnt some interesting facts about inflation-linked investment products. To begin with Sober Look had an intriguing chart showing an inversion in the TIPS yield curve. Michael Ashton at Epiphany had an interesting explanation for this. Basically, short-dated TIPS begin to trade like gasoline futures . Like zero-coupon inflation swaps, TIPS are indexed to headline inflation, not core inflation. The most volatile component of headline inflation are gas prices, although in general large changes in gasoline prices will mean-revert to core inflation. We've had a large fall in gas prices, so near TIPS have fallen in value. More distant TIPS price in an expectation of gasoline reverting to core, and therefore are less sensitive to the fall in gas prices. Michael explains here why inflation swaps are a better indication of true inflation than TIPS. I learn here that the 5Y 5Y forward inflation curve is the market price for an inflation swap that starts in 5years and ends in 10 years...
