inflation-linked bonds

Using inflation-linked bonds to forecast inflation? Beware – new research suggests they are only decent predictors in the short-term. Over long horizons, the relationship is actually negative:

We showed that the break-even inflation is informative about future inflation over horizons of 3, 6, 24 and 30 months. For the 3- and 6-month horizons, besides being informative, break-even inflation is an unbiased estimator as well. However, over the horizons of 24 and 30 months, the relationship between the break-even and future inflations is negative. On the other hand, for the horizons of 12 and 18 months, breakeven inflation has almost no power to explain future inflation. Read more
