“The strongly increased risks of central banks may act as a constraint on the room for manoeuvre in future monetary policy.” That is the worst case scenario laid out by new research from the Bank of Finland. The thoughtful, comprehensive analysis of eight central banks looks at unconventional tools adopted during the crisis, concluding: “The actions by central banks during the crisis raise a number of questions concerning exit from the measures taken, the impact of the measures, central banks’ risks and independence and their governance structures.”

The turn of the year – and the final post on this blog for 2010 – make a summary of this paper seem appropriate. Which of the unconventional tools – if any – will be discarded in 2011? 

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.
