The choice of a horizon over which to bring inflation back to target is equivalent to choosing a point on this volatility trade off. The striking change, however, is the remarkable improvement in the trade-off that followed the introduction of inflation targeting, as can be seen in chart 6. The volatility of both inflation and output growth were much lower than in earlier periods. Part of the improvement may lie in the pattern of shocks over the past decade, although the world economy has hardly contributed to that stability. So the challenge ahead is that if a shock, larger than we have experienced recently but not large relative to historical experience, were to move inflation significantly away from target, then inflation expectations might become dislodged from the target. The behaviour of expectations and so the economy as a whole would change. So far there is little sign that the shocks we have experienced have detached inflation expectations from the target, and that is a source of comfort. But the MPC will continue to pay particular attention to the evidence on inflation expectations. Many of the problems of the past resulted from the failure to take action before expectations had started to drift upwards, and the cost of that inaction proved to be high.
Our forward guidance comprises two elements: it aims to further clarify our views regarding the economic situation and the manner in which we intend to react to it. It is important to note that the United States and the euro area are at completely different stages of the economic cycle. Here in the euro area economy, an imminent change in the direction of monetary policy would certainly come far too early. But how realistic is decoupling from the United States? The markets, at any rate, don’t seem to have all that much faith in that prospect, if you look at the rising money market rates. I think it’s a little early to be judging that. Overall, we believe that we’ve been successful in reducing the volatility of rates. We’ve been moderately successful as regards the actual level of interest rates. Rates have risen on account of positive economic data. It remains to be seen how the situation will develop in the likely presence of further cautiously positive data. And if things do not go according to plan, will the ECB reduce its key interest rates again or conduct new LTROs? We will continue to monitor the situation. We haven’t said any more than that. Sometimes you have to keep calm, rather than coming up with something new every month. Why is the ECB not publishing inflation projections beyond 2014?
