It is not helpful if the public and the markets are confused by what they perceive as possibly contradictory statements about the intents and reasoning in monetary policy, or if the information is too scant to allow the public to make an assessment of the policy. This is an area in which the ECB probably can and should improve.
But there is also another angle to this. Every policy decision results from weighing a number of pros and cons. In the end a judgement is made. It is an unambiguous outcome that can and will be communicated as it comes out from the discussion.
