Pressure for such publication is going to mount inexorably until the ECB complies with international best practice. This is the practice of the Fed in the United States, of the bank of England, of the Swedish RiksBank and even now also the Bank of Japan. The arguments against publication of minutes and of regular forecasts amount to little more than special pleading. Nobody likes to have their work examined. As George Bernard Shaw remarked all professions are conspiracies against the laity.
Central banking is no exception.
The most basic argument in favour of transparency is quality control. The best way of ensuring an institution continues to be efficient is to open its procedures to scrutiny. Indeed, it is hard to see how the European Parliament could discharge its mandate of scrutinising the ECB if the bank's Council does not open up. It is not enough to judge a central bank just by results in terms of price stability. It may achieve its objective by good fortune having made misjudgements.
