Last week brought a first in the area of the monetary policies promoted by the main European central banks, the European Central Bank and the Bank of England.

Financial Times reports that the Bank of England, under the leadership of new governor Mark Carney, has set off into a series of "preannouncements" much earlier than the market expectations.

Words are all that is left. The statements of Ben Bernanke, who is still the chairman of the Federal Reserve, about a possible slowdown of the quantitative easing program, have forced the European Central Banks to "swear" that they would not abandon printing money.

Jeremy Warner writes in The Telegraph that "the ECB settled for saying little and riding the wave as long as the Fed used quantitative easing", but it has now been forced to express its point of view. The Financial Times writes that the preannouncement of the Bank of England came one month early, with its goal being "to show the markets that they were wrong when they assumed the gradual drop of the ultra-loose monetary policy by mid 2015".
