This article is dealing with the monetary policy to adopt by the European Central Bank, especially the one concerning the interest rate which is a very important one, for the upcoming months. The ECB's president, Mr Trichet, is explaining why the organism wants to keep a lower interest rate near 1% in Europe. He is arguing that is not necessary, currently, with the European situation, to increase the interest rate in order to launch again the economic growth and to achieve the main goal of the ECB, which is to maintain the prices stability in Euroland. But with the current situation, the ECB adapts a politic in order to face the situation and the current aim is not to maintain the prices stability because the practise creates some inflation. Moreover, if the ECB keeps a lower rate at 1 percent, that means that the population is able to contract a credit at this cheap rate, and therefore they can hold money to do what they have projected. This low interest is efficient also to face the debt in Europe because the State can refund the deficit a lower rate.
