It's quite possible that we will have to create the new institutions for the euro zone first.

My job is not to predict everything that might happen in the future, but to address what we can do today.

At the moment we are facing a whole collection of difficult to forecast developments from the situation in China and the oil-price crash to the worrying news from some banks in Europe and the US. All of that is linked: Worldwide company debt is high and there is a lot of money in circulation. That is why necessary structural reforms are not being made.
