Did you feel at any point that, as regards Greece, the political leaders handed you a hot potato? No. However, what the whole experience shows is that our Union is still imperfect and needs to become a “more perfect union”, to borrow a phrase from the constitutional tradition in the United States.
A union where the central bank is called upon by certain politicians to decide on the membership of certain states cannot be right. The central bank should just do the work of a central bank, i.e. maintain price stability over the medium term, and should not be called upon to take such decisions. That is why we have to move towards greater political integration.
