Each central bank must have all the instruments at its disposal and at its free disposal in order to execute all operations related to a central bank's core activity, in particular in the area of monetary policy, foreign exchange, as well as payment systems. On the other hand, I think the financial independence is also increasingly attracting attention.
It means that a central bank ought to rely on a robust balance sheet in order to underline its independence. But financial independence also applies to the personal independence of the people running the central bank. I think that as a Luxemburger I should not give anyone a lesson in this respect.
