Mr. Mario Nava:

Yes, capital requirements. That was the first way. Second, in their supervisory discussions with the banks, they had the latitude to step up the requirement only for one particular bank or for a group of banks exposed to that particular risk without necessarily raising the legal requirement - that is, targeting one particular bank or one particular group of banks that were at risk. This is what the supervisors could have done. More detailed guidance on what supervisors could do came later. The realisation of the move from principal base, minimum harmonisation and subsidiarity and the need to give more guidance came with time, so there was nothing that prevented them from doing these things. Also, there was not very detailed guidance as to what they could do.
