The Vickers Report on banking reform made a number of recommendations for new regulations, many of which cannot be legislated for by Parliament. One recommendation was that banks maintain a 10% capital buffer. At the moment this is actually illegal under European law and Parliament cannot pass a Bill to implement it because the matter is covered by EU regulations.
It strikes me as a bit of a stupid report if it is making recommendations which are impossible to be introduced.
In what way does the EU prevent this 10% buffer?
