We do not need the European Banking Authority.
EBA helps regulate and supervise the banking sector.
Result: Bad
The European Banking Authority (EBA) is responsible for testing European banks to increase transparency in the financial system, and identifying weaknesses in capital structures.
The EBA is currently moving away from London, along with many of the Banks.
This is a problem if we want to be seen as a "financial capital".
