How exactly the Transparency International website that contains public statements critical of E.U. financial regulation backs up your point?

The Transparency International website that you've linked does talk about financial regulation in the EU, but Transparency International's position is that the regulators have failed - that they have not, in fact, clamped down on fraud and corruption, and that close ties between regulators and the banks they're regulating have made them unwilling to act. You're using a web page criticising regulators for failing to take action as proof that they didn't fail to take action.
