Roel Theissen

Dr. R.J. Theissen
Roel Theissen (1968) has worked in the area of banking supervision since 1997; first at the Dutch banking supervisor, then on secondment to CEBS (the Committee of European Banking Supervisors, which has since become the European Banking Authority). In that context he focused on regulation and policy development both domestically (in the Netherlands), cross border (within the EU and in the Basel context) and cross sector (aligning and cooperating with the insurance and securities sectors).
Since 2009 he has been lecturing and writing on prudential supervision in the financial sector, as well as advising on the application of the related laws and policies. Apart from prudential supervision on banks in the EU, this relates to related areas including insurance supervision, the back office of trading venues, conduct of business policy, and the interaction between the EU, its member states and third countries. As a lawyer in Amsterdam, Roel Theissen provided advisory services on financial sector solidity, market access and exit as well as (group) governance of financial institutions until september 2025, when he returned to work for the Dutch supervisor and resolution authority, in its resolution department.
