Recital 58

It is necessary to reinforce provisions on exchange of information between competent authorities, ESMA and other relevant authorities and to strengthen the duties of assistance and cooperation between them. Due to increasing cross-border activity, those authorities should provide each other with the relevant information for the exercise of their functions so as to ensure the effective enforcement of this Regulation, including in situations where infringements or suspected infringements may be of concern to authorities in two or more Member States. For the exchange of information, strict professional secrecy is needed. It is essential, due to the wide impact of OTC derivative contracts, that other relevant authorities, such as tax authorities and energy regulators, have access to information necessary to the exercise of their functions.
