(42)The provision of trade repository services is characterised by economies of scale, which may hamper competition in this particular field. At the same time, the imposition of a comprehensive reporting requirement on market participants may increase the value of the information maintained by trade repositories also for third parties providing ancillary services such as trade confirmation, trade matching, credit event servicing, portfolio reconciliation or portfolio compression. It is appropriate to ensure that a level playing field in the post-trade sector more generally is not compromised by a possible natural monopoly in the provision of trade repository services. Therefore, trade repositories should be required to provide access to the information held in the repository on fair, reasonable and non-discriminatory terms, subject to necessary precautions on data protection.
