A trade repository (TR) is defined by the European Securities and Markets Authority (ESMA) as “an entity that centrally collects and maintains records of securities financing transactions”. For the TR, this means validating, storing and matching transaction reports, making those reports available to authorised regulators and aggregating and anonymising the reported data as public information. Trade Repositories play an important role in enhancing the transparency of derivative markets and securities financing markets, and thus of the financial system. For this reason, they are heavily regulated by the government agencies in charge of financial markets supervision.
