Unique Transaction Identifier (UTI) is one of the key data elements identified globally for reporting of OTC derivative transactions, along with the Legal Entity Identifier (LEI). While the LEI uniquely identifies the counterparties to an OTC derivative transaction, the UTI serves as a single unique reference number for a transaction. In India, LEI has already been implemented. It is now proposed to mandate UTI for all OTC derivative transactions. The feedback and comments from stakeholders are invited.
