The LEI is a reference code to uniquely identify a legally distinct entity that engages in a financial transaction. Currently, there are many ways to identify entities, but there is no unified global identification system for legal entities across markets and jurisdictions. The LEI will be a linchpin for financial data—the first global and unique entity identifier enabling risk managers and regulators to identify parties to financial transactions instantly and precisely. Currently, an international collaborative effort between public and private entities is developing the LEI, with the support of the Financial Stability Board (FSB) and endorsement of the G-20.
