Part of the United Kingdom LEI knowledge hub — back to the United Kingdom pillar.
LEI for UK regulatory reporting is used across reporting frameworks supervised by the FCA, including UK MiFIR and UK EMIR, to identify reporting entities and counterparties.
Financial Conduct Authority (FCA), through FCA Markets Policy and Wholesale Supervision, oversees the frameworks that reference the LEI. The headline regimes are UK MiFIR and UK EMIR, alongside prudential and statistical returns.
The Legal Entity Identifier may identify reporting entities, clients and counterparties across derivative, transaction, prudential and statistical reporting.
A missing, invalid or incorrectly formatted LEI may cause validation problems or report are rejected at FCA where the identifier is required. The reporting entity may need to correct or renew the LEI before resubmitting the report.
Annual renewal and accurate reference data prevent the lapse that causes most reporting failures.
