Part of the United Kingdom LEI knowledge hub — back to the United Kingdom pillar.
Regulatory Reporting Using LEI in United Kingdom, the LEI threads through the reporting frameworks supervised by Financial Conduct Authority (FCA) — principally UK MiFIR and UK EMIR — identifying the reporting entity and its 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 LEI may identify the reporting entity, client or counterparty in 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.
