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.
As the reporting-party and counterparty identifier across derivative, transaction, and prudential reporting.
Reports are rejected at FCA-registered UK trade repositories and the obligation is unmet until the LEI is reinstated.
Annual renewal and accurate reference data prevent the lapse that causes most reporting failures.
