Why Map BIC to LEI?
MiFID II Transaction Reporting
Transaction reports must include LEIs for all counterparties. BIC-to-LEI mapping identifies the legal entity behind a SWIFT code.
EMIR Derivatives Reporting
Trade repositories require LEI codes for derivative reporting. Map the BIC of a clearing member or counterparty to its LEI.
ISO 20022 Migration
The global migration to ISO 20022 messaging enriches payment data with LEIs alongside traditional BIC identifiers.
KYC & Entity Verification
Cross-reference BIC and LEI to strengthen KYC workflows and verify the legal identity behind banking relationships.
