Legal Entity Identifier requirement mandates large corporate borrowers to obtain and renew LEI to retain credit facilities. The circular mandates that banks require large corporate borrowers with exposures of fifty crore and above to obtain and renew a Legal Entity Identifier (LEI) per a phased schedule; non-compliant borrowers are to be refused renewal or enhancement of credit. Banks must encourage LEI adoption for parent and group entities, obtain LEI from accredited Local Operating Units such as LEIIL in India, ensure renewals per GLEIF guidelines, and record LEI in credit information systems including CRILC.
