MiFIR LEI Requirements in United Kingdom In United Kingdom, UK MiFIR requires investment firms to report transactions with the LEI identifying the buyer and seller. The fields are Article 26 RTS 22 Field 7 and Field 16; reports go to Financial Conduct Authority (FCA).
UK MiFIR transaction reporting requires firms to report completed transactions by the end of the next working day. The LEI identifies the buyer and seller where they are legal entities.
MiFIR Article 26 RTS 22 Field 7 "Buyer identification code" and Field 16 "Seller identification code" use the LEI. A missing or invalid LEI fails validation.
Investment firms supervised by Financial Conduct Authority (FCA) through FCA Markets Policy and Wholesale Supervision, plus approved reporting mechanisms acting for them.
A current LEI clears next-day reporting; a lapsed one fails it. TNV-LEI's reminders keep you compliant.
