In many financial market contexts, a Legal Entity Identifier (LEI) is required for legal entities participating in regulated transactions or reporting. If your business trades shares, bonds, or derivatives, an LEI may be required depending on the transaction type, venue, and reporting regime involved.
Use this flowchart to determine whether your organization may require an LEI number.
Under MiFID II and UK MiFIR regulations, financial institutions are legally prohibited from executing trades for clients who do not have an active LEI. In some contexts, this is informally described as a ‘No LEI, No Trade’ rule.
If an LEI is required for the transaction and the entity does not have one, a bank or broker may be unable to process the trade.
Determining who needs an LEI number UK often depends on your specific entity type. Whether an entity needs an LEI depends on the type of transaction and the regulatory regime involved.
Limited Companies and PLCs
Any incorporated company in the UK that trades listed securities, bonds, or ETFs on a regulated venue must obtain an LEI. This includes small private limited companies (LTD) as well as larger public limited companies (PLC).
Investment Funds, Pension Schemes, and SSAS
Managed funds, including hedge funds, mutual funds, and Small Self-Administered Schemes (SSAS), require an LEI. While individual SIPPs (Self-Invested Personal Pensions) generally do not need their own LEI, the underlying scheme or provider usually does.
Charities, Trusts, and Foundations
LEI requirements can also apply to some non-profit organizations. If a charity or trust holds investments (such as a portfolio of stocks or bonds), they are classified as a legal entity and must register.
Financial Intermediaries
Banks, credit unions, brokers, and asset managers are mandated to have an LEI not only for their own trading but also to identify themselves in regulatory reports.
Beyond who you are, LEI registration applicability is often triggered by what you do. The table below outlines the specific UK and international regulations that mandate the use of an LEI based on the instruments being traded.
| Regulation | Instruments covered | Entity types | Enforcement date |
|---|---|---|---|
| MiFID II Art 26 | Shares, bonds, ETFs | Investment firms & clients | Jan 2018 |
| EMIR & EMIR-REFIT | OTC & ETD derivatives | Financial & NFC entities | Jun 2014 / Jun 2020 |
| SFTR (EU & UK) | Repos, securities lending | Borrower & lender | Jul 2020 |
| CSDR | Settlement fails reporting | CSD participants | Feb 2022 |
| Dodd-Frank (US) | Swaps | US counterparties | Apr 2013 |
While who needs an LEI number covers most business entities, there are specific exceptions:
