How an LEI rule in one country reaches your business
An LEI (Legal Entity Identifier, a 20-character global code that identifies a legal entity) is no longer just a matter for your own regulator. Your country might not require one. Your counterparty’s country might. And once it does, the requirement becomes yours in practice.
Take a simple case. Your company sits outside the European Union, and you want to trade securities through an EU-regulated investment firm. The legal duty sits with the firm, not with you. Under MiFID II and MiFIR (the EU rules on markets in financial instruments), the firm has to report every reportable trade to its regulator, and that report has to carry your LEI. No LEI, no report. No report, no trade.
So the requirement reaches you through the firm you deal with. That is why the 2026 picture matters to companies everywhere, not only in Europe or the United States. What follows are the main changes this year. Some already took effect, and some are still ahead. Each one states its status, the date, who it touches, and whether the LEI is a hard requirement or is only collected where a code already exists.
When an LEI is a must, and when it is not
The word “LEI requirement” hides two very different things.
A hard requirement means you cannot trade, file, or use a service without a valid LEI. Trading through an EU investment firm works this way.
A soft reference means the LEI is collected only if you already have one. A missing code blocks nothing on its own, but an existing one has to be supplied.
One more point. The LEI is not always the only identifier that counts. In cross-border payments, for instance, other identifiers qualify too, and the LEI is one option among several. We looked at that in our guide to the FATF Travel Rule. In EU derivatives and securities reporting, by contrast, the identifier has to be the LEI. Each entry below says which case applies.
The main changes in 2026
MiCA, European Union: transitional period ended 1 July 2026
Status: in force since 1 July 2026.
MiCA (Markets in Crypto-Assets, the EU regulation for crypto-asset markets) built a single licensing regime for crypto firms. ESMA confirmed on 17 April 2026 that the transitional period would close on 1 July 2026, with no extension. Some member states set a shorter window, so the deadline came earlier in those countries.
Since that date, a CASP (Crypto-Asset Service Provider) cannot serve EU clients without a MiCA licence.
The LEI sits inside this in two places. Authorised CASPs appear in ESMA’s public register under their LEI. And the TFR (Transfer of Funds Regulation) requires a legal-entity originator to be identified by its LEI in transfers between CASPs. The LEI is not a condition of the licence itself, but it is built into the crypto rulebook. We covered the wider regime in our article on MiCA and the LEI.
SEC Form PF, United States: amended-form compliance date 1 October 2026
Status: upcoming, 1 October 2026, and under review.
Form PF is the confidential form that private fund advisers registered with the SEC (Securities and Exchange Commission) file about the funds they run. Amendments adopted in 2024 widen the identifying data they must report, and the compliance date currently sits at 1 October 2026.
The form asks for the LEI of the adviser and of the reporting fund where one exists. So the LEI here is not something you are forced to obtain. It is a field you complete when you already hold a code.
In practice, an adviser running several funds keeps the LEI of each fund, and of the adviser itself, active and current. That way filings go through cleanly, and a lapsed code does not hold one up. Funds, trusts, and special purpose vehicles each count as a separate legal entity, and others may too.
Worth knowing: this date is under active review. The SEC and the CFTC have pushed it back three times, and in April 2026 they proposed further changes to the form. The date could move again. For the wider US position, see our article on the FDTA and the LEI.
India: RBI consolidated direction in force since 27 March 2026
Status: in force since 27 March 2026. UTI from 1 January 2027.
The RBI (Reserve Bank of India) issued a consolidated direction on 27 March 2026 that makes the LEI mandatory for every non-individual market participant. Without a valid LEI, these entities cannot transact in the markets the RBI regulates. That covers over-the-counter deals in government securities, money market instruments, foreign exchange, and derivatives.
The thresholds are concrete. Large borrowers with total exposure of 5 crore rupees (around 500,000 euro) or more need an LEI. Large payments through NEFT and RTGS of 50 crore rupees (around 5 million euro) and above must carry the LEI of both remitter and beneficiary. From 1 January 2027, India also brings in the UTI (Unique Transaction Identifier), a separate code for each over-the-counter derivative trade.
India shows how fast a large market can turn the LEI into a hard rule. We wrote it up in full in our article on the LEI and India.
Mexico: Banco de México Circular 1/2026, phased from 7 July 2026
Status: in force since 7 July 2026, first stage. A further stage follows.
Mexico’s derivatives market now runs on the LEI. Under Banco de México Circular 1/2026, published on 7 January 2026, banks, brokerage firms, investment funds, insurers, and others must hold a valid LEI when they enter into derivatives transactions. The first stage took effect on 7 July 2026.
The rules tighten in steps. Covered institutions have to collect the LEI of counterparties above set thresholds, measured in UDIS (Mexico’s inflation-indexed unit of account). The threshold falls over time, and from 8 July 2027 the LEIs of both parties must appear in confirmations of over-the-counter derivatives. As a rough guide, the thresholds run from about 17 million UDIS (roughly 7.5 million euro) down to about 3 million UDIS (roughly 1.3 million euro).
Already in force, but still catching firms out
Not every important LEI rule is new. Several have applied for years, yet still surprise companies that never checked.
In the United States, the CFTC (Commodity Futures Trading Commission) requires the LEI in swap reporting. If a counterparty is eligible for an LEI, the reporting party has to make reasonable efforts to get one assigned, and a lapsed LEI will not do. This comes from the Dodd-Frank Act, the US financial reform of 2010.
In Europe, the LEI has long been a hard requirement under EMIR (European Market Infrastructure Regulation) and MiFID II. The United Kingdom and Canada run similar regimes, so firms trading into those markets from elsewhere get pulled in too. We went through derivatives reporting in detail in our article on the LEI and EMIR.
On the horizon
Some changes are not in force yet, but they are close enough to watch now.
The EU AMLR (Anti-Money Laundering Regulation) brings a new set of obliged entities into scope from 10 July 2027. Here the LEI is a soft reference, collected where one exists rather than required outright. The largest entities will be supervised directly by AMLA (Anti-Money Laundering Authority), the EU’s new supervisor. We covered the framework in our article on the LEI and anti-money laundering.
The FSB (Financial Stability Board) has a cross-border payments roadmap that points towards wider use of the LEI in payment messages. One caveat matters here. This is a G20 and FSB goal, not a live global mandate. The LEI is not required in cross-border payments today, though the direction of travel is clear.
What to do now
Start with your counterparties. Work out whether any of their jurisdictions reach you. If you trade, report, or deal with participants in the EU, the United States, India, Mexico, and other regulated markets, an LEI may already be a condition of doing business before you enter into a business relationship.
If you do not hold an LEI yet, you can register one in minutes.
Already have a code? Keep it active.
If you already hold one, keep it active. A lapsed LEI can block a trade or delay a filing. Renew your code in good time, and read what happens with an expired LEI.
