FDTA LEI in the US: What the Joint Rule Means

The FDTA LEI joint rule has been in force since October 1, 2026, making ISO 17442, the Legal Entity Identifier (LEI), the shared legal entity identifier standard for nine US financial regulators. It does not, by itself, require a company to obtain an LEI or change an existing report. Whether an LEI affects a particular filing depends on subsequent action by the agency that receives it.

What this means in the United States

For a US company, the first question is which federal agency receives its reports. The Financial Data Transparency Act Joint Data Standards in the Federal Register were issued by the OCC, the Federal Reserve Board, the FDIC, the NCUA, the CFPB, the FHFA, the CFTC, the SEC and the Department of the Treasury. Those agencies selected a joint standard, but each agency’s rulemaking will determine how its data standards apply to particular information collections.

A Delaware LLC that files reports with one of the agencies should identify the agency and check its reporting instructions. A US bank holding company subsidiary that already reports an LEI in some filings should continue to distinguish that existing obligation from any future FDTA-related standard. Neither example establishes a new LEI requirement under the joint rule alone.

The OCC’s codified joint standard names ISO 17442 as the legal entity identifier standard in 12 CFR 15.2 (eCFR). The CFPB’s FDTA joint data standards final rule page is another agency source for the joint rule. For reports submitted to either agency, as for reports submitted to the others, check whether the agency receiving the filing has issued its own FDTA rule. The receiving agency’s requirements, rather than the joint selection alone, will determine when and how an identifier applies.

FDTA LEI: key points for reporting teams

• The joint standard is in force. The rule became effective on October 1, 2026, and selected ISO 17442 for legal entity identification.
• Reporting requirements have not changed through the joint rule alone. Agency-specific action is needed before the new data standards affect reporting.
• Agency rules are the next stage. Each implementing agency must adopt data standards by rule for certain information collections. Those standards must take effect not later than two years after the final joint rule is promulgated.
• The LEI is not the only possible agency-specific choice. An agency may tailor its standards or use another identifier instead of, or alongside, the LEI.

This distinction gives reporting teams a practical way to assess the FDTA final rule LEI standard: record the joint selection, but do not treat it as a new instruction for every filing. Check the rule and instructions applicable to the collection your entity actually submits.

Why the joint rule selected the LEI

The Financial Data Transparency Act of 2022 (FDTA) provides for joint data standards followed by agency-specific rules. Section 124(c)(1)(A) of the Financial Stability Act requires the joint standards to include a common, nonproprietary legal entity identifier available under an open license. The agencies selected ISO 17442 – Financial Services – Legal Entity Identifier (LEI) to meet that requirement.

The agencies describe the LEI as a global, 20-character alphanumeric standard that uniquely and unambiguously identifies a legal entity. They concluded that it meets the requirement for a common, nonproprietary identifier available under an open license. That explains why the LEI appears in the joint standards; it does not determine which entities must supply one in a particular agency filing.

The rule also establishes ISO 4914 UPI for swaps and security-based swaps, ISO 10962 CFI for other financial instruments, ISO 8601 for dates and ISO 4217 for currencies. The agencies did not establish the proposed FIGI standard. These are joint selections, not a substitute for the reporting instructions that apply to an agency’s information collection.

What remains subject to agency-specific rules

Each implementing agency must adopt data standards by rule for certain collections of information and incorporate the joint standards to the extent feasible. An agency may tailor its adopted standards or adopt standards outside the joint rule. In its own rulemaking, it could select an identifier other than the LEI, either instead of or in addition to it.

The FDTA does not require an agency to collect or publish information that it did not collect or publish before the Act. The joint rule likewise does not change reporting requirements without further agency action. For any LEI requirement US regulators apply to a particular report, the relevant agency’s rule and reporting instructions are the sources to check.

GLEIF’s LEI Lightbulb blog no. 22 describes the agency-specific stage as giving each implementing agency up to two years to complete its rulemaking. If the application of a current or future instruction is unclear for your entity, check with the responsible regulator or a qualified adviser.

What to do for your US filings

1. Map the agency and collection. Identify which of the nine agencies receives each relevant filing from your entity. Keep the applicable reporting instructions with that filing.
2. Maintain existing reporting duties. Do not replace a current instruction with an assumption based on the joint rule. If a separate existing requirement calls for an LEI, continue to address that requirement.
3. Check for an agency FDTA rule. When reviewing an agency’s action, establish which collections it covers, when its standards take effect and which identifier it specifies.
4. Review an LEI already in use. If renewal is needed for an existing LEI obligation, you can renew an LEI. If an existing requirement calls for an LEI and your entity does not have one, you can apply for an LEI after confirming which entity the filing identifies.

For background while agency requirements develop, follow US LEI regulation updates. Use the receiving agency’s own rule and instructions, rather than a general update, to assess an actual filing.
