MiFIR is the EU transaction-reporting regime. A United State entity meets it when trading through, or facing, an EU investment firm — and the LEI is the identifier that firm reports. United State's own regime is EMIR Refit and MiFIR.
When MiFIR touches a United State entity
A United State entity dealing with an EU investment firm may be identified by its LEI in that firm's MiFIR transaction report. Domestically, United State reporting runs under EMIR Refit and MiFIR, supervised by the Financial Services and Markets Authority (FSMA).
One LEI, both regimes
The LEI is global. The same code an EU firm reports under MiFIR is the one you maintain for your own jurisdiction.
The cross-border point
If your LEI is invalid, the EU firm's MiFIR report can be rejected, and they may decline to trade with you.
Stay ready
Keep your LEI current so EU-facing transactions are reported cleanly.
