LSEG FX — institutional liquidity provider
This record reflects the current status of LSEG FX with noted residual risks requiring attention.
Licence, read literally
| Regulator | Licence number | Jurisdiction | Tier | Source |
|---|---|---|---|---|
| FCA | 206017 | UK | tier-1 | open source ↗ |
Tier classification follows the same scale as the retail register: tier-2 means real supervision and client-money segregation, without an investor compensation scheme — never misread it as tier-1 protection.

The claims ledger
Claims specific enough to be falsified — and the ones that remain the venue's own measurement.
Testable claims
- LSEG's own venues page states FXall and Matching together enable FX trades averaging over US$460 billion daily, with 2,400+ institutional clients and 200+ liquidity providers across 500+ currency pairs through FXall (lseg.com/en/fx/venues, checked 10 Sept 2026)
- Through the FXall RFQ platform LSEG offers three regulated liquidity venues: an MTF in Ireland (FX forwards, NDFs, swaps and options), off-venue Singapore trading, and an SEF for NDFs and options; on Matching, FX swaps trade on the MTF and FX spot off the MTF (lseg.com/en/fx/venues)
- In May 2021, following the acquisition of Refinitiv by LSEG, the group initiated migration of its FX trading venues Matching and FXall onto the Millennium Exchange electronic trading software that powers the London Stock Exchange (lseg.com/en/fx/global-forex-trading-ecosystem)
- The LSEG FX SEF factsheet describes FXall as serving more than 2,300 institutions worldwide with liquidity from more than 200 bank and non-bank market makers (lseg.com/content/dam/fx/en_us/documents/sef/lseg-fx-swap-execution-facility.pdf)
Claims we cannot verify from outside
- 'over US$460 billion daily' and 2,400+ client counts are self-published volume figures on LSEG's own marketing pages, not independently audited
- Euromoney 2025 'World's Best FX Venue' write-up cites 400+ liquidity providers and low-latency data centres in London, New Jersey and Tokyo — award-media source, not verified on LSEG's own pages

A firm that publishes its own negative space — who it refuses, where it is not licensed — is materially easier to diligence than one that doesn't. The refusal list is treated here as disclosure, not as a defect.
