What does ECI FX sell to market makers?

A 21-currency family you can quote as one book: theoretical mids, a daily publication, and room for your own spread and credit. The construction is licensed; the quotes are what you trade.

Can an exchange list ECI legacy currencies?

Yes. ECI Innovations LLC will stand up calculation, publication and the artefacts a listing committee expects, so a venue can list and match a coherent family.

Is ECI FX a regulated benchmark administrator today?

This public site is informational. Contractual use as a benchmark requires a commercial agreement and a governance mapping. Contact info@ecifx.com.

For market makers, exchanges and LPs

List it, make it, stream it — as one FX family.

ECI Innovations LLC sells the missing infrastructure for Europe’s legacy currencies: live theoretical mids, a daily family publication, and a calculation stack you can contract to. Not a blog post about the franc. A book you can risk.
