EONIA

This Euro OverNight Index Average (EONIA) is sponsored by the European Money Markets Institute (EMMI) and calculated by the European Central Bank at 7.00 pm (CET) as a weighted average of all overnight unsecured lending transactions in the interbank market, and carried out before the closing of real-time gross settlement (RTGS) systems at 6.00 pm (CET).

It is reported on an act/360 day count convention and is displayed to three decimal places.

EONIA is widely used as a reference rate for derivatives transactions within the euro-zone.

Distinguish from EURONIA which is sponsored and published by WMBA Ltd in London.
