The leu finished the session at 4.42 per euro, from 4.4395 per euro Tuesday.
The local currency opened at 4.4415 to the euro, but further appreciated, reaching a high of 4.417 per euro in the second half of the session.
Trading volumes were unusually high and the leu’s appreciation was probably prompted by reports that Romanian bonds will be included in a new foreign index, ING Bank Romania’s chief economist Vlad Muscalu said in a note.
The central bank set the leu’s reference at 4.429 to the euro, stronger from 4.4408 per euro Tuesday. Against the US dollar, the leu’s indicative won 0.12% to 3.2891 units.
In the money market, overnight rates were flat at 0.27%-0.77% a year.
