The leu climbed against the US dollar as well, with the indicative reaching 3.804 units, again stronger from a record low of 3.8343 units Tuesday.
The national currency lost 4.2% versus the euro over the past three weeks, amid political tensions after the ruling socialist-liberal coalition won a parliament vote to depose President Traian Basescu. The latter will face a referendum on July 29 on whether he will remain in office.
Since January, the leu weakened by 7.4% against the euro and by almost 15% versus the US dollar.
The leu opened flat on the day at 4.628/4.63 per euro Wednesday and further gained ground, with dealers suspecting an intervention in the market from the central bank.
At around 1:00 pm, the leu traded at 4.618/4.6199 to the euro, after hitting an early high of 4.613 per euro.
In the money market, overnight rates were flat at 4.8%-5.3% a year.
