The leu closed at 4.466/4.471 per euro, from 4.473/4.475 per euro Thursday.
Elsewhere in the region, the leu’s peers were losing up to 0.7% against the euro after a widely watch report from the European Union showed unemployment in the eurozone rose to a new historic high of 11% in April.
The Romanian currency opened down at 4.479/4.481 per euro, but started to recover shortly after, on suspected intervention from the central bank.
Market participants said the central bank sold EUR400 million Thursday and Friday to keep the leu from weakening too much versus the euro.
The central bank set the leu’s reference at 4.4648 to the euro, slightly stronger on the day. Against the US dollar, the leu’s indicative dropped for the third straight session and hit a new all-time low of 3.6231 units, from 3.5939 units a day earlier.
On the money market, overnight rates were at 4.8%-5.3% a year, little changed on the day.
