Negative international sentiment on Greece woes caused the euro to lose ground versus the Swiss Franc Monday, so the central bank computed Monday a reference rate of 3,5598 lei to the franc, compared to the 3.5362 reference used Friday.

The leu opened at 4.220/4.223 against the euro, compared to 4.218/4.2195 at closing in the previous session.

Later, the leu weakened slightly and, at around 10:15 local time, it was trading at 4.217/4.220 against the European coin.

On the money market mid-Monday, overnight rates decreased slightly, to 3.87%-4.37% a year, from 4.07%-4.57% a year.
