The central bank board also decided to maintain rates for deposit and lending facilities unchanged at 1.5% and 3.5%, respectively.
It also left minimum reserve requirements on foreign currency liabilities and for leu deposits unchanged at 8%.
At the rate meeting in June, the central bank kept its benchmark interest rate on hold at 2.5% a year, while tightening control over money market liquidity.
The rate has been kept unchanged since May 2018. Previously, the central bank raised it throughout 2018 after three years of keeping it at a record-low of 1.75%.
