The bank kept the minimum reserve requirements unchanged at 15% for Romanian-leu denominated liabilities and at 20% for foreign currency liabilities.
The rate cut follows several months of reduced inflation, with the annual rate at 3.1% in December, the lowest in over two decades.
The central bank targets an annual inflation of 3% at the end of 2012, plus/minus one percentage point around the band. The bank recently revised down its year-end forecast to 3% from 3.5%, saying it expects a favorable base effect and lower volatile prices.
