The bank also kept minimum reserve requirement ratios unchanged, at 12% for foreign currency liabilities and 8% for local currency deposits.
The key rate has been unchanged since May 2015.
In line with expectations, inflation remained in negative territory in the first two months of the year, reaching -2.68% in February from -0.93% in December 2015, mainly due to the cut in value-added tax from 24% to 20% starting January 2016. The central bank expects inflation will remain in negative territory until June 2016.
The country’s economic growth stood at 3.7% last year, the fastest growth rate in the post-crisis period, mainly driven by consumption, the central bank said.
