The bank cut the benchmark rate in November by 50 basis points, the first cut after holding it for seven straight meetings.

"The Committee ... noted that there was room for further accommodative monetary policy to support economic activity. The MPC therefore decided to lower the CBR to 8.25 percent," the bank said in a statement.

In a Reuters poll of eight economic analysts last week, all expected the rate to be held steady.

Governor Patrick Njoroge told Reuters in November that the scrapping of an interest rate cap, in place since 2016, had removed one of the concerns the central bank had about cutting the lending rate.
