Kenya's central bank will align the interbank lending rates with its benchmark lending rate through a new interest rate corridor to lower the cost of credit in the real economy, the International Monetary Fund said.

"The authorities will align the interbank rates with the policy rate and formally announce and implement an interest corridor," the IMF said in a press statement on Monday.

It said the move would strengthen "the monetary policy transmission mechanisms in the context of a floating exchange rate regime."

Closer alignment of the interbank and policy rates will also help the central bank keep inflation within the medium term target of 2.5-7.5 percent, the IMF said.

The central bank was not immediately available for a comment.
