Kenya's inflation rose for the fourth straight month in February, to 6.54 percent year-on-year from 5.42 percent in January, mainly due to a rise in the cost of food and transport, the statistics office said on Monday.

The food and non-alcoholic drinks index rose by 1.74 percent as prices of items like maize flour and vegetables went up, while the transport index increased 4.36 percent, Kenya National Bureau of Statistics said in a statement.

Analysts were surprised by a central bank decision to cut interest rates by 25 basis points last month given a perceived threat of higher inflation.
