The rate climbed to 6.5 per cent from 5.4 per cent the month earlier, the Nairobi-based Kenya National Bureau of Statistics said in a statement.
Added to this, the Bureau revealed that prices in the country also rose by 1.3 per cent over the course of the month.
In order to meet its inflation target of five per cent, the Kenyan government may be tempted to leave the key interest rate at 5.75 per cent, the lowest since it was introduced in June 2006, following eight reductions since December 2008.

Figures from the country's NIC Bank show that full-year profits for 2010 were 71 per cent higher than those recorded in 2009.
