In a notice dated Friday, September 12, 2025, DTB announced that it has lowered its base lending rate from 14.21% per annum to 13.77% per annum.
“Diamond Trust Bank Kenya Limited (“DTB”) wishes to notify its esteemed customers and the general public that it has reduced the DTB Base Rate for variable interest rate Kenya Shilling-denominated credit facilities from 14.21% per annum to 13.77% per annum, effective 1 September 2025,” read the notice.
This move is expected to lower borrowing costs for both individual and business clients.
According to the bank, the methodology for calculating interest rates for variable rate Kenya Shilling-denominated credit facilities shall be the sum of:

In compliance, DTB has confirmed plans to transition from its proprietary base rate to the KESONIA/CBR model, as outlined in CBK’s published guidelines.
