About these figures
Each figure is the weighted average rate of the bids the Central Bank of Kenya accepted at that auction, as published in its results. The change compares an auction with the previous auction of the same tenor. Interest on Treasury bills is subject to 15% withholding tax, so what reaches you is lower than these rates.
