It depend on which newspaper you read....anyway tomorrow is when CBK will update us.That somebody in kenya would be unable to clean their money is the most idiotic thing one can think of. I expect CBK to receive 99.9% of the money back - maybe some old grannies & pastoralist who hide the money under tins & mattresses will be found foul. In fact I haven't seen that 1,000 the last few weeks meaning it was nearly all exchanged.
Of the 217.6 million pieces of the old series Ksh.1000 notes in circulation before June 1, 2019, CBK had made the receipt of 100 million pieces at the end of August leaving out 117.6 million pieces.
