IMHO, the current interest rates regime should not be interfered with. With inflation at the rate at 16.7% [Feb 2012] and CBR at 18%, I don't see what Kenyans want a sane bank to charge its borrowers.
OK 30% may be on the higher side, but given the risk its is not an "immoral" proposition. My argument has always been... there should be sector specific incentives [probably discounted] that insulates production [or growth] driven borrowings from interest rates fluctuations.
For the rest of Kenyans who borrow from banks to import toys & clothing, banks should charge even more.
BTW, who said banks were making abnormal profits? W.r.t investment, and compared to other industries there is no iota of truth in this. May be they are not as efficient... but that's an argument for another day
