I've been in SACCO for years... I think we get something like 5%. The
Hunderwear one sounds like pyramid scheme. Even if SACCO will offer a loan at 20%, you find that the Sacco borrows from Coop-bank to finance the emergency & Fosa loans so the the net interest income is lower than that of Normal (12%) loan.
Don't expect anything above 5% from a bank as interest on savings.
Why don't you try the 91 day CBK instrument?
