They're very obviously based on context and inflation. I'll take the example of the Grameen Bank that I refer to the most.
Commercial loans are 20%, so if you take into account inflation, they're less than an American consumer pays on credit card debt. There are student loans for 5%. There are housing loans for 8%. There are loans to beggars, which is kind of the Grameen equivalent of the Chemen Lavi Miyò, that are interest-free.
So they range from 0% to 20%.
