Is there a law or regulation that governs the maximum allowable interest amount that can be charged on credit cards or in agreements where credit is extended?
What are those maximums, and do all countries have them? Usury, lending money for any interest at all, used to be anti-biblical: it wasn't a Christian thing to do, and so in Christian countries it was Jews who did it (Jews who were money-lenders). Asking for interest on loans is still anti-Koranic: so Islamic banks don't lend money for interest. Instead of your getting a mortgage from the bank to buy a house, the bank will buy the house, which you then buy from bank on a rent-to-own basis. Further details:
