Answer:
Usury.
Step-by-step explanation:
A loan can be defined as an amount of money that is being borrowed from a lender and it is expected to be paid back at an agreed date with interest.
Generally, the financial institution such as a bank lending out the sum of money usually requires that borrower provides a collateral which would be taken over in the event that the borrower defaults (fails) in the repayment of the loan.
However, if a loan is given to a borrower at an interest rate higher than that allowed by an established state law, the lender is said to be guilty of usury, which typically involves the act of charging interest higher than the law permits.
