Art. 2907. Loan of money or commodities. [...] When commodities are lent, the borrower is bound to return the same quantity and quality regardless of any increase or diminution of value. (Civil Code of the State of Louisiana)

A loan of money is a contract by which a person delivers a sum of money to another person and the other person agrees to return at a future time a sum equivalent to that which the other person borrowed. (Montana Code Annotated 2015)

According to this characterization, I borrowed a certain amount of money from my mortgagee and promised to pay a larger amount of money in the future. This constitutes an interest-bearing loan of money, which the overwhelming majority of jurists (though not all) consider to be a form of the forbidden riba. (Cambridge University Press)
