Usury (from the Latin usus meaning "used") was defined originally as charging a fee for the use of money. This usually meant interest on loans, although charging a fee for changing money (as at a bureau de change ) is included in the original meaning. After moderate-interest loans became an accepted part of the business world in the early modern age, the word has come to refer to the charging of unreasonable or relatively high rates of interest.
Usury laws are state laws that specify the maximum legal interest rate at which loans can be made. This makes most loansharking, another name for usury, illegal. Often, loansharks use illegal "scare" tactics to ensure that the lent money is paid back.
Usury (in the original sense of any interest) is scriptually and doctrinally forbidden in many religions. Judaism forbids a Jew to lend at interest to another Jew. It's forbidden in Islam. The most recent Catholic teaching on usury is by Pope Benedict XIV in his Vix Pervenit from 1745 which strictly forbids the practice, though many Jews, Catholics and Muslims break their own laws in this matter.
While Jewish law forbids the charging of interest to another Jew, Jews are not forbidden to charge interest on transactions to non-Jews. Throughout history, the interest attached to loans by Jews to non-Jews is widely considered to have been a central issue in causing a perception of usury, and contributing to a climate of anti-Semitism: Forceful confiscations of property, and discrimination toward Jews in business practice. Ethnic-based distinctions surrounding the application of interest charges are often perceived as pronounced, discriminatory and unjust, and can inflame existing ethnic divisions.
Usury has been denounced by almost every major spiritual leader and philosopher of the past three thousand years. Plato, Aristotle, Cato, Cicero, Seneca, Plutarch, Aquinas, Jesus, Mohammed and Moses are just a few.
Cato in his De Re Rustica said:
"And what do you think of usury?"
"What do you think of murder?"

Quranic injunctions against Usury
Al-Baqarah 2:275 Those who charge usury are in the same position as those controlled by the devil's influence. This is because they claim that usury is the same as commerce. However, God permits commerce, and prohibits usury. Thus, whoever heeds this commandment from his Lord, and refrains from usury, he may keep his past earnings, and his judgment rests with God. As for those who persist in usury, they incur Hell, wherein they abide forever
Al-Baqarah 2:276-280 God condemns usury, and blesses charities. God dislikes every disbeliever, guilty. O you who believe, you shall observe God and refrain from all kinds of usury, if you are believers. If you do not, then expect a war from God and His messenger. But if you repent, you may keep your capitals, without inflicting injustice, or incurring injustice. If the debtor is unable to pay, wait for a better time. If you give up the loan as a charity, it would be better for you, if you only knew.
Al-'Imran 3:130 O you who believe, you shall not take usury, compounded over and over. Observe God, that you may succeed.
Al-Nisa 4:161 And for practicing usury, which was forbidden, and for consuming the people's money illicitly. We have prepared for the disbelievers among them painful retribution.
Ar-Rum 30:39 The usury that is practiced to increase some people's wealth, does not gain anything at God. But if you give to charity, seeking God's pleasure, these are the ones who receive their reward many fold.
Usury in Scholastic Theology
St. Thomas Aquinas, the leading theologian of the Catholic Church, argued charging of interest is wrong because it applies to "double charging", charging for both the thing and the use of the thing. Aquinas said that a lender charges for the loan by requiring the loan to be paid back, in other words, the payback for the loan is the charge for the loan. Any further charge is a charge for using the loan. Aquinas said this would morally wrong in the same way as if one sold a bottle of wine, charged for the bottle of wine, and then charged for the person using the wine to actually drink it. Some modern theologians believe that this same line of reasoning would invalidate the pricing of computer software, specifically disallowing end user licensing agreements or any restrictions against the end user.
Later, the Protestant John Calvin (father of a Protestant Reformation movement known as Calvinism) defended interest charges, helping to set the stage for the development of capitalism in northern Europe. Such a connection was advanced in influential works by Richard H. Tawney and by Max Weber.
