The Christian Church's position on usury began with the First Council of Nicaea in 325, which forbade clergy from engaging in usury.[1] (canon 17) At the time "usury" meant simply interest of any kind, and the canon merely forbade the clergy to lend money on interest. Later ecumenical councils applied this regulation to the laity.[2][1]

Lateran III decreed that persons who accepted interest on loans could receive neither the sacraments nor Christian burial.[3] Pope Clement V made the belief in the right to usury heresy in 1311, and abolished all secular legislation which allowed it.[4] Pope Sixtus V condemned the practice of charging interest as "detestable to God and man, damned by the sacred canons and contrary to Christian charity."[4]

Theological historian John Noonan argues that "the doctrine [of usury] was enunciated by popes, expressed by three ecumenical councils, proclaimed by bishops, and taught unanimously by theologians."[2]

The Hebrew Bible regulates interest taking, but interpretations of the Biblical prohibition vary. One common understanding is that Israelites are forbidden to charge interest upon loans made to other Israelites, but allowed to charge interest on transactions with non-Israelites. However, the Hebrew Bible itself gives numerous examples where this provision was evaded.[7]

Usury (in the original sense of any interest) was denounced by a number of spiritual leaders and philosophers of ancient times, including Plato, Aristotle, Cato, Cicero, Seneca, Plutarch, Aquinas, Muhammad, Moses, Philo and Gautama Buddha.

For example, Cato in his De Re Rustica said:

"And what do you think of usury?" - "What do you think of murder?"

Interest of any kind is forbidden in Islam. As such, specialized codes of banking have developed to cater to investors wishing to obey Qur'anic law.

Il Testo Unico Bancario sancisce che il tasso di interesse massimo oltre al quale un prestito viene definito usurario è stabilito dell'UIC (Ufficio Italiano Cambi).

In questo modo, la Banca Centrale stabilisce i valor minimo e massimo entro i quali variano i tassi di interesse (il tasso di sconto è l'interesse minimo al quale le banche prestano denaro, e l'UIC è costituito presso la Banca Centrale).
