Money burning or burning money is the purposeful act of destroying money. In the prototypical example, banknotes are destroyed by literally setting them on fire. Burning money decreases the wealth of the owner without directly enriching any particular party. However, according to the quantity theory of money, because it reduces the supply of money it increases by the same amount the collective wealth of everyone else who holds money.
Money is usually burned to communicate a message, either for artistic effect, as a form of protest, or as a signal. In some games, a player can sometimes benefit from the ability to burn money (battle of the sexes). Burning money is illegal in some jurisdictions.[1]
