Proprietary trading, also called Nostro trading, refers to trading various financial instruments on one’s own account as opposed to its customers' money, so as to make a profit for itself. Prop trading uses a variety of strategies such as index arbitrage, statistical arbitrage, merger arbitrage, volatility arbitrage, high frequency trading, much like a hedge fund.

The evolution of proprietary trading at banks has come to the point whereby banks employ multiple desks of traders devoted solely to proprietary trading with the hopes of earning added profits above that of market making. These desks are often considered internal hedge funds within the bank, performing in isolation away from client-flow traders. Proprietary desks routinely have the highest value at risk.
