Fungibility Fungibility In economics, fungibility is the property of a good or a commodity whose individual units are essentially interchangeable. For example, since one kilogram of pure gold is equivalent to any other kilogram of pure gold, whether in the form of coins, ingots, or in other states, gold is fungible. Other fungible commodities include sweet crude oil, company shares, bonds, other precious metals, and currencies. Fungibility refers only to the equivalence of each unit of a commodity with other units of the same commodity and not to the exchange of one commodity for another, which is barter.

Commodity broker commodity contracts. They advise commodity pools and offer managed futures accounts. Like an IB, a CTA does not hold customer funds to margin; they are held at a FCM. CTAs exercise discretion over their clients' accounts, meaning that they have power of attorney to trade the clients account on his behalf according to the client's trading objectives. A CTA is generally the commodity equivalent to a financial advisor or mutual fund manager. Commodity Pool Operator (CPO): a firm or individual that operates commodity pools advised by a CTA. A commodity pool is essentially the commodity equivalent to a mutual fund.
