Fungible goods
Fungible is easy to exchange or trade for something of the same type and value [Cambridge Online Dictionary].
Fungible goods refer to securities, or other items, that are equivalent or have many identical parts such that they are interchangeable for practical purposes. Material items, securities, and other financial instruments may be considered fungible goods. If goods are sold by weight or number, they are probably not fungible.
In finance and investing, commodities, common shares, options, and dollar bills are examples of fungible goods. The term "fungible" is not identical to barter or liquidity. A good traded by barter is not necessarily equivalent to the exchanged commodity in units. In other words, it is possible to barter products of different or incomparable value. An item is said to be liquid if you can easily exchange it for money or another good. A fungible good is not necessarily a liquid one.
A commodity must be fungible before it can be traded on a commodities exchange. A specific grade of commodity, such as No. 2 yellow corn, is a fungible good because it does not matter where the corn grew; it is essentially the same product. All corn designated as No. 2 yellow corn is worth the same amount. Stocks are considered to be fungible goods. It makes no difference if Warren Buffett or another famous investor once owned the shares. Cross-listed stocks are also fungible goods. It does not matter if you purchased a share of International Business Machines (IBM: NYSE) in the United States via the New York Stock Exchange (NYSE) or in the United Kingdom through the London Stock Exchange (LSE). Because listed options are considered fungible goods, it is possible to close out positions by taking offsetting positions. For example, if you sell (write) a call option, you can close out the position by buying a call with the same underlying asset, expiration date, and strike price—their components are equivalent. This is known as buying to close [Investopedia].
