In finance, fungible refers to the ability of one security to be easily converted into another related security. For instance, stocks are often listed on several stock exchanges, and a fungible stock would allow you to exchange the shares purchased on one exchange for shares on another. Not all securities are fungible in this way, but those that are are somewhat more liquid and protected from volatility on one particular exchange.
