Fungibility in the context of "Commodity"

A security is a tradable financial asset. The term commonly refers to any form of financial instrument, but its legal definition varies by jurisdiction. In some countries and languages people commonly use the term "security" to refer to any form of financial instrument, even though the underlying legal and regulatory regime may not have such a broad definition. In some jurisdictions the term specifically excludes financial instruments other than equity and fixed income instruments. In some jurisdictions it includes some instruments that are close to equities and fixed income, e.g., equity warrants.

Securities may be represented by a certificate or, more typically, they may be "non-certificated", that is in electronic (dematerialized) or "book entry only" form. Certificates may be bearer, meaning they entitle the holder to rights under the security merely by holding the security, or registered, meaning they entitle the holder to rights only if they appear on a security register maintained by the issuer or an intermediary. They include shares of corporate capital stock or mutual funds, bonds issued by corporations or governmental agencies, stock options or other options, limited partnership units, and various other formal investment instruments that are negotiable and fungible.

A cryptocurrency (colloquially crypto) is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. However, a type of cryptocurrency called a stablecoin may rely upon government action or legislation to require that a stable value be upheld and maintained.

Individual coin ownership records are stored in a digital ledger or blockchain, which is a computerized database that uses a consensus mechanism to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. The two most common consensus mechanisms are proof of work and proof of stake. Despite the name, which has come to describe many of the fungible blockchain tokens that have been created, cryptocurrencies are not considered to be currencies in the traditional sense, and varying legal treatments have been applied to them in various jurisdictions, including classification as commodities, securities, and currencies. Cryptocurrencies are generally viewed as a distinct asset class in practice.

In finance, being short in an asset means investing in such a way that the investor will profit if the market value of the asset falls. This is the opposite of the more common long position, where the investor will profit if the market value of the asset rises. An investor that sells an asset short is, as to that asset, a short seller.

There are a number of ways of achieving a short position. The most fundamental is physical selling short or short-selling, by which the short seller borrows an asset (typically a fungible security such as a share or a bond) and sells it. The short seller must later buy the same amount of the asset to return it to the lender. If the market price of the asset has fallen in the meantime, the short seller will have made a profit equal to the difference in price. Conversely, if the price has risen then the short seller will bear a loss. The short seller usually must pay a borrowing fee to borrow the asset (charged at a particular rate over time, similar to an interest payment) and reimburse the lender for any cash return (such as a dividend or interest) that would have been paid on the asset while borrowed.

A CUSIP (/ˈkjuːsɪp/) is a nine-character numeric or alphanumeric code that uniquely identifies a North American financial security for the purposes of facilitating clearing and settlement of trades. All CUSIP identifiers are fungible, which means that a unique CUSIP identifier for each individual security stays the same, regardless of the exchange where the shares were purchased or venue on which the shares were traded. CUSIP was adopted as an American national standard by the Accredited Standards Committee X9 and is designated ANSI X9.6. CUSIP was re-approved as an ANSI standard in December 2020. The acronym derives from Committee on Uniform Security Identification Procedures.

The CUSIP system is owned by the American Bankers Association (ABA) and is operated by FactSet Research Systems Inc. The operating body, CUSIP Global Services (CGS), also serves as the national numbering agency (NNA) for North America, and the CUSIP serves as the National Securities Identification Number (NSIN) for products issued from both the United States and Canada. In its role as the NNA, CUSIP Global Services (CGS) also assigns all US-based International Securities Identification Numbers (ISINs).
