Fungibility is a financial term that refers to the interchangeability of goods or assets of the same type. An item is said to be fungible if it can be mutually substituted for another identical item without any loss of value or integrity. In the financial world, money and securities like stocks and bonds are considered fungible.


The phonetic pronunciation of the word “Fungibility” is: /fʌn·dʒəˈbɪl·ɪ·ti/

Key Takeaways

  1. Fungibility refers to the interchangeability of each unit of a commodity with other units of the same commodity. This concept is essential in markets where it does not matter which particular unit of the commodity is delivered. Commodities like oil, grains, or currencies are considered fungible because each unit is presumed to be the same as another unit.
  2. Non-fungibility is the unique property of a good or asset. Non-fungible assets are unique and cannot be replaced with something else. A good example is collectibles, real estate properties, or digital assets known as non-fungible tokens (NFTs). Each of these assets has a distinct value as they possess unique characteristics that set them apart from a similar class of assets.
  3. Understanding fungibility is crucial in financial systems and trading. The concept of fungibility is deeply embedded in financial systems, influencing the liquidity of markets. The higher the fungibility of an asset, the easier it is to trade with less friction. On the other hand, non-fungible assets are typically harder to trade and may require additional verification to assess their unique value.


Fungibility is a crucial concept in business and finance as it refers to the interchangeability of individual units of a commodity or a financial instrument with other units of the same type. It implies that each unit is capable of mutual substitution, which ensures liquidity in the market. For instance, stocks of the same value from a specific company are fungible as they can be exchanged with one another without losing their inherent value. Without fungibility, trading and market transactions can become complicated and inefficient, as each unit could potentially carry a different value. For businesses, fungibility simplifies operations and lowers transaction costs, contributing to smoother and more effective financial management.


Fungibility serves a vital purpose in finance and business by ensuring fluidity, transactional simplification, and liquidity in markets. Essentially, it refers to the ability to substitute one unit of a good or a service for another identical unit, with no loss in value. Fungibility plays a vital role in capital markets, in the context of equities, bonds, commodities, currencies, and other financial instruments. Goods or assets that exhibit fungibility facilitate trading and exchange, optimize market efficiency, and support price stability by preventing individual units of a product or security from being significantly differentiated.For instance, currency is a classic example of fungibility. No matter which unit you receive—say, a $10 bill—it has the same worth as any other $10 bill. This principle holds true even in complex securities such as bonds or shares; one share of Apple Inc. is just as valuable as another share of Apple Inc. The importance of fungibility extends to cryptocurrencies as well, such as Bitcoin. It is this very fungibility that enables the establishment of standard measurements for trade and commerce, reducing friction and ensuring smooth transactions. Lack of fungibility, on the other hand, can lead to inefficiencies and discrepancies in market operations.


1. Currency or Money: This is the most basic example of fungibility. Within a given denomination of currency, every unit is interchangeable with another. For example, one $20 bill is entirely interchangeable with another $20 bill – they have the same value, and it doesn’t matter which specific $20 bill you have.2. Stocks: In the world of finance and investments, shares of common stock from the same company are considered fungible. One share of company X’s common stock is equivalent to another share of company X’s common stock. They both have the same value and give the holder the same rights and privileges.3. Commodities: Commodities like oil, wheat, and gold are considered fungible because every unit is the same as every other unit. For example, one barrel of crude oil is equivalent to another barrel of crude oil of the same grade. Similarly, one ounce of gold can be interchanged or replaced by another ounce of gold of the same purity.

Frequently Asked Questions(FAQ)

What does fungibility mean in finance?

Fungibility in finance refers to the interchangeability of individual units of a good or asset. If an asset is fungible, each unit of that asset is identical to every other unit, making them interchangeable.

Can you provide an example of fungibility?

Yes, money is a perfect example of a fungible asset. Each individual unit, such as a dollar, euro, yen, etc., is exactly the same as any other unit. Therefore, these units are interchangeable.

Are all assets fungible?

No, not all assets are fungible. Certain assets, like real estate and unique pieces of artwork, are not fungible because each individual unit has its own unique properties and cannot be simply replaced by another.

How does fungibility impact the financial market?

Fungibility is essential in the financial market. With fungible assets, investors can confidently trade units knowing that each unit is identical and has the same value as other units.

Is Bitcoin fungible?

Technically, all bitcoins have the same value, but they are not perfectly fungible. Every Bitcoin transaction is recorded on the blockchain, and if a particular coin is associated with illegal activities, it may be less desirable.

What is the difference between fungibility and liquidity?

Fungibility pertains to the individual units of an asset being interchangeable while liquid assets are those that can be converted into cash quickly and easily without affecting the asset’s value. While all fungible assets are typically liquid, not all liquid assets are fungible.

Can assets become non-fungible?

Yes, certain assets can become non-fungible over time. For instance, if an asset is altered or customized in a certain way to make it distinct, it may lose its fungibility because it is no longer identical to other units of that asset.
