Stablecoins

tl;dr: Stablecoins are a type of cryptocurrency designed to maintain a stable value relative to another asset, such as the US dollar or gold, providing the benefits of cryptocurrencies while minimizing volatility. They can be backed by fiat currencies, precious metals, or even other cryptocurrencies and are commonly used for payments, transfers, or as a store of value. There are three primary types of stablecoins: fiat-collateralized, cryptocurrency-collateralized, and commodity-collateralized. However, individuals should exercise caution when using or holding stablecoins, as their effectiveness in maintaining stability can vary, and there is a risk of the issuer not holding sufficient collateral to support the stablecoin's value or the algorithmic mechanics being flawed, as demonstrated by the collapse of TerraUSD and Luna in May 2022.


What Are Stablecoins?

Stablecoins are a type of cryptocurrency designed to maintain a stable value relative to another asset, such as the US dollar or gold. The primary goal of stablecoins is to offer the benefits of cryptocurrencies, including fast and inexpensive transactions, while mitigating the volatility often associated with other cryptocurrencies like Bitcoin.

Stablecoins can be backed by various types of assets, including fiat currencies, precious metals, or even other cryptocurrencies. Some stablecoins are purportedly fully backed, meaning that for each unit of the stablecoin in circulation, there is an equivalent unit of the underlying asset held in reserve. Conversely, other stablecoins may be partially backed, indicating that they possess some, but not all, of the underlying asset in reserve.

Typically, stablecoins are used as a means of payment or as a store of value. They can facilitate purchases, transfer funds between individuals or businesses, or hedge against the volatility of other cryptocurrencies. Additionally, some stablecoins offer extra features, such as privacy or programmability, that make them suitable for specific use cases.

Different Types of Stablecoins

There are various types of stablecoins, which can be categorized based on the asset to which they are pegged. Here are the three primary types of stablecoins:

  • Fiat-collateralized stablecoins: These stablecoins are backed by fiat currencies, such as the US dollar or the Euro, held in reserve by the issuer. Examples of fiat-collateralized stablecoins include Tether (USDT), USD Coin (USDC), and TrueUSD (TUSD).
  • Cryptocurrency-collateralized stablecoins: These stablecoins are backed by other cryptocurrencies held in reserve by the issuer. Examples of cryptocurrency-collateralized stablecoins include Dai (DAI), which is primarily backed by Ether (ETH) and USDC. Most cryptocurrency-collateralized stablecoins are also algorithmic stablecoins, meaning they employ an algorithmic mechanism to maintain stability.
  • Commodity-collateralized stablecoins: These stablecoins are backed by physical commodities, such as gold, held in reserve by the issuer. Examples of commodity-collateralized stablecoins include Paxos Gold (PAXG) and Tether Gold (XAUT).

Each type of stablecoin has its advantages and disadvantages, and their effectiveness in maintaining stability may vary depending on market conditions and the mechanism utilized.

Individuals should exercise caution when using or holding stablecoins, as the issuer may not maintain sufficient collateral to support the stablecoin's value, or the algorithmic mechanics of a stablecoin could be fundamentally flawed, as demonstrated by the collapse of TerraUSD and Luna. In May 2022, TerraUSD dropped to US$0.10, losing its peg to the US dollar, and consequently, Luna's value plummeted nearly to zero. This event eradicated $45 billion of market capitalization in just one week. As a result, individuals should thoroughly research and comprehend the underlying mechanics and risks of stablecoins before using or holding them.
