Stablecoins: Purpose, Types & Influence on the Crypto Market

by Coinmetro


The world of cryptocurrencies is known for its volatility, with prices of digital assets often experiencing wild fluctuations within a short timespan. While this characteristic attracts traders and investors, it can also deter those seeking stability and reliability in their digital holdings and transactions. Stablecoins are a class of cryptocurrencies designed to provide price stability, making them a crucial bridge between the crypto and traditional financial worlds. In this article, we will delve into the purpose, types, and profound influence of stablecoins on the crypto market.

The purpose of stablecoins

Price stability

The primary purpose of stablecoins is right in their name: to maintain stability. Unlike cryptocurrencies like Bitcoin or Ethereum, which can see significant price swings within minutes, stablecoins are engineered to have a stable value. This stability is typically achieved by pegging the value of the stablecoin to an underlying asset or a basket of assets. The most common pegs include fiat currencies like the US Dollar (USD), or a combination of several other crypto assets.

Reducing volatility

Stablecoins serve as a reliable store of value and a medium of exchange within the crypto ecosystem. They allow users to escape the volatility that characterizes many cryptocurrencies. Traders often use stablecoins as a safe haven during periods of market turbulence, converting their assets into stablecoins to protect their value.

Facilitating transactions

Stablecoins are also used as a means of transferring value across blockchain networks quickly and cost-effectively. Traditional bank transfers can be slow and expensive, especially for international transactions. Stablecoins offer a faster and more efficient alternative, making them ideal for cross-border payments, remittances, and everyday transactions.


Stablecoins increase accessibility to the world of cryptocurrencies. They provide a familiar bridge for people who are more accustomed to using traditional fiat currencies. This accessibility can help bring more people into the crypto space, ultimately contributing to the broader adoption of blockchain technology.

Types of stablecoins

Stablecoins come in various types, each with its own method of achieving stability. Here are the main categories of stablecoins:

Fiat-collateralized stablecoins

Fiat-collateralized stablecoins are backed by reserves of fiat currency, such as USD or Euro, held in a bank account. For every stablecoin issued, there is supposed to be an equivalent amount of fiat currency held in reserve. The issuer of the stablecoin is responsible for maintaining this collateral. 


USDT (Tether): Tether (USDT) is a widely known fiat-collateralized stablecoin pegged to the value of the United States Dollar (USD). For every USDT in circulation, an equivalent amount of USD is held in reserve. Tether is one of the earliest and most utilized stablecoins in the cryptocurrency market.

USDC (USD Coin): USD Coin (USDC) is another prominent fiat-collateralized stablecoin, directly pegged to the value of the US Dollar. USDC is issued by regulated financial institutions and operates with a commitment to maintaining a 1:1 backing with USD reserves.


High stability due to the direct backing of fiat currency.

Familiarity and trust associated with fiat currency.


Dependence on centralized institutions to hold and manage the collateral.

The need for regulatory compliance, as fiat assets are involved.

Crypto-collateralized stablecoins

Crypto-collateralized stablecoins are backed by a reserve of other cryptocurrencies, rather than fiat currency. Users lock up a certain amount of cryptocurrency as collateral to mint such stablecoins. These systems often rely on smart contracts to maintain the collateralization ratio. 


DAI: DAI is a crypto-collateralized stablecoin created by MakerDAO. Unlike fiat-collateralized stablecoins, DAI is backed by a basket of cryptocurrencies rather than traditional currency. Users lock up crypto assets, primarily Ether (ETH), as collateral in a decentralized smart contract system. DAI aims to maintain its value close to $1 USD through the governance of the MakerDAO community and the use of decentralized mechanisms.


Decentralized nature, reducing reliance on central authorities.

Increased transparency through blockchain technology.


Vulnerable to price volatility of underlying collateral.

Complex mechanisms to maintain stability.

Algorithmic stablecoins

Algorithmic stablecoins, as the name suggests, rely on algorithms and smart contracts to maintain their stability. They do not have any physical collateral backing, nor are they pegged to a specific asset. Instead, their supply is adjusted algorithmically in response to changes in demand and market conditions. It's important to note that while algorithmic stablecoins have shown promise, there have been instances of failed attempts in the space, such as the well-known case of Terra's UST. These experiences underscore the challenges in achieving stability through algorithmic means and highlight the need for careful design and risk management in this innovative corner of the crypto market. 


No need for physical collateral, reducing dependency on external assets.

Potential for greater decentralization and censorship resistance.


Complexity in algorithm design and governance.

Susceptibility to unanticipated market shocks.

Commodity-backed stablecoins

Commodity-backed stablecoins derive their stability from being pegged to tangible commodities, such as precious metals or other physical assets. The value of these stablecoins is directly linked to the value of the underlying commodities held in reserve. 


PAX Gold (PAXG): Pegged to the value of one fine troy ounce of gold, PAX Gold is backed by physical gold held in vaults. Each PAXG token represents ownership of a portion of that gold.


Inherent Value: Backed by tangible commodities, these stablecoins carry an intrinsic value associated with the underlying assets.

Hedging Against Inflation: As commodities like gold are often seen as hedges against inflation, these stablecoins may offer a degree of protection against currency devaluation.


Dependence on Physical Reserves: The stability of commodity-backed stablecoins relies on the maintenance of reserves in the form of tangible assets, introducing logistical challenges.

Market Fluctuations: The value of the stablecoin can be influenced by the market fluctuations of the underlying commodities, introducing a degree of volatility.

Influence of stablecoins on the crypto market

Stablecoins have had a profound impact on the crypto market since their inception. Here are some key ways in which they have influenced the crypto ecosystem

Trading and liquidity

Stablecoins play a crucial role in cryptocurrency trading. Traders often use stablecoins as a shelter during market volatility. When they anticipate a bear market, they convert their holdings into stablecoins to protect their value. Conversely, they can quickly re-enter the market when they see favorable conditions. This trading strategy is commonly referred to as "going to cash."

Furthermore, stablecoins facilitate trading pairs on crypto exchanges. Some cryptocurrencies are not directly tradable for fiat currencies on exchanges. Stablecoins provide a bridge for traders to enter and exit positions without needing to convert their assets back into traditional fiat currencies. This has increased liquidity in the crypto market and expanded trading opportunities.

Decentralized finance (DeFi)

The rise of decentralized finance (DeFi) has been closely linked to stablecoins. DeFi platforms offer a wide range of financial services, including lending, borrowing, and yield farming, all built on blockchain technology. Stablecoins are the preferred choice for these platforms, as they provide the necessary stability for lending and borrowing without the need for traditional banks.

Users can earn interest on their stablecoin holdings or use them as collateral to borrow other cryptocurrencies. The transparency and programmability of stablecoins make them a perfect fit for the automated and trustless nature of DeFi protocols.

Cross-border transactions

Stablecoins have made significant inroads into cross-border payments and remittances. Traditional cross-border transactions can be slow, costly, and subject to currency exchange rate fluctuations. Stablecoins offer a faster and cheaper alternative, as transactions can be settled within minutes, and fees are often lower than those charged by banks or remittance services.

This use case is particularly valuable for individuals who need to send money across borders to support their families or businesses. Stablecoins enable these individuals to bypass the traditional banking system and benefit from faster and more affordable transactions.

Regulatory scrutiny

The rapid growth of stablecoins has caught the attention of regulators worldwide. Concerns have been raised regarding the potential for stablecoins to undermine the stability of traditional financial systems and the need for regulatory oversight. Regulators are evaluating stablecoin projects to ensure they comply with existing financial regulations, including anti-money laundering (AML) and know your customer (KYC) requirements. In response to these concerns, some stablecoin issuers have begun seeking regulatory approval and oversight to provide greater transparency and assurance to users and regulators alike.

Financial inclusion

Stablecoins have the potential to promote financial inclusion by providing access to financial services for unbanked and underbanked populations. With just a smartphone and an internet connection, individuals can access stablecoins and participate in the global economy. This has the potential to empower people in regions with limited access to traditional banking services.

Potential for Central Bank Digital Currencies (CBDCs)

Stablecoins have also influenced central banks' thinking about the development of central bank digital currencies (CBDCs). Some central banks are exploring the idea of issuing their own digital currencies that would be backed by the central bank and have the stability characteristics of stablecoins. These CBDCs could coexist with private stablecoins and reshape the landscape of digital payments.

Risks and challenges

Depegging risks

Stablecoins, designed for stability, are not without inherent risks that can lead to depegging — deviation from their intended value. Some of the potential risks include:

Collateral Risks: Fiat-collateralized stablecoins, like USDT and USDC, risk depegging if they fail to maintain equivalent reserves, relying on centralized institutions and facing regulatory compliance challenges.

Market Shocks: External factors, such as rapid declines in cryptocurrency prices, can trigger depegging, impacting crypto-collateralized stablecoins like DAI.

Algorithmic Flaws: Algorithmic stablecoins face depegging risks due to programming errors or unforeseen circumstances, emphasizing the complexity in algorithm design and governance.

Regulatory challenges

Stablecoins operate in a dynamic regulatory landscape, presenting challenges that demand quick adaptation from issuers:

Evolving Regulations: Ongoing global regulatory developments create uncertainties for stablecoins, necessitating agile responses to comply with evolving standards.

AML and KYC Compliance: Stricter regulatory scrutiny requires robust Anti-Money Laundering (AML) and Know Your Customer (KYC) practices, impacting user privacy and accessibility, especially in the case of fiat-collateralized stablecoins.

Global Regulatory Variations: Divergent regulatory approaches globally add complexity to stablecoin projects, with different jurisdictions applying varying standards.

Examples of stablecoin failures

Instances of stablecoin failures, such as the TerraUSD (UST) incident, provide insights into challenges faced by these digital assets.

TerraUSD Incident: The significant depegging event raised concerns about the viability of algorithmic stablecoins, demonstrating the susceptibility of these coins to unexpected market shocks.

Lessons Learned: Examining the aftermath of stablecoin failures offers crucial lessons for risk management and governance, emphasizing the importance of careful design and oversight. Transparency in maintaining reserves, especially for fiat-collateralized stablecoins, is crucial to instill trust. Diversifying collateral assets is essential for crypto-collateralized stablecoins to mitigate risks associated with the volatility of specific cryptocurrencies. Algorithmic stablecoins must undergo meticulous design and testing of algorithmic mechanisms, including rigorous simulations and scenario analyses. Furthermore, regulatory compliance is imperative for all stablecoin types, necessitating collaboration with regulatory bodies. Community governance, particularly for decentralized stablecoins, enhances resilience and adaptability. Ultimately, clear communication of risks to users fosters an informed user base.

The future of stablecoins

The trajectory of stablecoins points towards a future shaped by evolving regulatory landscapes and burgeoning opportunities for market growth and innovation.

Regulatory outlook

The regulatory outlook for stablecoins is dynamic, with global authorities actively engaging in shaping frameworks to ensure stability and compliance. As governments and regulatory bodies continue to refine their stance, stablecoin projects are compelled to navigate a complex regulatory environment. Striking a balance between fostering innovation and addressing concerns related to financial stability, consumer protection, and illicit activities remains a focal point for regulatory developments.

Potential market growth and innovation

The potential for market growth and innovation in the stablecoin space is immense. As regulatory clarity increases, stablecoins are poised to become integral components of mainstream financial systems. The prospect of expanding use cases, such as cross-border transactions, and decentralized finance (DeFi) presents exciting avenues for innovation. This evolving landscape holds promise for the continued maturation and diversification of stablecoin offerings, contributing to the broader adoption and integration of digital assets in the global financial ecosystem.

Conclusion & key takeaways on stablecoins

In a world where the crypto market is renowned for its turbulence, stablecoins have emerged as a beacon of stability, offering a reliable bridge between the traditional financial realm and the cryptocurrency ecosystem. These digital assets serve a multifaceted purpose, from maintaining price stability to facilitating seamless transactions and expanding accessibility to blockchain technology.

Stablecoins come in four main categories: fiat-collateralized, crypto-collateralized, algorithmic, and commodity-collateralized. Each type has its own set of advantages and challenges, but all share the common goal of providing stability in a volatile market. Whether it's the direct backing of fiat currency or commodities, the decentralization of crypto collateral, and the algorithmic control of supply, stablecoins offer users a range of options to choose from based on their preferences and risk tolerance.

The impact of stablecoins on the crypto market cannot be overstated. They have ushered in a new era of trading and liquidity, allowing traders to weather storms and seize opportunities with confidence. Stablecoins also form the cornerstone of decentralized finance (DeFi), empowering users to earn interest and access financial services in a trustless and programmable manner.

Furthermore, stablecoins have revolutionized cross-border transactions, offering a faster and more cost-effective alternative to traditional banking channels. They have brought financial services to the unbanked and underbanked, fostering financial inclusion on a global scale.

However, the growing influence of stablecoins has not gone unnoticed by regulators. Concerns about their impact on financial stability and potential for illicit activities have prompted regulatory scrutiny. As a result, some stablecoin projects are proactively seeking regulatory approval to address these concerns and ensure compliance with existing financial regulations.

Looking ahead, the influence of stablecoins continues to evolve. They have inspired central banks to explore the creation of their own central bank digital currencies (CBDCs), potentially reshaping the landscape of digital payments. The profound impact of stablecoins on the crypto market is a testament to their ability to provide stability in an otherwise volatile environment and open the doors of financial innovation to a broader audience.
