Understanding Stablecoins:
A Comprehensive Overview

By Kavisha Gounden

3 April 2025

In the rapidly evolving landscape of digital finance, stablecoins have emerged as pivotal instruments, bridging the gap between traditional fiat currencies and cryptocurrencies. This article delves into the essence of stablecoins, their various types, functionalities, and the latest developments shaping their trajectory.

What Are Stablecoins?

Stablecoins are a class of cryptocurrencies designed to maintain a stable value by pegging to a reserve asset, typically fiat currencies like the US dollar. This stability aims to combine the benefits of digital currencies—such as fast transactions and security—with the reliability of traditional currencies. 

The Importance of Stablecoins in the Crypto Ecosystem

Stablecoins serve as a critical bridge between the traditional financial system and the cryptocurrency market through the following ways:

  • Medium of Exchange: They facilitate seamless trading between different cryptocurrencies without reverting to fiat currencies.​
  • Store of Value: In volatile markets, stablecoins offer a safe haven for investors seeking to preserve capital.​
  • Remittances and Payments: Their stability and efficiency make them suitable for cross-border transactions and everyday payments.​
  • Liquidity for DeFi: Stablecoins provide a vital role in decentralized finance (DeFi) applications, serving as collateral for lending and borrowing platforms, providing liquidity in decentralized exchanges, and as a means of earning interest through yield farming.

By providing stability and accessibility, stablecoins are helping to drive broader adoption of blockchain technology and cryptocurrencies in both retail and institutional settings.

The Types of Stablecoins

Stablecoins can be categorized based on their underlying stabilisation mechanisms:

1. Fiat-Collateralised Stablecoins

These are backed by reserves of traditional fiat currencies, such as the U.S. dollar, held in custodial accounts. Each stablecoin issued corresponds to an equivalent amount of fiat currency in reserve, ensuring a 1:1 peg. Examples include Tether (USDT) and USD Coin (USDC). 

2. Crypto-Collateralised Stablecoins

Backed by other cryptocurrencies, these stablecoins maintain their peg through over-collateralisation and smart contracts. Due to the volatility of the underlying assets, they are often over-collateralised to absorb price fluctuations. An example is Dai (DAI), which is pegged to the U.S. dollar but backed by Ethereum (ETH) and other cryptocurrencies. 

3. Commodity-Backed Stablecoins

These stablecoins are pegged to tangible assets like precious metals or commodities. For instance, a gold-backed stablecoin represents a specific quantity of gold held in reserve. 

4. Algorithmic Stablecoins

Instead of being backed by assets, algorithmic stablecoins use algorithms and smart contracts to control their supply, aiming to maintain price stability. They automatically adjust the supply of the stablecoin in response to changes in demand. 

How Stablecoins Work

The operational mechanism of a stablecoin depends on its type:

  • Fiat-Collateralised stablecoins: Issuers hold fiat currency in reserves equal to the amount of stablecoins in circulation. Regular audits are conducted to ensure transparency and trust.
  • Crypto-Collateralised stablecoins: Users lock up cryptocurrency assets in smart contracts to mint stablecoins. The system requires over-collateralization to account for potential volatility in the collateral's value.
  • Commodity-Backed stablecoins: Physical assets are stored securely, and digital tokens are issued corresponding to the value of these assets.
  • Algorithmic stablecoins: Smart contracts algorithmically adjust the supply of the stablecoin by minting or burning tokens to maintain the peg.

Recent Developments in the Stablecoin Market

The stablecoin market has witnessed significant growth and transformation, marked by several key events:

Market Expansion

As of December 2024, the total market capitalization of stablecoins surpassed $200 billion, reflecting their increasing adoption and utility in the digital economy. 

Regulatory Landscape

The regulatory environment for stablecoins is evolving:

  • US Legislative Efforts: The US is moving towards introducing stablecoin regulations through the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act (aiming to introduce stringent requirements for stablecoin issues) and the Stablecoin Transparency and Accountability for a Better Ledger Economy (STABLE) Act (that specifies permitted stablecoin issuers may not pay interest or yield to holders.
  • EU Legislative Efforts: The EU established the Markets in Crypto-Assets Regulation (MiCA), which required stablecoin issuers meet additional requirements, such as registering as either a e-money intuition (EMI) or credit institution (CI) and ensuring there is a sufficient liquidity reserve. As a result, in March 2025, Binance announced that it will be delisting nine non-MiCA compliant stablecoins in the European Economic Area (EEA). 
  • UK Legislative Efforts: By 2026, the UK is expected to treat stablecoins as cryptoassets with further information on the full regulatory regime forthcoming. 

Corporate Initiatives

Major financial institutions are also exploring stablecoin ventures:

  • Circle's IPO Filing: Circle Internet Group, the issuer of USDC, filed for an initial public offering on the New York Stock Exchange in April 2025, highlighting the growing mainstream acceptance of stablecoins. 
  • Fidelity's Exploration: Fidelity Investments is testing a dollar-pegged stablecoin, reflecting the increasing interest of traditional financial institutions in the stablecoin market. 

Technological Innovations

The stablecoin landscape is also witnessing technological advancements:

  • Integration with Traditional Finance: Stablecoins are being integrated into traditional financial systems, with banks exploring custody services and payment solutions involving stablecoins.
  • Expansion to Local Currencies: There is a growing trend of stablecoins tied to local currencies, enhancing their utility in various regions.

Transparency and Auditing Efforts

As stablecoin adoption increases, there’s calls for more transparency in the industry:

  • Tether, the issuer of the largest stablecoin by market capitalization, is engaging with a Big Four accounting firm to conduct a full audit of its reserves. This initiative aims to enhance transparency and address longstanding questions about the adequacy of Tether's reserves. 

The Future Outlook of Stablecoins

The trajectory of stablecoins points towards continued growth and integration:

  • Market Growth Projections: Analysts predict that the stablecoin market could double to $400 billion in 2025, driven by legislative developments, fintech adoption, and global payment applications. 
  • Regulatory Developments: The implementation of regulations like the European Union’s Markets in Crypto-Assets (MiCA) and the UK’s upcoming legislation is expected to provide a clear framework for stablecoin issuers, fostering greater institutional participation.
  • Diversification: The emergence of stablecoins pegged to various assets and currencies is likely to enhance their appeal and utility across different markets.

Risks and Considerations

While stablecoins offer numerous advantages, they are not without risks:

  • Regulatory Uncertainty: The global regulatory landscape for stablecoins is still in flux, posing potential compliance challenges.​
  • Collateral Risks: The stability of a stablecoin is contingent on the quality and liquidity of its collateral.​
  • Centralisation Concerns: Fiat-collateralised stablecoins often rely on central entities to manage reserves, which may introduce counterparty risks.​

Stablecoins have solidified their position as integral components of the digital financial ecosystem, offering a blend of stability and efficiency. As the market matures, ongoing regulatory developments, technological innovations, and corporate initiatives will shape the future landscape of stablecoins, potentially leading to broader adoption and integration into the global financial system.
