What is a Stablecoin?
What is a stablecoin? A stablecoin is a type of cryptocurrency designed to maintain a stable value by pegging itself to reserve assets like fiat currencies (such as the US dollar), commodities (like gold), or other financial instruments. Unlike Bitcoin or Ethereum, which can experience dramatic price swings, stablecoins aim to provide the benefits of cryptocurrency technology—such as fast transactions, security, and borderless transfers—without the volatility that makes other cryptocurrencies and altcoins unsuitable for everyday use.
The stablecoin market has seen tremendous growth, with a total market capitalization exceeding $235 billion as of 2025, up from $152 billion just a year ago. This rapid expansion underscores the increasing importance of stablecoins in the broader cryptocurrency ecosystem and their potential to bridge the gap between traditional finance and decentralized technologies.
Types of Stablecoins
Stablecoins employ different mechanisms to maintain their stable value. Understanding these types can help you make informed decisions about which stablecoin might best suit your needs.
Fiat-Collateralized Stablecoins
The most common type of stablecoins are those backed by fiat currencies like the US dollar. These stablecoins maintain reserves of the fiat currency at a 1:1 ratio, meaning one stablecoin can be exchanged for one unit of the currency. The reserves are held by independent custodians and are regularly audited to ensure transparency.
Examples: Tether (USDT), USD Coin (USDC), Binance USD (BUSD), Pax Dollar (USDP), and PayPal USD (PYUSD)
Commodity-Backed Stablecoins
These stablecoins are backed by physical assets like gold, silver, or oil. The value of the stablecoin is pegged to the market value of these commodities. Holders can often redeem their stablecoins for the physical commodity, although the process can be more complex than with fiat-backed stablecoins.
Examples: Tether Gold (XAUt), Pax Gold (PAXG)
Crypto-Collateralized Stablecoins
These stablecoins use other cryptocurrencies as collateral. Due to the volatility of cryptocurrencies, these stablecoins are typically over-collateralized, meaning the value of cryptocurrency held in reserves exceeds the value of the stablecoins issued. For instance, $2 worth of Ethereum might be held to back $1 worth of the stablecoin.
Examples: Dai (DAI), which is backed by cryptocurrencies like Ethereum through the MakerDAO protocol
Algorithmic Stablecoins
Algorithmic stablecoins don’t rely on collateral. Instead, they use algorithms to control the supply of the cryptocurrency based on demand. When the price rises above the target value, the algorithm increases the supply to bring the price down. Conversely, when the price falls, the supply is reduced.
Examples: Frax (FRAX), which combines collateralization with algorithmic adjustments
Most Popular Stablecoins
The stablecoin market is dominated by a few major players, each with its own approach to maintaining stability and transparency.
Tether (USDT)
Tether is the largest stablecoin by market capitalization, with a value exceeding $143 billion as of 2025. Launched in 2014, USDT is pegged to the US dollar and available on several major blockchains including Ethereum, Solana, and Tron.
However, Tether has faced scrutiny over its reserve practices. In 2021, Tether Limited was fined $41 million by the US Commodity Futures Trading Commission for making misleading statements about its reserves. Despite these controversies, USDT remains the dominant stablecoin in the market, particularly in Asia and Europe.
USD Coin (USDC)
USDC is the second-largest stablecoin, with a market capitalization of over $58 billion. Issued by Circle, USDC emphasizes transparency and regulatory compliance. Its reserves are held in cash and short-duration US government treasuries, with weekly attestations published to verify these reserves.
When was the first USDC stablecoin issued by Circle? Circle launched USDC in September 2018 in collaboration with Coinbase as part of the Centre Consortium. It was created as a transparent alternative in the stablecoin market at a time when concerns about Tether’s reserves were growing. Since its launch, USDC has grown to become one of the most trusted and widely used stablecoins in the ecosystem.
USDC has gained significant popularity in North America and is widely used in decentralized finance (DeFi) applications due to its perceived stability and transparency.
Binance USD (BUSD)
BUSD is a stablecoin issued by Paxos in partnership with Binance, one of the world’s largest cryptocurrency exchanges. Like USDT and USDC, BUSD is pegged to the US dollar and backed by reserves of US dollars and US Treasury bills.
DAI
Unlike the centralized stablecoins mentioned above, DAI is a decentralized stablecoin created through the MakerDAO protocol. DAI maintains its peg to the US dollar through a system of smart contracts and over-collateralization with other cryptocurrencies, primarily Ethereum. This makes DAI more resistant to regulatory pressures but potentially more complex for new users to understand.
PayPal USD (PYUSD)
Launched by PayPal in collaboration with Paxos, PYUSD represents traditional financial institutions’ entry into the stablecoin market. It’s designed specifically for payments and is backed by reserves managed by Paxos, with regular transparency reports available to the public.
Ripple USD (RLUSD)
RLUSD is the recently launched stablecoin from Ripple, the company behind the XRP Ledger. Announced in 2025, the RLUSD stablecoin has generated significant interest in the cryptocurrency community, with high bids reflecting market enthusiasm prior to its official launch. Designed for cross-border payments and institutional use, RLUSD is pegged to the US dollar and utilizes Ripple’s payment infrastructure to facilitate fast, low-cost international transfers.
It’s important to note that while Ripple has developed the XRP cryptocurrency and now the RLUSD stablecoin, XRP itself is not a stablecoin. XRP is a separate digital asset used primarily for liquidity in cross-border transactions, while RLUSD is specifically designed as a dollar-pegged stablecoin. This distinction is critical for investors and users to understand when navigating Ripple’s ecosystem of products.
Euro Stablecoins
While USD-pegged stablecoins dominate the market, several euro stablecoins have emerged to serve the European market and users worldwide who prefer euro-denominated digital assets. Notable examples include:
- EURT (Tether Euro): A euro-pegged stablecoin issued by Tether
- EURC (Circle’s Euro Coin): A euro stablecoin from the issuer of USDC
- EURS (Stasis Euro): One of the earliest euro stablecoins, backed by euro reserves
- EUROC (Euro Coin): A regulated euro stablecoin gaining adoption in European markets
Euro stablecoins serve similar functions to their USD counterparts but are particularly valuable for European businesses and individuals looking to avoid currency conversion costs when transacting in their local currency.
How Stablecoins Maintain Their Value
The ability of stablecoins to maintain a stable value relies on different mechanisms, depending on the type of stablecoin.
Reserve Assets
Fiat-collateralized stablecoins maintain their value through reserves of the underlying asset. For every stablecoin in circulation, the issuing company should hold an equivalent amount of the backing asset in reserve. These reserves are typically held in bank accounts, Treasury bills, or other low-risk investments.
Pegging Mechanisms
The most common pegging mechanism is the 1:1 ratio with a fiat currency, typically the US dollar. This means one stablecoin is always worth one dollar. Other stablecoins might be pegged to different currencies like the euro (EURC) or a commodity like gold.
Maintaining Stability
To ensure stablecoins maintain their peg, issuers employ various methods:
- Minting and Redemption: Users can mint new stablecoins by depositing the equivalent value in the backing asset, or redeem their stablecoins for the underlying asset.
- Arbitrage: If a stablecoin’s market price deviates from its peg, arbitrageurs can profit by buying the stablecoin when it’s below the peg and redeeming it for the backing asset, or selling it when it’s above the peg. This market mechanism helps maintain the peg.
- Over-collateralization: For crypto-backed stablecoins like DAI, the system requires users to deposit more value in cryptocurrency than the value of stablecoins they receive. This acts as a buffer against price volatility.
- Algorithmic Supply Adjustments: Algorithmic stablecoins use smart contracts to automatically adjust the supply based on demand, theoretically maintaining the peg through market forces rather than collateral.
Transparency and Audits
Many stablecoin issuers publish regular attestations or “proof of reserves” to verify that they hold sufficient backing assets. These reports, often conducted by third-party accounting firms, help build trust in the stablecoin ecosystem.
Benefits of Stablecoins
Stablecoins offer several advantages over both traditional financial systems and volatile cryptocurrencies, making them increasingly popular for various use cases.
Price Stability in Volatile Markets
The primary benefit of stablecoins is their price stability relative to volatile cryptocurrencies. During market downturns, crypto traders can quickly convert their assets to stablecoins to preserve value without exiting the crypto ecosystem entirely.
Cross-Border Transactions and Remittances
Stablecoins enable faster and cheaper international transfers compared to traditional banking systems. This is particularly valuable for remittances, where traditional methods often involve high fees and slow processing times. For example, sending a $200 remittance from Sub-Saharan Africa is about 60% cheaper using stablecoins compared to traditional fiat-based remittance methods.
Financial Inclusion
In regions with limited access to banking services or unstable local currencies, stablecoins provide a way for individuals to participate in the global economy. By offering a stable store of value accessible via smartphone, stablecoins can serve the unbanked and underbanked populations worldwide.
DeFi Applications
Stablecoins are the backbone of many decentralized finance (DeFi) protocols. They facilitate lending, borrowing, and yield farming without the volatility risks associated with other cryptocurrencies. Their stability makes them ideal for liquidity pools on decentralized exchanges.
Bridge Applications
Bridge stablecoins represent an innovative category designed specifically to facilitate transfers between different blockchains. Platforms like Bridge (recently acquired by Stripe for $1.1 billion) specialize in creating interoperable stablecoin infrastructure that allows for seamless movement of stablecoins across various blockchain networks. This cross-chain functionality is critical for the broader crypto ecosystem, enabling users to leverage the strengths of different networks without being confined to a single blockchain’s limitations.
Protection Against Inflation
In countries experiencing high inflation, stablecoins pegged to more stable currencies like the US dollar provide a way for residents to protect their savings from local currency devaluation. This has contributed to high stablecoin adoption in countries like Argentina, Turkey, and Venezuela.
Risks and Challenges
Despite their benefits, stablecoins come with several risks and challenges that users should be aware of.
Regulatory Concerns
Stablecoins continue to attract regulatory scrutiny as they grow in importance. Different jurisdictions are developing regulatory frameworks to address potential risks to financial stability, monetary policy, and consumer protection.
In the United States, both the House and Senate have advanced stablecoin bills that would establish guidelines for stablecoin issuers, including reserve requirements and transparency standards. In Europe, the Markets in Crypto Assets Regulation (MiCA) has effectively banned algorithmic stablecoins and imposed strict reserve requirements on all others.
Reserve Transparency Issues
The transparency of reserves backing stablecoins has been a persistent concern. While some issuers like Circle (USDC) publish regular attestations, others have faced criticism for lack of transparency. Tether, for example, was fined by the CFTC for misleading statements regarding its reserves.
Without adequate transparency, users cannot be certain that a stablecoin is fully backed by the assets it claims, potentially putting their funds at risk.
De-pegging Risks
The history of stablecoins includes several instances where coins have lost their peg to their underlying asset. The most dramatic example was the collapse of TerraUSD (UST) in May 2022, which caused around $45 billion in market value to be wiped out in a week. This event highlighted the vulnerabilities of algorithmic stablecoins in particular.
Even fiat-backed stablecoins can temporarily lose their peg during periods of market stress or if concerns arise about the issuer’s solvency.
Security and Centralization Risks
Most major stablecoins are issued by centralized entities, which introduces counterparty risk and single points of failure. Users must trust that the issuer will manage reserves properly and honor redemptions. Additionally, centralized stablecoins may be subject to freezing or blacklisting of addresses, which undermines the permissionless nature of cryptocurrencies.
Uses of Stablecoins
Stablecoins have a wide range of applications in both retail and institutional contexts, spanning from everyday payments to sophisticated financial operations.
Trading and Investing
Stablecoins serve as a crucial trading pair on cryptocurrency exchanges, allowing traders to move in and out of positions without converting to fiat currencies. This reduces fees and processing times while providing a stable reference point for valuing other cryptocurrencies.
For investors, stablecoins offer a way to “park” funds during market volatility without leaving the crypto ecosystem, enabling them to quickly re-enter positions when conditions improve.
Payments and Commerce
The stability of stablecoins makes them suitable for everyday commerce. Unlike Bitcoin or Ethereum, where price fluctuations could significantly change the value of a transaction between when it’s initiated and when it’s settled, stablecoins maintain consistent purchasing power.
Businesses can accept stablecoin payments with confidence that the value received won’t depreciate, while consumers can spend without worrying that their transaction might cost them more tomorrow due to price appreciation.
Remittances and International Transfers
Traditional cross-border payments through banks or money transfer operators can be expensive and slow, often taking days to settle and charging fees of 5-7% or more. Stablecoins enable near-instant international transfers at a fraction of the cost.
This application is particularly valuable in corridors serving migrant workers sending money home, where traditional remittance costs can significantly eat into the amount received by families.
Store of Value in High-Inflation Regions
In countries experiencing high inflation or currency controls, stablecoins provide a way for residents to preserve their purchasing power. By converting local currency to USD-pegged stablecoins, individuals can protect their savings from devaluation without needing access to physical dollars or foreign bank accounts.
Stablecoins often trade at a premium in these markets, reflecting the high demand for dollar exposure in economically unstable regions.
DeFi Applications
Stablecoins are fundamental to decentralized finance ecosystems, enabling:
- Lending and borrowing: Platforms like Aave and Compound allow users to lend stablecoins and earn interest or borrow against crypto collateral
- Liquidity provision: Stablecoins form half of many popular trading pairs on decentralized exchanges
- Yield farming: Users can earn returns by providing stablecoin liquidity to various protocols
- Synthetic assets: Stablecoins serve as collateral for creating synthetic versions of stocks, commodities, and other assets
Stablecoin Regulations
The regulatory landscape for stablecoins continues to evolve as governments and financial authorities recognize their growing importance in the financial system.
Current Regulatory Landscape
Stablecoin regulation varies significantly by jurisdiction, with some countries embracing them under clear frameworks while others take a more cautious approach. Major regulatory concerns include:
- Financial stability risks
- Consumer and investor protection
- Anti-money laundering and counter-terrorism financing (AML/CFT)
- Monetary policy implications
- Banking system disruption
Regional Regulatory Approaches
United States
In the United States, both the House and Senate have advanced stablecoin bills in 2025. The STABLE Act and GENIUS Act aim to establish frameworks for stablecoin issuers, including reserve requirements, transparency standards, and oversight mechanisms.
The SEC issued a statement in April 2025 indicating that certain “Covered Stablecoins” that maintain adequate reserves and redemption rights might not be considered securities under certain conditions.
European Union
The European Union has implemented the Markets in Crypto Assets Regulation (MiCA), which took effect in 2023. MiCA effectively bans algorithmic stablecoins and requires all others to have assets held in custody by a third party. Reserves must be liquid and maintain a 1:1 ratio of assets to coins.
Singapore
The Monetary Authority of Singapore (MAS) has finalized a regulatory framework for single-currency stablecoins (SCS) pegged to the Singapore Dollar or any G10 currency. The framework focuses on value stability, capital adequacy, redemptions, and disclosures.
Hong Kong
Hong Kong has developed a regulatory framework for stablecoin issuers and launched a sandbox enabling industry stakeholders to develop and test their business models under regulatory supervision.
Future Outlook for Regulation
The trajectory of stablecoin regulation appears to be moving toward:
- Bank-like regulation for stablecoin issuers, potentially including capital requirements, reserve standards, and regular audits
- Greater transparency requirements regarding reserve composition and management
- Consumer protection measures, including redemption rights and disclosure requirements
- Integration with existing financial systems through licensing and oversight frameworks
In the United States, momentum around stablecoin regulation has increased with the current administration expressing support for legislation that would legitimize the asset class while preserving the dominance of the US dollar in global financial systems.
