Stablecoins are digital assets designed to maintain a consistent value by being pegged to stable assets such as fiat currencies or commodities. By reducing the volatility typically seen in traditional cryptocurrencies, stablecoins provide a reliable means of storing value and facilitating efficient blockchain-based transactions.
They are used widely for payments, cross-border payments and remittances, trading in cryptocurrency exchanges, and for decentralized finance (DeFi) applications. As the digital economy continues to change at a rapid pace the use of stablecoins for many transactions will increase. This guide explores the types, functions, and benefits of these systems.
Here are the key features of stablecoins:
Stablecoins are pegged to fiat currency or commodity assets in order to limit price volatility as seen in other cryptocurrencies.
They have consistent value that makes them both practical and reliable for everyday transactions when compared to the volatility of cryptocurrencies.
Being digital currencies and therefore backed by a blockchain system, stablecoins enable digital payments and transfers worldwide that are fast, secure and low-cost.
It is globally available and can be used to send and receive funds anywhere without the need for traditional banking.
In DeFi, there are many places for borrowing, lending and earning interest for stablecoins.
In the digital economy, stablecoins are very important for many reasons such as they provide a stable medium of exchange, a stable unit of account, and serve as a stable store of value, which volatile cryptocurrencies cannot offer. It allows small payments for everyday use and provides a stable way to transfer value across borders that may allow for the potential elimination of currency risk. Stablecoins represent a concrete practical application for the average consumer in their day-to-day life.
Additionally, it offers crypto traders a means of safety for their assets and is a stable bridge between current centralized finance and cryptocurrency. Stablecoins are vital in developing markets where individual users may either be unbanked or have local currencies that fluctuate widely and negate their buying power, thereby assisting in the development of faster and more democratized financial systems for users independent of legacy banks.
Traditional cryptocurrencies are highly volatile and suited for investment, while stablecoins focus on stability for everyday use.
focus on stability for everyday use.
Stablecoins maintain price stability through two main methods such as asset backing and algorithmic control. Asset-backed stablecoins are supported by reserves like fiat or gold. If prices fall, users buy and redeem them, restoring value, if prices rise, new coins are issued. This relies on transparency and trust in the reserves.
Algorithmic stablecoins use software to control supply. When prices drop, supply shrinks; when prices rise, more coins are minted. While efficient, their stability depends heavily on user trust and consistent market confidence.
Each stablecoin pegging method has its advantages and drawbacks. Fiat-collateralized stablecoins offer the most certainty, as they are backed by real-world assets like the US dollar. However, the assets are frozen and cannot be used elsewhere, and there is always a risk of loss of trust due to potential embezzlement or inadequate transparency in audits. This has led to skepticism around some popular stablecoins, such as Tether (USDT).
Crypto-collateralized stablecoins provide transparency by holding reserves on the blockchain but require overcollateralization due to high volatility. Algorithmic stablecoins avoid holding reserves but struggle with maintaining stability in volatile markets, making their effectiveness uncertain.
Stablecoin business model changes based on the objectives and strategies adopted by the companies. Some companies charge transaction fees and make money when a user trades a stablecoin they created.
Other companies use stablecoins for marketing purposes by providing a stablecoin to increase their brand awareness and promote their overall services. For example, exchanges like Huobi, Gemini, Coinbase, and Circle use stablecoins to attract more users and make it easier to transfer funds within and between their services.
Stablecoins aim for price stability but use different methods, each affecting their reliability and risk as assets.
Fiat-backed stablecoins hold an equal amount of traditional currency in reserve, like US dollars. Users can redeem tokens for real money. This model is simple, transparent, and widely trusted but depends heavily on the issuer’s honesty and regulatory oversight.
These stablecoins are tied to physical assets like gold or oil. They offer stability linked to commodity prices but don’t guarantee a fixed price; instead they move in line with the market value changes of the asset.
Backed by cryptocurrencies, these stablecoins require over-collateralization to counter crypto volatility. Smart contracts manage collateral and liquidate if value drops, offering decentralization but higher complexity and regulatory challenges.
Algorithmic stablecoins maintain value without reserves, using supply adjustments via code. Their stability depends on user trust, but a lack of collateral can lead to failures, rendering them experimental and risky at present.
Stablecoins aspire for a 1:1 peg, but market dynamics constantly threaten this value. One of the primary functions of any stablecoin, like USDC where redemptions take place, is for the holder to be able to exchange their token for "real" currency at face value. This provides a price floor to the asset keeping it close to the dollar. This price floor operates by incentivizing buying when the price decreases and minting new tokens when the price rises.
Arbitrage helps address efficiency by eliminating small price differences rapidly. Traders and bots will routinely buy a token they believe is undervalued while they sell a token they believe is overvalued, all while providing their function of keeping the pool's liquidity relevant for all participants as well as preventing major price volatility.
Yet, trust is inarguably the centerpiece of all financial related matters. Users must trust the issuer is transparent with reserves, safe with their code, and has the ability to redeem their holders. In the absence of these trust signals, there is complacency, which most likely leads to distress of the peg, leading to drift.
Stablecoins are designed to have a steady value, but that stability occurs only when several important elements are aligned. If any of those elements fail (especially from technical, financial, or regulatory contexts), the price of the stablecoin can drift away from its intended peg, and damage integrity and confidence in the marketplace.
The credibility of a stablecoin is reflective of its reserves. Strong reserves (cash, short-dated treasuries) tend to maintain confidence. Weaker reserves (anything crypto or commercial paper, etc.) create confusion and uncertainty. Public audits and comprehensive disclosure are vital; without them, users may not trust the true value of the stablecoin.
Clear and supportive regulatory clarity facilitates trust in stablecoins. Regulatory guidance around reserve requirements, redemptions, and the responsibilities of issuers will set a legal standard for the system. Conversely, unclear legal guidelines, or hostile government responses can tarnish credibility, stunt adoption, and lead to price fluctuations as users worry about future viability.
Stablecoins rely on confidence from users and holders. Those that have a long track record of fulfilling redemptions and surviving market turmoil have a special level of trust. If redeeming experiences become unclear or ambiguous, newer coins or products or products that are not as clear about redemption are more vulnerable to panic selling and confusion. Once confidence is lost, capital will leave quickly, sometimes even faster than a system can adjust.
Widespread usage and liquidity, stablecoins are resilient. More traders, more exchanges and more capital result in fast corrections from price deviations. Thinly traded or niche stablecoins do not have this cushion of liquidity. In a major sell-off in these markets, the stablecoin could break the peg just because of insufficient goods being exchanged to absorb the sell-off.
The system that supports the stablecoin should work flawlessly. Any interruption in redemption access, any bugs in smart contracts or any congestion on a network could result in an interruption in redemption and concessions that could drift price. The technology's robustness of infrastructure via security and scale, must ensure that the mechanics of the coin function under situations of duress and allow for long term price stability.
Companies are finding additional applications for stablecoins outside of the trading realm. For example, payments, payroll, saving, and access are all emerging use cases that are changing how companies transact both domestically and internationally.
Stablecoins can simplify cross-border payments because they allow instantaneous transfer of funds without intermediaries or exchanging multiple currencies. When using stablecoins, it is possible to pay someone in any corner of the world in any situation in a matter of a few minutes.
This is especially useful where financial infrastructure may not be as robust, allowing businesses to pay freelancers or partners in a different country. Stripe supports stablecoin balances in over one hundred countries, which represents a significant reduction in friction and fees.
Businesses operating in high inflation countries utilize stablecoins to hold digital dollars in order to store value or not incur penalties from government currency debasement. Startups in Turkey or retailers in Nigeria can preserve purchasing power without U.S. bank accounts. Bridge by Stripe helps securely manage stablecoin holdings at scale.
Stablecoins streamline payroll for global teams by allowing direct wallet payments. This bypasses delays and bank dependencies, offering faster, more reliable compensation. Workers receive stable-value currency they prefer, and businesses benefit from reduced transfer costs and simplified cross-border transactions.
Some e-commerce platforms accept stablecoins to avoid high FX fees and limited local payment options. Customers can pay in crypto while merchants receive fiat equivalents. APIs and crypto payment cards make this seamless, expanding access for users with limited banking options.
Stablecoins enable digital transactions without the need for traditional bank accounts. In underserved regions, users can store, receive, and spend stablecoins via mobile wallets. Small businesses transact in stable value, and fintechs use stablecoin rails to support USD-equivalent functionality behind the scenes.
Major stablecoins such as USDT, USDC and DAI control the market, offering price stability and liquidity. They are backed by different collateral models and have different risk profiles.
A business wishing to use a stablecoin would try to determine the regulated status, have considered reserve transparency and backing. The stablecoin will have an intended purpose whether payments, savings, operational use.
The World’s largest and oldest stablecoin is Tether, with a market capitalization of $159.1 billion. It is backed mainly through U.S. Treasury bills. Tether serves a multitude of purposes in trading, remittances and DeFi.
Tether has retained its position in the market despite the fact it lost its peg for a brief period in 2022 to U.S. dollar. There are two reasons Tether has maintained dominance in the stablecoin market, liquidity (it is easy to obtain) and consistent profitability.
USDC is owned and managed by Circle and is the largest regulated stablecoin, and is fully backed through fiat. USDC has a market capitalization of $63.13 billion. USDC is a cross-chain stablecoin with availability across multiple blockchains and is used by fintech apps and institutions.
The regulatory trail of USDC is linked to the regulatory focus from Circle. Circle's approach to its offering is a compliance-first strategy, broadly leaving reserve transparency and regulatory certainty in general terms, although the reserve structure of USDC is highly transparent. USDC is a popular option for many businesses and developers.
Dai is a decentralized stablecoin governed by MakerDAO. It maintains its dollar peg through the use of overcollateralized crypto assets and smart contracts. With a $5.37 billion market cap, it offers transparency and independence from traditional banks. However, its partial reliance on USDC has sparked debate over its level of decentralization.
USDe is a synthetic, decentralized stablecoin backed not by reserves but by a hedging strategy involving Ethereum derivatives. With a $5.33 billion market cap, it offers yield to holders and peg stability via arbitrage. However, regulators question its capital adequacy and whether it constitutes an unlicensed security.
Launched in 2025 by Donald Trump’s crypto venture, USD1 is backed 1:1 by the U.S. Treasuries and managed by BitGo. With a $2.2 billion market cap, it operates on Ethereum, TRON, and Binance chains. It’s fee-free for minting and redemption, but remains controversial due to political ties and governance concerns.
The Journal of international economic law article revealed on May 21, 2025, stablecoin regulations are evolving rapidly, with the EU, US, and UK leading the way to deliver stability, transparency, and protect consumers.
The EU's MiCAR framework is leading the fight to regulate stablecoins, classifying them into e-money and asset-referenced tokens. Issuers are required to hold reserves that fully back the issued tokens and they are required to disclose financial records on a monthly basis.
Furthermore, issuers are prohibited from offering interest on stablecoins. National authorities will supervise the issuers, with final oversight from the European Central Bank (ECB), European Banking Authority (EBA) and European Securities and Markets Authority (ESMA).
The MiCAR provisions appear to be stricter for systemic stablecoins on the basis of denomination volume and payment capabilities. However, the failure to clarify what mitigates a 'foreign' stablecoin may hinder a cross border innovation.
The U.S. Lummis-Gillibrand Payment Stablecoin Act aims to regulate USD-linked stablecoins used for payments. It requires 100% reserves and bans algorithmic or interest-bearing stablecoins. Issuers under $10 million market cap are state-regulated, while larger issuers fall under federal oversight from the OCC or Federal Reserve.
Monthly audits and fund segregation are mandatory. The Act allows limited access for compliant foreign stablecoins, addressing risks to financial stability and monetary control.
The UK is establishing a stablecoin framework that focuses on fiat-backed tokens. The FCA leads the regulation and the Bank of England will consider the systemic risks and the Payment Systems Regulator will consider market fairness. Issuers will have to ensure that they maintain 100% liquid reserves, reconcile on a daily basis, and seek FCA approval.
Most likely interest-bearing stablecoins will be banned. The UK intends to issue dual recognition that approves both clean and compliant foreign here in the UK, ensuring international access and strong oversight.
Stablecoins offer utility but also introduce systemic risks, regulatory challenges, and security issues, particularly when integrated with traditional finance and global institutions.
DeFi platforms depend heavily on stablecoins for liquidity. A major stablecoin collapse could trigger a chain reaction and lead to protocol-wide failures.
Banks and institutions adopting stablecoins face exposure to crypto-specific risks. Depegging could cause financial losses and disrupt traditional banking services.
Stablecoins’ borderless nature and pseudonymity make them attractive tools for bypassing sanctions and moving capital out of restricted economies.
Criminals exploit stablecoins to preserve value while obscuring the origins of their funds. Their stability aids illicit finance despite existing compliance mechanisms.
Stablecoins are moving beyond the early-stage hype. They are becoming important tools in the infrastructure of the global financial system. Their potential to enhance and simplify cross-border payments, foster programmable money for global commerce, and allow stable dollars in countries experiencing extreme volatility makes them an important part of the future of money. As more real-world use cases developed, the important role of stablecoins will only grow.
Nevertheless, stablecoins are not a panacea. They need supporting underlying infrastructure i.e., wallet access and conversion, to be fully realized. The next phase of stablecoins will be shaped by how the crypto ecosystem and current financial institutions work together to make stablecoins more usable and accessible across the entire world.
Stablecoins serve as a bridge between traditional finance and digital assets. They provide price stability that traditional cryptocurrencies do not possess. Stablecoins can also facilitate ecosystem use cases such as cross-border payments that are more efficient, DeFi applications, and provide unbanked individuals with access to digital assets.
However, stablecoins still face many challenges and regulatory uncertainties, and it is uncertain what risks systemically to the financial system, users or security threats to stablecoins exist.
The value of stablecoins will continue to be based on trust that users have of acceptable reserves and infrastructure to exchange stablecoins to fiat or other assets. As stablecoins gain adoption and recognition among consumers and institutions, they will continue to play an essential role in the modern digital economy, if they continue to improve their regulatory clarity and technical reliability.
Digital assets are pegged to stable assets like fiat currencies or commodities to minimize price volatility.
Through asset reserves, redemption mechanisms, and algorithmic supply adjustments that maintain the peg.
Fiat-backed, commodity-backed, crypto-collateralized, and algorithmic stablecoins, each with different risk profiles.
