In the blockchain industry, fiat currency was among the first mainstream real-world assets (RWAs) to be tokenized. Stablecoins serve as the cornerstone of value exchange in decentralized finance (DeFi). As the name suggests, a stablecoin is a type of cryptocurrency designed to maintain a stable value by being pegged to a fiat currency issued by a central bank. Dollar-backed stablecoins are among the most held and traded assets in the DeFi ecosystem.
How Stablecoins and Fiat Currency Serve Different Purposes
Throughout much of DeFi's history, stablecoins have primarily been used to transfer value from one address to another. They enable instant on-chain settlements, international transfers, and high-frequency trading. While similar activities can be performed using fiat currency, the key difference lies in how these assets are stored.
Individuals often keep significant portions of their savings in low-risk investments such as fixed deposits and government bonds. These investments are unlikely to depreciate, generate interest, and ensure that funds remain accessible.
In contrast, stablecoins are typically held in exchanges or cold wallets, where they do not generate interest and gradually lose value due to inflation. Traditional stablecoins lack an inherent yield component. Yield-bearing stablecoins, however, earn passive interest, making them functionally closer to fiat currency in terms of value preservation.
This article explores yield-bearing stablecoins, explains how they function, and discusses the mechanisms through which they generate returns. As DeFi continues to evolve, understanding these emerging assets is crucial for maximizing investment potential.
What Are Yield-Bearing Stablecoins?
Yield-bearing stablecoins function similarly to fixed deposits and government bonds in traditional finance. These low-risk, low-volatility assets include a yield component, allowing holders to earn returns simply by keeping the tokens in their wallets.
Consider how traditional banking works: when you deposit money into a bank, the bank maintains a digital ledger tracking your transactions. While you can spend, transfer, or withdraw funds freely, the bank lends the actual money to borrowers. The interest generated from these loans is partially passed back to you. Your bank account effectively acts as a tokenized representation of your deposit, usable even while the underlying assets earn interest elsewhere.
Similarly, yield-bearing stablecoin protocols allow users to deposit assets—such as other stablecoins like USDC or cryptocurrencies like BTC and ETH. The protocol then invests these resources into various yield-generating strategies and mints a stablecoin that represents the user’s deposit. Returns are distributed proportionally to stablecoin holders.
The sources of yield for these stablecoins vary. Some projects simply lend out deposited resources to earn interest, much like traditional banks. However, recent advancements in blockchain technology have introduced more innovative methods for generating yield.
Why Yield-Bearing Stablecoins Matter
Although stablecoins are a relatively new asset class, yield-bearing stablecoins are poised to become a fundamental part of DeFi. Here’s why they are so important:
Stablecoin Reserves Represent a Major Source of Yield
Stablecoins like USDC and USDT are directly pegged to fiat currencies and backed by reserves held in banks. These reserves, which amount to billions of dollars, generate significant yield. For instance, as of 2024, Circle (the issuer of USDC) held $33.9 billion in reserves, while Tether (the issuer of USDT) held $70 billion. These funds are deposited in banks and invested in low-risk assets like government bonds, generating interest. However, this yield is not passed on to USDC or USDT holders—it is retained by the issuing companies.
The yield potential of these reserves is substantial. For example, even a 2% annual yield on $70 billion would generate $1.4 billion in interest. If distributed to stablecoin holders, this could provide considerable returns and increase the attractiveness of holding these assets.
Inflation and Value Erosion
Between 2022 and 2024, inflation reached multi-decade highs, prompting central banks to raise interest rates aggressively. In 2022, the U.S. Consumer Price Index (CPI) grew at an annual rate of approximately 7%, and interest rates remained elevated in subsequent years. While higher interest rates on government debt help counteract the loss of fiat value due to inflation, stablecoin holders did not benefit from these improved yields. As a result, the value of stablecoin holdings depreciated faster than equivalent fiat currency placed in interest-bearing traditional savings accounts or bonds.
Yield-bearing stablecoins address this issue by providing interest that helps offset inflation, preserving purchasing power over time. This makes them a more attractive option for storing value in high-inflation environments.
Custody and Yield Generation
To earn yield from stablecoins, users often need to deposit assets into yield protocols like Aave, Maker, or Compound. This requires users to give up custody of their assets and often involves lock-up periods. Some protocols impose minimum lock-up periods to optimize yield generation, limiting flexibility for asset holders.
Yield-bearing stablecoins eliminate this inconvenience by allowing users to earn interest on idle funds directly from their wallets. Users retain full custody of their assets while generating returns. This enhances both security and flexibility, making it easier to manage assets without sacrificing potential yield.
Borderless Access to Risk-Free Returns
Risk-free returns, such as those offered by the U.S. Federal Reserve, are typically accessible only to U.S. citizens or entities with access to U.S. financial markets. Individuals outside these jurisdictions often face barriers to accessing safe yields. Yield-bearing stablecoins break down these jurisdictional restrictions, enabling anyone worldwide to benefit from risk-free returns in their preferred currency.
By tokenizing these yields, stablecoin protocols democratize access to safe, interest-bearing assets. They create new opportunities for individuals in regions with less stable financial systems, enabling them to earn reliable returns on their holdings and promoting greater financial inclusion.

How Do Yield-Bearing Stablecoins Generate Returns?
Yield-bearing stablecoins generate returns through various mechanisms, which can be broadly categorized into three primary sources: DeFi-native yield, crypto derivatives, and traditional finance (TradFi) combined with real-world assets (RWAs). Each category leverages different financial strategies and assets to create returns for stablecoin holders.
Below is a detailed explanation of each category, along with examples illustrating how they work.
DeFi-Native Yield
DeFi-native yield is generated through decentralized finance platforms that utilize the supply and demand dynamics of crypto assets like DAI, Ethereum, and Bitcoin. These platforms often use lending protocols to generate interest, which is then distributed to stablecoin holders.
- MakerDAO’s sDAI: The DAI Savings Rate (DSR) allows users to earn interest by depositing their DAI into the DSR contract. The sDAI token represents a deposit in this contract and accrues yield over time.
- Ethena Finance: This protocol uses a delta-neutral hedging strategy to generate yield from Ethereum while stabilizing the value of its stablecoin.
Crypto Derivatives
Crypto derivatives involve the use of liquid staking tokens and restaking tokens to generate yield. These derivatives are financial instruments whose value is derived from underlying crypto assets, such as staked Ethereum (ETH).
- Prisma Finance’s mkUSD: Backed by liquid staking derivatives, mkUSD earns staking rewards from underlying assets like ETH, which are passed on to holders.
- Davos Protocol’s DUSD: This stablecoin generates yield through restaking derivatives, a process where assets are staked multiple times to maximize returns.
TradFi and RWA
This category involves the tokenization of traditional financial assets to generate yield. These assets include government bonds, corporate debt, real estate, and other instruments commonly used in traditional finance.
- Ondo Finance and Flux Finance: These platforms generate yield by investing in traditional financial instruments and RWAs. The investments are tokenized and managed on the blockchain, providing stable returns to holders.
- Mountain Protocol: By investing in a combination of traditional financial assets and RWAs, this protocol offers consistent yields to its token holders.
- stEUR: This euro-denominated stablecoin uses a tokenized money market fund to generate yield, functioning similarly to MakerDAO’s DAI.
- Angle.money: This protocol generates yield by investing in a diversified portfolio of traditional financial assets.
- sUSDT and eUSDC: Tether’s sUSDT and Circle’s eUSDC generate yield by investing in assets like treasury bills and corporate bonds.
- BlackRock’s BUILD Fund: This fund invests in a wide range of traditional financial assets, with tokenized returns distributed to stablecoin holders.
- Paxos Lift Dollar: This stablecoin generates yield through investments in traditional financial instruments, offering stable and secure returns.
Each category offers unique advantages and opportunities for stablecoin holders, allowing them to generate returns while maintaining exposure to stable assets. The yield and risk profile of each category vary based on market conditions.
Risks Associated with Yield-Bearing Stablecoins
While yield-bearing stablecoins offer an appealing combination of yield and stability, they are not without risks. These include risks similar to those faced by traditional stablecoins, as well as unique risks associated with their yield-generation mechanisms. Below are the key risks to consider:
Inconsistent Yields
The yields generated by these stablecoins may not always be consistent. Several factors can affect returns, including:
- Market Volatility: Extreme market conditions can strain yield-generation mechanisms, leading to reduced returns.
- DeFi Protocol Risks: If yield is sourced from DeFi platforms, issues like smart contract bugs, hacks, or changes in protocol parameters can impact returns.
Collateral Depreciation
The collateral backing these stablecoins and their yields may depreciate significantly, especially if it consists of volatile crypto assets. Such depreciation can threaten both yield generation and the stability of the peg.
- Crypto Asset Volatility: If collateral includes assets like Ethereum or Bitcoin, a sharp decline in their value could reduce yields and destabilize the stablecoin.
- Liquidation Risk: In cases where collateral value drops substantially, automatic liquidation mechanisms in DeFi protocols may trigger, potentially causing losses for stablecoin holders.
Regulatory Risks
Yield-bearing stablecoins may attract regulatory scrutiny for several reasons:
- Competition with Traditional Banks: If these stablecoins offer higher returns while using similar risk assets, they could draw depositors away from traditional banks. This may disrupt the traditional financial system and prompt regulatory intervention.
- Compliance and Legal Challenges: Like all financial products, yield-bearing stablecoins must comply with existing and future regulations. Any regulatory changes or legal challenges could impact their operations and viability.
Smart Contract and Security Risks
Any blockchain-based financial product is exposed to smart contract risks:
- Bugs and Vulnerabilities: Yield-bearing stablecoins that rely on smart contracts are susceptible to coding errors. Exploits could lead to loss of funds or yield.
- Security Breaches: Hacks or security vulnerabilities in platforms that provide yield could compromise the assets backing the stablecoins, affecting both returns and stability.
Liquidity Risks
Yield-bearing stablecoins may face liquidity issues under certain conditions:
- Market Conditions: During periods of market stress, liquidity for these stablecoins may dry up, making it difficult for holders to sell or redeem their assets without significant slippage.
- Redemption Risk: If a large number of users attempt to redeem their stablecoins simultaneously, the underlying assets may lack sufficient liquidity to meet demand promptly, leading to delays or losses.
Yield Sustainability
The sustainability of the yields offered by these stablecoins is another critical risk:
- Reliability of Yield Sources: The sources generating yield may vary in reliability. If a yield source dries up or becomes less profitable, the stablecoin may fail to deliver expected returns.
- Economic Conditions: Broader economic conditions can impact yield sustainability. For example, low interest rates in traditional finance may reduce returns on real-world assets backing stablecoins.
