For a long time, the core role of stablecoins in the market was more like on-chain USD settlement tools: they served as transaction media, safe-haven assets, cross-border transfer mediums, and foundational liquidity for DeFi. They are the most important “silent infrastructure” in the crypto ecosystem. But after 2026, a deeper structural differentiation has begun in this sector: more and more funds are no longer satisfied with “holding USD-pegged assets,” but are seeking “on-chain USD assets that can continue to generate yield, be collateralized, nested, and participate in strategic combinations.”
CoinFound’s latest research, “On-Chain ‘Yu’e Bao’ Moment: Liquidity Migration Behind the Surge of Yield-Generating Stablecoins,” points out that yield-bearing stablecoins have moved from a marginal category to rapid growth. As of mid-March 2026, the total global stablecoin market cap is approximately $320 billion; the yield-bearing stablecoin market size is about $22.7 billion, a significant expansion from around $11 billion six months earlier, and their share of the overall stablecoin market has risen from about 4.5% to approximately 7.4%.
This is not just a typical market rotation, nor is it simply about “short-term high-yield products attracting quick capital.” On a deeper level, this is a liquidity migration centered around capital efficiency, control over funds, and on-chain asset management logic.
Why have yield-bearing stablecoins nearly doubled in half a year?
On the surface, many would naturally conclude: because they offer higher yields.
But this conclusion only explains the phenomenon, not the structure.
In the market environment of March 2026, centralized exchanges and traditional compliant platforms can also offer stablecoin yield products with attractive returns. Leading platforms targeting assets like USDC, USDe, and others can even provide quite appealing APRs at certain stages. For ordinary users, these products have clear advantages: lower thresholds, simpler operations, no need to manage private keys, and no exposure to on-chain interactions, gas costs, or smart contract risks.
If the market were purely driven by profit-seeking, theoretically, funds should stay more in exchange-based financial products rather than delve into on-chain environments with higher complexity and risk.
But the reality is quite the opposite—over $22.7 billion in funds are continuously migrating into yield-bearing stablecoins.
This indicates that the true driver of this explosion is not just superficial yields, but a higher layer of compound capital efficiency.
The core is not “high interest,” but “yield + liquidity + composability”
Traditional CEX yield models are essentially closer to “static deposits.”
Users deposit funds to earn fixed or floating returns, but in doing so, they give up the liquidity and usage rights of those funds. Funds in such financial states usually cannot be used as collateral for derivatives, continue providing liquidity to DeFi protocols, or be repeatedly used in lending, yield splitting, or leverage cycles.
The underlying design of yield-bearing stablecoins changes exactly this.
They encapsulate “yield rights” directly into the token itself, making these assets not just yield-generating vehicles but also “dynamic building blocks” on-chain that can be further collateralized, nested, lent, traded, and reassembled.
In other words, users are not holding a static USD, but an asset that can continue to generate yield and participate in on-chain capital operations.
This is the real underlying logic behind this liquidity migration:
Funds are not just after 4%, 5%, or 8% superficial yields, but want to hold an asset while still retaining all on-chain liquidity and strategic space.
Such assets can:
- Serve as collateral in lending protocols
- Be split into principal and yield rights for trading
- Be used as margin in derivatives
- Embed into protocol treasuries and DAO balance sheets
- Loop between multiple protocols to amplify capital efficiency
In other words, yield-bearing stablecoins are not the “end pool” of on-chain funds but a new launchpad.
The main players in this migration are not retail investors but professional on-chain capital
From the capital profile, the driving forces behind the surge in yield-bearing stablecoins are not scattered retail investors but two core groups:
1. Professional DeFi players
This type of capital is highly sensitive to “capital efficiency.”
They are not satisfied with single-source yields but prefer to use yield-bearing stablecoins as core collateral, injecting them into lending or yield trading protocols, and amplifying yield exposure through nested and structured strategies.
In this system, the importance of yield-bearing stablecoins is not just “being able to generate yield,” but that they are both the yield base and the strategic fuel that can be called upon.
2. Native on-chain institutions and protocol treasuries
DAO treasuries, protocol reserves, on-chain funds, and quantitative market makers are also accelerating their adoption of these assets.
The reason is simple: they need a cash management tool that can be directly held and utilized on-chain, with some yield, liquidity efficiency, and relative stability.
For these institutions, funds cannot be long-term parked in non-yielding stablecoins, nor is it suitable to rely solely on CEX-based financial products. The emergence of yield-bearing stablecoins fills the gap for “money market-like” assets in the on-chain world.
Who is absorbing this hundreds-of-billions liquidity wave?
Currently, the core players in this sector are mainly native crypto systems represented by USDS / sUSDS, USDe / sUSDe, while products like USYC, BUIDL, USDY form adjacent paths for on-chain USD yield assets.
Although both are competing for “on-chain USD yield funds,” their legal structures, compliance attributes, and product positioning are not identical.
Three main yield paths: where does the money come from?
This is the most critical question in the market.
The $22.7 billion in yields behind this scale cannot simply appear out of thin air. CoinFound summarizes the main current paths into three categories:
Path 1: RWA Mapping Model
This path centers on traditional financial assets like U.S. short-term government bonds and bank overnight repos.
Essentially, it maps real-world USD interest income into the chain via trusts, funds, or tokenization structures.
Characteristics include:
- Relatively stronger compliance
- Risks closer to traditional USD cash management tools
- Clear sources of yield, mainly from U.S. debt interest and money market returns
As shown in the first diagram, this path’s core is:
Money comes from real-world USD coupon payments.
Path 2: Delta-Neutral / Synthetic USD
This is the most crypto-native, complex, and flexible path.
Its core idea is to package spot or staked assets with derivatives and short positions to create a synthetic asset approximately pegged to USD.
Yields mainly come from:
- Underlying staking rewards
- Funding rates / basis profits in perpetual or futures markets
Representatives include systems like Ethena.
Its advantages are:
- Highly composable
- Greater yield elasticity
- Easier to embed into DeFi ecosystems
But its yields depend more on market structure, leverage demand, and derivatives liquidity.
It performs better in bull markets and faces more pressure when markets cool.
Path 3: On-Chain Native Staking
This path directly relies on staking rewards from PoS blockchains.
Issuers use financial engineering to transform ETH and other native assets’ staking returns, through hedging and re-encapsulation, into more stable dollarized yield tools.
It does not depend on U.S. debt coupons nor solely on funding rates, but more directly on the blockchain system’s “consensus rewards.”
The leading landscape has already formed, and supply-side concentration is underway
From the current sector landscape, the top players are relatively clear.
Sky (USDS / sUSDS)
Sky is one of the closest to an “internal protocol bank” among yield stablecoins.
Its moat is not just scale but the integration of stablecoins, savings rates, collateral systems, and DeFi composability within a single protocol framework, creating strong systemic stickiness.
Ethena (USDe / sUSDe)
Ethena is the most representative player in the synthetic USD path.
Its real strength lies in deep integration with DeFi infrastructure like Aave and Pendle, making USDe / sUSDe not just yield products but also high-frequency collateral and strategic assets within the DeFi ecosystem.
Circle USYC
USYC is closer to an on-chain money market fund rather than a narrow yield stablecoin.
Its strength is not just higher yields but leveraging Circle’s B2B channels and institutional distribution to penetrate institutional cash management and margin scenarios.
BlackRock BUIDL
BUIDL is a typical institutional on-chain fund product.
It represents traditional asset managers bringing USD cash management products on-chain, more suitable as a large institution’s on-chain parking asset rather than a general-purpose payment stablecoin.
Ondo USDY
USDY offers on-chain yield note exposure, targeting global, multi-chain distribution and long-tail markets.
It also competes for on-chain USD yield funds but has legal attributes closer to a note-like asset rather than a stablecoin.
The market is undergoing structural differentiation: payment layer vs. asset management layer
More importantly, the rise of yield-bearing stablecoins does not mean they will completely replace USDT or USDC.
Instead, the market is moving toward a clearer layering:
- Traditional payment stablecoins: further converging into payment and settlement layers
- Yield-based on-chain USD tools: gradually taking on fund management and wealth storage functions
This indicates that the stablecoin market is shifting from the past “one asset serving all functions” to a layered structure similar to traditional finance:
- One layer for circulation
- One layer for storage and appreciation
- One layer for institutional cash management and yield harvesting
Yield-bearing stablecoins do not eliminate traditional stablecoins,
but they are reshaping the boundaries, functions, and profit distribution of on-chain USD assets.
Regulatory-driven functional layering and interest spread reallocation
This change is not just market-driven but also deeply influenced by regulatory factors.
As the US and Hong Kong stabilize their stablecoin frameworks, payment stablecoins are increasingly restricted to “payment pipelines.”
Under this regime, payment stablecoins emphasize:
- Fully backed by high-quality liquid assets
- Redeemable at face value
- Prohibiting direct interest payments to holders
This means that the long-held reserve interest spread of traditional stablecoin issuers is facing new challenges.
In the past, ordinary holders bore asset and credit risks but could not share in interest income; with the emergence of yield-bearing on-chain USD tools, a new profit redistribution mechanism is forming:
Some reserve income that previously belonged to issuers is now redistributed to holders and on-chain capital.
This is one of the deepest institutional significances of yield-bearing stablecoins.
Conclusion: The on-chain “Yu’e Bao” moment is already prefigured on the institutional side
Looking back from March 2026, the $22.7 billion moved by yield-bearing stablecoins over the past half year is not an isolated figure.
It reflects a shift in crypto capital consciousness: funds are no longer content with holding a “static USD,” but are seeking a “dynamic USD” that can preserve value, generate yield, and participate continuously in on-chain strategies.
This is the “Yu’e Bao” moment in the on-chain world.
It does not mean traditional payment stablecoins will lose their position, nor that all on-chain USD will become yield-generating.
But it clearly shows that future competition in the stablecoin world will no longer be just about scale or payment networks, but about:
Who can serve as the store of on-chain wealth, who can offer higher capital efficiency, and who can find better balances between compliance and composability.
