The Rise of Yield-Generating Stablecoins: From Digital Dollars to Market Restructuring of Interest-Bearing Assets

Stablecoins are undergoing a structural bifurcation.
If 2025 is the milestone year when stablecoins evolve from crypto trading tools to foundational payment infrastructure, then the changes in the first quarter of 2026 are even more profound: stablecoins are no longer just “digital dollars,” they are beginning to transform into “digital deposit substitutes” that can generate annualized yields.

Data shows that yield-bearing stablecoins grew by 22% in Q1 2026, adding approximately $4.3 billion in market value, contributing over half of the net increase in the entire stablecoin industry.
sUSDS single asset absorbed over $2.5 billion in new funds, surpassing the combined total of the next four yield-bearing stablecoins; at the same time, USDY’s market cap increased by over 150%.
Meanwhile, U.S. banking industry is launching a high-intensity lobbying campaign, attempting to enshrine a ban on “yield-bearing stablecoins” into federal law.
IMF and BIS have also issued risk warnings, directly linking the growth of yield-bearing stablecoins to macrofinancial stability.

Are yield-bearing stablecoins an innovative breakthrough for inclusive finance, or a systemic risk accumulation point outside the traditional banking system?

How Yield-Bearing Stablecoins Are Becoming the Center of Regulatory Storms

Yield-bearing stablecoins are digital assets that maintain a dollar peg while distributing yields to holders.
Their sources of yield include: interest from U.S. Treasuries, DeFi protocol lending income, market-making strategy returns, and derivatives strategy revenues.

In Q1 2026, this sector experienced significant growth.
The total market cap of stablecoins officially crossed $320 billion in May, with USDT accounting for about $189.5 billion, holding a 58.76% market share.
Among them, yield-bearing stablecoins added about $4.3 billion in market value over three months, with sUSDS single asset attracting over $2.5 billion in new funds—more than the combined total of the next four yield-bearing stablecoins.
USDY’s market cap also grew by over 150%.

The rapid expansion of yield-bearing stablecoins directly triggered political backlash from U.S. banks.
The American Bankers Association, together with five major lobbying groups, pressured the Senate to fully ban stablecoin issuers from offering any form of yields or rewards.
The debate over the “legality of yield-bearing stablecoins” is now shaping a high-intensity policy confrontation in Washington.

From the GENIUS Act to Escalating Bank Lobbying

On July 18, 2025, the U.S. President signed the GENIUS Act, establishing a federal regulatory framework for payment stablecoins, requiring issuers to hold 1:1 full reserves, and completing redemptions within two business days.
The law also explicitly states that payment stablecoin issuers cannot directly pay interest to holders—a clause that foreshadows future policy disputes.

However, the “no interest” clause in the GENIUS Act is considered to have ambiguous enforcement space.
The crypto industry quickly circumvented the ban through “reward” mechanisms: formally not called “interest,” but effectively close to annualized yields.
From March to May 2026, legislative efforts around the CLARITY Act (Digital Asset Market Clarity Act) made the legal status of yield-bearing stablecoins a core controversy.
OCC has issued proposed rules explicitly banning issuers from paying interest, yields, or rewards to holders.

In March 2026, the Senate reached a preliminary compromise on stablecoin yield issues, banning “passive balances” from earning rewards but allowing yield distribution in “active user” scenarios.
In May, six top banking trade groups demanded the complete removal of this exception, citing that the compromise created “loopholes.”
As of May 18, the final text of the bill had not yet been settled.

Meanwhile, in April 2026, FinCEN and OFAC jointly released a draft implementing regulation to strengthen AML and sanctions compliance obligations for PPSI, requiring issuers to establish independent AML/CFT programs and undergo ongoing audits and third-party verification.

This legislative process reveals a clear game chain: first bans, then circumvention; first compromises, then pressure for amendments.
Behind each step are structural conflicts of interest between traditional banking and the native crypto industry.
This contest is not over, and its outcome will have profound implications for the business models of the stablecoin sector.

Growth Drivers and Structural Fragility of Yield-Bearing Stablecoins

Growth Engine: Who Is Driving the Expansion of Yield-Bearing Stablecoins

From market cap distribution, the yield-bearing stablecoin sector is highly concentrated.
sUSDS dominates with over $2.5 billion inflow in a single quarter, while the combined increase of the next four yield-bearing assets is less than that of sUSDS alone.

In terms of yield levels, there are significant differences among assets.
As of January 2026, Ethena’s sUSDe annualized yield ranged from 4% to 18%, dropping to about 4% by May.
Aave’s sGHO was around 5%–9%, Sky’s USDS about 4%–11%, and Ondo Finance’s USDY about 3.7%–5.3%.
These yield differences reflect vastly different risk sources:

• U.S. Treasury-based (USDY, USDS): yields come from U.S. Treasury interest, essentially tokenized money market funds
• DeFi protocol-based (sGHO): yields from lending market interest
• Derivative strategy-based (sUSDe): yields from ETH staking rewards and futures funding rates, relying on complex market conditions

It’s worth noting that traditional non-yield stablecoins still dominate the entire market.
USDT and USDC together account for about 85% of the market share.
This means that although yield-bearing stablecoins are growing rapidly, their overall size remains limited—this sub-sector is currently valued at about $3.7 billion, far below the entire stablecoin market of around $300 billion.

Structural Fragility: Historical Cases of Depegging

While expanding, yield-bearing stablecoins have a history of risks.
The collapse of Terra’s algorithmic stablecoin UST in 2022, with about $40 billion evaporating in 72 hours, left a deep scar in the industry.
In the Silicon Valley Bank incident of 2023, USDC briefly depegged to about $0.87 due to roughly $3.3 billion reserves held at SVB, exposing counterparty risk in fiat-backed stablecoins.
In 2025, the synthetic yield stablecoin xUSD lost about $93 million of Stream fund assets and depegged to about $0.26.

On March 22, 2026, the Delta-neutral stablecoin USR was hacked, with attackers leaking private keys to illegally mint about $80 million of asset-backed tokens, causing USR to plummet to about $0.025 on Curve.

The commonality in these cases: the more complex the yield mechanism, the easier it is to accumulate hidden risk exposures.
Derivative strategy stablecoins’ yields are highly dependent on market conditions—performing well in a bull market with positive funding rates, but facing enormous pressure in a bear market when rates turn negative.
sUSDe’s yield rate, which peaked at over 20% during the 2024 bull market, has fallen to about 4% by May 2026, exemplifying this structural fragility.
This “bull market friendly, bear market exposed” characteristic creates an inherent tension with truly stable assets.

Bank Lobbying vs. Crypto Industry Interests: A Full Picture

Core Arguments from Banks

The American Bankers Association (ABA) has prioritized curbing the growth of yield-bearing stablecoins in 2026.
A coalition of six major banks opposes the compromise wording in the CLARITY Act, claiming it creates “loopholes.”
Research cited by banks suggests that banning stablecoin yields entirely would increase bank loans by $2.1 billion, with community banks adding $500 million.

A leaked one-page document titled “Principles of Yield and Interest Prohibition” from a White House meeting states that banks insist no stablecoin yields or incentives should be allowed, claiming such yields threaten core deposit business.

The core argument from banks:
Yield-providing stablecoins are essentially unregulated deposit tools, and issuers, without deposit insurance or capital requirements, are engaging in “regulatory arbitrage” against banks.

This argument relies on “regulatory asymmetry”:
The compliance costs for stablecoin issuers versus banks differ greatly when both accept public funds.
While seemingly reasonable, it sidesteps a key issue—if banks could offer attractive interest rates, deposit outflows wouldn’t be so significant.
In other words, banks attribute “regulatory arbitrage” to their competitors, ignoring their own “systemic rent” in a low-interest environment.

Crypto Industry’s Core Arguments

Coinbase’s Chief Policy Officer Faryar Shirzad characterizes the bank lobbying proposals as “killing competition,” describing ongoing legislative efforts as a “15-round heavyweight championship” against banking lobbies.
The crypto industry is actively shaping the debate through strategic frameworks.

Crypto’s stance is based on “consumer sovereignty”: restricting yield-bearing stablecoins essentially deprives ordinary people of asset appreciation options.
This argument has natural public support in a low-interest environment.

However, there is a weak point: it treats all yield-bearing stablecoins as equivalent, ignoring the vastly different risk profiles of assets derived from U.S. Treasuries, derivatives strategies, or DeFi lending.
Not all “yield-bearing stablecoins” share the same risk characteristics.

Third-Party Observers

International institutions view this contest from a broader macro perspective.
IMF’s Tobias Adrian sees “dollarization” as the primary challenge posed by stablecoins, warning it could threaten monetary sovereignty.
BIS’s Agustín Carstens warns that diverging regulatory paths could lead to severe market fragmentation or harmful regulatory arbitrage.

Industry Impact Analysis: From Deposit Competition to Traditional Finance’s Adaptive Response

Traditional Financial Institutions’ Response: Morgan Stanley MSNXX Fund

A key industry signal: on April 23, 2026, Morgan Stanley’s asset management arm MSIM announced the launch of the “Stablecoin Reserve Portfolio Fund” (MSNXX), a government money market fund designed to meet the reserve investment requirements under the GENIUS Act.

The fund has a minimum investment of $10 million, a management fee of 0.15%, and invests solely in U.S. Treasuries and repos collateralized by government securities, aiming to maintain a $1 net asset value.

This event is more than a product development—it indicates that traditional finance’s attitude toward stablecoins is shifting from “opposition” to “service and participation.”
Morgan Stanley’s involvement in both Bitcoin trusts and stablecoin reserve funds shows a view of digital assets as a long-term strategic direction.
Yet, whether a reserve fund managed by a traditional investment bank aligns with the “decentralized” ethos of crypto remains a structural tension worth ongoing observation.

Evolution of the Crypto Industry Itself

According to estimates by McKinsey and Artemis Analytics, stablecoin B2B transfers have reached about $226 billion, making it the largest and fastest-growing stablecoin category.
On-chain data shows that DEX liquidity provision, withdrawals, flash loans, and lending activities constitute the main on-chain uses, while retail payment demand remains limited in proportion.

Between March and April 2026, on Tron and Ethereum chains, the number of new frozen USDT and USDC addresses was about 1,397, with a total frozen amount of roughly $722 million, and total historical transaction volume of frozen addresses exceeding $25 billion.
On-chain regulatory enforcement is rapidly intensifying.

Conclusion

Yield-bearing stablecoins are at a critical institutional juncture.
On one hand, their 22% quarterly growth and 4%–8% annualized yields indicate genuine and deep market demand, not just speculative narratives.
On the other hand, ongoing bank lobbying, IMF/BIS warnings about “digital dollarization,” and repeated historical depegging events show that these products carry non-trivial risks.

The key question for global regulators is: how to balance risk suppression with innovation encouragement?
For industry participants, an honest acknowledgment is necessary—that not all “yield-bearing stablecoins” are equally safe and sustainable.
There are significant risk differences between U.S. Treasury-based products and derivatives strategies.

Regardless of the final legislative direction, yield-bearing stablecoins have irreversibly changed the definition of “stablecoins”—they are no longer just payment tools but are becoming a structural element with yield attributes within the global digital financial infrastructure.
