Stablecoins are undergoing a structural transformation. If 2025 marks the milestone when stablecoins graduate from crypto trading tools to payment infrastructure, then the changes in the first quarter of 2026 are even more profound: stablecoins are no longer just "digital dollars"—they are evolving into "digital deposit alternatives" that offer annualized yields.
Data shows that yield-bearing stablecoins grew by 22% in Q1 2026, adding approximately $4.3 billion in new market value and accounting for more than half of the net growth across the stablecoin sector. sUSDS alone attracted over $2.5 billion in new capital, surpassing the combined inflows of the next four yield-bearing stablecoins. Meanwhile, USDY’s market cap surged by more than 150%. At the same time, US banks launched an intense lobbying campaign, aiming to enshrine a "ban on yield-bearing stablecoins" in federal law. The IMF and BIS have issued risk warnings, directly linking the rise of yield-bearing stablecoins to macro-financial stability.
Are yield-bearing stablecoins a breakthrough for inclusive finance, or are they accumulating systemic risk outside the traditional banking system?
How Yield-Bearing Stablecoins Became the Center of Regulatory Storms
Yield-bearing stablecoins are digital assets that maintain a dollar peg while distributing returns to holders. Their sources of yield include US Treasury interest, DeFi protocol lending, market-making strategies, and derivatives income.
In the first quarter of 2026, this segment saw remarkable growth. The total stablecoin market cap crossed $320 billion in May, with USDT commanding about $189.5 billion and 58.76% market share. Yield-bearing stablecoins added roughly $4.3 billion in market value within three months, with sUSDS alone absorbing more than $2.5 billion—greater than the combined increase of the next four yield-bearing stablecoins. USDY’s market cap grew by over 150% during the same period.
The rapid expansion of yield-bearing stablecoins triggered a political backlash from US banks. The American Bankers Association, along with five major lobbying groups, pressured the Senate to ban stablecoin issuers from offering any form of yield or rewards. This battle over the "legitimacy of yield-bearing stablecoins" is escalating into a high-stakes policy confrontation in Washington.
From the GENIUS Act to Escalating Bank Lobbying
On July 18, 2025, the US President signed the GENIUS Act, establishing a federal regulatory framework for payment stablecoins. The law requires issuers to hold 1:1 full reserves and mandates redemption within two business days. It also explicitly prohibits payment stablecoin issuers from paying interest to holders—a clause that sowed the seeds for future policy disputes.
However, the GENIUS Act’s "interest ban" is seen as having ambiguous enforcement. The crypto industry quickly circumvented the restriction through "reward" mechanisms: not labeled as "interest," but effectively delivering annualized returns. From March to May 2026, as the CLARITY Act (Digital Asset Market Clarity Act) advanced through Congress, the legal status of yield-bearing stablecoins became a central point of contention. The OCC has issued proposed rules explicitly banning issuers from paying interest, yield, or rewards to holders.
In March 2026, the Senate reached a preliminary compromise on stablecoin yields: rewards for "passive balances" are banned, but yield distribution is allowed for "active user engagement." In May, six top banking trade groups demanded the removal of this exception, arguing it creates "loopholes for evasion." As of May 18, the final text of the bill remains unsettled.
Meanwhile, in April 2026, FinCEN and OFAC jointly released a draft for public comment, strengthening anti-money laundering and sanctions compliance for PPSI. Issuers must establish independent AML/CFT programs and undergo ongoing audits and third-party reviews.
This legislative process reveals a clear chain of contention: first comes prohibition, then evasion; first compromise, then pressure to revise. Each step reflects deep structural conflicts of interest between traditional banking and the crypto-native sector. The outcome of this struggle will profoundly impact the business models of the stablecoin industry.
Growth Drivers and Structural Vulnerabilities of Yield-Bearing Stablecoins
Growth Drivers: Who Is Fueling Yield-Bearing Stablecoin Expansion?
Market cap distribution shows that yield-bearing stablecoins are highly concentrated. sUSDS dominated with over $2.5 billion in inflows in a single quarter, while the next four yield-bearing stablecoins combined failed to match sUSDS’s growth.
Yield levels vary significantly across products. As of January 2026, Ethena’s sUSDe offered annualized yields between 4% and 18%, which fell to around 4% by May. Aave’s sGHO ranged from 5% to 9%, Sky’s USDS from 4% to 11%, and Ondo Finance’s USDY from 3.7% to 5.3%. These differences reflect distinct underlying risk sources:
- US Treasury-backed (USDY, USDS): Yield comes from US Treasury interest, essentially functioning as tokenized money market funds.
- DeFi protocol-based (sGHO): Yield derives from lending market interest.
- Derivatives strategy-based (sUSDe): Yield is generated from ETH staking rewards and futures funding rates, relying on complex market conditions.
It’s important to note that traditional, non-yield stablecoins still dominate the market. USDT and USDC together account for about 85% of market share. Despite rapid growth, yield-bearing stablecoins remain relatively small—currently valued at around $3.7 billion, far less than the $300 billion stablecoin market.
Structural Vulnerabilities: Historical Depegging Incidents
Yield-bearing stablecoins have expanded, but their historical risk cases cannot be ignored. In 2022, Terra’s algorithmic stablecoin UST collapsed, wiping out $40 billion in market value within 72 hours and leaving a lasting scar on the industry. In the 2023 Silicon Valley Bank incident, USDC briefly depegged to about $0.87 due to $3.3 billion in reserves held at SVB, exposing counterparty risk in fiat-backed stablecoins. In 2025, yield-bearing synthetic stablecoin xUSD depegged to about $0.26 after Stream Fund lost about $93 million in assets.
On March 22, 2026, stablecoin USR, which used a delta-neutral strategy, was hacked. Attackers exploited leaked private keys to illegally mint about $80 million in unbacked tokens, causing USR to crash to about $0.025 on Curve.
The common thread in these cases: the more complex the yield mechanism, the greater the hidden risk exposures. Derivatives-based stablecoins’ yields depend heavily on market conditions—they perform well in bull markets with positive funding rates, but face immense reserve pressure when rates turn negative. sUSDe’s yield dropped from over 20% during the 2024 bull market peak to about 4% in May 2026, illustrating this structural fragility. This "bull market friendly, bear market exposed" dynamic creates fundamental tension with the concept of a truly "stable asset."
Bank Lobbying vs. Crypto Industry: A Comprehensive Interest Conflict
Banks’ Core Arguments
The American Bankers Association (ABA) has made curbing yield-bearing stablecoin growth a top priority for 2026. An alliance of six major banking trade groups formally opposes compromise language in the CLARITY Act, arguing it creates "loopholes for evasion." Banks cite research showing that banning stablecoin yields would increase bank lending by $2.1 billion and community bank lending by $500 million.
According to a leaked White House meeting memo titled "Principles of Yield and Interest Prohibition," banks insist that no stablecoin should offer yield or incentives, claiming such returns threaten the core deposit business of the US banking system.
Banks’ main argument is that yield-bearing stablecoins function as unregulated deposit instruments. Issuers compete with banks in "regulatory arbitrage" without deposit insurance obligations or capital adequacy requirements.
The crux of the banks’ position is "regulatory asymmetry": both absorb public funds, but compliance costs for stablecoin issuers and banks differ dramatically. While this argument is reasonable, it sidesteps a key issue—if banks were competitive enough to offer attractive rates, the pressure of deposit outflows wouldn’t be so pronounced. In other words, banks blame "regulatory arbitrage" on unfair competition, but remain silent about the "systemic rent" created by their own low-rate environment.
Crypto Industry’s Core Arguments
Coinbase Chief Policy Officer Faryar Shirzad characterized the banks’ legislative proposals as "killing competition," describing the ongoing legislative battle as a "15-round heavyweight championship" against banking lobbyists. The crypto industry has released strategic frameworks to shape the debate around stablecoin yields.
The crypto side’s stance is rooted in "consumer sovereignty": restricting yield-bearing stablecoins essentially deprives ordinary people of opportunities to grow their assets. This argument naturally resonates in a low-rate environment.
However, the crypto industry’s reasoning has a weakness—it treats all yield-bearing stablecoins as equivalent, ignoring the vast differences in risk profiles among US Treasury-backed, derivatives-based, and DeFi lending stablecoins. Not all "yield-bearing stablecoins" carry the same risk.
Third-Party Observers
International organizations take a more macro perspective. IMF Monetary and Capital Markets Director Tobias Adrian defines "dollarization" as the primary challenge posed by stablecoins, warning, "For central banks, this could threaten monetary sovereignty." BIS General Manager Agustín Carstens cautions that divergent national regulatory approaches may 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 notable industry signal: On April 23, 2026, Morgan Stanley Investment Management (MSIM) announced the launch of the "Stablecoin Reserve Portfolio Fund" (MSNXX), a government money market fund specifically designed to meet GENIUS Act reserve investment requirements for stablecoin issuers.
The fund has a minimum investment of $10 million, a management fee of 0.15%, invests only in US Treasuries and government-backed repos, and aims to maintain a $1 net asset value.
This event goes beyond product innovation. It signals that traditional financial institutions are shifting from "opposition" to "service and participation" regarding stablecoins. Morgan Stanley is simultaneously investing in bitcoin trusts and stablecoin reserve funds, viewing digital assets as a long-term strategic direction. However, whether a reserve fund managed by a traditional investment bank is compatible with the "decentralized" crypto-native ethos remains a structural tension worth watching.
The Crypto Industry’s Own Evolution
According to estimates from McKinsey and Artemis Analytics, B2B stablecoin transfers have reached about $226 billion, making it the largest and fastest-growing stablecoin segment. On-chain data shows that DEX liquidity provision and withdrawal, flash loans, and lending activities constitute the main on-chain uses for stablecoins, while true retail payment demand remains limited.
Between March and April 2026, TRON and ETH chains saw about 1,397 new frozen USDT and USDC addresses, with a total of $722 million directly frozen and historical transaction volumes exceeding $25 billion. On-chain regulation is intensifying rapidly.
Conclusion
Yield-bearing stablecoins are at a critical point of institutionalization. On one hand, their 22% quarterly growth and 4%–8% annualized yields demonstrate genuine and deep market demand—not just speculative hype. On the other hand, persistent bank lobbying, IMF/BIS warnings about "digital dollarization," and repeated depegging incidents highlight that the risks are real and significant.
The core question for global regulators is: How can risk suppression and innovation encouragement be balanced? For industry participants, it’s equally important to honestly acknowledge that not all "yield-bearing stablecoins" offer the same safety or sustainability. There are substantial risk differences between US Treasury-backed products and derivatives-based products.
Regardless of how legislation ultimately unfolds, yield-bearing stablecoins have irreversibly redefined what "stablecoin" means—they are no longer just payment tools, but are becoming structural elements with yield attributes in the global digital financial infrastructure.
