What signals are conveyed by the latest draft from the U.S. Senate Banking Committee regarding the compliant path for stablecoin interest-earning functions?

The regulatory uncertainty surrounding the stablecoin market is approaching a critical turning point. On May 14, 2026, the U.S. Senate Banking Committee officially approved the latest revised draft of the "Digital Asset Market Clarity Act" (CLARITY Act) with a vote of 15 in favor and 9 against, and submitted it to the full Senate for review. This long-standing bill, which has been stalled over stablecoin yield disputes, finally takes a substantive step forward. However, what is truly noteworthy is not the vote itself, but the newly added provisions in the draft concerning DeFi and yield rewards—they are redefining the functional boundaries of stablecoins in the crypto economy and opening the door to a new phase called the "regulatory sandbox."

How the Latest Bill Draft Reshapes Stablecoin Yield Functions

The most contentious part of the CLARITY bill draft centers on Section 404, which defines stablecoin yield arrangements. The latest language is very clear: it prohibits passive interest or returns based on static coin holdings, but explicitly permits incentive-based rewards tied to real economic activities. The former includes annualized returns simply earned by holding stablecoins; the latter covers cashback payments, trading discounts, staking incentives, and rewards linked to consumer behavior. This distinction, for the first time at the legal level, dissects stablecoin yield functions into two dimensions: "passive income" and "behavioral rewards." The former is categorized alongside traditional bank deposit interest and thus subject to strict restrictions; the latter is viewed as a compliant commercial method to promote payment network activity.

Why Static Yield Has Become the Core Red Line in Legislation Battles

From a legislative perspective, the reason why static stablecoin yields are at the center of contention is that they touch on the most sensitive competitive boundary between traditional banking systems and crypto finance. Banking lobbying groups have submitted numerous letters to the Senate explicitly stating that allowing non-bank entities to pay yields close to bank deposit interest on stablecoin holdings would constitute "unregulated deposit outflows," directly impacting deposit insurance systems and bank liquidity management. Previously, some exchanges offered annualized yields of 4-5% on USDC holdings, while bank deposit rates were generally very low. This interest rate gap drove large amounts of funds from traditional accounts into crypto platforms. From a regulatory logic standpoint, Section 404 essentially draws a competitive red line: any stablecoin yield model that functionally equals bank deposit interest must operate within a prudential regulatory framework equivalent to that of banks. Stablecoin issuers and trading platforms without banking licenses cannot participate in deposit competition through "interest-like" mechanisms.

Opportunities and Constraints for DeFi Protocols Under the Compliance Framework

The draft’s treatment of DeFi reflects a cautious approach to differentiated regulation. According to the disclosed revisions, fully decentralized DeFi protocols may be exempted from SEC registration under certain conditions, and developers and validators are granted limited regulatory exemptions. This means that deeply decentralized lending protocols and decentralized exchanges can continue to operate at the core protocol level. However, the constraints are also clear: activities that can be linked to stablecoin reward mechanisms are strictly limited to payments, trading, staking, and other real economic activities; purely holding-based yield models are thoroughly excluded. Additionally, the Senate version tightens the definition of "decentralized," excluding protocols with centralized governance structures or those dominated by a few entities.

Market research firm 10x Research notes that if the bill passes, the most directly affected will be DeFi tokens whose core selling point is "yield"—including projects like Uniswap, Aave, Compound, etc. This is not because these projects are illegal per se, but because their embedded yield distribution mechanisms may fall under the regulatory scrutiny of "interest-like functions" in the bill.

Deep Business Logic Behind Yield Restrictions and Reconstructed Settlement Channels

Beyond specific clause restrictions, the CLARITY Act, together with the GENIUS Act which took effect in July 2025, forms a larger institutional framework. The GENIUS Act establishes a federal issuance framework for payment stablecoins—requiring 1:1 full reserves, monthly disclosure of reserves, and redemption capabilities within two business days—placing compliant payment stablecoins outside the definition of securities. When viewed together, the institutional intent becomes clearer: the U.S. is transforming stablecoins from a role primarily as exchange balances and DeFi collateral into a regulated payment settlement infrastructure. From this perspective, banning static yield earning is not merely regulatory suppression but an effort to decouple stablecoins from savings functions, restoring their core identity as "digital cash." The global competitive edge of compliant stablecoins will no longer depend on high yields but on settlement efficiency, regulatory credibility, and channel coverage. Future market segmentation may look like this: large compliant stablecoins leveraging federal licensing advantages to penetrate traditional payments and cross-border settlement; native or offshore stablecoins continuing to serve DeFi liquidity markets but facing higher compliance costs and regulatory scrutiny.

The Institutional Synergy Between the GENIUS and CLARITY Acts

From a timeline and functional division perspective, the GENIUS and CLARITY Acts form a two-tiered, coordinated institutional system. The GENIUS Act focuses on the issuance side—who can issue, how reserves are managed, AML compliance, consumer protection, and monthly disclosures. Its core question is: who is qualified to issue regulated payment stablecoins, and how to ensure reserve safety and market integrity post-issuance. The CLARITY Act, on the other hand, covers broader market structure issues—including classification standards for digital assets (securities under SEC, commodities under CFTC), secondary market trading rules, legal positioning of DeFi protocols, and the delineation of yield boundaries in different applications. In other words, the GENIUS Act answers "what is a stablecoin," while the CLARITY Act addresses "what stablecoins can do and how." Analyzing both within the same framework helps grasp the full institutional evolution of U.S. stablecoin policy.

How the Market Size and Endogenous Demand of Stablecoins Influence Legislative Trends

The size of the stablecoin market makes this legislative discussion far beyond internal industry concerns. As of May 20, 2026, the total global market cap of stablecoins exceeds $321 billion, with USDT around $189.6 billion and USDC approximately $76.7 billion. This scale means that any regulatory changes affecting stablecoin yields or functions will directly impact liquidity of over $300 billion in digital assets. From a demand perspective, the intrinsic motivation of stablecoin holders to seek yield does not disappear due to legislative restrictions. If compliant stablecoins are stripped of yield attributes, some liquidity may migrate to offshore or native on-chain stablecoins with looser regulation. This is why the CLARITY Act does not completely shut down all yield channels but retains some flexibility through "permissible behavioral rewards."

The "Regulatory Sandbox" Approach for Developing Compliant Yield Pathways

The draft’s differentiated treatment of DeFi and the retention of behavioral rewards reflect a "regulatory sandbox" methodology. It does not outright ban all yield arrangements in stablecoins but establishes a compliance framework across three core dimensions to balance predictability and innovation: first, distinguishing passive income from behavioral rewards; second, defining the competitive boundary between traditional banks and crypto platforms; third, applying differentiated regulation based on the degree of decentralization. In practice, compliant yield pathways may evolve in three directions: highly decentralized DeFi protocols gaining greater regulatory exemptions; traditional financial institutions launching tokenized financial products as new compliant yield vehicles; and real economic activity-linked incentives for payments and trading experiencing systemic growth. Evidence of this trend is already emerging—U.S. money market funds are beginning to explore tokenized products to meet stablecoin issuer reserve management needs, laying foundational infrastructure for a compliant yield ecosystem.

Summary

On May 14, 2026, the U.S. Senate Banking Committee’s bipartisan approval of the CLARITY Act draft marks a new stage in U.S. stablecoin regulation—shifting from the issuer-focused rules under the GENIUS Act to market structure and usage scenario regulations under the CLARITY Act. The core logic of the draft is not to "ban" stablecoin yield functions but to differentiate passive income from behavioral rewards, seeking a balance between preventing deposit outflows and maintaining innovation in the crypto industry. For investors, projects, and infrastructure builders, understanding the three institutional dimensions—banning static yield, allowing behavioral incentives, and tiered DeFi regulation—is fundamental to grasping future compliance boundaries. Even if the bill still needs to go through full Senate review, House coordination, and presidential signing, its passage has already provided a clear institutional blueprint for the regulatory sandbox era in stablecoins.

Frequently Asked Questions (FAQ)

Q1: Does the CLARITY Act mean holding stablecoins will no longer generate any yield at all?

No. The bill prohibits passive interest—meaning yields solely earned by holding stablecoins. Incentive-based yields generated by real economic activities, such as cashback, trading discounts, staking rewards, and consumption-linked bonuses, remain permitted.

Q2: What specific impact does this bill have on DeFi protocols?

The impact is twofold. Fully decentralized DeFi protocols may be exempted from SEC registration under certain conditions, with developers and validators enjoying limited regulatory exemptions. However, if a protocol’s yield distribution mechanism functionally resembles bank interest, it may face higher compliance risks, especially for lending protocols and decentralized exchanges that emphasize yield as a core feature.

Q3: What are the differences between the CLARITY and GENIUS Acts?

The GENIUS Act mainly targets the issuance side—who can issue, how reserves are managed, AML compliance, and disclosure requirements. The CLARITY Act covers broader market structure issues—classification standards for digital assets, trading rules, DeFi legal positioning, and yield boundaries in various applications.

Q4: What stage is the bill currently at in the legislative process? When might it become law?

The draft has passed the Senate Banking Committee and is now under full Senate review. It still needs Senate floor votes, reconciliation with the House version, and presidential approval. Given the August congressional recess as a practical legislative window and active executive push, market expectations are that the bill could be finalized around summer 2026.

Q5: What is the expected impact of the bill on the stablecoin market size?

As of May 20, 2026, the total global stablecoin market cap exceeds $321 billion. Restrictions on passive yield may temporarily affect yield-dependent stablecoin models, but in the long run, compliant payment stablecoins with settlement functions and infrastructure value are likely to gain greater market recognition. The fundamental shift is repositioning stablecoins from savings assets to payment tools, which will profoundly influence future market competition.
