"By focusing on the effects of a prohibition, the CEA paper risks creating a misleading sense of safety." — American Bankers Association, Response to White House Council of Economic Advisers Report, April 13, 2026
Six major jurisdictions now regulate stablecoin yield. None agree on how to do it. The result is a fragmented global framework where $315 billion in circulating stablecoins face different rules depending on where they are issued, held, and used — creating regulatory arbitrage opportunities that undermine the stated goals of each regime.
The European Union categorically bans yield under MiCA Article 22(4). The United States prohibits issuer-paid yield under the GENIUS Act but left a third-party loophole that the OCC is now attempting to close with a 376-page rulemaking. Hong Kong, which granted its first stablecoin licenses on April 10, 2026, bans yield tied to holding period or par value. The UAE mirrors this prohibition. Singapore restricts yield indirectly through business-activity limitations. Japan's Payment Services Act framework focuses on reserve composition rather than yield mechanics. The net effect: identical stablecoins generate different economics for holders depending on jurisdiction, while issuers forum-shop for the most favorable regulatory home.
At current interest rates, the reserve assets backing $315 billion in stablecoins generate an estimated $14–16 billion in annual interest income. The central question — who captures that value — remains answered differently by every major financial center.
Total stablecoin supply reached $315 billion in Q1 2026, according to CEX.IO and DefiLlama data — an $8 billion increase quarter-over-quarter. USDC supply stood at $78 billion, up 220% since late 2023. USDT contracted $3 billion to approximately $184 billion, its first quarterly decline since Q2 2022. Transaction volume hit $28 trillion in Q1, a 51% increase quarter-over-quarter and a new all-time high.
At a blended yield of approximately 4.5–5.0% on short-duration U.S. Treasuries and equivalent instruments, the reserve assets backing these stablecoins generate roughly $14–16 billion annually. This revenue currently accrues almost entirely to issuers. Tether reported $13.7 billion in operating profit for 2024. Circle, which went public at a $7 billion valuation via its June 2025 IPO, derives the majority of its revenue from USDC reserve yield.
The regulatory question is binary: should any portion of that $14–16 billion flow back to holders? Every jurisdiction that has addressed this question has answered "no" — but with different enforcement mechanisms, different exceptions, and different definitions of what constitutes prohibited yield.
MiCA Regulation (EU) 2023/1114, Article 22(4), prohibits asset-referenced token issuers from granting "interest or any other benefit related to the length of time during which a holder holds such asset-referenced tokens." The provision applies symmetrically to e-money tokens (EMTs) — the classification covering single-currency stablecoins like USDC and USDT.
The prohibition took effect for stablecoin issuers in June 2024. Broader crypto-asset service provider (CASP) licensing requirements became fully enforceable in January 2026. The final transitional period ends July 1, 2026, after which all entities must hold MiCA authorization to operate within the EU.
Implementation has been direct. Major crypto platforms disabled European stablecoin reward programs in 2024. The Oxford Law Blog's March 2026 analysis described MiCA's approach as "precautionary and stability-oriented," noting the EU's explicit concern that yield-bearing stablecoins could "accelerate deposit substitution" and "undermine banks' access to low-cost deposit funding."
The regime leaves no ambiguity and no loopholes. Third-party reward programs, affiliate structures, and activity-based incentives tied to stablecoin balances all fall within the prohibition's scope. The trade-off is clarity at the cost of consumer benefit — EU stablecoin holders receive zero return on holdings while issuers retain full reserve income.
The GENIUS Act, signed into law on July 18, 2025, prohibits permitted stablecoin issuers from paying "interest, yield, dividends, or other returns to holders based solely on holding a payment stablecoin." The statute targets issuers directly but does not clearly extend the prohibition to affiliated entities or third-party platforms.
This gap generated a lobbying war. More than 3,000 banks, led by the American Bankers Association (ABA), funded advertising campaigns urging Congress to "close the stablecoin loophole." Coinbase, which reported $1.35 billion in stablecoin-related revenue in 2025, restructured its USDC program as a "rewards" feature for Coinbase One subscribers at 3.5% APY — framing it as a loyalty incentive rather than interest.
The White House Council of Economic Advisers weighed in on April 8, 2026, with a 21-page analysis concluding that a yield prohibition would increase bank lending by $2.1 billion — a 0.02% increase — while imposing $800 million in annual consumer welfare costs. Even under worst-case assumptions (stablecoin market growing to six times its current deposit share, all reserves locked in unlendable cash, the Federal Reserve abandoning its current framework), additional lending would reach only $531 billion, a 4.4% increase. Community bank lending would rise by $129 billion, or 6.7%, under those implausible conditions.
The ABA responded on April 13, arguing the CEA "studied the wrong question" by analyzing yield prohibition effects rather than the consequences of permitting yield. The banking lobby warned that the stablecoin market could scale from $300 billion to $2 trillion if yield is allowed, with reserves concentrating in larger institutions rather than community banks.
The OCC published a 376-page proposed rule on February 25, 2026, targeting third-party yield arrangements. The rule creates a rebuttable presumption of violation when a stablecoin issuer has a contract with an affiliate or related third party that then passes yield to holders. Independent merchant discounts for using stablecoins are explicitly permitted; subscription-model yield programs are flagged as potential circumvention. Final regulations are targeted for July 2026.
The CLARITY Act, which would resolve these ambiguities legislatively, remains stalled. Senators Thom Tillis (R-NC) and Angela Alsobrooks (D-MD) reached a compromise in March: passive yields are prohibited, but rewards linked to payments, transfers, or platform usage are permitted. White House adviser Patrick Witt confirmed the deal on April 13. The Senate Banking Committee markup has slipped from April to May.
Circle's stock dropped 20% following the March 20 Tillis-Alsobrooks announcement. Coinbase fell approximately 10%.
Hong Kong's Stablecoins Ordinance (Cap. 656) took effect August 1, 2025. The HKMA received 36 applications in the first batch by the September 30, 2025 deadline. On April 10, 2026, it granted its first two licenses — to Anchorpoint Financial Limited and The Hongkong and Shanghai Banking Corporation Limited (HSBC).
The yield prohibition is explicit. Licensed stablecoin issuers cannot pay holders any interest or return based on: (a) the length of holding period, (b) par value, or (c) market value of the stablecoin. Reserve requirements mandate 100% backing by high-quality, liquid assets, segregated from the issuer's own funds.
HKMA Chief Executive Eddie Yue described the regime as providing "an orderly operating environment for stablecoin issuers." The framework positions Hong Kong as a licensing-first jurisdiction — allowing banks like HSBC to issue stablecoins while preventing them from competing with deposits via yield.
The practical effect: HSBC can issue a Hong Kong dollar stablecoin, earn yield on reserves, retain that yield, and offer the stablecoin for payment settlement — but cannot share any reserve income with holders. This mirrors the economic structure the GENIUS Act creates for U.S. issuers, minus the third-party loophole.
The Central Bank of the UAE (CBUAE) Payment Token Services Regulation (PTSR), effective July 6, 2024, explicitly prohibits issuers from paying interest or yield on payment tokens. Algorithmic stablecoins and privacy tokens are banned outright. The CBUAE approved its first USD-backed stablecoin in January 2026.
Merchant transition periods have ended — UAE retailers outside financial free zones must now accept only licensed dirham payment tokens. The regime extends to mainland UAE; financial free zones (DIFC, ADGM) maintain separate regulatory frameworks with potentially different treatment.
The UAE's approach aligns most closely with MiCA's categorical prohibition. No third-party workaround exists. The framework prioritizes payment utility over investment return, consistent with the CBUAE's stated goal of preserving stablecoins as settlement instruments.
Singapore's MAS Stablecoin Regulatory Framework, in force since August 2023, takes an indirect approach. Rather than explicitly banning yield, MAS restricts issuers to the "primary activity of SCS issuance," prohibiting exposure to risks from "other business services such as staking or lending, where interest is paid to customers." The practical effect is a soft ban: issuers cannot pay yield because doing so would fall outside their permitted business scope.
MAS is preparing draft stablecoin legislation in 2026 and plans to issue tokenized bills settled in central bank digital currency. Whether the legislative framework will formalize the yield prohibition or create permitted exceptions remains unresolved.
Japan's Payment Services Act classifies stablecoins redeemable in legal tender as "electronic payment instruments." Only banks, fund transfer service providers, and trust companies can issue them. The JFSA's April 2026 final guidelines focus on custody and reserve composition — specifically which foreign-issued bonds qualify as eligible collateral — rather than addressing yield mechanics directly. JPYC Co. launched the first fully regulated yen-pegged stablecoin in October 2025. A 2025 PSA amendment creating lighter registration for intermediaries takes effect by June 2026.
The UK represents the most permissive — or most indecisive — major jurisdiction. The Bank of England published consultation papers in December 2025 on regulating "sterling-denominated systemic stablecoins." The FCA is developing conduct standards, disclosure requirements, and platform rules, with final rules expected in 2026.
Yield is not explicitly prohibited. However, FCA guidance indicates that issuers will face limitations on passing reserve yield to retail users. Stablecoins that resemble collective investment schemes or deposit products trigger additional licensing requirements — creating a functional deterrent without a statutory ban.
The FCA announced on April 21, 2026, that it plans a payments rule overhaul to push stablecoins into mainstream finance. Stablecoin payments are listed as a 2026 priority. The regulatory sandbox remains open for stablecoin issuers testing products under supervised conditions.
The UK's position creates optionality. If the U.S. permits activity-based rewards under the CLARITY Act compromise, the UK can follow. If MiCA's categorical ban proves effective, the UK can adopt similar restrictions. The cost is regulatory uncertainty for firms operating during the consultation period.
The divergence creates measurable arbitrage. A USDC holder in Singapore faces different economics than one in New York, London, or Frankfurt — despite holding the same token backed by the same reserves.

The regulatory split incentivizes geographic structuring. DeFi protocols offering 4–8% APY on USDC and USDT through lending markets (Aave at $38.6 billion TVL, Morpho Blue at 3–12.63% APY) operate outside these frameworks entirely. A user in any jurisdiction can access DeFi yield — the prohibition applies only to issuer-level and platform-level payments in regulated environments.
This creates what the Oxford Law Blog described as a two-tier market: regulated on-ramps where stablecoins are payment instruments with zero yield, and unregulated DeFi markets where the same stablecoins function as interest-bearing instruments. The $28 trillion in quarterly stablecoin volume flows across both tiers.
The global regulatory response to stablecoin yield has converged on a single principle — issuers should not pay holders for holding — while diverging on implementation. The EU enacted a categorical ban. The U.S. wrote a ban with a loophole, then spent a year fighting over whether to close it. Hong Kong and the UAE matched Europe's rigor. Singapore imposed functional restrictions without statutory language. Japan and the UK deferred the question.
The result is a patchwork that achieves none of its stated objectives completely. Bank deposit bases are not protected when DeFi protocols offer 4–8% on the same stablecoins that issuers cannot remunerate. Consumer welfare is reduced when $14–16 billion in reserve income flows entirely to issuers rather than partially to holders. And regulatory clarity — the stated goal of every framework — is undermined by the divergence itself.
The CLARITY Act markup, expected in May 2026, will determine whether the United States resolves its internal contradictions. The answer will ripple across jurisdictions: if the U.S. permits activity-based rewards, pressure builds on the EU and Hong Kong to reconsider categorical bans. If the U.S. closes the loophole entirely, the current equilibrium — yield prohibition in regulated channels, yield abundance in DeFi — becomes the durable global norm.
