"Stablecoins have found limited commercial use, such as for firms' payments within global value chains. Instead, they have primarily served for on-chain trading within the crypto ecosystem." — Pablo Hernández de Cos, General Manager, Bank for International Settlements
The stablecoin market hit a record $322 billion in mid-April 2026, yet the sector's governing infrastructure remains fragmented, slow-moving, and jurisdictionally inconsistent. On April 20, BIS General Manager Pablo Hernández de Cos delivered a speech at a Bank of Japan seminar in Tokyo that laid bare the central tension: stablecoins moved approximately $35 trillion in 2025, but only $390 billion — roughly 1.1% — reflected actual payment activity, according to McKinsey. The rest was trading, liquidity shuffling, and automated blockchain activity.
The speech marked a modest tonal shift from the BIS, which had previously characterized stablecoins as "unsound money." Hernández de Cos acknowledged that specific mechanisms — deposit insurance-type arrangements, central bank liquidity backstops, and redemption-at-par regulation — could mitigate structural risks. But the core message was a warning: without coordinated global rulemaking, regulatory arbitrage will drive issuers to lighter-touch jurisdictions, fragmenting a market that already operates more like exchange-traded funds than money.
Simultaneously, the U.S. CLARITY Act remains stalled in the Senate over a dispute about whether stablecoin issuers can retain yield on reserve assets. The EU's MiCA regime is mid-rollout. The Bank of England is consulting on a systemic stablecoin framework that would extend central bank liquidity to issuers. Japan has restricted issuance to licensed banks and trust companies. The result: six major regulatory models, none interoperable, governing a market dominated by two U.S.-linked issuers holding 82% combined market share.
The stablecoin market reached an all-time high of $322 billion in April 2026, according to DefiLlama, after absorbing $2.54 billion in net inflows in a single week ending April 16. The market has expanded roughly 7% year-to-date.
Tether's USDT dominates with $188 billion in circulation and a 57.96% market share — though that figure has slipped from 60.46% earlier in 2026, a 2.5 percentage point decline. Circle's USDC holds $78.6 billion (approximately 24.4% share), having grown 73% through 2025 and continuing to gain ground in 2026. Together, the two account for roughly 82% of all stablecoin supply, down from 88% in early 2025.
The remaining 18% is increasingly contested. Sky Dollar (USDS) sits third at $8.6 billion. Ethena's USDe holds $5.8 billion. Behind them, 14 MiCA-authorized issuers across seven EU member states now operate approximately 20 compliant stablecoins, though none has reached meaningful scale.
Ethereum hosts approximately 60% of global stablecoin supply (~$170 billion). TRON holds roughly $87 billion, primarily USDT for peer-to-peer transfers in emerging markets. Solana's share is smaller but growing.
The April 20 speech at the Bank of Japan was notable for what it conceded. The BIS, which has historically positioned itself as a stablecoin skeptic, acknowledged for the first time that deposit insurance-type arrangements, central bank liquidity backstops, and regulated redemption-at-par mechanisms could address structural weaknesses in stablecoin design.
However, the concession came with conditions. Hernández de Cos framed stablecoins as instruments that "currently operate more like exchange-traded funds than like money," noting that their market cap of $315 billion (at the time of the speech) was dwarfed by roughly $8 trillion in U.S. bank deposits alone.
The core warning was about fragmentation. Without coordinated global rulemaking, the BIS argued, firms would exploit divergent regulatory regimes — a dynamic Hernández de Cos called "harmful regulatory arbitrage." He noted that stablecoin structure can resemble securities more than cash, with redemption frictions pushing prices away from the intended $1 peg during stress events.
On monetary policy, the speech flagged that wide stablecoin adoption — particularly dollar-denominated stablecoins in non-U.S. jurisdictions — could constrain local central banks' ability to conduct monetary policy and accelerate dollarization. This concern is particularly acute for emerging markets where stablecoin demand is strongest.
The BIS's preferred alternative remains clear: tokenized central bank money and commercial bank deposits operating on a shared infrastructure, as currently being tested through Project Agorá.
As of April 2026, at least six major jurisdictions have distinct stablecoin frameworks in various stages of implementation:
United States: The CLARITY Act (Digital Asset Market Clarity Act) passed the House in 2025 and is now before the Senate Banking Committee, chaired by Tim Scott. A compromise on stablecoin yield was reached by Senators Thom Tillis and Angela Alsobrooks, but the bill remains stalled over DeFi oversight provisions and ethics requirements. Subcommittee chair Cynthia Lummis indicated a hearing could occur in the second half of April 2026. Until the bill passes, stablecoin issuers operate under a patchwork of state money-transmitter licenses.
European Union: MiCA's Phase 2 became operational in January 2026, classifying stablecoins as either e-money tokens (EMTs) or asset-referenced tokens (ARTs), each requiring 100% reserve backing and monthly audits. By early 2026, 14 issuers held MiCA authorization across seven member states. Existing crypto-asset service providers operating under national law must obtain MiCA authorization by July 1, 2026 or cease operations.
United Kingdom: The Bank of England published a consultation paper in November 2025 proposing a regulatory regime for sterling-denominated systemic stablecoins, with responses due by February 2026. The regime would permit issuers to hold up to 60% of backing in short-term UK government debt, with 40% in unremunerated Bank of England accounts. The Bank is considering extending central bank liquidity to systemic stablecoin issuers during periods of stress — the most accommodative central bank posture toward stablecoins proposed by any major jurisdiction. Final rules are expected by year-end 2026.
Japan: The FSA restricts stablecoin issuance to licensed banks, registered fund transfer service providers, and trust companies, under Payment Services Act amendments effective since June 2023. Japan's three largest banks are developing stablecoin issuance capabilities, with FSA support confirmed in November 2025.
Hong Kong: HSBC and Standard Chartered received the first stablecoin licenses under the HKMA's framework in April 2026.
Singapore, UAE, and others: Additional frameworks exist in various stages of development, each with distinct licensing, reserve, and redemption requirements.
The fundamental problem, as identified by the BIS, is that none of these regimes are interoperable. A stablecoin compliant under MiCA may not satisfy Bank of England requirements. A U.S.-licensed issuer faces uncertain status in Japan. The result is a compliance maze that favors large, well-resourced issuers — primarily Tether and Circle — while creating barriers for smaller entrants and cross-border payment use cases.
The fastest-growing segment of the stablecoin market is yield-bearing instruments. According to industry data, the yield-bearing stablecoin market reached $22.7 billion by March 2026 — growing approximately 15 times faster than the overall stablecoin sector over the preceding six months.
This category expanded 22% in Q1 2026 alone and contributed more than half of the sector's net supply growth, adding roughly $4.3 billion in market capitalization during the quarter.
Key yield-bearing stablecoins include:
The growth of yield-bearing stablecoins is directly relevant to the CLARITY Act deadlock. The central legislative dispute is whether stablecoin issuers should be permitted to retain interest earned on reserve assets or pass returns to holders. Yield-bearing stablecoins resolve this question by design — they pass yield through — which is precisely why traditional banking interests have resisted their regulatory accommodation.
McKinsey's analysis of 2025 stablecoin activity provides the most granular decomposition of actual use. Of the approximately $35 trillion in total stablecoin transaction volume, only $390 billion — about 1.1% — represented actual payment flows.
That $390 billion breaks down as follows, according to McKinsey:
The remaining 98.9% of volume consisted of trading, liquidity provision, automated market maker activity, and intra-protocol fund movements — none of which represent economic payments in the traditional sense.
For context, the $390 billion in actual stablecoin payments represents approximately 0.02% of global payment system volume. This figure, cited by Hernández de Cos in his Tokyo speech, underpins the BIS position that stablecoins have not achieved meaningful payment adoption despite seven years of growth.
However, the $390 billion figure has grown substantially from prior years, and the B2B segment ($226 billion) suggests real enterprise traction. The question is whether regulatory clarity — or the lack of it — will accelerate or constrain this trajectory.
The BIS's preferred path forward is not stablecoin regulation but stablecoin displacement. Project Agorá, a collaboration between the BIS Innovation Hub and seven central banks — the Bank of France (representing the Eurosystem), Bank of Japan, Bank of Korea, Bank of Mexico, Swiss National Bank, Bank of England, and the Federal Reserve Bank of New York — is exploring tokenized central bank money and commercial bank deposits for cross-border payments.
Over 40 private financial institutions have joined the initiative. The project moved from design to prototype-building phase, with a lessons-learned report expected in H1 2026 that will analyze legal and regulatory gaps across all seven jurisdictions.
The BIS has been clear that Agorá is an experiment, not a product roadmap. But the institutional weight behind it — seven of the world's most significant central banks, plus the private banking sector — signals that the establishment preference is for tokenized bank deposits settling against central bank reserves, not privately issued stablecoins operating outside the banking system.
The tension between these two models — private stablecoins governed by fragmented national rules versus tokenized deposits governed by central bank infrastructure — will likely define the next phase of digital money competition.
The stablecoin market's $322 billion headline figure masks a sector still searching for its primary function. Ninety-nine percent of transaction volume is trading infrastructure, not payments. The 1% that is payments — $390 billion — is meaningful but small relative to global payment flows.
The BIS speech in Tokyo was not a policy prescription. It was a signal. Central banks are prepared to accommodate stablecoins within regulated frameworks — but only if global coordination prevents issuers from shopping for the lightest regime. Absent that coordination, the BIS made clear, the risks to monetary policy, financial stability, and consumer protection multiply.
The irony is that while regulators debate frameworks, the market has already decided what stablecoins are: predominantly dollar-denominated trading infrastructure, not a global payments layer. Whether regulation can reshape that reality — or merely ratify it — remains the open question.
