Stablecoin Report #2: The Institutional Takeover
Total stablecoin market cap hits $320B as banks issue stablecoins, insurers settle in USDC, and 12 European banks build a euro stablecoin. The institutional takeover is here.
Market Snapshot
The stablecoin market has quietly entered uncharted territory. Total market capitalisation has climbed to a record ~$320B, up from ~$309B just two weeks ago. More importantly, the composition of that growth is shifting. USDC has overtaken USDT in adjusted transaction volume for the first time since 2019, processing ~$2.2T a year to date compared to USDT's ~$1.3T. That's not a blip. That's institutional capital voting with its feet.
January 2026 alone saw over $10T in stablecoin transaction volume, rivalling Visa's throughput. The gap between crypto native rails and traditional payment networks is closing faster than most expected.
| Metric | Edition 1 (3 Mar) | Edition 2 (16 Mar) |
|---|---|---|
| Total Stablecoin Market Cap | ~$309B | ~$320B |
| Monthly On-Chain Volume | $970B+ | $10T+ (Jan alone) |
| Yield-Bearing Stablecoin TVL | $22B+ | ~$22.7B |
| Tokenised Treasuries | $10B+ | $11B+ |
| Average DeFi Lending Rates | 4–5% | 4–7% (compressing) |
| USDC Adjusted Volume Share | N/A | 64% |
Key takeaway: The market isn't just growing. It's being restructured. Institutional, compliance-first capital is flowing toward regulated issuers and yield-bearing products, while raw USDT dominance continues to erode on a volume basis.
Dominance Breakdown
USDT and USDC still account for roughly 84% of total stablecoin supply by market cap. That headline number hasn't moved much. But underneath it, the dynamics are shifting rapidly.
Mizuho research published on March 13 confirmed what on-chain data had been suggesting for weeks: USDC now controls 64% of adjusted stablecoin transaction volume, processing roughly $1.26T in February alone versus USDT's $514B. The drivers are clear: MiCA compliance in Europe is steering activity toward transparent issuers, DeFi integrations favour USDC's deeper protocol relationships, and institutional treasuries are increasingly defaulting to Circle.
| Stablecoin | Market Cap | Share | Trend |
|---|---|---|---|
| USDT (Tether) | ~$184B | ~57% | Flat on cap, losing volume share |
| USDC (Circle) | ~$78B | ~24% | Record supply, 64% vol share |
| USDS (Sky/Maker) | ~$9.9B | ~3% | Sky Savings ATH $4B |
| USDe (Ethena) | ~$9.5B | ~3% | Down from $14.8B peak |
| PYUSD (PayPal) | ~$1B | <1% | Used in Aon insurance payment |
| GHO (Aave) | ~$527M | <1% | 15x growth, sGHO coming |
| DUSD (StandX) | ~$120M | <1% | Delta-neutral yield on BNB/Solana |
Circle's stock (CRCL) tells the institutional story better than any metric. Trading at ~$115–$118, up roughly 49% year to date, with Bernstein setting a price target of $190. Revenue hit $1.676B in FY2025. BlackRock manages the Circle Reserve Fund, BNY Mellon serves as custodian. This is no longer a crypto company. It's a financial infrastructure provider.
The Institutional Takeover
If Edition 1 was about the yield era taking shape, Edition 2 is about who showed up to claim it. The past two weeks have delivered a series of institutional moves that, taken together, represent a genuine inflection point for stablecoins as financial infrastructure.
SoFi x Mastercard: The First Bank-Issued Stablecoin Goes Live
On March 3, SoFi and Mastercard announced that SoFiUSD would be enabled as a settlement option across Mastercard's global payments network. This is the first stablecoin issued by a U.S. nationally chartered bank.
SoFiUSD isn't a crypto experiment bolted onto existing rails. It's a bank product running on crypto rails. Galileo, SoFi's fintech platform, will offer SoFiUSD settlement to its card clients. BitGo provides the stablecoin infrastructure. The message is clear: banks aren't waiting for regulatory clarity to ship products. They're building and letting regulators catch up.
Aon: Insurance Meets Stablecoins
On March 9, Aon became the first major global insurance broker to accept a stablecoin premium payment. They used USDC on Ethereum (via Coinbase) and PYUSD on Solana (via Paxos). This isn't a press release. It's a real payment for a real policy. When one of the world's largest insurance brokers is settling premiums in stablecoins, the "when will institutions adopt?" question has been answered.
Hong Kong: HSBC and Standard Chartered Set to Receive First Stablecoin Licences
Hong Kong's Monetary Authority received 36 applications under its new Stablecoins Ordinance (effective August 2025). HSBC and Standard Chartered are expected to be among the first approved, with licences potentially issued as early as March 24, 2026. Only three to four licences are expected in the initial batch.
Standard Chartered plans to launch an HKD-backed stablecoin through a joint venture with Animoca Brands and Hong Kong Telecom. The licensing requirements are rigorous: minimum HK$25 million in paid-up capital, high-quality liquid reserves, daily reserve disclosure, and redemption at par within one business day.
Qivalis: 12 European Banks Building a Euro Stablecoin
A consortium called Qivalis, comprising 12 major European banks including ING, UniCredit, BNP Paribas, BBVA, and CaixaBank, is building a MiCA-compliant euro stablecoin targeted for H2 2026. They're seeking Dutch Central Bank authorisation and already in talks with crypto exchanges for liquidity. This is not exploratory. This is a joint venture with a regulatory pathway and a launch date.
KAST: Stablecoin Payments at Scale
KAST raised $80M in Series A funding at a $600M valuation, co-led by QED Investors and Left Lane Capital. Founded by a former Circle Singapore CEO, KAST has over 1 million users, ~$5B in annualised transaction volume, and is targeting $100M in revenue run rate. The stablecoin payments layer is being built, and it's being funded aggressively.
What This Means
The pattern is unmistakable. Banks are issuing stablecoins (SoFi). Insurance companies are settling in them (Aon). European banks are building them together (Qivalis). Asia's largest banks are getting licenced (HSBC, Standard Chartered). And the infrastructure to scale payments is being funded at venture scale (KAST). The institutional takeover isn't coming. It's here.
Yield-Bearing Stablecoin Update
The yield-bearing segment continues to grow roughly 15x faster than the broader stablecoin market, according to Messari. Total TVL sits at approximately $22.7B. But the interesting story this edition isn't just growth; it's the competition for dominance within the category, and the growing pressure of yield compression.
| Token | Issuer | TVL/Supply | APY | Change |
|---|---|---|---|---|
| sUSDS | Sky (Maker) | ~$4.6B | ~4.5% | ATH, +60% in 30d |
| sUSDe | Ethena | ~$3.6B | ~4.3% | Yield compressing |
| sUSDf | Falcon | ~$2.5B | 7.5–10% | Stable |
| USYC | Circle (Hashnote) | ~$2.2B | ~4.5% | Overtook BUIDL |
| BUIDL | BlackRock | ~$2.24B | ~4.5% | Share: 46% to 18% |
| GHO (stkGHO) | Aave | ~$527M | ~8.4% | sGHO savings proposed |
| DUSD | StandX | ~$120M | 3–11% | Delta-neutral on BNB/Sol |
The Ethena Trajectory
Ethena's USDe deserves a closer look. Supply has fallen from its October 2025 peak of ~$14.8B to approximately $9.5B, while sUSDe yield has compressed from double digits to around 4.3%. The delta-neutral model that powered Ethena's explosive growth is now being tested by a lower funding rate environment. When perp funding rates compress, so does Ethena's yield advantage over simpler Treasury-backed alternatives.
That said, Spark's decision to allocate up to $1.1B to USDe/sUSDe, estimating ~27% APY in favourable conditions, suggests institutional confidence in the model's resilience. The question is whether Ethena can maintain competitive yields as more capital competes for the same funding rate arbitrage. If rates stay compressed, expect further supply contraction.
Yield Compression: The Broader Picture
It's not just Ethena. Yield compression is the defining trend across the entire yield-bearing stablecoin space. Sky's Savings Rate has been cut three times since 2025, dropping from 12.5% to 4.5%. DeFi lending rates on Aave have settled around 5–8% after peaking higher. Treasury-linked products are converging on 4–5%, which is essentially the risk-free rate with an on-chain wrapper.
The implication is clear: the easy yield era is maturing. Products that once offered eye-catching returns are normalising toward sustainable levels. For users, this means the differentiation between yield-bearing stablecoins is shifting from raw APY to factors like composability, collateral quality, redemption guarantees, and regulatory standing.
Other Notable Developments
Sky Savings hit an all-time high of $4B in TVL, a 60% increase in 30 days. Governance executed a vote reducing SKY staking emissions while continuing its buyback programme ($114.5M spent to remove 1.83B tokens).
Circle's USYC overtook BlackRock's BUIDL as the largest tokenised Treasury product (~$2.2B vs ~$2.24B). BUIDL's market share dropped from a peak of 46% to roughly 18% of the tokenised Treasury space.
USDsui launched on March 4 as Sui's native stablecoin via Stripe's Bridge platform, backed by U.S. Treasuries with a unique model: Treasury yields are used to buy and burn SUI tokens rather than paid directly to holders.
Flying Tulip, Andre Cronje's DeFi "super app" on Sonic, launched ftUSD, a yield-bearing stablecoin backed by delta-neutral LP positions. The project raised $225M from Brevan Howard Digital, DWF Labs, and Amber Group.
StandX DUSD (~$120M market cap) continues to grow on BNB Chain and Solana, offering 3–11% APY via a delta-neutral perpetual futures strategy. Integrated with Binance Wallet and PancakeSwap. Worth watching as a mid-cap yield-bearing entrant.
BUIDL: From Fund to Infrastructure
In Edition 1, we covered BlackRock's BUIDL listing on Uniswap via UniswapX as a landmark moment. Two weeks on, the broader story is becoming clearer. BUIDL isn't just a tokenised Treasury fund anymore. It's evolving into collateral infrastructure for institutional DeFi.
| Platform | Date | Use Case | Significance |
|---|---|---|---|
| Binance | Nov 2025 | Off-exchange collateral | Largest exchange adoption |
| Deribit | Jun 2025 | Margin collateral | Derivatives market access |
| Crypto.com | Jun 2025 | Cross-product collateral | Spot, margin, OTC |
| M0 Protocol | Dec 2025 | Stablecoin backing | RWA-backed stablecoin minting |
| Frax Finance | Late 2025 | frxUSD backing | DeFi-native collateral |
| Uniswap (UniswapX) | Feb 2026 | DeFi trading | First major TradFi fund on DeFi |
| Morpho Vaults | Q1 2026 | Lending collateral | Curated vault integration |
| Securitize/RLUSD | Sep 2025 | Redemption offramp | 24/7 BUIDL to RLUSD |
BUIDL is now live on nine chains, accepted as collateral on major centralised and decentralised platforms, and serving as backing for other stablecoins. The Uniswap integration remains restricted to qualified purchasers ($5M+ in assets) via Securitize compliance, with Wintermute among approved market makers. Access is still narrow, but the plumbing is being built for broader institutional participation.
The competitive pressure is real though. USYC's 198% market cap growth and overtaking of BUIDL shows that first-mover advantage in tokenised Treasuries doesn't guarantee dominance. The tokenised Treasury market has exceeded $11B, up 27% since the start of 2026, and is projected to surpass $14B by year end.
Regulatory Landscape
The OCC Fires a 370-Page Shot
On March 2, the Office of the Comptroller of the Currency published its proposed rulemaking to implement the GENIUS Act. At 370+ pages, this is the most detailed federal stablecoin regulatory framework ever proposed. The key provisions are significant:
Issuers must hold high-quality liquid assets (cash, Fed balances, short-dated Treasuries, qualifying repos, government money market funds) at fair value equal to or exceeding outstanding issuance at all times.
A rebuttable presumption that affiliate or third-party arrangements paying yield to stablecoin holders constitute prohibited interest. This is the OCC drawing a line in the yield debate.
Redemption at par on request, with a seven-day extension only permitted when redemptions exceed 10% of outstanding issuance in a rolling 24-hour period.
State-qualified issuers exceeding $10B in outstanding supply must transition to federal supervision within 360 days.
Minimum $5M capital for de novo issuers, plus 12 months of total expenses as an operational backstop.
The comment deadline is May 1, 2026. Meanwhile, the FDIC's chairman confirmed on March 11 that stablecoins will not be eligible for FDIC deposit insurance. They will rely instead on the full reserve mandate. The Fed is also developing its own capital and liquidity requirements but hasn't specified a timeline.
The CLARITY Act: Still Stalled
The CLARITY Act remains stuck in the Senate over stablecoin yield provisions. On March 5, the American Bankers Association formally rejected a White House-brokered compromise. Trump accused banks of "holding the bill hostage." Senator Alsobrooks is working with Senator Tillis on compromise language, and there's talk of passing the bill without the yield provision entirely.
The practical deadline is the November 2026 midterms. For the market, this means the regulatory framework for yield-bearing products remains undefined, which ironically hasn't slowed issuance or adoption at all.
Florida: First State-Level Stablecoin Bill
Florida Senate Bill 314 passed unanimously (37–0) on March 6. It's the first state-level stablecoin bill in the U.S., aligning with the federal GENIUS Act framework. Awaiting Governor DeSantis's signature, with an effective date of October 1, 2026. Expect other states to follow this template.
Europe: Banks Move Before Regulators Finish
The Qivalis consortium isn't waiting. They're building a MiCA-compliant euro stablecoin and seeking Dutch Central Bank authorisation for H2 2026. Meanwhile, the ECB issued a warning that stablecoin growth could weaken central bank monetary tools and shift deposits away from traditional banks. That's not a threat. That's an acknowledgement of reality.
IMF Weighs In
The IMF published two notable working papers. "Stablecoin Shocks" (March 6) found that stablecoin demand shocks cause persistent declines in short-term Treasury yields and USD depreciation. "From Par to Pressure" modelled the feedback loop between systemic stablecoin redemptions and financial market stability. The message: stablecoins are now big enough to be macro relevant.
Asia Pacific
Hong Kong is set to issue its first stablecoin licences (see The Institutional Takeover section). In South Korea, Hana Financial launched a USDC pilot on March 5 for tourist payments, partnering with Circle and Crypto.com, while also building toward a KRW-pegged stablecoin consortium. The Digital Asset Basic Act is expected to be fully implemented in 2026.
DeFi Lending and Stablecoin Rates
The broad trend from Edition 1 continues: rates are compressing as more capital enters DeFi lending markets. Aave dominates with roughly 65%+ of DeFi lending market share and ~$26.5B in TVL. But the competitive landscape is evolving.
| Protocol | USDC Supply APY | TVL | Market Share | Notes |
|---|---|---|---|---|
| Aave V3 | ~7.7% avg | ~$26.5B | ~65%+ | V4 audits ongoing |
| Morpho | 4–7% | $10B+ | Growing | Tighter spreads via curators |
| Compound V3 | <5% | ~$2.1B | Declining | Conservative, never exploited |
| Spark | ~4.5% (SSR) | Growing | Growing | $1.1B Ethena allocation |
| Fluid | Variable | Growing | Emerging | Lending + DEX hybrid |
Aave Governance Crisis
The biggest DeFi lending story this cycle wasn't about rates. It was about governance. On March 3, the Aave Chan Initiative (ACI), which drove 61% of Aave governance actions over three years, announced it was shutting down. The dispute centred on the "Aave Will Win" proposal requesting approximately $51M plus 75,000 AAVE tokens. The Temp Check passed narrowly at 52.58% for versus 42% against.
For Aave V4, which is still in development with audits ongoing and a $1.5M bug bounty proposal filed on March 5, this governance fracture introduces uncertainty. The planned Hub-and-Spoke architecture, ERC-4626 share accounting, and GHO savings product (sGHO at ~8.4% APY) all depend on functional governance. Worth watching closely.
Emerging Trend: Stablecoin as a Service
A quiet but significant shift is underway. The infrastructure to issue and manage stablecoins is being productised. You no longer need to build from scratch to launch a stablecoin. You need the right partners.
The SaaS Stack
BitGo is providing full stablecoin infrastructure for SoFiUSD, handling custody, minting, and redemption as a service.
Stripe's Bridge platform (acquired 2024) powered USDsui's launch on Sui via its Open Issuance platform. Twelve DeFi protocols integrated at launch.
Circle is building Arc, a Layer 1 blockchain purpose-built for stablecoin finance, with USDC as the native gas token and sub-second finality. Testnet has been live since October 2025, with mainnet expected in 2026.
AI Agents Meet Stablecoins
Circle's Arc blockchain is explicitly designed for autonomous AI agent commerce, enabling micropayments with USDC. Bernstein identifies this as a major growth catalyst for Circle. The vision: millions of AI agents settling transactions in stablecoins without human intervention. Circle is partnering with Anthropic's Claude Agent SDK for AI-powered developer tools on Arc.
What This Means for the Market
Stablecoin issuance is being democratised. The same way Stripe made it easy to accept payments online, platforms like BitGo, Bridge, and Circle Arc are making it easy to issue, manage, and settle stablecoins. The implication is more issuers, more competition, and ultimately more specialisation. Expect to see sector-specific stablecoins (insurance, real estate, trade finance) proliferate through 2026 and beyond.

The Alto Perspective
Two weeks ago, we wrote about the yield era. This edition makes it clear that the yield era has attracted exactly the participants you'd expect: banks, insurers, asset managers, and sovereign regulators.
The stablecoin market is no longer a crypto sideshow. At $320B in market cap, $10T+ in monthly volume, and with the world's largest banks actively building issuance products, stablecoins have become the connective tissue between traditional finance and on-chain economies.
What's particularly notable is the speed. SoFi didn't announce a stablecoin research initiative. They shipped a product on Mastercard's network. Aon didn't publish a white paper on stablecoin settlement. They paid an insurance premium in USDC. Twelve European banks aren't studying the feasibility of a euro stablecoin. They're building one with a target launch date. HSBC and Standard Chartered aren't exploring blockchain experiments. They're days away from receiving stablecoin licences in Hong Kong.
Meanwhile, the OCC has dropped a 370-page proposed rulemaking that signals exactly how seriously federal regulators are taking stablecoin oversight. The yield debate between banks and crypto firms remains unresolved, but the infrastructure is being built regardless. Yield compression across the board is forcing a maturation of the space, shifting competition from raw APY toward composability, regulatory standing, and institutional trust.
For protocols and builders in the Alto ecosystem, the implications are direct. The capital flowing into stablecoins is increasingly institutional, compliance-conscious, and yield-seeking. Protocols that can support tokenised RWAs, offer transparent yield generation, and integrate with regulated stablecoin infrastructure will capture the next wave of flows.
The question is no longer whether institutions will adopt stablecoins. It's whether crypto-native protocols can adapt fast enough to serve them.
