Stablecoin Weekly: Distribution Doesn't Wait

Three days after the week that renegotiated how stablecoin issuers connect to the dollar, the government that had been doing the renegotiating went home. May 25 was Memorial Day. The Senate was in recess, Kevin Warsh delivered no policy speech in his first full week as Fed chair, CLARITY did not reach the floor, and the SEC shelved the tokenized-stock "innovation exemption" it had spent a month signaling, after the major equity exchanges pushed back. For two straight weeks the policy calendar had set the agenda. This week it went quiet, and the distribution layer did not wait for it. Inside the same five business days, a national bank put a stablecoin in front of 15M retail customers, a 60M-user payments app began rolling USDC to its base, a global payout network wired USDC settlement into more than 190 countries, a federally chartered crypto bank issued a GENIUS-ready dollar, and the first blockchain-native firm was registered by the SEC to clear and settle U.S. securities on-chain. The build-out moved down the stack, from who connects to the dollar to who reaches the user. And it moved into a market that was, for the first time in weeks, shrinking.

• The distribution layer shipped to tens of millions of users in a single week. SoFi Bank launched SoFiUSD, the first stablecoin issued by a U.S. national bank to live inside a consumer banking app, to roughly 15M members on Ethereum and Solana. Block began a phased rollout of USDC to Cash App's nearly 60M users. Circle connected USDC settlement to Nium's payout network across more than 190 countries and 100 currencies. Falcon Finance and Anchorage Digital Bank launched fUSD, a GENIUS-ready dollar issued by a federally chartered crypto bank. None of it required a new rule to ship.
• Washington stepped back, and the SEC stepped backward. Memorial Day put the Senate in recess; Warsh gave no policy speech and no master-account or stablecoin signal in his first full week; CLARITY did not move and its combined text with the Senate Agriculture bill remained unwritten. The one reversal was the SEC shelving its tokenized-stock innovation exemption after NYSE, Nasdaq, and Cboe flagged market-structure risk, with no new timeline. The equities-side analogue to the Fed's settlement-access plan stalled.
• Supply rolled over off its all-time high, and on-chain yield fell below cash. Aggregate stablecoin supply eased back from the mid-May record near $323.3B, the first sustained weekly contraction after the multi-week run, led by USDT redemptions on the order of $2B. The 3-month Treasury bill (near 3.60%) now sits above Aave's USDC supply rate (near 3.24%) and roughly level with the Sky Savings Rate (near 3.60%); the only above-cash, peg-stable rate left in the savings layer is Aave's administered 4.25% sGHO.
• The RWA leader lost its founder, and the euro issuer tier stayed broken. Ondo Finance announced the unexpected death of founder Nathan Allman on May 26; president Ian De Bode was named CEO. StablR's euro stablecoin EURR entered a second week roughly 45% below peg, with mint and redeem frozen and the issuer's own admission that the tokens are no longer fully backed, while a $5.4M drain of the Gravity Bridge (mostly USDC and USDT) extended the year's key-management failure pattern.

Aggregate supply contracted for the first time since the all-time-high run began. The level is still historically high, but the direction turned, and this time the largest issuer led the drain rather than a challenger leading the gain.

• Total stablecoin market cap eased to roughly $318B to $320B as of the May 30-May 31 turn, down from the mid-May high near $323.3B. Trackers diverge by several billion (DefiLlama reads several billion below CoinMarketCap because it truncates the long tail), and issuer-source aggregation lags, so treat the level as a range and the direction, a first sustained contraction, as the reliable signal.
• USDT is the drain. It read near $187B with share around 58.6%, off roughly $2B on the week, the single largest absolute outflow and the engine of the aggregate decline.
• USDC softened again to roughly $76B, a continuation of the multi-week drift rather than a new break.
• USDe (Ethena) held near $4.5B, essentially flat, an outperformance in a down week even as its yield compressed (below).
• USD1 (World Liberty Financial) gave back roughly 3% to about $4.6B after weeks as the top five's strongest gainer.
• RLUSD (Ripple) rose toward $1.73B, supported by a fresh attestation dated May 28 showing about $1.83B of reserves against circulating supply.
• USDS (Sky) reads between roughly $8.8B (DefiLlama) and $11B (CoinGecko), a genuine ~$2B divergence that reflects mid-flight DAI-to-USDS migration accounting rather than a real move; DAI shows the mirror-image gap. Do not anchor to a single USDS figure without naming the source.
• PYUSD eased to about $3.0B; USDG held near $2.56B.
• Tokenized U.S. Treasuries plateaued near $14.7B to $15.2B, flat to slightly down on the month, with Ethereum still hosting roughly half. The category stopped growing at the same moment the dollar tokens above it did.

The leaderboard reshuffled under a flat top line.

• USYC (Circle) near $2.90B, displayed yield around 3.2%, back in front of BUIDL.
• BUIDL (BlackRock / Securitize) near $2.40B (about 3.4%), slipping just below USYC after holding the second slot.
• USDY (Ondo) near $2.14B (about 3.55%), flat.
• iBENJI (Franklin Templeton institutional) near $1.59B; the retail BENJI asset near $816M, up on the month.
• WTGXX about $881M, JTRSY about $871M (down), USTB about $749M (down, post-Invesco handoff), OUSG (Ondo) about $573M inside its unresolved on-chain-versus-total methodology band, and CUMIU about $547M at the category's highest displayed yield near 3.73%. Displayed yields across the largest products drifted into a 3.1%-to-3.7% band as the front end eased.

The anchor barely moved, and that is the story. Effective fed funds held at 3.62%, and the 3-month Treasury bill eased to about 3.60%, down a few basis points into month-end. That number now sits above most of the on-chain dollar stack beneath it. For the first time in this cycle there is no structural premium to cash in the base or pooled-lending layer: a Treasury bill out-yields Aave USDC. Every rate above roughly 3.6% in the sections below is now compensation for credit, leverage, duration, or an administered subsidy, not a free on-chain spread over the risk-free rate.

The savings layer drifted lower in lockstep with bills. The Sky Savings Rate (sUSDS) eased to about 3.60%, and Aave's Ethereum USDC supply rate sat near 3.24% (with USDT near 2.78%), both at or below the bill. No new Sky or Spark spell executed in the window. The exception, and the only clean above-cash savings rate left, is Aave's sGHO at a fixed 4.25%, set deliberately 50 basis points above sUSDS. That rate is administered, not earned: Aave governance is subsidizing it to bootstrap deposits into its native dollar, and a vote can cut it. The GHO peg held at $1.00. Aave's in-window governance was routine cap housekeeping that nonetheless carried a signal: Risk Stewards raised USDtb and USDT supply and borrow caps on May 25 and May 26 to relieve saturated, BTC-collateralized stablecoin-carry borrow demand, and began winding down WETH and tokenized-gold collateral on the new Plasma instance. The carry trade is the marginal borrower on Aave right now. Morpho's curated USDC vaults remained the richest mainstream venue (Steakhouse USDC near 4.6%) on roughly $11.8B to $12B of deposits, but that premium is the curator's market-selection and liquidity risk, not a base rate.

The carry layer compressed toward the savings layer as perpetual funding cooled, and the most important number in it is the one most often misquoted. Ethena's sUSDe yields about 3.9% net of fees, the figure a fresh deposit actually realizes, not the roughly 9% gross trailing figure that still appears on aggregator dashboards. The wedge is Ethena's fee switch, which routes a share of protocol earnings to sENA and the reserve fund before the residual reaches sUSDe holders. Underwriting sUSDe at the headline overstates realizable yield by roughly five percentage points. USDe supply fell about 13% over the trailing month as the funding that powers the basis trade softened, and capital is voting on the compressed net. Maple's syrupUSDC and syrupUSDT printed about 4.6% to 4.7%, still below the platform's 6%-to-10% target band, real loan interest rather than incentive; the Maple Borrower Hub that launched the prior week is an operations upgrade, not a yield event, and the legacy dashboard sunsets June 30. Pendle TVL held near $1.5B, flat, with the Ethena complex still its dominant base. On MegaETH, the second monthly MEGA buyback that the USDe/USDm loop's flywheel depends on had not been confirmed by the end of the window, with a token unlock due June 23, leaving the reflexive bid an open question rather than a settled mechanic.

The five business days from May 26 to May 30 produced the densest run of distribution news of the cycle, and it shared a single property: none of it waited on a regulator.

Block began a phased rollout of USDC to Cash App's nearly 60M users on May 27, starting at a quarter of the base and widening across the week, with self-custody transfers to external wallets on Solana, Ethereum, Polygon, and Arbitrum. The same day, SoFi Bank launched SoFiUSD, the first stablecoin issued by a U.S. national bank to live inside a consumer banking app, redeemable one-to-one through the bank and available to roughly 15M members. Also the same day, Circle connected USDC settlement to Nium's cross-border payout network, extending one-to-one dollar settlement into more than 190 countries and 100 local currencies through the Circle Payments Network. Two of those three are consumer onboarding at a scale stablecoins have not previously reached inside regulated U.S. financial apps; the third is the last-mile payout reach that turns a settlement token into a usable cross-border rail.

Underneath the consumer layer, the institutional plumbing advanced in the same week. Falcon Finance and Anchorage Digital Bank launched fUSD on May 27, a GENIUS-ready dollar issued by the only federally chartered crypto bank in the country, with reserves under OCC supervision and attested monthly, and a roughly 3% reward shared with institutional holders. On May 28, the SEC registered Paxos Securities Settlement Company as a clearing agency, the first blockchain-native firm cleared to settle U.S. securities on-chain. The registration is temporary, but it is structural: it puts a regulated central securities depository on a blockchain rail for the first time.

Read together, the week answered a question the prior two issues had only framed. The contest over stablecoin economics has moved down the stack twice in three weeks: from who captures the reserve float (the issuer-versus-venue fight), to how the float connects to the dollar payment system (the Fed Payment Account), to who controls distribution to the end user. This week the last question started to resolve, and it resolved toward incumbents with existing distribution: a national bank, a 60M-user fintech, a global payout network, a federally chartered custody bank, and a regulated on-chain clearing agency. The common thread is that the GENIUS framework is now real enough that scaling distribution no longer waits for each incremental rulemaking step. The issuers and distributors treated the regulatory question as settled enough to ship, in the same week the regulators themselves were not in the building.

While distribution accelerated, the policy machine that had driven the prior fortnight went quiet, and in one place it reversed.

The Senate was in Memorial Day recess. Kevin Warsh, sworn in May 22, delivered no policy speech in his first full week and gave no public signal on stablecoins, master accounts, or the Payment Account proposal; the only Fed remarks in the window were on monetary policy and AI. His first FOMC is June 16-17. The Payment Account proposal itself did not move: its comment clock is running toward a late-July close (July 27), and no issuer or bank-trade response had surfaced.

CLARITY did not reach the floor, its combined text with the Senate Agriculture Committee bill remained unwritten, and the conflict-of-interest provisions stayed the unresolved blocker against an August-recess clock. The House offered the week's clearest forward signal: Financial Services Chair French Hill framed tokenization as the committee's next priority and, notably, as "an exercise in changing systems," not changing the law, pointing toward exemptive relief and existing authorities rather than new statute.

The reversal was at the SEC. The tokenized-stock "innovation exemption" that last week's watchlist was tracking, the equities-side analogue to the Fed's cash-settlement access, was shelved with no new timeline after NYSE, Nasdaq, and Cboe leadership flagged that its third-party-token provision (digital representations of listed shares issued without the company's consent, trading in a 12-to-36-month sandbox outside National Market System rules) would carve a parallel venue around the rules every other equity market follows. Robinhood, Coinbase, Ondo, and Securitize had all built roadmaps around it. The on-ramp for tokenized equities, the fastest-growing RWA category, just got routed back toward traditional market-structure plumbing.

The one live policy fight was over the charters that make the week's bank-issued dollars possible. Senator Warren gave the OCC until June 1 to hand over records on the nine national trust charters it has granted to crypto firms, including Ripple, Coinbase, and Paxos, calling them illegal under the National Bank Act; the Digital Chamber publicly rebutted her on May 27. The same charter path that lets Anchorage issue fUSD, and that underpins much of the non-bank issuer pipeline, is now contested in writing.

The week's hardest news was a death. Ondo Finance announced on May 26 that founder Nathan Allman had died unexpectedly; the company named president Ian De Bode, who has run strategy and operations since 2024, as chief executive. Allman built Ondo into the dominant tokenized-real-world-asset franchise, roughly $3.8B in total value and more than 70% of the tokenized-equity market, after starting the firm in 2021 out of Goldman's digital-assets group.

The institutional read is narrow and not about sentiment. Ondo carries a set of open items into a leadership transition: an unresolved methodology gap on OUSG's on-chain-versus-total size, a tokenized-stock business whose regulatory on-ramp just stalled at the SEC, and a confidential securities registration in flight. De Bode inherits all of it with the founder's continuity premium gone. For counterparties underwriting Ondo exposure, key-person and roadmap-continuity risk moved from theoretical to live this week, and the catalyst calendar now runs through a new principal.

Elsewhere on the issuer tier the news was incremental and confirming. Ripple's May 28 RLUSD attestation showed reserves of about $1.83B against roughly $1.73B circulating, the cushion and the cadence both intact as the token approaches $2B. Tether published its monthly attestation for USAT, its U.S.-focused dollar, at about $141M, growing fast in percentage terms but still immaterial in absolute size next to USDC, PYUSD, and RLUSD. The reserve-vehicle race that defined early May (BlackRock's BRSRV and BSTBL, JPMorgan's JLTXX) produced no new approval.

Europe spent the week arguing with its own framework rather than shipping product. UniCredit's risk-committee head warned on May 28 that MiCA pushes stablecoin issuers into the banking perimeter while denying them deposit-insurance backstops, leaving the EU less able to contain a stablecoin or crypto-bank failure than U.S. regulators proved in 2023, when Circle's USDC reserves were briefly caught at Silicon Valley Bank. The European Commission's MiCA review consultation, open through August, put the two questions that matter most for dollar issuers formally back in play: whether to keep the de-facto ban on non-EU stablecoins, and whether to keep prohibiting interest on e-money tokens. The Bank of England's promised June draft of systemic-stablecoin rules had not landed by month-end, leaving the 40%-central-bank-deposit backing requirement and the holding caps unresolved going into publication.

The more structural international item came from the issuer side. Tether and the government of Georgia agreed on May 25 to launch GELT, an official lari-denominated stablecoin under a national framework explicitly designed for GENIUS-Act compatibility. A sovereign putting its own currency on a private issuer's rails, under a U.S.-aligned framework rather than a domestic central-bank digital currency, is the template worth watching: it is the emerging-market mirror image of the bank-issued dollars launching in the U.S.

The euro depeg that opened last week did not close. StablR froze minting and redemption for EURR and USDR on May 26 and asked exchanges to halt trading, after the prior week's compromise of a one-of-three mint multisig produced roughly $13.5M of unauthorized tokens. USDR clawed most of the way back to par, but EURR spent the week roughly 45% below peg, and the issuer admitted in writing that circulating supply is no longer fully backed at one-to-one, a direct MiCA breach it said it would report to Malta's MFSA, its home regulator, under MiCA and DORA. By the end of the window there was still no remediation plan, no confirmation that reserves cover the unauthorized mints, and no disclosure that the compromised multisig had been rotated. The first issuer-tier failure of the cycle is now a multi-week event at a MiCA-authorized issuer, and the partial recovery that did happen came from a downstream payments app freezing funds, not from the issuer's own controls.

The week's largest stablecoin-denominated loss came from the same attack class. The Gravity Bridge was drained of about $5.4M on May 30, roughly $4.3M of it USDC and $434K USDT, in what analysts attributed to a compromised validator signing key rather than a contract bug. It rhymes with StablR, and with the Kelp and Resolv incidents earlier in the year: 2026's losses are increasingly operational and key-management failures, not code exploits, even as the absolute monthly total fell sharply from April's spike to roughly $68M. For stablecoin underwriting specifically, the lesson compounds: mint-authority key custody and multisig composition are now first-order diligence items, not afterthoughts.

One legal catalyst sits just past the window. The roughly $71M Aave frozen-ETH proceeding, the test of whether a DeFi protocol can recover sanctioned-linked ETH ahead of terrorism-judgment creditors, has its review hearing on June 5; supplemental briefs were filed May 22 and no ruling came in the window. It is the highest-leverage near-term event on the legal calendar.

Three weeks ago the question was who captures the reserve float. Two weeks ago it was how that float connects to the dollar payment system. This week the question became who controls distribution to the end user, and the answer started to resolve toward whoever already owns the user.

The institutions that shipped this week were not crypto-native challengers. They were a national bank, a 60M-user payments app, a global payout network, a federally chartered custody bank, and a regulated clearing agency. That is the tell. The reserve float and the settlement rail are commoditizing; the scarce asset is distribution, and distribution accrues to incumbents with existing user bases, charters, and corridors. For ArkenYield's underwriting frame, the implication carries forward cleanly: a stablecoin's credit and economic profile now depends on its distribution stack, which app, which bank, which payout network, and on what terms, at least as much as on its reserve composition. Underwrite the distribution contract.

The counterpoint is the discipline. All of this shipped into a market that was, for the first time in weeks, contracting, with aggregate supply rolling over off its record and on-chain yield falling below the Treasury bill. Distribution is scaling, but it is scaling a share of a flat-to-shrinking pie, not riding a yield-driven inflow. The growth is a land-grab, not a carry trade. And the StablR depeg, unresolved into its second week at a regulated issuer, is the reminder that the operational-security floor has not risen to meet the distribution ambition. The political question became operational two weeks ago. This week it became commercial. The diligence now lives where the users are, and on whether the issuer reaching them can keep its own keys.
