CHAIN BREAKDOWN

Ethereum still dominates with $40.2B in sane stablecoin TVL across 1,591 pools above $100K, and TVL-weighted APY of 3.34%. Base and Arbitrum continue to host the bulk of L2 stablecoin yield activity at 1.43% and 2.13% TVL-weighted APY respectively, kept low by big Morpho V1 vaults that anchor the books at sub-5%.

Senate Banking Clears CLARITY Act 15-9, Bans Passive Stablecoin Yield but Spares Wrapped Vaults
On May 14 the Senate Banking Committee advanced the Digital Asset Market Clarity Act in a 15-9 vote, with Sens. Gallego and Alsobrooks crossing over to support. The Tillis-Alsobrooks compromise text bans passive stablecoin yield but preserves activity-based rewards and wrapped-vault structures.
Confirms the regulatory tailwind under Maple, Sky SUSDS, Sparklend, sUSDe, and Spark Savings - all of which deliver yield through tokenized wrappers rather than direct issuer interest, and all of which continue to absorb balances in this week's data.
Medium - Ben Fairchild
Maple Finance Crosses $4B Total Deposits With syrupUSDC at 63% of Book
Maple Finance's total deposits crossed $4B in 2026 with syrupUSDC representing 63% of the book. SYRUP listed on Revolut on April 30 with access to 70M+ EU and UK users, and Maple's bridge cleared $7B cumulative volume in late April.
Maps directly to Maple USDC at $3.42B / 4.82% and Maple USDT at $933M / 4.48% in this week's data, both at risk score 20-21. Materializes last week's high-confidence Maple Above $4B watch call.
Stablecoin Insider
Ethena sUSDe Yield Compresses Toward 3.5-4% as Rebalance Shifts Toward T-Bills
Ethena's sUSDe yield has compressed toward 3.5-4% after rebalancing away from perpetual funding into T-bills and institutional loans, with the 90-day trailing average still around 11.8% but the spot rate falling sharply. Reports indicate yields could dip below 2% in low-funding regimes.
Explains why our pool reads $1.81B at 4.24% with risk score 13. The mix shift makes sUSDe behave more like an RWA wrapper, putting it in the same regulatory bucket as Maple and Sky under the new CLARITY language.
OUTLOOK
Stablecoin yields are entering a wrapped-vault consolidation phase. CLARITY Act passage in committee with the passive-yield ban intact accelerates the migration that was already underway: balances are flowing into tokenized vaults (Maple syrupUSDC, Sky SUSDS, Sparklend USDS, Spark Savings, sUSDe) and out of direct issuer rewards. Aave V3 USDT's reset to 2.76% confirms the rsETH-era rate dispersion is closed and the new equilibrium for blue-chip lending is 2.5-3.5%, with Maple at 4.8% and sGHO at 5.4% as the only durable 5%+ low-risk yields. Expect Maple's growth to continue toward $5B and Sky SUSDS to stay pinned at 3.65% through May. Allocators looking for premium yield should rotate into Pendle PT/YT markets on USDC, PYUSD and DAI rather than chasing thin Aave residuals.
