The $20.43 billion yield-bearing stablecoin sector slipped massively this week, according to stablewatch.io, as several synthetic and algorithmic stablecoins suffered heavy outflows and severe depegs. The turmoil centered around the yield-bearing stablecoins deUSD, XUSD, and USDX, all of which collapsed from their dollar pegs in a matter of days.
Massive Outflows Hit Leading Yield-Bearing Tokens
The latest fallout has rippled through decentralized finance (DeFi) markets, exposing the fragility of complex collateral systems underpinning yield-bearing tokens. The week’s losses were punctuated by cascading total value locked (TVL) declines across dozens of protocols.
Stablewatch.io data shows the biggest seven-day TVL drawdowns came from yUSD (-82.2%), mTBill (-59.5%), yUTY (-53.6%), and srUSD (-81.2%). Several smaller assets such as syUSD (-63.3%), sdUSD (-61.0%), and sUSDx (-88.2%) nearly evaporated.
Other major yield-bearing coins also posted steep declines — syrupUSDC (-10.6%), sDAI (-33.6%), and syrupUSDT (-8.8%) — pointing to how quickly confidence drained from the sector.

While a sea of yield-bearing stablecoins watched their liquidity trickle out, most managed to keep their stable composure — except for the trio of troublemakers: deUSD, XUSD, and USDX. Moreover, despite the red ink, a handful of assets managed to buck the trend. USCC (Superstate) and sGHO (Aave) both rose over 16% in TVL over the week, while gtUSDa (Gauntlet) skyrocketed 114.4%, marking one of the few bright spots amid the rout.
The Depeg Chain Reaction
The crisis began when Elixir’s deUSD, a synthetic stablecoin designed to generate yield through DeFi collateral, depegged from the U.S. dollar on Nov. 6, 2025. The collapse followed Stream Finance’s disclosure of a $93 million loss that crippled deUSD’s collateral reserves. Reports note that by the time Elixir processed redemptions for 80% of holders, the token’s price had plunged to roughly $0.015.
Stream Finance, which held 90% of deUSD’s remaining supply, reportedly did not close positions or repay exposure. That move was said to have forced Elixir to halt withdrawals and coordinate with partner protocols to mitigate losses. The depeg left thousands of users underwater and prompted renewed calls for stricter onchain transparency in DeFi collateral management.
Just hours after the deUSD collapse, XUSD — another synthetic stablecoin issued by Stream Finance — also lost its dollar peg, crashing to $0.20. Reports link the depeg to a $128 million exploit of the Balancer protocol, which drained key liquidity pools and triggered a chain reaction of liquidations.
The same exploit also destabilized USDX, the yield-bearing coin from Stables Labs, which plummeted to the $0.30–$0.38 range during panic-driven sell-offs. The liquidity crisis slashed USDX’s market cap by roughly 65% in one day and caused severe stress across integrated protocols such as Lista DAO and Pancakeswap.
Stables Labs has since announced a recovery initiative, including claim registration windows for affected holders based on onchain snapshots. But despite minor rebounds, USDX remains far below its $1 target, highlighting the systemic risk tied to algorithmic collateral design.
Current Standings
Across the yield-bearing stablecoin category, the week’s drawdowns totaled hundreds of millions in lost TVL. sUSDe (Ethena) fell 7% to $4.66 billion, while syrupUSDC (Maple) sank 10.6% to $1.18 billion. The ripple effect extended to secondary assets such as sDAI (Sky) and vyUSD (YieldFi), both down over 30% and 46%, respectively.
Average seven-day annual percentage yields (APYs) fluctuated sharply. For instance, yUSD’s APY dropped 4.7% to 8.73%, while coreUSDC (Upshift) spiked 8.2% to 11.99%. Meanwhile, mBASIS (Midas) saw an eye-catching 10.1% APY increase to 14.26%, indicating opportunistic risk-on behavior despite widespread losses.
Synthetic and Algorithmic Designs Under Fire
The string of depegs reignited long-standing skepticism toward algorithmic stablecoins. DeFi analysts note that while yield-bearing stablecoins attract liquidity with high APYs, their reliance on synthetic collateral and automated balancing systems exposes them to outsized tail risks.
To many observers, it could be the same systemic weaknesses that took down Terra’s UST, only in smaller doses. The parallels are hard to ignore: cascading liquidations, redemptions halted, and governance turmoil as protocols scrambled to patch holes in real time.
Despite the turmoil, a few protocols saw modest inflows. Superstate’s USCC gained 16.3% in TVL and Aave’s sGHO climbed 16%, which may be reflecting renewed investor appetite for projects with institutional backing or clearer collateral transparency.
Still, with overall market capitalization dipping 1.46% to $20.43 billion over the past 30 days, this past week proved that even yield-bearing stablecoins — long marketed as safer DeFi plays — are not immune to systemic risk.
Analysts expect ongoing volatility as DeFi teams behind these types of tokens work to restore confidence. Stablewatch.io’s dashboards continue to track inflows and APY adjustments, with several tokens now showing unusually high yield rates as they attempt to lure back liquidity providers.
For now, the narrative remains clear: the chase for yield in DeFi stablecoins carries risks that even a 20% APY can’t mask.
