Ethena’s synthetic dollar USDe is in full retreat. The token’s market cap has slid from about $14.7 billion on October 9 to roughly $6.4 billion this week, a drawdown of around $8.3 billion, according to a new note from 10x Research and live data from CoinMarketCap and DeFiLlama. The move tracks a broader shift into deleveraging after the October crash and raises fresh questions about how much risk DeFi can stack on a reflexive yield engine.
USDe still trades near its $1 target. CoinMarketCap shows the token around $0.9987 with a circulating supply of roughly 6.38 billion, for a market cap of $6.38 billion on December 23. DeFiLlama and CoinGecko report similar figures. So this is not a persistent depeg. It is a violent contraction in size.
Ethena’s governance token ENA trades under similar pressure. ENA changed hands near $0.195 on Monday, down about 8.6% over 24 hours and roughly 12% over the past week, with a market cap around $1.55 billion, per CoinGecko. The drawdown leaves ENA more than 85% below its April 2024 peak.
From peak growth to forced unwind in ten weeks
USDe’s supply expansion peaked just before the crash. Ethena’s own risk committee reported that USDe grew to roughly $14.3 billion by late September, and CoinGecko and The Defiant show a market cap above $14.6 billion on October 9.
That changed on October 10. A tariff headline from the Trump administration triggered the biggest liquidation event in crypto history, wiping out around $19 billion in margin positions and slashing open interest by roughly $65 billion, according to Coinglass data cited by Cointelegraph. USDe’s cap dropped by about $2 billion in the October 10–11 window as traders rushed to redeem.
An analysis by Blockworks Advisory on Ethena’s governance forum tallied roughly $1.9 billion of USDe redemptions processed between October 10 and 11, more than 13% of the then $14.6 billion supply, and noted that Ethena did not tap its reserve fund or build a backlog of withdrawals. That flow started the bleed. It did not stop there.
The Defiant tracked another $3 billion drop in USDe’s cap over the rest of October, to about $9.2 billion by month end. A November 3 update from Ethena’s reserve fund subcommittee then flagged a move from $14.3 billion to $9.61 billion over roughly a month of stress. By early December, the same committee put supply near $7.05 billion, with “continued negative market conditions” and ongoing redemptions. CoinMarketCap and DeFiLlama now show USDe around $6.4 billion, in line with that trend.
Binance’s oracle failure, not a wholesale depeg
The catalyst for scrutiny was a dramatic intraday print on Binance. During the October 10 crash, USDe traded as low as $0.65 in the USDe/USDT pair on the exchange, even as major on-chain pools on Curve, Fluid and Uniswap held near $0.99, according to both Blockworks Advisory and CoinDesk.
Ethena founder Guy Young blamed Binance’s internal oracle. In comments reported by Cointelegraph, he said Binance quoted USDe using its own thin order book rather than deeper external venues, which amplified selling and drove the local price to $0.65 while minting and redemptions stayed functional across DeFi. Binance later pledged to overhaul that pricing setup.
Blockworks’ post on Ethena governance backed that claim. It described the Binance print as a short-lived dislocation, noted that USDe stayed within a narrow band on decentralized exchanges, and pointed out that Aave saw only tens of thousands of dollars in liquidations tied to USDe and sUSDe during the window.
Yield reflexivity starts to bite
The deeper problem sits in Ethena’s design. USDe backs itself with delta-hedged positions across centralized and decentralized venues rather than cash, as laid out in the protocol’s technical documentation and token listings on CoinMarketCap and CoinGecko. Funding from short perps, plus staking yield where applicable, funnels to sUSDe holders as yield.
When funding runs hot, traders mint USDe, stake it, and build leveraged carry trades around it. When funding collapses, that same loop runs in reverse. A November 10 report from DL News, citing DeFiLlama data, found that USDe’s circulating supply fell roughly 40% over a month, from almost $15 billion at the start of October to about $8.5 billion, as funding and risk appetite faded.
Colin Butler of Mega Matrix, which holds USDe exposure, told DL News that low or negative funding compresses protocol revenue and staked USDe yields, making the token less appealing than idle dollars. Keyrock researcher Amir Hajian added that USDe demand tracks that yield almost one-for-one. When yields drop, redemptions follow. That flywheel pushed USDe higher through 2025’s bull run. It now drives exits.

MacPherson’s view aligns closely with current reality. USDe’s cap now sits in that range, after overshooting to $15 billion at the top of the carry trade.
Where the contagion risk actually sits
Even after the drawdown, USDe remains the third largest dollar-pegged token behind USDT and USDC, with a stablecoin market share that still places it near the core of DeFi, according to DL News and Coingecko research. That size amplifies any feedback into lending markets that leaned hard into USDe yield loops.
Aave risk advisor Chaos Labs warned in August that Aave carried roughly $4.7 billion of exposure tied to USDe-backed assets, including sUSDe and Pendle PT positions, equal to more than 55% of USDe’s then supply. The Block later highlighted how a popular Pendle–Aave loop let users lock sUSDe yield, borrow against the position on Aave, buy more USDe or sUSDe, and repeat. That structure turbocharged USDe’s climb. It also concentrates risk.
Chaos Labs and LlamaRisk both flagged a simple failure mode. Ethena has deposited part of its own backing capital, including USDC and USDtb, into Aave as well. In a contraction, Ethena may need to pull those funds to honor USDe redemptions at the same time loopers rush to exit. That combination can spike borrow rates, drain Aave liquidity, and feed back into broader DeFi risk.
So far, the hard data shows stress, not collapse. Ethena’s risk committee says the reserve fund remained intact through the October and November redemption waves, and governance posts report no operational losses while USDe supply fell from $14.3 billion to just above $7 billion. Aave avoided mass liquidations linked to USDe during the October 10 event, and USDe’s peg has held near $1 on major venues ever since.
The price action still sends a clear message. Ethena built USDe on a funding-dependent carry trade. October’s crash and the rate reset that followed put that model through its first full cycle at scale. Capital listened. It left.
