$2B Ethena USDe depeg exposes cracks in crypto’s ‘synthetic dollar’ system

Ethena’s synthetic dollar, USDe, shed over $2 billion in market capitalization after briefly losing its dollar peg on Binance. The flash event exposed structural risks in crypto’s stablecoin plumbing.

According to CryptoSlate data, USDe’s market value dropped from $14.8 billion on Oct. 10 to $12.6 billion by Oct. 12.

The decline coincided with a Binance pricing glitch that also affected wrapped assets like wBETH and BNSOL, temporarily breaking their links to underlying tokens.

At one point, USDe fell to $0.65 before recovering to parity. Binance later said it had reimbursed users over $283 million for losses related to the incident.

Inside the flash depeg

USDe’s price dislocation came amid one of crypto’s largest liquidation events this year.

Crypto markets experienced a steep sell-off after US President Donald Trump pledged a 100% tariff on Chinese imports, wiping out over $20 billion in digital-asset open interest. The resulting rush into safe havens like gold drained risk appetite and exposed weak points in leveraged crypto markets.

USDe’s structure depends on the basis trade that involves shorting perpetual futures while holding long spot exposure through reserves in USDT and USDC. When funding rates fall sharply, this mechanism yields lower returns and puts redemption pressure on the system.

Still, the project insists the depeg was localized to Binance and not systemic.

Dragonfly’s Haseeb Qureshi noted that USDe “did not depeg” globally, by pointing out that:

“While USDe wicked down on every CEX, it did not do so uniformly. Bybit briefly hit $0.95 then quickly recovered, yet Binance depegged a crazy amount and took forever to regain the peg. Curve meanwhile dipped a mere 0.3%.”

Moreover, Ethena Labs founder Guy Young confirmed that mint and redemption remained operational throughout, processing $2 billion in redemptions within 24 hours.

He also pointed out that the asset’s primary on-chain liquidity pools, such as Curve, Uniswap, and Fluid, showed fewer deviations, while $9 billion in collateral (mostly USDT and USDC) remained available for instant redemption.

Considering this, Young said:

“I do not think it is accurate to describe this is a USDe depeg when a single venue was out of line with the deepest pools of liquidity that experienced no abnormal price deviations whatsoever.”

Why this matters for Bitcoin

Although USDe is not marketed as a conventional stablecoin, its expanding role in crypto’s financial plumbing means even small pricing errors can have disproportionate effects.

The past weekend’s disruption proved how a venue-specific malfunction can ripple through markets and cause real losses.

And since USDe is now embedded in several DeFi protocols and centralized exchanges, a short-term gap between its market value and the dollar can spill into other liquidity pools.

Such disruptions can trigger forced liquidations in lending markets, reduce liquidity in BTC and ETH trading pairs, and distort the reference price used across decentralized platforms.

Considering this, OKX founder Star Xu cautioned that the market must recognize what USDe represents, a tokenized hedge fund that is not a “1:1 pegged stablecoin.”

According to him:

“Such funds typically employ relatively low-risk strategies such as delta-neutral basis trading or money-market investments, but they still carry inherent risks — including ADL events, exchange-related incidents, and custodian security breaches.”

Xu noted that platforms using USDe as collateral must apply adaptive risk controls rather than treating it like traditional stablecoins. He argued that ignoring the asset’s structural nuances could introduce systemic exposure to the broader crypto market and turn a localized fault into a sector-wide crisis.
