An analyst on Twitter said USDe tumbled to $0.65 versus USDT and $0.62 versus USDC during today’s crash, though it later traded around $0.97 against USDC. The move hit secondary markets such as Binance.
The drop followed news about new China tariff measures tied to former President Trump, which triggered a broad market sell-off.
Analysts and protocol contributors say the plunge exposed a structural flaw in synthetic dollar designs and showed how price oracles can become risk oracles.
The issuers continued to process mints and burns and remained overcollateralized throughout.
Price Shock on Secondary Markets
USDe’s secondary market price briefly slid to near two-thirds of its pegged value. That low came as traders rushed to sell amid the wider market panic. The quoted low points were $0.65 against USDT and $0.62 against USDC.

Within hours, the price recovered toward $0.97 against USDC, but the episode left market participants shaken.
Why This Happened?
Observers point to a lack of atomicity between the spot asset and the corresponding short position. That means the synthetic dollar can move sharply when markets shift.
One commentator noted that the core issue is structural rather than a specific protocol bug. The asset was still overcollateralized. It kept minting and burning. Yet the secondary price can diverge far from the peg when liquidity is thin or when short positions reprice.
How Oracles and Pricing Methods Played a Role?
A key voice in the discussion said that a price oracle is also a risk oracle. When an off-chain or secondary-market price swings wildly, systems that rely on that feed can face cascading problems.
In this case, a pricing methodology developed by Chaos Labs and adopted after debate inside the DAO helped prevent large losses. That method reportedly saved about $4.5 billion in positions on Aave and reduced liquidation costs by roughly $180m for users.
The approach relied on the Ethena Proof of Reserve oracle and deep protocol analysis to keep liquidations from spiralling.
What Does This Mean?
The episode underscores a simple point. Synthetic dollars are not the same as physical dollars. One analyst warned that you cannot safely use these tokens as payment assets when they can swing from 2% to 38% in value.
You also cannot confidently wrap them as collateral for a payment asset if the wrapped token can vary so much. That creates real risk for big trades. Settling a multi-billion dollar deal with a token that can deviate by tens of percent is dangerous.
