Ethena's USDe stablecoin briefly slumped roughly 8% against Tether's USDT on Binance's spot market early Tuesday, falling to $0.9202 in an episode that revived memories of October 2025, when the synthetic dollar lost its peg on the same platform. At the time of reporting, USDe had recovered to $0.9996, containing the slide to a matter of minutes.

The dip came shortly before Binance began an infrastructure wallet upgrade, during which the exchange suspended deposits and withdrawals across all networks for about an hour starting at 6 a.m. UTC, while spot and futures trading remained open. Notably, nothing suggests the USDe price slide was connected to the maintenance window.

Did USDe suffer another depeg?

Analysts tracking USDe's price against USDT on Binance's spot market flagged a brief wobble in the USDE/USDT pair between 05:00 UTC and 05:04 UTC, with the price dipping as low as $0.9202. The stablecoin snapped back toward its $1 target within minutes of the 8% slide, which was visible only on Binance's order book. Prices did not move abnormally on-chain or across deeper liquidity pools — the pattern that separates a single venue's dislocation from a token-wide depeg.

USDe is the synthetic dollar issued by Ethena, which maintains its $1 peg by pairing crypto collateral with short futures positions rather than the cash reserves that back conventional stablecoins such as USDT and USDC.

Why did USDe lose its dollar peg again?

On-chain analysts have put forward varying theories about the mechanics behind the red wick on Binance's USDE/USDT chart, but many point to thin exchange liquidity rather than any problem with Ethena's collateral. Order-book depth is the crux: a pair only holds its printed price as firmly as the liquidity behind it, so a large market sell into a shallow book can push the last traded price well away from $1 until other traders step in to absorb it.

One explanation came from Punk (@punk2898 on X), among the first traders to spot the slide. He suggested that a market sell order of roughly $8 million in USDe hit a shallow order book, printing the drop on the charts before other traders absorbed the position. Punk estimated that someone on the other side pocketed about $600,000 in three minutes, and called on Binance warn users before such large market orders execute.

Another trader monitoring the situation, CM (@chenmo on X), made the same point about Binance's thin USDe book. According to CM, that combination is where the risk began spreading during Binance's October incident.

Not the same as the October 2025 crash

Tuesday's slide brought back memories of the October 2025 depeg, when USDe fell to as low as $0.65 on Binance. That episode unfolded in the middle of a market-wide liquidation event that Cryptopolitan reported wiped out more than $19 billion in positions held by 1.6 million traders in a single day.

Binance attributed part of the chaos to a display glitch that showed some tokens at $0 and compensated affected users with about $283 million.

Ethena Labs CEO Guy Young went on X at the time to push back on the “depeg” narrative, writing that it was “not accurate to describe this as a USDe depeg when a single venue was out of line with the deepest pools of liquidity.”

Binance responded by pledging to fold asset redemption prices into its reference index and to add a soft price floor for USDe, a measure aimed at keeping quoted prices near the peg. CM also noted that the exchange added the stablecoin's actual redemption price to its reference index rather than reading order-book quotes alone — a change that, in theory, should prevent a repeat of that episode. How that index-based pricing performs the next time a large order hits Binance's USDe book is the open question Tuesday's episode leaves behind.

A repeat of the October 2025 incident would carry further-reaching effects now that the stablecoin's utility has spread beyond DeFi. BlackRock added the token to its Aladdin platform in June, joining BTC and ETH products as the only crypto assets available to Aladdin's institutional users.
