A 3% Token Decline Unleashes $36 Million in Ethereum DeFi Liquidations

Add to Google Preferred Sources
A decline of roughly 3% in PT-reUSD, a principal token issued on Pendle, triggered about $36 million in liquidations on the Ethereum-based lending platform Morpho early Tuesday, August 25, 2026. The move followed a large purchase of the corresponding yield token YT-reUSD by one wallet, which drove the implied annual yield to 20% and pushed the principal token’s price lower. Borrowers had repeatedly used PT-reUSD as collateral to borrow USDC and buy more PT-reUSD, leaving their leveraged positions with less than 3% of protection against liquidation. Thirty-three liquidation events occurred within a 14-minute window, repaying $36.14 million of debt, with the USDC market accounting for $35.19 million. Pendle said its oracle functioned as designed, while Steakhouse Financial reported that lenders suffered no losses and no bad debt was created. The episode highlights how leverage sensitivity, rather than price magnitude, determines liquidation risk in on-chain lending markets.

Key Elements

A decline of roughly 3% in a single yield-token was enough to trigger about $36 million in liquidations on the Ethereum-based lending platform Morpho early Tuesday, August 25, 2026, exposing how thinly buffered leveraged positions in decentralized finance can unwind on moves that would barely register in most markets.

The collateral at the center of the episode was PT-reUSD, a principal token issued on Pendle and tied to reUSD, a dollar-denominated asset that pays interest to holders. The token fell after one wallet made a large purchase of the corresponding yield token, YT-reUSD, driving the implied annual yield up to 20% before selling out of the position shortly afterward, according to blockchain security firm PeckShield.

Pendle’s structure allows holders to split an interest-paying asset into two separate tokens. The principal token, or PT, is a claim on the original money, redeemable for a dollar’s worth at a set date — in this case December 10, 2026. The yield token, or YT, collects the interest earned between now and then. The two behave like a seesaw: because both are carved out of the same asset, their prices must add up to the whole. When buyers pile into the yield side, they effectively bid up the interest, and the principal side has to get cheaper to compensate.

That dynamic set off a chain reaction in Morpho’s lending markets. Some traders had deposited PT-reUSD as collateral, borrowed the stablecoin USDC against it, bought more PT-reUSD with the borrowed money, and repeated the loop. Each round increased the potential return while shrinking the margin for error. Borrowers running this strategy had left themselves less than 3% of headroom before their loans would be closed out automatically.

When the token’s price fell, 33 liquidation events occurred between 04:37:47 and 04:51:23 UTC, repaying $36.14 million of debt. The liquidations were concentrated in the USDC market, which accounted for $35.19 million of the debt repaid, while the USDT market accounted for $956,000. Liquidators seized 38.6 million principal tokens across the 33 events.

The affected Morpho market held $67.5 million of collateral against $52.2 million of borrows, while the Pendle reUSD pool had $8.97 million of liquidity Those figures describe different parts of the system: the Morpho number covers collateral and borrowing in the lending market, while the Pendle figure is pool liquidity, so they are not directly comparable measures of market depth or exposure

Oracle Design Determined the Trigger Point

The price Morpho used to make liquidation calls came from an oracle that took whichever of two numbers was lower: PT-reUSD’s average trading price over the previous 15 minutes, or a fixed schedule climbing gradually toward $1 at maturity. The fixed schedule acted as a cap, preventing PT-reUSD from being valued above the price implied by its path toward $1 at maturity. When the market price fell below that curve, the 15-minute average became the lower number and took over.

The market’s liquidation threshold was 91.5% setting the point at which positions became eligible for liquidation. That construction meant a relatively small market price decline could determine collateral valuation and push leveraged positions past the threshold

Pendle said the oracle was configured correctly and functioned as intended. Steakhouse Financial, which curates lending markets that accept PT-reUSD as collateral, said lenders in its vaults were unaffected and no bad debt was created, meaning the liquidations raised enough to repay the loans. Steakhouse pulled its money out of the affected markets while it examined what happened, then began putting it back. The underlying reUSD asset remained unaffected

Leverage Sensitivity, Not Price Magnitude

The episode underscores a core lesson for DeFi participants: liquidation is a function of health factor, not headline volatility. A position levered near its maximum loan-to-value can breach its liquidation threshold on a single-digit percentage repricing, which is why a sub-5% move translated into an eight-figure unwind.

Collateral pressure compounds when liquidators sell seized assets into the same falling market, tightening prices further and pulling adjacent positions toward their own thresholds. That reflexive loop is the mechanism behind cascading liquidations, and it is why the dollar total outran the price trigger.

For traders, the near-term implication is positioning discipline. Health factors carried close to the liquidation line convert routine volatility into forced exits. Until buffers widen, Ethereum DeFi positions remain sensitive to moves far smaller than the losses they can produce.
