DeFi Stablecoins Are Breaking One by One

DeFi Stablecoins Are Breaking One by One — Here’s Every Depeg You Should Know About

• Nearly half a dozen decentralized stablecoins have lost their pegs in 2025.

• The first week of November alone saw three major stablecoin depegs triggered by DeFi exploits.

• Combined, the depegs wiped out hundreds of millions in value and shattered investor confidence.

The cracks are starting to show in decentralized finance’s (DeFi) foundation.

In what’s shaping up to be DeFi’s worst stretch since the Terra-LUNA collapse of 2021, multiple stablecoins have lost their dollar pegs recently — some dipping as low as a few cents before partial recoveries.

From liquidity crunches to outright exploits, 2025 has become a stress test for DeFi stablecoins.

Why Do Stablecoins Depeg?

For all their promise of “stability,” DeFi stablecoins live on a fragile foundation of algorithms, incentives, and liquidity.

Most rely on complex loops — borrowing, staking, and re-depositing collateral — to maintain their peg.

When confidence falters or collateral prices drop too fast, the whole structure begins to unravel.

There are three common failure points:

Liquidity Crises:

When too many holders try to redeem their tokens at once, liquidity pools dry up.

This forces automated market makers (AMMs) to sell collateral at a discount, driving the peg even lower.

Collateral Shock:

Many stablecoins are backed by volatile assets like Ethereum (ETH) or Bitcoin (BTC).

When those prices fall, the collateral ratio shrinks, and redemptions can outpace recovery mechanisms — a problem that doomed Terra’s UST and continues to haunt similar designs.

Smart Contract or Oracle Failures:

Exploits, bad price feeds, or flawed code can send even a well-collateralized coin into a free fall.

When protocols like Balancer or Curve are compromised, the shock spreads across DeFi through interconnected pools.

A Perfect Storm for Depegs

The first week of November alone saw a wave of depegs ripple across the market, wiping out hundreds of millions in value and triggering flash liquidations across lending platforms.

Most of the affected coins weren’t traditional fiat-backed tokens like USDT or USDC — those only saw minor, short-lived dips.

The casualties were DeFi-native designs, including synthetic, algorithmic, or yield-bearing coins built on complex, interlocking systems.

When one protocol faltered, the rest tumbled like dominoes.

The early November Balancer exploit alone triggered liquidity black holes across Euler, Morpho, and Lista — the kind of “looping contagion” analysts have warned about since the last cycle.
