Systemic Impact of Depegs

A depeg occurs when a digital asset, typically a stablecoin intended to maintain a 1:1 value with a fiat currency, loses that parity. The systemic impact refers to the cascading risks and financial instability triggered by this failure.

Because stablecoins act as the primary liquidity layer for crypto-derivatives and decentralized finance protocols, a depeg forces mass liquidations. These liquidations trigger margin calls across lending platforms, causing a sudden spike in selling pressure.

As assets are sold to cover positions, the price drops further, potentially triggering more liquidations in a feedback loop. This phenomenon threatens the solvency of protocols holding the depegged asset as collateral.

It creates contagion that spreads from decentralized exchanges to centralized lending desks. Ultimately, the systemic impact erodes trust in the protocol's ability to maintain its peg, leading to bank runs.

Such events highlight the vulnerability of algorithmic and under-collateralized stablecoin models.
