Derivatives Expiry Contagion

Derivatives expiry contagion refers to the systemic risk where volatility or failures originating from the expiry of a large volume of contracts propagate to the broader market. When significant open interest is concentrated in a single expiry, the forced liquidation or hedging activity required by market makers can cause extreme price swings.

These swings can trigger margin calls and cascade liquidations across other correlated assets or protocols. In the context of cryptocurrency, this is exacerbated by the interconnectedness of lending protocols and decentralized exchanges.

Contagion occurs when the liquidity required to satisfy expiry obligations is insufficient, leading to slippage that impacts the collateral value of other market participants. Understanding this phenomenon is crucial for risk managers who must anticipate liquidity crunches during high-expiry periods.

It highlights the importance of diversified expiry dates and robust margin requirements.
