Fire Sale Dynamics

Fire sale dynamics occur when market participants are forced to sell assets at significant discounts due to margin calls or liquidity constraints. This selling pressure forces prices below their fundamental value, which can then trigger more margin calls for other participants who hold the same assets.

This creates a downward spiral that can affect the entire market, not just the assets being sold. In the context of clearinghouses, fire sales are a major risk because they can rapidly erode the value of collateral held by the clearinghouse.

Preventing these dynamics requires robust circuit breakers and sufficient liquidity buffers. It is a classic example of how individual rational actions lead to collective irrational outcomes.
