# Flash Crashes ⎊ Area ⎊ Resource 4

## What is the Event of Flash Crashes?

These are characterized by extreme, rapid price depreciation across an asset class or market segment, often occurring within minutes or even seconds. Such occurrences expose latent leverage and liquidity shortfalls within the trading environment. Identifying the triggers for these dislocations is a key focus of market surveillance.

## What is the Liquidity of Flash Crashes?

A defining feature of these rapid declines is the sudden evaporation of order book depth, which prevents large orders from executing at expected prices. This lack of available counterparties exacerbates the initial price move through cascading liquidations. Market makers must model the probability of such liquidity traps.

## What is the Speed of Flash Crashes?

The velocity of price discovery and subsequent automated risk management responses, such as margin calls and forced liquidations, drives the severity of the event. In crypto derivatives, the interconnectedness of leveraged positions can create positive feedback loops that accelerate the downward trajectory. Prudent risk control anticipates this rapid contagion.
