Circuit Breaker

Definition ∞ A circuit breaker in financial markets is an automatic regulatory mechanism designed to temporarily halt trading activity when prices move beyond a predetermined threshold within a specified timeframe. Its purpose is to mitigate panic selling or buying, providing participants a pause to assess market conditions. This intervention aims to prevent excessive volatility and maintain orderly market operation. Such mechanisms are common in traditional and increasingly in digital asset exchanges.
Context ∞ The implementation of circuit breakers in cryptocurrency exchanges is a topic of ongoing discussion, particularly during periods of extreme market volatility. While some argue they protect investors from rapid, cascading liquidations, others contend they interfere with the free market principles of digital assets. Regulatory bodies often consider circuit breakers a tool for market stability, influencing how digital asset trading platforms design their operational safeguards.
