What Is Circuit Breaker?
A circuit breaker is a mechanism that temporarily halts trading when prices move beyond predetermined thresholds. In traditional markets, circuit breakers trigger at 7%, 13%, and 20% intraday declines. In crypto, most spot exchanges lack circuit breakers (24/7, unregulated), but some derivatives exchanges (CME, some CEX perps) implement cooling-off periods during extreme volatility.
How Circuit Breaker Works
The absence of circuit breakers in most crypto markets contributes to their extreme volatility. Without trading halts, liquidation cascades can drive prices down 30-50% without interruption, as there's no forced pause for participants to reassess. This makes crypto flash crashes both more severe and more common than in traditional markets.
Why It Matters for Traders
The lack of universal circuit breakers in crypto means: stop-losses can execute at dramatically worse prices during cascading selloffs, leverage is more dangerous (no pause before liquidation), and flash crashes can be more extreme. Traders must build their own "circuit breakers" through: maximum daily loss limits, reducing leverage during volatile periods, and using options for tail risk protection instead of relying on stops that may gap through.
