Margin Requirement Scaling
Margin Requirement Scaling is a risk management mechanism where the amount of collateral a trader must post increases as their position size grows. This tiered approach is designed to penalize excessive leverage and discourage the accumulation of dangerously large positions.
By forcing traders to lock up more capital for larger exposures, exchanges create a financial disincentive for extreme concentration. This system protects the protocol from insolvency if a large trader is liquidated, as the increased margin provides a larger buffer to cover potential losses.
It acts as a circuit breaker for individual accounts, ensuring that the total leverage in the system remains within sustainable bounds. This mechanism is frequently used in perpetual futures contracts to manage the systemic risk posed by high-leverage whales.
It aligns the trader's financial risk with the potential impact their position could have on the broader market.
