Derivatives exchanges present leverage as a capability, offering sliders or dropdowns with preset multipliers. However, the arithmetic relationship between leverage and fees determines outcomes on these platforms. Exchanges earn fees on notional value, which means a leveraged position generates more revenue than an unleveraged one funded with identical collateral.
Trading fees and leverage
Fees on derivatives venues are charged as a percentage of notional value, not the margin posted to open a position. A trader using 50 times leverage pays fees on $50,000 of notional, from a $1,000 deposit. This multiplier applies to funding as well, making a persistently crowded side expensive at a rate proportional to the chosen leverage.
Liquidation risks
Leverage compresses the distance between the entry price and the point at which collateral no longer supports the position. At 50 times leverage, a 2% adverse move can exhaust the margin. In crypto markets, 2% intraday moves are routine, making high-leverage positions vulnerable to ordinary noise.
Asymmetry and risk
Stop-loss orders do not reliably protect high-leverage positions in fast markets. Furthermore, when a liquidation cannot be cleared, venues reduce positions on the profitable side, ranking candidates by unrealised profit and effective leverage. This ranking indicates that venues consider high-leverage positions as expendable, treating them as a liability marker in their risk engine.
