Capital Attrition

Capital attrition in the context of financial derivatives and cryptocurrency markets refers to the gradual erosion of trading capital due to persistent frictional costs and losses. It occurs when a trader or protocol experiences a steady reduction in net asset value caused by trading fees, slippage, funding rate payments in perpetual swaps, or the continuous decay of options premiums.

Unlike a sudden liquidation event, attrition is a slow, often unnoticed drain that impacts long-term profitability. In cryptocurrency, this is exacerbated by high volatility and the cost of maintaining margin positions during market stagnation.

Effective risk management requires tracking this attrition to ensure that the cost of maintaining a position does not exceed the expected return. It is a critical metric for evaluating the sustainability of leveraged trading strategies.
