Margin Requirement Distortion

Calculation

Margin Requirement Distortion arises when the computed margin requirement for a derivative position deviates from levels justified by underlying risk factors and prevailing market conditions. This discrepancy can stem from model inaccuracies, particularly in capturing tail risk or correlations between assets, leading to underestimation of potential losses. Exchanges and clearinghouses employ sophisticated algorithms, yet these are susceptible to parameter miscalibration or unforeseen market events, creating a divergence between theoretical and applied margin levels. Consequently, distorted margin requirements can induce systemic risk, encouraging excessive leverage or premature liquidation of positions during periods of heightened volatility.
