Parametric VAR Limitations

Limitation

Parametric Value at Risk models, within cryptocurrency derivatives, rely heavily on distributional assumptions regarding asset returns; these assumptions, often based on historical data, frequently fail to capture the non-stationary and fat-tailed characteristics inherent in digital asset markets, leading to underestimated risk exposures. The inherent reliance on pre-defined parametric distributions restricts the model’s ability to adapt to evolving market dynamics and unforeseen events, particularly relevant given the rapid innovation and regulatory shifts within the crypto space. Consequently, the accuracy of VAR estimates diminishes during periods of high volatility or structural breaks, potentially misleading risk managers and traders.
