Portfolio VAR Models, or Value-at-Risk models, are analytical tools applied to a collection of crypto assets and derivatives. Their primary function is to quantify the maximum potential loss a portfolio could experience over a specified time horizon, such as one day, at a given statistical confidence level, typically 95% or 99%. This provides a standardized measure of downside risk.
Mechanism
These models employ various statistical techniques, including historical simulation, parametric (variance-covariance) methods, or Monte Carlo simulation, to estimate the distribution of potential portfolio returns. The underlying system aggregates all positions, explicitly accounts for correlations between assets, and applies chosen parameters to calculate the VaR figure. Daily or intra-day recalculations provide continuous risk assessment, ensuring current market conditions are considered.
Methodology
The strategic approach uses VaR as a standardized measure for aggregate market risk across diverse crypto holdings and trading strategies. This methodology provides a concise, quantitative summary of downside risk exposure, significantly aiding capital allocation decisions, establishing appropriate risk limits, and informing stress testing scenarios. Its framework supports institutional risk management by offering a standardized metric for comparing risk across different portfolios and asset classes.
