## Portfolio VaR Constraints

Portfolio Value at Risk (VaR) Constraints are limits placed on the maximum expected loss of a portfolio over a specific time horizon at a given confidence level. These constraints act as a hard boundary for risk-taking, forcing traders to reduce exposure if the potential loss exceeds the predefined threshold.

In the context of crypto derivatives, VaR is often difficult to calculate due to the fat-tailed nature of price distributions and the potential for rapid liquidity evaporation. Implementing VaR constraints helps prevent catastrophic losses by ensuring that the portfolio remains within the risk appetite of the firm or individual.

It is a standard tool for institutional risk oversight and compliance.
