Portfolio Margin Basis

Capital

Portfolio margin basis represents the minimum equity a trader must maintain in their account when utilizing leverage for cryptocurrency derivatives, options, and other financial instruments. This requirement is determined by a risk-based model assessing potential losses across the entire portfolio, rather than individual positions, offering a more holistic view of systemic risk. The calculation incorporates sensitivities to market movements, considering correlations and non-linear exposures inherent in derivative contracts, and is crucial for maintaining market stability. Exchanges dynamically adjust this basis based on volatility and liquidity conditions, influencing trading costs and available leverage.
