Abstract: Systems and methods are provided for determining liquidations costs for portfolios of financial instruments. Survey data for liquidation costs at different risk profiles is received from market participants. An initial attempt is made to hedge part of the portfolio. Some hedges may not be available during market stress conditions. A warehousing cost for warehousing the unhedged portion of the portfolio is determined and a re-hedge cost for hedging the partially hedged portfolio when hedges are available is determined. A liquidation cost is a combination of the hedge cost, the warehousing cost and the re-hedge cost. Weighting for Greek ladder may be created by mapping liquidation costs to Greek ladders. Lookup tables may be created from liquidity cost. The lookup tables may be used to look up for liquidity cost using aggregated Greek generated by weighted sum of Greek ladder and provide a simplified mechanism for determining liquidation costs.

Abstract: The disclosed embodiments relate to reducing, minimizing or otherwise optimizing margin requirements for a trader having both an interest rate (IR) futures and over-the-counter (OTC) interest rate swaps (IRS) accounts by efficiently allocating IR futures across both accounts.

Abstract: A margin requirement determination for a financial product, a market price of which varies with volatility of a market value of an underlying instrument, includes determining a realized variance of the market value for each completed trading interval based on return data for the underlying instrument, calculating, for each completed trading interval, a respective implied variance of the financial product based on option trade data for the underlying instrument, computing a respective loss risk value for a corresponding trading interval of the completed trading intervals, each respective loss risk value being derived from a first deviation between the realized variance of the corresponding trading interval and the implied variance of a preceding completed trading interval, and a second deviation between the implied variance of the corresponding trading interval and a succeeding completed trading interval, and determining the margin requirement based on a subset of the loss risk values.
