IRGiT allows Clearing House Members to estimate and forecast the amounts of collateral margins required by IRGiT through the use of the IRGiT Margin Calculator.The calculator supports both approximate calculation of the margins currently required by the Clearing House as well as simulations concerning the predicted deposit amounts depending on changes in clearing prices.
The amount of collateral margins is set for a Clearing House Member in accordance with the regulations in effect in the Clearing House, taking into account the netting used (with the exception of netting within Power Groups and cross-period netting).
IRGiT notes that the simulation results are provided for illustrative purposes only and must not be treated as the ultimate margin requirements calculated by the Clearing House.
Currently IRGiT offers two types of calculators:
Margin Calculator for portfolios
The calculator supports estimated calculation of margins for actual Clearing House Member portfolios, which may consist of both purchase and sale transactions. The calculator is available separately for the Electricity Forward Market (EFM) and the Gas Forward Market (GFM) operated within the OTF.
Please read the User Manual of the Margin Calculator for portfolios in the sheets entitled “Instructions” in the files containing the calculator.
Margin Calculator for individual instruments
The margin calculator for individual Forward Market instruments supports easy estimation of the amount of required margins for a single transaction in a given forward instrument. Given the contract price, IRGiT clearing price and the number of contracts, it is possible to estimate the required value of the initial margin and variation margin for that instrument.
Please read the User Manual of the Margin Calculator for single instruments on the Electricity Forward Market in the sheets entitled “Instructions” in the files containing the calculator.
