Dear IBEX members,

Hereby, we would like to inform you that due to the upcoming series of non-working days during Christmas and New Year holidays, IBEX EAD has updated the day factor used in our margin model for the calculation of collateral calls on the day ahead and intraday market segments as follows:

  1. The value of the day factor shall be 3, as of 21/12/2022.
  2. The value of the day factor shall be reduced to 2, as of 03/01/2023.

The value of the other risk parameter – risk price, remains unchanged.

You could find the updated versions of Instruction No4 “Method for calculation of required collateral” and collateral call calculator on the IBEX website.

The adjustment implemented is in line with Art. 229 of the Power exchange operational rules.
