Cross Margining Support

Cross margining (XM) allows a combined initial margin calculation between fixed income listed (i.e. FI ETD) and OTC IRS positions.


  • Delivers collateral efficiency through margin offsets between OTC IRS and FI ETD positions.

CrossMargine Q3.2

XM can only be enabled for EUR and CHF denominated instruments (trades).

No, only the forward-looking parts, i.e. the Initial Margin (IM) requirement.

In general, ETD positions have a holding period of two days (HP2) and OTC positions have a holding period of five days (HP5).

  • ETD positions from the HP2 group will be assigned to the HP5 group to allow for offsetting between IRS and ETD.
  • For this, an algorithm runs every two hours to check whether / which ETD positions should switch to a HP5 in order to achieve the maximum XM benefit.
  • A detailed description of the allocation procedure can be found in the Cross-Margining User-Guide (chapter 4.6 “Algorithmic description of Cross Margining allocation”).

Yes, the XM benefit can be calculated via: 

  • Prisma Margin Calculator 
    • Access to Eurex’ production / simulation environment is needed.
    • Can be used for a What-If analysis (against already existing positions) via GUI or API connection.
  • Cloud Prisma Margin Estimator
    • Openly accessible
    • Provides highly accurate estimation and helpful to get a general idea about the margin.
    • Availability cannot be guaranteed (Eurex Cloud PME Terms of Use apply here).

  • General information can be found on our website.
  • A more detailed margin calculator user guide as well as templates and field descriptions for the upload files can be found on the Member Section via: Resources > Eurex Clearing > Documentation & Files > Eurex Clearing Documents > EurexOTC Clear > System Documentation > GUIs.
