Margin Call Agent

Calculates exposures, issues and agrees margin calls across the portfolio.

Runs the daily margin cycle: recalculates exposure against each CSA, issues the call (or agrees the inbound one), and books the movement before the agreement deadline. Agrees calls A2A with counterparty collateral agents; call amounts above threshold are re-derived by an oversight agent before issuance.

Illustrative workflow

How the work moves

Starting point

End-of-day exposure shift on a bilateral OTC portfolio breaches the CSA threshold.

  1. 01

    Recalculate exposure against the CSA; net against existing collateral and MTA.

  2. 02

    Compute the call amount; cross-check against the counterparty's expected number.

  3. 03

    Issue the call to the counterparty's agent (A2A); track to agreement.

Result

Issues an agreed margin call before the deadline and hands the funding movement to the optimizer; a valuation gap instead opens a dispute with evidence attached.

Checks and boundaries

What must be tested or reviewed

  1. 01Exposure calc independently re-derived; discrepancies above tolerance open a dispute, not a call.
  2. 02Call amounts above a threshold are re-derived by an oversight agent before issuance.
  3. 03Deadline guardrail: unagreed calls nearing the CSA cut-off escalate.
  4. 04Immutable audit of every call issued/agreed and the supporting exposure.

Human authority

An accountable reviewer commits the decision or action.
