SD-11.4 — Margin & Collateral Operations

Business Domain: BD-11 Treasury, Cash & Collateral (Middle office) · Applies: BOTH

Purpose

Runs the daily margin-and-collateral cycle — calculating what is owed, calling and responding, and moving the collateral that satisfies it. SD-11.4 is the operational engine of collateral management: it calculates variation and initial margin on cleared and uncleared positions, issues and responds to margin calls, checks proposed collateral against the eligibility schedules, settles the collateral movement, processes substitutions, and resolves disputes and fails. Margin is the obligation; collateral is the asset that satisfies it; SD-11.4 runs the workflow that connects them. It is not the firm-wide optimisation of which collateral to post — that is SD-11.5 — and it does not initiate the derivative or financing trade that creates the exposure, which are SD-06.6’s and SD-11.8’s.

Service Operations

• Calculate margin — compute variation and initial margin on cleared and uncleared derivative and financing positions, against the CCP and the bilateral CSA.
• Issue and respond to margin calls — raise the firm’s calls and respond to counterparty and CCP calls, agreeing the amount.
• Check collateral eligibility — validate proposed collateral against the eligibility schedules, haircuts and concentration limits.
• Settle collateral movements — instruct and confirm the pledge, receipt and return of collateral, including triparty settlement.
• Process substitutions — handle the substitution of posted collateral when an asset is recalled or a better one is available.
• Resolve disputes and fails — investigate margin-call disputes and collateral-settlement fails to resolution.

Inputs and outputs

• Inputs: derivative and financing positions from SD-12.14 and SD-11.8; the master agreements and CSA terms (DR-03); clearing relationships (DR-05); valuations and exposure from BD-08 and BD-07; the collateral-allocation decision from SD-11.5.
• Outputs: margin calls, collateral movements and the margin-and-collateral balance (DR-04) — consumed by SD-11.2 Liquidity Management (a margin call is a near-term funding obligation), SD-11.5, SD-07.2 Credit & Counterparty Risk Management, SD-12.10 Reconciliation, and SD-08.5 Valuation Adjustments & Reserves.

Entities

• Consumes: DR-03 Master Agreement, DR-05 Clearing Relationship, DR-01 Listed Derivative, DR-02 OTC Derivative, E-01 Legal Entity (counterparties); the SD-11.5 collateral-allocation decision; the SD-11.8 derivative and financing positions; the SD-12.14 derivative and financing positions; PM-14 Direct Loan (from SD-04.12 — the directly-originated facility whose cash-flow accounting on draws, interest and repayments runs through the margin-and-collateral cycle).
• Owns: DR-04 Margin & Collateral Balance — the per-relationship record of margin owed and collateral held; SD-11.4 both owns it and calculates it.

Standards

• The ISDA Master Agreement and the Credit Support Annex — the bilateral legal substrate of uncleared collateral.
• The BCBS-IOSCO margin framework and the Uncleared Margin Rules; EMIR and Dodd-Frank clearing-and-margin.
• The triparty-collateral model — the triparty agents and the ECB AMI-SeCo harmonisation work.

Open extensions

• The margin-calculation sub-model — CCP versus bilateral CSA.
• The dispute-and-fail workflow.
• The Service-Operation-level input/output contracts.
