Collateral-and-Margin Liquidity Command Leader

The mandate

A rates-and-basis shock produced intraday variation-margin calls far above desk and entity forecasts. The group held nominally sufficient securities, but eligibility, location, settlement timing and legal-entity ownership made much of it unavailable before clearing deadlines. The collateral treasurer resigned during the post-event review, opening a ten-month seat before the next stress season and regulatory liquidity assessment.

The interim leader will establish one command model for forecast, call validation, eligible inventory, transformation, mobilisation, funding and escalation across clearing houses and legal entities. Work must connect trade sensitivities, margin models, settlement cut-offs, encumbrance, concentration, wrong-way risk and operational capacity. The window also requires revised stress overlays and executable playbooks for concurrent calls rather than a larger static liquidity buffer.

A permanent markets treasury executive will be appointed by month six and command the final two simulations under observation. Handover requires that successor to challenge a disputed call, choose between collateral transformation and cash funding, and present entity impacts to the asset-liability committee. The transfer includes inventory semantics, counterparty routes, stress assumptions, decision logs, operational constraints and remaining concentration exposures.

This seat can direct daily margin-liquidity command, set mobilisation priorities, stop non-essential encumbrance, move funding within approved limits, require call validation and escalate trading constraints to accountable officers. It cannot change market-risk limits, override legal-entity governance, approve new counterparties, waive settlement or regulatory controls, sign repo documentation or accept liquidity risk beyond established appetite.

The remit excludes acting as head of market risk, clearing operations or collateral technology and excludes unilateral restriction of a trading desk. Success means calls are forecast within useful ranges, eligible assets arrive before deadlines, entity resources remain visible, simulations expose real constraints and the permanent leader can manage stress without a private network of manual instructions.

Why this seat is open

The event showed that aggregate liquidity and high-quality asset totals were poor proxies for cash that could reach a clearing house on time. Leadership departure left fragmented teams protecting their own forecasts and inventory. Temporary command authority is needed to integrate treasury and operations immediately, challenge false availability and develop permanent leadership through observed intraday decisions rather than a calm-period transition.

What you will own

• Reconstruct margin calls from portfolio sensitivities, clearing methodology, intraday recalculation, disputes and settlement deadlines.
• Establish eligible collateral inventory by legal owner, location, encumbrance, haircut, concentration, settlement route and mobilisation time.
• Integrate collateral transformation, secured funding, cash buffers and trading constraints into time-stamped decision ladders.
• Define stress overlays for basis gaps, wrong-way moves, simultaneous counterparties, payment congestion and failed asset settlement.
• Run simulations at operational cut-offs, measuring forecast error, call validation, asset arrival, decision latency and entity impact.
• Exercise delegated funding and mobilisation rights while recording escalation, dissent and accountable risk acceptance.
• Induct the successor through live and simulated command and transfer playbooks, routes, counterparties and unresolved weaknesses.

Candidate qualifications

• Has commanded collateral and intraday liquidity for a clearing member during severe market stress and concurrent margin calls.
• Understands CCP models, variation and initial margin, eligibility, haircuts, settlement, repo, transformation and legal-entity constraints.
• Has exposed the difference between reported liquid assets and collateral deliverable at a specific venue and deadline.
• Can integrate trading sensitivities, treasury funding and collateral operations without appropriating independent risk oversight.
• Has led realistic simulations involving disputed calls, failed settlement, concentration and cross-currency funding under time pressure.
• Demonstrates succession through a permanent treasurer who exercised funding choices before the interim mandate concluded.

Non-negotiables

• Will work onsite in London and attend every clearing-house simulation and quarterly cross-region review.
• Must disclose relationships with banks, clearing houses, custodians, repo counterparties, collateral vendors and trading firms.
• Brings live intraday margin command in cleared markets; general corporate cash management does not qualify.
• Will not treat an asset as liquidity until ownership, eligibility, settlement route and arrival time are evidenced.
