Prime Brokerage Business Architecture Toolkit

A 420+ capability business architecture toolkit for Prime Brokerage, structured across three hierarchical levels — Level 1 (strategic domains like Securities Lending, Financing & Margin, Custody & Clearing, and Capital Introduction), Level 2 (capability groups), and Level 3 (operational detail) — with 26 end-to-end value stream maps and a business data model covering core entities like Client Fund, Position, Margin Account, and Securities Loan. Delivered in PowerPoint, Word, and Excel, with a dedicated capability-definitions document and a KPI set mapped at Level 2.

Why You Can't Prompt Your Way to This

Prime brokerage doesn't manage money — it finances and services the firms that do, and that distinction changes almost every capability underneath it. Securities lending alone is a business within the business: matching borrows to loans, managing rehypothecation rights, and pricing hard-to-borrow names are capabilities with no equivalent in a typical broker-dealer or asset manager. Financing runs through synthetic structures — total return swaps, CFDs, and other instruments that let a hedge fund get exposure without owning the underlying security — which most generic financial-services models never touch because they're specific to how funds actually take leverage. Cross-margining across equities, fixed income, and derivatives positions, and calculating exposure on a gross and net basis simultaneously, requires a risk and collateral architecture that doesn't map cleanly onto retail or commercial banking capability lists. Capital introduction — connecting hedge fund clients to prospective investors — is a relationship and matchmaking capability that exists almost nowhere else in financial services, and a generic prompt has no reason to know it belongs here at all. That combination of financing, custody, synthetic risk, and capital-raising support under one roof — each with its own regulatory and operational logic — is why this map runs deeper than a typical single-purpose broker-dealer capability list.

Inside the Toolkit

• Business Capabilities Map — 420+ capabilities across Level 1 (strategic), Level 2 (tactical), and Level 3 (operational), spanning securities lending, financing & margin, custody & clearing, and capital introduction, in PowerPoint, Word, and Excel
• Capability Definitions — a standalone reference so "rehypothecation," "cross-margining," and "synthetic financing" mean the same thing to trading, risk, and client-service teams
• Capability KPIs — measurable indicators mapped at Level 2, so maturity assessments hold up across financing, custody, and risk functions
• Value Stream Maps — 26 end-to-end flows spanning client onboarding, securities borrow/loan matching, margin & collateral management, and trade settlement
• Business Data Model — core entities (Client Fund, Position, Margin Account, Securities Loan, Collateral, Counterparty) and their relationships, ready to anchor a data or systems architecture

Where It Gets Used

• Baseline capability maturity ahead of a prime services platform consolidation or multi-prime technology build-out
• Scope margin, collateral, or securities-lending system RFPs against actual capability gaps instead of vendor feature lists
• Separate financing, custody, and capital-introduction capabilities cleanly when a bank is standing up or expanding a prime business
• Give risk, technology, and client-service teams a shared reference for how counterparty exposure and collateral actually flow

Built For

Enterprise and business architects, prime services and risk leaders, and technology strategists at banks and broker-dealers who need a reference model built around how financing, custody, and capital introduction actually function for hedge fund clients, not a generic capital-markets template.
