Abstract
Abstract
Capital is abundant. Structure is scarce. The financing gap in complex, transitional, and emergent asset classes is not a supply problem. It is a design problem.
Existing frameworks — from OECD DAC Principles to IFC instrument taxonomies — provide policy norms and instrument catalogues. None provides a practitioner methodology for designing a layered capital structure from the mandate up.
This paper introduces the Capital Architecture Framework (CAF): a seven-stage lifecycle methodology for the systematic design, deployment, and scaling of layered capital structures across blended-finance, private-credit, special-situations, and deep-tech mandates.
The CAF is instrument-agnostic and mandate-driven. It begins with the topology of the financing need and derives the optimal capital stack from first principles. It provides quantitative governance standards, intercreditor design requirements, additionality testing, valuation governance, and a Global North application framework — the first published methodology to make explicit the structural equivalence of blended-finance logic across emerging and developed markets.
The paper draws on published evidence from OECD, IFC, BIS, IMF, Convergence, ILPA, FCA, and the Bank of England, supplemented by illustrative hypothetical structures. It is designed for capital-markets practitioners, DFI investment officers, institutional LP allocators, and academic researchers in structured finance and development finance.
Where it sits in the discipline
Wo es in der Disziplin sitzt
CAF is the operational extension of the discipline named on this site as Capital Architecture. Where the discipline page describes the practice and the glossary names its instruments — Mandate Cartography, Mobilisation Multiplier, Minimum Concessionality, Mandate Readiness Assessment — the working paper sets out the seven-stage lifecycle through which those instruments are sequenced into a working structure. It is also published as the inaugural working paper of the Capital Architecture Institute ↗.
CAF ist die operationelle Erweiterung der hier als Capital Architecture benannten Disziplin. Während die Disziplin-Seite die Praxis beschreibt und das Glossar ihre Instrumente benennt — Mandate Cartography, Mobilisation Multiplier, Minimum Concessionality, Mandate Readiness Assessment — legt das Working Paper den siebenstufigen Lifecycle dar, durch den diese Instrumente zu einer funktionierenden Struktur sequenziert werden. Es ist zugleich das eröffnende Working Paper des Capital Architecture Institute ↗.
