We argue that the explanatory gap is conceptual rather than empirical: the dominant analytical apparatus treats capital as a quantity to be mobilized rather than as a structure to be matched. Three literatures — sustainability transitions research, blended finance and mission-oriented innovation policy, and the systems-thinking leverage-points tradition — supply the elements of a structural account but have not connected them at the level required to address the coupling question directly. This paper develops the Capital-Mediated Systems Transitions (CMST) framework to occupy that boundary position. We theorize capital not as a resource but as time-coupled energy directed at the system state; define a Capital-Coupling Coefficient κ as the ratio of the capital horizon to the transformation horizon, anchored to exogenous roadmap data; and derive two coupling-conditional outputs — system outcome Ω and capital at risk R — connected through a constitutive cross-output ξ mechanism. From the κ-mechanic we develop a portfolio-level apparatus: a Θ-signature characterizing themes across four axes, a categorical marker system that resists spurious-precision optimization, a sub-critical-opportunity construct, and six portfolio metrics. Six hierarchically ordered hypotheses render the framework partially falsifiable, and a three-stream research program is identified. The paper's distinctive contributions are the securitisation-as-κ-engineering reading that reclaims a much-criticized financial technology as a positive coupling-design tool; the sub-critical-opportunity construct that makes visible the highest-leverage allocation candidates conventional below-threshold filters systematically exclude; and the cross-output ξ mechanism that makes coupling failure a constitutive — not merely statistical — cause of both Ω-failure and R-failure. capital architecture transformation finance blended finance sustainability transitions coupling coefficient capital-coupling coefficient systems transformation G11 G24 G32 O38 Q54 https://capital-architecture.institute/research/wp-001 https://capital-architecture.institute/research/wp-001 Wed, 15 Apr 2026 00:00:00 GMT Tobias Temmen Global private markets hold over USD 13 trillion in dry powder and assets under management (Preqin, 2024); cumulative blended-finance mobilisation reached USD 213 billion by 2023 (Convergence, 2024). Yet across blended finance, private credit, energy transition, defense and dual-use, and deep-tech credit, the same pattern recurs: capital is available, deployment stalls. The existing literature supplies instrument taxonomies, policy norms, fund-design tools, and tranche-calibration models, but no end-to-end practitioner methodology that converts a financing requirement into a bankable, replicable capital structure. This paper introduces the Capital Architecture Framework (CAF): a seven-stage lifecycle with documented outputs and Quantitative Gate Requirements (QGRs) at each stage, calibrated against ILPA DDQ 2.0 governance documentation standards (ILPA, 2023) and Bank of England guidance on private-credit stress-testing (BoE FSR, 2024). The Framework distinguishes Capital Architecture, as a discipline of structural design, from product innovation, advisory practice, and impact-finance taxonomy. The paper advances three claims. First, the binding constraint on capital deployment in transitional and emergent asset classes is architectural, not supply-side. Second, replicability must be designed from Stage 1; it cannot be retrofitted at Stage 5. Third, Minimum Concessionality and the Mobilisation Multiplier are design variables under practitioner control, not market outcomes. The implication is that practitioners structuring blended-finance vehicles, private-credit funds, and deep-tech debt instruments may adopt the Framework as a methodology of construction, and institutional LPs and DFIs may adopt it as a diagnostic against which proposed structures are evaluated. blended finance capital architecture private credit structured development finance tranche design mobilisation multiplier minimum concessionality
