From Currency Dominance to Infrastructure Power: Modular Monetary Systems, Protocol Governance and the Double Foundation of Infrastructure Power

This conceptual working paper examines how monetary power can be redistributed across financial, digital, institutional and physical infrastructure without requiring sovereign currencies to disappear. It distinguishes transactional dependence from balance-sheet dependence and considers how independently developed systems can acquire complimentary functions through interoperability. The paper develops five linked concepts: the Modularisation of Monetary Power, Intergration Without Unification, Functional Convergence Without Common Intent, the Double Foundation of Infrastructure Power and the Infrastructure Power Heuristic. The heuristic provides a comparative framework for assessing how quickly capability can become usable economic power through the interaction of cross-border reach, usable capacity, strategic choice and time to deployment. It is a directional framework, not a calculated forecast. Cases including Nexus, Mandala, Agorá, mBridge, Aadhaar, UPI, cross-border digital identity arrangements, Treasury and gold markets, data centres, semiconductors, energy systems and critical minerals are used to examine technical possibility, instiutional direction, governance and dependency. The paper argues that interoperability can reduce dependence at the transaction layer while preserving or relocating dependence beneath it. No complete alternative monetary architecture has emerged. Removing an intermediary currency does not remove power from the system. It relocates it.
