Systems Over SignalsMoney/Financial infrastructure/Autonomous systems
The future of money is a question of architecture.
As value moves through new rails and software begins to act on behalf of people and organisations, questions once considered separately are becoming inseparable: who can authorise an action, which institution carries the risk, what a protocol makes possible, and how trust survives across boundaries.
Systems Over Signals examines the design choices beneath these shifts and what they mean for the people who build and operate financial systems.
- Payments and settlement infrastructure
- Agentic payments and delegated authority
- Digital public infrastructure
- Trust and governance in financial systems

-
Delegated Economic Authority
When software begins to purchase, negotiate and pay on behalf of people or organisations, an authenticated account is not always enough to explain what the software was permitted to do. This essay separates identity, delegated spending authority and execution, and explores the governance conditions required when authority must cross institutional boundaries.
-
When Transaction Models Become Payment Infrastructure
Transaction foundation models turn payment behaviour into a reusable representation that can inform several downstream decisions beyond fraud detection. The essay asks what changes when a shared upstream model shapes multiple rules and controls, and where validation, accountability and institutional oversight should sit.
-
The Protocol Default
Early standards choices in agentic payments may become enduring defaults, even before the industry has settled deeper questions of trust. This article compares emerging approaches and examines how developer adoption, ecosystem incentives and path dependence can determine tomorrow’s machine-payment architecture.
-
Programmability Is Eating Settlement
Shorter settlement cycles can change liquidity needs, reconciliation work, risk allocation and business models built around delayed movement of funds. The essay uses emerging payment and asset-settlement examples to examine what becomes possible and what still requires institutional coordination.

India’s digital economy can be read through the systems that connect its platforms, sectors and institutions. This essay looks past iconic digital stacks toward interoperability, governance and the slower structural forces that could determine future outcomes.
-
Agentic DPI: The Moment Interfaces Become Infrastructure
AI agents can change public-service infrastructure when they move beyond helping people navigate services and begin acting across institutions on their behalf. The essay examines identity-bound delegation, consent, auditability and the public-governance choices that must precede deployment at scale.
