The Regulatory Frontier Designing the Rules that Shape Innovation 2025

Regulator as platform stewardWhat the role must deliver Regulators move from enforcing rules to shaping the systems that make markets work Provide foundational infrastructure Catalyse public digital rails where markets cannot (e.g. in payments, data exchange or identity): lower entry barriers, widen reach and enable scale. Ensure open and neutral access Keep participation on equal terms through published standards, interoper- able APIs, and non-discriminatory entry rules (no gatekeeping by incumbents).Maintain trusted governance Run the infrastructure with clear accountability, independent oversight and transparent performance data to sustain confidence.India’s Unified Payments Interface (UPI) shows both the power and disruption of regulator- built infrastructure. Launched in 2016 under the oversight of the country’s central bank and operated by a separate non-profit entity, UPI created open, free-for-users payment rails that connect banks, fintechs and consumers in real time. By 2024, it was handling over 16 billion transactions a month – over 80% of India’s retail digital payments by volume. The model drove financial inclusion at unprecedented speed, but compressed the margins and market shares of the traditional card networks. Similar logic applies to digital identity systems.8 Where markets lack a trusted identity layer, regulators often step in to establish common credentials that enable secure access and participation across sectors.The design tension lies between inclusion and neutrality. Regulator-run infrastructure may widen participation and lower costs, but it risks politization and the crowding out of private investments. Private-sector systems innovate faster, but risk fragmentation and concentration. The challenge is to maintain competitive neutrality, ensuring that public platforms stay open while allowing private providers to innovate atop them. Shared infrastructure fails less from design than from governance. When regulators operate public platforms, their conduct becomes the benchmark for the private sector, with weak accountability eroding trust faster than technical failure. The standards that regulators set while running shared systems ultimately shape how markets judge the fairness and reliability of governance itself. Rules that cannot adapt lose both consumer trust and relevance. Modern legislation must hold principles steady while allowing technical standards and enforcement to evolve with evidence and technology. Principles-based law creates stability without rigidity. Prescriptive regulation specifies methods that may soon become obsolete. Meanwhile, principles-based frameworks set guiding norms, such as fairness, transparency and accountability, and delegate detailed outcomes and metrics to technical bodies that can update them without reopening legislation. The US Food and Drug Administration’s Software-as-a-Medical-Device Framework applies broad safety principles while relying on technical standards developed by the International Medical Device Regulators Forum, keeping oversight aligned with rapid innovation.9 Continuous authorization replaces one-time approval. Most licensing regimes treat digital systems as static, even though software, data models and safety profiles constantly evolve. The Accumulus Synergy initiative, a global collaboration between pharmaceutical regulators and companies, offers a new model: a shared data platform that allows version-controlled regulatory information to flow in real time.10 Each update becomes visible as it occurs, enabling supervisors to focus on those changes that materially affect risk. Supervision turns from periodic reporting into continuous dialogue, aligning regulatory vigilance with technological advancements. Balancing legal certainty with adaptability is a central design challenge. Prescriptive rules give businesses the confidence to invest – but if they never change, they lose relevance as technology advances. Principles give regulators flexibility, yet they make compliance boundaries less predictable. A key way to manage this tension is through technological neutrality, designing rules that focus on purpose and function rather than the underlying technology. This allows frameworks to stay relevant as systems evolve and standards adjust over time. Laws lose credibility when adaptation lags. When standards bodies take years to update their principles, they stop providing protection. When regulators interpret them differently across regions, companies face costly fragmentation. The worst outcome is a system that claims flexibility but creates uncertainty. The five design domains above show how regulatory choices shape the speed, safety and competitiveness of innovation. Together, they form the framework on which markets grow and trust is earned, and define what is at stake when nations design the rules of the future. 1.5 Keeping the law adaptive, so trust and relevance endure Prescriptive rules give businesses the confidence to invest – but if they never change, they lose relevance as technology advances.
