The Regulatory Frontier Designing the Rules that Shape Innovation 2025

Introduction: The new competitive battleground When Brazil’s Central Bank, Banco Central do Brasil (BCB), launched Pix, a nationwide instant payment system, in 2020, it made a deliberate regulatory decision to build public payment rails where the market had not done so. Payments were costly and fragmented, so the BCB designed and operated a 24/7 instant payment platform open to all licensed institutions. Mandatory participation by major banks ensured reach, while open standards and minimal fees promoted inclusion and competition. Within a year, Pix had become Brazil’s dominant retail payment channel, with over 150 million registered users, demonstrating how regulators can act as platform stewards when the foundational infrastructure is missing.1 The model also highlighted a governance challenge – how a regulator can drive change and oversee the system it governs while preserving neutrality and trust. Few markets have matched this pace of adoption; BCB acted as a catalyst, setting the direction, building shared rails and moving the market players in one direction. Pix is not just a payment reform. In today’s economy, regulation functions as infrastructure – its architecture determines how fast innovation scales, where capital flows and which countries set the standards that others must follow. However, most regulatory systems were built for a different era of stable products, national markets and linear change. Today’s technologies – and cross-sectoral and national boundaries – evolve continuously, leaving static rulebooks struggling to keep pace. The result is a widening gap between innovation and policy, where outdated regulation risks either slowing growth or ceding influence to faster-moving jurisdictions. The tensions are intensifying. New technologies, such as artificial intelligence (AI), biotechnology, quantum computing and autonomous systems, are advancing faster than existing regulations. A handful of technological and pharmaceutical giants dominate markets once governed nationally, prompting governments to reassert their authority. Global data flows and supply chains have made purely national rulebooks obsolete, while repeated privacy breaches and misinformation crises have eroded confidence in self-regulation. At the same time, regulation itself has become a tool of geopolitical competition as the European Union, the US, China and other rising powers vie to set global norms. Innovation presents both opportunities and risks simultaneously, making regulatory design a central element of economic resilience. Speed alone is not the answer. It’s important to move quickly to regulate innovation, but doing so without adequate safeguards is bound to invite backlash in the form of bans, financial or legal delays and political pushback. That could set innovation back even more than doing nothing would have. At the same time, the guiding philosophy shouldn’t be deregulation per se, but to design systems that keep pace with the speed of innovation while maintaining public safety and trust. Getting the timing right is critical. Regulators need to act early enough to shape emerging markets, yet design rules can evolve as evidence accumulates. Setting rules too late or locking them in too rigidly can hinder innovation and lead to costly revisions. Constant shifts, however, create uncertainty that stalls investment. What matters is predictable evolution – clarity about what will be reviewed, when and why. The most effective regulations grow through dialogue, testing, feedback and refinement, and are developed with the market, not imposed on it. Pix is not an isolated case. In every major sector, from finance to health and mobility, the same challenge is emerging. Regulators are under pressure to adapt frameworks that can evolve as technologies do. Their capacity to do so will increasingly define competitiveness, trust and economic leadership. Designing intelligent regulatory infrastructure begins with five domains – the areas of choice that determine how regulation will perform in practice. Building the infrastructure of innovation and aligning it with trust will determine who leads the next era of growth. The Regulatory Frontier: Designing the Rules that Shape Innovation 5
