Disruptive Technology and Securities Regulation

Nowhere has disruptive technology had a more profound impact than in financial services — and yet nowhere more do academics and policymakers lack a coherent theory of the phenomenon, much less a coherent set of regulatory prescriptions. Part of the challenge lies in the varied channels through which innovation upends market practices. Problems also lurk in the popular assumption that securities regulation operates against the backdrop of stable market gatekeepers like exchanges, broker-dealers and clearing systems — a fact scenario increasingly out of sync in 21st century capital markets. This Article explains how technological innovation not only “disrupts” capital markets — but also the exercise of regulatory supervision and oversight. It provides the first theoretical account tracking the migration of technology across multiple domains of today’s securities infrastructure and argues that an array of technological innovations are facilitating what can be understood as the disintermediation of the traditional gatekeepers that regulatory authorities have relied on (and regulated) since the 1930s for investor protection and market integrity. Effective securities regulation will thus have to be upgraded to account for a computerized (and often virtual) market microstructure that is subject to accelerating change. To provide context, the paper examines two key sources of disruptive innovation: 1) the automated financial services that are transforming the meaning and operation of market liquidity and 2) the private markets — specifically, the dark pools, ECNs, 144A trading platforms, and crowdfunding websites — that are creating an ever-expanding array of alternatives for both securities issuances and trading.

Fintech and the Innovation Trilemma

Whether in response to robo advising, artificial intelligence, or crypto-currencies such as Bitcoin, regulators around the world have made it a top policy priority to supervise the exponential growth of financial technology (or “fintech”) in the post-crisis era. However, applying traditional regulatory strategies to new technological ecosystems has proved conceptually difficult. Part of the challenge lies in managing the trade-offs that accompany the regulation of innovations that could, conceivably, both help and hurt consumers as well as market participants. Problems also arise from the common assumption that today’s fintech is a mere continuation of the story of innovation that has shaped finance for centuries. This Article offers a new theoretical framework for understanding and regulating fintech by showing how the supervision of financial innovation is invariably bound by what can be described as a policy trilemma. Specifically, we argue that when seeking to provide clear rules, maintain market integrity, and encourage financial innovation, regulators have long been able to achieve, at best, only two out of these three goals. Moreover, today’s innovations exacerbate the trade-offs historically embodied in the trilemma by breaking down financial services supply chains into discrete parts and disintermediating traditional functions using cutting edge, but untested, technologies, thereby introducing unprecedented uncertainty as to their risks and benefits. This Article seeks to catalogue the strategies taken by regulatory authorities to navigate the trilemma, and posits them as operating across a spectrum of interrelated responses. The Article then proposes supplemental administrative tools to support not only market, but also regulatory experimentation and innovation.
