The financial crisis of 2008 has led to dramatic changes in the way that finance is regulated: the Dodd-Frank Act imposed broad and systemic regulation on the industry on a level not seen since the New Deal. But the financial regulatory reforms enacted since the crisis have been premised on an outdated idea of what financial services look like and how they are provided. Regulation has failed to take into account the rise of financial technology (or "fintech") firms and the fundamental changes they have ushered in on a variety of fronts, from the way that banking works, to the way that capital is raised, even to the very form of money itself. These changes call for a wide-ranging reconceptualization of financial regulation in an era of technology-enabled finance. In particular, this Article argues that regulators' focus on preventing the risks associated with "too big to fail" institutions overlooks the conceptually distinct risks associated with small, decentralized financial markets. In many ways, these risks can be greater than those presented by large institutions because decentralized fintech markets are more vulnerable to adverse economic shocks, less transparent to regulators, and more likely to encourage excessively risky behavior by market participants. The Article concludes by sketching out a variety of regulatory responses that better correspond to fintech's particular risks and rewards.

The global financial crisis of 2008 ushered in the most sweeping reform of financial regulation in the United States since the New Deal. Alarmed by the systemic risk that financial institutions posed to the broader economy, as well as perceived abuses engendered by the "too big to fail" mindset among banking executives, legislators moved quickly to impose a slew of new requirements on the financial sector. These reforms, passed under the umbrella of the Dodd-Frank Act, drastically altered the regulatory landscape for financial institutions.1 Wall street firms found themselves subject to a bewildering array of new regulatory requirements, from restrictions on proprietary investing (the so-called Volcker Rule), to obligatory stress testing of banks' ability to withstand various crisis scenarios, to more stringent reporting requirements.
At the same time that Congress was focused on fixing Wall street, dramatic changes were taking place in a less well-known and still emerging sector of the financial world: the...
