In Ring-Fencing, Professor Steven Schwarcz provides an insightful overview of the concept of “ring-fencing” as a “potential regulatory solution to problems in banking, finance, public utilities, and insurance.” As Professor Schwarcz explains, “ring-fencing can best be understood as legally deconstructing a firm in order to more optimally reallocate and reduce risk.” Ring-fencing has gained particular prominence in recent years as a strategy for limiting the systemic risk of large financial conglomerates (also referred to herein as “universal banks”). Professor Schwarcz describes several ring-fencing plans that have been adopted or proposed in the United States, United Kingdom, and European Union.
This Comment argues that “narrow banking” is a highly promising ring-fencing remedy for the problems created by universal banks. Narrow banking would strictly separate the deposit-taking function of universal banks from their capital markets activities. If properly implemented, narrow banking could significantly reduce the safety net subsidies currently exploited by large financial conglomerates and thereby diminish their incentives for excessive risk-taking.
