Abstract

The United States financial system can be restructured by giving universal direct access to credit risk-free central bank money. In the 10 years since the financial crisis, technological advancements and regulatory tools have laid the foundation for Central Bank Digital Currencies to emerge as this economic resolution. Our paper analyzes similar economic cases and contends that introducing Central Bank Digital Currencies (CBDCs) can improve financial stability without degrading credit availability in the long term. We illustrate this by focusing on similar market shifts, namely in the U.S. student loan market and the New Zealand agribusiness sector. Our analysis showcases that by introducing CBDCs, market participants can subsequently remove certain market subsidies that promote poor risk practices and improper pricing. This subsidy to financial institutions is both explicit in the form of FDIC deposit insurance and implicit in the stipulation of taxpayer funded bailouts that materialized in 2008. We calculate the effect of introducing CBDCs by focusing on historical market examples when similar fundamental market shifts happened. Our conclusion is that CBDCs may diminish credit availability, but this effect is ameliorated as financial stability improves in subsequent years. Accordingly, we recommend a roadmap for rolling out CBDCs in the least disruptive fashion.
