Fintech, Cryptocurrencies, and CBDC: Financial Structural Transformation in China”
Fintech and decentralized finance have penetrated all areas of the financial system and have improved financial inclusion in the last decade. In this paper, we review the recent literature on fintech, cryptocurrencies, stablecoins, and central bank digital currencies (CBDCs). There are important implications from the rise of fintech and the introduction of stablecoins and CBDCs in recent years. We provide an overview of China’s experience in fintech, focusing on payments, digital banking, fintech lending, and the recent progress on its CBDC pilots (e-CNY). We also discuss important ...

A Comment on Monetary Policy and Rational Asset Price Bubbles
Galí (2014) showed that a monetary policy rule that raises interest rates in response to bubbles can paradoxically lead to larger bubbles. This comment shows that a central bank that wants to dampen bubbles can always do so by raising interest rates aggressively enough. This result is different from the Miao, Shen and Wang (2019) comment on Galí’s paper. They argue Galí’s model contains additional equilibria in which more aggressive rules dampen bubbles. We show that for these equilibria, more aggressive rules involve threats to raise interest rates more than actual rate increases.

Bank competition and the role of regulation
Market discipline for financial institutions can be imposed not only from the liability side, as has often been stressed in the literature on the use of subordinated debt, but also from the asset side. This will be particularly true if good lending opportunities are in short supply, so that banks have to compete for projects. In such a setting, borrowers may demand that banks commit to ?monitoring? by requiring that they use some of their own capital in lending, thus creating a market-based incentive for banks to hold capital that stems purely from the asset side of the bank?s balance sheet. ...

Enhancing prudential standards in financial regulations
The financial crisis has generated fundamental reforms in the financial regulatory system in the U.S. and internationally. Much of this reform was in direct response to the weaknesses revealed in the precrisis system. The new ?macroprudential? approach to financial regulations focuses on risks arising in financial markets broadly, as well as the potential impact on the financial system that may arise from financial distress at systemically important financial institutions. Systemic risk is the key factor in financial stability, but our current understanding of systemic risk is rather limited. ...

Competition and financial stability
Competition policy in the banking sector is complicated by the necessity of maintaining financial stability. Greater competition may be good for (static) efficiency, but bad for financial stability. From the point of view of welfare economics, the relevant question is: what are the efficient levels of competition and financial stability? We use a variety of models to address this question and find that different models provide different answers. The relationship between competition and stability is complex: sometimes competition increases stability.

On Interest Rate Policy and Asset Bubbles
In a provocative paper, Gal (2014) showed that a policymaker who raises interest rates to rein in a potential bubble will only make a bubble bigger if one exists. This poses a challenge to advocates of lean-against-the-wind policies that call for raising interest rates to mitigate potential bubbles. In this paper, we argue there are situations in which the lean-against-the wind view is justified. First, we argue Gal?s framework abstracts from the possibility that a policymaker who raises rates will crowd out resources that would have otherwise been spent on the bubble. Once we modify Gal?s ...
