Amongst major economies, China has been taking a lead in the development of central bank digital currency (CBDC), which has generated widespread interest and impact around the globe. China’s CBDC, commonly known as e-CNY, is designed with several distinctive features, enabling it to compare favorably to other payment methods such as credit cards, mobile payment, unbacked cryptocurrency, and stablecoins. A variety of social, economic, political, and regulatory reasons can be identified to help explain China’s active pursuit of CBDC. However, the prospect of success will be affected by many factors and may vary between the domestic and international markets. This paper argues that the adoption of eCNY will likely succeed domestically, but may face more challenges in the international markets. The development of e-CNY seems to have created a catfish effect on other major economies in the race for CBDC. It is not fully clear, however, that the CBDC race will be better explained by the first-mover or the late-mover advantage theory. The CBDC project will have both public and private law implications, and several legal issues warrant particular attention in relation to the legal status of CBCD, the role and responsibility of the central bank, legal remedies for losses suffered by CBDC users from cybersecurity issues and operational problems, and the issue of data privacy and protection.

This study investigates the influence of mobile payment application use on crime rates. Using a unique database of verdicts from criminal courts in China and an index measuring the extent of mobile payment usage, we find that a one standard deviation increase in mobile payment adoption and usage leads to an 11% decrease in the theft rate. Furthermore, the effect of widespread mobile payment adoption on theft rates is more pronounced in areas characterized by a higher prevalence of cash transactions. These findings suggest that the decrease in cash circulation in society due to mobile payment use can reduce incentives for theft. However, we do not find evidence linking mobile payment usage to other types of criminal activity, including robbery, arson, brawling, homicide, and serious injury by vehicle.

Financial repression—regulating interest rates below the laissez-faire equilibrium—has historically impeded investment in developing economies. In China, bank deposits were long subject to binding interest rate caps. Using transaction and local penetration data from a leading FinTech payment company, we study the FinTech’s introduction of a money market fund (MMF) with deposit-like withdrawal features but uncapped interest rates aids in interest rate liberalization. In aggregate, MMF assets grow rapidly, and banks whose deposit base was more exposed to the payment app see greater outflows. These outflows are concentrated in household demand deposits, for which the MMF is the closest substitute. Contrary to regulator concerns, exposed bank profitability does not decline. Rather, exposed banks invest more in financial innovation and are more likely to launch competing funds with similar features. Our results highlight how FinTech competition stimulates interest rate liberalization among traditional banks by introducing competition for funding.
