Abstract

Over the past two decades, the emergence of giant technology firms (Bigtechs) has disrupted the traditional way that financial markets operate. These technology giants have leveraged network effects, massive amounts of data, and extensive customer bases to expand into the financial sector and rapidly achieve economies of scale and scope. The expansion of Bigtechs into finance has reinforced the pre-existing trends of digitalization and datafication in finance, which has evolved into a new era of the platformization. With a substantial presence in financial markets, the development of digital finance platforms has enormous potential for enhancing financial inclusion, efficiency and sustainable development. Despite these benefits, there are also many issues and risks in relation to their involvement in financial services, such as the emergence of new “too-big-to-fail” and “too-connected-to-fail” problems and the development of new systemically important financial institutions (SIFIs). In this context, the question is how policymakers and regulators, along with industry and consumers, can effectively leverage the benefits of the platformization of finance while mitigating its risks and negative impacts.

This article focuses on the experience and lessons learned from China, in particular, as it has been a pioneer in the platformization of finance. As the potential problems arising from Bigtechs’ market dominance and economies of scale have become increasingly prominent, they have become the focus of a multi-pronged response from the Chinese government, particularly from the second half of 2020. In the context of digital finance, risks involved in platform-based and highly interconnected financial activities are being addressed via multiple areas of law, including finance, competition and antitrust, data protection and cybersecurity. Based on the Chinese experience, the broad cross-sectoral and rapidly evolving nature of Bigtech businesses requires a reconsideration of the complex interaction between different government policies and regulatory objectives.

Drawing from the lessons of China’s experience, this article frames a number of strategies and recommendations for other jurisdictions that are exploring ways to regulate the emergence of the platformization of finance. Firstly, due to the rapidly evolving nature of Bigtech businesses, it is important to develop regulatory mechanisms that allow for timely review and adaptation to facilitate understanding of innovative financial services before risk events occur. Secondly, the exclusive control of customer data by Bigtechs is likely to undermine competition in financial markets, thus requiring effective data sharing mechanisms, such as Open Finance initiatives, to break data monopolies. Furthermore, given their combination of network effects and economics of scope and scale, digital finance platforms are in increasing cases becoming systemically important. There is a need for both activity-based and entity-based regulations to address risks involved in the interconnected financial businesses of these new SIFIs.
