Abstract: This article examines how digital payment innovation and supporting initiatives, such as infrastructure and regulation, can foster micro, small, and medium enterprise (MSME) access to finance. This expanded access in turn supports broader sustainable development as reflected in the United Nations Sustainable Development Goals (SDGs). Achieving these goals requires thoughtful consideration and management of technological and a range of other risks and impacts across jurisdictions and governance levels.
Digital payment platforms serve as collectors, aggregators and (in some cases) providers of MSME financial and other data. This supports lending, low-cost agent-assisted financial transactions, financial products, and services by conventional banks, micro-finance institutions (MFIs), and non-bank financial institutions. Importantly, the data provided by these platforms can facilitate cash flow analysis and factoring (a form of alternative credit data) in which MSMEs use receivables as collateral (complementing other forms of collateral, such as real properties) to access finance within traditional lending institutions or elsewhere.
As consumer confidence in e-commerce platforms boosts the digital presence of MSMEs, new markets for MSMEs (particularly small retail shops, such as “mom-and-pop” stores providing last-mile services to unbanked and underserved segments in remote areas) emerges. Yet, there have been increasing concerns among policymakers and regulators at national, regional, and international levels......(Please click here to read the full text.)

Abstract: As one of the most digitalized sectors of the economy, finance is increasingly dependent on data. Over the past decade, the implementation of Open Banking and Open Finance in an increasing number of major jurisdictions around the world, including the European Union (EU), the United Kingdom (UK), Australia, Brazil, and the United Arab Emirates (UAE), seeks to break down data silos, empower consumers, and increase competition among financial service providers, aiming to maximize the value of financial data for innovation, growth, and competitiveness. In addition to mandatory requirements, other governance approaches to Open Finance, including collaborative arrangements and voluntary initiatives, are emerging. For example, Singapore and Hong Kong are actively supporting the development of Open Finance through collaboration between regulators and industry, while both China and India are seeking to develop new approaches to making data available to support development, innovation, and competitiveness. In the United States (US), industry associations have promoted Open Finance practices, and a new mandatory rule from the Consumer Financial Protection Bureau (CFPB) on personal financial data rights is currently pending.
There are complex problems in the interaction between financial regulation and data governance in Open Finance. Customer data shared through an Open Finance system is both subject to financial regulatory requirements, such as rules governing the collection, processing, and use of financial data, and to the general governance framework for data protection. Furthermore, Open Finance initiatives adopted by different jurisdictions affect information sharing in domestic financial markets and in the cross-border transfer of financial data. The trend towards data localization and the asymmetry of data sharing leads to an unlevel playing field between market players, thereby exacerbating the problem of regulatory fragmentation in Open Finance regimes. Given the evolving nature of digital finance and the complexity of integrating data into its process, the main challenge is to develop appropriate governance approaches that can maximize the benefits of data sharing while mitigating new cross-cutting challenges in finance and data regulation.
Based on an analysis of experiences to date in leading jurisdictions, we synthesize a range of policy strategies to address the complex interplay of financial regulation and data governance inherent in building Open Finance. These hold important lessons also for the US as it moves forward. The multi-disciplinary nature of Open Finance requires coordination between regulators and industry to ensure policy coherence and technical interoperability. Where financial and data regulatory regimes intersect, it is important to establish a collaborative forum and/or provide general guidance to facilitate a better understanding of Open Finance governance and improve consistency in regulatory action across sectors. In response to the increasing digitalization of the economy, there is also the need to expand the scope of data sharing from the financial sector to other industries, and thus move towards a broader Open Data framework.
"Centralization in Decentralized Finance: Systemic Risk in the Crypto Ecosystem and Crypto’s Future as a Regulated Industry"

Introduction: A paradigm shift is manifesting in the global crypto ecosystem. Akin to traditional financial systems, crypto markets have developed networks of complex interrelationships between infrastructures, intermediaries and market participants. As an example, the events of the so-called “Crypto Winter” of 2022-2023, which began in early 2022 with the crash of sister tokens USDTerra and Luna and resulted in a series of cascading failures and collapses including that of the major crypto conglomerate FTX, underscore the significant potential that interconnection, interdependencies, concentration and contagion have in the evolving ecosystem. Compared to traditional finance, which is underpinned by a wide range of regulatory and supervisory interventions of central banks and other international and domestic regulatory bodies, the crypto ecosystem has until recently remained largely unregulated. This however is changing rapidly in major economies around the world and is expected to change as well in the United States, as crypto increasingly becomes a regulated industry.
The crypto ecosystem is typically described as and characterized by decentralization and disintermediation. We have seen a range of situations however where the system does not operate in this way......

Abstract: The probability that an event will avalanche into an impairment of essential services constitutes a “systemic risk.” Owing to the inherent complexities of modern societies, the outbreak of a novel disease or the failure of a financial institution can rapidly escalate into an impact significantly larger than the initial event. Through the lens of complex system theory, this article draws a parallel between financial crises and disasters to contend that the regulatory framework for financial systemic risk is unequipped to address its fundamental dynamics. Epitomized by the market failure rationale, financial regulation is premised on a reductionist view that purports both systemic risk and law as external to the actions of market participants. Conversely, this article advances a twofold conceptual framework. First, it shows that systemic risk emerges from the same complex dynamics that generate the financial system. Second, it understands law as an agent of complexity, thus contributing to the emergence of finance and its inherent instability. Normatively, this conceptual framework reveals the limits of current regulatory approaches and constructs a holistic risk governance framework that is akin to the one adopted to govern disaster risks.
