The concept of the "Finternet"—a vision for the future of global finance—has been gaining traction in financial circles. This vision was introduced in April 2024 through a paper titled "Finternet: The Financial System for the Future," published by the Bank for International Settlements (BIS) co-authored by Agustín Carstens and Nandan Nilekani. The paper provides a template for balancing regulation and innovation and explores how technologies could transform financial services. By incorporating these innovations within a strong regulatory framework, the Finternet aims to expand access, enhance personalization, and improve the efficiency and security of transactions, all while reducing costs for users. 

The Finternet Vision

At its core, the Finternet concept centers on users—both individuals and businesses—placing them at the heart of their financial ecosystem. It further envisions a network of interconnected financial ecosystems leveraging cutting-edge technology to provide seamless, efficient, and inclusive financial services. This vision resonates strongly with ideas proposed by Lawrence Lessig in his influential work “Code: And Other Laws of Cyberspace.” Lessig argued that “code is law” in digital environments, meaning that the architecture of digital systems can be as influential as traditional legal structures in shaping behavior. The Finternet builds on this concept by proposing a financial system where regulatory compliance, user protections, and identity management are embedded directly into the technological infrastructure.

Key Components of the Finternet Vision

A key aspect of the Finternet vision is that most of the necessary technology is already in place and progressing rapidly. 

1. Unified Ledgers: Digital platforms that consolidate multiple financial assets, enabling fast and secure transactions without complex intermediaries.

2. Tokenization: The representation of various assets digitally as tokens for more efficient trading and management.

3. Interoperability: Ensuring different financial systems can work together seamlessly.

4. Enhanced Security and Privacy: Leveraging advanced technologies like cryptography,  distributed ledgers, Zero-Knowledge Proofs (ZKP), and Multi-Party Computation (MPC) to ensure both security and privacy in financial transactions.

5. Inclusivity: Expanding access to financial services, especially in emerging markets and developing economies.

Self-Sovereign Identity

A crucial element of the Finternet vision is the integration of self-sovereign identity (SSI). SSI is a model that gives individuals control over their digital identities without relying on centralized authorities. In the context of the Finternet, SSI could revolutionize interactions with financial services by:

1. User Control: Allowing individuals complete control over their personal information, deciding what to share and with whom.

2. Privacy by Design: Enabling selective disclosure, where users can prove specific attributes (like age or credit score) without revealing unnecessary personal details.

3. Portable Identity: Allowing users to carry their verifiabke credentials across different financial platforms and services, streamlining onboarding processes.

4. Reduced Fraud: Utilizing cryptographic proofs to significantly reduce identity theft and fraudulent activities in the financial sector.

5. Global Accessibility: Providing a pathway to financial services for the unbanked, who often lack traditional forms of identification.

Potential Benefits

The implementation of the Finternet, powered by SSI, promises numerous benefits:

1. Faster Transactions: Near-instantaneous settlement of financial transactions.

2. Lower Costs: Streamlined processes that reduce the need for intermediaries.

3. Increased Access: Expanding financial services to underserved populations.

4. Innovation: Spurring the development of new, user-centric financial products and services.

5. Improved Compliance: Simplifying KYC (Know Your Customer) and AML (Anti-Money Laundering) processes while maintaining high standards.

6. Enhanced Privacy: Giving users granular control over their personal and financial data.

Challenges and Considerations

While the Finternet vision is compelling, several challenges remain, particularly when examined through the lens of Lessig’s four regulatory forces: law, architecture (code), market, and social norms.

1. Law (Regulation):

• Updating existing financial regulations to accommodate new technologies and identity models.
• Developing new legal frameworks for tokenized assets and self-sovereign identity.
• Ensuring compliance with the “safety and soundness” mandate for banks.
• Addressing cross-border legal and regulatory issues in a globally connected financial system.
  
  

2. Architecture (Code):

• Ensuring scalability, security, and interoperability of complex systems.
• Developing robust protocols for unified ledgers and tokenized assets.
• Implementing secure and privacy-preserving self-sovereign identity systems.
• Building fail-safe mechanisms and risk management tools into the core architecture.
  
  

3. Market:

• Creating economic incentives for the adoption of the Finternet by both institutions and individuals.
• Balancing innovation with stability in the financial sector.
• Addressing potential disruption to existing business models in banking and finance.
• Ensuring fair competition while maintaining the integrity of the financial system.
  
  

4. Social Norms:

• Shifting public perception and trust towards digital-first financial services.
• Educating users on managing their digital identities and financial data.
• Addressing privacy concerns and changing attitudes towards data sharing.
• Maintaining the expectation of bank stability and trustworthiness in a rapidly evolving system.
  
  

Cross-cutting challenges include governance, adoption, interoperability, and financial inclusion. Addressing these issues will require coordinated efforts from regulators, technologists, financial institutions, and society.

The Path Forward for US Banks

US regulators would need to get behind a framework for the Finternet that maintains or enhances the safety and soundness of the banking system. This framework might include more guidance on tokenized assets, SSI implementation, and interoperability standards, all designed to ensure the stability and reliability of the financial system. By endorsing such a framework, regulators can provide the necessary support and legitimacy for the Finternet’s development while preserving their crucial oversight role.

The Finternet could potentially democratize financial services in America, allowing smaller institutions and new entrants to compete more effectively with large banks. Americans might need to adapt to new ways of thinking about their financial identities and data. The concept of a bank account could evolve into a more holistic digital financial identity. At the same time, the longstanding expectation of bank stability and trustworthiness would need to be maintained and potentially reinforced in this new digital context.

Ultimately, the Finternet represents the future direction of global finance, with its emphasis on innovation, inclusivity, and user empowerment. To stay at the forefront of this transformation, the U.S. banking system should take a leadership role in shaping and implementing these advancements, ensuring it adapts to the changing landscape and sets the standards for the financial systems of tomorrow.
