Bank of Canada Analyzes DeFi Innovations and Challenges

The Bank of Canada released a staff note on decentralized finance (DeFi) on October 17, offering an evaluation of the innovations that have propelled its popularity and an assessment of the associated challenges and risks.

DeFi is described in the note as a multi-layered structure, with the Ethereum blockchain serving as its foundational layer, often referred to as the settlement layer. On top of this primary blockchain, developers build a variety of tools and services, including tokenization, lending and borrowing services, and more. The staff note detailed how the DeFi ecosystem gained prominence, particularly in 2020, becoming an integral part of the cryptocurrency economy, with transactions worth billions in the following years. However, the popularity of DeFi declined in 2022, largely due to the collapse of several key crypto platforms with substantial exposure to DeFi, such as Terra.

The staff note emphasized several key features of the decentralized ecosystem. Notably, it praised DeFi’s “composability,” which enables various apps and services within the ecosystem to seamlessly interact. The Bank of Canada’s note outlined three key areas where DeFi can potentially transform the financial system:

  • Frictionless financial service offering: DeFi, based on a decentralized ledger system, reduces the frictions inherent in the traditional financial system, broadening the range of financial services available.
  • Open competition: DeFi’s open-source nature allows anyone to participate in its development and access its services, fostering increased competition and offering improved options for end users.
  • Transparency: DeFi’s use of programmable smart contracts eliminates intermediaries and enhances transparency, as all transaction data is accessible to those who wish to analyze it.

However, the staff note also highlighted the challenges and risks associated with the DeFi ecosystem, concluding that “despite its innovations and possibilities, the overall economic benefits of DeFi remain limited.” The note identified three key challenges: Lack of real-world tokenization, Higher concentration of interconnection within the DeFi ecosystem, and Dependence on an unregulated centralized finance ecosystem.

Additionally, the note addressed the regulatory challenges posed by the DeFi ecosystem and the increasing vulnerabilities leading to various hacks and exploits. It pointed out that the “anonymous and borderless nature of public blockchains complicates regulatory oversight.”
