Decentralized Finance (DeFi): Transformative Potential and Associated Risks
Financial services in the crypto finance world are provided by a combination of centralized finance (CeFi) organizations and decentralized finance (DeFi). CeFi's are roughly similar to traditional financial intermediaries, but DeFi seeks to provide services using smart contracts (computer code) rather than an intermediary. DeFi's unusual structure creates some interesting potential but also raises new risks in addition to those already inherent in blockchains and crypto finance. This paper reviews some of the opportunities and risks.

The Origins of Market Power in DeFi
In our previous Liberty Street Economics post, we introduced the decentralized finance (DeFi) intermediation chain and explained how various players have emerged as key intermediaries in the Ethereum ecosystem. In this post, we summarize the empirical results in our new Staff Report that explains how the need for transaction privacy across the DeFi intermediation chain gives rise to intermediaries’ market power.

Natural Centralization in Decentralized Finance
Can centralization arise absent barriers to entry? We confront this question by studying the Ethereum blockchain, a market featuring permissionless entry, standardized protocols, and a transparent public ledger. We show that natural centralization emerges when information asymmetry confronts risk-sharing. Using a novel dataset distinguishing private from public order flow, we find that a 1 percent increase in the value of private information causally increases an intermediary’s profit share by 0.57 percent. We use a dynamic bargaining model to illustrate that intermediaries leverage private ...

Can Decentralized Finance Provide More Protection for Crypto Investors?
Several centralized crypto entities failed in 2022, resulting in the cascading failure of other crypto firms and raising questions about the protection of crypto investors. While the total amount invested in the crypto sector remains small in the United States, more than 10 percent of all Americans are invested in cryptocurrencies. In this post, we examine whether migrating crypto activities from centralized platforms to decentralized finance (DeFi) protocols might afford investors better protection, especially in the absence of regulatory changes. We argue that while DeFi provides some ...

The Blockchain Revolution: Decoding Digital Currencies
Cryptocurrencies and decentralized finance have grown considerably since the publication of the white paper on bitcoin in 2009. This article presents an overview of cryptocurrencies, blockchain technology, and their applications, explaining the spirit of the enterprise and how it compares with traditional operations. We discuss money, digital money, and payments; cryptocurrencies, blockchain, and the double-spending problem of digital money; decentralized finance; and central bank digital currency.

Tokenization: Overview and Financial Stability Implications
In this paper we outline tokenization, which is a new and rapidly growing financial innovation in crypto asset markets, and we discuss potential benefits and financial stability implications. Tokenization refers to the process of constructing digital representations (crypto tokens) for non-crypto assets (reference assets). As we discuss below, tokenizations create interconnections between the digital asset ecosystem and the traditional financial system. At sufficient scale, tokenized assets could transmit volatility from crypto asset markets to the markets for the crypto token's reference ...

Composable Finance
Composability—open interactions between assets and protocols—facilitates a modular financial architecture. I document the emergence of composed asset transformation, where tokenized assets are re-bundled to alter access, liquidity, and risk characteristics to broaden and enhance the set of tokenized U.S. dollar instruments. Yet, I argue that “naive” composability fundamentally conflicts with the provision of pooled arrangements needed for liquidity provision, risk-sharing, and capital backstops. I demonstrate this in an economy consisting of a vertical chain of protocols. Upper-layer ...
