This week, we saw new heights of turbulence in the tempestuous crypto world. Market capitalization plunged as the loss of confidence in a popular coin—designed to be pegged to the dollar—triggered a run that fueled widespread contagion. At this writing, the estimated value of all crypto assets stands at $1.1 trillion, down nearly 60 percent from the $2.7 trillion peak in early November. What are the broader implications for the crypto world and the traditional financial system? Do we face the prospect of the famously volatile world of crypto-assets and decentralized finance (DeFi) undermining the stability of traditional financial (TradFi) system and the real economy?

So long as all these crypto-assets remain confined to the DeFi world, they pose no threat to TradFi or to economic activity. In practice, the fact that enormous fluctuations in value are met with a global shrug (at least so far) is prima facie evidence that crypto-assets currently are systemically irrelevant.

But will crypto-assets remain so disconnected from TradFi and from real economic activity? Crypto instruments already are escaping the DeFi metaverse in notable ways. These include the use of crypto-assets as a means of payment (see our earlier post on stablecoins), as collateral for loans and mortgages, and as assets in retirement plans. These developments lead us to ask two related questions: First, how will the risks arising from crypto and DeFi evolve? Second, how will regulators deal with them if and when they do?

This post is the first in a series that aims to address these questions. As befits a primer, we start with the basics: characterizing crypto-assets and DeFi. In the process, we define common terms and highlight analogies between DeFi and TradFi (traditional finance). For readers who would like to go deeper, we link to a range of studies that provide useful background information.

In a future post, we will highlight that the problems which frequently arise in TradFi (ranging from fraud and abuse to runs, panics, and operational failure) also appear in DeFi, while the aim of DeFi to avoid any discretionary intervention renders key TradFi corrective tools (such as the court adjudication of incomplete contracts) inoperable. Eventually, we also will post about regulatory approaches that can address the risks posed by DeFi, while supporting responsible financial innovation that lowers transaction costs and broadens consumer choice….
