TradFi and DeFI: Same Problems, Different Solutions

In our recent primer on Crypto-assets and Decentralized Finance (DeFi), we explained that, so long as crypto-assets remain confined to their own world, they pose little if any threat to the traditional finance (TradFi) system. Yet, some crypto-assets are being used to facilitate transactions, as collateral for loans, as the denomination for mortgages, as a basis for ri s k-sharing, and as assets in retirement plans. Moreover, many financial and nonfinancial businesses are seeking ways to expand the uses of these new instruments. So, it is easy to imagine how the crypto/DeFi world could infect the traditional financial system, diminishing its ability to support real economic activity.

In this post, we highlight how the key problems facing TradFi (ranging from fraud and abuse to runs, panics, and operational failure) also plague the crypto/DeFi world. We also examine the different ways in which TradFi and crypto/DeFi address these common challenges.

To summarize our conclusions, while the solutions employed in TradFi are often inadequate and incomplete, features such as counterparty identification and centralized verification make them both more complete and more effective than those currently in place in the world of crypto/DeFi. Ironically, addressing the severe deficiencies in the current crypto/DeFi infrastructure may prove difficult without making highly unpopular changes that make it look more like TradFi—like requiring participants to verify their identity (see, for example, Makarov and Schoar and Crenshaw).

This is the second in our series of posts on crypto-assets and DeFi. In the next one, we will examine regulatory approaches to limit the risks posed by crypto/DeFi while supporting the benefits of financial innovation….

Comments on Fed CBDC Paper

Last month, the Federal Reserve issued a long-awaited discussion paper on the possibility of introducing a central bank digital currency (CBDC) for retail use. The Fed paper calls for comments on the benefits and risk of introducing a U.S. CBDC, as well as on its optimal design. In this post, we respond to each of the 22 questions posed in the discussion paper. For the most part, these responses are based on our previous analyses of CBDC (here and here).

At the outset, we highlight our doubt that the benefits of a U.S. CBDC will exceed the risks. In our view, other, less risky, means are available to achieve all the key benefits that CBDC advocates anticipate. Moreover, we are not aware of sustainable design features that would reduce the risks of financial instability that many analysts agree will accompany the introduction of a digital U.S. dollar.

However, this overall judgment regarding a CBDC’s benefits and risks is sensitive to two considerations that appear in the Fed’s analysis either explicitly or implicitly. First, CBDC may be a less risky alternative to stablecoins, should regulation of the latter prove politically infeasible (see our earlier post). Second, if other highly trustworthy financial jurisdictions (with convertible currencies, credible property rights protections, and free cross-border flow of capital) offer their own CBDC, the case for a U.S. CBDC—as a device to sustain widespread use of the dollar—would become stronger.

Against this background, we applaud the Fed’s conservative approach. Most important, the U.S. authorities are not rushing to act. Instead, they are thinking carefully about the design elements, are actively engaged in public outreach, and have committed not to proceed without first securing broad public support….

Big Tech, Fintech, and the Future of Credit

Lenders want to know that borrowers will pay them back. That means assessing creditworthiness before making a loan and then monitoring borrowers to ensure timely payment in full. Lenders have three principal tools for raising the likelihood of that firms will repay. First, they look for borrowers with a sufficiently large personal stake in their enterprise. Second, they look for firms with collateral that lenders can seize in the event of a default. Third, they obtain information on the firm’s current balance sheet, its historical revenue and profits, experience with past loans, and the like.

Unfortunately, this conventional approach to overcoming the challenges of asymmetric information is less effective for new firms that have both very short credit histories and very little in the way of physical collateral. As a result, these potential borrowers have trouble obtaining funds through standard channels. This is one reason that governments subsidize small business lending, and why entrepreneurs are forced to pledge their homes as collateral.

Well, new solutions have emerged to overcome this old problem. In this post we discuss how technology is increasing small firms’ access to credit. By using massive amounts of data to improve credit assessments, as well as real-time information and platform advantages to enforce repayment terms, technology companies appear to be doing what traditional lenders have not: making loans to millions of small businesses at attractive rates and experiencing remarkably low default rates.

The biggest advances are in places where financial systems are not meeting social needs….

To RMB or not to RMB? Lessons from Currency History

China is the world’s largest trader and (on a purchasing power parity basis) is about to surpass the United States as the world’s largest economy. China already accounts for about 10% of global trade in goods and services, and over 15% of global economic activity.

So, as China takes its place as the biggest economy on the globe, will its currency, the renminbi (RMB), become the most widely used international currency as well? Will the RMB supplant the U.S. dollar as the leading reserve currency held by central bankers and others, or as the safe-haven currency in financial crises?
