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 risk-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….

Stablecoin: The Regulation Debate

Last month, the President’s Working Group on Financial Markets (PWG) called for the introduction of a regulatory framework for “payment stablecoins”—private crypto-assets that (unlike the highly volatile Bitcoin) are pegged 1:1 to a national currency and “have the potential to be used as a widespread means of payment.” Most notably, to limit the risk of runs, the Report calls for legislation restricting stablecoin issuance to insured depositories.

In this post, we first document the rapid growth of stablecoin usage. We then highlight the features which make stablecoins subject to run risk that, in the absence of appropriate governmental controls, could destabilize the financial system. Next, we consider the three regulatory approaches that Gorton and Zhang (GZ) propose for making stablecoins resilient: the first, and the one favored by the PWG, is to limit stablecoin issuance to insured depositories; the second is to require 1:1 backing of stablecoins with sovereign securities (in the case of the United States and the U.S. dollar, these would be U.S. Treasury issues); and the third is to require 1:1 backing with central bank reserves. We conclude with a brief discussion of whether central bank digital currencies are an appropriate means to displace stablecoins.

To foreshadow our conclusions, we view the PWG proposal as the preferred alternative. However, absent near-term prospects for legislative action, we hope that the Financial Stability Oversight Council (FSOC) will consider—as GZ suggest—using its powers under the Dodd-Frank Act to designate the issuance of payments stablecoins as an activity that is “likely to become” systemically important. FSOC designation would authorize the Federal Reserve to promote uniform standards without waiting years for legislation that authorizes a new regulatory framework.

Libra's dramatic call to regulatory action

Facebook’s June 18 announcement that it has created a Geneva-based entity with plans to issue a currency called Libra is sending shock waves through the financial world. The stated objectives of creating Libra are to improve the efficiency of payments and to ease financial access. While these are laudable goals, it is essential that we achieve them without facilitating criminal exploitation of the payments system or reducing the ability of authorities to monitor and mitigate systemic risk. In addition, any broad-based financial innovation should ease the stabilization of consumption.

On all of these criteria, we see Libra as doing more harm than good. And, for the countries whose currencies are excluded from the Libra portfolio, it will diminish seignorage, while enabling capital outflows and, in periods of stress, accelerating capital flight.

Like Bank of England Governor Carney, we have an open mind, and believe that increased competition, coupled with the introduction of new technologies, will eventually lower stubbornly high transactions costs, improving the quality of financial services globally. But in this case, we urge a closed door….
