Reforming the Federal Home Loan Bank System

We authored this post jointly with our friend and colleague, Lawrence J. White, Robert Kavesh Professor of Economics at the NYU Stern School of Business.

Some government financial institutions strengthen the system; others do not. In the United States, as the lender of last resort (LOLR), the Federal Reserve plays a critical role in stabilizing the financial system. Unfortunately, their LOLR job is made harder by the presence of the Federal Home Loan Bank (FHLB) system—a government-sponsored enterprise (GSE) that acts as a lender of next-to-last resort, keeping failing institutions alive and increasing the ultimate costs of their resolution.

We saw this dangerous pattern clearly over the past year when loans (“advances”) from Federal Home Loan Banks (FHLBs) helped postpone the inevitable regulatory reckoning for Silicon Valley Bank (SVB), Signature Bank, and First Republic Bank (see Cecchetti, Schoenholtz and White, Chapter 9 in Acharya et. al. SVB and Beyond: The Banking Stress of 2023).

From a public policy perspective, FHLB advances have extremely undesirable properties. First, in addition to being overcollateralized, these loans are senior to other claims on the borrowing banks—including those of the Federal Deposit Insurance Corporation (FDIC) and the Federal Reserve: If the borrower defaults, the FHLB lender has a “super-lien.” Second, there is little timely disclosure about the identity of the borrowers or the amount that they borrow. Third, they are willing to provide speedy, low-cost funding to failing institutions—something we assume private lenders would not do.

In this post, we make specific proposals to scale back the FHLB System’s ability to serve as a lender to stressed banks….

Making Banking Safe

The regulatory reforms that followed the financial crisis of 2007-09 created a financial system that is far more resilient than the one we had 15 years ago. Today, banks and some nonbanks face more rigorous capital and liquidity requirements. Improved collateral rules for market-making activities can dampen shocks. And, some institutions are subject to well-structured resolution regimes.

Yet, the events of March 2023 make clear that the system remains fragile. The progress thus far is simply not enough. What else needs to be done?

In a new essay, we address this critical question. Our assessment of the banking system turmoil of 2023 leads us to several obvious conclusions, some of which clearly escaped both bank managers and their supervisors. Perhaps the simplest and most significant is that banks can survive either risky assets or volatile funding, but not both. Another is that supervisors are willing to treat some banks as systemic in death, but not in life.

We also draw two compelling lessons from the recent supervisory and resolution debacles. First, a financial system which relies heavily on supervisory discretion is unlikely to prove resilient. Second, authorities with emergency powers to bail out intermediaries during a panic will always do so. That is, policymakers are incapable of making credible commitments to impose losses on depositors and others. In our view, the only way to address this commitment problem is to prevent crises….

Central Banks' New Frontier: Interventions in Securities Markets

In his 2016 book The End of Alchemy, our friend and former Bank of England Governor Mervyn King provided a template for financial reform aimed at reducing the frequency and severity of crises. At the time, we were very cautious for two reasons. First, we believed that adoption of King’s framework would vastly increase the influence of central banks on private financial markets, something that could ultimately lead to a misallocation of resources in the economy and to a diminution of the independence of monetary policy that is necessary for securing price stability. Second, we doubted that most central banks had the technical capacity to implement the proposal.

Well, the landscape has changed significantly. During the pandemic, central banks intervened massively in private securities markets and there now appears to be no turning back. In a number of jurisdictions, monetary policymakers broadened the scale and scope of their lending and intervened directly in financial markets, going significantly beyond even their extraordinary actions during the 2007-09 financial crisis. As a result, we likely will be paying the costs that we feared could accompany the implementation of King’s proposal, so we might as well reap the benefits.

In this post, we discuss central banks’ pandemic interventions and the type of infrastructure needed to support them. We then review King’s proposal, highlighting how adopting his approach would make the financial system safer, while radically simplifying the role of regulators and supervisors ….

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….

Russian Sanctions: Questions and Answers

This post is authored jointly with our friend and colleague, Professor Richard Berner, Co-Director of the NYU Stern Volatility and Risk Institute.

Russia’s invasion of Ukraine is altering global security and economic relationships. In this post, we focus on the financial and trade sanctions imposed on Russia. These sanctions are the most powerful and costly punishments imposed on a major economy at least since the Cold War. Their speed, breadth and coordinated global support appear unprecedented.

Not surprisingly, the impact is immediately visible. The damage to the Russian economy and financial system includes, but is not limited to, a plunge of the ruble (by about 40 percent versus the dollar over the past month amid heightened volatility); runs on domestic banks; a sharp hike in the central bank’s policy rate; imposition of capital controls; shutdown of the Russian stock market; collapse in the value of Russian companies traded on foreign stock exchanges; removal of Russian equities from global indexes; and the collapse of Russia’s sovereign credit rating to junk status.

The purpose of this post is to pose and provisionally answer a series of questions raised by this new sanctions regime.…

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….

Same Function, Same Risks, Same Regulation

Technological progress always brings new challenges for financial regulators. While some innovations today seem revolutionary, in many cases they are not. What is new is the pace and breadth of innovation associated with fintech. Taking advantage of recent advances in information technology and communication, entrepreneurs and incumbent financial firms are creating a wide array of new intermediaries.

At a conceptual level, regulators’ approach to the risks created by these new entrants would seem to be straightforward: any provider of the same financial service, creating the same risks, should face the same regulation. Encourage innovation, but guard against any harm that it poses to the financial system.

How might we do this? Again, the answer is clear: focus on the financial activities, functions and services themselves (even though rule enforcement will almost surely proceed through the firms, entities or institutions that provide the services). Such activity-focused regulation requires an enormous shift of our approach. With our regulatory objectives in mind, we need to enumerate the financial activities and then create a framework that matches these two lists. In this post, we outline how regulators can begin to approach this task….

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.

U.S. Gets a Start on Climate-related Financial Risk

Co-authored with Richard Berner, NYU Stern Clinical Professor of Finance and Co-Director, Volatility and Risk Institute.

Many sources of risk threaten the U.S. financial system. Pandemic risk and cyber risk are at or near the top of our list of nightmares. Yet, with the UN Climate Change conference (COP26) under way in Glasgow, attention is shifting to efforts aimed at limiting the economic and financial damage from climate change, including a timely new “Report on Climate-relat ed Financial Risk” from the U.S. Financial Stability Oversight Council (FSOC).

As the Report makes clear, U.S. policymakers need a far better understanding of climate-related financial risk. Indeed, when President Biden issued an exec utiv e order in May instructing financial regulators to conduct a thorough risk assessment, the United States already was behind other advanced economies. As an initial response to the President’s directive, the Report catalogs the range of climate risk threats, describes actions individual U.S. regulators have begun taking to address them, and lists many things that still need to be done. By setting priorities, the FSOC is now putting climate change “squarely at the forefront of the agenda of its member agencies.”

In this post, we highlight three themes in the Report: (1) the ongoing rise of physical climate risk; (2) the conceptual challenges associated with measurement, as well as the data gaps; and (3) the benefits of scenario analysis as a tool for assessing the financial stability risks arising from climate change. The key lesson that we draw from scenario analysis is that a financial system resilient to a range of other shocks is more likely to be resilient against climate risk. Put differently, a less-resilient financial system is vulnerable to all types of shocks, including those arising from climate change.

Central Banks and Climate Policy

Avoiding a climate catastrophe requires an urgent global effort on the part of households, firms and governments to reduce our reliance on fossil fuels. Like many economists, we support a carbon tax. We also favor generous fiscal support for R&D to substitute for fossil fuels and remove carbon from the atmosphere.

What role should central banks play in this global effort? That is the prime focus of this post. We argue that central banks must preserve the independence needed for effective monetary policy. That implies only a modest role in addressing climate change.

Central banks are involved in both financial regulation and monetary policy. In each case, there are some things that central bankers can and should do to help counter the threat posed by climate change. As financial regulators, they should implement an improved disclosure regime and develop tools to ensure the financial system is resilient to climate risks.

In conducting monetary policy, central bankers should follow a simple, powerful principle: do not influence relative prices. To be sure, it is and should be standard practice to use interest rates to influence relative prices between consumption today and tomorrow. However, central banks ought not influence relative prices among contemporaneous activities. We will see that achieving this form of relative price neutrality may require central bankers to shift the composition of their assets and to alter the treatment of collateral in their lending operations….
