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.

Replacing LIBOR

Publication of LIBOR―the London Interbank Offered Rate―will likely cease at the end of 2021. This is the message U.K. Financial Conduct Authority (FCA) CEO Andrew Bailey sent in 2017 when he announced that, after 2021, the FCA would no longer compel reluctant banks to respond to the LIBOR survey. Given the small number of underlying LIBOR transactions, and the reputational and legal risks banks face when submitting survey responses based largely on their expert judgement, we expect that most banks will then happily retreat. In just over two years, then, the FCA could declare LIBOR rates “unrepresentative” of financial reality and it will vanish (see, for example, here).

Most financial experts know this. Yet, LIBOR remains by far the most important global benchmark interest rate, forming the basis for an estimated $400 trillion of contracts (as of mid-2018; see Schrimpf and Sushko), about one-half of which are denominated in U.S. dollars (as of end-2016; see Table 1 here). While the use of alternative reference rates is increasing rapidly, to beat the LIBOR-countdown clock, the pace will have to quicken substantially. In the United States, the outstanding notional value of derivatives linked to the alternative secured overnight reference rate (SOFR) jumped from less than $100 billion to more than $9 trillion in just the past year (see SIFMA primer). Yet, this amount still represents a small fraction of outstanding dollar-LIBOR-linked instruments.

In this post, we examine the U.S. dollar LIBOR transition process, highlighting both the substantial progress and the major obstacles that still lie ahead. The key goal of the transition is to ensure that the inevitable cessation of LIBOR does not trigger system-wide disruptions. Unfortunately, at this stage, count us among those that remain deeply concerned….

Stress Testing Financial Networks: The Case of CCPs

Following the crisis of 2007-09, in which AIG’s bilateral derivatives trades played a notable role, the G20 leaders called for central clearing of standardized derivatives. The resulting shift has been dramatic: central counterparties (CCPs) now clear about three-fourths of interest rate contracts, up from less than one-fourth a decade earlier (see Faruqui, Huang and Takáts).

By substituting a CCP as the buyer to every seller and the seller to every buyer, central clearing mutualizes and can—with appropriate margining, trade compression, position liquidation procedures, and reporting—reduce counterparty risk (see Tuckman). CCPs also contribute to financial resilience by promoting uniform margin standards, reducing collateral and liquidity needs, and making risk concentrations (like that of AIG in the run-up to the crisis) more transparent.

At the same time, the shift to central clearing has concentrated risk in the CCPs themselves. Reflecting economies of scale and scope, as well as network externalities, a few CCPs serving global clearing needs have grown enormous. For example, as of the last report at end-September 2018, open interest at LCH Clearnet exceeded $250 trillion. Moreover, the clearing activity of some CCPs lacks any short-run substitute. As a result, to avoid disrupting large swathes of the global financial system, any recovery or resolution plan for these CCPs must ensure continuity of service (see CCP Resolution Working Group presentation to the OFR Financial Research Advisory Committee). Finally, CCPs are the most interconnected intermediaries on the planet, making them channels for transmission and amplification of financial distress within and across jurisdictions. As then-Governor Powell clearly states in the opening quote, the safety of CCPs is central to the resilience of the global financial system.

We and Richard Berner have been studying how regulators use stress tests (see our earlier posts here and here) to assess the resilience of financial networks, including banks and nonbanks. In our joint work, we focus on CCPs due to their centrality, their extreme interconnectedness and their lack of substitutability. This post is based on our research….

Making Unelected Power Legitimate

Through what administrative means should a democratic society in an advanced economy implement regulation? In practice, democratic governments opt for a variety of solutions to this challenge. Historically, these approaches earned their legitimacy by allocating power to elected officials who make the laws or directly oversee their agents.

Increasingly, however, governments have chosen to implement policy through agencies with varying degrees of independence from both the legislature and the executive. Under what circumstances does it make sense in a democracy to delegate powers to the unelected officials of independent agencies (IA) who are shielded from political influence? How should those powers be allocated to ensure both legitimacy and sustainability?

These are the critical issues that Paul Tucker addresses in his ambitious and broad-ranging book, Unelected Power. In addition to suggesting areas where delegation has gone too far, Tucker highlights others—such as the maintenance of financial resilience (FR)—where agencies may be insufficiently shielded from political influence to ensure effective governance. His analysis raises important questions about the regulatory framework in the United States.

In this post, we discuss Tucker’s principles for delegating authority to an IA. A key premise—that we share with Tucker—is that better governance can help substitute where simple policy rules are insufficient for optimal decisions….

Treasury Round II: The Capital Markets Report

Earlier this month, the U.S. Treasury published the second of four planned reports designed to implement the core principles for regulating the U.S. financial system announced in President Trump’s February 2017 Executive Order. This report focuses on capital markets. We wrote about the first report—regarding depository institutions—in June (see here). Future reports are slated to address “the asset management and insurance industries, and retail and institutional investment products and vehicles” and “nonbank financial institutions, financial technology, and financial innovation.”

A central motivation for all this work is to review the extensive regulatory reforms enacted in the aftermath of the 2007-09 financial crisis. President Trump’s stated principles provide an attractive basis for evaluating the effectiveness of Dodd-Frank in making the financial system both more cost-effective and safer. Where have the reforms gone too far? Where have they not gone far enough?

Much of the capital markets report focuses on ways to reduce the regulatory burden, and many of the proposals—which address issues ranging from initial public offerings (IPOs) to securitizations to financial market utilities (FMUs)—could improve market function. However, while they would involve a large number of changes—most of which can be implemented without new legislation (see table)—none of the 100-plus recommendations seem terribly dramatic, nor are they likely to have much impact on the goal of promoting economic growth.

Our overall reaction is that Treasury’s predispositions—which were more clearly evident in the earlier report—encourage doubts. To us, the numerous proposals look lopsided in favor of providing “regulatory relief” even where systemic concerns may persist....
