The Federal Home Loan Banks: Two Lessons in Regulatory Arbitrage

There is an important U.S. government-sponsored banking system that most people know nothing about. Created by an act of Congress in 1932, the Federal Home Loan Banks (FHLBs) issue bonds that investors perceive as having government backing, and then use the proceeds to make loans to their members: namely, 6,800 commercial banks, credit unions, insurance companies and savings associations. As the name suggests, the mission of the (currently 11) regional, cooperatively owned FHLBs is “to support mortgage lending and related community investment.” But, since the system was founded, its role as an intermediary has changed dramatically.

With assets of roughly $1 trillion, it turns out that the FHLBs—which operate mostly out of the public eye—have been an important source of regulatory arbitrage twice over the past decade. In the first episode—the 2007-09 financial crisis—they partly supplanted the role of the Federal Reserve as the lender of last resort. In the second, the FHLBs became intermediaries between a class of lenders (money market mutual funds) and borrowers (banks), following regulatory changes designed in part to alter the original relationship between these lenders and borrowers. The FHLBs’ new role creates an implicit federal guarantee that increases taxpayers’ risk of loss.

In this post, we highlight these episodes of regulatory arbitrage as unforeseen consequences of a complex financial system and regulatory framework, in combination with the malleability and opaqueness of the FHLB system.…

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….

Improving resilience: banks and non-bank intermediaries

Debt causes fragility. When banks lack equity funding, even a small adverse shock can put the financial system at risk. Fire sales can undermine the supply of credit to healthy firms, precipitating a decline in economic activity. The failure of key institutions can threaten the payments system. Authorities naturally respond by increasing required levels of equity finance, ensuring that intermediaries can weather severe conditions without damaging others.

Readers of this blog know that we are strong supporters of higher capital requirements: if forced to pick a number, we might choose a leverage ratio requirement in the range of 15% of total exposure (see here), roughly twice recent levels for the largest U.S. banks. But as socially desirable as high levels of equity finance might be, the fact is that they are privately costly. As a result, rather than limit threats to the financial system, higher capital requirements for banks have the potential to shift risky activities beyond the regulatory perimeter into non-bank intermediaries (see, for example here).

Has the increase of capital requirements since the financial crisis pushed risk-taking beyond the regulated banking system? So far, the answer is no. However, in some jurisdictions, especially the United States, the framework for containing systemic risk arising from non-bank financial institutions remains inadequate….

Size is Overrated

This month, in the guise of supporting community banks, the U.S. Senate passed a bill (S.2155) that eases regulation of large banks. We share the critics’ views that this wide-ranging dilution of existing regulation will reduce the resilience of the U.S. financial system.

In its best known and most publicized feature, the Senate bill raises the asset size threshold that Dodd-Frank established for subjecting a bank to strict scrutiny (such as the imposition of stress tests, liquidity requirements, and resolution plans) from $50 billion to $250 billion. In this post, we examine the role of asset size in determining the systemic importance of a financial intermediary. It turns out that (aside from the very largest institutions, where it does in fact dominate) balance sheet size is not a terribly useful indicator of the vulnerability a bank creates. We conclude that Congress should ease the strict oversight burden on institutions that pose little threat to the financial system without raising the Dodd-Frank threshold dramatically.

Judge makes an elegant proposal for accomplishing this. For institutions with assets between $100 billion and $250 billion, Congress should just flip the default. Rather than obliging the Fed to prove a mid-sized bank’s riskiness, give the bank the opportunity to prove it is safe. This approach gives institutions the incentive to limit the systemic risk they create in ways that they can verify. It also sharply reduces the risk of litigation by banks that the Fed deems risky...

FSOC and Systemic Risk: Treasury's Report

In response to the financial crisis of 2007-2009, Congress created the Financial Stability Oversight Council (FSOC), a committee of the chiefs of the U.S. regulatory agencies, chaired by the Treasury Secretary, to monitor and secure the stability of the financial system. Critical to this task is the FSOC’s authority to designate nonbanks as “systemically important financial institutions” (SIFIs).

On November 17, the U.S. Treasury issued a report assessing the FSOC’s designation process. Treasury calls on the FSOC to adopt a strategy that prioritizes the regulation of activities or functions—affecting whole sectors of the financial industry—over regulation based on entity or legal form (such as the designation authority). For the most part, we find this sensible, as this focus reduces the scope for regulatory arbitrage that an entities-only approach may foster (see here).

However, we doubt that activities-based regulation alone will be sufficient to limit systemic risk. Our overall conclusion is that the Treasury’s approach sets the bar for FSOC designation too high, diminishing its deterrence effect on undesignated nonbanks. In the end, a sensible focus on both entities and activities is needed to fulfill one of FSOC’s key objectives—to restore market discipline. Adopting the Treasury’s proposed framework will not meet the goal, set out in the President’s Core Principles for Regulating the U.S. Financial system (see Executive Order 13772), of preventing taxpayer-funded bailouts....

Managing Risk and Complexity: Legal Entity Identifier

Prior to the financial crisis, even an informed observer might have naïvely believed that the CEOs of big financial firms could simply push a button to view the current exposure of their firms to any other firms in the world. Or, if less technologically advanced, they could call their chief risk officers or chief financial officers to obtain end-of-day positions.

Not even close. By the time that Lehman failed in September 2008, large financial holding companies had evolved into extremely complex structures with hundreds or thousands of subsidiaries for which the parent companies lacked consolidated information technology and risk-management systems. The multiplicity of information systems meant that different parts of the same firm employed varying names and codes to identify the same counterparty. Fixing this, merging all of the information structures and ensuring consistency, would have been an expensive proposition that managers (compensated out of current profits) had incentive to delay.

Correcting these deficiencies in the financial infrastructure is not a trivial matter. Simplifying the problem requires the creation of a unique, universal, and permanent identification system for both institutions (financial and nonfinancial) and instruments. Realizing the nature of the opportunity and the challenge, in November 2011, the G20 called for the creation of a global legal entity identifier (LEI). Importantly, everyone realized that given the massive size of the financial system that supports both domestic and cross-border activity, the solution had to be global. (For pioneering analyses, see work by the Federal Reserve and the Office of Financial Research. For up-to-date information on the LEI, see here.)....
