On September 17, the overnight Treasury repurchase agreement (repo) rate spiked to 6%—up from just 2.2% a week earlier and the highest level in more than 15 years (see DTCC GCF repo index). Oddly, this turmoil occurred at a time when the Fed had begun lowering its policy rate for the first time in more than a decade and market participants anticipated further policy easing ahead.

What led to this sudden disruption in short-term funding markets that been relatively calm in recent years? Had the Fed lost control? In our view, the explanation for the sudden rise in overnight interest rates is straightforward: the shrinkage of the Federal Reserve’s balance sheet that began in October 2017 reduced the aggregate supply of reserves gradually to where banks’ demand for reserves was insensitive to interest rates. Consequently, large temporary fluctuations in the supply of reserves that would have had virtually no impact even a few months ago, triggered sizable upward interest rate fluctuations.

Consistent with this view, the Federal Reserve recently took action to prevent a recurrence of the September disorder. At an unscheduled video conference meeting on October 11, the FOMC agreed to additional regular purchases of Treasury bills at least into the second quarter of 2020. The goal of this balance sheet expansion is to maintain reserve balances at least as high as their level in early-September before the turmoil began.

In the remainder of this post, we discuss the evolution of the supply and demand for reserves in recent years. We argue that, because no one—including the Fed—knew the precise level of reserves at which the demand curve would become inelastic, an episode like the one on September 17 was virtually inescapable as reserve supply declined. If our diagnosis of the cause is correct, then recent actions should help put the issue to rest. Yet, given the inevitability of the event―that the day would come when shrinking reserve supply hit the inelastic part of the reserve demand curve―the Fed could (and should) have been prepared. If so, it could have avoided even a temporary dent in its well-deserved reputation for operational prowess….

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….

Alternative Reference Rates: Meeting the Challenges

Guest post by Richard Berner, Executive-in-Residence (Center for Global Economy and Business) and Adjunct Professor, NYU Stern School of Business

In response to the fragility of LIBOR and other interest-rate benchmarks, regulators globally are working with industry to identify sturdy alternatives. Despite significant progress, concerns persist that the transition to these new reference rates will be disruptive.

While these concerns are legitimate (see Eclipsing LIBOR), both U.S. and global authorities and market participants have begun to address them in ways that should go a long way to managing the risks. In this post, we review why LIBOR’s persistent fragility makes reform critical, and examine progress on some of the ongoing reforms....

Eclipsing LIBOR

The manipulation of the London Interbank Offered Rate (LIBOR) began more than a decade ago. Employees of leading global firms submitted false reports to the British Banking Association (BBA), first to influence the value of LIBOR-linked derivatives, and later (during the financial crisis) to conceal the deterioration of their employers’ creditworthiness. U.S. and European regulators reported many of the details in 2012 when they fined Barclays, the first of a dozen financial firms that collectively paid fines exceeding $9 billion (see here). In addition to settling claims of aggrieved clients, these firms face enduring reputational damage: in some cases, management was forced out; in others, individuals received jail terms for their wrongdoing.

You might think that in light of this costly scandal, and the resulting challenges in maintaining LIBOR, market participants and regulators would have quickly replaced LIBOR with a sustainable short-term interest rate benchmark that had little risk of manipulation. You’d be wrong: the current administrator (ICE Benchmark Administration), which replaced the BBA in 2014, estimates that this guide (now called ICE LIBOR) continues to serve as the reference interest rate for “an estimated $350 trillion of outstanding contracts in maturities ranging from overnight to more than 30 years [our emphasis].” In short, LIBOR is still the world’s leading benchmark for short-term interest rates.

Against this background, U.K. Financial Conduct Authority CEO Andrew Bailey, recently called for a transition away from LIBOR before 2022 (see here). In this post, we briefly explain LIBOR’s role, why it remains an undesirable and unsustainable interest rate benchmark, and why it will be so difficult to replace (even gradually over several years) without risking disruption.
