Reforming U.S. Dollar LIBOR: The Path Forward

Remarks by

September 4, 2014

Thank you for giving me this opportunity to speak this evening. I would like to
discuss ongoing efforts to reform the current structure and uses of the London Interbank
Offered Rate, commonly referred to as LIBOR. These reforms affect not only the
financial industry, but also a large number of U.S. households and corporations.
LIBOR is a reference rate. When two parties enter a financial contract in which
interest payments are to be exchanged, they frequently choose to base those payments on
LIBOR. LIBOR is currently referenced in roughly $300 trillion worth of contracts
globally, which means that it is part of the global financial system’s critical
infrastructure.1 But LIBOR’s credibility was badly undermined by the scandal that
erupted when some of the banks that help produce the rate attempted to manipulate it by
contributing inaccurate estimates of their borrowing costs. These illegal actions helped
damage the public’s trust not just in LIBOR, but also in financial markets and institutions
more broadly.
In response, a number of global efforts to reform reference rates have been
undertaken. LIBOR is produced and administered in London. As a result of the steps
taken by the government of the United Kingdom, LIBOR is now regulated and
supervised by the U.K. Financial Conduct Authority (FCA). The International
Organization of Securities Commissions (IOSCO) developed a broad set of 19 principles
that reference rates and other financial benchmarks are now expected to meet.2 Building
on this work, in July, the Financial Stability Board (FSB) released a report outlining a

-2number of further reform proposals.3 Continuing the work of my former Fed colleague
Jeremy Stein, I recently took over as co-chair--along with Martin Wheatley, chief
executive officer of the FCA--of the international group that drafted the report and is now
charged with implementing its recommendations.4 Today I will discuss the reasons why
further reforms are necessary and how those reforms should proceed, and I will focus on
U.S. dollar LIBOR.5 As is made clear in the FSB report, while the goals and principles
of the official sector participants are uniform, specific plans for reference rate reform will
vary by currency, depending on differences in markets and institutions.
I will share my conclusion at the outset. While there have been significant
reforms, much remains to be done.6 First, U.S. dollar LIBOR needs to be updated to
reflect current practices in unsecured funding markets and to be better anchored in actual
transactions. Second, and equally important, regulators need to work with market
participants to encourage them to develop and adopt alternative reference rates that better
reflect the current structure of U.S. financial markets, in which borrowing and derivatives
transactions are much more likely to be secured with collateral. Going forward, these
alternative rates could replace LIBOR as the reference rate for new interest rate
derivatives and some other contracts denominated in U.S. dollars. These dual transitions
will need to be managed very carefully to avoid disrupting the financing markets on
which borrowers and lenders depend. But I believe that they are crucial to strengthening
the stability of our financial system and to helping restore the public’s faith in its

-3integrity. This problem is not just Wall Street’s concern; every household with a LIBORlinked mortgage and every corporation with a LIBOR-linked loan has an interest in more
robust U.S. dollar reference rates.
The Basics
I will take a few moments to explain the basic mechanics of LIBOR for those who
have not spent time on an interest rate swap desk. For almost three decades, LIBOR was
run by the British Bankers’ Association. Just a few months ago, a private corporation
called ICE Benchmark Administration (IBA) took over the daily production and
administration of the rate subject to the regulation and supervision of the FCA. Today,
18 banks participate in the panel that contributes to the production of U.S. dollar LIBOR.
Each morning at 11 a.m. London time, those banks estimate the rate at which they could
borrow at several different maturities ranging from overnight up to a year, and they send
those estimates to IBA. It is often the case that banks have recent transactions at some
but not all of these maturities. Where there are no transactions, they submit estimates of
their borrowing costs based on their judgment. In addition to U.S. dollar LIBOR, the rate
is produced in four other currencies--the euro, the yen, the British pound, and the Swiss
franc--although not all banks contribute rates in all currencies. The administrator
provides specific instructions to the panel banks regarding their submissions; currently,
these instructions direct banks to reflect the perceived rate at which they could borrow
from another bank.7 The administrator collects these submissions and, after dropping the
highest and lowest quartiles at each maturity, publishes an average of the remaining
submissions as the U.S. dollar LIBOR rate for that day.

The actual question asks banks only about transactions of “reasonable market size.” This size is not
defined and is left to banks’ judgment.

-4Pervasive and Problematic
When the British Bankers’ Association standardized LIBOR in the 1980s for use
in interest rate products, I doubt that anyone could have imagined how pervasive it would
eventually become. As I mentioned, there are an estimated $300 trillion in LIBOR
contracts, roughly half which reference dollar LIBOR. In the United States, dollar
LIBOR is the reference rate used in most interest rate swaps and futures contracts, in
most floating-rate mortgages, in many commercial loans, and in structured products such
as mortgage- and asset-backed securities. The list could go on and on, but the key point
is that LIBOR touches a large number of U.S. households and businesses.
Although LIBOR is currently used for all of these purposes, it is actually not
ideally suited for some of them. LIBOR is designed to measure the costs of bank
borrowing for a panel of large banks. The rate can be decomposed into a component that
reflects the general level of risk-free rates and a component that reflects a risk premium
related to the credit risk of the borrowing bank. During the global financial crisis, the
credit risk component of LIBOR fluctuated dramatically, which meant that LIBOR
behaved quite differently from rates with no credit risk embedded in them, such as riskfree rates.
LIBOR is a less-than-ideal rate for most derivatives contracts and secured
borrowing because movements in the credit risk component do not reflect well the
underlying risks of those contracts. However, LIBOR’s pervasiveness has become selfreinforcing. Firms use LIBOR in contracts, even when it is less than ideal, because they
know they can hedge the resulting risk using highly liquid, LIBOR-based interest rate
swaps or other derivatives contracts. And those derivatives markets are so liquid because

-5most market participants use LIBOR as the reference rate in their financial contracts.
Because of the progression of this dynamic over time, and not because of some careful
design, LIBOR has spread well beyond its intended uses and become an important pillar
of the global financial system--perhaps too important.
In recent years, two separate developments have called into question the wisdom
of that arrangement. I have already mentioned the first one--the emergence of a
pervasive pattern of attempted manipulation of LIBOR dating back many years. This
misconduct was designed either to increase the potential profit of the submitting firms or
to convey a misleading picture of the relative health of such firms. Since 2012, seven
financial institutions have settled related charges with the U.S. Commodity Futures
Trading Commission and the U.S. Department of Justice, and the cumulative penalties
and fines paid in the United States now stand at more than $3 billion.8 Global penalties
paid related to benchmark misconduct exceed $6 billion as investigations into reference
rate manipulation continue. Although these penalties and fines are themselves
substantial, to my mind the longer-term damage to the public’s trust represents the greater
cost of this misconduct.
A second problem is that unsecured interbank borrowing has been in a secular
decline that predates the global financial crisis. Changes in bank behavior following the
crisis exacerbated the decline and further weakened the foundation of LIBOR. The result
is a scarcity, or outright absence in longer tenors, of actual transactions that banks can use
to estimate their daily submission to LIBOR. Ongoing regulatory reforms and the shift
away from unsecured funding raise the possibility that unsecured interbank borrowing

-6transactions may become even more infrequent in the future. While it is also possible
that activity in these markets could rebound, the threat that this form of borrowing may
decline further, particularly in periods of stress, seems likely to remain.
So let me pose a question: Is it wise to rely on a critical benchmark that is built
on a market in decline? Clearly not. The risks to market functioning are simply too
great. For example, market activity could decline to the point where publication of a rate
becomes untenable. And many of the panel banks have expressed concerns about the
ongoing legal risks of remaining on the panel. If the publication of LIBOR were to
become untenable or if we were to simply “end LIBOR,” as some have urged, untangling
the $150 trillion in outstanding U.S. dollar LIBOR contracts would entail a protracted,
expensive, and uncertain process of negotiating amendments to an enormous number of
complex documents--a horrible mess and a feast for the legal profession, to be sure. It
does not help matters that the hundreds of trillions of dollars’ worth of derivatives
contracts referencing LIBOR do not, in general, have robust backups in the event that
publication of a rate ceases.
The FSB report identifies ways to improve U.S. dollar LIBOR, and to create
alternatives to it, while minimizing transition costs, particularly for end users who bear
no blame for the misconduct. The proposed reforms come down to two simple ideas.
First, U.S. dollar LIBOR needs to be redefined to include a broader range of transaction
types. Doing so will make it more robust and will allow it to reflect actual bank funding
costs, which is what the rate was intended to do in the first place. Second, we need to
promote robust alternatives to U.S. dollar LIBOR that better reflect the secured nature of
many of today’s financial market transactions.

-7Updating U.S. Dollar LIBOR
Let me first address the efforts the Federal Reserve is considering, in cooperation
with the LIBOR administrator and U.K. authorities, to update the mechanics of U.S.
dollar LIBOR. Our aim is to make LIBOR more robust and more representative of
current bank funding costs. In this regard, we have considered two important attributes
of LIBOR--its definition and the data used to produce it.
While the current definition of LIBOR is limited to unsecured borrowing between
banks, LIBOR is actually intended to represent the overall cost of banks’ unsecured
borrowing. At the time LIBOR was created, a substantial amount of that unsecured
borrowing was in the interbank market, but that is no longer the case. Broadening the
definition to include the unsecured borrowing from nonbanks would make the rate more
representative of current funding practices. Changing the definition of LIBOR, as has
been done in the past, would acknowledge the fact that a reference rate must adapt to
continue to represent what it is meant to measure.9
Updating the definition of U.S. dollar LIBOR could also allow other sources of
transactions data to be incorporated into it. Potentially, we could even move away from
the current panel-based method of calculating U.S. dollar LIBOR to a rate that is fully
transactions based. In April, the Federal Reserve began collecting data from banks on a

For a reference to a past change in LIBOR, see the British Bankers’ Association’s website “BBA LIBOR”
at www.bbalibor.com/disclaimer/explained/historical-perspective. The design of BBA LIBOR has seen
one significant change since its inception. Up until 1998, banks submitted quotes to the BBA LIBOR
process in line with the question “At what rate do you think interbank term deposits will be offered by one
prime bank to another prime bank for a reasonable market size today at 11 am?” During 1998, this
question changed and has, up until today, been as follows: “At what rate could you borrow funds, were
you to do so by asking for and then accepting inter-bank offers in a reasonable market size just prior to
11 am?” This decision was made after consultation with the markets and was implemented due to a view
that a universal definition of a prime bank could no longer be given. It also links the figures submitted by
banks to their own market activity rather than a hypothetical entity. For a reference to the usefulness of the
adaptability of reference rates, see Board of IOSCO, Principles for Financial Benchmarks, p. 12, in note 2.

-8variety of unsecured transactions. These data, along with other available data, will help
us understand whether there is enough borrowing activity to support a fully transactionsbased rate.10 It will take some time to assess these data and, in particular, to analyze the
depth of the markets under different conditions and during different times of the year.
But preliminary analysis, which is reinforced by research done by the Market Participants
Group (MPG) that was assembled by the FSB, suggests that there may be enough
borrowing activity to create a transactions-based U.S. dollar LIBOR rate.
Basing U.S. dollar LIBOR more on transactions could modestly increase the
volatility of the rate. However, I see nothing wrong with a reference rate that more
accurately reflects the volatility of the market it represents. We are working closely with
the LIBOR administrator, IBA, and with its regulator, FCA, to explore these issues. In
this regard, cooperation with IBA is crucial if LIBOR is to be strengthened--U.S. dollar
LIBOR is produced in the United Kingdom and is not regulated here in the United States.
The IOSCO review found that IBA has made progress in implementing most of the
19 IOSCO principles; the changes I have discussed are designed to continue this
progress, and I believe that IBA is well motivated to continue its efforts.11
Alternatives Needed
Improving U.S. dollar LIBOR alone cannot eliminate all of the weaknesses in the
current system. In the FSB’s opinion and that of the MPG, a large portion of the
derivatives that currently reference U.S. dollar LIBOR would be better served by

-9referencing a risk-free (or nearly risk-free) rate based on a robust and liquid underlying
market. These transactions are more appropriately linked to a narrower measure of
interest rates that does not include a bank credit risk component. Encouraging
alternatives that better reflect today’s funding markets would also allow for greater
choice, increase the resilience of the system, and would potentially make hedging of
some risks less costly. In addition, the incentive to manipulate LIBOR would be
substantially reduced if a smaller share of the multi-hundred-trillion-dollar derivatives
market was referencing it.
Some possible alternatives include rates based on the U.S. Treasury market or
rates based on the secured funding markets that have replaced much of the borrowing
banks used to do in the unsecured interbank market. The Federal Reserve is not seeking
to dictate the particular rate that financial markets adopt. Instead, we will encourage key
market participants to further the work done by the FSB’s MPG by narrowing down the
list of alternatives and developing them into robust reference rates that meet agreed-upon
international standards and best practices.12 There are enough suggestions on the MPG’s
list to inspire confidence that we should be able to find common ground. Any alternative
would, of course, need to be in accord with the IOSCO principles mentioned earlier, and
some potential alternatives would take time to fully develop. But the establishment of
alternative reference rates for certain products is in our shared interests and would
substantially strengthen the financial system.

- 10 We are strongly committed that at least one such rate be developed and actively
used as soon as practicable. And we look forward to working with financial institutions
and other market participants to achieve this end.
In the near term, the Federal Reserve, along with other government agencies,
intends to meet with a wide range of market participants, including end users, to hear
their views as to how change can be effected and to begin the work of developing
alternatives to LIBOR. Later this year, we will convene a group of the largest global
dealers to discuss these issues, following a model that was successfully used to promote
derivatives reform. Searching for potential alternative rates and encouraging their use
will be a key point of that discussion. Of course, end users will be affected by these
changes as well, and we will also consult closely with key participants outside of the
dealer community to make sure that reform meets their needs and is not disruptive to
them. In particular, end users who want to continue to use LIBOR will certainly be able
to do so, and we will work toward the goal of ensuring that any changes to LIBOR will
not require borrowers or lenders to amend their existing contracts. And the markets that
reference dollar LIBOR are so enormous that there will surely be more than enough
liquidity to support both a new risk free rate as well as LIBOR itself.
One of the lessons that I take from our study of LIBOR is that these existing
legacy contracts are quite important. As I mentioned earlier, many financial contracts,
including derivatives contracts, do not have robust backups in the event that the reference
rates they use cease to exist. Some derivatives, such as interest rate swaps, can be quite
long lasting, and, over a long enough period of time, there is always a risk that any given
reference rate will cease being published. It is important that financial contracts address

- 11 the need for a backup plan if a reference rate does cease to function. This issue is
something that we intend to bring up with market participants and end users as we meet
with them.
Conclusion
My hope is that governments, market participants, and end users can work
together to build a stronger foundation for the reference interest rates that are so critical
to our financial system. Implementation of these measures is clearly in the interest of
U.S. financial stability. I also hope and expect that individual financial institutions will
understand that it is also in their private interests. Reference rates are one of the
foundations of the financial system, and it is in the interest of everyone, from the
residential mortgage holder to the financial institutions that heavily use these rates, that
those foundations have integrity and be well constructed and resistant to manipulation.
As I said at the beginning, the problems with LIBOR have undermined the public’s trust
in the financial system. In light of the need to regain that trust, I am certain that our
reform efforts will meet with the active cooperation of financial institutions in carrying
forward these reforms.
