Remarks by Chairman Alan Greenspan
At the 2003 Conference on Bank Structure and Competition,

Corporate
governance
Corporate governance, the subject of our
conference, has evolved over the past century to more
effectively promote the allocation of the nation’s savings
to its most productive uses. And, generally speaking, the
resulting structure of business incentives, reporting, and
accountability has served us well. We could not have achieved
our current level of national productivity if corporate
governance had been deeply flawed.
Yet, our most recent experiences with
corporate malfeasance suggest that governance has strayed from
the way we think it is supposed to work. By law, shareholders
own our corporations, and corporate managers ideally should be
working on behalf of shareholders to allocate business
resources to their optimum use.
But as our economy has grown and our
business units have become ever larger, de facto shareholder
control has diminished: Ownership has become more dispersed,
and few shareholders have sufficient stakes to individually
influence the choice of boards of directors or chief executive
officers. The vast majority of corporate share ownership is
for investment, not for operating control of a company.
Thus, corporate officers, especially chief
executive officers, have increasingly shouldered the
responsibility for guiding businesses in what one hopes they
perceive to be the best interests of shareholders. Not all
CEOs have appropriately discharged their responsibilities and
lived up to the trust placed in them, as the events that led
to the passage of the Sarbanes-Oxley Act demonstrated. In too
many instances, some CEOs, under pressure to meet elevated
short-term expectations for earnings, employed accounting
devices for the sole purpose of obscuring adverse results.
A change in behavior, however, may already
be in train. The sharp decline in stock and bond prices after
the collapse of Enron and WorldCom has chastened many of those
responsible for questionable business practices. Corporate
reputation is emerging out of the ashes of the debacle as a
significant economic value. I hope that we will return to the
earlier practices of firms competing for the reputation of
having the most conservative and transparent set of books.
* * *
It is hard to overstate the importance of
reputation in a market economy. To be sure, a market economy
requires a structure of formal rules--a law of contracts,
bankruptcy statutes, a code of shareholder rights--to name but
a few. But rules cannot substitute for character. In virtually
all transactions, whether with customers or with colleagues,
we rely on the word of those with whom we do business. If we
could not do so, goods and services could not be exchanged
efficiently. Even when followed to the letter, rules guide
only a small number of the day-to-day decisions required of
corporate management. The rest are governed by whatever
personal code of values corporate managers bring to the table.
Market transactions are inhibited if
counterparties cannot rely on the accuracy of information. The
ability to trust the word of a stranger still is an integral
part of any sophisticated economy. A reputation for honest
dealings within a corporation is critical for effective
corporate governance. Even more important is the reputation of
the corporation itself as seen through the eyes of outsiders.
It is an exceptionally important market value that in
principle is capitalized on a balance sheet as goodwill.
Reputation and trust were particularly
valued assets in freewheeling nineteenth-century America.
Throughout much of that century, laissez-faire reigned and
caveat emptor was the prevailing prescription for guarding
against the wide-open trading practices of those years. A
reputation for honest dealings was thus a particularly valued
asset. Even those inclined to be less than scrupulous in their
private dealings were forced to adhere to a more ethical
standard in their market transactions, or they risked being
driven out of business.
To be sure, the history of business is
strewn with Fisks, Goulds, and numerous others treading on, or
over, the edge of legality. But they were a distinct minority.
If the situation had been otherwise, the United States at the
end of the nineteenth century would never have been poised to
displace Great Britain as the world’s leading economy.
Reputation was especially important to early
U.S. bankers. It is not by chance that in the nineteenth
century many bankers could effectively issue uncollateralized
currency. They worked hard to develop and maintain a
reputation that their word was their bond. For these
institutions to succeed and prosper, people had to trust their
promise of redemption in specie. The notion that “wildcat
banking” was rampant before the Civil War is an
exaggeration. Certainly, crooks existed in banking as in every
business. Some banks that issued currency made redemption
inconvenient, if not impossible. But they were fly-by-night
operators and rarely endured beyond the first swindle.
In fact, most bankers competed vigorously
for reputation. Those who had a history of redeeming their
bank notes in specie, at par, were able to issue substantial
quantities, effectively financing their balance sheets with
zero-interest debt. J.P. Morgan marshaled immense power on
Wall Street in large part because his reputation for
fulfilling his promises was legendary.
Today, most banks rely partly on deposit
insurance in lieu of reputation to hold below-market-rate
deposits. And a broad range of protections provided by the
Securities and Exchange Commission, the Commodity Futures
Trading Commission, and myriad other federal and state
agencies has similarly partially crowded out the value of
trust as a competitive asset.
* * *
Trust still plays a crucial role in one of the
most rapidly growing segments of our financial system--the
over-the-counter (OTC) derivatives market. This market has
played an important and successful role in the management of
risk at financial institutions, a major element of their
corporate governance. I do not say that the success of the OTC
derivatives market in creating greater financial flexibility
is due solely to the prevalence of private reputation rather
than public regulation. Still, the success to date clearly
could not have been achieved were it not for counterparties’
substantial freedom from regulatory constraints on the terms
of OTC contracts. This freedom allows derivatives
counterparties to craft contracts that transfer risks in the
most effective way to those most willing and financially
capable of absorbing them.
Benefits of Derivatives
Although the benefits and costs of derivatives remain the
subject of spirited debate, the performance of the economy and
the financial system in recent years suggests that those
benefits have materially exceeded the costs. Over the past
several years, the U.S. economy has proven remarkably
resilient in the face of a series of severe shocks--the
collapse of equity values, terrorist attacks, and geopolitical
turmoil. To be sure, economic growth has been subpar for some
time, but we seem to have experienced a significantly milder
downturn than the long history of business cycles and the
severity of the shocks to the economy would have led us to
expect.
Although no single factor can account for
this resilience, one striking feature that differentiates this
cycle from earlier ones is the continued vitality of most U.S.
banks and nonbank financial institutions. In past cycles,
economic downturns often produced credit losses that were so
severe that the capacity of those institutions to intermediate
financial flows was impaired. As a consequence, recessions
were prolonged and deepened. This time, the economic downturn
has not significantly eroded the capital of most financial
intermediaries, and the terms and availability of credit have
not tightened to such an extent as to be significant factors
in deepening the contraction or impeding the recovery.
The use of a growing array of derivatives
and the related application of more-sophisticated methods for
measuring and managing risk are key factors underpinning the
enhanced resilience of our largest financial intermediaries.
Derivatives have permitted financial risks to be unbundled in
ways that have facilitated both their measurement and their
management. Because risks can be unbundled, individual
financial instruments now can be analyzed in terms of their
common underlying risk factors, and risks can be managed on a
portfolio basis. Concentrations of risk are more readily
identified, and when such concentrations exceed the risk
appetites of intermediaries, derivatives can be employed to
transfer the underlying risks to other entities.
As a result, not only have individual
financial institutions become less vulnerable to shocks from
underlying risk factors, but also the financial system as a
whole has become more resilient. Individual institutions’
portfolios have become better diversified. Furthermore, risk
is more widely dispersed, both within the banking system and
among other types of intermediaries and institutional
investors. Even the largest corporate defaults in history
(WorldCom and Enron) and the largest sovereign default in
history (Argentina) have not significantly impaired the
capital of any major financial intermediary.
Likewise, record amounts of home mortgage
refinancing and accompanying declines in mortgage asset
durations have not imperiled the principal intermediaries in
the mortgage markets, in substantial part because these
institutions were able to use derivatives to transfer a
significant portion of the convexity risk associated with
prepayments of fixed-rate mortgages to investors in callable
debt and issuers of putable debt.
Risks Associated with the Use of
Derivatives
If derivatives and the techniques for risk measurement and
management that they have facilitated have produced all these
benefits, why do they remain so controversial? The answer is
that the use of these instruments and the associated
techniques pose a variety of challenges to risk managers.
Inevitably, risk-management failures occur, and in two
instances--the highly publicized cases of Barings and Long
Term Capital Management--they proved destabilizing. Those that
question the net benefits of derivatives see daunting
risk-management problems and thus foresee catastrophic
outcomes. In particular, they fear that common deficiencies in
risk management will result in widespread failures or that the
failure of a very large derivatives participant will impose
heavy credit losses on its counterparties and yield a chain of
failures.
Others, like myself, who see the benefits of
derivatives exceeding the costs, do not deny that their use
poses significant risk-management challenges. But we see ample
evidence that the risks are manageable in principle and
generally have been managed quite effectively in practice, at
least to date. Indeed, credit losses on derivatives have
occurred at a rate that is a small fraction, for example, of
the loss rate on commercial and industrial loans. Market
discipline in the largely unregulated derivatives markets has
provided strong incentives for effective risk management and
has the potential to be even more effective in the future.
To be sure, there undoubtedly will be
further risk-management failures. But the largest market
participants have such diversified businesses that a
risk-management failure involving a single product line is
unlikely to be a threat to solvency. Furthermore,
risk-management failures are more likely to be idiosyncratic
than to reflect common deficiencies in procedure or technique
among market participants. In the case of the management of
market risk, our bank examiners observe significant
differences in approach across the largest U.S. banks, even in
the measurement of such a basic concept as value-at-risk.
I do not wish to suggest, however, that I am
entirely sanguine with respect to the risks associated with
derivatives. One development that gives me and others some
pause is the decline in the number of major derivatives
dealers and its potential implications for market liquidity
and for concentration of counterparty credit risks. I also
fear that the potential contribution of market discipline to
stability in the derivatives markets is not being fully
realized because, in our laudable efforts to improve public
disclosure, we too often appear to be mistaking more extensive
disclosure for greater transparency. This is an issue to which
I shall shortly return.
Concentration and Market Liquidity
In recent years, consolidation has reduced the number of firms
that provide liquidity to the OTC derivatives markets by
acting as dealers in the more standardized or “plain
vanilla” contracts. To be sure, the resulting concentration
sometimes is overstated because of the failure to recognize
that the OTC derivatives markets are global markets in which
major banks and securities firms from more than half a dozen
countries compete. For example, measures of concentration
based on data reported by U.S. banks overstate concentration
significantly because they ignore the competitive activities
of U.S. securities firms and foreign banks.
Nonetheless, not all major dealers make
markets in all products, and concentration is substantial for
certain important types of OTC contracts. Examples include
U.S. dollar interest rate options and credit default swaps. In
each case, a single dealer seems to account for about
one-third of the global market, and a handful of dealers
together seem to account for more than two-thirds.
When concentration reaches these kinds of
levels, market participants need to consider the implications
of exit by one or more leading dealers. Such an event could
adversely affect the liquidity of types of derivatives that
market participants rely upon for managing the risks of their
core business functions.
Exit could be voluntary. In particular,
losses incurred in making markets could lead a dealer to
conclude that the returns from market-making are not
commensurate with the risks. Alternatively, downgrades of a
dealer’s credit rating could force the dealer to exit.
Counterparties in the OTC derivatives market are quite
concerned about the potential credit risks inherent in such
contracts and generally are unwilling to transact with dealers
unless their credit rating is A or higher.
If a major dealer exited and other dealers
were unwilling to fill the void, the liquidity of the market
likely would be impaired. Market participants need to consider
what their alternatives would be in such circumstances. Are
there other liquid markets in which they could manage their
risks? In some cases market participants may be able to manage
risks reasonably effectively in cash markets or
exchange-traded derivatives markets. But in other cases
managing risks may become more difficult with the exit of some
dealers. If market participants perceive that they are
vulnerable to such exit by a liquidity provider, they will
tend to redirect some of their risk-management activity to
other, more liquid markets or seek out new dealers in the
market in which exit is a concern. If enough participants
perceive the concentration of dealers as entailing
market-liquidity risk, their actions to mitigate the risk
should over time reduce that degree of concentration.
Concentration and Counterparty Risk
Perhaps the more obvious way in which concentration in OTC
derivatives markets creates risks for market participants is
through its implications for counterparty credit risks.
Concentration of market-making has the potential to create
concentrations of credit risks between the dealers and the
end-users of derivatives as well as between the dealers
themselves. This latter concentration of risk results from
dealers frequently managing their market risks through
derivatives transactions with a limited number of other
dealers. As mentioned earlier, critics of derivatives often
raise the specter of the failure of one dealer imposing
debilitating losses on its counterparties, including other
dealers, yielding a chain of defaults.
However, derivatives market participants
seem keenly aware of the counterparty credit risks associated
with derivatives and take various measures to mitigate those
risks. The vast majority carefully evaluate the
creditworthiness of counterparties before entering into
transactions and monitor their credit quality over the life of
the transactions. As I indicated earlier, users of derivatives
have been reluctant to transact with dealers that are not
perceived as solid investment-grade credits. Market
participants also establish credit limits for their
counterparties and actively monitor their exposures to ensure
that they remain within the limits established. Such
monitoring, parenthetically, relies heavily on trust in the
accuracy of the information forthcoming from the
counterparties.
Counterparty risk management has been
materially assisted by the widespread use of master agreements
for derivatives transactions. In the event of a
counterparty’s default, such agreements permit the
termination of all transactions with the counterparty and the
netting of the resulting gains and losses. For many years,
market participants have been putting such master agreements
in place and working with legislatures to ensure that national
laws support the enforceability of netting. Data reported by
U.S. banks indicate that, on average, netting now reduces
counterparty exposures by almost three-fourths.
Even with wider use of netting, however, the
outsized growth of derivatives markets has resulted in
ever-larger counterparty exposures. Market participants have
increasingly responded by entering into collateral agreements
to further mitigate counterparty credit risks. Such agreements
typically permit counterparties to derivatives transactions to
demand collateral if their net credit exposure exceeds a
negotiated threshold amount. The threshold often varies with
the credit rating of the counterparty: The lower a
counterparty’s credit rating, the smaller the threshold. If
its credit rating falls below investment grade, a counterparty
is often required to overcollateralize its counterparties’
exposures. In effect, it becomes obligated to meet a margin
requirement.
Collateral agreements are a very effective
means of limiting counterparty credit risks. At the same time,
they increase market participants’ exposures to other types
of risk, especially funding-liquidity risks. Once a
counterparty has agreed to collateralize its derivatives
contracts, day-to-day declines in the value of those contracts
expose it to immediate demands for more collateral.
Furthermore, the practice of tying the size of thresholds and
margin requirements to credit ratings exposes a counterparty
to extraordinary demands for collateral if its rating is
downgraded. Collateral demands arising from rating downgrades
may be especially costly to meet because a downgrade would
reduce the availability of funding and increase its costs at
the same time.
Incentives for Effective Risk Management
As this discussion of the risks associated with derivatives
makes clear, effective risk management by market participants
is the key to ensuring that the benefits of derivatives
continue to exceed their costs.
Some may see government regulation of OTC
derivatives dealers as essential to ensuring efficacious risk
management. This view presumes that government regulation can
address the challenges these types of markets engender and
that it can do so without lessening the effectiveness of
market discipline supplied by counterparties. Market
participants usually have strong incentives to monitor and
control the risks they assume in choosing to deal with
particular counterparties. In essence, prudential regulation
is supplied by the market through counterparty evaluation and
monitoring rather than by authorities. Such private prudential
regulation can be impaired--indeed, even displaced--if some
counterparties assume that government regulations obviate
private prudence.
We regulators are often perceived as
constraining excessive risk-taking more effectively than is
demonstrably possible in practice. Except where market
discipline is undermined by moral hazard, owing, for example,
to federal guarantees of private debt, private regulation
generally is far better at constraining excessive risk-taking
than is government regulation.
The very modest credit losses that have
appeared in derivatives portfolios at U.S. banks are a
testament to the effectiveness of market discipline in this
area. Indeed, credit losses on OTC derivatives also have been
quite modest at derivatives affiliates of U.S. broker-dealers,
which are subject to very limited government regulation. This
is further evidence of the powerful effects on behavior that
result when market participants recognize that they bear the
bottom-line consequences of their risk-taking decisions.
A key support for market discipline is the
information that market participants have for evaluating the
creditworthiness of counterparties. Over the past decade,
enormous attention has been given to disclosures market
participants make with regard to their risk exposures,
particularly those associated with derivatives activities.
Both public authorities and private-sector working groups have
recommended ways to enhance market discipline through improved
public disclosures. The result of these efforts, however, has
been mixed.
Clearly, we have made great strides in
expanding the volume of publicly disclosed information related
to risk exposures and derivatives. A more complex question is
whether this greater volume of information has led to
comparable improvements in the transparency of firms.
In the minds of some, public disclosure and
transparency are interchangeable. But they are not.
Transparency implies that information allows an understanding
of a firm's exposures and risks without distortion. The goal
of improved transparency thus represents a higher bar than the
goal of improved disclosures. Transparency challenges market
participants not only to provide information but also to place
that information in a context that makes it meaningful.
Transparency challenges market participants to present
information in ways that accurately reflect risks. Much
disclosure currently falls short of these more demanding
goals.
Despite the substantial room for progress
with regard to transparency, we should not underestimate the
barriers to achieving it. Managers no doubt have to struggle
with selecting and organizing data in a meaningful way. The
difficulties are well illustrated by the annual reports of
large institutions that routinely exceed one hundred pages;
pressures are enormous to update existing tables and charts as
well as to provide even more. In addressing this challenge,
however, both managers of firms and makers of public policy
would do well to be mindful of the ultimate goal--a clear
understanding of a firm's activities that fosters market
discipline.
Conclusion
In conclusion, the benefits of derivatives, in my judgment,
have far exceeded their costs. Derivatives unquestionably do
pose risk-management challenges to market participants. But
those challenges are manageable and thus far have generally
been managed quite well. The best way to ensure that those
challenges continue to be met is to preserve and strengthen
the effectiveness of market discipline. Market incentives, in
particular, reinforce the importance of reputation and trust
as sources of market value.
Just as market discipline has fostered
effective risk management in the derivatives markets, so too
it is now being brought to bear on corporate governance
generally. Once market discipline firmly reestablishes
reputation and trust as corporate values, the incidence of
corporate malfeasance should be greatly reduced.
