Here’s what the experts are saying about
Safeguarding Financial Stability
Theory and Practice
By Garry J. Schinasi
Safeguarding Financial Stability explicates why financial stability matters,
what it means, and the challenges in securing it....[It is] a thoughtful
and thought-provoking volume that is a must read not just for central
bankers but for all concerned with financial stability—and if you are not
concerned about the latter, you soon will be!”
—Gerard Caprio, Jr., World Bank
Garry Schinasi provides a unique and comprehensive framework for
understanding financial stability and for assessing the risks posed by new
financial instruments in increasingly unregulated markets in an increas-
ingly globalized world. The channels of monetary policy management
have changed tremendously, as anyone who follows the striking stability of
long-term bond yields in the face of rising short-term interest rates will
attest. The global business cycle is maturing, entering into a period of high
financial risk, as discussed by Dr. Schinasi. Anyone who does not read this
book today will regret not doing so, as the next financial shock and test of
the stability of the global financial system is not long in coming.

...this is a great book. It synthesizes a large literature on financial stabil-
ity,...and it fills in a number of crucial holes....I think it will be
remembered as the first concrete attempt to analyze, define, and move
toward operationalizing assessment of financial stability.

Preface
T
his book was written because I could not find one like it in bookstores
or in central bank libraries. In effect, it fills a gap—albeit imperfectly—
in the existing policy, academic, and commercial literatures on financial
stability issues.
The motivation for undertaking this project came to me in early 2003,
after having spent nearly 10 years engaging in international capital market
surveillance—first in the IMF’s Research Department (both as Deputy
Chief and Chief of the Capital Market and Financial Studies Division) and
then in the newly created International Capital Markets Department (as
Chief of the Financial Markets Stability Division). Part of the challenge of
the job was to understand the implications of structural changes in
finance (including financial institutions, markets, and infrastructures),
which required talking to market participants and the relevant authori-
ties (including central banks and supervisory authorities). The job always
entailed keeping management and colleagues well informed about capi-
tal market developments, prospects, issues, and most important, sources
of risks and vulnerabilities.
The time spent searching for potential risks and vulnerabilities (or pot-
holes” as we called them) in the international monetary and financial sys-
tem, especially in the more mature markets, challenged my colleagues and
me to search continuously for new ways of understanding how calm mar-
ket conditions can lead to turbulence, why changes in market sentiment
often occur without much warning, and how the private and official sec-
tors can adapt and learn to prevent and better cope with financial difficul-
ties and crises. By mid-2003 I felt it was time to step back from the events
as they were occurring and to reflect more systematically—and with less
pressure—on what kind of framework would advance the understanding
of financial stability issues, how to communicate the importance of these
issues, and how to encourage and energize a greater focus on optimizing
the benefits of finance for societies at large.
Before actually reaching the decision to take a one year sabbatical from
the IMF, I challenged myself to produce an outline of a study on financial
stability issues that I was fairly certain I could write, if given sufficient free
xi
time. Instead, I produced an outline of a book that I wanted to read, but
which I was uncertain I was capable of writing. I will leave it to the reader
to decide whether the outcome was worth the effort. My only hope in pub-
lishing this study is that practitioners—that is, those who safeguard finan-
cial stability—will be motivated to think about these issues in a new and
more productive way and that the relevant professions will be encouraged
to develop useful, policy-oriented frameworks for achieving and maintain-
ing national and international financial stability.

his study was researched and partly written during a one-year sabbati-
cal from the International Monetary Fund (IMF). I gratefully acknowl-
edge the IMF’s generous financial support under its Independent Study
Leave Program.
I also gratefully acknowledge the support and encouragement of the
European Central Bank (ECB) and De Nederlandsche Bank (DNB) while
visiting them in 2003 and 2004, and would like to thank especially Tom-
maso Padoa-Schioppa, Mauro Grande, and John Fell at ECB and Henk
Brouwer, Jan Brockmeijer, Aerdt Houben, and Jan Kakes at DNB.
Chapters 2, 3, 5, and 6 are based, in part, on material researched and pre-
sented in various drafts of several papers (which were later revised and
repackaged and issued as IMF Working Papers WP/04/101, WP/04/120,
and WP/04/187). These and other related papers benefited from discus-
sions with, and comments from, many colleagues both within and outside
the IMF. These include Bill Alexander, Ivan Alves, Michael Bordo, Burkhard
Drees, Christine Cumming, Udaibir Das, Phil Davis, Charlie Kramer,
Myron Kwast, John Fell, Bob Flood, Andy Haldane, Aerdt Houben, Jan
Kakes, Russell Kincaid, Donald Mathieson, Leena Mörttinen, Tommaso

received useful comments during seminars at ECB, DNB, the European
Investment Bank, the University of Hong Kong, and from other IMF col-
leagues during the review process for IMF working papers.
The chapters presented in Part III of this study are based, at least in part,
on material that was originally cowritten with IMF colleagues and pub-
lished in various editions of the IMF’s International Capital Markets—
Develop

Financial Stability Report during 2002–2003. I would like to acknowledge the
following coauthors for their contributions to this earlier work and the more
recent manifestations of it presented in this study: Charlie Kramer (Chapters
9, 10, and 11); Burkhard Drees (Chapter 9); Todd Smith (Chapter 10); Peter
Breuer (Chapter 11); and Oksana Khadarina provided essential assistance
in preparing the quantitative part of Chapter 8. I am also grateful to my
coauthors Aerdt Houben and Jan Kakes (of DNB) for allowing me to use
material from our joint IMF Working Paper WP04/101 and DNB Occasional
Paper, “Toward a Framework for Safeguarding Financial Stability, which we
jointly researched, brainstormed, and drafted during a four-month period
ending in mid-February 2004, and which makes up part of Chapter 6. I am
grateful to my coauthor John Fell for allowing me to use material from our
joint paper, Assessing Financial Stability: Exploring the Boundaries of
Analysis, published in a special financial-stability edition of National Insti-
tute Economic Review (April 2005). I am especially grateful to John Fell for
providing a fertile environment at ECB for the early stages of my work and
for his persistent encouragement to complete this project. In all other
instances in which I use material drawn from the work of colleagues both
within and outside the IMF it is acknowledged in footnotes. I am grateful to
Oksana Khadarina for untiring efforts in producing and updating the tables
and charts and also to Yoon Kim for assisting in a part of this effort. Special
thanks to Margo and Tom Vuicich for providing a sunny environment for
thinking and writing part of this study.
Thanks are due also to Jeanette Morrison, Anne Logue, and Sherrie
Brown for their editorial and publishing expertise. I am particularly grate-
ful to Sean M. Culhane for providing expert professional advice and
encouragement during each phase of the editorial and production process.
I owe thanks to Michael Mussa (IMF Economic Counsellor and Director
of Research, 1993–2001) and David Folkerts-Landau (Assistant Director of
Research until 1998) for providing me with the opportunity to be a part of
the IMF’s international capital markets surveillance team in 1994–95.
Finally, I thank Katherine, Jack, and Sarah for their loving support
throughout these and many other efforts.

Introduction and Summary
T
he objective of this book is to develop and present a framework for safe-
guarding financial stability. Part I reviews important logical founda-
tions that show how the process of finance is related to real economic
processes and why finance can and should be viewed as providing public
goods and requiring forms of private-collective and public policy action. Part
II proposes and develops a comprehensive and practical framework for safe-
guarding financial stability encompassing both the prevention and the reso-
lution of financial imbalances, problems, and crises. Part III examines
ongoing real world challenges to financial stability posed by recent structural
financial changes such as the globalization of finance, the growing reliance
on over-the-counter derivative instruments and markets, the growth of credit
derivatives markets, and the capital market activities of insurance and rein-
surance companies.
This Book and the Financial Stability Questions
Does financial stability require the soundness of institutions, the stability
of markets, the absence of turbulence, and low volatility—or something
even more fundamental? Can stability be achieved and maintained through
individual private actions and unfettered market forces alone? If not, what is
the role of the public sector, as opposed to private-collective action, in fos-
tering financial stability? Should the public sector just make way for the pri-
vate sector to achieve an optimum on its own, or is a more proactive role
necessary for achieving the full private and social benefits of finance? Is there
aconsensus on how to achieve and maintain financial stability?
The role of the public sector is not likely to be clear and appropriately
focused without an understanding of the requirements for financial stabil-
ity in the first place. Likewise, the requirements for financial stability are not
1
likely to be well understood without an analytical framework that can rig-
orously consider the questions above, individually and collectively. Unfor-
tunately, there is no single, widely accepted framework for monitoring,
assessing, and safeguarding financial stability; in fact, there is not even a
widely accepted definition of financial stability. Perhaps this is the root of
the problem, because without a good working definition of financial stabil-
ity, the quickly growing financial-stability profession will continue to have
difficulties developing useful analytical frameworks for examining policy
issues, for monitoring and assessing the financial-stability performance of
financial systems, and for dealing with financial systemic problems should
they arise.
The core objective of this study is to develop a practical framework for
safeguarding financial stability. As anyone who has tried to engage in
financial-stability analysis knows, there are few if any widely accepted
models or analytical frameworks for monitoring and assessing financial-
system stability and for examining policy issues, as there are for economic
systems and in other disciplines. The practice of financial-stability analysis
is still in its infancy when compared with, for example, the analysis of mon-
etary stability or macroeconomic stability. In the rare cases in which finan-
cial systems are expressed rigorously, they constitute one or two equations
in much larger macroeconomic models possessing most of the usual macro-
equilibrium and macro-stability conditions. In addition, there are reasons
to doubt strongly that a single measurable target variable can be found for
defining and achieving financial stability, as there is believed to be for defin-
ing and achieving monetary stability (such as an inflation target), although
many doubt that a single target variable approach accurately represents
actual practice in monetary policymaking.
Lacking a framework for financial stability, a set of models for analyzing
and understanding it, or even a concept of financial-system equilibrium and
stability, it is difficult to envision a framework for safeguarding financial sta-
bility (including a practical definition) akin to what economists normally
demand and use. Nevertheless, it would be useful to have a framework that
not only encompasses, but also requires, the continuous development and
use of both analytical tools and policy analyses.
This study develops and proposes such a framework. The approach
developed here is not a final blueprint, however, and it should be seen as
one further step in the evolution of the practice of safeguarding financial
stability. In researching and writing about many of the issues the book
addresses, the choice often had to be made to be practical and policy rele-
vant rather than scientific and rigorous, in part because assessing financial
stability is still more of an art form than a rigorous discipline or science.

INTRODUCTION AND SUMMARY
Accordingly, there is great scope for more scientific and rigorous efforts, as
will be discussed later in the study.
The Increasing Importance of Financial Stability Issues
Since the early 1990s, safeguarding financial stability has become an
increasingly dominant objective in economic policymaking. This is illus-
trated by the periodic financial stability reports launched by more than a
dozen central banks and several international financial institutions
(including the IMF, the Bank for International Settlements [BIS], and the
World Bank), as well as by the more prominent place given to financial sta-
bility in the organizational structures and mandates of many of these insti-
tutions. The greater emphasis on financial stability is related to several major
trends in financial systems during the past few decades. These trends reflect
the expansion, liberalization, and subsequent globalization of financial sys-
tems—all of which have increased the possibility of larger adverse conse-
quences of financial instability on economic performance (see Chapter 8 of
this volume on the potential effects of globalization).
First, financial systems expanded at a significantly higher pace than the
real economy. In advanced economies, total financial assets now represent a
multiple of annual economic production. Table 1.1 illustrates this expansion
over the period 1970–2004 for a heterogeneous group of advanced economies
with relatively mature financial systems. For example, while currency
remained relatively steady as a percentage of GDP over the period, total assets
in financial institutions grew from 110 percent of GDP in 1980 to 377 per-
cent in 2000 in the United Kingdom, from 182 percent in 1980 to 353 percent
in 2000 in Germany, and from 111 percent in 1980 to 257 percent in 2000 in
the United States. The growth of assets in the equity and bond markets is
just as phenomenal. While differences between countries reflect their more
market- or bank-oriented financial systems, most aggregates have increased.
The broad measures of an economy’s total financial assets invariably involve
some double counting due to claims between financial institutions, but even
these mutual holdings are relevant for financial stability because they repre-
sent the links, interactions, and complexities in the financial system.
Second, this process of financial deepening has been accompanied by
changes in the composition of the financial system, with a declining share
of monetary assets (aggregates), an increasing share of nonmonetary assets,
and, by implication, greater leverage of the monetary base. The amount of
currency relative to GDP has been broadly stable or decreased in all coun-

increasing importance of narrow money in the 1990s may be attributable
to greater incentives to hold money due to the Japanese financial sector’s
fragile state and enduring deflationary pressures.
The simple average expansion of the financial systems shown in Table 1.1
is illustrated in Figure 1.1, in which total assets of financial institutions are
reflected by the triangles surface. Figure 1.1 shows rather dramatically that
between 1970 and 2000 the size of these assets almost tripled relative to
GDP. Note also how the average of the financial systems has become more
highly leveraged, in the sense that the broader monetary and financial assets
represent a much greater share of the triangle in 2000 than in 1970 relative
to central bank money (or currency).

Figure 1.2 shows the change in composition of the financial system over
the past decades by expressing key financial aggregates as a percentage of
their value in 1970 (all deflated by GDP). Clearly, the relative importance
of monetary aggregates has decreased, while nonmonetary components
have increased rapidly.
Third, as a result of increasing cross-industry and cross-border inte-
gration, financial systems are more integrated, both nationally and inter-
nationally. Financial institutions now encompass a broader range of
activities than that of a traditional bank, which takes deposits and extends
loans. This is reflected in the rise in financial conglomerates, which provide
avast array of banking, underwriting, brokering, asset-management, and
insurance products and services.

In the 1990s, the number of mergers and
acquisitions within the financial sector soared (Figure 1.3). Some of these
transactions involved different industries or countries, especially in Europe
where roughly half the deals in this period were either cross-border, cross-
industry, or both (Table 1.2). In addition, cooperation between financial
institutions intensified through joint ventures and strategic alliances. The
greater international orientation of financial systems is also reflected in the

increasing size of cross-border transactions in bonds and equity relative
to GDP (see Table 1.3). On this score, the amount of outstanding inter-
national debt securities surged over the past decades (Table 1.4).
Fourth, the financial system has become more complex in terms of the
intricacy of financial instruments, the diversity of activities, and the concomi-
tant mobility of risks. Deregulation and liberalization created scope for finan-
cial innovation and enhanced the mobility of risks. In general, this greater
complexity, especially the increase in risk transfers (see Chapter 10), has
made it more difficult for market participants, supervisors, and policymakers
alike to track the development of risks within the system and over time. To
illustrate the higher mobility of risks, Table 1.5 presents the worldwide devel-
opment of several types of derivatives since the mid-1980s. In nominal terms,
total notional amounts outstanding have increased more than 40 times, while
the number of derivative contracts has increased fivefold. (Chapter 9 pro-
vides a description of the potential risks to financial stability introduced by
the widespread and more active use of over-the-counter derivatives.)
These trends and developments reflect important advances in finance
that have contributed substantially to economic efficiency, both nationally
and internationally. They evidently also have had implications for the
nature of financial risks and vulnerabilities and the potential impact of risks
and vulnerabilities on real economies, as well as implications for the role of
policymakers in promoting financial stability. Consider financial system
and market developments in the 1990s and early 2000s—a period during
which global inflation pressures subsided and in many countries were elim-
inated. During this period, reflecting in part the above-mentioned trends,
national financial systems around the world either experienced, or were

exposed to, repeated episodes of unpleasant financial-market dynamics
including asset-price volatility and misalignments; volatile if not unsustain-
able financial and capital flows; extreme market turbulence, at times leading
to concerns about potential systemic consequences; and a succession of
costly country crises in 1994–95, 1997, 1998, 1999, and in the early 2000s
(Table 1.6). The experiences of, and fallout from, these financial stresses and
strains occurred within both advanced countries with highly sophisticated
financial markets and developing countries with financial systems of vary-
ing degrees of immaturity and dysfunction.
As these developments were occurring, economic and financial policy-
makers became increasingly concerned that global financial stability was
becoming more difficult to safeguard.
The Need for an Analytical Framework
While dealing with the urgencies of financial-market and country crises
in the 1990s, those situated at the front lines of financial-system policy-
making—including at the major central banks and supervisory authorities,
and at the IMF—searched widely and intensively for ways to advance their
understanding of the ongoing problems and to reform national and inter-
national financial architectures to prevent and better cope with the
potential for financial distress and crises. Some lessons were learned and
efforts made to reform the rules of the game of international finance, many
of which are documented in case studies and review articles.

over member countries’ macroeconomic policies, to assess national finan-
cial systems compliance with international financial standards and codes
(under the new and voluntary Financial Sector Assessment Program imple-
mented jointly with the World Bank), and to enhance its multilateral sur-
veillance of the global economy and financial system. Moreover, there is also
now a general sense that policy responses in the future are likely to require
coordination between a greater number of authorities from a greater num-
ber of countries.
As a result of these experiences and lessons, safeguarding financial stabil-
ity is widely recognized as important to maintaining macroeconomic and
monetary stability, and to achieving sustainable growth. Many advanced-
country central banks (including under the auspices of the Bank for Inter-
national Settlements), as well as the IMF, devote considerable resources to
monitoring and assessing financial stability and to publishing financial-
stability reports. A casual reading of these publications would suggest that
financial-stability practitioners share some common understandings:
Finance is fundamentally different from other economic functions such
as exchange, production, and resource allocation.
Finance contributes importantly to other economic functions and facil-
itates economic development, growth, efficiency, and ultimately
social
prosperity.
Financial stability is an important social objective—a public good—
even if it is not widely seen as being on par with monetary stability.
•Monetary and financial stability are closely related, if not inextricably
intertwined, even though there is no consensus on why this is so.

The academic literature also continues to grow, much of it covering spe-
cific financial-stability topics in considerable depth and some of it provid-
ing rigorous anchors for debating substantive and policy issues. For
example, the extensive literature on banking covers the special role and
fragility of banks in finance; the costs and benefits of deposit insurance;
and the causes, consequences, and remedies for bank failures. Moreover,
recent empirical studies have highlighted the rising incidence of banking
crises,
3
as well as their considerable costs.
4
At the same time, central bank
concerns with financial stability are as old as central banks themselves,
given their ultimate responsibility for confidence in the national currency.
5
For example, the principal reason for the founding of the U.S. Federal
Reserve System in 1913 was to assure stable and smoothly functioning
financial and payments systems.
6
The literature on market sources of
financial fragility and systemic risk more generally also continues to grow.

Despite this practical and intellectual progress in financial-stability
analysis in recent years, it is still in a formative stage when compared with
macroeconomic and monetary analysis. The various literatures taken
together do not yet provide cohesive and practical toolkits useful for think-
ing about and analyzing systemic financial-stability issues and controversies,
for monitoring and assessing financial stability in real time, for preventing
problems from becoming potentially systemic, for resolving them when
they do occur, and for designing policies more broadly to optimize the net
social benefits of finance. Even the now ubiquitous phrase “financial stabil-
ity” has no widely understood and accepted definition.
In short, the discipline lacks a generally accepted and useful “frame-
work.” To use a nautical metaphor—and to exaggerate somewhat—the
profession is sailing on the high and at times turbulent seas with neither a
well-conceived and time-tested map nor a reliable compass. The fact that
many advanced-country financial markets and the international financial
system remained resilient and that financial resilience (if not stability) has
been reasonably well maintained in the early 2000s—especially in the
mature markets—may have as much to do with good luck as with success-
ful preventive policy design and market surveillance.
8
That this is so is no fault of the relevant professions. It is an occupational
hazard that financial crises are difficult to foresee, even when they are closely
upon us. The financial world has changed rapidly, the problems requiring
solutions are complicated, and stresses and strains arise within a poorly
understood set of dynamic financial markets and institutions. In short, the
challenges have been and still are daunting, even with important progress
in understanding specific financial-stability issues.
Although the movement toward greater attention for financial-stability
issues is clear, the point of focus of this attention is not. Consensus has yet to
be reached on how to define the concept of financial stability, how to assess
developments under this objective, and what role public policy should play.
Nevertheless, the practice of assessing and safeguarding financial stabil-
ity is ongoing.
Specific Objectives of This Study
In this light, this study proposes a basic framework for financial-stability
analysis and policy. At its core, the study develops both a working defini-

tion of financial stability and a broad practical framework for monitoring,
assessing, and maintaining it. Although most financial systems are still ana-
lyzed at the national level, the scope of this framework can be easily
extended to international financial-stability issues.
One possible reason for the lack of a widely accepted definition of finan-
cial stability and a framework is that there is no widely accepted or articu-
lated logical foundation for why private finance should be the purview of
collective action, including public policy action and involvement. Modern
finance is often portrayed to nonspecialists as a purely private activity hav-
ing little to do with, or need for, private-collective or government involve-
ment. Likewise, the benefits of finance are seen primarily, if not exclusively,
as conveying to private counterparts engaged in specific financial activities
and markets.
While there is some truth in the characterization of finance as primarily
a private affair, it would be an illusion to evaluate the effectiveness of private
finance and its enormous real economic benefits either entirely as private or
exclusively as the result of individual private actions and unrestrained mar-
ket forces. Regardless of what is thought about the necessity and efficacy of
collective action and public policies, obtaining the full extent of the private
net benefits of modern finance requires, at a minimum, the existence and
effectiveness of many private-collective, publicly sanctioned, publicly man-
dated, and taxpayer-financed conventions, arrangements, and institutions.
Although finance would no doubt exist and bestow private and collec-
tive benefits without the particular social arrangements that have actually
emerged and evolved, there would most likely be significantly fewer such
benefits. Moreover, finance would most likely be significantly less efficient
and supportive of economic activity, wealth accumulation, growth, and
ultimately social prosperity. Is this not the case in many (if not most) devel-
oping countries in which financial systems have yet to reach a critical point
of effectiveness and efficiency?
In short, the enormous and pervasive private benefits of modern finance
and financial systems result from the existence of an effective financial sys-
tem that has long been understood and supported as a public good. This is
not meant to imply that all public policy involvement in private finance is
appropriate, beneficial, or acceptable. Nor should this be taken to mean
that all citizens benefit equally or have equal access to these private and
social benefits. But the social benefits are there for the taking, especially in
the more democratic societies with liberalized economies.
Although there now seems to be a consensus that many of the social
conventions and arrangements that have developed over time are essential
prerequisites for effective finance, this reflects a relatively new and modern

understanding of the role of finance. Less than 75 years ago, society’s mis-
management of both money and finance played an important and devas-
tating role in the Great Depression. More recently, some of these lessons
are being learned again, in both mature markets and in an increasing
number of emerging- and less-developed-market countries. For example,
in the aftermath of recent corporate scandals in some mature markets in
the early 2000s, improvements are being advocated and implemented—
with accounting standards and their enforcement and the efficacy of exist-
ing corporate governance procedures and accountability, for instance.
Likewise, as the result of recent financial crises in emerging-market coun-
tries, many of these social arrangements are being aggressively advocated
for adoption in both less advanced and least developed economies and
financial systems.
The obvious private and social benefits of finance as well as the some-
times disturbing events of the current era and their relationship to finan-
cial stability can be understood either to be the result of, or as at least
reflecting, important strengths and weaknesses of finance. As discussed in
Chapter 3, finance inherently embodies uncertainty and is associated with
several other market imperfections:
•Some financial services provide positive externalities while others pro-
vide negative externalities.
•Some financial services are public goods.
•There are information failures in the provision of financial services.
Financial contracts and markets are incomplete.
•Competition is not always perfectly balanced.
The practical import is that some market imperfections in finance can lead
to the underconsumption and underproduction of some socially desirable
financial activities, and the overconsumption and overproduction of some
socially undesirable ones. In addition, these market imperfections can, at
times, lead to the creation and accumulation of both economic and finan-
cial imbalances, which if not corrected could threaten financial stability.
As in other economic policy areas, it would seem reasonable to think
that private-collective and public actions could be designed and imple-
mented to address each source of market imperfection in finance, depend-
ing on how significant the efficiency losses associated with each might be.
For example, for cases in which the presence of a market imperfection
inhibits consumption and production of desirable financial activities, the
challenge would be to provide incentives to supply and consume more of
the activities that provide public benefits and positive externalities, that
tend to open up new markets, and that increase competition unless there
16
INTRODUCTION AND SUMMARY
are natural monopolies. For cases in which a market imperfection encour-
ages consumption and production of undesirable goods, the challenge
would be to minimize the production and consumption of financial activ-
ities that result from these market failures. In considering this approach,
the effectiveness of policies could be improved if they were designed and
implemented in a cohesive fashion so that a policy designed to eliminate
the negative impact of one kind of market imperfection does not offset the
benefits of a policy designed to deal with another.
Because tendencies to underproduce and overproduce financial activi-
ties exist simultaneously, financial-system policies would be more effective
if they strove to strike a socially optimal balance between maximizing the
net social benefits of the positive externalities and public goods and mini-
mizing the net social costs of the other market imperfections in finance. To
what extent such policy cohesiveness and coordination is actually achieved
in practice by countries or across borders is not clear. Striving to achieve
the social optimum will undoubtedly entail difficult choices, including
trading off some of the individual private benefits for the greater good, if
and when this can be justified.
The public policy discussion in Part I deals first with the efficiency loss
associated with market imperfections. However, each and every loss of effi-
ciency does not require intervention. The desirability or necessity of some
form of collective intervention is much clearer when a market imperfection
in finance leads to an inefficiency that poses a significant threat to financial
stability, because of the impact on either financial institutions or markets
or both. Unfortunately, the financial-system policy literature rarely makes
a clear distinction between sources of market imperfections that threaten
stability and those that do not. Likewise, no framework exists now either
for measuring the efficiency losses associated with market imperfections in
finance or for assessing the risks to financial stability associated with mar-
ket imperfections. These are some of the challenges in the period ahead, for
which an analytical framework for financial stability would be useful for
policy purposes. But this, too, is an enormous challenge.
In sum, while finance provides tremendous private and social benefits,
important aspects of finance are associated with market imperfections and
inherently hold the potential (although not necessarily a high likelihood)
for fragility, instability, systemic risk, and adverse economic consequences.
When private incentives and actions alone do not lead to an efficient pric-
ing and allocation of capital and financial risks, it is possible that some
combination of private-collective action and public policy could provide
incentives to encourage the private sector to obtain a more efficient and
desirable outcome.

Whether something can or should be done about this is the subject of
active debate, but practically depends on the social net benefits of taking
action. If the private and social benefits of taking action and providing
incentives outweigh the private and social costs, they are worthy of consid-
eration. A rule to consider, although difficult to implement, is that only poli-
cies that provide clear and measurable net benefits should be implemented.
This calculus most often involved both spatial and intertemporal trade-
offs. While immediate benefits might be associated with specific private-
collective or public sector policies, there may be greater future costs
associated with private market reactions and adjustments to the policies.
Examples include the costs of moral hazard and regulatory arbitrage.
Ultimately, it is a social and political decision whether private-collective
and public sector involvement and intervention are appropriate. These cost-
benefit, intertemporal, and social and political considerations are key rea-
sons that financial-system policies are so difficult to devise and implement
successfully.
In sum, this book addresses these and other closely related issues of
immediate relevance to global finance. The study is divided into three some-
what separable parts:
•Part I presents foundations for thinking about financial-stability
issues.
•Part II develops a working definition of financial stability and a broad
framework for monitoring, assessing, and ensuring it.
•Part III examines ongoing challenges to financial stability posed by
relatively recent structural financial changes, drawing on parts of the
framework presented.
Organization of the Book
The remainder of this chapter lays out the organization of the study in
somewhat more detail and summarizes some of its main findings.
The chapters in Part I provide a logical foundation for thinking about
financial-stability issues. Chapter 2 lays out the essence of modern
finance—the temporary transfer of the liquidity and payment services of
money (legal tender and its very close substitutes) in return for a promise
to return a greater amount of money to its original owner. The element of
human trust in financial relationships and contracts is the source of both
finances strengths (efficiency gains) and weaknesses (fragility). In princi-
ple, both these strengths and weaknesses can be defined and measured in
18
INTRODUCTION AND SUMMARY
terms of the manner in which finance does or does not enhance the effi-
ciency and effectiveness of other real economic processes, particularly
intertemporal economic processes such as production, wealth accumula-
tion, economic development and growth, and ultimately social prosperity.
In reality, precise measurement is extremely difficult if not impossible.
After developing and examining this simple logic—drawn from dis-
parate literatures—Chapter 3 applies some of the concepts from the eco-
nomics of the public sector to finance. The chapter identifies sources of
market imperfections in finance, justifies a role for both private-collective
and public policy involvement, and argues that both fiat money and
finance have the potential to convey significant positive externalities and
the characteristics of a public good.
Chapter 4 briefly clarifies what is meant by efficiency and stability from
an economic perspective. The implicit and practical import of this dis-
tinction is that not all market imperfections in finance may necessitate a
private-collective or public policy response; whether intervention is desir-
able or necessary depends on the size and importance of the imperfection
with regard to its impact on efficiency. While difficult to measure in prac-
tice, in principle the deviation from the efficient outcome should be part of
the decision to intervene. The chapter distinguishes between volatility,
fragility, and instability by drawing on the experience in the 1990s and early
2000s with market turbulence and country crises.
Part II then develops a broad policy-oriented framework for assessing
and safeguarding financial stability and for resolving problems when they
arise. The framework can be applied in a wide variety of existing ways of
managing financial system policies in various countries. Chapter 5 develops
a working definition of financial stability in terms of economic processes—
in principle, measurable ones—and identifies several practical implications
of the definition for financial-stability work. Based on this definition,
Chapter 6 proposes a generic framework for financial-stability monitoring,
assessment, and policy. The framework proposed is generic in three senses:
it encompasses all the important aspects of financial systems (institutions,
markets, and infrastructure); its implementation entails monitoring, ana-
lytical assessments, and policy adjustments when necessary; and it remains
at a general level that allows it to be an umbrella framework for most exist-
ing frameworks. This chapter also identifies remaining analytical and meas-
urement challenges. Chapter 7 discusses the role of central banks in
ensuring financial stability, which in many countries might be a natural or
special role.
Part III identifies and analyzes ongoing challenges to financial efficiency
and stability posed by relatively recent structural changes in national and
Organization of the Book
19
global finance. Each of these structural changes is no doubt improving
financial and, it is hoped, economic efficiency, but may also be posing new
risks or redistributing existing risks in ways that are poorly understood.
The chapters in this part of the study are sequenced so that they progress
from the general and broad in scope, to the more specific. Chapter 8
examines the stability implications of the globalization of finance and
financial risk for both national financial systems and the international
financial system. Chapter 9 examines the potential for instability in
national and global financial markets related to the growing reliance on
over-the-counter derivatives instruments and markets. Chapter 10 exam-
ines the implications for financial stability of the increased reliance on
efficiency-enhancing risk transfer mechanisms, and focuses in particular
on credit derivatives. Chapter 11 examines the supervisory, regulatory, and
perhaps systemic challenges raised by the now greater role of insurance
companies (and implicitly of other institutional investors) in financial and
capital market activities.
Chapter 12 collects the main challenges to financial stability that are dis-
cussed in the book and that are likely to be faced in the future. Each of the
areas identified in Part III taken separately, and certainly all of them taken
together, lead to the strong conclusion that further and continuous reforms
are desirable and should be aimed at striking a better balance between relying
on market discipline and relying on official or private-collective action. In
some countries—most of them advanced countries with mature markets—a
rebalancing toward relying more on market discipline is desirable. In other
countries—many of them with poorly developed markets—strong efforts
need to be made to improve the financial infrastructure through private-
collective and government expenditures and commitments and to target
the role of government to enhance the effectiveness and efficiency of mar-
ket mechanisms for finance. Specific areas where reforms are most needed
include
•a realignment of private market incentives, including within firms—
to improve internal governance at the board level, to improve man-
agement and risk controls, and to improve the alignment of incentives
at the board, management, and staff levels;
•a reevaluation of regulatory incentives and their consistency with pri-
vate market incentives—to reduce moral hazard;
•enhancements to disclosure by a wide range of financial and even
nonfinancial entities—to improve the potential for effective market
discipline and to improve private-collective and official monitoring
and supervision;
20
INTRODUCTION AND SUMMARY
improvements to market transparency—to reduce asymmetries in
markets and the tendency toward adverse selection;
an enhancement to legal certainty where it is still ambiguous, such as
with close-out procedures for swaps, credit derivatives, and other
complex structured financial instruments;
the development and implementation of comprehensive and appro-
priately targeted frameworks for monitoring, assessing, and safe-
guarding financial stability to better ensure financial stability and
restore it when this fails;
an increase in international cooperation and coordination in financial-
system regulation, surveillance, and supervision—to eliminate inter-
national gaps in information and analysis and to reduce, if not
eliminate, opportunities for regulatory arbitrage.
