The following symbols have been used throughout this volume:
. . . to indicate that data are not available;
— to indicate that the fi gure is zero or less than half the fi nal digit shown, or that the
item does not exist;
– between years or months (for example, 1997–99 or January–June) to indicate the
years or months covered, including the beginning and ending years or months;
/ between years (for example, 1998/99) to indicate a fi scal or fi nancial year.
“Billion” means a thousand million; “trillion” means a thousand billion.
“Basis points” refer to hundredths of 1 percentage point (for example, 25 basis points
are equivalent to !/4 of 1 percentage point).
“n.a.” means not applicable.
Minor discrepancies between constituent fi gures and totals are due to rounding.
As used in this volume the term “country” does not in all cases refer to a territorial
entity that is a state as understood by international law and practice. As used here, the
term also covers some territorial entities that are not states but for which statistical data
are maintained on a separate and independent basis.

PREFACE
The Global Financial Stability Report (GFSR) assesses key issues in global fi nancial market develop-
ments with a view to identifying systemic vulnerabilities. By calling attention to fault lines in the global
fi nancial system, the report generally seeks to play a role in preventing crises and, when they do occur,
helping to mitigate their effects and offer policy advice, thereby contributing to global fi nancial stabil-
ity and to sustained economic growth of the IMF’s member countries.
The analysis in this report has been coordinated in the Monetary and Capital Markets (MCM)
Department under the general direction of Jaime Caruana, Counsellor and Director. The project has
been directed by MCM staff Peter Dattels and Laura Kodres, Division Chiefs; and Brenda González-
Hermosillo and L. Effi e Psalida, Deputy Division Chiefs. It has benefi ted from comments and sugges-
tions from Jonathan Fiechter and Christopher Towe, both Deputy Directors, and Mahmood Pradhan,
Assistant Director.
Primary contributors to this report also include Sergei Antoshin, Sean Craig, Phil de Imus, K ristian
Hartelius, Heiko Hesse, John Kiff, Ulrich Klueh, Rebecca McCaughrin, Paul Mills, Ken Miyajima,
Michael Moore, Christopher Morris, Mustafa Saiyid, Kenneth Sullivan, and Christopher Walker. Other
contributors include Kristian Flyvholm, Marina Moretti, Miguel Segoviano, Tao Sun, and Ian Tower.
Nathaniel Frank provided empirical modeling support. Martin Edmonds, Oksana Khadarina, Yoon
Sook Kim, Narayan Suryakumar, and Kalin Tintchev provided analytical support. Caroline Bagworth,
Shannon Bui, Christy Gray, and Aster Teklemariam were responsible for word processing. David Ein-
horn of the External Relations Department edited the manuscript and coordinated production of the
publication.
This particular issue draws, in part, on a series of discussions with accountancies, banks, securities
fi rms, asset management companies, hedge funds, auditors, credit rating agencies, fi nancial consul-
tants, and academic researchers, as well as regulatory and other public authorities in major fi nancial
centers and countries. The report refl ects information available up to March 21, 2008.
The report benefi ted from comments and suggestions from staff in other IMF departments, as well
as from Executive Directors following their discussion of the Global Financial Stability Report on March
26, 2008. However, the analysis and policy considerations are those of the contributing staff and should
not be attributed to the Executive Directors, their national authorities, or the IMF.
