Scope of Investigation
A large body of evidence shows that previous crises
have had contagion effects on stock markets around
the world.
Empirical questions:
• Is there evidence of contagion of the Eurozone debt
crisis to other stock markets?
•What is the nature and the magnitude of such
contagion?

Related Literature
•King and Wadhwani (1990): contagion of 1987 U.S. market crash across Japan, London, and New York.
•Karolyi and Stulz (1996): large shocks to Japanese and U.S. stock market indices positively impact both the magnitude and the persistence of return correlations.
•Hamao et al. (1990): from New York to Tokyo and London, London to Tokyo, but not in other directions; more pronounced during the market crisis.
5
Related Literature
• Bae et al. (2003): contagion is more important in Latin American than in Asia, contagion from Latin America to other regions is more important than contagion from Asia, and that the U.S. is largely insulated from contagion from Asia.
• Baele (2005): contagion from the U.S. to a number of European equity markets during periods of high world market volatility.
• Samarakoon (2011): contagion of U.S. subprime crisis to other developed, emerging and frontier markets. Interdependence is driven more by U.S. shocks, while contagion is driven more by emerging market shocks. Except for Latin America, there is no contagion from U.S. to emerging markets. But there is contagion from emerging markets to the U.S.

Definition of Contagion
Excessive or incremental impact of shocks of one
market on another during a crisis relative to what is
expected during relatively tranquil times (Edwards,
(2000), Forbes and Rigobon (2002), Bekaert et al.
(2005))

Sample and Data
Daily stock returns (price changes) of 52 markets
•27 developed markets
•25 emerging markets
Daily sovereign bond yield of crisis countries
•Greece, Ireland, Portugal and Cyprus
Data source: Bloomberg
All returns are measured in U.S. dollar terms.
Sample period 11/01/2003 to 12/31/2012.
•Normal period: Nov 2003 to Oct 2009 (6 years) & Aug 2012 to Dec 2012 (5 months)
•Crisis period: Nov 2009 to July 2012 (33 months)

Methodology
VAR of stock returns vs. changes in bond yields and stock returns in crisis countries
•Overlapping markets
•Non-overlapping markets
• X is either
• change in the average daily bond yield of crisis countries (∆BYM) or
• average daily stock returns of crisis countries (RM)
• DUS is the U.S. subprime crisis dummy (1 during the period from 9/01/2008 to 03/09/2009 and zero otherwise) 9

Summary
Changes in sovereign bond yields of crisis countries impacted other equity markets positively in normal times and negatively during the eurozone crisis reflecting spillover of economic uncertainty.
Equity returns of crisis countries impacted other equity markets strongly positively during normal times and less positively during the debt crisis supporting the decoupling hypothesis.
Strong evidence of negative contagion from sovereign bond and equity markets of crisis countries to other equity markets.
The Asian markets do not show pervasive evidence of contagion from the eurozone debt crisis.
