Testing contagion of the 1997–98 crisis in Asian stock markets with structural breaks and incubation periods

This study tests for the existence of financial contagion, using a method that allows an incubation period before contagion takes effect. We define contagion as an increase in cross-market linkages following shocks. With daily data on Asian stock markets during the 1997–98 crisis, we find significant upward shifts in the linkages between the Asian markets of both crisis and non-crisis countries. The upward shifts are maintained even after controlling for heteroskedasticity and common world and regional factors, providing strong evidence for financial contagion.     

High‐Frequency Contagion of Currency Crises in Asia*

Using daily data from the Asian currency crisis, the present paper examines high‐frequency contagion effects among six Asian countries. The ‘origin’ (of exchange rate depreciation, or decline in stock prices) and the ‘affected’ (currencies, or stock prices) in the daily spillover relationship were defined and identified. Indonesia is found to be the main origin country, affecting exchange rates of other countries. Contrary to conventional wisdom, evidence of high‐frequency crisis spillover from the Thai exchange rate to other currencies was weak at best. There exists a high‐frequency contagion in stock markets among East Asian countries. Contagion coefficients are positively correlated with trade indices, indicating that investors lower their financial assessment of a country that has trade linkage to a crisis origin country within days, if not hours, of a shock.     

Why are currency crises contagious? A comparison of the Latin American Crisis of 1994–1995 and the Asian Crisis of 1997–1998

Why Are Currency Crises Contagious? A Comparison of the Latin American Crisis of 1994–1995 and the Asian Crisis of 1997–1998.—This paper analyzes three channels through which currency crises are transmitted between countries: contagion based on unsustainable economic fundamentals; contagion resulting from herding behaviour in financial markets; contagion induced by close trade integration. The presented model that links currency crises with these three types of contagion is employed to analyze the transmission of the Mexican crisis in 1994–1995 and the Thai crisis in 1997 to other emerging economies. The empirical results show that, first, the most important contagion channels were based on close financial and trade integration rather than on the weakness of macroeconomic fundamentals. Second, the vulnerability to capital flow reversals and weak financial sectors made countries particularly prone to a currency crisis, while external imbalances and currency misalignments were much less important.

Estimating time-varying currency betas with contagion: New evidence from developed and emerging financial markets

This paper examines the conditional time-varying currency betas from five developed and six emerging financial markets with contagion and spillover effects. We employ a trivariate asymmetric BEKK-type GARCH-in-Mean (MGARCH-M) approach to estimate the time-varying conditional variance and covariance of returns of stock market index, the world market portfolio and bilateral exchange rate between the US dollar and the local currency. The results show that the world market and currency risks are not only priced in the stock markets, but also time-varying. It is found that currency betas are much more volatile than the world market betas, and currency betas in the emerging markets are more volatile than those in the developed markets. We find empirical evidence of contagion effect and spillovers between stock market and foreign exchange market during the recent global financial crisis, and the effect is stronger in the emerging markets than that in the developed markets. Two applications are provided to illustrate the usefulness of time-varying currency betas.     

The current global financial crisis: Do Asian stock markets show contagion or interdependence effects?

In the framework of the current global economic crisis, a pertinent question is whether the world economies are suffering from contagion or interdependence effects. With its origins in the US sub-prime mortgage market crisis starting at the end of 2007, when a loss of confidence by investors in the value of securitized mortgages resulted in a liquidity crisis, hard-hitting the banking system and rapidly spreading into the financial markets, the effects of the crisis were automatically reflected in the rest of the world economies. These effects become more severe as the rest of the world is facing economic and financial instability. Therefore, the American shock can be seen as the trigger that revealed the other economies’ own financial problems. The main finding of this paper shows that the US stock markets are not generating contagious effects into the Asian stock markets. However, strong evidence of volatility transmission derived from these economies’ interlinkages has been detected.     

Is the COVID-19 pandemic more contagious for the Asian stock markets? A comparison with the Asian financial,the US subprime and the Eurozone debt crisis

The ongoing COVID-19 pandemic has sent shock waves across the global stock markets. Several financial crises in the past too have had a global impact with their reach extending beyond the country of origin. The current study compares the contagion effect of four such crises viz. the Asian financial crisis, the US subprime crisis, the Eurozone debt crisis, and the currently ongoing Covid-19 crisis on Asian stock markets to understand which of these has had the most severe impact. It finds that among all the four crises, the US subprime crisis has been the most contagious for the Asian stock markets. The study also highlights the difference between severities of a liquidity crisis versus a real crisis and identifies the markets that remained insulated from all these crises, a finding which will be useful for portfolio managers in devising their asset allocation.     

Foreign Exchange Market Contagion in the Asian Crisis: A Regression-Based Approach

This paper investigates whether, during the Asian crisis, contagion occurred from Thailand to the other crisis countries through the foreign exchange market, and, if so, determines the contribution of this contagion to the crisis. More specifically, we examine whether the effect of the exchange market pressure (EMP) of Thailand, the origin of the crisis, on the EMP of four Asian crisis countries increased during the crisis. Instead of measuring contagion by the commonly used correlation coefficients, we apply regression analysis. To control for the impact of macroeconomic fundamentals, we construct a time-varying indicator measuring the fragility of each economy. Additionally, we control for spillovers and common external shocks. We find evidence of contagion from Thailand to Indonesia and Malaysia, with 13 and 21 percent of the pressure on the respective currencies attributable to that contagion. For Korea and the Philippines there is no evidence of contagion from Thailand. JEL no. F30, F31, G15     

Efficiency,Cointegration and Contagion in Equity Markets: Evidence from China,Japan and South Korea*

This paper empirically examines whether three East Asian stock markets, namely, those of China, Japan and South Korea, are individually and/or jointly efficient, and whether contagion exists between the cointegrated markets. While individual market efficiency is examined through testing for the random walk hypothesis, joint market efficiency is examined through testing for cointegration and contagion. The present study finds that the hypothesis of individual market efficiency is strongly rejected for the Chinese stock market, but not for the Japanese and the South Korean stock markets. However, when testing for cointegration, market efficiency is strongly rejected for all these markets. We take a simple case of contagion and find that although there is a long‐term relationship among the three markets, the contagion hypothesis cannot be rejected only between Japanese and South Korean stock markets, indicating short‐run portfolio diversification benefits from these two markets.     

Cross-country causes and consequences of the 2008 crisis: Early warning

This paper models the causes of the 2008 financial crisis together with its manifestations, using a Multiple Indicator Multiple Cause (MIMIC) model. Our analysis is conducted on a cross-section of 107 countries; we focus on national causes and consequences of the crisis, ignoring cross-country “contagion” effects. Our model of the incidence of the crisis combines 2008 changes in real GDP, the stock market, country credit ratings, and the exchange rate. We explore the linkages between these manifestations of the crisis and a number of its possible causes from 2006 and earlier. We include over sixty potential causes of the crisis, covering such categories as: financial system policies and conditions; asset price appreciation in real estate and equity markets; international imbalances and foreign reserve adequacy; macroeconomic policies; and institutional and geographic features. Despite the fact that we use a wide number of possible causes in a flexible statistical framework, we are unable to link most of the commonly cited causes of the crisis to its incidence across countries. This negative finding in the cross-section makes us skeptical of the accuracy of “early warning” systems of potential crises, which must also predict their timing.     

次贷危机后的中、美股市联动性分析

采用协整分析和向量自回归(VAR)模型,对上证综指和美国道指之间的联动性进行了实证研究。研究结果发现:在股权分置改革以后至金融危机发生以前,中、美两国股市存在联动关系;危机以后,中、美两国股市相对独立。从整体上看,截至目前为止中、美两国股市无显著的长期动态均衡关系,中国股市也无力引领美股。     

Herding behaviour in the Chinese and Indian stock markets

The existence of herding behaviour challenges the validity of the “efficient market hypothesis”. This study examines herding behaviour in the Chinese and Indian stock markets; our findings suggest that herding behaviour exists in both. The level of herding depends on market conditions. In the Chinese market, herding behaviour is greater when the market is falling and the trading volume is high. On the other hand, in India the study finds that it occurs during up-swings in market conditions. Herding behaviour is more prevalent during large market movements in both markets. In relative terms, a lower prevalence of herding behaviour was detected in the Indian stock market.     

INDONESIA'S ECONOMIC CRISIS: CONTAGION AND FUNDAMENTALS

The severe and unanticipated economic downturn in Indonesia mirrored the regional economic fallout following the 1997 financial crisis. Although it is likely that the crisis in neighboring countries had an adverse impact on Indonesia, the issue has so far received little attention. This paper examines whether contagion from the economic crisis in Thailand triggered the crisis in Indonesia. Evidence of such a contagion is revealed, and the contagion was possibly exacerbated by increasing imbalances in the Indonesian economy. The paper also examines the channels through which the economic difficulties of Thailand might have been transmitted to Indonesia. Investors’behavior, rather than real links, is identified as one important channel for the contagion.     

German,US and Central and Eastern European Stock Market Integration

This paper examines the long-term linkages between seven Central and Eastern European (CEE) emerging stock markets and two developed stock markets, namely the German and the US markets. The stability of the long-run relationships is studied using recursive cointegration analysis. The results reveal that the financial linkages between the CEE markets and the world markets increased with the beginning of the EU accession process. Furthermore, the application of the Gonzalo and Granger (J Bus Econ Stat 13:27–35, 1995) methodology indicates that the examined stock markets are partially integrated, while there is also evidence that the emerging stock markets of Central and Eastern Europe except for Estonia together with the German and the US stock markets, have a significant common permanent component, which drives this system of stock exchanges in the long run. Finally, it is worthwhile to note that the global financial crisis of 2007–2009 caused a slowdown in the convergence process. In addition we find evidence that the Slovenian stock market exhibits a moderate increase in the transitory component and this may be attributed to the Slovenian full membership in the euro area.     

Contagion or Real Linkages？ Some Evidence from China＇s Emerging Parallel Markets

This paper empirically tests the existence of contagion using data on China's five parallel markets with different entry barriers for foreign capital. Taking the 1997 stock market crash as our experiment and using data on A, B and H shares, red chips and American depository receipts, the present paper tests whether these China‐backed market returns respond differently to foreign shocks during the pre‐1997 and post‐1997 crash period. Evidence suggests that the contagion effects are stronger in markets with fewer entry barriers. An important implication of our findings is that countries vulnerable to contagion could be justified to impose some limits on capital flows.     

Currency crisis and contagion: evidence from exchange rates and sectoral stock indices of the Philippines and Thailand

This paper analyzes empirically the recent Asian financial crisis by using high-frequency data of exchange rates and stock indices of the Philippines and Thailand. With time-series techniques, this study confirms that benchmark stock indices often fail to provide valuable insights into currency crises, but there is evidence that developments in some sectoral indices—including those of banking and financial sectors—seem to have caused upward pressure on exchange rates. Our evidence therefore confirms the importance of financial markets as a transmission channel during the currency crisis period.     

Multivariate contagion and interdependence

This paper proposes a multivariate test to measure the statistical and economic significance of contagion through analysis of extreme unobserved common shocks. Contagious episodes are endogenously determined with no need, but the possibility, to specify the source country. Application to a panel of equity returns during the Asian crisis of 1997–1998 finds that interdependencies are substantially more important than contagion. However, the periods of contagion evident show that it is short-lived, split between positive and negative movements and reverses quickly. In comparison to other Asian crisis countries, Hong Kong is the main driver of contagion in the crisis. The proposed methodology and the empirical findings provide a more detailed picture of contagion than commonly applied tests.     

亚太地区股票市场的联动程度——基于次级贷冲击的研究

本文从长期关系、短期作用和方差分解方面,分析了次级贷危机前后亚太股市的联动程度。首先,协整检验表明,亚太股市存在长期均衡关系,但这种关系在次级贷危机前后发生了明显的结构转变。其次,Granger非因果检验表明,亚太股市在次级贷危机后,市场间短期作用大大加强。再次,我们定义了单个市场联动程度判断准则,并且结合方差分解发现,亚太地区股市在次级贷危机后单个市场独立性显著降低。总体而言,亚太地区股市在次级贷危机之后联动程度进一步加强,支持弱分割市场理论;美国股市是地区股市领导者;日本股市变化最大,次级贷危机后,市场独立性变得最弱;中国大陆股市也不断融入区域市场。建议政府和投资者对于本国(本地区)之外的实体经济和股市风险都要密切关注。

Do US macroeconomic conditions affect Asian stock markets?

The aim of this paper is to examine the impact of US macroeconomic conditions—namely, exchange rate and short-term interest rate—on the stock markets of seven Asian countries (China, India, the Philippines, Malaysia, Singapore, Thailand, and South Korea). We use daily data for the period 2000–2010. We divide the sample into a pre-crisis period (pre-August 2007) and a crisis period (post-August 2007). We find that, in the short-run, the interest rate has a statistically insignificant effect on returns for all countries, except for the Philippines in the crisis period. On the other hand, except for China, regardless of the crisis, depreciation has a statistically significant and negative effect on returns. When the long-run relationship among the variables is considered, for five of the seven countries (India, Malaysia, the Philippines, Singapore, and Thailand), while there is cointegration in the pre-crisis period, in the crisis period there is no such relationship, implying that the financial crisis has actually weakened the link between stock prices and economic fundamentals.
