The co-movement of stock markets in East Asia: Did the 1997–1998 Asian financial crisis really strengthen stock market integration?

This paper examines the integration and causality of interdependencies among seven major East Asian stock exchanges before, during, and after the 1997–1998 Asian financial crisis. For this purpose, we use daily stock market data from July 1, 1992 to June 30, 2003 in local currency as well as US dollar terms. The data reveal that the relationships among East Asian stock markets are time varying. While stock market interactions are limited before the Asian financial crisis, we find that Hong Kong and Singapore respond significantly to shocks in most other East Asian markets, including Shanghai and Shenzhen, during this crisis. After the crisis, shocks in Hong Kong and Singapore largely affect other East Asian stock markets, except for those in Mainland China. Finally, considering the role of the USA shows that it strongly influences stock returns in East Asia – except for Mainland China – in all periods, while the reverse does not hold true.     

East Asian equity markets,financial crises,and the Japanese currency

The paper studies the interactions between the US and four East Asian equity markets. The focus is on the change in the information structure/flow between these markets triggered by the 1997 Asian financial crisis. It is shown that the information structure during the crisis period is different from that in the non-crisis periods. While the US market leads the four East Asian markets before, during, and after the crisis, it is Granger-caused by these markets during the financial crisis period but not in the post-crisis sample. Further, in accordance with concerns reported in the market, the Japanese currency is found to affect these equity markets during the crisis period. The Japanese yen effect, however, disappears in the post-crisis sample. The Japanese currency effect is quite robust as it is found from both local currency and US dollar return data and in the presence of Japanese stock returns. J. Japanese Int.

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.     

东亚金融一体化的动态及其收益

近年来，东亚一系列区域金融合作引起了学术界对地区金融一体化现状和收益的极大兴趣。文章基于价格和数量的测度考察了东亚地区金融一体化的程度：抛补利差和股权溢价的β收敛结果表明，危机之前东亚金融市场的全球和区域一体化并行，但在近几年，区域一体化趋势更强劲，超过了全球一体化；金融引力模型的结果表明，东亚主要的跨境金融投资者的区域内金融资产持有量比金融引力模型预测的水平更大。此外，面板回归确定了较高的金融一体化作为更广泛的金融发展的关键组成部分，会显著降低东亚国家对发达国家的经常账户失衡，因此，区域层面的金融一体化可以作为加强东亚国家的增长来源和提高经济弹性的重要政策路径。     

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.

East Asian Export Competitiveness: New Measures and Policy Implications

This paper demonstrates the remarkable competitiveness of East Asian countries in world export markets for manufactures and develops some policy implications, both for developed and other developing economies. Using constant market share analysis, applied to data for exports from three East Asian countries–Korea, China and Indonesia–to markets in the industrially advanced economies (IAEs), it shows that East Asian countries have increased their share, not merely in IAE imports, but in total IAE market sales at the expense of exporters from other countries and of domestic IAE producers.     

Stock market uncertainty and uncovered equity parity deviation: Evidence from Asia

Recently, many empirical studies document that a country's stock market performance relative to the US and its local currency units per US dollar tend to move in opposite direction over the short run, also known as the uncovered equity parity (UEP) condition. However, those studies have applied only to advanced economies to date. This study conducted the same tests to a sample of 18 Asian economies. To one's surprise, we found that the UEP condition reverses its sign among Asian currencies. In addition, measures of stock market uncertainty are suggested as a potential driving force behind this UEP reversal for Asian economies. This surprising result suggests that there might be other mechanisms behind the joint dynamics of equity and currency returns than the portfolio rebalancing caused by incomplete foreign exchange risk hedging. The reasoning is that Asian foreign exchange (FX) markets are even more subject to incomplete foreign exchange risk hedging. Thus, one should expect even stronger UEP evidence from Asian currency markets if the portfolio rebalancing mechanism was the only force at play.     

The impact of data snooping on the testing of technical analysis: An empirical study of Asian stock markets

The primary aim of this study is to investigate the validity and predictability of technical analysis in eight Asian equity markets. We employ the bootstrap tests of White (2000) and Hansen (2005) to determine whether any superior trading rule is found to exist amongst the ‘universe’ of technical trading rules identified by Sullivan et al. (1999). We use these powerful bootstrap tests to ascertain the profitability of technical analysis, along with two institutional adjustments for non-synchronous trading and transaction costs. The empirical results indicate that these three elements, data snooping, non-synchronous trading and transaction costs, have significant impact on the overall performance of technical analysis; indeed, the results for these eight Asian stock markets support the efficient market hypothesis, demonstrating that the generation of economic profits through the use of technical analysis is extremely unlikely with these particular markets.     

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.     

Output volatility of five crisis-affected East Asia economies

A decade has passed since the Asian financial crisis (AFC) in 1997, and attention is drawn to the output performance of the crisis-affected economies in East Asia. Using the Hodrick–Prescott (HP) filter, this paper examines the growth volatility of GDP, its components and the stock market of five East Asia economies of Japan, Singapore, South Korea, Chinese Taipei and Hong Kong Special Administrative Region (SAR). Empirical evidences based on quarterly data show that output volatility for both Singapore and South Korea has increased after the AFC. For the GDP components, trade is a major factor in lowering GDP volatility in Chinese Taipei. The Hong Kong SAR economy has experienced an increase/decrease in the volatility of investment/private consumption. Among the five East Asia economies, government intervention is obvious in Singapore. The stock markets in both Hong Kong SAR and Chinese Taipei showed stronger ability in absorbing shocks.     

Influence of ADB Bond Issues and US Bonds on Asian Government Bonds*

This article examines whether there is a correlation between the government bond markets of Asian countries and those of the USA, and whether the efforts of international organizations to improve bond markets have had any effect in East Asia. Because the sizes of the government bond markets are larger than those of the corporate bond markets in East Asia, the present paper uses the daily data of government bonds to examine two questions: whether government bond yields in Hong Kong, Singapore and Thailand correlate with US government bond yields, and whether bonds in these Asian countries are influenced by ADB bond issues. The present study analyzes these issues by demonstrating the fluctuations in bond yields and carrying out an estimation using the exponential generalized autoregressive conditional heteroskedasticity model. The results substantiate that there is indeed a correlation between Asian and US bond markets, and that ADB bond issuance in local markets can contribute to the development of Asian bond markets.     

Financing investment in East Asia: Regional or global savings?

This paper investigates the extent to which domestic investment in East Asian countries is financed by domestic, (East Asian) regional and global savings in order to infer the relative importance of regional vs. global capital markets in East Asia. Panel regression results show that regional saving in East Asia plays a much more important role than global saving in financing investment in the region. The results suggest that global capital flows, despite its huge volume in East Asia, does not contribute to proper investment financing. The results also show that Japanese saving has significant effects on regional investment but Chinese saving does not.     

Return and volatility spillovers among the East Asian equity markets

This article examines the extent of contagion and interdependence across the East Asian equity markets since early 1990s and compares the ongoing crisis with earlier episodes. Using the forecast error variance decomposition from a vector autoregression, we derive return and volatility spillover indices over the rolling sub-sample windows. We show that there is substantial difference between the behavior of the East Asian return and volatility spillover indices over time. While the return spillover index reveals increased integration among the East Asian equity markets, the volatility spillover index experiences significant bursts during major market crises, including the East Asian crisis. The fact that both return and volatility spillover indices reached their respective peaks during the current global financial crisis attests to the severity of the current episode.     

Financial integration and consumption risk sharing in East Asia

This paper estimates the degree of consumption risk sharing and analyzes the channels of consumption risk sharing among the 10 East Asian countries. Estimation results show that a bulk of cross-sectional variance of GDP, about 80 percent, is not smoothed within the region which suggests that the degree of consumption risk sharing is far from complete and very low in the region. Capital markets play a minimal role and credit markets provide a positive but limited role. These results imply that the market channels do not function well in smoothing idiosyncratic output shocks. To be consistent, we also found that the potential welfare gains from consumption risk sharing within East Asia are quite large. Compared to the OECD countries, the degree of risk sharing achieved is lower and the potential gains are larger in the East Asian countries, but the degree of risk sharing and the potential gains are similar in relatively more developed East Asian countries.     

Empirical study on intra-regional bond investment: an application to East Asia

Since the 1997 Asian financial crisis, bond market development has been one of the central pillars of financial cooperation in East Asia, with concerted efforts made by the East Asian economies to integrate regional bond markets. As a result, aggregate intra-regional bond investment expanded from US$49.56 billion in 2003 to US$352.18 billion in 2017. This paper examines the pattern and determinants of intra-regional bond investment in East Asia. We analyse regional foreign holdings of long-term and short-term bonds in eight East Asian economies. Bond market size turns out to be the main concern of regional foreign investors participating in East Asian long-term bond markets. This analysis also highlights the importance of bond issuance and bond yield volatility in attracting regional foreign short-term bond investment. Therefore, initiatives to improve regional bond market development may be crucial to stimulating intra-regional bond investment and in turn enhance East Asian financial stability.

Changes in the socialist countries: Contents and prospects

Abstract

This paper examines volatility transmission and conditional correlations behaviour between the US and the Asian stock markets considering the effect of the Global Financial crisis. One Asian mature market and 10 emerging markets are included in the sample. To carry out the analysis, we use a multivariate asymmetric GARCH model. Results show that there exists volatility transmission between the US and the Asian markets. Moreover, it is found that, after the crisis, volatility transmission patterns have barely changed. Finally, results suggest that the lower the country‘s level of development, the lower the correlation with the USA.     

Impact of the US Economic Crisis on East Asian Economies： Production Networks and Triangular Trade through Chinese Mainland

This paper investigates the impact of the 2008 economic crisis on industries in East Asia. It attempts to identify the transmission mechanism and the magnitude of the impact of the crisis on industries in East Asia using the updated Asian international input–output table for 2008. The analyses reveal that the crisis significantly affected industrial output of the nine East Asian economies included in the present study. The economies that are deeply involved in production networks were affected most seriously. Our analyses also show that the impact was transmitted to East Asian industries through triangular trade, in which Chinese mainland imports parts and components from neighboring East Asian economies and then exports final products to the US and EU markets. Although such intricate production networks have improved the competitiveness of East Asian economies, they have also increased vulnerability to external shocks.     

Examining Stock Volatility in the Segmented Chinese Stock Markets: A SWARCH Approach

Abstract

This study adopts the SWARCH model to examine the volatile behavior and volatility linkages among the four major segmented Chinese stock indices. We find strong evidence of a regime shift in the volatility of the four markets, and the SWARCH model appears to outperform standard generalized autoregressive conditional heteroskedasticity (GARCH) family models. The evidence suggests that, compared with the A-share markets, B-share markets stay in a high-volatility state longer and are more volatile and shift more frequently between high- and low-volatility states. In addition, the relative magnitude of the high-volatility compared with that of the low-volatility state in the B-share markets is much greater than the case in the two A-share markets. B-share markets are found to be more sensitive to international shocks, while A-share markets seem immune to international spillovers of volatility. Finally, analyses of the volatility spillover effect among the four stock markets indicate that the A-share markets play a dominant role in volatility in Chinese stock markets.
