ABSTRACT From 1953 to 1992, Japan reached the highest economic growth rates among industrialized countries. This performance was achieved despite two oil shocks and the endaka - the continuous rise of the yen vis-à-vis the dollar. This long-term growth cycle came to a sudden halt in early 90’s. Japanese economy stagnated while other industrialized countries continued growing. This was mainly due to the “economic bubkle” burst. From 1990 to 1992, the value of urban land and of the stock market index were cut to almost half. As a result, Japanese banks accumulated US$ 800 billion performing assets. This paper intends to analyse the Japanese “bubble economy crisis” and its long-term impacts on the Japanese economy, on its financial system and on its bilateral relations with the United States.

From 1978 to 1981, Kuwait’s two stock markets, one the conservatively regulated “official” market and the other the unregulated Souk al-Manakh, exploded in size, growing to the point where the amount of capital actively traded exceeded that of every other country in the world except the United States and Japan. A year later, the system collapsed in an instant, causing huge real losses to the economy and financial disruption lasting nearly a decade. This Commentary examines the emergence of the Souk, the simple financial innovation that evolved to solve its rapidly increasing need for liquidity and credit, and the herculean efforts to solve the tangled problems resulting from the collapse. Two lessons of Kuwait’s crisis are that it is difficult to separate the banking and unregulated financial sectors and that regulators need detailed data on the transactions being conducted at all financial institutions to give them the understanding of the entire network they must have to maintain financial stability. If Kuwaiti officials had had transaction-by-transaction data on the trades being made in both the regulated and unregulated stock markets, then the Kuwaiti crisis and its aftermath might not have been so severe.

The growing trend of interdependence between the international stock markets indicated the amalgamation of risk across borders that plays a significant role in portfolio diversification by selecting different assets from the financial markets and is also helpful for making extensive economic policy for the economies. By applying different methodologies, this study undertakes the volatility analysis of the emerging and OECD economies and analyzes the co-movement pattern between them. Moreover, with that motive, using the wavelet approach, we provide strong evidence of the short and long-run risk transfer over different time domains from Malaysia to its trading partners. Our findings show that during the Asian financial crisis (1997–98), Malaysia had short- and long-term relationships with China, Germany, Japan, Singapore, the UK, and Indonesia due to both high and low-frequency domains. Meanwhile, after the Global financial crisis (2008–09), it is being observed that Malaysia has long-term and short-term synchronization with emerging (China, India, Indonesia), OECD (Germany, France, USA, UK, Japan, Singapore) stock markets but Pakistan has the low level of co-movement with Malaysian stock market during the global financial crisis (2008–09). Moreover, it is being seen that Malaysia has short-term at both high and low-frequency co-movement with all the emerging and OECD economies except Japan, Singapore, and Indonesia during the COVID-19 period (2020–21). Japan, Singapore, and Indonesia have long-term synchronization relationships with the Malaysian stock market at high and low frequencies during COVID-19. While in a leading-lagging relationship, Malaysia’s stock market risk has both leading and lagging behavior with its trading partners’ stock market risk in the selected period; this behavior changes based on the different trade and investment flow factors. Moreover, DCC-GARCH findings shows that Malaysian market has both short term and long-term synchronization with trading partners except USA. Conspicuously, the integration pattern seems that the cooperation development between stock markets matters rather than the regional proximity in driving the cointegration. The study findings have significant implications for investors, governments, and policymakers around the globe.
