Securitization of the agricultural commodity market has accelerated since the beginning of the 21st century, particularly in the times of financial market uncertainty and crisis. Sugar belongs to the group of important agricultural commodities. The global financial crisis and the COVID-19 pandemic has caused a substantial increase in the stock market volatility. Moreover, the novel coronavirus hit both the sugar market’s supply and demand side, resulting in sugar stock changes. The paper aims to assess potential structural changes in the relationship between sugar prices and the financial market uncertainty in a crisis time. In more detail, using sequential Bai–Perron tests for structural breaks, we check whether the global financial crisis and the COVID-19 pandemic have induced structural breaks in that relationship. Sugar prices are represented by the S&P GSCI Sugar Index, while the S&P 500 option-implied volatility index (VIX) is used to show stock market uncertainty. To investigate the changes in the relationship between sugar prices and stock market uncertainty, a regression model with a sequential Bai–Perron test for structural breaks is applied for the daily data from 2000–2020. We reveal the existence of two structural breaks in the analysed relationship. The first breakpoint was linked to the global financial crisis outbreak, and the second occurred in December 2011. Surprisingly, the COVID-19 pandemic has not induced the statistically significant structural change. Based on the regression model with Bai–Perron structural changes, we show that from 2000 until the beginning of the global financial crisis, the relationship between the sugar prices and the financial market uncertainty was insignificant. The global financial crisis led to a structural change in the relationship. Since August 2008, we observe a significant and negative relationship between the S&P GSCI Sugar Index and the S&P 500 option-implied volatility index (VIX). Sensitivity analysis conducted for the different financial market uncertainty measures, i.e., the S&P 500 Realized Volatility Index confirms our findings.

This study examines the return and volatility transmission between gold and nine emerging Asian Stock Markets during the global financial crisis and the Chinese stock market crash. We use the VAR-AGARCH model to estimate return and volatility spillovers over the period from January 2000 through June 30, 2018. The results reveal the substantial return and volatility spillovers between the gold and emerging Asian stock markets during the global financial crisis and the Chinese stock market crash. However, these return and volatility transmissions vary across the pairs of stock markets and the financial crises. Besides, we analyze the optimal portfolios and hedge ratios between gold and emerging Asian stock markets during all sample periods. Our findings have important implications for effective hedging and diversification strategies, asset pricing and risk management.

Real estate divestitures and acquisitions (D&A) are conducted as part of corporate restructuring. This study aims to fill the knowledge gap on abnormal stock market returns (AR) toward D&A activities during the Global Financial Crisis (GFC) in a developing country. Malaysian listed non-real estate companies that conducted D&A during the GFC are used as sample. Event study is applied to determine AR surrounding D&A announcements within (-10day, +10day) event window. Results for both D&A announcements shows insignificant AR on and around announcement date (-1 to +1). For pre-announcement, divesting (acquiring) companies obtain negative (positive) AR, signifying that the market does not favor (favor) divestitures (acquisitions) due to leakage of information. The outcome of post-announcement proves that divesting companies continue to experience negative ARs, although most divesting companies were paid premium prices. However, acquiring companies experience significant and negative post-announcement AR. This is probably due to the price premium which most acquiring companies paid exceeding valuation for their acquisitions. In summary, the market disapproves divestitures in general and acquisitions of real estate assets exceeding their valuations during economic recessions.

This paper empirically investigates the contagion effects of the Global Financial Crisis (2007-2009) from the financial sector to the real economy by examining nine sectors of US and developed European region. We provide a regional analysis by testing stock market contagion on the aggregate level and the sector level, on the global level and the domestic/regional level. Results show evidence of global contagion in US and developed European aggregate stock market indices and all US sector indices, implying the limited benefits of portfolio diversification. On the other hand, most of the European regional sectors seem to be immune to the adverse effects of the crisis. Finally, all non-financial sectors of both geographical areas seem to be unaffected by their domestic financial systems. These findings have important implications for policy makers, investors and international organizations.

This paper investigates the risk contribution of 29 industrial sectors to the China stock market by using one-factor with Durante generator copulas (FDG) and component expected shortfall (CES) analyses. Risk contagion between the systemically most important sector and other sectors is examined using a copula-based ∆CoVaR approach. The data cover the 2008 global financial crisis and the beginning of the COVID-19 pandemic. The empirical results show that the banking sector contributed most to systemic risk before and during the global financial crisis. Nonbank finance became equally important in 2020, and the COVID-19 pandemic promoted the position of the computer and pharmaceuticals sectors. The spillover effect diminishes over time, but there remains risk contagion between sectors. The risk spillover trend is consistent with that of systemic risk.
