Assessing Financial Risk Spillover and Panic Impact of Covid-19 on European and Vietnam Stock market.

This study examined the influence of tail risks on global financial markets, which aids in better understanding of the emergence of COVID-19. This study looks at the global and Vietnamese stock markets impacted by the COVID-19 pandemic to identify systemic emergencies. Risk dependent value (CoVaR) and Delta link VaR are two important tail-related risk indicators used in Conditional Bivariate Dynamic Correlation (DCC) (CoVaR). The empirical findings demonstrate that when COVID-19's worldwide spread widens, the volatility transmission of systemic risks across the global stock market and multiple exchanges shifts and becomes more relevant over time. At the time of COVID-19, the world industrial market was larger than the Vietnamese stock market, and the Vietnamese stock market posed a lesser danger to the global market. A closer examination of the link between the Vietnam value-at-risk (VaR) range index sample and the world stock index indicates a significant degree of downside risk integration in key monetary systems, particularly during the COVID-19 era. Our study findings may help regulators, politicians, and portfolio risk managers in Vietnam and worldwide during the unique moment of uncertainty created by the COVID-19 epidemic.

Does external debt as a new determinants of fiscal policy influence sustainable economic growth: implications after COVID-19

External debt correlation and the sustainable economic development pathway within the South Asian sub-region is analysed in this research paper. The longitudinal root-analysis, the pooled ordinary least square, quantile estimation, and output estimation were utilized to evaluate the data obtained from the World Bank Development Indicators for the period of 2000–2018. We discovered that total external debt and external debt services affect 39% plus 31%, respectively, after the robust regression analysis was carried out. Besides that, the findings demonstrate direct expansionary impacts of fiscal policy crosswise in developing economies within the study timeframe. Remarkably, the advancements in state establishments encourage the “gathering impact” of fiscal policy implementation. The findings depict that the entire circumstances set a stiffer restraint on public expenditure, indicating a self-losing fiscal austerity situation which entails the impact of the company’s liabilities. Inversely, the unrestrained countercyclical policy bars the knock-on impact of external problems, resulting in an improved economic system activity performance as well as decreasing the probability of economic predicaments after COVID-19.

How COVID-19 induced panic on stock price and green finance markets: global economic recovery nexus from volatility dynamics.

This paper investigates the effect of different categories of essential COVID-19 data from 2020 to 2021 towards stock price dynamics and options markets. It applied the hypothetical method in which investors develop depression based on the understanding suggested by various green finance divisions. Furthermore, additional elements like panic, sentiment, and social networking sites may impact the attitude, size, and direction of green finance, subsequently impacting the security prices. We created new emotion proxies based on five groups of information, namely COVID-19, marketplace, lockdown, banking sector, and government relief using Google search data. The results show that (1) if the proportional number of traders' conduct exceeds the stock market, the effect of sentimentality indexes on jump volatility is expected to change; (2) the volatility index component jump radically increases with the COVID-19 index, city and market lockdown index, and banking index; and (3) expanding the COVID-19 index gives rise to the stock market index. Moreover, all indexes decreased in jump volatility but only after 5 days. These findings comply with the hypotheses proposed by our model.
