Highlights We investigate the tail-dependency networks of 51 financial assets. The extreme quantile coherency is estimated using the quantile cross-spectral analysis and the tail-dependency network is built using the force-directed layout algorithm. The Covid-19 pandemic asymmetrically increases the network density, with stronger effects in the left-tail dependencie of asset returns. The cross-asset tail-dependency of equity, currency and commodity increases considerably, implying a higher degree of tail contagion effects. Bitcoin and US Treasury bonds are disconnected from both tail-dependency networks, suggesting their safe-haven characteristics.

PurposeThe authors provide a comprehensive study on systemic risk of the banking sectors in the ASEAN-6 countries. In particular, they investigate the systemic risk dynamics and determinants of 49 listed banks in the region over the 2000–2018 period.Design/methodology/approachThe authors employ the market-based SRISK measure of Brownlees and Engle (2017) to investigate the systemic risk of the ASEAN-6's banking sectors.FindingsThe authors find that the regional systemic risk fluctuates significantly and currently at par or higher level than that of the recent global financial crisis. Systemic risk is generally associated with banks that have bigger size, more traditional business models, lower quality in their loan portfolios, less profitable and with lower market-to-book values. However, these relationships vary significantly between ASEAN countries.Research limitations/implicationsThe research focuses on the systemic risk of ASEAN-6 countries. Therefore, the research results may lack generalizability to other countries.Practical implicationsThe authors’ empirical evidence advocates the use of capital surcharges on the systemically important financial institutions. Although the region has been pushing to higher financial integration in recent years, the authors encourage the regional regulators to account for the idiosyncratic characteristics of their banking sectors in designing effective macroprudential policy to contain systemic risk.Originality/valueThis paper provides the first study on the systemic risk of the ASEAN-6 region. The empirical evidence on the drivers of systemic risk would be of interest to the regional regulators.

This paper concentrates on examining the impact of the credit boom (2007)(2008)(2009)(2010) on the soundness of the commercial banking system in Vietnam by using qualitative and quantitative methods. The results show that the credit boom in the period 2007-2010 had made Vietnam's banking system face many uncertainties such as difficulties in liquidity, increased non-performing loans... The influence of the credit boom on Vietnam's banking system is assessed on basic aspects such as asset quality, profitability, liquidity, capital adequacy... The quantitative analysis of the impact is made through the regression model using variables that show the characteristic of individual commercial bank and the volatility of the economy. The data is collected from 18 commercial banks in Vietnam in the period from 2005 to 2013, taken from the database BankScope and supplemented by information from the annual financial reports of the banks. Finally, in order to avoid the possibility of credit booms in the future and their effects on bank soundness in Vietnam, some recommendations related to credit growth are proposed for the authorities and the commercial banks.
