The empirical results show that listed firms across these countries, financial and non-financial firms alike, experience significant increase in conditional correlations between their stock returns. However, the magnitude of increase in these correlations is considerably higher for financial firms during the COVID-19 outbreak, indicating the importance of their role in financial contagion transmission. They also show that optimal hedge ratios increase significantly in most cases, implying higher hedging costs during the COVID-19 period.EnglishCOVID–19Ffinancial contagionSpillover indexFinancial firmsNonfinancial firmsHedge ratiosArticle10.1016/j.frl.2020.1016041544-6131
