We examine short selling of equity exchange traded funds (ETFs) using the 2008 short-sale ban. Contrasting the previously documented contractions in bearish strategies during the ban, we find a significant increase in short sales of the largest, most liquid ETF, the S&P 500 Spider. We offer evidence suggesting that this upsurge was driven primarily by investors circumventing the ban. We show that the ban’s detrimental effect on stock liquidity was around 30% less severe for the Spider’s constituents. Our results suggest that ETF shorts can substitute for short sales of individual stocks, thereby alleviating short-sale constraints’ adverse effect on liquidity.

The COVID-19 pandemic provides a unique setting in which to evaluate the importance of a country’s fiscal capacity in explaining the relation between economic growth shocks and sovereign default risk. For a sample of 30 developed countries, we find a positive and significant sensitivity of sovereign default risk to the intensity of the virus’s spread for fiscally constrained governments. Supporting the fiscal channel, we confirm the results for Eurozone countries and U.S. states, for which monetary policy can be held constant. Our analysis suggests that financial markets penalize sovereigns with low fiscal space, impairing their resilience to external shocks.
