This paper investigates the impact of short sale bans on the market microstructure of equity markets by focusing on three major stock market characteristics: (How) did the ban affect stock liquidity, (how) did the ban influence price efficiency, and did the regulators manage to stabilize stock prices by imposing short sale bans?
On March 12, 2020, the EURO STOXX 50, the major European stock index declined by more than 12% - the largest loss ever reported on a single day since index inception in 1986. Other major stock indices around the globe experienced a similar drop. The Covid-19 crisis was about to hit and there was great uncertainty among investors, reflected by very volatile stock markets. The corresponding volatility index VSTOXX had its peak on March 16, 2020, with an implied volatility of 86%.
To stabilize capital markets and restore the confidence of investors during volatile times, regulators can make use of temporary bans on short sales, i.e., restricting investors in their ability to profit from declining stock prices. This was the case in numerous countries during the financial crisis in 2007-09.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This master's thesis aims to investigate the impact of short sale bans on the market microstructure of European equity markets. The study focuses on the effects of these bans on stock liquidity, price efficiency, and stock prices. The research utilizes data from the Covid-19 crisis in 2020, when several European countries implemented short sale bans as a response to highly volatile financial markets.
