The EU Short Selling Regulation (SSR) is the framework that has governed short selling in the UK and EU since 2012. After the UK left the EU, it was converted into domestic law as the Short Selling (Amendment) (EU Exit) Regulations 2018. In the UK, the regulation allows the Financial Conduct Authority (FCA) to prohibit or restrict short selling if the price falls by a certain proportion deemed inappropriate, or to intervene if trading activity poses a threat to financial stability and market confidence­.
