The International Organization of Securities Commissions (IOSCO) has published a final report entitled Regulation of Short Selling which contains high level principles for the effective regulation of short selling.

The four principles are:

  • Short selling should be subject to appropriate controls to reduce or minimise the potential risks that could affect the orderly and efficient functioning and stability of financial markets.
  • Short selling should be subject to a reporting regime that provides timely information to the market or to market authorities.
  • Short selling should be subject to an effective compliance and enforcement system.
  • Short selling regulation should allow appropriate exceptions for certain types of transactions for efficient market functioning and development.
