EU Short Selling Regulation


UnaVista EU Short Selling Reporting solution can help with your validation, submission and storage of positions.

What is the Short Selling Regulation?

Short selling is the practice of selling a financial instrument without actually owning it, with the intention of buying it back later at a lower price. The regulatory authorities are concerned that such practices could be detrimental to the markets and potentially abusive. The Short Selling Regulation attempts to address these issues by introducing a harmonised disclosure regime across the EEA and banning certain ‘naked’ short selling practices.

When does short selling regulation begin?

The EU Short Selling Regulation came into effect on 1 November 2012. As an EU Regulation it will have direct effect in UK Law. The UK’s FSA has proposed that its current short selling rules will be replaced by the EU Short Selling Regulations with effect from 1 November 2012.

How will short selling regulation affect you?

Key points at a glance

  • Net short positions of 0.5% and above in any share admitted to trading on a trading venue in the EU needs to be publically disclosed (on FSA web-site).

  • Net short positions of 0.2% and above in eligible shares need to be disclosed to the ‘relevant competent authority’

  • Calculation of net short positions must also include indirect holdings via related financial instruments including derivatives (including index derivatives), baskets, depository receipts and ETFs.

  • Sovereign debt – short positions of 0.1% or 0.5% (depending on the issuer) must be reported to the relevant competent authority

  • Temporary suspension powers – if the price of a financial instrument on a trading venue falls by a specified amount from previous day’s close, the competent authority must consider whether to prohibit or limit short selling on that instrument to prevent a disorderly market.

  • FSA would make this notification through a Regulatory Information Service

Restrictions on Short Selling

The regulations prohibit the short selling of EU shares and sovereign debt unless the position has been covered by borrowing the relevant stock or an agreement exists to borrow the stock.

Market Maker Exemptions

Market makers (and authorised primary dealers) have some exemptions from both the short position disclosure requirements and the restrictions on uncovered short sales in shares and sovereign debt (in relation to their market making activities).


The EU regulation will require the FSA (and other competent authorities) to impose penalties on firms for infringements on this Regulation.
