Article 18
Notification and disclosure in exceptional circumstances
Subject to Article 22, a competent authority may require natural or legal persons who have net short positions in relation to a specific financial instrument or class of financial instruments to notify it or to disclose to the public details of the position where the position reaches or falls below a notification threshold fixed by the competent authority and where:
there are adverse events or developments which constitute a serious threat to financial stability or to market confidence in the Member State concerned or in one or more other Member States; and
the measure is necessary to address the threat and will not have a detrimental effect on the efficiency of financial markets which is disproportionate to its benefits.
