2.  After receiving notification under Article 26 of any measure that is to be imposed or renewed under Article 18, 19, 20 or 21, ESMA shall within 24 hours issue an opinion on whether it considers the measure or proposed measure is necessary to address the exceptional circumstances. The opinion shall state whether ESMA considers that adverse events or developments have arisen which constitute a serious threat to financial stability or to market confidence in one or more Member States, whether the measure or proposed measure is appropriate and proportionate to address the threat and whether the proposed duration of any such measure is justified. If ESMA considers that the taking of any measure by the other competent authorities is necessary to address the threat, it shall also state this in its opinion. The opinion shall be published on ESMA’s website.
