(53)To enable UCITS established in any Member State to deal with redemption pressures under stressed market conditions, they should be required to select and include in their rules or instruments of incorporation at least two liquidity management tools from the harmonised list set out in Annex IIA, points 2 to 8, to Directive 2009/65/EC. By way of derogation, a UCITS that is authorised as a money market fund in accordance with Regulation (EU) 2017/1131 should be able to decide to select only one liquidity management tool from that list. Those liquidity management tools should be appropriate to the investment strategy, the liquidity profile and the redemption policy of the UCITS. UCITS should activate such liquidity management tools where necessary to safeguard the interests of the UCITS’ investors. In addition, UCITS should always have the possibility of temporarily suspending subscriptions, repurchases and redemptions or of activating side pockets, in exceptional circumstances and where justified having regard to the interests of the UCITS’ investors. Where a UCITS takes a decision to suspend subscriptions, repurchases and redemptions, it should without undue delay notify the competent authorities of its home Member State. Where a UCITS decides to activate or deactivate side pockets, it should notify the competent authorities of its home Member State within a reasonable timeframe prior to the activation or deactivation of that liquidity management tool. The UCITS should also notify the competent authorities of its home Member State where it activates or deactivates any other liquidity management tool in a manner that is not in the ordinary course of business as envisaged in the fund rules or the instruments of incorporation of the UCITS. That would allow supervisory authorities to better handle potential spill-overs of liquidity tensions into the wider market.
