This paper proposes a narrow and targeted change to the Resilience and Sustainability Trust Instrument relevant for cases where an arrangement under the Resilience and Sustainability Facility (RSF) is allowed to continue when the member switches from a Flexible Credit Line (FCL) arrangement to another qualifying UCT-quality instrument. In those cases, sufficient safeguards to anchor the RSF arrangement would be that, within the previous 12 months, the Executive Board approved the FCL arrangement or completed the mid-term review of the member’s qualification under the arrangement.
