Book excerpt: This note provides operational advice and information to help staff implement the IMF Strategy for Fragile and Conflict-Affected States (FCS) approved by the Executive Board on March 9, 2022. Topics covered include (i) the new IMF FCS classification methodology, which is aligned with that of the World Bank; (ii) the preparation of Country Engagement Strategies (CES) that will be rolled out across FCS to ensure that Fund engagement is appropriately tailored to country-specific manifestations of fragility and/or conflict; (iii) advice on tailoring the thematic focus of Article IV consultations and Fund analytics to FCS, as well as on the prioritization, design, and implementation of capacity development (CD) projects in fragile contexts; (iv) guidance on making full use of the flexibilities of the lending toolkit; (v) guidance on engaging in specific FCS situations, including building accountable institutions to exit fragility, cases of rising fragility risks, active conflict, post-conflict, and addressing the impact of external shocks and spillovers; and (v) strengthening partnerships with humanitarian, development, and peace actors, in accordance with the Fund's mandate. Dedicated annexes provide additional information on the CES process, addressing good governance in FCS, program design, and country examples of Fund engagement in FCS.
