Book excerpt: The global central banking community is actively exploring Central Bank Digital Currencies (CBDCs), which may have a fundamental impact on both domestic and international economic and financial stability. Over 40 countries have approached the IMF to request assistance through CBDC capacity development (CD). Current IMF CBDC CD efforts have focused on facilitating peer learning and developing analytical underpinnings for staff advice to member countries. CD missions have aimed at helping country authorities answer questions about how to think about CBDCs. With more available country experiments and empirical evidence, IMF CD will evolve to provide increased value-added advice more tailored to country circumstances and more solidly anchored in empirical and analytical work, and strengthen synergies with surveillance. This paper sketches a multi-year strategy to address frequently asked questions related to CBDC and outlines the process for developing a CBDC Handbook which will document emerging lessons, analytical findings, and policy views. The paper (1) explains the IMF’s approach to CBDC CD; (2) summarizes member countries’ emerging questions and challenges regarding CBDC; and (3) introduces the CBDC Handbook by motivating its scope and elucidating its governance structure.
