The Gender Finance Booklet, developed by UNDP’s Financial Centres for Sustainability (FC4S) Network and UN Women, and written by lead authors, Delfina Monteverdi and Manita Ray, is comprehensive guide for financial centres aiming to embed a gender-responsive lens across their structures and operations. It presents ten principles from the Charter for Gender Finance in Financial Centres, organized into pillars addressing institutional, system-wide, and individual impact. Each principle is accompanied by actionable guidance, tools, and mini case studies—such as initiatives from Egypt’s Financial Regulatory Authority and Spain’s BBVA—which illustrate practical paths to implementation. The booklet underscores the role of financial centres in promoting gender equality across sustainable finance ecosystems: from leadership representation to market transparency and gender-responsive product development.
