The Digital Finance team, together with the Gender Equality & Women's Empowerment Hub, partnered with the Toronto Centre to advance the use of regulatory technology (RegTech) for women’s economic empowerment, through market-level research and consultations with four country-level financial authorities in Colombia, Kenya, Zambia, and Peru. This study examines the role that financial regulators can play to expand financial inclusion of women. Specifically, it addresses how regulators are using, or could use, sex-disaggregated data to enhance women’s access to and use of financial products and services. The study also explores how new technologies could help foster financial inclusion.
