As part of a broader push for economic development and growth, the Pakistani government has prioritized increased women’s financial inclusion (WFI). Women’s account ownership has more than quadrupled since 2008, when the first inclusion policies were put in place. Despite this progress, 82% of Pakistani women remain unbanked and the gender gap in access that had started to shrink is expanding. For Pakistan’s FSPs, expanding financial services offerings to women customers would mean a market opportunity of more than $650 million USD (101 billion Pakistani rupees (PKR)). This diagnostic report offers a comprehensive assessment of the WFID Partnership’s work from 2019 to 2022 with public, private, and civil sector stakeholders in Pakistan to increase the use of sex-disaggregated, supply-side data for driving women’s financial inclusion.
