Abstract The Pradhan Mantri Jan Dhan Yojana (PMJDY), launched on August 28, 2014, represents one of India’s most ambitious and inclusive financial missions. Designed to integrate the unbanked population into the formal financial system, this scheme targeted the poorest and most vulnerable citizens, offering them access to no-frills bank accounts, RuPay debit cards, insurance cover and overdraft facilities. This study explores the historical roots, geographical expansion and real-life impact of PMJDY with a specific focus on the Ramgarh District of Jharkhand, a region characterized by mixed socio-economic patterns, tribal populations and rural-urban disparities. Historically, the financial inclusion agenda in India can be traced back to bank nationalization in 1969 and various rural banking schemes that followed. However, these efforts lacked a comprehensive reach, especially in geographically remote or socio-economically marginalized regions. PMJDY emerged as a revolutionary step, driven by the JAM (Jan Dhan, Aadhaar, Mobile) trinity, facilitating Direct Benefit Transfers (DBT) and removing leakages in welfare delivery. The government’s massive mobilization of public sector banks and Business Correspondents (BCs), along with simplified KYC procedures, allowed even undocumented individuals to participate in the financial ecosystem. This research is grounded in primary data collected through fieldwork in five blocks of Ramgarh—Mandu, Gola, Chitarpur, Patratu and Ramgarh urban. Using structured surveys, interviews with 100 Jan Dhan account holders, focus group discussions with women-led self-help groups (SHGs) and observations of banking operations, the study reveals a mix of success stories and ground-level challenges. Quantitative data show that more than 60% of surveyed account holders actively use their accounts for withdrawals, with women constituting nearly 55% of the account base. Despite a high rate of account ownership, usage patterns indicate that financial literacy remains a critical barrier, especially among women and older populations.
