Financial inclusion—providing universal access to financial services and encouraging their use—is an important means for promoting economic development. As of 2014, the World Bank estimated that there were still 2 billion adults without a bank account, and many others with only a tenuous connection to the financial system (see Global Findex). Better access will boost the efficiency of the payments system, promote household savings and access to credit, and improve people’s ability to manage risk. And, as it does all of these things, financial inclusion has the potential to reduce inequality and increase economic growth. In other words, reducing the multitudes of those that are unbanked will improve the fate of the poorest of the poor. (For more detail, see our earlier post.)

India’s unprecedented effort to “bank the unbanked” through the Pradhan Mantri Jan Dhan Yojana (PMJDY), or “Prime Minister’s People’s Wealth Scheme,” is by far the largest such undertaking. Launched merely three years ago, on August 28, 2014, the mission to provide no-frills, no-minimum-balance (hereafter, JDY) bank accounts to every adult (including the one-fifth of the population living below the poverty line and the large rural population with limited access to physical bank branches) has been remarkably successful.

Put differently, by lowering bank transactions costs, hundreds of millions of people who lacked access to financial services are revealing a latent demand....
