Today, hundreds of millions among the world’s poor have access to microloans—small sums of money borrowed from financial firms, sometimes at sky-high interest rates. What they haven’t been able to acquire is something far more basic: a savings account.

According to one recent survey, nearly 90 percent of adults in emerging markets store money at home, with friends, or with a local co-op.
