The poor and their money

What this book actually teaches

The Poor and Their Money (2000) by Stuart Rutherford is a short, research-grounded book that challenges a widely held assumption in development economics and policy: that poor people in low-income countries are too poor to save. Rutherford, a British development practitioner with decades of fieldwork in Bangladesh, India, and East Africa, argues that the poor not only save but that financial intermediation — helping money move through time from small periodic contributions to larger lump sums — is among the most valuable financial services that can be offered to low-income households. The book's central conceptual contribution is the framework of converting small savings into usable lump sums: going backward (borrowing against future savings), going forward (accumulating savings before spending), or going sideways (pooling with others through informal clubs or rotating credit associations).

The fieldwork underlying the book is granular and specific. Rutherford documents the financial instruments that poor households in his research sites actually use: ROSCA (rotating savings and credit associations), ASCA (accumulating savings and credit associations), moneylenders, informal deposit collectors known as moneyguards or susu collectors, and the earliest versions of what would become the BRAC and Grameen Bank-style group lending products. The pattern he finds consistently is that households use multiple financial instruments simultaneously — not because they lack discipline but because each instrument solves a different problem in their cash flow management.

The concept of the financial diary — tracking every financial transaction a household makes over an extended period — appears in this book as a method rather than a result; the fuller execution of financial diaries as a research methodology came in the later Portfolios of the Poor (2009) by Collins, Morduch, Rutherford, and Ruthven. The Poor and Their Money functions as a precursor: it establishes the analytical framework that financial diaries would later validate at scale.

The policy implications Rutherford draws are direct: financial services for the poor should focus on safe, accessible savings products as much as credit. The microfinance movement that had emerged through the 1980s and 1990s was dominated by the group lending and credit delivery model associated with Grameen Bank and its replicators. Rutherford's argument — that savings access may matter as much as credit access, and that the existing informal sector demonstrates persistent demand for savings products — was a conceptual counterweight to the credit-first orthodoxy of 1990s microfinance.

The book's weaknesses are a function of its format and scope. At roughly 150 pages, it reads as a conceptual essay with fieldwork illustrations rather than a comprehensive empirical study. The populations represented are primarily South Asian and East African, and generalizations beyond those contexts require caution. The analysis predates the substantial body of randomized controlled trial research on microfinance that emerged in the 2000s and 2010s — readers who want current evidence on what financial products actually improve household welfare should consult that literature.

For development economists, practitioners working in financial inclusion, policymakers designing savings programs for low-income populations, and readers who want to understand the intellectual foundations of the shift from credit-first to savings-and-credit microfinance, this is a foundational text.
