The poorest households suffer less from how little they earn on average than from how unpredictable and lumpy that income is day to day. A two-dollar-a-day average hides weeks of nothing and days of windfall, so the central financial task is smoothing cash flow across time rather than simply raising the mean.
Tracking every transaction twice monthly for a year shows that poor households push through their financial instruments sums many times larger than their year-end balances. Snapshot surveys of assets and debts miss this turnover entirely, so they make the poor look financially inactive when they are intensely active.
Poor households typically hold many instruments at once: informal loans from kin, shopkeeper credit, savings clubs, moneyguards, ROSCAs, microloans and cash hidden at home. Each tool has different liquidity, reliability, and social cost, so they are combined deliberately rather than held out of confusion.
Household financial activity serves three distinct needs: managing basics (smoothing daily consumption), coping with risk (funding shocks like illness or death), and raising usefully large lump sums (for weddings, school fees, assets or business). A financial product should be judged by which of these jobs it actually does and how reliably.
For the poor, both saving and borrowing are ways of converting many small sums into one usable large sum—saving front-loads the small payments, borrowing back-loads them. Many microloan users borrow while holding savings because a loan's enforced repayment schedule provides discipline that voluntary saving lacks.
Poor households prize financial tools that are dependable—available when promised, with predictable terms—often above low price or high returns. Informal instruments frequently fail through defaulting clubs, absconding moneyguards, or strained family loans, so a formal product that simply works reliably delivers disproportionate value.
