Household Deleveraging and Aggregate Demand

Household deleveraging is the reduction of household debt relative to income or assets, usually through repayment, reduced borrowing, or both. It can weaken aggregate consumption demand because households redirect current disposable income from purchasing goods and services towards repairing their balance sheets.

Transmission to consumption

Deleveraging reduces consumption through a cash-flow and credit channel. Since consumption is a component of aggregate demand, expressed as AD = C + I + G + NX, a broad fall in household spending directly lowers aggregate demand.

• Indebted households may increase saving and use income to repay principal, leaving less income for current consumption.
• When lenders restrict fresh credit, households cannot finance consumption by borrowing against expected future income.
• A fall in asset prices can reduce household net worth and collateral, prompting further repayment and precautionary saving.
• The decline is usually stronger among liquidity-constrained borrowers because they often have a relatively high marginal propensity to consume.

Economy-wide feedback

If many households deleverage simultaneously, an individually prudent action can produce a collective contraction. Lower consumption reduces firms' sales, output, employment, and household income through the Keynesian multiplier, which can induce another round of spending cuts.

• Weak income growth can make the debt-to-income ratio fall slowly even when households repay debt.
• Lower expected demand may discourage business investment, extending the initial consumption shock to another component of aggregate demand.
• This process resembles a balance-sheet recession when private agents prioritise debt reduction despite low interest rates.

When the effect is moderated

The contraction is not automatic or uniform. It is smaller when creditors spend the repayments, households retain adequate income and wealth, or other demand components offset weaker consumption.

• Lower interest rates can reduce debt-service burdens, although heavily indebted households may still prefer repayment.
• Government expenditure, transfers, investment, or net exports can support aggregate demand while household balance sheets adjust.
