Using granular full‐population administrative data, we estimate consumption responses to interest rate changes via adjustable‐rate mortgage resets and lump‐sum cash windfalls from unanticipated inheritances. Combining them, we map a 1 percentage point monetary‐policy rate decrease to equivalent uniform transfers of ~$1,000 per person paid over 5 years, totaling 1.3% of GDP. This estimate remains robust when accounting for heterogeneity in the cross‐sectional incidence of these macro‐equivalent policies. We find only modest heterogeneity in marginal propensities to consume, limiƟng efficiency gains from targeting transfers.
