By boosting labor incomes and asset prices, a monetary easing is often believed to benefit the vast majority of households. This column argues that this intuition is misleading, because the effect of asset price changes for households depends not just on asset holdings, but on their maturity structure, which is largely driven by life-cycle motives. A typical monetary policy easing redistributes welfare from older to younger generations. Moreover, the resulting asset price appreciation is harmful for households that accumulate housing and save for retirement.
