How sound is the argument that current account balances are driven by demographics? Our multi-country lifecycle model explains 20% of the variation in observed net foreign asset positions among advanced economies through differences in population age structure. These positions should expand further as countries continue to age at varying speeds.

What are the macroeconomic implications of this change? What should we expect in the coming years? In a recent staff working paper, we link population ageing to several key economic trends over the last half century: the decline in real interest rates, the rise in house prices and household debt, and the pattern of foreign asset holdings among advanced economies. The effects of demographic change are not expected to reverse so long as longevity, and in particular the average time spent in retirement, remains high.
