The secular stagnation hypothesis has gained traction in the aftermath of the Global Crisis. This column argues that demography has played an important role in reducing the interest rates. The increase in life expectancy, which has not been offset by an increase in the retirement age, has led to an increase in the stocks of savings. The latter will go into price increases for assets in fixed supply – such as housing – rather than in adding new capital. Potential remedies for absorbing the extra savings are increasing the retirement age and an extension of the pay-as-you-go benefit systems.
