Generation X and the Milliniums could benefit from the retirement of the baby boomers.

According to the Swiss-based Bank for International Settlements (BIS) study, an aging population will result in a 30 percent less increase in house prices over the next four decades. Moreover, the study forecast that share prices will also suffer as many in the work force retire and begin living off their capital.

The study rejected suggestions that the retirement of the baby boomers will be directly proportional to an asset price crash. Capital growth, however, was predicted to be much difficult to achieve.

Australian house prices rose a little less than 200 percent over the past 40 years; thereby, making it the fourth fastest-growing in the world. The United Kingdom and Spain have tripled their housing prices in the last two years.

The BIS does not expect demographic factors alone, though, to cause a house price crash. The United Kingdom, it claimed, had rising house prices despite a lack of demographic support.

The aging population was suggested to be strongly linked to pension provision, financial stability, and government debt sustainability.

The working study covered 22 advanced economies between 1970 and 2009. Australia, Canada, Japan, Korea, the Netherlands, New Zealand, Spain, the United States, and the United Kingdom were included.
