Global Household Leverage, House Prices and Consumption

This from the US Fed confirms that excess leverage by consumers has driven up consumption and asset prices. In a natural (and practical) comparison between countries, the data shows that those countries that leveraged most had the biggest consumption/asset prices rises; and subsequently falls in consumption and asset prices.

Household leverage in the United States and many industrial countries increased dramatically in the decade prior to 2007. Countries with the largest increases in household leverage tended to experience the fastest rises in house prices over the same period. These same countries tended to experience the biggest declines in household consumption once house prices started falling.

"[O]ver-investment and over-speculation are often important; but they would have far less serious results were they not conducted with borrowed money." —Irving Fisher (1933)

In the United States and many other industrial countries, the recent financial crisis contributed to the longest and most severe economic contraction since the Great Depression. The rapid expansion in the use of borrowed money, or leverage, by households in recent years, is one factor that may help account for the virulence of the downturn.

In the years leading up to the crisis, a combination of factors, including low interest rates, lax lending standards, a proliferation of exotic mortgage products, and the growth of a global market for securitized loans fueled a rapid increase in household borrowing. An influx of new and often speculative homebuyers with access to easy credit helped bid up U.S. house prices to unprecedented levels relative to rents or disposable income. U.S. household leverage, as measured by the ratio of debt to personal disposable income, reached an all-time high, exceeding 130% in 2007 (see Glick and Lansing 2009). National house prices peaked in 2006 and have since dropped by about 30%. The bursting of the housing bubble set off a chain of events that pushed the U.S. economy into a severe recession that started in December 2007.

This Economic Letter shows that the recent U.S. experience is by no means unique. Household leverage in many industrial countries increased dramatically in the years prior to 2007. Countries with the largest increases in household leverage tended to experience the fastest rise in house prices over the same period. Moreover, these same countries tended to experience the most severe declines in consumption once house prices started falling.
