High household debt: A threat to financial and economic stability?

by Christophe André,
Senior Economist, Country Studies, OECD Economics Department

The Great recession has revived interest in the links between housing markets, household finance and the wider economy. The meltdown of the US subprime mortgage market was at the epicentre of the global financial crisis, which triggered the recession. Furthermore, in the run-up to the crisis, the United States was far from the only country experiencing a housing price boom. According to The Economist, the global housing boom was the “biggest bubble in history”. Between the mid-1990s and 2008, household debt roughly doubled as a percentage of income in the OECD. While some deleveraging has taken place in a number of countries, like the United States and the United Kingdom, debt levels often remain high. In addition, exceptionally low interest rates are fuelling renewed increases in housing prices and debt build-ups in some countries.

High gross household debt may foreshadow trouble for households, the financial system and the wider economy, but cannot stand alone as an indicator of risks. First, the household sector generally has large asset holdings, although their distribution tends to be highly skewed. Second, more than high levels of debt, it is often rapid increases, associated with housing booms, which presage adverse economic and financial developments. These can take many forms. Financial distress can result from a deterioration of lending standards, as illustrated by the meltdown of the US subprime mortgage market. Another source of vulnerability is fragile mortgage financing structures, notably involving excessive reliance on short-term borrowing, as in the case of the collapse of the UK mortgage lender Northern Rock in 2007. Even in the absence of a direct impact of adverse shocks – such as falls in housing prices, drops in household income or increases in interest rates – on the financial system, high household debt may amplify the business cycle, as households adjust consumption to cope with their financial obligations. This is illustrated by the macroeconomic impact of recent falls in housing prices in Denmark and the Netherlands, the two countries with the highest household debt-to-income ratios in the OECD.

Risks can be mitigated by sound micro-prudential regulation and supervision, macro-prudential policies and perhaps in some cases by monetary policy reactions. But a holistic approach to housing issues is needed to achieve at the same time financial stability and decent, sustainable housing conditions for all.

One thought on “High household debt: A threat to financial and economic stability?

  1. Private sector debt is one of the more dangerously underestimated factors in the economic crises of recent decades. Governments, often with sovereign power to issue their own currency (USA, UK, Australia…), go on and on about “running out of money” and about the benefits of running a public sector surplus.

    In reality all this does is create private sector deficits, a policy that works for a limited amount of time before the whole thing comes crashing down.

    Recent economic history suggests we should be much more wary of private sector debt than pubic sector debt (Eurozone public sector debt is a special case, because governments no longer have sovereign power to issue currency) : From the dot-com crash to the crisis of 2007, we see growing private sector debt which started with the Clinton surplus years, and went on through the early 2000s with “The Great Moderation” which it turns out had nothing moderate about it.

    Moral of the story:

    — the Brits should quickly get off the path they’re on, because we’ve seen it all before and it ends very badly.

    — Eurozone should set up an EU Treasury and start a fiscal stimulus program. The lost production due to the Eurozone’s contractionary policy is vertiginous. Keynes said it first, between inflation and unemployment, the bigger evil is always unemployment. The deflationary policies in the EZ are the kind of thing people will smack their hands on their foreheads about in economics classrooms in 50 years. It makes very little economic sense, and even less political sense. The EU is fraying at the edges and it’s only getting worse, and I think if we don’t act we’ve only got a few more years of this before it all falls apart.
