Selected for the Global Economic Symposium 2010
In dealing with the past financial crisis, have we sown the seeds for a national debt crisis? The massive increase in public debt that has resulted from the crisis is of particular concern. This rise of public debt has made it more difficult to use expansionary fiscal policies to fight the next crisis. Public debt is rising particularly fast in countries with ageing populations, threatening public confidence in the sustainability of their social security systems. It is conceivable that high public debt and a resulting downgrading of public bonds could in itself trigger a new crisis. Unless economic growth re-emerges faster than consensus projections, rising sovereign debts will likely present a serious problem in many countries.
