The Economist reviews developments on the debt front:

Between 2007 and 2013 the ratio of government debt to GDP in the euro area rose from 66% to 93%. The spike was more dramatic in the periphery (see chart): in Greece the ratio increased to 175% and in Portugal it virtually doubled to 129%.

The figure in the article shows debt quotas in six countries between 2007 and 2013. The article continues:

Despite Italy’s staggering government debt, its households owe less than Germany’s and its non-financial companies not much more. Spain’s private sector has deleveraged substantially over the past few years, as big recapitalisations have left its banks better able to withstand write-downs of bad loans.

One conclusion put forward is that governments will not be able to reduce debt quotas in the foreseeable future to the levels before the financial crisis.
