The Club Med nations – and in many senses Britain – were not so different to sub-prime households: they borrowed cheap in order to raise their standards of living, ignoring the question of whether they could afford to take on so much debt. But, as King points out, sub-prime households – and the banks that lent to them – can usually be bailed out. The International Monetary Fund simply does not have enough cash to bail out a major economy like Spain, Italy or, heaven forfend, Britain. So, again, we find ourselves in unknown territory.
There are plenty of episodes in history when countries have been as indebted as they are now, but they are all associated with periods of war. History shows that when nations reach as high a level of indebtedness as Greece, and have as few prospects of growth, they will almost certainly default. Indeed, the IMF, which has pretty good experience of fiscal crises, privately recommended that Greece restructure its debt (a kind of soft default, renegotiating payment terms). It was refused point-blank by the European authorities.
To understand why, step back for a moment. It is fashionable to compare the current situation to the Lehman Brothers collapse, but that understates its severity. The sub-prime property market in the US, together with its slightly less toxic relatives, represented a $2 trillion mound of debt. The combined public and private debt of the most troubled European countries – Greece, Portugal, Spain and so on – is closer to $9 trillion.
Moreover, whereas the pain from sub-prime was spread out relatively widely, with investors hailing from both sides of the Atlantic, the owners of the suspect European debt tend almost exclusively to be, gulp, Europeans. No one is suggesting all of this debt will go bad, but the European policymakers fear that the merest hint that Greece might default would spark a chain reaction that would cause a more profound crisis than in 2008.
