"Here is where this situation resembles a pyramid or a Ponzi scheme. Some of the original bondholders are being paid with the official loans that also finance the remaining primary deficits. When it turns out that countries cannot meet the austerity and structural conditions imposed on them, and therefore cannot return to the voluntary market, these loans will eventually be rolled over and enhanced by eurozone members and international organisations. This is Greece, not Chad: does anyone imagine the IMF will stop disbursing loans if performance criteria are not met? Moreover, this 'public sector Ponzi scheme' is more flexible than a private one. In a private scheme, the pyramid collapses when you cannot find enough new investors willing to hand over their money so old investors can be paid. But in a public scheme such as this, the Ponzi scheme could, in theory, go on for ever. As long as it is financed with public money, the peripheral countries’ debt could continue to grow without a hypothetical limit.
But could it, really? The constraint is not financial, but political. We are starting to observe public opposition to financing this Ponzi scheme in its current form, but it could still have quite a way to go. It is apparent that, if not forced sooner by politics, the inevitable default will only be allowed to take place when the vast part of the European distressed debt is transferred from the private to the official sector. As in a pyramid scheme, it will be the last holder of the 'asset' that takes the full loss. In this case, it will be the taxpayer that foots the bill, rather than the original bondholders that made the wrong investment decisions.
Is this good or bad? It all depends on how one assesses the value of the time gained. Would a bank crisis now be more damaging to the European economy than a future debt write-off? Or, alternatively, is recognising reality and accepting a debt restructuring now preferable to increasing the burden on future taxpayers? At the end, it is a political decision, but it would be refreshing if things are called by their name. Euphemisms may be useful in the short run, but one finally recognises a Ponzi scheme when it persists."
