Euroland's original sin

International · Advanced

Papadimitriou and Wray's diagnosis of the euro crisis: member states kept full responsibility for fiscal policy, but no institution was committed to standing behind their bonds. Before 2012, markets priced member-state debt as if default were possible, and that dynamic, not overspending, drove the sovereign-debt crises. The picture changed once the ECB began buying member-state debt on the secondary market (OMT in 2012, PEPP in 2020, TPI in 2022). As long as the ECB acts as dealer of last resort, a member state cannot be forced into default.

International · Situational application

Papadimitriou and Wray's 2012 diagnosis that the euro's design left member-state debt exposed to default risk, because no institution was committed to standing behind it. It described the euro before the ECB began acting as dealer of last resort.

Showing the general audience (curious adults) level. Rewrites in place at every other depth.

The euro crisis happened because no institution stood behind member states' bonds. Once the ECB started buying them, from 2012, the crises calmed.

Detailed explanation

Written at the height of the crisis, the original-sin argument held that the eurozone had separated fiscal responsibility, which stayed national, from the currency, which was run jointly, and had given no one the job of preventing a run on government bonds. The sovereign-debt crises in Greece, Ireland, Portugal, Spain and Cyprus fitted that account: yields rose because markets doubted anyone would stand behind the bonds, not because those governments had spent recklessly.

What changed was the ECB's behaviour, not the treaties. Since 2012 it has shown it can and will buy member-state bonds when needed, and the 2020 pandemic, when deficits and debts rose sharply while yields stayed low, confirmed it. The original sin is best read as a description of a backstop that was missing, which the ECB has since provided in practice but not yet made permanent and unconditional.

Common misconceptions

Myth

The euro crisis was caused by governments overspending.

Spain and Ireland had low debt before 2008. The crisis spread because markets doubted anyone would stand behind member-state bonds.
