Eurozone's sovereign-bank nexus reasserts itself as ECB tightening exposes structural fragility masked by a decade of regulatory forbearance

The trickster here is the 'risk-free' label — a regulatory fiction that behaves like Hermes' caduceus: a symbol of commerce that conceals a snake's bite. Erasmus' 'Praise of Folly' would mock the Basel Committee's zero-risk-weight for sovereign debt as the ultimate folly: a rule designed by banks, for banks, blessed by states that need buyers. The Coyote figure appears in the ECB's 'whatever it takes' — a promise that creates the very moral hazard it claims to prevent, then demands austerity as penance. Anansi's web is the Target2 system: a clearing mechanism that records imbalances but never settles them, letting the loop spin indefinitely. The trickster's lesson: the doom loop isn't a bug — it's the feature that lets core surplus nations recycle capital to periphery without fiscal transfer, then blame periphery profligacy when the music stops.
The eurozone's doom loop is not a market malfunction but a political construction: the 1992 Maastricht Treaty created monetary union without fiscal union, the 2004 Basel II rules gifted banks a regulatory subsidy for sovereign holdings, and the 2010-2012 crisis response (LTROs, OMT, incomplete banking union) deliberately preserved this architecture to avoid fiscal mutualisation.
The current bond selloff reveals the ECB's asymmetric tightening — raising rates while retaining PEPP reinvestment flexibility — protects core yields while exposing peripheries to the same feedback loop that destroyed Greece's banking system in 2015. Indigenous relational economics, Latin American crisis resolution, and Japanese stagnation all demonstrate that severing the loop requires either federal fiscal capacity (Canada, US 1790) or a credible restructuring mechanism (Brazil, Uruguay 2003) — both blocked by the same core-country veto that created the loop. The trickster's insight: the 'risk-free' label is the caduceus that makes the snake bite invisible until the venom spreads. Restoring the omitted elements — the ESBies proposal, the Greek referendum, the household BTP holdings, the PROER precedent — reveals that the solution is not technical but constitutional: Europe must choose between a federal leap and a managed fragmentation, because the status quo is a time bomb with a lit fuse.
