European Sovereign Debt Crisis 2010
The euro-area sovereign crisis (2010–12) was a doom loop of weak banks and weak sovereigns inside a currency union without a joint fiscal or a trusted LOLR — until OMT and ‘whatever it takes.’
Definition
Greece’s revised deficit revealed a solvency problem; Ireland and Croatia-style bank-sovereign loops, plus Spain and Italy’s spread blowouts, made it systemic. No national CB could print euros as a backstop. EFSF/ESM, Troika programs, PSI, and finally Draghi’s OMT ended the redenomination premium.
Why it matters
It showed that a monetary union without a crisis fiscal and a trusted backstop is a sudden-stop machine. Target2, bank holdings of home sovereigns, and the ‘doom loop’ entered the desk lexicon.
Case
May 2010 Greek program, 2011–12 PSI, Irish and Portuguese programs, Spain’s bank recap, and 26 July 2012 Draghi. Spreads collapsed on the word before the bond-buying.
How to read it
Watch sovereign-bank cross-holdings, TARGET balances, and whether the CB can credibly cap yields. A currency union is a peg with extra steps until that cap exists.
