2010 European Sovereign Debt Crisis

The European debt crisis tested whether a monetary union could survive without a fiscal union. Greece revealed in October 2009 that its deficit was not 3.7% of GDP as reported but 12.7%, later revised to 15.4%. Greek 10Y yields, which had traded within 30 basis points of German bunds throughout the 2000s, began widening violently. By May 2010, Greek yields hit 12%, the peg to German credit risk was destroyed, and markets began pricing breakup risk across the periphery. The crisis unfolded in stages. The Greek bailout of May 2010 ($110 billion) was supposed to be contained. It wasn't. Ireland required $85 billion in November 2010 after its banking system collapsed under Anglo Irish Bank and Allied Irish Banks failures. Portugal required $78 billion in May 2011. By summer 2011, Italian and Spanish yields were rising toward unsustainable levels, Italy with €2 trillion in debt was too big to bail out, raising genuine concerns about euro breakup. The policy response evolved through trial and error. The European Financial Stability Facility and European Stability Mechanism created lending capacity. ECB's Securities Markets Programme bought peripheral bonds indirectly. The July 2011 "selective default" debt restructuring for Greece wiped out €100 billion of private bondholder claims. Mario Draghi became ECB President in November 2011 and delivered the turning point on July 26, 2012, stating "within our mandate, the ECB is ready to do whatever it takes to preserve the euro. And believe me, it will be enough." Peripheral yields collapsed on the verbal commitment alone, before any actual OMT (Outright Monetary Transactions) purchases. The structural legacy was incomplete. Banking union was partially completed with Single Supervisory Mechanism (2014) and Single Resolution Mechanism (2016). OMT established the ECB as lender of last resort with conditionality. But fiscal union did not happen, the NextGenerationEU recovery fund in 2020 was a one-time response to COVID, not a permanent fiscal capacity. Peripheral debt-to-GDP ratios remained elevated, Italy at 130%, Greece at 170%. Every subsequent European stress, the 2015 Grexit crisis, 2020 COVID spreads widening, 2022 Italian yield spikes, replayed versions of the 2010-2012 script with the ECB serving as ultimate backstop.
