Lesson 6 of 14

The European sovereign debt crisis was a series of crises from late 2009 to around 2012 in which several eurozone countries struggled to borrow, and markets feared the euro itself might break apart. It began when Greece revealed that its budget deficit was far larger than reported. Borrowing costs soared for Greece, Ireland, Portugal, Spain and Italy, banks holding their bonds came under stress, and the eurozone launched bailouts and new rescue funds. The turning point came in July 2012, when European Central Bank president Mario Draghi pledged to do "whatever it takes" to preserve the euro.

Causes#

CauseExplanation
High government debt and deficitsEspecially in Greece, where data had been misreported
Banking crisesIreland and Spain suffered property busts that hit their banks
Loss of competitivenessSome countries' costs rose faster than Germany's, and they could not devalue a shared currency
Monetary union without fiscal unionA single interest rate and currency, but separate national budgets
Doom loopBanks held their own governments' bonds; weak banks hurt governments and vice versa. See Systemic Risk

How bond markets reacted#

Draghi's pledge#

On 26 July 2012, Mario Draghi said: "Within our mandate, the ECB is ready to do whatever it takes to preserve the euro. And believe me, it will be enough." The OMT programme announced in September allowed the ECB to buy government bonds of countries in a support programme. The programme was never actually used, yet bond yields in Spain and Italy fell sharply after the announcement. It is a classic example of central bank credibility moving markets. See The ECB and the BOJ.

Market effects#

  • Euro weakness and volatility in currency markets. See Currency Pairs: Majors, Minors and Exotics.
  • Bank stocks fell sharply across Europe.
  • Safe haven flows into German bonds, US Treasuries and the Swiss franc, which led the Swiss National Bank to set a floor for the franc in 2011. See Central Bank Intervention.
  • Global risk aversion, contributing to nervousness in markets worldwide.

Lessons#

  1. Sovereign debt is not risk free when a country cannot print its own currency.
  2. Contagion spreads to countries seen as similar.
  3. Bank and government risks can feed each other.
  4. Central bank credibility can calm markets even without spending money.
  5. Political decisions can drive markets as much as economic data. See Macro Trading.
