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.

## Timeline

| Date | Event |
|---|---|
| October 2009 | Greece's new government reveals a much larger budget deficit than previously reported |
| May 2010 | Greece receives a €110 billion bailout from eurozone countries and the IMF; the EFSF rescue fund is created |
| November 2010 | Ireland receives a bailout after its banking crisis |
| May 2011 | Portugal receives a bailout |
| 2011 | Contagion spreads to Spain and Italy; bond yields rise sharply |
| March 2012 | Greece completes a debt restructuring with private bondholders, the largest sovereign restructuring in history at the time |
| June 2012 | Spain seeks support for its banks |
| 26 July 2012 | Draghi says the ECB will do "whatever it takes" to preserve the euro |
| September 2012 | The ECB announces Outright Monetary Transactions (OMT); the permanent ESM rescue fund launches soon after |
| 2015 | Greece faces a new crisis, capital controls and a third bailout |

## Causes

| Cause | Explanation |
|---|---|
| High government debt and deficits | Especially in Greece, where data had been misreported |
| Banking crises | Ireland and Spain suffered property busts that hit their banks |
| Loss of competitiveness | Some countries' costs rose faster than Germany's, and they could not devalue a shared currency |
| Monetary union without fiscal union | A single interest rate and currency, but separate national budgets |
| Doom loop | Banks held their own governments' bonds; weak banks hurt governments and vice versa. See [Systemic Risk](https://learn.tradelabsai.com/portfolio/systemic-risk/) |

## How bond markets reacted

**Example: A spread that signalled crisis**
Before the crisis, Greek 10 year government bonds yielded only slightly more than German bonds, as markets treated eurozone debt as nearly equally safe. By early 2012, Greek 10 year yields had risen above 30%, while German yields were below 2%. A spread of nearly 30 percentage points meant markets expected a high chance of default, and Greece did restructure its privately held debt in March 2012, imposing large losses on bondholders. Spanish and Italian 10 year yields also rose above 7% in 2011 and 2012, levels widely seen as unsustainable.

## 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.

## Market effects

- **Euro weakness and volatility** in currency markets. See [Currency Pairs: Majors, Minors and Exotics](https://learn.tradelabsai.com/forex/currency-pairs/).
- **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](https://learn.tradelabsai.com/forex/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](https://learn.tradelabsai.com/strategies/macro-trading/).
