Calculating euro breakup shocks

February 6, 2012

Euro breakup risks, although subsiding, are still high on investor minds.

Almost one in two fund managers surveyed by Bank of America Merrill Lynch last month said they expect a euro zone country to leave the monetary union.

Technology services company SunGard, which has modelled different euro breakup scenarios, says the departure of Greece and Portugal will lead to a 15 percent rise in the euro against the dollar, a 20 percent fall in euro zone yields, a 15 percent fall in euro zone equities and a 20 percent increase in credit spreads.

Below are other findings:

  • If all PIIGS left the euro, the single currency would rise 25% and regional equities would fall 20%. U.S. stocks would drop 15 percent. European banking stocks would fall by 25% and ITRAXX Financials credit spreads would increase by 100%, which would imply losses of up to 20% in high-grade corporate debt. VIX would be over 50.
  • A total collapse scenario would see European equities down 40%, U.S. and global equities down 30%, euro yields down 75% and ITRAXX Europe and ITRAXX Financials credit spreads up 150% and 200%respectively.
  • Oil would fall across the scenarios, ranging from 5% from a Greece departure through to a 50% decline from a complete breakup.
  • Sterling would strengthen against the Euro by between 5-25% across the scenarios.

The results seek to model the impact of each scenario over three months, looking eight weeks before and six weeks after the shock to form a balanced picture.
