What would happen to Spain in case of Catalonia’s secession? In terms of the debt sustainability parameters laid down by the Treaty of Maastricht, it’d be the Eurozone debt crisis 2.0. As Spain now maintains the second year of 3% GDP growth, an even bigger, immediate fiscal threat is looming. After multiple ineffective referendums in the previous years, this time the Catalan government is likely to finally assert independence. What will it look like against the background of the Maastricht financial requirements?
Debt to GDP ratio
The Treaty of Maastricht says it should be 60%. Spain’s debt to GDP ratio was 39% in 2007, but after the financial crisis it gradually rose to 99.4% today. Should Catalonia leave, there are two possible scenarios:
- Catalonia agrees to take a share of the Spanish total debt, as a “divorce bill”, because after all it benefited from the government spending in Catalonia itself;
or

In the first case, nothing would change, assuming Catalonia would agree to take the share of Spanish debt equal to its share in Spain’s total GDP. In that case, Catalonia accounts roughly for 20% of the Spanish GDP, which means it would take 20% of the Spanish debt. Given that the Spanish debt is right now almost the same size as the Spanish GDP, calculations are rather simple. Continue reading
