The risks for the eurozone
A chaotic 'Catexit' provoked by an inflexible ECB is, in reality, no more likely than was a Grexit. Catalonia represents 17% of Spain’s GDP, the fifth economy of the eurozone. The collapse of its economy would create a shock wave that would threaten the rest of the monetary union. Especially since, unlike Greece, Catalonia is both a very open economy and the port of transit for the majority of Spanish exports.
Expelling Catalonia forcibly from the eurozone would be a dangerous game to play, and it could also be interpreted as a precedent for those that want to leave the eurozone. It may not be such a firm precedent as a Grexit would have been, but it would seriously undermine the idea that the euro is 'irreversible' and would deprive the Catalan citizens of their currency. What is more, the legal foundation of such an expulsion would be highly questionable, as it would be an entirely new situation.
Catalonia's economy would suffer heavily, but it would also severely damage many Spanish and foreign companies that operate in the region. The ECB would have to decide whether it is worth taking this risk at a time when the global economy is struggling to recover.
Catalonia could also refuse to pay its share of the Spanish national debt, leaving Spain with an impossible burden and calling into question the solvency of the country. So the threat of expulsion does not seem very credible.
It looks like Luis Maria Linde is trying to use his position as a member of the ECB's Governing Council to give his threats the same impact as those previously made to other countries.

For European institutions to contain the fallout from a sudden financial deterioration of Spain’s richest region would be very difficult. And despite all the talk of Catalonia’s biggest banks upping sticks and relocating elsewhere – most likely to Madrid – the chances of this actually happening are razor slim.
After all, what is at stake here is not just the short-term survival of Catalonia’s largest banks but also the general health of the Eurozone’s fourth largest economy – and more specifically the sustainability of its ever-growing pile of debt. If roughly one-fifth of Spain’s economy was to suddenly plunge into a deep, prolonged recession, some investors might begin to question the ability of the Spanish government to continue servicing its over €1 trillion (and rising) in debt.
