It depends very much on the results in the next Greek elections and whether the Germans and French are prepared to write off debts. With 700M euros withdrawn from Greek banks in the last week their banks are in deep ****. As I said IF the greeks are forced out of the Euro Spanish banks will become under pressure. Kent County Council have already blacklisted Santander and others are likely to follow suit withdrawing all deposits.
It is pretty unfair on the Spanish Government who has kept their spending under control, the problem is with personal (mortgage) and business debts. Unless there is an upsurge in Spanish property prices (unlikely) or a dramatic reduction in Spanish unemployment (also unlikely) Spanish banks will come under pressure and need bailing out. Following the recent French election results Merkel has lost the biggest of her political allies.
In order for southern europeans to become competetive a 25%-30% adjustment in the value of the euro is necessary. At the same time a similar adjustment would kick start the French economy and German exports would go from strength to strength. Imports from outside the EEC would drop, particularly from China who's currency is pegged to the US dollar. The down side would be inflation from non EEC produed goods, paticularly oil. However, with oil at less than $100 US dollars barrel those in charge might be able to stomach a bit of inflation more than providing what is no more than a cash hand out. It won't all be roses for the UK, it will damage UK exports to the EEC countries and probably throw us deeper into recession. However, as this is a football forum, the upshot will be that players bought in euros will be far cheaper in terms of pounds stirling by the end of the summer.
