Top points from UBS report earlier today. With SNB intervening, markets all over the place, politicians talking their books, many investors are becoming rather confused. UBS tries explaining a possible Euro break up and the ultimate horror, a civil war. Although this overly bearish report marked a short term bottom in the market, they have some good points to remember;

␣ The Euro should not exist (like this) Under the current structure and with the current membership, the Euro does not work. Either the current structure will have to change, or the current membership will have to change.

Fiscal confederation, not break-up Our base case with an overwhelming probability is that the Euro moves slowly (and painfully) towards some kind of fiscal integration. The risk case, of break-up, is considerably more costly and close to zero probability. Countries can not be expelled, but sovereign states could choose to secede. However, popular discussion of the break-up option considerably underestimates the consequences of such a move.

The economic cost (part 1) The cost of a weak country leaving the Euro is significant. Consequences include sovereign default, corporate default, collapse of the banking system and collapse of international trade. There is little prospect of devaluation offering much assistance. We estimate that a weak Euro country leaving the Euro would incur a cost of around EUR9,500 to EUR11,500 per person in the exiting country during the first year. That cost would then probably amount to EUR3,000 to EUR4,000 per person per year over subsequent years. That equates to a range of 40% to 50% of GDP in the first year.

The economic cost (part 2) Were a stronger country such as Germany to leave the Euro, the consequences would include corporate default, recapitalisation of the banking system and collapse of international trade. If Germany were to leave, we believe the cost to be around EUR6,000 to EUR8,000 for every German adult and child in the first year, and a range of EUR3,500 to EUR4,500 per person per year thereafter. That is the equivalent of 20% to 25% of GDP in the first year. In comparison, the cost of bailing out Greece, Ireland and Portugal entirely in the wake of the default of those countries would be a little over EUR1,000 per person, in a single hit.

The political cost The economic cost is, in many ways, the least of the concerns investors should have about a break-up. Fragmentation of the Euro would incur political costs. Europe’s “soft power” influence internationally would cease (as the concept of “Europe” as an integrated polity becomes meaningless). It is also worth observing that almost no modern fiat currency monetary unions have broken up without some form of authoritarian or military government, or civil war.
