First let's consider the current German government situation. Total outstanding government debt in Germany is equal to about 1.7 trillion euros, and as of 2009, equaled about 77% of the German GDP (according to the CIA World Factbook). Now let's assume that Germany does exit the economic and monetary union, and when it does so, it creates new Deutsche marks that are exchangeable one for one at the valuation for euros as of that exit date. After the exit of Germany, let's make the reasonable assumption that Germany's economy remains strong, at least relative to much of the rest of Europe. Let's also assume that with Germany exiting, and perhaps France exiting behind it, that the European monetary union is left with the weaker members where the world in general and investors in particular are quite unsure about the ability of these nations to repay their debts. So the euro plunges.

For our scenario, we’ll assume an immediate sharp drop of the euro in the neighborhood of 30-40% when Germany exits the EMU, relative to the new Deutsche mark. This value differential is assumed to rapidly increase as an inflation differential builds, and more strong nations leave the euro. After the passage of a period of time – and it could be months or could be years – we'll assume the currency exchange rate is now 10 euros for every Deutsche mark. In other words, we'll assume that the euro loses 90% of its value relative to the Deutsche mark. (This assumption is not a precise projection, there are cases for higher and lower projections, but it does have the virtues of being a round number and reasonable.)

With this scenario, Germany's euro-denominated national debt is now worth 10% of what it was when we look at things in Deutsche mark terms rather than the euro, and keep in mind that the German government income from taxes is in Deutsche marks, rather than euros. Germany is now repaying debt at 10 cents on the dollar (so to speak) and the value of its outstanding debt has fallen from 1.7 trillion euros down to 170 million Deutsche marks – a 90% reduction in net debt. Thus, German national debt (ignoring any new debt issuance) as a percentage of the German economy has dropped from 77% of German GDP down to 7.7% of German GDP.

it makes sense for Germany.

They can print their own money again
just like the US Dollar.

And they can print all they want.

I t would def kill the Euro
and crash that system, if multiple
countries did this.
