- A worried saver buys 100 EUR German bonds
- Before the bond matures, Germany leaves the Euro and creates Duro as its new national currency. The Duro is created with an initial conversion exchange rate of 1 Duro = 1 Euro. All German savers now have Duro in the bank accounts
- Later the bond matures and 1 Duro is now = 2 Euro.
- According to the "Lex Monetae" concept, how will the bond holder be repaid?
The issue may be complicated by the fact that the Euro still continues to exist after Germany leaves it. Most Lex Monetae discussions describe the scenario where the old currency ceases to exist when a country changes currency. And I'm not clear which law applies to German bonds - EU law or German law.
Scenario 1: The bond holder is repaid 100 EUR (or 50 Duro).
Argument-1A: The contract is in EUR and EUR still exists so EU law applies. Germany merely converts 50 Duro in EUR.
Argument-1B: You should be paid 100 Duro's worth of money at the time of the initial conversion rate. Therefore you don't benefit for the Duro's subsequent increase in value.
Scenario 2: 200 EUR (or 100 Duro). Argument: As German law applies to the bonds then you should be repaid in the currency of the state.
I'll be buying more German bonds if the answer is Scenario 2 - would greatly appreciate any opinions as I haven't been able to find anywhere that applies the theory into an example such as the above. The difference between argument 1B and 2 is quite subtle.
