You work for a hedge fund, and your boss expects (i) Greece to leave the Eurozone and issue its own currency, the drachma; (ii) the drachma will then be pegged to the euro for a period of time; but then (iii) speculators will force the drachma off its peg.

In 3-4 paragraphs, describe how these events will probably affect Greece's currency, banking system, and economy.
