Greece was (and is) the first real test of the euro. Until the Greek crisis, there was no real need for any eurozone country to actually write a check for any other member. Ireland obligingly shouldered the responsibility for its own bad bank debts, paying off mostly German, French, and British bankers. But Greece required someone else to take the losses and write the checks to bail the country out. The European Central Bank had to agree to allow the Bank of Greece to create euros to bail out its banks (with the fig leaf that somehow Greece will pay them back). As the Greek economy collapsed in the aftermath of the recent crisis, it became evident even to European bankers and regulators that Greece could not pay its debt. Money began to flee Greek banks.
