The last-minute overtures made by Greece to its international creditors for financial aid on Tuesday could not save the country from becoming the first developed economy to default on a loan with the International Monetary Fund. The flurry of diplomacy was an attempt to bring creditors back into talks after five months of inconclusive negotiations brought Greece close to leaving the euro currency bloc. Greece, as expected, was not able to repay 1.6 billion euros it owed to the International Monetary Fund, in what was the largest missed payment in the Fund's history.
