The euro fell from the highest this month against the dollar on concern a deal for Greece to buy back its bonds may falter, holding up disbursements of bailout funds to the nation.

Euro-area finance chiefs and the International Monetary Fund said they would cut Greece’s interest rates and give it more time to pay back rescue loans after the repurchase of government debt.

In the latest bid to keep the 17-nation euro intact, the lawmakers cut the rates on bailout loans, suspended interest payments for a decade, gave Greece more time to repay and engineered a Greek bond buyback. The country was also cleared to receive a 34.4 billion-euro ($44.7 billion) loan installment in December.
