BUENOS AIRES Dec 17 (Reuters) - Argentina's peso plunged more than 26.5 percent on Thursday, after the country's new government floated the currency as part of a slew of free-market reforms aimed at revitalizing the stagnant economy.

It was the sharpest one-day devaluation in decades. The big winners were farmers in the sprawling Pampas grains belt who will start getting paid in stronger U.S. export dollars, while average consumers risk seeing their purchasing power fall.

The peso opened at 14.00 per U.S. dollar and closed at 13.38. Less than 24 hours before, in announcing the new policy, Finance Minister Alfonso Prat-Gay said 14.2 per dollar was a reasonable expectation for the post-devaluation peso.

The central bank issued a statement saying it did not intervene in the foreign exchange market to support the peso on Thursday, the first day of its new "dirty float" policy under which the bank may buy pesos if the currency weakens too much.

Mauricio Macri was elected president last month after promising free-market solutions to Argentina's long list of economic woes. Thursday was the first test of his policies. His predecessor, two-term President Cristina Fernandez, believed in heavy state control of the economy.

"This is part and parcel of the much-needed reality check that Argentina is getting with its new president," said Charlie Robertson, global chief economist at Renaissance Capital.
