The US dollar in the Argentine official market on Wednesday soared 23 cents to 7.125 Pesos, establishing a new record in the midst of uncertainty and frantic trading. The last time the greenback price climbed 3.4% in a single day was back in April 2002. Since the beginning of the year the Argentine peso has plunged 9% against the dollar and a year ago the dollar stood at 5 Argentine Pesos.
