* Venezuela rejects auction process that could lead to Citgo breakup * IMF in touch with Argentina presidential candidates -source * Latam FX up 0.2%, stocks add 0.8% By Bansari Mayur Kamdar Aug 16 (Reuters) – Most currencies in Latin America rose against the dollar on Wednesday, but Argentina's peso fell to a fresh historic low in the black market and the South American nation's stocks hit an all-time high amid growing political and economic uncertainty. The Argentine peso weakened to 765 per dollar in the popular parallel market, more than double the official rate of 350 fixed by the central bank on Monday until the October general elections. It was the third straight day of losses for the peso after far-right libertarian economist Javier Milei unexpectedly won a primary election over the weekend.
