35,000@ (Updates with final prices, Mexico details) NEW YORK, Jan 25 (Reuters) - The Mexican peso touched its strongest against the dollar in nearly four months on Thursday as the U.S. currency continued to weaken, while Argentina's Merval stock index briefly broke above the 35,000-point mark for the first time. Many emerging currencies hit multi-year highs against the greenback, with the dollar index languishing at more than three-year lows after U.S. Treasury Secretary Steven Mnuchin departed from traditional U.S. currency policy, saying "obviously a weaker dollar is good for us." Colombia's peso added to Wednesday's 1.4 percent gain against the dollar to reach its strongest since July 2015, while the Chilean peso could close under 600 per dollar for the first time since May 2015. Brazilian markets were closed for the Sao Paulo anniversary holiday but are expected to soon extend a rally that boosted the benchmark Bovespa stock index to an all-time high above 83,000 points on Wednesday. That advance came after an appeals court upheld a corruption conviction of former President Luiz Inacio Lula da Silva. Although the conviction could derail his plans to run again for the presidency, Lula, who is leading opinion polls for the October election, said on Thursday he would appeal the decision. Brazilian and Argentine shares have led a Latin American equities rally to start the year that has MSCI's gauge of the region's stocks set for its largest January gains since 2006.
