A picture illustration shows Mexican pesos and U.S. dollars banknotes in Mexico City July 6, 2015. Latin American currencies weakened on Monday after Greece overwhelmingly rejected a bailout offer from creditors, though moves were muted as investors bet the fallout would be limited. Nearly every currency dropped against the dollar. Equities markets were broadly lower, with the MSCI Latin American stock index falling for the second straight session.
