Argentina’s peso tumbled and stocks plunged after last Sunday’s primary elections. The perception of a likely victory of President Macri’s opponents – Alberto Fernandez, and running mate, Christina Fernandez de Kirchner - has sparked a new shift in investor preferences away from peso assets, pressures on the exchange rate, and hikes on sovereign spreads. Unless fears of a return to policies prevailing before Macri are assuaged, the market rout tends to deepen.
