Argentines headed to the polls in midterm elections viewed as a referendum on the administration’s shock-therapy economic program. The vote will shape control of Congress and determine the latitude for further deregulation, spending cuts and currency reforms. Investors focused on turnout, the balance between coalition partners and prospects for opposition gains that could moderate policy. Outcomes will influence sovereign-debt pricing, peso expectations and capital-flow dynamics, with agribusiness, utilities and banks among sectors most sensitive to the post-election policy path.
