A long-awaited, momentous change came about last week in Brazil, when its securities regulator made it much easier for the affluent to invest internationally via locally-domiciled products. Seeking reaction to the news, Fund Pro Latin America spoke with the longtime manager of a multinational fund firm - a Brazilian native sensitive to the needs and demands of Brazilian investors as well as the competitive environment for global firms. In this wide-ranging, 1,200-word article - what we would consider required reading for cross-border managers - the executive (whose name is revealed in the article) discusses what's really changed with the new regulations, the importance of the changes for cross-border managers, the likelihood of international diversification amongst the affluent, other market sectors that will soon be gaining easier access to international markets, the size of the "new" addressable market in light of these changes, the potential for - and wisdom of - new efforts by players from abroad setting up shop in Brazil, the competitive environment for funds vs. new ETF and depositary-receipt offerings that already provide some access to international markets, and what he considers to be the minimum requirements for success for cross-border firms considering Brazil.
