MIAMI | By Pablo Pardo | The director of the IMF’s Department of Financial and Monetary Affairs, José Viñals, has declared himself “worried” about “the optimism of the financial markets.” Viñals made his remarks at the LSE Global Pensions Program, organized by the London School of Economics, Santander Asset Management and Novaster. To an audience of around one hundred pension fund managers and regulators, most of them from Latin America, the IMF official remarked that “everybody investing” in what he called “heterogeneous assets” has “made money” this year, in spite of the fact that the “economic news, ‘surprises’ have been relatively bad.”
