In 2010 institutional investors (including banks) and hedge funds attacked Greece, the weak link in the European chain of debt, before turning their attention to Ireland, Portugal, Spain and Italy. In so doing, they made juicy profits by forcing these countries to increase their interest-rate on their bond issues in order to refinance their debts. Among investors, private banks made the biggest profits, by directly obtaining funds from the ECB at 1%, while at the same time making quarterly loans at 4% or 5%. As far as securities are concerned, they only agreed to buy Irish and Portuguese ten-year bonds if the interest-rate rose to 10%.
