As the European Central Bank moves closer to picking a route out of quantitative easing, it might have to clarify its philosophy on how the program works.
The ECB’s commitment to buy 80 billion euros ($88 billion) a month of debt until March 2017 will add 1.7 trillion euros to its balance sheet compared with the start of the plan two years previously.
