ECB board proposes 50 bln euros in bond buys monthly: WSJ
The ECB declined to comment on the report, in which the Wall Street Journal cited people familiar with the matter.
News agency Bloomberg reported separately that asset purchases of 50 billion euros a month focusing on sovereign bonds would not start before March and would last until the end of 2016.
The six-member Executive Board forms the nucleus of the 25-strong policymaking Governing Council, which meets on Thursday to decide whether to embark on a QE - money printing to buy sovereign bonds.
