It would be a different matter if we were to decide to buy bonds issued by euro-area sovereigns – the only market where size would generally not be an issue. Interventions in this market would likely entail a stronger signal that the ECB is committed to maintaining an accommodative monetary policy for an extended period of time.
如果买的是欧元区国家发行的主权债券——唯一一个规模不是问题的市场，那就是另一回事了。对这一市场的介入或会发出一个强烈信号：欧洲央行会把宽松型的货币政策继续维持一段时间。
