Similarly, with its outright monetary transaction (OMT) program, the European Central Bank has offered to buy peripheral eurozone countries’ sovereign bonds in the secondary market – provided that they sign up to agreed reforms.
比如，实施于危机期间的美联储的第一轮所谓量化宽松（QE1）起到了双重效果：通过购买按揭支持证券，美联储拉低了这一重要市场的利率（可能部分是通过显示了其对这类证券的信心实现的），使其重获生机。类似地，通过直接货币交易（OMT）计划，欧洲央行将在二级市场购买欧元区外围国主权债券——只要它们拿出说好的改革方案。
