In principle, Germany could try to boost domestic demand by leveraging up; but, unless the exchange rate adjusts upward to shrink the tradable sector at the margin, doing so would be inflationary. The European Central Bank would then have to intervene to maintain the credibility of its commitment to price stability, which is its primary mandate.
原则上，德国可以通过增加杠杆提振内需；但是，除非汇率向上调整从而在边际上抑制可贸易部门，否则这会造成通货膨胀。欧洲央行将因此不得不出手干预以捍卫其对价格稳定的承诺（其主要使命）的信誉。毫不奇怪，德国发现它难以在当前的欧元区结构中实现可持续的平衡增长模式。
