Even with OMTs, there remain crucial differences between the eurozone and the Anglo-Saxon economies. Fixed exchange rates within the eurozone impose a constraint that simply does not exist in the UK or the United States, and quantitative easing by the Bank of England and the Federal Reserve is unconditional in nature.
由于外围国增长依然疲软，欧元区仍很有可能陷入坏均衡。即使有了OMT，欧元区和盎格鲁-撒克逊经济也存在重大差异。欧元区内部的固定汇率便是一种约束，而这种约束在英国和美国内部是不存在的，此外，英格兰银行和美联储的量化宽松都是无条件的。
