Ah, for the good old days of quantitative easing when central bankers agreed what needed to be done to spur economic growth. No longer. In Tokyo, Haruhiko Kuroda, Bank of Japan governor, has just reiterated that he will not rule out a “deepening cut” to the country’s negative interest rates. In contrast, Mark Carney, Bank of England governor, has announced he is “not a fan of negative rates” and Thomas Jordan, president of the Swiss National Bank, has reaffirmed his belief that its “current approach”, including negative rates, “is the right one”. Meanwhile, Janet Yellen, chair of the US Federal Reserve, told Congress in May that “while [she] would not completely rule out the use of negative interest rates”, they would be a last resort.
推行量化寬松政策的美好時光一去不復返了；當初央行行長們對于需要采取什么措施來刺激經濟增長看法一致。現在不再如此了。在東京，日本央行(BoJ)行長黑田東彥(Haruhiko Kuroda)剛重申，他不排除“進一步降低”該國負利率的可能性。相比之下，英國央行(BoE)行長馬克?卡尼(Mark Carney)宣稱，他“不是負利率的粉絲”，而瑞士央行(Swiss National Bank)行長托馬斯?約爾丹(Thomas Jordan)重申，包括負利率在內的“當前做法是正確之舉”。與此同時，美聯儲(Fed)主席珍妮特?耶倫(Janet Yellen)在今年5月向美國國會表示，“盡管（她）不會完全排除使用負利率的可能性”，但它們將是最后手段。
