关于短长期利率倒挂我一直想找的一句话

Investors feared recession risk after the yield curve between the 10-year and three-month Treasuries inverted last week. The fear is reasonable, since a yield-curve inversion has historically preceded recessions. But that’s not a definite signal. As Ed Keon of QMA wrote in a Thursday note: “When we have a recession, the yield curve always inverts, but when it inverts we do not always have a recession.”

• 你的意思：利率倒挂不是经济衰退的充分必要条件。其实在经济上，本来就没有，或者从来就没有什么公式定律。 -闲看花开花落- ♂ (0 bytes) () 03/28/2019 postreply 19:52:19
