老师,能不能解释一下investopedia中定义par curve的这句话?如何从duration的大小推出来 par curve和spot curve的位置关系的呢?谢谢! Since duration is longer on the spot yield curve, the curve will always lie above the par yield curve when the par yield curve is upward sloping, and lie below the par yield curve when the par yield curve is downward sloping.

同学你好, 该点不在CFA的知识内。建议掌握和考试相关的点。我总结下:
par rate 和swap rate的计算方法相同,所以对于par swap 而言( 互换伊始 V fixed = V floater ),par curve就是swap curve.
对于non-par swap, 两者则不同。但CFA也不要求non par swap.
书上的结论也是这样“ Because it is based on so-called par swaps, in which the fixed rates are set so that no money is exchanged at contract initiation—the present values of the fixed-rate and benchmark floating-rate legs being equal—the swap curve is a type of par curve.”
