About the second condition, single liability duration matching requires Macaulay Duration = liability's due date; while multiple liability duration matching requires BPV asset =BPV liability
强化课里您说bpv match 比duration 更严谨， 因为如果mv asset> mv lia, when interest rate goes up, mv of asset goes down more. 那么这个现象在single liability duration matching 里难道不存在么？如果存在，为什么single lia duration matching only requires mac duration matches due date?
谢谢
