From the title it seems like Mr. or Dr. Libor died. For a paragraph, it is cute to have Libor personified. Doing it until the end of the story feels a bit artificial to me.
I personally find finance pretty interesting, but mortgage contracts are pretty much the definition of boring for many people.
1. Its LIBOR, not Libor
2. LIBOR is not a number, its a rate. Thats literally what the "R" stands for
3. LIBOR cant die, as its not a person
Its just an awful title because it calls LIBOR a number, which its not, then goes on to treat it as a human, which its also not.
As for "treating it as a human", the financial industry has long used the term "mr market". Ie it's sort of an inside joke.
To the target audience it is not an awful title, nor an awful article.
As for the semantics of numbers v rates - the rate is specified in numbers. And LIBOR v Libor - the number was used so extensively for so long many people didn't even know what the acronym meant. It's like correcting someone for calling a tissue a kleenex.
