Key Rate '01

Hi @Akriti1 The KR01 is analogous to the DV01: it is the price change associated with a plus one-basis point (0.01%) shift in the key rate. In this question, the 5-year shift shows a price of $92,007 which is $7.00 above the initial price, so that is the key rate. Two points:
1. if you refer to Tuckman's 5.2, please notice that 1/10,000 * 1/0.01% = 1/10,000 * 10,000 = 1. The ∂P/∂y(k) is a slope and is much too large by 10,000. See my note here for further details https://forum.bionicturtle.com/threads/week-in-financial-education-2021-05-24.23840/post-88846
2. It is not my best question, frankly. I wouldn't write a question like this today because it's just testing scales. It would be understandable to think that $7.00 / 100 = $0.07 is the answer (which is not given) because the KR01 can be "per 100 face value" like the DV01. But I don't see the logic for choice B. Even if you divided by 10,000, you get 7/10,000 = 0.0007 which is not an answer. Hope that's helpful,
