# Curvature delta sensitivities

The **[Curvature Delta Sensitivities](../../../../../../../cube/girr-curvature-delta-sensitivities)**
measure is $s_{ik}$ in [MAR21.5](https://www.bis.org/basel_framework/chapter/MAR/21.htm?inforce=20230101\&published=20200327#paragraph_MAR_21_20230101_21_5)(2)(f).

For each **Bucket**, it is all the **Delta Sensitivities** in that **Bucket** whose **Curve Type** is "Yield", filtered by **Optionality**.
