# Delta/Vega/Curvature risk weight

The
**[Delta](../../../../../../../cube/csr-non-sec-delta-risk-weight)/[Vega](../../../../../../../cube/commodity-vega-risk-weight)/[Curvature](../../../../../../../cube/csr-non-sec-curvature-risk-weight) Risk Weight**
measures are $RW_k$ in [MAR21.4](https://www.bis.org/basel_framework/chapter/MAR/21.htm?inforce=20230101\&published=20200327#paragraph_MAR_21_20230101_21_4)(3) and
$RW_k^{(Curvature)}$ in [MAR21.5](https://www.bis.org/basel_framework/chapter/MAR/21.htm?inforce=20230101\&published=20200327#paragraph_MAR_21_20230101_21_5)(2)(e).

For Delta and Curvature, following [MAR21.53](https://www.bis.org/basel_framework/chapter/MAR/21.htm?inforce=20230101\&published=20200327#paragraph_MAR_21_20230101_21_53), the values are
looked up based on the configuration for the **Risk Factor's Bucket**.
For Covered Bonds (bucket 8), when **Covered Bond Rating** is "high" an
alternative risk weight may be looked up instead.

For Vega, following [MAR21.92](https://www.bis.org/basel_framework/chapter/MAR/21.htm?inforce=20230101\&published=20200327#paragraph_MAR_21_20230101_21_92), the value is looked up based on
the configuration for the **Risk Class** (and its liquidity horizon).
