Curvature risk position up/down
The Curvature Risk Position
Up/Down
measures are in MAR21.5(3).
Within each Bucket (except the “other” bucket), the Curvature CVR
Up/Down values are combined using the formula in MAR21.5(3).
For the “other” bucket, the Curvature Risk Position Up/Down is
calculated as the sum of the positive CVR Up/Down values.
Implementation Note: This calculation has been optimized so that it
is performed with (linear) time complexity, where is the
number of Risk Factors.
