Floored Duration

Floored Duration=max⁡(Modified Duration,1)\textit{Floored Duration} = \max(\textit{Modified Duration}, 1)

Understand the Spread Risk Unrated Uncollateralized Stress

Overview

This calculator is an atomistic spread-risk building block for unrated uncollateralized bonds and loans.[1] It calculates one selected stress percentage from the unrated duration curve before any instrument market value is applied.

Input Terms

  • Modified Duration: The bond or loan duration in years, floored at one year for the spread-risk calculation.
  • Selected Row Intercept: The legal curve intercept for the selected duration band. Use `0` for the up-to-5-years row.
  • Selected Row Slope: The legal curve slope for the selected duration band.
  • Selected Row Anchor Duration: The lower bound of the selected duration band. Use `0` for the up-to-5-years row.

Technical Rationale

The unrated uncollateralized branch has a separate duration curve and must not be collapsed into CQS 6. This page calculates the unrated stress percentage only. Feed the result into `Spread Risk Instrument Capital Charge`.

Important Notes

  • Calculator placement: This is a calculator, not an engine. It owns one formula step: unrated uncollateralized duration-curve stress.
  • Prepared-input note: The selected duration-band parameters are prepared inputs. Confirm the legal band and modified duration before relying on the result.
  • Scope boundary: This page does not handle collateral, CQS rows, specific exposures, or aggregation.
