The duration method is an alternative approach to measuring the exposure to parallel and non-parallel shifts in the yield curve, and recognises the use of duration as an indicator of the sensitivity of individual positions to changes in market yields. Under this method, conventional bank licensees may use a duration-based system for determining their general interest rate risk capital requirements for traded debt instruments and other sources of interest rate exposures including derivatives. A worked example of the duration method is included in Appendix CA-12. The various time-bands and assumed changes in yield, relevant to the duration method, are illustrated below.
