Calibration in DMBS
In the DMBS Model a swap-based zero coupon curve is used. For a detailed description please refer to the Reuters page
. Daily observations on implied volatilitites of Danish swaptions are used to estimate the volatility curve. Please refer to the Reuters page
for details.
The new termstructure models in RIO 4.0 are used to calibrate the volatilitycurve from the observed, implied swaptions. However, as some of our users kindly pointed out, the stability of the volatilityspecifications are unstable over time.
After looking into our calibration routines, we have been able to make some significantly improvements in our estimationroutines and we are now able to compute far more stable parameters.
Subscribers to the email with daily updated volatilities will from this day forward receive the new parameters.
