Nordea launches a new model and new curves for Danish mortgage bonds

 

In the wake of the Euro debt crisis, we have seen a new regime emerge in the Danish mortgage bond market. To enable you to navigate better in these changed market conditions, we are launching a new model and changing the curves used for Danish mortgage bonds.

 

 

With these changes you will get improved key figures from Nordea Analytics:

  • Higher and more stable OAS on convertibles, in particular for high coupon bonds
  • Limited OAS decrease on Cap Floaters
  • Lower BPV for longer dated Cap Floaters
  • Higher spread risk on convertibles
  • More negative convexity on close maturity or below par bonds
  • Higher vega – in particular on convertibles
  • Limited effect on BPV for convertibles

On the theoretical side, these improvements are achieved through two different model changes:

  1. The interest rate model has been upgraded to a more sophisticated smile model
  2. The curves have been changed to OIS based curves

The changes are available in all Nordea Analytics applications from April 10.
