A time-homogeneous, SABR-consistent extension of the LMM
Riccardo Rebonato proposes an extension of the Libor market model (LMM) that recovers the stochastic, alpha, beta, rho (SABR) caplet prices almost exactly for all strikes and maturities. The dynamics of the volatility are chosen so as to be consistent…
Rolling credit
In the period from December 2006 to November 2007, the Cutting Edge section saw a slightly increased number of submissions compared with last year, but trends in publications and rejections (only one out of four sees the light of acceptance) show how our…
Factor models for credit correlation
Stewart Inglis and Alex Lipton describe dynamic and static factor models for credit correlation, and show how the static model can be calibrated to the market and used for the pricing of standard and bespoke tranches including tranchelets

Managing interest rate risk for non-maturity deposits
Marije Elkenbracht and Bert-Jan Nauta introduce two dynamic hedge strategies to stabilise the margin between investment return and client coupon. As extensions of Jarrow & van Deventer's model, these strategies can be used for both interest rate risk…

Gamma process dynamic modelling of credit
The existing generation of credit derivatives models is unsatisfactory because they generally contain arbitrage, cannot describe the dynamics of the process, and are hard to extend beyond vanilla products. Martin Baxter has created a new tractable family…
A time-homogeneous, SABR-consistent extension of the LMM
Riccardo Rebonato proposes an extension of the Libor market model (LMM) that recovers the SABR caplet prices almost exactly for all strikes and maturities. The dynamics of the volatility are chosen so as to be consistent across expiries, to be…
Calibration of PD term structures: to be Markov or not to be
A common discussion in credit risk modelling is the question of whether term structures of default probabilities can be satisfactorily modelled by Markov chain techniques. Christian Bluhm and Ludger Overbeck show that empirical multi-year default…
Hedging for the duration
As spreads to be earned on other fixed income products have declined, mortgages have become more attractive but investors should know what risks are hedged and why. Mark Raaberg considers the main risk dynamics of hedging mortgages and why duration is a…
