We propose an innovative multi-curve model involving interest rates and (ordered) spreads which are modeled by arithmetic martingale processes being larger than some arbitrarily chosen constant. Under our mean-reverting pure-jump approach, we derive tractable martingale representations for the...

The transition from a reference rate regime centred on interbank offered rates (IBORs) to one based on a new set of overnight risk-free rates (RFRs) is an important paradigm shift for markets. This special feature provides an overview of RFR benchmarks, and compares some of their key...

It is well known that the Cox-Ingersoll-Ross (CIR) stochastic model to study the term structure of interest rates, as introduced in 1985, is inadequate for modelling the current market environment with negative short interest rates. Moreover, the diffusion term in the rate dynamics goes to zero...

This article focuses on the LIBOR manipulation scandal officially revealed by the U.S. and U.K. authorities in June 2012. The article indicates that this scandal is in reality an outcome of the financial efficiency problem in the developed markets along with other reasons. LIBOR is a widely used...
