Abstract [en]

This thesis provides an end-to-end picture of the modelling of interest rates and Foreign Exchange (FX) rates. We start by defining the FX rates and the interest rates. After having a good understanding of the basics, we take a deep dive into the approaches commonly used to model interest rates and FX rates respectively. In particular, we present an interest rate model and a FX rate model that I have developed for man- aging Swedbank’s Counterparty Credit Risk (CCR). In addition to the mathematical derivations, we describe the theories underlying the models, discuss the model com- parisons, and explain the model choices made in practical applications. Finally, we provide a prototype of model implementation to illustrate how theory can be put into practice.

I had some doubts about the interest rate model and the FX rate model that I have developed for managing Swedbank’s CCR. These doubts have been cleared up through this thesis work. Both the doubts and the clarifications are described in this thesis.

Abstract [sv]

Denna uppsats tillför en helhetsbild av modellering av räntorna och valutakurserna. Vi börjar med att definiera räntorna och valutakurserna. Med en bra uppfattning av grunden, gör vi en djupdykning i de metoder som används för att modellera räntorna och valutakurserna respektive. I synnerhet presenterar vi en räntemodell och en valu- takursmodell, som jag har utvecklat för att hantera Swedbanks motpartsrisk. Förutom de matematiska härledningarna beskriver vi också modellernas underliggande teorier, diskuterar modellerjämförelser, och förtydligar de modellval som gjorts i praktiska tillämpningar. Slutligen använder vi en prototyp för att belysa genomförandet av modellerna.

Jag var en smula tveksam till de riskfaktormodeller som jag har utvecklat för att hantera Swedbanks motpartsrisk. Jag har klargjort dessa tvivel genom att arbeta med den här uppsatsen. Både tvivlen och klargörandena beskrivs i denna rapport.
