Two-factor interest rate model is calibrated to market data and used for the simulation of future interest rate paths. We find that the model is able to fit well to market data.
The default probabilities for each counterparty are directly extracted from CDS market quotes.

We assume no correlation between the default times of the counterparties. Chapter 1 Introduction One of the major causes of the financial crisis from was the underestimation of the credit risk importance.
Before this point in time, the standard practice of pricing derivatives contracts was to mark them to the market without taking the counterparty credit risk into account. Future cash flows were simply discounted back using the LIBOR curve and the subsequent values were considered for default-free.
Nowadays, financial institutions recognize the importance of the possibility of futures losses due to counterparty default when pricing derivative contracts. Moreover, regulators impose further restrictions on the specifics related to derivatives trading.
One differentiates from the other by the fundamental assumption of whether only one or both counterparties may default. The question which gives better approximation of the credit risk price is still debatable.
Moreover, the complexity of calculating Thesis cva is also due to the challenging nature of its components. Many interest rate models have been used in the past for the simulation of future exposures.
However, in the current global economic situation, where negative interest rates are no longer a myth, some of the models are considered market inconsistent. Brigo and Mercurio introduce the Linear Gaussian Two Factor model which overcomes this modelling disadvantage by being able to produce negative values for the yield curve evolution.
We calibrate the model to At-the-money European swaption prices. Another important step of computing CVA is the choice of credit modelling approach. Producing default probability curve which incorporates the possibility of random shocks is replicated by the times of Poisson process jumps.
As those jumps are exogenous, introducing model dependency on market factors is challenging and has not been considered in this thesis. This thesis is organized as follows.
In Chapter 2 we define counterparty credit risk and credit value adjustment and discuss the component of the CVA.
Chapter 3 is devoted to the interest rates modelling, the nature of the Linear Guassian two factor model and its application for mark to market pricing of interest rate contracts. In Chapter 4 we review the literature on credit modelling frameworks and discuss the choice of intensity function for producing default probability curves.
Chapter 6 closes with the numerical results for the CVA of Bermudan swaptions and compares the measure among different counterparties. A loss occurs if at the default time the contract has a positive value for the other counterparty. For many years, contracts over-the-counter have been priced without consideration of the credit risk.
However, after the financial crisis fromit has become clear that managing counterparty credit risk cannot be neglected anymore.
Thus, it measures the difference between the risky and the default-free price of the derivative contract. Under the unilateral framework, it is assumed that the counterparty which performs the CVA analysis is default-free.
Both counterparties require premium for the risk they are bearing, therefore, they could not agree on the credit risk price under the unilateral framework. Under the bilateral CVA approach, both the bank and the counterparty could default. Under both unilateral and bilateral frameworks, pricing counterparty credit risk is not easy, especially when the target is an exotic derivative contract or a portfolio of exotic products.
When a simple contract is present, such as a coupon paying bond, one should simply account for the possibility of default when calculating the discounted value of the cash flows.CLINICAL AND HISTOLOGICAL CORRELATIONS IN ISCHEMIC STROKES.
