In this paper we formulate the Risk Management Control problem in the interest rate area as a constrained stochastic portfolio optimization problem. The utility that we use can be any continuous function and based on the viscosity theory, the unique solution of the problem is guaranteed. The...

We present a stochastic simulation forecasting model for stress testing that is aimed at assessing banks’ capital adequacy, financial fragility, and probability of default. The paper provides a theoretical presentation of the methodology and the essential features of the forecasting model on...

The aim of this article is to highlight the importance and effectiveness of stress testing as part of microprudential policy. We focus on microprudential stress testing to assess financial stability, the resilience and solvency of one important private bank in Algeria in the face of liquidity...

During 2008, the sudden widening of credit spreads led to a rapid decrease in the value of many financial assets, revealing a general shortage of capital for many financial institutions, with some critical peaks that required fund injection and public bailouts.The evidence of a substantial...

Financial crisis has shown significant gaps in risk management system in financial institutions. The major critics focused on an inappropriate usage of the innovative financial products with not adequate reflection of capital requirements for their market risks, not adequate valuations of those...

We highlight important and specific characteristics of default risk and methodological implications. In a simulation contrasting independent, Gaussian and Clayton copulas, we also show that joint default probabilities might be a hidden source of risk in conventional portfolio models of default

Regulatory capital for trading book positions includes two components that cover different risks but apply to the same portfolio, one for market risk and one for credit risk. Similar approaches are common in banks’ internal models for economic capital. Although it is known that joint market...

This article presents a stress-testing model for liquidity risks of banks. It takes into account the first- and second-round (feedback) effects of shocks, induced by reactions of heterogeneous banks, and reputation effects. The impact on liquidity buffers and the probability of a liquidity...

Recent developments in Turkish derivatives markets demonstrate the increasing importance of risk management not only for individual banks but also for the entire system. In this context, this study analyzes the counterparty credit risk of OTC derivatives. The analysis is based on a hypothetical...

Risk measurement and pricing of financial positions are based on modeling assumptions, which are common assumptions on the probability distribution of the position's outcomes. We associate a model with a probability measure and investigate model risk by considering a model space. First, we...
