Zelenka, Jiří ; Brechler, Josef (advisor) ; Gutiérrez Chvalkovská, Jana (referee)
Tato práce se zabývá vztahem mezi výsledky Evropských zátěžových testů 2016 WST) a tržním ohodnocením účastnících se bank, tedy jaký efekt měly výsledky a forma jejich prezentace na investory. První část práce je teoretická a přináší přehled základních informací o zátěžových testech a jejich metodice, dále se zde nachází jak ohlasy, tak i obhajoba WST. Také zde čtenář nalezne alternativní postupy testování bank, využívající metody AQR 2014, CCAR a SRISK, následované přístupů. Druhá část obsahuje přehled stěžejní literatury týkající se zátěžových testů a vlivu zveřejňování jejich výsledků. Třetí část práce se zabývá modelem využívajícím "First Difference" estimátor, který pomocí tří zkoumaných časových úseků analyzuje vliv jednotlivých testovaných faktorů na změny tržních hodnotách bank, které nastaly po zveřejnění výsledků jak EU ostatních testů. Dva modely popisují izolovaný vliv těchto testů po zveřejněních, zatímco poslední model nahlíží na daný časový úsek jako na celek. Výsledky modelů ukazují jen málo signifikantních odhadů, způsobených pravděpodobně Závěrečná kapitola shrnuje získané poznatky doplněné o autorův komentář. Klíčová slova Zátěžové testy, Kapitál, Tržní ohodnocení, EBA, AQR, CCAR, SRISK

Financial Stability Issues and Stress Testing of the Insurance Sector
Hauryliuk, Nadzeya ; Jakubík, Petr (advisor) ; Čech, František (referee)
The purpose of this thesis is to provide an overview of risk and vulnerabilities for financial stability of the European Insurance sector. The methods and principles of risk assessment are examined, as well as their application for the insurance sector. The current macroeconomic situation and its impact on insurers' financial stability is described. Downward changes of interest rates are identified as the biggest current risk. This results from a system-wide stress test conducted by EIOPA (European Insurance and Occupational Pensions Authority), analysis of sensitivities published by several big European Insurers published on a yearly basis and finally from an econometric analysis of the relationship between market data and changes in macroeconomic variables. Keywords financial stability, stress testing, insurance sector, insurance risks

Stress Testing of the Banking Sector
Mohylová, Aneta ; Seidler, Jakub (advisor) ; Džmuráňová, Hana (referee)
This bachelor thesis deals with stress testing of the banking sector as a tool that assesses the resilience of a portfolio, an institution itself or an entire system to adverse macroeconomic development. It aims to provide the reader with general understanding of theoretical aspects of stress testing and its practical application. In the theoretical part, the meaning, purpose and use of stress testing is discussed. Further, stress testing methodology and its limitations are explained and different types of stress tests are mentioned. In the practical part, two hypotheses are tested using vector autoregression model. Firstly, the dependence between loan portfolio quality and selected macroeconomic variables is estimated. Secondly, two types of stress tests are designed in order to test the resilience of the Czech banking sector and individual groups of banks divided according to their size categorization to three adverse scenarios via the most common macroeconomic indicator - capital adequacy ratio. Results suggest high resilience of the Czech banking sector towards adverse macroeconomic development. Powered by TCPDF (www.tcpdf.org)

Four Essays on Financial Stability
Jakubík, Petr ; Dědek, Oldřich (advisor) ; Mejstřík, Michal (referee) ; Kodera, Jan (referee) ; Peltonen, Tuomas (referee)
Recent episodes of financial instability have motivated researchers as well as policy makers to intensify research on financial stability. This thesis contributes to current research and policy discussion by elaborating and empirically testing methodologies, which can be used to measure financial sector vulnerabilities and identify potential risks for financial stability. It further focuses on the link between real and the financial sector as well as possible implications of household financial distress on the aggregate economy. Together with the proposed framework we provide the survey of the current literature on these topics as well as the empirical results. We argue in favour of stress testing methodologies covering the key risks on banks' balance sheets. These frameworks can also be used for emerging markets where data availability is typically limited. It is shown that due to high volatility of credit growth in emerging economies, the static approach assuming constant balance sheet items is not very appropriate. Furthermore, the feedback effect between the financial sector and the real economy might play an important role under certain assumptions, and therefore it should be taken into account by policy makers. This effect can also emerge in the real sector itself as potential instability can...

Stress testing of the banking sector
Procházková, Jana ; Jakubík, Petr (advisor) ; Todica, Doina (referee)
This bachelor thesis deals with stress testing of the banking sector. Stress testing as a risk measurement technique has attracted much attention especially in recent years due to the increased instabilities in financial markets. This work defines two objectives. The aim of theoretical section is to provide a complex survey of stress testing principles and methodologies and to contribute to a better understanding of why stress tests are employed. The empirical section focuses on the credit risk in the Czech Republic. It tries to estimate whether there is an empirical relationship between the quality of credit portfolio of the Czech banking system and the development in key macroeconomic variables. For this purpose the econometric model of vector autoregression has been applied.

Loan Book Credit Risk Stress Testing - Survey on Practice in the Czech Republic
Argayová, Šárka ; Pečená, Magda (advisor) ; Kubíček, Martin (referee)
Stress testing is a general term for framework that assesses possible impact of an adverse shock on the financial health and a capital adequacy of a bank, other financial institution or the whole financial system. Because credit risk is typically the most important risk of a bank and many international surveys describe the credit risk stress testing as one of the least developed, it became the main topic of this thesis. Credit risk stress testing methods developed in the last years very dynamically especially thanks to the requirements on stress testing under the Basel II regulatory framework and a fact that further improvement of these methods is expected to ensure higher financial stability of institutions and financial sector to adverse shocks and enable to withstand severe crisis. The thesis concentrates on the micro level stress tests that are run by each individual bank. It describes the whole credit risk stress testing procedure, Basel II regulatory requirements, the importance of this framework for an institution and offers examples of possible stress testing methods and scenarios. The first significant contribution to the topic is a survey on practice in the mayor Czech banks that analyzes whether they are influenced in their credit risk stress testing framework by their parents or the...

The impact of macroeconomic shocks on credit risk of Slovakian banking sector and its stress testing
Lörinčík, Martin ; Dědek, Oldřich (advisor) ; Kubíček, Martin (referee)
Credit risk tracking and quantification play important roles in risk management and they are not applied only by financial institutions on microeconomic level, but also by central banks on the background of aggregated data. This master thesis deals with the analyses of shocks of given significant macroeconomic variables and their reply on changes of households' and firms' defaulted, non performing loans in Slovakian banking sector. In introductory part, the method of data handling is described, because of their inconsistency in the given field of research. That is caused on one hand by the post-transformational consolidation process of Slovakian banking sector and on the other hand by legislative shifts and changes in calculation methodology of non performing loans. The main aim of the thesis is not to describe and interpret most precisely the economic relations that could influence the level of non performing loans, but the effort to widen the range of credit risk stress testing possibilities in Slovakian banking sector. In order to check the macroeconomic variables' significance, OLS regression is used. Important part of the stress tests is the application of Monte Carlo method which simulates high number of stress scenarios and macroeconomic variables' shocks and therefore helps to improve the...
