Amid instability of financial markets and macroeconomic situation the necessity of improving bank risk-management instrument arises. New economic reality defines the need for searching for more advanced approaches of estimating banks vulnerability to exceptional, but plausible events. Stress-testing belongs to such instruments. The paper reviews and compares the models of market risk stress-testing of the portfolio of different financial instruments. These days the topic of the paper is highly acute due to the fact that now stress-testing is becoming an integral part of anticrisis risk-management amid macroeconomic instability and appearance of new risks together with close interest to the problem of risk-aggregation. The paper outlines the notion of stress-testing and gives coverage of goals, functions of stress-tests and main criteria for market risk stress-testing classification. The paper also stresses special aspects of scenario analysis. Novelty of the research is explained by elaborating the programme of aggregated complex multifactor stress-testing of the portfolio risk based on scenario analysis. The paper highlights modern Russian and foreign models of stress-testing both on solo-basis and complex. The paper lays emphasis on the results of stress-testing and revaluations of positions for all three complex models: methodology of the Central Bank of stress-testing portfolio risk, model relying on correlations analysis and copula model. The models of stress-testing on solo-basis are different for each financial instrument. Parametric StressVaR model is applicable to shares and options stress-testing;model based on "Grek" indicators is used for options; for euroobligation regional factor model is used. Finally some theoretical recommendations about managing market risk of the portfolio are given.

The Impact

We take advantage of the non-performing loan ratio as the main indicators of credit risk of the commercial bank, make use of the experience of domestic and foreign research, use LOGIT methodology to construct the stress testing model for the macro-economic factors’ impact of China on credit risk of commercial bank, and apply the hypothetical scenario to the test of macro stress in order to make an assessment in quantity for the impact of the macro-economic changes on the credit risk of the commercial bank system. The results show that the stress tests and applied technology can make a contribution to useful reference of credit risk management of the commercial bank of China.

Simple Task

With the current cross-border growth in Islamic finance, Islamic commercial banks (ICBs) are looking forward to being perceived as an industry in the process of becoming mature. This would require the establishment of some basic infrastructure, including sophisticated risk management tools that enhance the soundness and resilience of the ICBS. This paper focuses on the latter that is the role and significance of stress testing as a risk management tool. The stress testing has become part of the regulatory and supervisory authorities within the financial stability analysis. The global financial crisis (2008) has placed the spotlight squarely on stress tests. Though, ICBs operate within the similar financial environment, and their balance sheet composition, however, calls for different treatment in stress testing. Apart from the specificities of ICBs, there are key issues and challenges that should be given due considerations in developing an appropriate stress testing regime. This paper explores key specificities and challenges. The paper argues that in the beginning, conducting the stress testing may not appear a simple task for the ICBs. However, a proper consideration to the challenges identified in the paper would certainly tend to improve the overall effectiveness and credibility of the stress testing programmes.

Determining Factor

The study of the BRVM market risk using the VaR method is a determining factor in assessing the performance of our equity portfolio composed of the BRVM composite index and the BRVM10 index. It has enabled us, with the help of Basel regulations, to use backtesting to determine the minimum amount of capital that an investor must hold per day to protect against risk. The kupiec test enables us to determine the reliability of VaR calculated at different confidence levels. The result of our study confirms, using the extreme VaR method, the robustness of our threshold-based portfolio risk management approach. It also confirms the problem of market attractiveness during times of financial crisis.

Upside Risk

A group of 24 Hawke's Bay hill country farmers are working with service providers to improve the resilience of their farming systems. An important step in the process was to undertake an inventory of their risk management strategies. Farmers were interviewed about their farming systems and risk management strategies and the data was analysed using descriptive statistics. There was considerable variation in the strategies adopted by the farmers to cope with a dryland environment. Importantly, these strategies had to cope with three types of drought and also upside risk (better than expected conditions), and so flexibility was critical. Infra-structure was important in managing a dryland environment. Farmers chose between increased scale (increasing farm size) and geographic dispersion (owning a second property in another location) through to intensification (investing in subdivision, drainage, capital fertiliser, new pasture species). The study identified that there may be scope for further investment in infra-structural elements such as drainage, deeper rooting alternative pasture species and water harvesting, along with improved management of subterranean clover to improve flexibility. Many of the farmers used forage crops and idling capacity (reduced stocking rate) to improve flexibility; others argued that maintaining pasture quality and managing upside risk was a better strategy in a dryland environment. Supplementary feed was an important strategy for some farmers, but its use was limited by contour and machinery constraints. A surprisingly large proportion of farmers run breeding cows, a policy that is much less flexible than trading stock. However, several farmers had improved their flexibility by running a high proportion of trading cattle and buffer mobs of ewe hoggets and trade lambs. To manage market risk, the majority of farmers are selling a large proportion of their lambs prime. Similarly, cattle are either sold prime or store onto the grass market when prices are at a premium. However, market risk associated with the purchase of supplements and grazing was poorly managed.

The Future

This paper deals with the analysis of risks which threaten the future sustainability and operations of agricultural museums in the Czech Republic. In the section on methodology, an applicable risk model has been proposed regarding the condition of museums in the Czech Republic. Using this model, the directors of agricultural museums can assess the most significant risks which may jeopardize the sustainability of museum operations over a three-year period. The greatest risks, according to museum directors, are a lack money for investment, the inability to retain high-quality staff, and issues with technical support for exhibitions. Assessing the importance of risk is positively associated with previous experiences of a particular type of risk, whereas the association of the importance of risk with previous managerial practice is rather inconclusive.

Research Results

The construction materialindustry is one of the most rapidly growing sectors, with many achievements both in Vietnam and in Asia. In recent years, its rapid growth has produced revenues from business activities. One of the key objectives of thispaper is to assess market risk volatility in construction material businesses in the 2012-2014 pre-low inflation period. Our first findings are to be found that beta values in general (< 1) for most of our constructionmaterialcompanies are appropriate when we apply quantitative, statistical and analytical methods to evaluate the asset beta and beta CAPM of 20 listed Viet Nam construction materialcompanies.However, we analyze the market risk volatility, determined byasset and equitybeta var, during the post-low inflation period in thissector and compare results in two circumstances: risk fluctuation in pre-law inflation time 2012-14is lower than that in post-low inflation period 2015-2017.Finally, if we observe in2 periods, BetaCAPM or equity beta mean goes up in case post-low inflation period. At last, policies in risk management and governance are suggested in the conclusion based on the research results and findings. In the post-low inflation environment, we alert that Beta fluctuations could bea little higher.JEL classification numbers:G00, G390, C83
