Relationship between Selic rate and Basel III parameters - A statistics approach and a fuzzy forecasting model

In this work the relationship between the Selic rate and some bank parameters defined by the so-called Basel Accords is studied. The cross-correlation between the Selic rate and the parameters is used to explain how these parameters affect the Selic rate and vice-versa so as to define the predictability of the Selic rate using (some of) these parameters as inputs. A model is then proposed for predicting the Selic rate based on some specific parameters using fuzzy logic ideas, which dealt with a partitioning of the universe of discourse using clusters related to the output data distribution. The proposed model is compared to four other known models in the literature and showed to have better performance in average compared to all other models.

On Approximate Pricing of Spread Options via Conditional Value-at-Risk

It is widely accepted to use conditional value-at-risk for risk management needs and option pricing. As a rule, there are difficulties in exact calculations of conditional value-at-risk. In the paper, we use the conditional value-at-risk methodology to price spread options, extending some approximation approaches for these needs. Our results we illustrate by numerical calculations which demonstrate their effectiveness. We also show how conditional value-at-risk pricing can help with regulatory needs inspired by the Basel Accords.

Value at Risk, Legislative Framework, Crises, and Procyclicality: what goes wrong?

This study highlights some deficiencies of the stock markets’ risk legislation framework, and particularly the CESR (2010) guidelines. We show that the current legislative framework fails to offer incentives to financial management companies to invest in advanced models for more representative Value at Risk (VaR) estimations, and for this reason, in many cases conventional VaR models are applied. We use data from the DAX, CAC 40, FTSE, FTSEMIB and IBEX indices, and then we apply them to the widely accepted Delta Normal VaR model. The empirical findings show that the conventional VaR models not only fail to provide information for the upcoming financial crises, but also contribute to such phenomena as procyclicality and overreaction in the stock market. We suggest additional tests and we empirically show how these tests could reduce the procyclicality issue and promote a more sustainable investment environment. Even though this study is mainly focused on CESR (2010) guidelines, it could be useful for any similar legislative framework, such as the Basel Accords.

Market Risk Model agricolture portfolio value-at-risk

Thinking about this current extreme scenario of stock exchange observed in a world scenario perspective and the related choices for worldbank portfolio investments in Agricolture commodity, this study its based in an advanced economic observation and analisys of the Agricolture commodity in a scenario of portfolio diversification without have the market risk default. This study its based in an advanced financial strategy to define the market model composed of London stock exchange agricolture commodity observed first in a London scenario and second in a Europe scenario and finally in a world scenario. The authorities regulation and the requirements used to define , the mathematical point of view and to describe , the market value at risk point of view , have been standardized in this empirical market model. The commodity scenario observed and the empirical market model defined to observe the max price distortions of the agricolture commodity defined and defined to observe the porfolio value at risk , are in this market model well described and standardized. Authorities are interested in the empirical market model to observe the VaR data because they are interested in a bank’s ability to withstand extreme events. VaR is monitored and is sanctioned by regulators defined in the Basel accords. The observed price are used in a variable choice of number of data price observation of five price for week a data price observation of one prices for week and a data price observation of two price for week and further similar strategies .

Global Bank Capital and Liquidity after 30 Years of Basel Accords

In this paper we analyze the effectiveness of more than 30 years of efforts by international banking supervisors, working together in the Basel Committee on Banking Supervision, to harmonize capital and liquidity standards for internationally active banks. Notwithstanding the great efforts and progress made by international banking supervisors since the financial crisis of 2007–2009, two important issues require further attention. First, although bank capital ratios have been raised significantly since the recent financial crisis, they are still at historically low levels. In a world in which global debt ratios have risen even further during the past decade, this is a worrying signal of fragility in the global financial system. Second, bank liquidity requirements may have become too complex and could also have unintented and unpredictable interaction effects with bank capital requirements.

Risk management practices of specialized banks in Pakistan

The issue of risk management in banks got an important place after the financial crises. Several efforts have been made to improve the risk management and performance of banks including introducing the Basel Accords as well as risk management guidelines by central banks. Consequently, the State Bank of Pakistan has issued risk management guidelines to strengthen the risk management system and to avoid unwanted happening. Specialized banks also play an important role in different sector of economy. As being the part of financial system need is to analyze the degree of Risk Management Practice in these banks also. So this study will be efforts to critically evaluate the specialized banks regarding risk management practices in their operations. Keywords:Risk Management Practices, Specialized banks

A Decade after Lehman: An Assessment of Key Regulatory Responses to the Global Financial Crisis

In September, 2008, the meltdown of the investment bank Lehman Brothers accelerated the Global Financial Crisis, which affected economies and consumers worldwide. As soon as the Global Financial Crisis broke out, governments and legislators recognized the need for macroprudential reform in order to build a resilient financial system. Today, legislators in every major jurisdiction have finalized almost all major reforms that were envisaged once it had become clear that the crisis was also due to regulatory shortcomings. The reforms especially targeted (over-the-counter) derivatives and the equity base of banks. Following an analysis of the reasons for the Global Financial Crisis and the regulatory failures that contributed to its severity this article will discuss two major legislative responses that intend to make the financial system robust – the establishment of a central dearing obligation for over-the-counter derivatives and the revised Basel Accords on capital requirements for banks.
