台灣產險業實施風險基礎資本額制度之適當風險係數探討 / An Analysis of Risk Factors of RBC System for Property-Liability Industry in Taiwan連婉儀, Lien, Wan-I Unknown Date (has links)
行政院會於民國八十八年十二月十六日通過保險法修正草案,修正草案中針對強化保險業之監理機制與增進保戶大眾之權益係以強化其資本適足性為其修法目標,所採之方法即建立風險基礎資本額制(Risk-based Capital, RBC)。而保險法修正案於民國九十年六月二十六日業已經立法院三讀通過,基於保險法相關條文規定,RBC制度將於民國九十二年中實施。
另一方面,美國經濟、社會及投資環境和台灣不盡相同,若將此制度直接或稍加修改即套用於台灣,將可能造成不切實際與誤導的作用,其結果不僅可能無法有效規範及避免保險公司失卻清償能力,亦可能因而造成龐大的社會成本,反而和當初建立RBC制度之原意背道而馳。因此,本論文即依循台灣產險業之產業特性制訂一套合宜之產險RBC制度,其中包括各個適當之風險項目及所屬之風險係數。
本論文在資產風險部分結合風險值(Value at risk, VaR)來計算資產之風險係數;在準備金風險以及自留保費收入風險則依照美國RBC制度之原始公式重新計算得來,惟準備金風險部分實因資料取得限制無法順利求出,為求模型完整性此部分本論文以財政部草案取代之;而於自留保費收入風險方面是採險種別及公司別。
研究結果發現:台灣產險的風險係數確實和美國產險的風險係數是有相當的差異,並且須根據台灣產業的經驗及配合我國的社會、經濟、投資環境並經由實際的運算才能得到適切的風險係數;而以論文所建立之RBC模型試算於各公司之風險基礎資本比則多有偏低之情形。 / Legislative Yuan has pass the draft of Insurance Law on June 26, 2001. In order to strengthen insurance regulation mechanism and to protect the insureds' benefit, the Risk-based Capital will be implemented in Taiwan Insurance market in 2003.
On the other way, the economic environment and investment markets in United State are different from those in Taiwan. If we directly imitate their RBC system in Taiwan, the outcome would be impractical. It not only can't regulate the insurers effectively, but also may cause huge social cost. Therefore, the purpose of the thesis is to establish a suitable risk items and suitable risk factors for Property-Liability insurance in Taiwan by our own empirical data.
This study finds that risk factors are significant different between Taiwan and American for Property-Liability insurance industry. The risk factors of the RBC system in Taiwan must depend on our own empirical data. I used the RBC model built in the thesis to test every Property-Liability company in Taiwan, and found that calculated Risk-based Capital ratios were relatively low.

台灣壽險公司資本適足率分析-以Solvency II QIS5原則計算 / A study on the solvency capital requirements of the life insurance companies in Taiwan-estimated in Solcency II QIS5 principles林正國, Lin, Cheng Kuo Unknown Date (has links)
歐盟保險業新監理架構Solvency II 於第5 次量化衝擊研究完成後計畫將在近年正式施行,我國保險業監理制度是否朝採用Solvency II 架構的方向前進仍未為定論,但必頇先行瞭解採行此制度可能對業界造成的影響。
本研究以2010 年8 月時CEIOPS 對Solvency II 所進行的第5 次量化衝擊研究QIS5 設立的標準與原則,對公司的資產與負債做假設後,以公帄價值法衡量壽險公司各部位資產位與負債,包括準備金的公帄價值衡量,並利用QIS5 所提供之計算工具標準法計算四家台灣壽險公司在2009 年底時的清償資本要求SCR。而QIS5 是在金融風暴後不久,當時環境使得利率極低,為了估算在利率環境較正常的情況下,本研究以2007 年底之利率做敏感度分析,重新計算各公司之資產與負債狀況與清償資本要求SCR。
研究結果發現在本研究假設下,負債面的準備金提存不足,保險公司以經濟
資本角度來衡量已經屬於破產狀態。投資型分離帳戶以外的準備金計算與目前準備金計提的方式除了頇以公帄價值衡量保險責任的最佳估計外,另外需要計提風險邊際,此數額約為最佳估計總額的12.4%至30.2%,保險公司自有資本不足有很大的因素是由於此部分準備金的計提。
也發現所計算出的SCR 中所最大的比率為利率風險或匯率風險,在假設以較
高利率環境做敏感度分析後發現壽險公司淨值仍然為負數,且所需要的SCR 與之前所得結果相差不大,顯示壽險公司負債部位對利率敏感度相當高,即使曝險部位變少,對於未來的利率變動仍需要準備相當大的資本以防範虧損。 / After the completion of the Fifth Quantitative Impact Study (QIS5) for the new insurance industrial regulation framework- Solvency II, European Union planned to implement the project in few years. No matter that the regulatory system of insurance industry in Taiwan will follow the trend or will not, it is a must that we should estimate the impacts on the whole industry before making the decisions.
This study have an aim to estimate the Solvency Capital Requirements of 4 life insurance companies in Taiwan in the same principles with QIS5, which were took place in August 2010 by CEIOPS. In order to calculate the SCR, we made a lot of hypotheses and then estimated the fair value of the company assets and liabilities, including the fair value of technical provision. By means of the calculating helpers provided by CEIOPS used in QIS5, we found out the SCRs of these companies when they were on 31 December 2009. Then we performed the sensitivity analysis by the different interest rate which is based on the data on 31 December 2007, and recalculated the SCRs of the companies.
This study had conclusions that the technical provisions were not sufficient to fulfill the obligations in aspect of the economic value. The surplus of companies were exhausted, because the technical provisions increased by fair valuation. Also, the heavy loadings of risk margins as 12.4% to 30.2% of the best estimates were the important reason of the negative own fund.
We found that the capital requirements of interest risk and currency risk took great percentages of total SCRs. And the SCRs will not reduce in great amount caused by technical provisions reduced in the situation that interest rate come back to the level in 2007. It showed that the SCRs had great sensitivity to the interest risk and insurance companies should prepare sufficient own fund to prevent financial crisis caused by interest rate shock.

資本適足率對銀行流動性風險傳遞效果之研究 / The Effect of Capital Requirement on the Transmission of Liquidity Preference Shock among Banks蔡幸芳, Tsai, Hsing Fang Unknown Date (has links)
本研究旨在說明資本適足率對於銀行業資訊傳遞效果之影響,利用Allen and Gale (2000)模型討論在不完整市場結構下,銀行間因為持有銀行同業存款而形成相連的傳染途徑,進而影響整個系統,本研究擴展Allen and Gale (2000)的模型,加入資本適足率的考量,從而進一步探討透過資本適足要求能否有效提高銀行整體穩定性。
模型假設因為不同區域對於早、晚期消費需求不同,可藉由區域間的資源移轉,來達到最適分配情況。隨著資本適足率的納入,將改變最適分配解,同時分析緩衝(buffer)、擴散效果(spillover effect)及傳染(contagion)的變化。文中傳染定義為擴散效果扣除緩衝力道的淨結果,並說明若有超額流動性消費需求衝擊時,一家銀行的倒閉將如何傳染至整個銀行體系。
此研究發現,在資本適足規定下,若長期資產報酬率越大,會更有機會取得較大的緩衝能力,但將面對較大的擴散效果。關於傳染現象,則是發覺當銀行同業存款越小,在資本適足規定下的傳染機會越低;若長期資產的早期報酬率越大,同樣可降低發生傳染現象機率,即驗證資本適足率對於銀行穩定性的貢獻。 / The objective of this study is to testify the effect of capital requirement with regard to information transmission among banks. We develop a model based on Allen and Gale (2000) to discuss that under incomplete market structure, contagion channel is built because of interbank deposits market. We also expand Allen and Gale’s model by putting new parameter, capital requirement, into this model to analyze the impact of capital requirement with respect to stability in banking system.
Due to different liquidity demands at each date in different regions, banks can exchange resources in the system to reach the first-best allocation. With capital requirement, the first-best allocation varies and so does buffer, spillover effect and contagion. In this article, contagion is defined as the net result of spillover effect minus buffer. Besides, we explain how the bankruptcy in one region evolves into the bankruptcy in the whole system under excess demand for liquidity.
We find out that with capital requirement, if return of long-term asset at final date is higher, there will be more chances to have more buffers but larger spillover effect. As for contagion, it shows that with lower interbank deposits or higher return of long-term asset at early date, the possibility of contagion will be reduced. As a result, we can conclude that capital requirement really improves the stability in banking system.

Previous issue date: 2017-12-11 / A iminência da entrada em vigor das regras estabelecidas pelo acordo da Basileia III, motivado pela crise do subprime em 2009, desperta preocupação ao redor do mundo, inspirando inúmeros estudos que tentam antecipar potenciais efeitos desta regulamentação sobre a economia (BERROSPIDE e EDGE, 2010). O Brasil vive uma das piores recessões de sua história e as provisões para créditos ruins nos balanços dos bancos se avolumam, gerando um aumento do estoque de créditos tributários. Em linha com diversos estudos já realizados, este trabalho explorou efeitos decorrentes da implantação do acordo da Basileia III em relação ao capital mínimo regulatório exigido, com o diferencial de dar ênfase ao impacto da exclusão dos créditos tributários da base de capital dos bancos. O objetivo foi identificar se a restrição de capital trazida por tais deduções, no âmbito do novo acordo, poderia impactar o volume de créditos concedidos pelos bancos, impactando, portanto, o processo de recuperação econômica do Brasil. Verificou-se, através de uma pesquisa exploratória, que abordou uma amostra relevante de 38 bancos, que os avanços dos ajustes prudenciais de créditos tributários terão alto impacto sobre a base de capital das instituições financeiras. Tais deduções, geraram impactos em 28 bancos da amostra, chegando a representar mais de 100% da necessidade agregada de capital principal e 59% da necessidade agregada de capital nível 1 dos bancos analisados. Do ponto de vista de influência das deduções dos créditos tributários sobre as carteiras de crédito dos bancos, foi possível constatar que o impacto tende a ser pequeno, chegando a 1,5% de redução sobre o total da carteira de crédito dos bancos analisados. Essa conclusão, apesar de parecer incoerente à primeira vista, justifica-se pela capacidade dos bancos em atrair mais capital, em função de suas rentabilidades acima do custo de capital próprio. Essa análise nos permitiu confirmar a relevância dos créditos tributários das instituições financeiras sobre suas políticas de gestão de capital e verificar que as deduções de créditos tributários, apesar de representar restrições importantes de capital, não deverão impactar de forma relevante o crescimento das carteiras de crédito no sistema financeiro brasileiro. / The imminence of fully application of the rules established by Basel III, motivated by the subprime crisis in 2009, arouses concern around the world, motivating several papers trying to anticipate potential effects of this regulation (BERROSPIDE e EDGE, 2010). Brazil is facing one of the worst recessions in its history and the increase in provisions for bad credits, led to an increase in tax credits in the banks' balance sheets in Brazil. Aligned with several studies, this research explored the effects arising from the implementation of Basel III agreement in relation to minimum regulatory capital, with the differential of emphasizing the impact of the exclusion of tax credits from the capital base of banks. The objective was to identify if the restriction of capital brought by Tax Credits under the new agreement could impact the volume of credits granted by the banks, thus impacting the process of economic recovery in Brazil. It was verified through a relevant sample of 38 banks that tax credits will have a high impact on the banks' capital base. These deductions generated impacts on 28 sample banks, accounting for more than 100% of the aggregate principal capital requirement and 59% of the aggregate capital requirement of the banks analyzed. From the point of view of the influence of tax credit deductions on banks' credit portfolios, it was possible to verify that the impact tends to be small, reaching a reduction of 1.5% on the total loan portfolio of the banks analyzed. This conclusion, despite seeming at first glance to be inconsistent, is justified by the ability of banks to attract more capital, due to their profitability above the cost of equity. This analysis allowed us to confirm the relevance of tax credits of financial institutions on their capital management policies and to verify that deductions of tax credits, despite representing significant capital constraints, should not have a significant impact on the growth of credit portfolios in Brazil.

Analýza nových princípov regulácie Basel III / Analysis of the new Basel III regulatory principlesTurjaková, Anna January 2012 (has links)
The aim of this diploma thesis is to analyse the development of the regulatory framework and its current state according to the latest Basel III framework. The new rules were created as a response to the financial crisis that started in 2007. The framework represents significant increase in quality, amount and transparency of the capital base in comparison with the pre-crisis situation. Basel III has both micro and macroprudential focus. The diploma thesis describes the development and shortcomings of regulatory framework that necessitated revisions of the regulatory rules over time. These rules evolve with the changes in the financial system and the way how financial risks are managed. Although the roots of financial crisis are related to the mortgage-backed securities market, the banking sector played an important role in spreading the problems. Therefore the diploma thesis will also concentrate on fundamental flaws that contributed to the financial crisis. Then the immediate corrective action taken as a response to the financial crisis are described. After that, the Basel III rules are presented in detail. The newest monitoring of the rules carried out by the Basel Committe and cost analysis carried out by IMF including evaluation based on various analyses of Basel III are presented. Basel III has addressed most of the flaws revealed in Basel II. However, some issues still remain unsolved, which can lead to future problems with the financial system stability.

Impacto de la política macroprudencial en la economía peruana: un modelo semi-estructural / The Impact of Macroprudential Policy in Peru: A semi structural ModelOsorio Fernández, André Nicolás 26 November 2020 (has links)
El presente documento investiga los efectos de la política macroprudencial, medida por el requerimiento de capital sobre la economía peruana. Este estudio adapta y estima un modelo semi-estructural a la economía peruana, incorporando un instrumento de política macroprudencial y el sector crediticio. Para su estimación se utilizan datos de frecuencia trimestral y se estima mediante el Método Generalizado de Momentos. Se encuentra que el requerimiento de capital tiene un efecto negativo sobre el crecimiento del crédito y producto, y sobre la inflación. Además, mediante un análisis de escenarios se encuentra que los costos de la política macroprudencial resultan mayores que los de política monetaria. Por último, se encuentran indicios de que la política macroprudencial y monetaria deben coordinarse. / This document investigates the effects of macroprudential policy on the Peruvian economy, measured as the capital requirement ratio. This study adapts and estimates a semi-structural model to the Peruvian economy, incorporating a macroprudential policy instrument and a credit sector. The model is estimated using quarterly frequency data. It is estimated using the Generalized Method of Moments. The capital requirement has a negative effect on the growth of credit and product, and on inflation. Furthermore, through a scenario analysis, it is found that the costs of macroprudential policy are higher than those of monetary policy. Finally, there are signs that macroprudential and monetary policy need to be coordinated. / Trabajo de investigación

Solvency Capital Requirement (SCR) for Market Risks : A quantitative assessment of the Standard formula and its adequacy for a Swedish insurance company / Kapitalbaskrav för marknadsrisker under Solvens II : En kvantitativ utvärdering av Standardformeln och dess lämplighet för ett svenskt försäkringsbolagWiding, Björn January 2016 (has links)
The purpose of this project is to validate the adequacy of the Standard formula, used to calculate the Solvency Capital Requirement (SCR), with respect to a Swedish insurance company. The sub-modules evaluated are Equity risk (type 1) and Interest rate risk. The validation uses a quantitative assessment and the concept of Value at Risk (VaR). Additionally, investment strategies for risk free assets are evaluated through a scenario based analysis. The findings support that the Equity shock of 39%, as proposed in the Standard formula, is appropriate for a diversified portfolio of global equities. Furthermore, to some extent; the Equity shock is also sufficient for a diversified global portfolio with an overweight of Swedish equities. Additionally, the findings shows that the Standard formula for Interest rate risks occasionally underestimates the true Interest rate risk. Furthermore, it’s shown that there are some advantage of selecting an investment strategy that stabilizes the Own fund of an insurance company rather than a strategy that minimizes the SCR. / Syftet med detta arbete är att utvärdera Standardformeln, som används för att beräkna solvenskapitalkravet (SCR) under Solvens II, med avseende på dess lämplighet för ett svensk försäkringsbolag. Modulerna som utvärderas är aktierisk (typ 1) och ränterisk. Utvärderingen genomförs med kvantitativa metoder och utifrån konceptet Value at Risk (VaR). Dessutom utvärderas investeringsstrategier för riskfria tillgångar genom en scenariobaserad analys. Resultaten stödjer att den av Standardformeln föreskrivna aktiechocken på -39 % är tillräcklig för en diversifierad global aktieportfölj. Dessutom är aktiechocken även tillräcklig för en diversifierad global portfölj med en viss övervikt mot svenska aktier. Vidare visar resultaten att Standardformeln under vissa omständigheter underskattar ränterisken. Slutligen visar den scenariobaserade analysen att det är fördelaktigt att välja en investeringsstrategi som stabiliserar Own fund, hellre än en strategi som minimerar SCR.

On some aspects of coherent risk measures and their applicationsAssa, Hirbod 07 1900 (has links)
Le sujet principal de cette thèse porte sur les mesures de risque. L'objectif général est d'investiguer certains aspects des mesures de risque dans les applications financières. Le cadre théorique de ce
travail est celui des mesures cohérentes de risque telle que définie dans Artzner et al (1999). Mais ce n'est pas la seule classe de mesure du risque que nous étudions. Par exemple, nous étudions aussi quelques aspects des "statistiques naturelles
de risque" (en anglais natural risk statistics) Kou et al (2006) et des mesures convexes du risque Follmer and Schied(2002). Les contributions principales de cette
thèse peuvent être regroupées selon trois axes: allocation de capital, évaluation des risques et capital requis et solvabilité.
Dans le chapitre 2 nous caractérisons les mesures de risque avec la propriété de Lebesgue sur l'ensemble des processus bornés càdlàg (continu à droite, limité à gauche). Cette caractérisation nous permet de présenter deux applications dans l'évaluation des risques et l'allocation de
capital. Dans le chapitre 3, nous étendons la notion de statistiques naturelles de risque à l'espace des suites infinies.
Cette généralisation nous permet de construire de façon cohérente des mesures de risque pour des bases de données de n'importe quelle taille. Dans le chapitre 4, nous discutons le concept de "bonnes affaires" (en anglais Good Deals), pour notamment caractériser les situations du marché où ces positions pathologiques
sont présentes. Finalement, dans le chapitre 5, nous essayons de relier les trois chapitres en étendant la définition de "bonnes affaires" dans un cadre plus
large qui comprendrait les mesures de risque analysées dans les chapitres 2 et 3. / The aim of this thesis is to study several aspects of risk measures particularly in the context of financial applications. The primary framework that we use is that of coherent risk measures as defined in Artzner et al (1999). But this is not the only class of risk measures that we study here. We also investigate the concepts of natural risk statistics Kou et al (2006) and convex risk measure Follmer/ and Schied (2002). The main contributions of this Thesis can be classified in three main axes: Capital allocation, risk measurement and capital requirement and solvency. In chapter 2, we characterize risk measures with the Lebesgue property on bounded càdlàg processes. This allows to present two applications in risk assessment and capital allocation. In chapter 3, we extend the concept of natural risk statistics to the space of infinite sequences. This has been done in order to introduce a consistent way of constructing risk measures for data bases of any size. In chapter 4, we discuss the concept of Good Deals and how to deal with a situation where these pathological positions are present in the market. Finally, in chapter 5, we try to relate all three chapters by extending the definition of Good Deals to a larger set of risk measures that somehow includes the discussions in chapters 2 and 3.

[en] MODEL FOR CALCULATING THE NEED FOR CAPITAL TO COVER THE UNDERWRITING RISKS OF NON-LIFE OPERATIONS / [pt] MODELO DE CÁLCULO DA NECESSIDADE DE CAPITAL PARA COBRIR OS RISCOS DE SUBSCRIÇÃO DE OPERAÇÕES NÃO VIDAEDUARDO HENRIQUE ALTIERI 03 May 2019 (has links)
[pt] Importante questão que se coloca atualmente é a capacidade de medição do volume de capital necessário, às sociedades seguradoras, para fazer frente aos diversos tipos de risco que tais companhias suportam no exercício de suas atividades. Esse volume de capital necessário deve ser tal que permita à companhia suportar variabilidades no negócio. As motivações para o desenvolvimento de modelos matemáticos visando à determinação desta necessidade de capital são tanto a preocupação das próprias companhias com a sua gestão de risco, como também aspectos relacionados ao estabelecimento de requerimentos de capital exigidos pelo regulador de seguro às sociedades seguradoras para fazer frente aos riscos suportados. Entre tais riscos, encontra-se a categoria dos riscos de subscrição, relacionados diretamente à operação central de uma seguradora (design de produto, precificação, processo de aceitação, regulação
de sinistros e provisionamento). Esta dissertação apresenta uma proposta de modelo para determinação do volume necessário de capital para fazer frente aos riscos de subscrição, na qual tal categoria de riscos é segregada nos riscos de provisão de sinistros (relativos aos sinistros ocorridos e, assim, relacionados às
provisões de sinistros) e nos riscos de emissão/precificação (relativos aos sinistros à ocorrer num horizonte de tempo de 1 ano, considerando novos negócios). Em especial, o modelo proposto utiliza processos de simulação que levam em consideração a estrutura de dependência das variáveis envolvidas e linhas de
negócio, fazendo uso do conceito de cópulas condicionais. / [en] Important question that arises today is the ability to measure the amount of capital necessary to insurance companies, to cope with various types of risk that these companies support in performing their activities. This volume of capital required must be such as to enable the company to bear variability in business. The motivations for the development of mathematical models aimed at the determination of those capital needs are both the concern of companies with their own risk management, as well as aspects related to establishing capital requirements required by the insurance regulator to insurance companies to face the risks borne. Among such risks, is the category of underwriting risks, directly related to the core operation of an insurance company (product design, pricing, underwriting process, loss settlement and provisioning). This dissertation proposes a model for determining the appropriate amount of capital to cope with the underwriting risks, where such risk category is segregated in reserving risks (relative to incurred events) and pricing risks (relative to events occurring in the time horizon of 1 year, considering new businesses). In particular, the proposed model uses simulation processes that take into account the dependence structure
of the variables involved and lines of business, making use of the concept of conditional copulas.
