本文构建了基于银行监管资本和破产成本的存款保险定价模型.根据理论模型,本文测算了2011年到2017年中国16家上市银行的存款保险费率.结果表明,五大国有银行的存款保险费率要显著低于股份制商业银行和城市商业银行的存款保险费率,但是股份制商业银行的存款保险费率高于城市商业银行的存款保险费率.另外,本文对相关重要参数进行了数值模拟,模拟结果表明,存款保险费率随着监管资本比率和被保险存款比率的提高而下降,随着利率和破产成本的上升而上升.  相似文献

运用存款保险的期望损失定价方法和Shapley值法,建立了考虑银行违约/破产外部效应的存款保险定价模型。模型中度量的破产成本不仅考虑了银行破产清算过程中其自身资产价值的损失,还考虑了银行违约/破产的负外部效应——可能增加其他银行的破产损失,据此确定的存款保险保费反映了各银行对系统总破产成本的边际贡献。为验证模型效果,构造了三种情景进行模拟分析,结果表明:存款保险保费与银行系统对破产银行资产的收购能力负相关,且负相关程度随经济形势的恶化而加剧;保费与整个银行系统参保银行数目之间也呈负相关关系。  相似文献

资本充足率、存款保险费率是发达国家普遍采用的维持银行稳定的基本措施,一般来说资本充足率越高,则所需的存款保险费率越低,银行为减小成本,都希望在合理控制风险的前提下减少所缴纳的存款保险.本文使用根据期权思想建立的存款保险定价模型,推导了存款保险费率对资本充足率的敏感性系数;其次根据中国上市银行的数据进行测算,分别计算了14家银行每增加一个单位的资本充足率可降低存款保险费率的数额,并对实证的结果进行比较;最后给出相关结论.  相似文献

受到现有的存款保险定价模型适用条件的限制,已有的存款保险定价方法无法适用于我国多数的中小商业银行,而这些银行往往是风险较高需要存款保险机构重点关注的对象。为破解这一难题,依据银行损失分布、资产配置与存款保险定价的关系,提出了基于单位资产损失分布来测算存款保险费率的新思想,并将信用资产组合风险的度量与存款保险定价结合在一起,给出了测算单位资产损失分布的新方法。该方法从构造贷款组合损失的矩母函数入手,采用鞍点法求解贷款组合的损失分布,进而测算单位资产的损失分布,用于测算商业银行的存款保险费率。算例分析表明,该方法突破了原有定价模型在数据条件上的限制,所依赖的数据均来自商业银行公开的信息披露和监管数据,适用于所有的商业银行,具有广阔的应用前景。  相似文献

基于相对VaR的信用担保两期定价模型   总被引:1,自引:0,他引:1  
基于风险价值(VaR)计量模型的信用担保定价方法包括绝对VaR和相对VaR两种方法.对于贷款期限一年以上的风险衡量,相对VaR比绝对VaR更加准确和接近现实.针对现有研究中基于绝对 VaR的只考虑原债务期的信用担保风险计量模型的缺陷,本文采用相对VaR方法,建立了既考虑企业对银行的原债务期风险,又考虑企业对担保机构的债务展期风险的信用担保两期定价模型,从而使基于VaR模型的信用担保定价方法更加科学合理.  相似文献

完全市场上的保险定价问题是人们比较熟悉的研究内容,但它不符合市场实际.本文在不完全市场上研究保险定价的问题.通过对累积保险损失的分析,建立在累积赌付下的保险定价模型;基于对一个无风险资产和有限多个风险资产的投资,建立保险投资定价模型.通过变形,得到相应的保险价格的倒向随机微分方程,并利用倒向随机微分方程的理论和方法,得到了相应的保险价格公式.最后,给出释例进行了分析.本文的研究,不用考虑死亡率、损失的概率分布等因素,为保险定价提供了新的思路,丰富了有限的保险定价方法.  相似文献

PPP项目具有的“大而不倒”特性,致使其陷入财务困境时,政府不得不介入和对其进行救助。然而这种救助必然会扭曲PPP项目定价和加剧市场的不正当竞争。为对冲PPP项目资本短缺的风险及抑制项目“大而不倒”负面效应,建议社会资本方发行或有可换债(CEBs)。CEBs在可换债的基础上引入或有可转债的条款,使其具有危机救助功能和风险转移功能。且CEBs的发行不会增加项目运营公司的公司债务。只有当项目因资本短缺而陷入财务困境时,社会资本方可以通过CEBs转为项目特定收益权和债务减记的方式来增加可支配资本,以维持PPP项目正常运营。研究表明,CEBs通过类似保险的形式对冲项目的资本短缺的风险;为社会资本提供合理的退出机制;对冲政府的裸露头寸。  相似文献

We develop a deposit insurance pricing model that explicitly considers regulatory capital and bankruptcy costs. Based on the pricing deposit insurance model, we calculate the deposit insurance premiums of China's 16 listed banks with time span of 2011 to 2017 in this paper. The results demonstrate that the deposit insurance premiums of state-owned banks is lower than joint-stock commercial banks and city commercial banks, however, the deposit insurance premiums of joint-stock commercial banks is higher than city commercial banks. Numerical simulation shows that, ceteris paribus, the value of deposit insurance decreases with regulatory capital ratios and the insured deposits ratios, but it increases with interest rate and bankruptcy costs.  相似文献

This paper analyzes the investment decisions of insured banks under fixed-rate deposit insurance. The model takes into account the charter value and allows banks to dynamically revise their asset portfolios. Trade-offs exist between preserving the charter and exploiting deposit insurance. The optimal bank portfolio problem is solved analytically for a constant charter value. In any audit period, banks maximize their risk exposure before some critical time and act cautiously thereafter. The corresponding deposit insurance is shown to be a put option that matures at this critical time rather than at the audit date.  相似文献

Under the Basel II standards, the Operational Risk (OpRisk) advanced measurement approach allows a provision for reduction of capital as a result of insurance mitigation of up to 20%. This paper studies different insurance policies in the context of capital reduction for a range of extreme loss models and insurance policy scenarios in a multi-period, multiple risk setting. A Loss Distributional Approach (LDA) for modeling of the annual loss process, involving homogeneous compound Poisson processes for the annual losses, with heavy-tailed severity models comprised of α-stable severities is considered. There has been little analysis of such models to date and it is believed insurance models will play more of a role in OpRisk mitigation and capital reduction in future. The first question of interest is when would it be equitable for a bank or financial institution to purchase insurance for heavy-tailed OpRisk losses under different insurance policy scenarios? The second question pertains to Solvency II and addresses quantification of insurer capital for such operational risk scenarios. Considering fundamental insurance policies available, in several two risk scenarios, we can provide both analytic results and extensive simulation studies of insurance mitigation for important basic policies, the intention being to address questions related to VaR reduction under Basel II, SCR under Solvency II and fair insurance premiums in OpRisk for different extreme loss scenarios. In the process we provide closed-form solutions for the distribution of loss processes and claims processes in an LDA structure as well as closed-form analytic solutions for the Expected Shortfall, SCR and MCR under Basel II and Solvency II. We also provide closed-form analytic solutions for the annual loss distribution of multiple risks including insurance mitigation.  相似文献

将影响银行资产价值的风险因素分解为系统风险因素和银行特定风险因素,进而在系统风险因素点估计和区间估计的不同预期下测算银行存款保险费率水平,得到的费率能够反映银行资产风险随经济形势波动的变化情况。通过模拟测算了我国16家上市银行2008~2016年间特定经济形势情境下的存款保险费率水平,并在极端压力下与传统Merton费率进行了比较。得到的基本结论包括:不同年度不同银行费率对系统风险因素的敏感程度不同;经济形势尾部极端分布对费率的影响具有非对称性特点,风险极高区间对费率的贡献远大于风险极低区间;与传统的Merton费率相比,系统风险特定预期下测算的费率更契合经济形势的变化,这在存款保险制度运行初期,有利于增强基金的抗压能力。  相似文献

In this paper, we provide a new insight to the previous work of Briys and de Varenne [E. Briys, F. de Varenne, Life insurance in a contingent claim framework: Pricing and regulatory implications, Geneva Papers on Risk and Insurance Theory 19 (1) (1994) 53–72], Grosen and Jørgensen [A. Grosen, P.L. Jørgensen, Life insurance liabilities at market value: An analysis of insolvency risk, bonus policy, and regulatory intervention rules in a barrier option framework, Journal of Risk and Insurance 69 (1) (2002) 63–91] and Chen and Suchanecki [A. Chen, M. Suchanecki, Default risk, bankruptcy procedures and the market value of life insurance liabilities, Insurance: Mathematics and Economics 40 (2007) 231–255]. We show that the particular risk management strategy followed by the insurance company can significantly change the risk exposure of the company, and that it should thus be taken into account by regulators. We first study how the regulator establishes regulation intervention levels in order to control for instance the default probability of the insurance company. This part of the analysis is based on a constant volatility. Given that the insurance company is informed of regulatory rules, we study how results can be significantly different when the insurance company follows a risk management strategy with non-constant volatilities. We thus highlight some limits of the prior literature and believe that the risk management strategy of the company should be taken into account in the estimation of the risk exposure as well as in that of the market value of liabilities.  相似文献
