近年来,巨灾频发,巨灾债券已成为国际公认而又行之有效的巨灾风险转移工具。我国自然灾害多发,全国有2/3的国土面积遭受洪水威胁。因此,在我国发行巨灾债券特别是洪水巨灾债券意义重大。而发行巨灾债券的难点便在于债券的合理定价。本文收集了1961年至2009年我国洪水灾害数据,运用Wang两因素模型对其经验估计分布进行了调整,得出了中国市场上一年期洪水巨灾债券的价格。以期对我国臣灾债券的合理定价有所借鉴。最后,文章针对中国发行洪水巨灾债券的细节方面提出了建议。 相似文献

我国是世界上自然灾害发生较为频繁的国家之一,由于自然灾害的偶发性和不可预测性,往往会带来较大的经济损失和社会危害。巨灾债券作为巨灾风险证券化产品,能够有效弥补巨灾保险的不足,分散巨灾风险,降低巨灾造成的损害,在我国有着广阔的市场前景。巨灾债券进行市场化运营的关键在于定价是否准确。本文利用广东省1983年至2017年间的台风损失数据和1951年至2017年间的台风登陆次数数据,基于非寿险精算和蒙特卡洛模拟方法进行巨灾损失分布和发生次数的拟合,运用Wang两因素模型对台风巨灾债券定价进行实证分析。研究结果表明,巨灾债券价格随着触发概率的下降而上升,保障型债券比无保障型债券价格更高。由上述研究结论带来的启示:第一,建立健全巨灾损失数据库,为巨灾债券定价提供数据支撑;第二,加大财政支持力度,建立巨灾债券融资担保制度;第三,完善相关法律法规和监管制度,为巨灾债券提供制度保障。 相似文献

近年来,我国自然灾害的频频发生,要求我国在建立起完善的巨灾保险制度的同时应当将巨灾风险分散化。当前,许多发达国家在巨灾风险证券化上已有很多成功案例,本文通过对日本巨灾债券的研究来获取国外巨灾风险证券化的经验,用以分析我国巨灾风险的分散化。 相似文献

我国应发展巨灾债券以分散巨灾风险 总被引:2,自引:0,他引:2
巨灾风险具有极强的防灾防损需求,但是一旦出险,保险公司面临巨额赔付,威胁着保险公司的经营.因此,通过保险市场与资本市场的结合,推出保险衍生产品,可以优化风险配置,有效转嫁风险. 相似文献

利率和汇率两种重要政策工具通过影响国民经济增长速度对保险需求产生影响,并通过作用于保单预定利率及投资收益率直接影响着保险企业经营状况及资本充足率。其中,利率的不利变动对保险企业的影响更大,甚至可能危机企业的生存,中国寿险业严重的利差损负担即源于保单预定利率的降低;因地域及目的的不同,汇率对保险企业的影响比较复杂,企业可主动采取的风险防范措施较多。保险企业应加强人才引进和培养,强化对利率、汇率变动趋势的研究,防患于未然;并积极开拓投资渠道,创新风险管理方法,做好资产负债匹配。 相似文献

This study evaluates 10-year US government bond yield forecasts and three-month US Treasury bill rate forecasts for the period between October 1989 and December 2004. In total, 136 forecast time series with approximately 13,800 forecast data were scrutinized, making this the most extensive analysis of interest rate forecasts to date. Not one of the forecast time series proved to be unbiased. In the majority of cases, information from the past was not efficiently integrated into the forecasts. The sign accuracy is significantly better than random walk forecasts in only a very few of the forecast time series. The modified Diebold–Mariano test for forecast encompassing reveals that the information content of most of the forecast time series is lower than that of the naïve forecasts, the simple ARIMA models, the implicit forward rates, or average interest rate expectations. The forecasting process is dominated by the present and past market situation. 相似文献

We propose a new method to calibrate the Vasicek and Cox--Ingersoll--Ross interest rate models from bond prices. We define an appropriate generating function and derive recursive relations between the derivatives of the generating function and the bond prices. The parameters of the Vasicek and CIR models are then obtained by solving a system of linearly independent equations arising from the recursive relations. We include numerical results that show the method’s accuracy when bond prices generated from the exact formulas are used. 相似文献

We provide closed-form expressions for bond prices in interest rate models based on compact Lie groups. Our approach uses a Doob transform technique and PDE solutions by the Mathieu periodic functions. As a by-product, we derive formulas for bond option prices as well as new identities for the Laplace transform of periodic functionals of Brownian motion and Brownian diffusion processes. 相似文献

We explore from a theoretical and an empirical perspective the value of convexity in the US Treasury market. We present a quasi-model-agnostic approach that is rooted in the existence of some affine model capable of recovering with good accuracy the market yield curve and covariance matrix. As we show, at least one such model exists, and this is all we require for our results to hold. We show that, as a consequence, the theoretical ‘value of convexity’ purely depends on observable features of the yield curve, and on statistically determinable yield volatilities. We then address the question of whether the theoretical convexity is indeed correctly reflected in the shape of the yield curve. We present empirical results about the predictive power of a strategy based on the discrepancies between the theoretical and the predicted value of convexity. By looking at 30 years of data, we find that neither the strategy of being systematically long or short convexity (and immunized against ‘level’ and ‘slope’ risk) would have been profitable. However, a conditional strategy that looks at the difference between the ‘implied’ and the statistically estimated value of convexity would have identified extended periods during which the proposed approach would have delivered attractive Sharpe Ratios. 相似文献

中国的股票价格波动及货币政策反应 总被引:9,自引:0,他引:9

本文在阐述中国的股票价格波动情况及成因的基础上,分析中国股票价格的信息功能,并对中国的股票价格与各层次货币供应量进行协整和Granger因果检验。结果表明,从总体上看,中国的股票价格在1995年之后,具备一定的信息功能;股票价格与各层次货币供应量之间存在协整、因果关系。由此,货币当局应对股票价格波动做出反应。文章以前瞻性利率规则为基础,运用IS—PC—AP模型,采用GMM法估计出中国包含股票价格因素的货币政策反应函数。 相似文献
