英文摘要:
Haircutting non-cash collateral has become a key element of the post-crisis reform of the shadow banking system and OTC derivatives markets. This article develops a parametric haircut model by expanding haircut definitions beyond the traditional value-at-risk measure and employing a double-exponential jump-diffusion model for collateral market risk. Haircuts are solved to target credit risk measurements, including probability of default, expected loss or unexpected loss criteria. Comparing to data-driven approach typically run on proxy data series, the model enables sensitivity analysis and stress test, captures market liquidity risk, allows idiosyncratic risk adjustments, and incorporates relevant market information. Computational results for main equities, securitization, and corporate bonds show potential for uses in collateral agreements, e.g. CSAs, and for regulatory capital calculations.

中文摘要:
削减非现金抵押品已成为影子银行系统和场外衍生品市场危机后改革的一个关键因素。本文通过将折减定义扩展到传统的风险价值度量之外,并采用抵押品市场风险的双指数跳跃扩散模型,建立了一个参数折减模型。针对信用风险度量(包括违约概率、预期损失或意外损失标准)解决折减。与通常在代理数据系列上运行的数据驱动方法相比,该模型支持敏感性分析和压力测试,捕获市场流动性风险,允许特殊风险调整,并纳入相关市场信息。主要股票、证券化和公司债券的计算结果显示,在抵押品协议(如CSA)和监管资本计算中有潜在的用途。
