巴塞尔协议II下操作风险资本模型的损失分布方法:结合不同数据源进行风险估计

Loss Distribution Approach for Operational Risk Capital Modelling under Basel II: Combining Different Data Sources for Risk Estimation

Pavel V. Shevchenko, Gareth W. Peters

摘要:

在过去十年中,由于操作风险环境的重大变化,银行业的操作风险管理发生了重大变化。全球化、放松管制、使用复杂的金融产品以及信息技术的变化,导致人们面临与市场和信用风险截然不同的新风险。作为回应,巴塞尔银行监管委员会制定了一个监管框架,称为巴塞尔II,其中引入了操作风险类别和相应的资本要求。在过去五年中,世界大多数地区的主要银行通过采用损失分布方法获得了《巴塞尔协议二》高级计量方法的认证,尽管在实施过程中存在一些尚未解决的方法学挑战。不同的方法和途径仍在激烈的争论中。在本文中,我们回顾了文献中提出的方法,结合不同的数据源(内部数据,外部数据和情景分析),这是AMA的监管要求之一。

英文摘要:

The management of operational risk in the banking industry has undergone significant changes over the last decade due to substantial changes in operational risk environment. Globalization, deregulation, the use of complex financial products and changes in information technology have resulted in exposure to new risks very different from market and credit risks. In response, Basel Committee for banking Supervision has developed a regulatory framework, referred to as Basel II, that introduced operational risk category and corresponding capital requirements. Over the past five years, major banks in most parts of the world have received accreditation under the Basel II Advanced Measurement Approach (AMA) by adopting the loss distribution approach (LDA) despite there being a number of unresolved methodological challenges in its implementation. Different approaches and methods are still under hot debate. In this paper, we review methods proposed in the literature for combining different data sources (internal data, external data and scenario analysis) which is one of the regulatory requirement for AMA.
