英文摘要:
Credit (CVA), Debit (DVA) and Funding Valuation Adjustments (FVA) are now familiar valuation adjustments made to the value of a portfolio of derivatives to account for credit risks and funding costs. However, recent changes in the regulatory regime and the increases in regulatory capital requirements has led many banks to include the cost of capital in derivative pricing. This paper formalises the addition of cost of capital by extending the Burgard-Kjaer (2013) semi-replication approach to CVA and FVA to include an addition capital term, Capital Valuation Adjustment (KVA, i.e. Kapital Valuation Adjustment to distinguish from CVA.) The utilization of the capital for funding purposes is also considered. The use of the semi-replication approach means that the flexibility around the treatment of self-default is carried over into this analysis. The paper further considers the practical calculation of KVA with reference to the Basel II (BCBS-128) and Basel III (BCBS-189) capital regimes and their implementation via CRD IV. The paper also assesses how KVA may be hedged, given that any hedging transactions themselves lead to regulatory capital requirements and hence capital costs. Finally a number of numerical examples are presented to gauge the cost impact of KVA on vanilla derivative products.

中文摘要:
信用(CVA)、借记(DVA)和融资估值调整(FVA)现在是对衍生品组合价值进行的常见估值调整,以考虑信用风险和融资成本。然而,最近监管制度的变化和监管资本要求的增加导致许多银行将资本成本纳入衍生品定价。本文通过将Burgard Kjaer(2013)的半复制方法扩展到CVA和FVA,使资本成本的增加正式化,包括增加资本期限、资本估值调整(KVA,即资本估值调整,以区别于CVA)此外,还应考虑将资本用于融资目的。半复制方法的使用意味着围绕自我违约处理的灵活性被带入了该分析中。本文进一步考虑了参考巴塞尔协议II(BCBS-128)和巴塞尔协议III(BCBS-189)资本制度及其通过CRD IV实施的KVA的实际计算。鉴于任何对冲交易本身会导致监管资本要求,从而导致资本成本,本文还评估了如何对冲KVA。最后给出了一些数值例子,以评估KVA对香草衍生产品的成本影响。
