英文摘要:
The inclusion of DVA in the fair-value of derivative transactions has now become standard accounting practice in most parts of the world. Furthermore, some sophisticated banks are including an FVA (Funding Valuation Adjustment), but since DVA can be interpreted as a funding benefit the oft-debated issue regarding a possible double-counting of funding benefits arises, with little consensus as to its resolution. One possibility is to price the derivative by replication, guaranteeing a consistent inclusion of costs and benefits. However, as has recently been noted, DVA is (at least partially) unhedgeable, having no exact market hedge. Furthermore, current frameworks shed little light on the controversial question, raised by Hull (2012), of whether the effect a derivative has on the riskiness of an institution\'s debt should be taken into account when calculating FVA. In this paper we propose a solution to these two problems by identifying an instrument, a fictitious CDS written on the hedging counterparty which is implicitly contained in any given derivatives transaction. This allows us to show that the hedger\'s unhedged jump-to-default risk has, despite not being actively managed, a well defined value associated to a funding benefit. Carrying out the replication including such a CDS, we obtain a price for the derivative consisting of its collateralized equivalent, a contingent CVA, a contingent DVA, and an FVA, coupled to the price via the hedger\'s short-term bond-CDS basis. The resulting funding cost is non-zero, but substantially smaller than what is obtained in alternative approaches due to the effect the derivative has on the recovery of the hedger\'s liabilities. Also, price agreement is possible for two sophisticated counterparties entering a deal if their bond-CDS bases obey a certain relationship, similar to what was first obtained by Morini and Prampolini (2010).

中文摘要:
在世界大部分地区,将DVA纳入衍生产品交易的公允价值已成为标准会计惯例。此外,一些成熟的银行正在纳入FVA(融资估值调整),但由于DVA可以被解释为一种融资收益,因此出现了经常辩论的关于可能重复计算融资收益的问题,对其解决方案几乎没有共识。一种可能性是通过复制为衍生产品定价,保证成本和收益的一致性。然而,正如最近所指出的,DVA(至少部分)是不可对冲的,没有确切的市场对冲。此外,Hull(2012)提出了一个有争议的问题,即在计算FVA时,是否应该考虑衍生工具对机构债务风险的影响,目前的框架对这个问题几乎没有什么帮助。在本文中,我们提出了一个解决这两个问题的方法,通过识别一种工具,一种写在对冲对手上的虚拟CDS,它隐含在任何给定的衍生品交易中。这使我们能够表明,尽管没有积极管理,但套期保值者的未对冲跳转违约风险具有与融资收益相关的明确价值。进行包括此类CDS在内的复制,我们获得衍生工具的价格,包括其抵押等价物、或有CVA、或有DVA和FVA,并通过套期保值者的短期债券CDS基础与价格耦合。由此产生的融资成本不为零,但由于衍生工具对套期保值者负债的回收产生影响,因此大大小于通过替代方法获得的融资成本。此外,如果两个成熟的交易对手的债券CDS基础服从某种关系,那么他们就有可能达成价格协议,这类似于莫里尼和普兰波利尼(2010)首次获得的结果。
