摘要

信用违约掉期(CDS)是无资金的,或者说是信用风险敞口的合成形式,而债券是资金充足的,因此是现金形式。借用这个行业术语,信用估值调整(CVA)可以被看作是综合的,因为它被定义为通过CDS购买交易对手风险敞口违约保护的现值。本文提出了交易对手风险的现金形式——现金CVA。它直接与交易对手的高级无担保债券曲线挂钩,因此不再需要回收率和CDS曲线输入。由于2007-2008年金融危机后,交易商银行大量退出CDS交易业务,单名CDS不再具有流动性,而由于公司债券电子交易的进步,债券流动性得到了显著改善,因此有必要用现金CVA取代CVA。

Cash CVA -- Credit Valuation Adjustment in the Cash Form
Credit default swaps (CDS) are unfunded, or the synthetic form of credit exposure, while bonds are fully funded, thus the cash form. Borrowing this industry jargon, credit valuation adjustment (CVA) would be seen synthetic, because it is defined as the present value of buying a default protection on counterparty exposure through CDS. This article presents the cash form of counterparty risk, Cash CVA. It links directly to counterparties’ senior unsecured bond curves, thus no longer requiring recovery rate and CDS curve inputs. Replacing CVA with cash CVA is necessitated, because single name CDS is no longer liquid following massive dealer-bank exit from CDS trading business post the Financial Crisis of 2007-2008, while bond liquidity has significantly improved due to advances in corporate bond electronic trading.
