英文摘要:
In this paper we extend the existing literature on xVA along three directions. First, we enhance current BSDE-based xVA frameworks to include initial margin in presence of defaults. Next, we solve the consistency problem that arises when the front-office desk of the bank uses trade-specific discount curves (CSA discounting) which differ from the discount rate adopted by the xVA desk. Finally, we clarify the impact of aggregation of several sub-portfolios of trades on the xVA-valuation of the resulting global portfolio and study related non-linearity effects.

中文摘要:
在本文中,我们沿着三个方向扩展了关于xVA的现有文献。首先,我们增强了当前基于BSDE的xVA框架,以包括违约情况下的初始保证金。接下来,我们解决了当银行前台使用与xVA前台采用的贴现率不同的特定交易贴现曲线(CSA贴现)时出现的一致性问题。最后,我们阐明了几个交易子投资组合的合并对最终全球投资组合的xVA估值的影响,并研究了相关的非线性效应。
