英文摘要:
Banks must manage their trading books, not just value them. Pricing includes valuation adjustments collectively known as XVA (at least credit, funding, capital and tax), so management must also include XVA. In trading book management we focus on pricing, hedging, and allocation of prices or hedging costs to desks on an individual trade basis. We show how to combine three technical elements to radically simplify XVA management, both in terms of the calculations, and the implementation of the calculations. The three technical elements are: trade-level regression; analytic computation of sensitivities; and global conditioning. All three are required to obtain the radical efficiency gains and implementation simplification. Moreover, many of the calculations are inherently parallel and suitable for GPU implementation. The resulting methodology for XVA management is sufficiently general that we can cover pricing, first- and second-order sensitivities, and exact trade-level allocation of pricing and sensitivities within the same framework. Managing incremental changes to portfolios exactly is also radically simplified.

中文摘要:
银行必须管理其交易账簿,而不仅仅是对其进行估值。定价包括估值调整,统称为XVA(至少包括信贷、融资、资本和税收),因此管理层也必须包括XVA。在交易账簿管理中,我们专注于定价、套期保值,以及将价格或套期保值成本分配给各个交易台。我们将展示如何结合三个技术元素,从根本上简化XVA管理,包括计算和计算的实现。三个技术要素是:贸易水平回归;灵敏度的解析计算;以及全球条件反射。这三个方面都需要获得根本的效率提升和实施简化。此外,许多计算本身是并行的,适合GPU实现。由此产生的XVA管理方法具有足够的通用性,我们可以在同一框架内涵盖定价、一阶和二阶敏感度,以及定价和敏感度的准确贸易级分配。管理投资组合的增量变化也从根本上得到了简化。
