英文摘要:
We examine the problem of dynamic reserving for risk in multiple currencies under a general coherent risk measure. The reserver requires to hedge risk in a time-consistent manner by trading in baskets of currencies. We show that reserving portfolios in multiple currencies $\\mathbf{V}$ are time-consistent when (and only when) a generalisation of Delbaen\'s m-stability condition \\cite{D06}, termed optional $\\V$-m-stability, holds. We prove a version of the Fundamental Theorem of Asset Pricing in this context. We show that this problem is equivalent to dynamic trading across baskets of currencies (rather than just pairwise trades) in a market with proportional transaction costs and with a frictionless final period.

中文摘要:
我们研究了在一般一致风险测度下,多币种的动态风险准备金问题。reserver要求通过一篮子货币进行交易,以时间一致的方式对冲风险。我们表明,当(且仅当)Delbaen的m-稳定条件的推广(称为可选的$\\V$-m-稳定)成立时,以多种货币计的储备投资组合$\\mathbf{V}$是时间一致的。在此背景下,我们证明了资产定价基本定理的一个版本。我们证明,这个问题相当于在具有比例交易成本和无摩擦最终期的市场中跨一揽子货币的动态交易(而不仅仅是成对交易)。
