抵押市场中的FX模型:国外度量、基差曲线和定价公式

FX Modelling in Collateralized Markets: foreign measures, basis curves, and pricing formulae

Nicola Moreni, Andrea Pallavicini

摘要:

我们提出了一个一般推导的无仲裁定价框架的多币种抵押产品。我们将外币融资政策对期权定价的影响包括在内,以便我们能够对以外币表示的现金流和/或抵押品账户的合同进行定价,包括源自外汇市场混乱的融资成本。然后,我们将这些结果应用于不同市场情况下的交叉货币互换定价,以了解如何实现可行的曲线自助程序。我们提出的主要实际问题所产生的方式,市场报价的流动性工具:不确定性的抵押货币和再认购功能。我们讨论的理论要求,实现曲线自举和近似通常采取实际实施的过程。我们还提供了基于真实市场数据的数值示例。

英文摘要:

We present a general derivation of the arbitrage-free pricing framework for multiple-currency collateralized products. We include the impact on option pricing of the policy adopted to fund in foreign currency, so that we are able to price contracts with cash flows and/or collateral accounts expressed in foreign currencies inclusive of funding costs originating from dislocations in the FX market. Then, we apply these results to price cross-currency swaps under different market situations, to understand how to implement a feasible curve bootstrap procedure. We present the main practical problems arising from the way the market is quoting liquid instruments: uncertainties about collateral currencies and renotioning features. We discuss the theoretical requirements to implement curve bootstrapping and the approximations usually taken to practically implement the procedure. We also provide numerical examples based on real market data.
