Title: Reformulation of the arbitrage-free pricing method under the multi-curve environment
Abstract: This paper proposes a unified framework for the pricing of derivatives under the multi-curve setting. It is shown that any derivative security can be duplicated by using the underlying assets, collateral account and funding account, appropriately. A risk-neutral measure is defined accordingly under which the derivative price is determined uniquely. This idea is extended to the pricing of OIS and LIBOR discount bonds and interest-rate derivatives under the risk-neutral measure, which explains the existence of multiple yield curves simultaneously in the market. Some specific models are given to demonstrate the usefulness of our approach. Through numerical examples, we find that the discrepancy of derivative prices under the multi-curve setting from the classical ones becomes significant when the spread volatility between the collateral and funding rates exceeds some level. Joint work with Y. Muromachi.
