Traditional derivatives pricing theory is based on the assumption that trading desks can lend and borrow at some risk-free rate. Since the credit crunch in 2007, there has been a divergence between government rates, bank funding rates, repo rats, LIBOR rates and overnight rates. To mitigate counterparty credit risks, derivatives have been increasingly collateralized in the interbank market since. We therefore present a consistent pricing framework taking into account different funding assets and collateral schemes as well as risky assets for which a repo market may exist. The current multiple-curve reality in the interest rates market is analyzed in detail for uncollateralized and perfectly collateralized derivatives. Different multiple-curve models from recent papers are recalled, extended and embedded into a consistent framework. Valuation formulas for swaps, forward rate agreements, caps, swaptions and futures are derived in different multiple-curve LIBOR market models. We discuss various dynamics of the forward rates associated with the discounting curve as well as various dynamics of the forward spread between a one-period swap curve and the discounting curve. The considered models could be used for pricing products where a deterministic basis spread is too simplistic, despite the fact that the market does not readily quote volatilities and correlations of OIS rates.
