Abstract
--------
We propose a general HJM approach to the modeling of multiple yield
curves. In a general semimartingale setting, we model the term structure
of multiplicative spreads between (normalized) FRA rates and simply
compounded OIS risk-free forward rates. We derive HJM drift and
consistency conditions ensuring absence of arbitrage and we show how to
construct models such that spreads are greater than one and ordered with
respect to the tenor's length. When the driving semimartingale is an
affine process, we obtain a flexible Markovian structure which allows for
simple valuation formulas for most interest rate derivatives.
