Quotefx forward is more like F(0,T) = S(0) exp( [r_d-r_f-q]*T ) where q is the cross ccy basis. might be +q, depends on the xccy pair. without it you will find your fx fwds won't match mkt. Hm, I did an exercise where I compared [$]S e^{(r_d-r_f)(T-t)}[$] with the market (Reuters quotes). For the vast majority of the cases I saw only very small differencesDo you know btw what the currency forward domestic rho is? Just want to understand the logic.if I start with a value function [$]V = e^{-r_d(T-t)}(F-K)[$] and work it out[$]V = e^{-r_d(T-t)}(F-K) = e^{-r_d(T-t)} (S e^{(r_d-r_f)(T-t)}-K) = S e^{-r_f(T-t)}-K e^{-r_d(T-t)}[$].Then, the derivative with respect to [$]r_d[$] is[$]K (T-t) e^{-r_d(T-t)}[$]Is this the domestic rho for the a currency forward contract?? Is this the way to think of it?
