<prompt> Human: Was thinking of buying some USDIDR futures to lock in rates but its hard to find a good broker doing this. Any help is appreciated :  <response>: Futuresoptions will protect you against surprise changes, but not slow consistent changes. The person on the other end of the deal is not a charity. They will charge you a premium large enough so that they expect to come out ahead given the consistent change.If your dads job doesnt keep up with local inflation which is what this comes down to--the consistent change in exchange rate is driven by the consistently higher inflation then the only real solution is to change jobs.
