i was trying to figure out the other day how much cash does fed "have" for market intervention? i mean can it ever run out? i was trying to come out at some number, but could not get to it in any reasonable logical manner. i guess given that USD is reserve currency for 3/4 of worlds oil it probably means that fed "spend" as much money as they deem nesseccary to make sure things are right? anyone know at what point fed's cash runs out?
