we have 200$billion forex ,for 1$ we have 5RS loss for 200$ billion we have Rs 1 trillion as per ratio 1:5 now Rs 1 trillion = 25$ billion
so the moral of the story is if we have more forex in terms of dollars they changing statics will affect in other way reducing our forex
in long term american economy will not be affected they have kept their tresures in terms of gold u see once dollar loses its 20% value it will rebound all countries forex reserves will compensate the loss as they have accumulated trillions of dollars
