not sure of the exact numbers nowdays,
but the currency market trades around 14-20 trillion per day..
the stock market is about 14-20 million a day...?
to control the currency market,all you need is about 1-10 million to control the S&P 500 and do it by buying the index for the day you want to control the currency market ,and even dip a few million into the dow futures ,now you just controled the dollar index without touching the dollar,and with it every market in the world, for at least 24 hours...
my point is..its a hell of alot cheaper to to manipulate the currency market by controling the S&P 500..
