The price of gold is influenced by many factors, the most important of which is the development of American economy. When the American economy develops well, the dollar will be strong and the price of gold will fall. On the contrary, if the American economy is depressed and the dollar is weak, then the price of gold will rise.
Although there is a little gap between the domestic gold price and the international gold price, the gap is not too big. It will also be affected by the international gold price.
