- Jews control the international banking system

This one I’m not sure about. I doubt Jews CONTROL the banking system as if Jews have a monopoly over all banking systems, but I do think Jews do have a heavy influence in this industry. Many top bankers are Jews, many presidents of international banks and CEOs are Jewish themselves. So I do think Jews do heavily influence where money goes, that is the reason for the unflinching money support to Israel from European countries, and the US - Jews are heavily represented in the financial sector, and they will use that to heavily influence economic policies and economic politics. 

But there are banks that do not have any Jews, as top positions or without any positions.   

I learned this tradition of Jews and money go back to how Christians relegated Jews to working as tax collectors and in the banking sector - as these activities were considered dirty and sinful to Christians. Also, Jesus rebuking the Jewish tax collectors and sellers in a holy temple is a common theme in Christianity, and this is what comes to find when Jews come to mind often in the minds of Christians.
