Contributor(s): Dharshini David | The dollar is the lifeblood of globalisation: China holds billions in reserve for good reason. Greenbacks, singles, bucks or dead presidents, call them what you will, $1.2 trillion worth are floating around right now – and half the dollars in circulation are actually outside of the USA. But what is really happening as these billions of dollars go around the world every day? By following $1 from a shopping trip in suburban Texas, via China’s Central Bank, Nigerian railroads, the oil fields of Iraq and beyond, The Almighty Dollar answers questions such as: why is China the world’s biggest manufacturer – and the US its biggest customer? Is free trade really a good thing? Why would a nation build a bridge on the other side of the globe? Dharshini David (@DharshiniDavid) is an economist and broadcaster.
