It will not come as news to anyone that the US dominates the world economically and militarily. But the exact mechanisms by which American hegemony has been established and maintained are perhaps less well understood than they might be. One tool used to great effect has been the dollar, but its efficacy has recently been under threat since Europe introduced the euro.
The dollar is the de facto world reserve currency: the US currency accounts for approximately two thirds of all official exchange reserves. More than four-fifths of all foreign exchange transactions and half of all world exports are denominated in dollars. In addition, all IMF loans are denominated in dollars.
But the more dollars there are circulating outside the US, or invested by foreign owners in American assets, the more the rest of the world has had to provide the US with goods and services in exchange for these dollars. The dollars cost the US next to nothing to produce, so the fact that the world uses the currency in this way means that the US is importing vast quantities of goods and services virtually for free.
Since so many foreign-owned dollars are not spent on American goods and services, the US is able to run a huge trade deficit year after year without apparently any major economic consequences. The most recently published figures, for example, show that in November of last year US imports were worth 48% more than US exports1. No other country can run such a large trade deficit with impunity. The financial media tell us the US is acting as the 'consumer of last resort' and the implication is that we should be thankful, but a more enlightening description of this state of affairs would be to say that it is getting a massive interest-free loan from the rest of the world.
While the US' position may seem inviolable, one should remember that the more you have, the more you have to lose. And recently there have been signs of how, for the first time in a long time, the US may be beginning to lose.
