Other currencies aren’t a risk – stats.

The obvious advantages for the buck are familiarity and scale. Size matters: Around 40% of global trade is invoiced in dollars, four times larger than the US share of global trade. The greenback accounts for 42% of volume across the SWIFT network for interbank transactions. The yuan’s share is 2%. The euro conducts an impressive 36%, but this is mostly intra-euro zone business between the common currency’s 20 members. The euro’s share of global trade is a more modest 16%. There simply isn’t traction for alternatives to the dollar outside respective domestic zones of influence.
The domestic necessity of controlling one’s own currency hugely outweighs the elusive charms of being part of a supranational network; witness the doubts that still cling to the euro’s fitness for purpose given the economic gaps between its member nations. Until and unless the major Asian powers of India, China, Japan and Korea decide to create a new currency, the dollar will remain the world’s currency of first resort.
