The position of the US dollar in the global league table of foreign exchange reserves held by other countries is closely watched. Every slight fall in its share is interpreted as confirmation of its imminent demise as the preferred global currency for financial transactions.
The recent drama surrounding negotiations about raising the limit on US federal government debt has only fuelled these predictions by “dollar doomsayers”, who believe repeated crises over the US government’s borrowing limit weakens the country’s perceived stability internationally.
But the real foundation of its dominance is global trade – and it would be very complicated to turn the tide of these many transactions away from the US dollar.
The international role of a global currency in financial markets is ultimately based on its use in non-financial transactions, especially as what’s called an “invoicing currency” in trade. This is the currency in which a company charges its customers.
