The US dollar remains the backbone of global trade, a status that directly affects the cost and availability of trade finance instruments such as letters of credit and bank guarantees. A recent episode of the BBC podcast 'Rethink' — titled Rethink... the power of the US dollar — features expert analysis on how the dollar achieved this dominance, the risks of over-reliance, and the potential for alternative currencies to reshape international trade.
The Dollar's Central Role in Global Trade
The US dollar is the backbone of global trade and held by governments around the world as a safe haven in times of crisis.
According to the BBC programme, countries such as Ecuador and Panama have adopted the dollar as their official currency, while Argentina has for many years attempted to 'dollarize' its economy. This deep entrenchment means that any shift in confidence in the dollar could have immediate repercussions for trade finance pricing, settlement risk, and currency hedging strategies.
From Bretton Woods to Nixon Shock
The podcast explains how the current system emerged after WWII, when the world order was re-established by tying monetary systems to the value of the dollar, backed by gold. In 1971, President Nixon cut that link to gold, and the entire exchange system has since been tied directly to the dollar itself, its historic success, and access to its financial markets. This event, often called the Nixon Shock, according to the programme, gave the United States what was dubbed an 'exorbitant privilege': the ability to print money without fear of inflation and to build up national debt without consequence.
'Exorbitant Privilege' and Sanctions Power
The podcast notes that dollar dominance also enables the US to impose sanctions on countries and cut off their access to the all-important currency. For trade finance bankers and corporate treasurers, this translates into compliance obligations, restricted market access, and the need for alternative settlement mechanisms when dealing with sanctioned entities. The programme highlights that this power has led some countries, most notably China, to call for the dollar to be replaced as the world's reserve currency.
Challenges to Dollar Dominance
The episode poses critical questions: How difficult would it be to untangle the dollar from global trade? Can any other nations offer the same conditions that have allowed the US currency to thrive? And what would happen if the dollar's role was replaced by newer digital currencies which operate outside traditional government control? These questions are directly relevant to trade finance professionals evaluating long-term FX risk, the viability of non-dollar trade settlement, and the adoption of central bank digital currencies (CBDCs) in cross-border payments.

The programme is presented by Professor Ben Ansell, produced by George Dabby, and edited by Damon Rose. It also draws on archival material from British Pathé, including the 1946 film 'Bretton Woods Money Pact Signed'.
For trade finance practitioners, the podcast underscores that the dollar's role is not immutable. Any credible de-dollarization effort—whether through yuan trade settlement, special drawing rights, or digital currencies—would alter the landscape for trade credit, invoice factoring, and supply chain finance programmes. While the podcast does not forecast a near-term shift, it makes clear that the structural conditions that made the dollar indispensable are being questioned by both state actors and technological innovation.
