A look at how global history, war, and economic policy led Papua New Guinea—and much of the world—to trade in the US Dollar.

Papua New Guinea trades in US Dollars because the currency is the world’s reserve currency, a position it has held since the establishment of the Bretton Woods System in 1944. This global system influences international trade and financial transactions, including PNG’s participation.

In 1944, representatives from 40 nations convened at the Mount Washington Hotel in Bretton Woods, New Hampshire, USA, to create a stable global monetary system after World War II. This meeting, known as the UN Monetary and Financial Conference, was two years in the making and involved extensive discussions among international financial experts. The resulting agreement established the US Dollar as the global reserve currency due to its stability and dominance in international markets. 

The system prioritised paper money over gold reserves to address post-war economic challenges. Gold was reserved for emergencies, while the US Dollar represented the strength of the American economy and was easier to trade internationally. This arrangement also led to the creation of institutions like the World Bank in 1946 to manage global financial imbalances.

But how does PNG fit into this? PNG’s use of US Dollars in trade is linked to its historical ties with Australia, which was a signatory to the Bretton Woods Agreement. PNG’s economic model was adapted from Australia’s, embedding it into a system reliant on US Dollars for international transactions. As a resource-exporting nation, PNG benefits from using a globally recognised and stable currency like the US Dollar for its trade in commodities such as Liquefied Natural Gas (LNG), gold, and coffee.

As for why the US Dollar was chosen as the global reserve currency, it was due to the United States emerging from World War II with a robust economy, its military dominance instilling confidence in its stability, and its democratic governance reinforcing trust in its financial policies, making it a reliable foundation for global trade and economic systems.

Over time, other currencies like Germany’s Deutschmark, Japan’s Yen, and later the Euro have challenged the dominance of the US Dollar. More recently, emerging economies such as China have sought to reduce their reliance on the Dollar through initiatives like de-dollarisation and promoting alternative currencies like the Chinese yuan. The BRICS bloc (Brazil, Russia, India, China, and South Africa) and newer members like Ethiopia and Egypt have also worked toward diversifying global financial systems.

Despite these challenges, analysts have noted that the US Dollar has remained stable over decades due to its widespread acceptance in international markets. PNG trades in US Dollars because it is part of a global financial system that relies on this currency for stability and convenience. The historical establishment of the Bretton Woods System and PNG’s economic ties with Australia have cemented this practice. 

While the US Dollar remains central to global trade and PNG’s economic transactions, could Papua New Guinea explore alternative currencies to enhance its trade and economic resilience in a changing global financial system?
