Why the price of oil can dictate the strength of a nation's currency
In short: The term petrocurrency is often misunderstood, carrying three distinct meanings ranging from oil-export revenues to the global dominance of the US dollar. While some nations see their currency value rise alongside oil prices, this link can trigger economic instability, a phenomenon known as Dutch disease that hampers industrial competitiveness.
At its core, petrocurrency refers to the currencies of oil-producing nations that tend to appreciate when oil prices climb and depreciate when they fall. Historically, the Dutch guilder was a prime example; during the 1970s, as OPEC price hikes surged, the guilder strengthened significantly. This caused the Dutch economy to suffer from Dutch disease, where the high value of the currency crowded out domestic manufacturing and services, making exports non-competitive on the global market.
The relationship between oil and currency is not always consistent. The Canadian dollar is frequently debated as a petrocurrency, yet recent years have shown a disconnect. Despite the global energy crisis of 2021–2022, the Canadian dollar remained relatively static. Experts speculate this shift stems from the rise of ESG-focused investing, the growth of the US petroleum industry, and a general weakening of investor interest in Canadian oil sands. Similarly, while the US dollar has long been the dominant unit for pricing oil—a status solidified by 1970s agreements with Saudi Arabia—nations like Iran and Venezuela have sought to bypass this by allowing oil trades in euros or yuan.
The landscape of oil-backed finance continues to evolve through unconventional experiments. In 2018, Venezuela launched the petro, a cryptocurrency intended to circumvent US sanctions and support its struggling economy, though the project was ultimately liquidated in January 2024. Meanwhile, China has introduced a yuan-denominated futures market to encourage its own currency's use in oil trade. As the world transitions, the long-term relevance of these petro-linked financial structures remains uncertain, especially as production capacity expands and global reliance on traditional oil exports faces potential shifts.
