How Oil Keeps the Dollar Strong
The 'petrodollar' refers to U.S. dollars earned by oil-exporting countries selling their oil. Most international oil sales happen in dollars, creating massive global demand for the U.S. currency. These oil-rich nations often then deposit or invest those dollars, frequently within the United States. This continuous cycle helps keep the U.S. dollar strong and central to global trade, making it the world's most important currency for many transactions.
