Prof. Dr. Haider Ali Al-Dulaimi College of Administrative Sciences – Al-Mustaqbal University The relationship between oil and the U.S. dollar was not merely the result of a temporary commercial arrangement; rather, it represented one of the major developments that contributed to shaping the modern global financial system. Since the 1970s, the pricing and trading of oil in U.S. dollars has become increasingly established, coinciding with the expansion of financial and strategic relations between the United States and major oil-producing countries, particularly Saudi Arabia. This arrangement contributed to generating substantial global demand for the dollar, as oil-importing countries needed to hold U.S. currency to finance their energy purchases. Oil-exporting countries, meanwhile, accumulated significant financial surpluses, part of which was often reinvested in global markets and financial assets, including U.S. assets. The Dollar: From a U.S. Currency to a Global Currency One of the most significant effects associated with the petrodollar system has been the strengthening of the dollar’s position as a major currency in international trade and global reserves. As the volume of dollar-denominated oil trade expanded, global demand for the U.S. currency increased, contributing to the depth and liquidity of American financial markets. For the United States, this position provided an important financial advantage. The U.S. government, corporations, and financial institutions have been able to borrow and invest globally using a currency that enjoys broad international demand. The United States has also benefited from the flow of part of the financial surpluses generated by oil exports into dollar-denominated markets and assets. Oil-producing countries, in turn, received substantial revenues that enabled them to finance infrastructure and development projects, establish sovereign wealth funds and overseas investments, and accumulate significant financial reserves. The Other Side of the System The strength that the dollar has brought to the global financial system has simultaneously created a degree of dependence on U.S. monetary policy. When the Federal Reserve raises interest rates, the cost of dollar-denominated financing may increase for governments and companies in other economies, even when the reasons behind such decisions are primarily related to conditions within the U.S. economy. The extensive reliance of international trade on the dollar also provides the United States with considerable financial and geopolitical influence. This becomes particularly evident when financial sanctions and restrictions on access to the international financial system are employed as instruments of foreign policy. This is where the concept of seigniorage becomes relevant: the issuer of an international currency can benefit from its ability to issue that currency at a relatively low cost while using it to acquire goods, services, and assets from abroad. This represents a significant economic advantage, but it also reflects an imbalance in the distribution of power within the international monetary system. Is the Petrodollar Responsible for the Resource Curse? The petrodollar system alone cannot be held responsible for what is commonly known as the “resource curse.” Nevertheless, large inflows of oil revenues can reinforce rentier economic structures if they are not accompanied by effective policies aimed at diversifying production, developing industry, and increasing domestic productivity. This is where the central paradox emerges: oil wealth can provide a country with enormous financial capacity, yet it does not necessarily guarantee the development of a diversified and sustainable economy. An economy that depends excessively on the export of a single resource remains vulnerable to fluctuations in global prices, changes in demand, and transformations in energy markets, regardless of the size of its financial reserves. Iraq and the Most Important Lesson For Iraq, the issue is not merely the currency in which oil is priced, but rather how oil revenues are managed and transformed from financial inflows into productive capital. Possessing substantial oil resources is not sufficient if the economy remains heavily dependent on oil to finance the public budget, imports, and government expenditure while the private sector and domestic production remain relatively limited. The real challenge lies in building an economy capable of using oil revenues to finance education, infrastructure, industry, agriculture, technology, and private-sector development so that oil can be transformed from a permanent source of dependence into an instrument for financing the transition toward a more diversified economy. Conclusion The petrodollar was not merely an arrangement for selling oil in U.S. dollars. It became part of a much broader system connecting energy, currency, financial markets, and geopolitical power. Both the United States and oil-producing countries have benefited from this system in different ways. At the same time, however, it has created varying degrees of mutual dependence and economic and financial risk. Therefore, the most important economic question today is not simply Will oil continue to be priced in U.S. dollars? Rather, the broader question is Can oil-producing countries, particularly Iraq, use their oil revenues to build economies that will not remain dependent on oil indefinitely? Ultimately, the challenge lies neither in the dollar alone nor in oil alone, but in how the financial power generated by oil is managed and transformed into sustainable economic development.
