Opinion
For decades, Americans have been told that U.S. involvement in the Middle East is primarily about oil. That explanation is increasingly incomplete.
The United States is now one of the world’s largest oil producers. Yet Washington remains deeply invested in the security of the Persian Gulf, the stability of major energy exporters and the financial architecture surrounding global commodity trade. The reason is that the Middle East sits at the center of something larger than the physical supply of petroleum: the dollar-based international economic system.
This does not mean every war, alliance or military deployment in the region is secretly engineered by central bankers. Middle Eastern conflicts have their own territorial, religious, national and security causes, and oil supplies and prices still matter enormously. But beneath those visible interests lies another strategic concern: preserving a world in which governments, banks and companies conduct much of their business in dollars.
The short answer
The dollar’s international role gives the United States cheaper financing, unusually strong demand for its government debt and more room to respond to crises. It can also shift part of the inflationary burden of a strong dollar onto countries that buy goods or repay debts in dollars. That is a real privilege, even if slogans about “exporting inflation” often exaggerate what it can do.
Reserve-currency status does not make inflation disappear, and it does not give the Federal Reserve permission to create money without limit. It gives the United States a wider margin for error than most countries possess.
The dollar is America’s most valuable export
The dollar remains the dominant global reserve currency. According to the International Monetary Fund, it accounted for 56.92 percent of global foreign-exchange reserves in the third quarter of 2025, far ahead of the euro or China’s renminbi. The Federal Reserve’s 2025 review also found that the dollar remained dominant across reserves, international lending, trade invoicing and cross-border finance.
That creates persistent demand for dollar-denominated assets, especially Treasury securities. Foreign central banks need dollars to manage exchange rates and protect their economies during crises. International banks need them to settle transactions. Companies need them to purchase commodities, service debts and insure themselves against currency risk.
In practical terms, the United States can issue dollars and Treasury bonds in exchange for real goods, services and capital. Economists sometimes call this America’s “exorbitant privilege.” As the Federal Reserve has explained, dollar dominance can increase the credit available in the United States and lower borrowing costs for American households, businesses and the government.
How America exports part of its inflation
Reserve-currency status also gives the Federal Reserve more room to expand dollar liquidity during a crisis. When the Fed creates bank reserves and purchases securities, it increases the supply of dollars in the financial system. In a country whose currency has little international demand, aggressive monetary expansion can quickly trigger capital flight, a falling exchange rate and sharply higher import prices.
The United States faces those risks too. But global demand for dollars and Treasury securities can absorb part of the additional supply. Some liquidity flows into foreign reserves, international banking, trade settlement and dollar-denominated investments instead of immediately chasing American consumer goods.
A strong dollar adds another layer of protection. When the dollar appreciates, imported goods generally become cheaper for American buyers. At the same time, countries whose currencies weaken against it must pay more in local-currency terms for oil, food, machinery and other products priced in dollars. Their companies also face higher costs when servicing dollar-denominated debt.
The IMF estimated in 2022 that, on average, a 10 percent dollar appreciation passed through into roughly one percentage point of inflation abroad. Research summarized by the Federal Reserve Bank of New York likewise shows how dollar-centered trade and finance transmit U.S. monetary shocks across borders.
In that limited but meaningful sense, the United States can export part of its inflationary pressure. The phrase is useful only if we remember the limits. Excess demand can still raise prices at home. A strong dollar can hurt American exporters and manufacturers. Dollar appreciation can also strain foreign financial systems and eventually rebound on the United States.
Why the Middle East still matters
Oil remains the world economy’s most strategically important commodity, even when the United States imports less Middle Eastern petroleum than it once did. A disruption in the Strait of Hormuz can affect the global price Americans pay regardless of where their particular barrel was produced.
But the currency in which energy is priced, financed and insured matters too. Dollar-based commodity markets reinforce global demand for dollars. Energy exporters accumulate dollar revenue. That revenue moves through banks, investment funds and sovereign institutions, with some returning to dollar assets. This strengthens the network connecting energy trade, financial markets and American monetary power.
If a rival bloc moved a substantial share of energy trade, international borrowing and national reserves into another currency, the change would not destroy the dollar overnight. The dollar’s position rests on much more than oil: the scale of the U.S. economy, the depth of American capital markets, the liquidity of Treasury securities and confidence in American law are all essential.
But a sustained retreat could still raise federal borrowing costs, weaken the dollar, make imports more expensive, reduce the reach of sanctions and leave the Fed with less room to respond to recessions or financial crises without provoking a sharper currency or inflation response.
Protect the privilege by deserving it
Recognizing the value of dollar dominance does not make every challenge to it a justification for war. Military overreach, uncontrolled deficits and indiscriminate financial sanctions may encourage governments to search for alternatives.
The best defense of the dollar is institutional credibility: an independent Federal Reserve committed to price stability, a deep and predictable Treasury market, respect for contracts and property rights, sustainable public finances and sanctions used with restraint. American alliances and secure trade routes remain part of that defense, but military strength cannot preserve a monetary order if political instability and fiscal recklessness undermine confidence at home.
The dollar’s reserve status allows Americans to borrow more cheaply, import more affordably and confront crises with tools unavailable to almost any other nation. Losing that privilege would mean a lasting reduction in American living standards and power.
We should protect it not because the dollar entitles the United States to dominate the world, but because surrendering its advantages through complacency would be an extraordinary act of national self-harm.
