The conventional wisdom holds that American military entanglements in the Middle East accelerate the decline of dollar hegemony. One prominent economist is making the opposite case.

In a Wall Street Journal editorial that has sparked debate across financial circles, Diana Choyleva contends that U.S. military engagement in Iran is actively defending the petrodollar system rather than hastening its demise. Her argument centers on a blunt geopolitical calculus: whoever controls the flow of oil controls the currency in which it trades.

The petrodollar arrangement, now 75 years old, rests on a straightforward premise. Oil is priced and traded globally in U.S. dollars, which in turn sustains dollar dominance across international commerce. That system has faced mounting pressure in recent years as China has expanded yuan-based settlement mechanisms and deepened economic ties with Arab nations traditionally aligned with Washington.

Testing the Security Bargain

Choyleva's central thesis challenges analysts who view the Iran conflict as a "perfect storm" eroding American financial influence. She argues instead that military action has reinforced the foundational bargain underpinning the petrodollar: security guarantees in exchange for dollar-denominated oil pricing.

According to her analysis, most Arab nations have backed the U.S. campaign against Iran. Critically, she writes, "the security commitment was tested; it held." That demonstration of American willingness to deploy force in defense of Gulf allies has validated the security-for-pricing arrangement that keeps oil markets anchored to the dollar.

The logic extends beyond Iran. Choyleva points to recent developments in Venezuela, where the removal of President Nicolás Maduro has positioned the United States to exert influence over Venezuelan oil reserves. Combined control over Western Hemisphere production would give Washington command of oil volumes exceeding OPEC's collective output—providing substantial leverage to maintain dollar pricing.

Two Paths to Energy Dominance

Choyleva sketches two potential endgames for the Iran conflict, both of which she believes would strengthen dollar-based oil trade.

The first scenario involves a negotiated settlement granting the United States influence over Iranian oil flows. The second, more aggressive outcome would see American forces seize Kharg Island and establish control over the Strait of Hormuz—the chokepoint through which roughly one-fifth of global oil supplies pass.

Either resolution, in her view, would expand the share of oil transactions conducted in dollars rather than contract it. The strategic objective is not merely military but monetary: ensuring that energy markets remain denominated in the currency Washington prints.

Pushback Against De-Dollarization Narratives

The analysis directly contradicts a growing chorus of voices predicting the petrodollar's imminent collapse. Critics of U.S. foreign policy have long argued that military overreach undermines the dollar's reserve status by driving rival powers to seek alternatives. China's promotion of yuan-based oil futures and bilateral trade agreements outside the dollar system seemed to validate those concerns.

Choyleva dismisses such interpretations as misreading the strategic landscape. "Those who conclude that the petrodollar is already in its death throes are reading the map upside down," she writes. "The storm is real. The dollar is fighting back."

Her framing recasts American military action not as reckless adventurism but as calculated defense of the financial architecture that has sustained U.S. economic primacy since the Bretton Woods era. Control of energy infrastructure, in this view, translates directly into monetary influence.

Questions of Sustainability

The argument raises thorny questions about the long-term viability of maintaining dollar dominance through military means. Securing oil flows requires sustained defense commitments, forward-deployed forces, and periodic demonstrations of resolve—all of which carry fiscal and political costs.

Whether Gulf allies will continue to accept this bargain as China offers economic partnerships without security strings remains an open question. Beijing's Belt and Road infrastructure investments and energy purchase agreements provide an alternative model that does not require hosting American military installations or denominating trade in foreign currency.

The Venezuelan situation also presents complications. While Washington may have removed Maduro, translating regime change into durable control over oil policy in a country with deep anti-American sentiment and crumbling infrastructure is far from assured.

The Broader Debate

Choyleva's thesis has energized debate among economists and foreign policy analysts about the relationship between military power and monetary systems. Traditional realists have long understood that reserve currency status rests partly on security guarantees. What remains contested is whether that model can persist as global power diffuses and the costs of enforcement mount.

The petrodollar system emerged from a specific historical moment when American economic and military dominance was unquestioned. Maintaining it in an era of multipolarity may require not just defending oil infrastructure but adapting to a world where energy markets are more fragmented and currency competition more intense.

For now, Choyleva's analysis offers a counternarrative to declinist predictions. Whether the dollar is genuinely "fighting back" or merely delaying an inevitable transition will likely depend on factors beyond military control—including fiscal discipline, economic competitiveness, and the willingness of other nations to continue financing American deficits.

The Iran conflict may indeed be testing the petrodollar system. What that test ultimately reveals about the durability of dollar dominance remains to be seen.
