The Iran War: When the Hegemon Sets Oil on Fire to Save the Dollar

Eight days. That’s how long between the Supreme Court stripping the president’s tariff authority and the first missiles hitting Iran.

On February 20, the Court ruled 6-3 that IEEPA doesn’t grant tariff powers. $160 billion in collected revenue, $1.4 trillion in projected revenue over the next decade—gone. On February 28, the bombs fell. A week to move from fiscal weapon to kinetic one.

This isn’t about Iran’s nuclear program. It’s about what happens when a hegemon loses one tool and reaches for another. And what that tool is: control of the Strait of Hormuz, where 20 percent of global oil moves. Twenty million barrels a day. One weapon dies; energy becomes the mechanism.

Hormuz: The Energy Valve

The Strait of Hormuz is 33 kilometers wide. It’s the world’s narrowest chokepoint for oil. One-third of all seaborne oil passes through it—roughly 21 million barrels per day.

On March 2, the Iranian navy began mining the strait and deploying drone swarms. Within two weeks, 21 ships were attacked or detained. Tanker traffic dropped 70 percent, then to zero. Two thousand ships stranded. Twenty thousand sailors waiting.

Oil prices moved faster than in any previous conflict. Brent went from $80 in January to $126 by mid-March. Combined production from Kuwait, Iraq, Saudi Arabia, and the UAE fell by 10 million barrels per day—the largest energy disruption since 1973.

Europe was hit twice. Winter 2025–2026 was cold. Gas storage stood at 30 percent. Dutch TTF prices doubled to above €60/MWh. The ECB canceled its planned rate cut, raised inflation forecasts, and slashed GDP growth. The energy shock did what diplomacy couldn’t: forced Europe back into complete dependence on U.S. LNG, American shale, and dollar-denominated settlement.

Why This Had to Happen

The U.S. has a fiscal problem. Debt interest payments in 2026 exceeded the defense budget for the first time: $1.05 trillion. Total debt approaches $40 trillion. The deficit runs at $1.9–2.1 trillion per year—nearly 6 percent of GDP.

Tariffs were supposed to be a solution. Not just trade leverage, but fiscal mechanism. The plan: $1.4 trillion over a decade. Then the Supreme Court killed it. IEEPA, the Court ruled, contains no tariff authority. No president had claimed this power before.

Trump responded within hours. Section 122: 15 percent global tariffs. March 11: new Section 301 investigations against 16 countries. If one weapon fails, activate another. But tariffs have limits. Energy has no limits.

The De-Dollarization Problem

The petrodollar system ended in 2023 when Saudi Arabia didn’t renew its dollar peg. BRICS nations are already settling in local currencies. China and Russia conduct most trade in yuan and rubles. De-dollarization progress stands at 72 percent on composite indices.

The yuan accounts for only 2 percent of global reserves. The dollar holds 57. But the direction is clear and accelerating.

Hormuz changes the calculus. When 10 million barrels disappear from the market, the currency of oil transactions becomes critical again. The dollar strengthens: DXY rose from 96 to 101. Countries that need oil need dollars or dollar infrastructure. Alternative systems—yuan settlement, BRICS mechanisms—aren’t enough when the market panics and liquidity is needed now. Energy crisis forces the world back to the dollar not through choice, but through physics.

The Fed Trap

The Federal Reserve left rates at 3.5–3.75 percent on March 18. Market expectations for 2026 were several cuts. Now: maybe one.

Powell acknowledged inflation isn’t retreating. PCE forecast raised to 2.7 percent. The Iran conflict is the driver.

This is the classic trap: economy needs lower rates, inflation won’t allow cuts. The oil shock adds supply-side pressure on top of already-elevated demand-side inflation. Stagflation shadow.

The Fed halted quantitative tightening and launched Reserve Management Purchases—$40 billion per month in Treasury bills. Not QE yet, but a liquidity signal. Fiscal dominance is asserting itself. Michael Howell’s 65-month liquidity cycle suggests global liquidity should grow through H2 2026. If the Fed cuts sooner due to recession or crisis, the cycle accelerates.

Asset Markets: What They’re Saying

Gold reached nearly $5,600. Central banks plan to purchase 850 tonnes in 2026, double pre-2022 levels. JPMorgan expects $5,055 by Q4. Goldman projects $5,400. JPM’s tail case: $6,300. Gold is saying one thing: central banks don’t trust the system.

Bitcoin oscillates in the $67,000–72,000 range. Down roughly $20,000 over the past year. The market bounces off $72,000 repeatedly. Crypto isn’t functioning as safe haven; it’s responding to liquidity. When the wave arrives, BTC should be among the first beneficiaries. For now: waiting.

Equities live in two worlds. AI-linked tech shows strong flows. The rest feels the oil shock, rate uncertainty, and deteriorating consumer expectations.

The Hegemonic Map

The U.S. lost its tariff weapon. The dollar was weakening. De-dollarization was accelerating. BRICS was building alternatives. China and Russia were already trading around the dollar.

The Iran operation restored multiple levers: energy control, inflationary pressure on competitors, dollar strengthening through oil demand, and a demonstration that the hegemon still uses force over energy flows.

Was it planned? In hegemonic analysis, that’s the wrong question. The question is: who benefits and what structural effects follow. Answer: the United States. Every consequence strengthens the dollar short-term.

Long-term tells a different story. Every such action drives the world faster toward alternatives. China, India, and BRICS will emerge with greater motivation to build energy infrastructure independent of U.S. chokepoints. Hormuz is both the dollar’s medicine and its disease symptom.

What Matters Next

Hormuz reopening. As long as the strait is blocked, oil stays above $100 and the dollar stays strong. April closure means temporary shock. Extended closure means real stagflation.

Fed reaction. If Powell cuts rates due to recession while inflation stays high, that’s the moment the central bank surrenders to the budget.

BRICS summit in India. If the “Unit” currency concept gets concrete plan, it’s the largest de-dollarization step since the petrodollar ended.

Gold and BTC. Gold above $4,500 and BTC breaking $72,000 signal the liquidity wave has begun.

What Would Break This Analysis

If the Iran operation was purely security—no macro intent, no energy logic, the hegemonic angle weakens. If Hormuz reopened within weeks and oil returned below $80, the leverage would be minimal. If BRICS ended without concrete currency plans, the de-dollarization threat would be overstated. If the Fed cut rates while inflation fell, fiscal dominance would be questioned.

So far, signals point the other way.
