Oil Prices Hit Highest Levels Since 2023 as Iran War Disrupts Strait of Hormuz Shipping

Crude oil has not been this expensive in three years, and the reason is straightforward: the world's most critical energy chokepoint is effectively closed. The US-Israel military campaign against Iran has disrupted shipping through the Strait of Hormuz — the narrow passage through which roughly a fifth of the world's oil supply normally flows — and energy markets have responded exactly as they always do when that particular geography becomes dangerous. Prices spiked, traders repriced risk, and the consequences are rippling outward through every part of the global economy that runs on energy, which is to say every part of the global economy. Wall Street just posted its worst week since October, and that is only the beginning of what elevated oil prices tend to do to financial markets when they persist.

How the Strait of Hormuz Became the Price Setter

The Strait of Hormuz is seventeen miles wide at its narrowest navigable point. Through those seventeen miles, tankers carry crude oil and liquefied natural gas from Saudi Arabia, Iraq, Kuwait, the UAE, Qatar, and — until recently — Iran itself. On a normal day, approximately 20 million barrels of oil pass through the strait. That is equivalent to roughly 20% of global daily petroleum consumption moving through a channel narrow enough that the tankers transiting it can see both shores simultaneously.

When that passage becomes a war zone, tanker operators face an immediate calculation: the war-risk insurance premium to transit goes from a manageable line item to a potential deal-breaker, and the underlying physical risk of a vessel being struck by a missile, mine, or drone becomes a real operational concern rather than a theoretical one. Most major tanker operators have already suspended Hormuz transits or are demanding extraordinary premiums from cargo owners to maintain them. The practical effect is that a significant portion of Gulf crude is either stranded or being rerouted on paths that add weeks to delivery times and hundreds of thousands of dollars to each voyage.

What Triple-Digit Oil Does to Inflation

Oil above a hundred dollars a barrel is not just an energy problem. It is a generalized cost-of-living problem that touches almost every category of consumer spending. Gasoline prices follow crude with a lag of a few weeks, and American drivers filling their tanks are already seeing the early stages of that pass-through. Airline ticket prices are set to climb as jet fuel costs surge — carriers had been benefiting from relatively stable fuel prices for the better part of 2025, and those hedges are now running off against a much higher spot price. Trucking costs are rising, which means the cost of moving everything from produce to manufactured goods increases. Heating oil and natural gas prices, especially relevant for the Northeast and Midwest, are adding to household budget pressure.

Central banks were already navigating a delicate position before the oil shock. The Federal Reserve had been signaling a gradual path toward easier monetary policy on the assumption that inflation was continuing to moderate. That assumption is now under serious question. Oil-driven inflation is particularly difficult for central banks to address because it originates from a supply shock outside their control rather than from excess domestic demand that rate hikes can cool. Raising interest rates to fight oil price inflation risks choking off economic activity without actually addressing the supply constraint driving prices higher.

Wall Street's Worst Week Since October

Financial markets have been absorbing multiple simultaneous shocks, and the past week encapsulated all of them at once. The February jobs report showed a net loss of 92,000 positions — a catastrophic miss against forecasts. Oil crossed a hundred dollars a barrel. The dollar strengthened against most currencies as investors sought safety, putting pressure on emerging market economies that borrow in dollars and buy energy in dollars. Equity markets repriced growth expectations downward as analysts revised their corporate earnings forecasts to account for higher input costs, tighter consumer spending, and the possibility that the Fed is now trapped between fighting inflation and supporting employment.

The sectors that typically suffer most in an oil price spike environment — airlines, consumer discretionary, retail, and transportation-heavy industrials — led the equity market lower. Energy stocks were the rare beneficiary, as they almost always are when crude prices surge, but the broader index performance reflected a market that is genuinely uncertain about how to price assets in an economy facing the stagflationary combination of slowing growth and rising energy costs.

The Strategic Petroleum Reserve Question

The United States maintains the Strategic Petroleum Reserve as exactly the kind of buffer intended for supply disruptions of this nature. The Biden administration drew down the SPR significantly in 2022 during the Russia-Ukraine conflict and subsequent price spike, and the reserve's current level has been a subject of ongoing debate about whether it was rebuilt sufficiently before the next crisis arrived. The Trump administration now faces pressure to authorize an SPR release to take some edge off domestic gasoline prices, but the calculus is complicated: releasing reserves signals confidence that the disruption is temporary, but it also depletes a strategic asset that may be needed if the conflict escalates further or persists longer than current assessments project.

The IEA has convened emergency consultations among member states about a coordinated strategic reserve release, which is the standard international mechanism for addressing major supply disruptions. Coordinated releases have historically been most effective when the disruption is clearly defined and finite in duration. The current situation — an active military conflict with an uncertain resolution timeline — is harder to model against reserve release volumes than the typical supply outage scenarios the system was designed to address. Markets are watching the IEA deliberations closely, but the consensus view among energy traders is that reserve releases alone are unlikely to push prices back below the hundred-dollar threshold as long as Hormuz remains effectively closed.
