Disclaimer: This commentary reflects publicly available information as of 5 March 2026. Given the fast-moving nature of the conflict and markets, figures and conditions may change rapidly. The analysis is intended to offer an indicative overview rather than precise forecasts.
As of 5 March 2026, the sixth day of the US–Israeli military campaign against Iran, the conflict has expanded beyond its regional origins. What began as strikes and retaliation is now behaving like a global economic shock. Iranian drone attacks on tankers, missile launches, and threats to international shipping have pushed a critical maritime corridor into paralysis. Marine traffic data shows tanker transits through the Strait of Hormuz have dropped from typical daily volumes to near zero, with hundreds of vessels waiting outside the Gulf. Several ships have reportedly been damaged and casualties have been recorded. Importantly, major insurers, including those operating through the Lloyd’s market, have either cancelled or dramatically increased war-risk coverage. Even without a neat, formal naval blockade, commercial passage becomes practically impossible when insurance is withdrawn and risk premiums become unpayable.
This is the subtle mechanism by which a war transforms into an economic shock. It is not only missiles that close shipping lanes, but contracts, underwriting decisions, and the pricing of risk.
The deeper issue is structural. Globalisation made the world efficient by routing energy, fertiliser, manufactured goods, and finance through narrow corridors. Those corridors are also vulnerabilities. Iran’s retaliation strategy resembles economic warfare because it targets chokepoints, exploiting global dependence without needing to defeat American military power in direct confrontation.
For the United States, the spillover is already tangible: higher energy costs, renewed inflation anxiety, financial volatility, and strained alliances. America is more resilient than it was during older oil shocks because it now produces significant domestic energy. Yet resilience is not immunity. In a globally priced market, disruption thousands of miles away still lands on the American consumer’s doorstep.
The Strait of Hormuz remains the world’s most critical oil transit point. Approximately 20 million barrels of oil pass through it each day, about one fifth of global consumption, alongside significant LNG volumes. When that flow is interrupted or made uninsurable, markets do not wait politely for confirmation. They price the risk immediately.
That is why oil prices have climbed. Brent crude has traded in the low-to-mid $80s, with volatile sessions pushing higher intraday, while WTI has risen into the high $70s. For American households, the more visceral indicator is petrol. On 5 March, reported national average gasoline prices vary slightly by source and region, but sit broadly in the $3.11–$3.25 range, reflecting a sharp week-on-week increase. Moves of 10 cents or more in a single day matter because they do not stay contained at the forecourt. They feed transport costs, airline pricing, food distribution, and consumer sentiment. Forecasts of $4.00-plus per gallon if disruption persists are plausible, not as certainty, but as a reflection of how quickly energy shocks compound when a key corridor remains impaired.
Even as a net exporter, the United States still absorbs global pricing. Domestic producers do not sell oil to Americans at a discount simply because it is produced at home. Refineries, transport, and petrochemicals remain benchmarked to global markets. Higher energy therefore behaves like a broad tax on the entire economy, inflating freight, packaging, aviation, manufacturing inputs, and ultimately retail prices.
Energy shocks rarely remain energy shocks. Oil and gas costs feed fertiliser prices because fertiliser production is energy-intensive and often gas-linked. Higher fertiliser costs raise farming costs, and farming costs eventually become grocery bills. At the same time, global grain trade is exposed to adjacent chokepoints, particularly Bab el-Mandeb, through which large quantities of trade and commodities pass. When shipping is disrupted and fuel rises, the world’s food system becomes more expensive almost by definition.
This is why commentators describe the current moment as a potential third major price surge since the pandemic, after the original COVID-era supply shock and the inflation wave that followed the Ukraine conflict. Americans may not feel it as geopolitics. They will feel it as a blunt sentence: everything costs more again.
At that point, the Federal Reserve is dragged back into a familiar dilemma. If energy-driven inflation re-anchors, the Fed may be forced to keep rates higher for longer, slowing growth and raising borrowing costs across mortgages, credit cards, and business lending. If it holds back to protect growth, inflation risks becoming sticky. Either option is politically damaging and economically destabilising in its own way.
Markets are already responding. Fuel-dependent sectors such as airlines tend to weaken, energy firms strengthen, and broader indices wobble as investors reprice risk. The dollar typically benefits at first because in times of fear the world still runs toward dollar liquidity and US Treasuries. That short-term strength, however, carries a longer-term question beneath it. The dollar’s energy dominance has never been a single document that can be torn up overnight. It is a system held together by market depth, legal architecture, and habit. But wars like this create incentives to diversify payment channels and settlement routes. Not because alternatives are suddenly superior, but because dependence becomes frightening.
That is how structural change begins. Not with a dramatic collapse, but with repeated reasons to hedge.
The Gulf region adds another layer of financial exposure. Sovereign wealth funds in the region manage vast portfolios across US equities, Treasuries, and American technology. If Gulf states face emergency spending demands from war, reconstruction, or domestic stabilisation, capital flows could change rapidly. Asset sales are not guaranteed, but the possibility adds to volatility. Volatility matters because it hits pensions, retirement accounts, business confidence, and consumer behaviour, all at once.
Then there is the alliance question, which the war has thrown into sharp relief. Britain has avoided participation in offensive strikes, limiting its posture to defensive measures and stressing the lessons of earlier interventions. Several European states have been cautious, wary of escalation and energy blowback, while NATO as an institution remains defensive because its collective obligations are not designed to underwrite offensive campaigns. This is not simply timidity. It is a recognition that European economies, having endured recent energy shocks, cannot easily absorb another prolonged crisis.
The U.S. administration’s posture has been to project certainty and to pressure allies, including threats of trade consequences for reluctance. Yet coercion does not substitute for logistics. Washington can pledge naval escorts and risk insurance, but those measures take time to scale. President Trump’s reported promise of U.S.-backed political risk insurance and escorted convoys may prove meaningful, but not immediately. In a crisis where insurance cancellation can freeze shipping overnight, time becomes the enemy. The bluff is not that the United States lacks power. The bluff is the suggestion that power can instantly restore market calm.
Finally, there is the fiscal reality. Wars cost money directly through operations and indirectly through higher debt servicing if rates remain elevated. The longer the conflict persists, the more it drags domestic budgets into the war’s gravitational field. Estimates for prolonged disruption range widely, but the direction is clear: long wars become economic drains, especially when the economy is already sensitive to inflation and borrowing costs.
How long can this last without serious economic damage? Duration matters more than headlines. Some analysts believe escalation pressure makes an extended conflict hard to sustain politically, suggesting the most intense phase may not last beyond weeks. Others warn that if Hormuz disruption persists for weeks rather than days, recession risks rise sharply, and if it persists for months, the combined pressure of energy inflation, food inflation, market volatility, and alliance fractures becomes more than a temporary disturbance. It becomes a stress test of the global order, and of America’s ability to guarantee the stability on which its economic leadership rests.
The United States can outspend adversaries and outfight them in conventional terms. What it cannot do is repeal geography or command insurers, shippers, and markets to behave as if risk does not exist. The Strait of Hormuz is not simply a narrow waterway. It is a mirror reflecting how the efficiencies of globalisation have become vulnerabilities, and how power in the modern world is measured not only by what you can destroy, but by what you can keep open.
