Oil Set for Fresh Surge as U.S.–Iran Threats Raise Fears of Hormuz Shutdown and Wider Economic Fallout

Oil markets head into the new trading week on edge after a sharp escalation in rhetoric between Washington and Tehran, with traders now forced to price in the possibility of a direct disruption to flows through the Strait of Hormuz.

Crude has already staged a rapid climb, moving from about $70 a barrel to above $100 since late February, when U.S. and Israeli strikes on Iran marked the start of the current conflict. The latest exchange of threats over the weekend has shifted the conversation from risk to probability.

Donald Trump raised the stakes on Saturday, warning that the United States could begin targeting Iran’s power infrastructure if the Strait is not reopened within 48 hours, saying strikes would start with the “biggest” facilities.

Tehran responded with threats to target oil facilities in the region.

“If Iran’s fuel and energy infrastructure is attacked by the enemy, all infrastructure of energy, information technology, and desalination facilities belonging to the US and the (Zionist) regime in the region will be targeted,” said Ebrahim Zolfaqari.

Iran’s Revolutionary Guards went further on Sunday in a separate statement, signaling that a full closure of the Strait would follow any U.S. strike, while warning that companies tied to the United States could be “completely destroyed” and that energy installations in countries hosting U.S. forces would be considered legitimate targets.

That language matters for markets, as the Strait of Hormuz is not simply another shipping lane. Roughly a fifth of the world’s oil supply moves through the narrow corridor, along with a large share of global liquefied natural gas. There are few viable alternatives at scale, and even partial disruption tends to send freight rates, insurance premiums, and crude prices sharply higher.

In the early phase of the conflict, Iran appeared to be calibrating its response, targeting selected vessels while avoiding a complete shutdown. The latest threats suggest that restraint may be conditional, tied directly to whether U.S. strikes materialize.

For traders, that introduces a different kind of risk. The market is no longer reacting to actual supply losses alone but to the growing chance of a sudden, politically driven shock. That shift typically shows up first in volatility and in the widening gap between prompt prices and longer-dated contracts, as buyers scramble to secure near-term supply.

The knock-on effects are already visible globally. In the U.S., gasoline prices are approaching $4 per gallon, a level that tends to have both economic and political consequences. Higher fuel costs feed quickly into transportation and production expenses, pushing up the price of goods across the economy.

That dynamic complicates the outlook for the Federal Reserve. Energy-driven inflation is among the hardest to offset, particularly when it is tied to external shocks rather than domestic demand. Expectations for interest rate cuts have already been pushed further out, and a sustained period of elevated oil prices would reinforce that shift.

There is also a broader policy tension at play. The administration has prioritized fossil fuel output while rolling back several clean energy measures introduced previously. Yet the current surge in demand, driven in part by the rapid buildout of data centers and industrial capacity, is colliding with the limits of existing supply infrastructure.

Energy analysts note that geopolitical shocks of this nature tend to expose structural imbalances. In this case, years of underinvestment in spare production capacity and the continued reliance on key transit routes like Hormuz have left the market vulnerable to exactly this kind of disruption.

Beyond oil, the conflict is beginning to ripple through other supply chains. The Gulf region is a conduit not only for energy but also for chemicals, fertilizers, and specialized gases such as helium. Any sustained disruption could tighten supply in sectors that are already sensitive to price swings.

What distinguishes the current situation from previous flare-ups is the convergence of pressures. Oil markets are dealing simultaneously with geopolitical risk, rising demand linked to AI and industrial expansion, and policy uncertainty in major consuming economies.

However, the key variable currently remains the Strait. A full closure would represent a severe escalation, likely forcing coordinated responses from major economies, including emergency stockpile releases and naval efforts to secure shipping lanes. Even short of that, the threat alone is enough to keep a risk premium embedded in prices.

Markets are expected to open with that reality in focus.
