1st March 2026
The outbreak of open conflict between the United States and Iran has triggered one of the most dramatic shocks to global energy markets in years.
Oil prices were already rising on geopolitical tension, but the escalation into direct military confrontation and Iran's reported closure of the Strait of Hormuz—has transformed a regional dispute into a global economic threat.
The world now faces a moment of profound uncertainty, with oil markets absorbing not only the immediate disruption but also the possibility of a prolonged crisis that could reshape global trade, energy security, and economic stability.
A Market on Edge: How Oil Prices Are Reacting
Oil prices have surged sharply as traders price in what analysts describe as a "war premium." Even before markets reopened, experts warned that crude could jump $5-$7 per barrel immediately, with the potential for far more extreme spikes if shipping lanes remain unsafe. Brent crude had already climbed in the days leading up to the strikes, reflecting roughly $8–$10 per barrel of Iran‑related risk embedded in prices.
The attack on Iran by the US and Israel has intensified these pressures. Analysts warn that the market has long underestimated the vulnerability of Middle Eastern supply routes. One former White House energy advisor noted that traders are only now beginning to grasp the scale of the threat, predicting that prices could break above $100 per barrel if Iran makes the Strait of Hormuz impassable.
The Strait of Hormuz: The World’s Most Dangerous Chokepoint
At the centre of the crisis lies the Strait of Hormuz, a narrow waterway between Iran and Oman that handles a staggering share of global energy flows. It is not merely important—it is indispensable.
Around a quarter of all seaborne oil passes through the strait.
One‑fifth of global LNG shipments, almost all from Qatar, rely on this route.
In 2025, more than 14 million barrels per day of crude moved through Hormuz—about one‑third of global seaborne exports.
Roughly 20 million barrels per day transited the strait in 2024, underscoring its long‑term strategic importance.
Iran’s reported decision to shut down the strait following US–Israeli strikes has already forced oil majors, tanker operators, and LNG carriers to halt or divert shipments. Satellite data shows vessels clustering near UAE ports, unwilling to risk transit after receiving radio warnings from Iran’s Revolutionary Guards that “no ship is allowed to pass.”
The UK Navy has countered that Iran’s orders are not legally binding, but even this reassurance has not restored confidence. Greece, among others, has advised its shipping fleets to avoid the entire region.
Why This Crisis Is So Dangerous
A prolonged closure could trigger a global recession
Energy analysts warn that a sustained shutdown of Hormuz would be catastrophic. With a third of seaborne crude and a fifth of LNG at risk, the world could face a supply shock severe enough to push the global economy into recession.
There are few viable alternatives
Saudi Arabia and the UAE can bypass the strait via pipelines, but together they can reroute only around 3 million barrels per day—a fraction of the 15–20 million that normally pass through Hormuz.
LNG markets are even more exposed
Qatar, the world’s second‑largest LNG exporter, has no alternative route. Even short‑term disruptions could spark bidding wars for available cargoes, driving up energy prices in Asia and Europe.
Iran has the tools to sustain disruption
Iran possesses extensive stockpiles of naval mines, fast‑attack boats, submarines, and short‑range missiles, giving it the ability to make the strait unsafe even without formally closing it.
Tanker behaviour shows the market’s fear
At least 14 LNG tankers have already slowed, turned back, or stopped near the strait—an early sign of a broader freeze in maritime traffic.
The Broader Geopolitical Picture
The conflict has drawn in global powers. China, heavily dependent on Gulf energy, has urged de‑escalation, warning that instability threatens the “common interests of the international community.”
Meanwhile, the US has expanded its naval presence, and Iran has used military drills to demonstrate its ability to control or disrupt the waterway. The situation remains fluid, with diplomatic efforts in Geneva offering a narrow path to de‑escalation—but also the risk of collapse. A failed negotiation could unleash further military escalation and a rapid surge in oil prices.
What Happens Next? Three Possible Scenarios
Diplomatic Breakthrough (Best Case)
A negotiated framework could unwind the risk premium, pushing Brent back toward the $60 range as markets stabilise. OPEC+ would likely face pressure to cut production to prevent oversupply.
Prolonged Standoff (Middle Case)
Even without full closure, intermittent attacks, naval warnings, and insurance spikes could keep prices elevated in the $80–$90 range. LNG markets would remain tight, and Asian economies would feel the strain.
Full Escalation (Worst Case)
A sustained shutdown of Hormuz would be unprecedented. Oil could surge well above $100, global shipping would seize up, and recession risks would become immediate.
A Crisis Still Unfolding
The war between the US and Iran has exposed the fragility of the global energy system. The Strait of Hormuz—long recognised as the world’s most critical chokepoint—has become the focal point of a crisis that threatens not only oil markets but the broader global economy. With tankers halted, LNG carriers turning back, and military forces mobilising on both sides, the world is entering a period of profound uncertainty.
The next days and weeks will determine whether this crisis stabilises or spirals into a historic disruption. For now, the only certainty is that the global energy landscape has changed—and the consequences will be felt far beyond the Gulf.
