For much of this year, oil markets have oscillated between panic and relief. Every diplomatic headline has produced optimism. Every military escalation has restored anxiety. Every ceasefire has been followed by another exchange of missiles. The latest surge in crude prices is not simply another episode of volatility. It reflects a growing realisation that the conflict in the Middle East has entered a new phase. The question is no longer whether oil continues to flow. It is who controls the routes through which it flows. That distinction changes everything. Brent crude rebounded sharply after three consecutive sessions of heavy losses as fighting intensified once again across the region. Iran’s Islamic Revolutionary Guard Corps claimed to have launched ballistic missiles against a US air base and command centre in Jordan while also announcing attacks on three oil tankers. Washington confirmed that an Iranian attack had been intercepted, while the United States and Saudi Arabia conducted joint strikes against Iranian-backed groups operating in Iraq. This is no longer a conflict confined to Iran and Israel. Nor is it simply a confrontation between Tehran and Washington. It is becoming a regional struggle over the security of the world’s most important energy infrastructure.

Markets immediately understood the implications. Oil recovered despite the recent collapse that had erased almost 16% over three trading sessions, the sharpest decline since 2020. Investors were no longer reacting to inventories or demand forecasts. They were responding to the growing probability that the geopolitical risk premium had returned. The physical market tells the story more clearly than futures prices. Traffic through the Strait of Hormuz remains exceptionally limited. According to shipping data, only a handful of merchant vessels continue to transit one of the world’s most strategic maritime corridors. Iran has rejected proposals to share responsibility for the passage with Oman, insisting instead on maintaining direct control over the inbound shipping lane and part of the outbound channel. This is not merely a disagreement over maritime administration. It is a dispute over sovereignty. More importantly, it is a dispute over leverage.

For decades, the Strait of Hormuz has been the world’s most powerful energy chokepoint. Around one-fifth of global oil and liquefied natural gas exports normally pass through this narrow corridor linking the Persian Gulf to international markets. Every tanker that crosses Hormuz carries not only crude oil but also geopolitical significance. The current conflict demonstrates that control of energy no longer requires physically closing the strait. Uncertainty is sufficient. The market does not require a complete blockade to experience disruption. It only requires enough uncertainty for commercial operators to become more cautious. This is precisely the strategy that appears to be developing. Iran understands that permanently closing Hormuz would almost certainly provoke overwhelming military retaliation and severely damage its own economic interests. But maintaining ambiguity is considerably more effective. The objective is not necessarily to stop exports. It is to make exporting progressively more expensive. If transporting oil safely becomes significantly more expensive, the effective cost of energy rises regardless of production levels. This represents a structural shift in the functioning of commodity markets. For years, analysts concentrated on OPEC quotas, US shale production and Chinese demand. Today, shipping security has become equally important. This development is reinforced by the widening geographical scope of the conflict. The Red Sea remains unstable. Hormuz remains vulnerable. Saudi infrastructure continues to face threats from Iranian-backed groups. Russian refining capacity has already suffered repeated attacks linked to the war in Ukraine. Energy security is no longer concentrated in one theatre. It has become global. The consequence is a growing fragmentation of energy logistics. Companies increasingly seek alternative routes. Governments expand strategic petroleum reserves. Shipping firms demand higher compensation for political risk. Each adjustment appears rational when viewed individually. Collectively, they increase the structural cost of energy.

This is precisely why central banks find themselves in an increasingly uncomfortable position. Oil prices have once again become disconnected from domestic demand conditions. Price is driven by geopolitical risk. This creates a dilemma for monetary authorities. Higher interest rates cannot reopen shipping lanes. They cannot protect tankers. They cannot negotiate ceasefires. Nor can they reduce geopolitical risk. Yet they must respond to the inflation generated by those events. Inflation increasingly originates outside the economic system. It begins in geopolitics. Should they tighten policy in response to inflation they cannot directly influence? Or should they tolerate higher inflation in the hope that geopolitical shocks eventually subside? Neither option is attractive. Tightening risks slowing already fragile economies. Doing nothing risks allowing inflation expectations to become unanchored. The bond market has already begun to express its judgement. Long-term sovereign yields remain elevated despite signs of moderating economic growth. Investors increasingly demand compensation not only for inflation itself but also for the uncertainty surrounding its future path. Markets are pricing volatility. Not certainty.

Donald Trump continues publicly to suggest that diplomatic discussions with Iran remain possible while simultaneously warning that military operations could resume if negotiations fail. Israeli Prime Minister Benjamin Netanyahu has expressed considerable scepticism regarding the prospects for any durable agreement. Conflict has become an enduring feature of the investment landscape. The oil market reflects that reality earlier than most other asset classes because it sits at the intersection of economics and strategy. Ultimately, this conflict is no longer about the price of crude. It is about the price of control. Control over shipping lanes. Control over energy security. Control over strategic infrastructure. Control over the world’s most important economic arteries. As long as that control remains contested, energy markets will continue to price uncertainty rather than equilibrium. And in the new geopolitical order, uncertainty has become the world’s most expensive commodity.
