When Prices Break from the Map

The fourth week of the Iran conflict has pushed crude oil prices higher and drawn predictable attention to Brent, yet that framing misses the more important shift underway, as this is not simply an oil price shock but a breakdown in the idea of a single global price.

Energy markets are beginning to fragment, with prices no longer set by a common equilibrium but by access, logistics and security, and the Strait of Hormuz emerging as the dividing line, where what can move through it, and what cannot, now shapes price formation as much as supply and demand. 

West Texas Intermediate trades near $98 and Brent crude around $112, yet crude available to Asian importers is significantly more expensive, with Dubai near $135 and Oman closer to $160, leaving a gap of as much as $60–65 between benchmarks that are theoretically linked, reflecting not a temporary dislocation but a market splitting along corridors.

A similar pattern is evident in natural gas, where European prices remain elevated near €60 per MWh even as gas in parts of the US has traded at negative levels, underscoring that the constraint lies not in production but in infrastructure and routing, so that supply exists but cannot reach where it is needed, and energy is no longer fully fungible or globally priced.

Routing Risk
This fragmentation becomes clearer when one looks beyond spot prices to the economics of transit, since oil cargoes are typically booked months in advance, and shipments contracted before the conflict have found themselves delayed or exposed, even as ownership has already transferred, leaving buyers to bear replacement costs if cargoes are disrupted.

Insurance premiums have risen sharply, from about $1–2 per barrel to $6–8, while additional payments for safe passage through contested routes have further increased costs, and even cargoes priced at pre-conflict levels now carry embedded risks that push effective landed costs much higher, with Asian importers sourcing via alternative routes already facing all-in costs in the $140–150 range, and higher for certain grades, so that what appears as a moderate move in global benchmarks becomes a much sharper increase in realised import costs.

This shift reflects corridor-based pricing, where the marginal barrel is no longer defined by extraction cost alone but by the security and viability of the route it must travel.

Even if hostilities ease, this reset is unlikely to unwind quickly, as oil wells that are shut take time to restart, and the episode has exposed the limits of strategic reserves and the fragility of supply chains, prompting importing countries to rebuild inventories and sustain demand even as supply conditions improve.

That, in turn, suggests a floor under global benchmarks and a persistence of regional spreads, where the gap between Brent and Middle Eastern grades may narrow but is unlikely to disappear, because the mechanism of pricing itself has shifted, with markets behaving less like integrated systems and more like segmented ones.

Cost Transmission
In such a system, cost shocks tend to persist because they are no longer arbitraged away quickly across regions, and what begins as an energy disruption is already moving into food and manufacturing costs, creating a broad-based, input-led inflation impulse.

Fertilisers provide the most immediate channel, with a significant share of global urea and sulphur trade passing through the Gulf and disruptions already tightening availability, pushing prices higher and feeding directly into food systems.

India’s exposure is material, as while domestic production meets a large portion of demand, the system depends on imported feedstock such as natural gas, phosphoric acid and ammonia, and although inventory buffers offer some near-term cover, the timing is unfavourable, with the kharif season approaching alongside early indications of an El Niño, raising the risk that input constraints coincide with weather uncertainty and allowing food inflation to rise even without a corresponding demand impulse.

Chemicals reflect a similar transmission through industrial costs, with higher crude and gas prices lifting the cost of naphtha and other feedstocks and pushing up prices across polymers and intermediates, feeding into sectors such as automobiles, pharmaceuticals, packaging and consumer goods, where producers face margin pressure when costs rise faster than pass-through, and where pass-through does occur, it is likely to show up as broader core inflation rather than isolated spikes.

Even niche inputs point to the depth of the disruption, as helium, heavily sourced from the Gulf, has seen supply interruptions that are beginning to affect healthcare diagnostics and semiconductor manufacturing, illustrating how deeply energy-linked supply chains run across sectors.

For policymakers, this presents a more complex challenge than a standard commodity cycle, since rate adjustments address demand conditions rather than the fragmentation of supply, and strategic reserves can smooth temporary shortages but do not resolve routing risks or infrastructure bottlenecks, complicating the inflation response as central banks face persistent cost-push pressures that are not demand-driven.

The more durable adjustment lies elsewhere, in diversification of sourcing, investment in logistics and storage, and closer coordination between energy, trade and industrial policy, as supply chains become less reliable and more politically mediated.

What has changed in this episode is not just the level of prices but the way they are formed, with markets no longer clearing at a single global equilibrium and instead being shaped by corridors, constraints and control points.

For energy-importing economies, the question is no longer how high prices will go, but how reliably supply can be secured and at what structural cost, with inflation becoming less a cyclical outcome and more a function of how effectively economies can navigate these fractured supply lines.
