Why The Iran War Is Repricing Global Supply Chains

Oil at $120 is the headline, but the real story is what happens next: ships stop moving, insurance costs explode, fertilizer prices jump, and food inflation arrives right on schedule. We walk through the last month of fallout from the Iran conflict and explain why the Strait of Hormuz is more than a map detail. When a chokepoint that normally carries a huge share of global crude oil exports and LNG effectively freezes, the “price of energy” becomes the price of almost everything. 

We connect the dots across supply chain disruption and global trade: stranded or rerouted tankers, limited bypass capacity, higher freight rates, and the working-capital strain of longer voyages and bigger safety stock. Then we dig into the commodity layer, where fuel, fertilizer, and freight combine to raise landed food prices and intensify food security risk for importing regions. On the macro side, inflation expectations rise, rate cuts get postponed, equities sell off, and stagflation stops sounding like a history lesson. 

We also zoom out to the strategic questions driving the uncertainty: misjudged capabilities, unclear objectives, Russia’s leverage in higher energy markets, and why NATO politics and European legal constraints make allied alignment far from automatic. If you’re a supply chain leader, policymaker, or investor trying to plan under volatility, this conversation is a practical guide to what breaks first and what to redesign for resilience.

Hello, thanks for joining us today. Good to have you along. Tony Hines here, you're listening to Chain Reaction, the number one podcast all about supply chain advantage, global trade and policy. Subscribe to Chain Reaction, you'll be first to know when new episodes are out, and you'll never miss an episode! Well it's four weeks since the United States and Israel unleashed their attacks on Iran. And what's happened to world markets since? Well they're very volatile. Probably the most volatile they've been for many years, and of course it's having implications for supply chains around the globe. Essentially the United States is now buying in inflation. Any oil it purchases or gas purchases on world markets will bring with them inflation. But even if that doesn't do it, the tariffs that President Trump has placed on goods from many countries is also buying in inflation. And of course, other products coming from countries, for example, say Japan, where they have to pay much higher prices for oil and gas to fire up their industry, then those costs are being passed on too. So President Trump has unleashed unknown economic volatility on the United States and other countries. The bond markets in the United Kingdom are now approaching 5%. So any borrowing that the government makes will be more costly, and that will have implications for growth and GDP. The other interesting fact is the daily announcements that come out of the White House with contradictory statements. After the markets have closed in the United States every day, about fifteen minutes later, President Trump comes out, makes his announcements for the day, and tries to calm the markets because the markets are very volatile, and those statements are designed to try and bring oil prices down in the marketplace for short periods. And there have been hints that there's been insider trading too, taking place where some people have made huge profits and huge gains from acting on the statements of President Trump. But the fact is some of those purchases are taking place before the announcements are made. So they're betting, in a sense, on what Trump is going to do to lower the price. And when it happens, they've made a big gain in the marketplace. Well in summary, oil and gas prices, there's been a large supply shock. Straits of Hormuz disrupted, and Brent Crude is trading somewhere between$110,$120 presently, with high risk of further volatility. Shipping transiting through Hormuz has largely frozen. Insurance and freight costs have spiked, and there's high risk to the shipping in the area. Food and fertilizers, energy, fertilizer and freight prices are up sharply, and there's high risk of lag defects, so people are expecting those costs to go up further. In financial markets, equities are down, inflation expectations are up and rate cut cycles have been delayed. The risks are medium to high. And in the real economy, rising stagflation is on the horizon, especially for energy importing economies. And the risks are again medium to high. So that's a summary of where we are after a month of US policy to attack Iran. Let's take a deeper look. Energy markets and choke points. The Strait of Hormuz is the fulcrum. Around one fifth to one third of global crude oil exports and roughly 20% of LNG normally move through that strait. The conflict and effective freeze in transit volumes since early March have created the largest single oil and gas supply disruption on record. There's been price and volume shocks. Brent crude has moved from roughly$70 pre-crisis to above$120 and it has peaked higher than that, with Gulf export from Kuwait, Iraq, Saudi Arabia, UAE and Qatar curtailed by several million barrels a day as seaborne flows are stranded or rerouted via limited pipelines. LNG exports from Qatar have been hit hard, with force majeure declared on many of the contracts. The systemic consequence of all this, the International Energy Authority and others are already framing this as the most severe global energy and food security challenge since the 1970s energy crisis, with stagflationary dynamics, supply chain inflation, plus growth downgrades now for the central macro risks. In shipping, insurance and trade routes, there's been maritime disruption, with Hormuz closed, transit trades in the strait has effectively frozen, and that's hit crude oil supply and LNG supply and fertilizer supply, which we'll talk about in a moment. There have been diversions, tankers and some container services are rerouting where possible. For example, Saudi Arabia and the UAE pipelines to Red Sea ports, but that capacity is limited. We've talked about this before. It's at most at its very optimum point, it would be a fifth of the amount of oil that could pass through those pipelines. The insurance and risk premiums have gone sky high for vessels entering the Gulf, and some operators have suspended calls entirely, which pushes up freight rates for energy and bulk commodities. Working capital needs longer voyages, higher inventories and transit, and the barriers to entry for smaller shippers and traders who can't absorb the volatility is knocking them out of the market. It's having a knock-on effect to other corridors. As ships avoid Hormuz and some Gulf ports, pressure shifts to the Red Sea and sewers, overland pipelines and rail where available, and storage hubs in Europe and Asia which become strategic buffers rather than just throughput nodes. Commodities food and fertilizers are also going up. Higher oil and gas prices feed directly into fertilizer costs, especially nitrogen, heavily gas dependent, diesel for farm operations and transport, marine fuel for bulk carriers, moving grain and other staples. The early data is already showing rising prices for oil, gas and fertilizers as a bundle. Regional food security stress. The GCC states, which imports over 80% of their calories via maritime routes through Hormuz, are facing what some analysts call a grocery supply emergency. With 70% of food imports disrupted and retailers resorting to airlifting staples at huge cost, driving 40 to 120% price spikes for consumers. There are global spillovers for net food importers in Asia, Africa, and the Middle East. The combination of higher freight, fertilizer and fuel costs, the Holy Trinity, one might say, is raising landed food prices, increasing subsidy burdens for governments, and heightening social and political risk where food inflation is already sensitive. On the macro front, inflation and financial conditions. Inflation shock, the oil and gas spike is feeding into transport manufacturing and food prices globally. Energy importing economies in Asia and the EU are particularly exposed. There's a monetary policy pivot. Central banks that were preparing to cut rates in 2026 are now facing a dilemma. Cutting risks, validating higher inflation, and holding or hiking risks deepening a slowdown. Early commentary suggests rate cuts are being postponed and in some cases further tightening is back on the table. In financial markets, equity indices have sold off, with US benchmarks down and volatility up as investors price high energy costs and geopolitical risks into the goods. So premiums are going in to everything. So what we have going on here? We've got oil and gas value chains, upstream in the Gulf, curtailed production, and export constraints all happening. Downstream globally, refineries are facing feedstock uncertainty and margin volatility. And of course, if any of those oil plants close or have to shut down temporarily, it's not like a tap, you can't just turn it on and off. There has to be all kinds of maintenance checks and it takes time to get the oil plant re-going. In chemicals and plastics, we've got higher naphtha and gas-based feedstock costs, and we've got potential rationing and curtailment of energy intensive production, ammonia, methanol and polymers. In manufacturing and transport we've got automated, aerospace and electronics all hid with higher logistics and input costs, and the risk of demand softening if consumer real incomes are squeezed. In aviation and logistics the jet fuel cost is rising. The rerouting around conflict zones, those aircraft, increasing flight times and costs on some Asia Europe lanes much higher. In agriculture and food processing, we've got those fertilizer and fuel costs up, and especially in developing markets. So food prices are likely to get pushed up, so there's inflation coming in there too. And then there's supply chain reconfiguration, greater emphasis on regional sourcing and stockpiling of staples. Governments may intervene with export controls or subsidies, adding policy risk to supply chains. So while the elevated oil prices over a hundred dollars and gas and freight prices increase, there's persistent disruption in Homo's partial mitigation via alternative routes, but it's only partial. There's rising inventory and safety stock going up across critical sectors in energy, food and pharmaceuticals, and slower global growth with higher inflation. It's a classic recipe for stagflation. In the medium term six to twenty four months, if conflict stabilizers and tensions remain, there'll be rerouting and redundancy, more investment in pipelines bypassing whore moves, additional LNG capacity outside the Gulf, and diversification of sourcing, for example, more African and American suppliers for energy and food. Regionalization. Firms accelerate China plus one style strategies for the Gulf, for energy and petrochemicals, more capacity in the United States, Latin America and parts of Africa. And there's going to be a premium for resilience. It's going to cost more. Higher structural inventory levels, more multi-sourcing, and greater use of long-term contracts to secure capacity. All pushes up prices. If the escalation continues or widens, there's going to be deeper long-lasting energy and food price spikes, and more frequent government intervention, might be export bans, price controls, and even rationing. Higher probability of a global recession is driven by energy, shocks, and financial tightening. So a moving from efficiency to resilience, lean gestin time models anchored on cheap Gulf energy and frictionless choke points are being repriced. Redundancy, optionality, and geographic diversification become core to the design of our supply chains. Energy is a design constraint, and it causes price volatility as we've seen. And then there's policy and geopolitics taking center stage. Well let's take a look at why the war hasn't gone as well as expected. Everybody was critical at the start of this war, saying that the United States hadn't thought through the implications, and it certainly didn't have the strategic objectives clearly mapped out. And I think that's become fairly clear over the few weeks that this war has currently been going. I think they've underestimated Iran's capabilities. Iran's command and control would collapse quickly was the assumption. Its missile and drone capabilities were limited, another assumption. Its regional networks Iraq, Syria, Lebanon, Yemen could be contained. Its naval disruption capacity in the Straits of Hormuz was symbolic rather than operational. Well none of those have proved true. All of these assumptions are false. Iran has spent twenty years or more preparing for asymmetric conflict with a technologically superior adversary. Its strategy is built around distributed missile systems, redundant command structures, proxy and partner forces, and of course choke point disruption, which is what's going on right now, and resilience under sanctions. They've proved themselves to be very resilient. And we mustn't underestimate Russia's role in the whole process, which I think again the United States have done. It wasn't factored in. Moscow's provided intelligence, support and possibly targeting data, increasing military technical cooperation, used the conflict to stretch US bandwidth, and leverage the crisis to push energy markets in its favour because Russia is under sanction. But the war is really helping them now because they're able to generate revenue. For Russia, this conflict is a strategic gift. It raises oil prices, it weakens Western cohesion and diverts US attention. The administration's public messaging often treats Iran as an isolated country, and it isn't. Europe has been skeptical from day one. They think the United States has fundamentally misunderstood the purpose of NATO in its current administration. NATO is a defensive alliance, it's built on collective defense, not collective offense. It's designed to deter attacks on members, not support unilateral wars. It's dependent on consensus, not presidential direction. European governments have been clear, sometimes quietly, sometimes publicly. This is not a NATO mission. Article five is not triggered. The conflict does not meet NATO's criteria for collective action. The administration's frustration with NATO stems from a belief that allies should automatically support US military operations, and that's never been how NATO was designed, intended, or in fact how it works. European allies have been worried for several reasons. Energy exposure Europe is highly vulnerable to oil and gas shocks, the types that have been caused by this war. Economic fragility, inflation and slow growth make escalation dangerous. Diplomatic instincts Europe prefers to contain and negotiate. Regional stability, a wider Middle East war is a direct threat to EU security. Legal constraints many EU states require parliamentary approval for offensive operations. They can't just go to war on a whim with a presidential directive. From the European perspective, the United States moved fast, without consultation and without a clear plan for the day after. What happens next? Well, President Trump and the administration in the United States doesn't appear to listen. It isn't about personality, it's about structure. The administration's decision making style is highly centralized, driven by a small inner circle, suspicious of multilateral institutions focused on short term tactical wins rather than long term strategy. European leaders have repeatedly signaled concerns, but the White House strategic culture prioritizes speed over consensus, action over coordination, domestic political optics over alliance management, and there's the problem. It creates a widening gap between United States expectations and European willingness. The result strategic incoherence. When you combine underestimation of Iran, underestimation of Russia's involvement, misunderstanding of NATO's purpose, European reluctance, a faster moving conflict, a White House that prioritizes unilateral action, you get exactly what we're seeing contradictory statements, confused objectives, friction with allies, escalation without a clear end game. The dilemma now, of course, is where do we go from here? Well, President Trump says he's negotiating with Iran. Iran deny there's any negotiation taking place. And you have to look at this logically and ask the question, why would they bother right now? Because they've got everybody yeah, everybody choked up by the Strait of Hormoose. And whether they lay mines or said they've laid mines or do whatever they've said they've done The point is, no military commander would know whether that's true or false without investigating the seabeds. And can ships risk to go through there? Well no. Hostile territory insurance too high. Would you risk your million pound ships and million pounds of cargo on those ships going through a strait that's heavily armed and in a war zone? Well I think the answer's simple. You wouldn't. Only fools rush in where angels fear to tread. The longer this war goes on, of course, the more inflation there will be, the more energy shortages there will be, the more goods will go up in price, economies around the globe will be under pressure, economic growth will falter and may actually decline, reverse. And stagflation is a strong possibility. Will the markets want that? Well of course not. Markets like certainty. They don't like all this uncertainty, and this uncertainty happens every day now. One minute the oil price is up, sky high, the next minute it comes down a small amount, and it goes back up again. Spikes everywhere and people getting killed in the process. Two work and sound with the economic impact here, and what happens to supply chains, and what happens to global trade, and why this war will go down in history probably as a folly. Historians often label a war as a folly. They tend to earn the label when three conditions converge one misjudging the adversary. Two misreading the international system. Three acting without a coherent end state. Wars become follies when leaders launch them quickly, expect rapid victory, fail to define what success looks like, and have no plan for the day after. I think you'll agree all those criteria are present here. There's geopolitical miscalculation, Russia's support for Iran, European reluctance, shaped by the energy exposure, economic fragility, legal constraints, a preference for containment, and a lack of consultation from Washington. This war already carries the DNA of a historical mistake, a misread of economic impact, a misread of domestic and international political constraints. Where this leaves the United States and its allies? Well the tragedy is that none of this was inevitable. The signals were visible before this war started. Iran's capabilities were known, Russia's alignment was predictable. NATO's limits were clear. Europe's skepticism was voiced early. The economic risks were widely understood. But the administration's decision making style, centralized, improvisational, dismissive of allied input, means all those signals were not heeded and incorporated in any strategy. Well that's it for this special episode. Taking a look at what's happening almost a month after the war, launched by the United States and Israel on Iran is underway. Until next time, I'm Tony Hines, I'm signing off. Take care, bye for now.
