Chokepoints, Bottlenecks and Disruption
Six weeks ago, the world was awash in oil and related products. Supply was ample, inventories were adequate, and prices were low and stable. In many ways, energy markets looked like the least of investors’ concerns. That changed quickly.
Tensions in the Middle East escalated sharply following U.S.-Israeli airstrikes against Iran, triggering one of the most abrupt and consequential supply disruptions in decades. Energy prices surged as Iran moved to restrict exports from the region—most notably through its effective closure of the Strait of Hormuz.
That chokepoint is not just a regional issue; it is a global one. If energy products cannot move freely through the Persian Gulf for an extended period, the ripple effects would be severe enough to tip the global economy toward recession. Despite a recent ceasefire, markets remain on edge as the economic fallout continues to unfold.
Scared strait
The massive air campaign conducted by the United States and Israel has significantly degraded Iran’s air defense systems and military infrastructure. Even so, Iran retains meaningful economic and geopolitical leverage—largely because of its control over the Strait of Hormuz as well its ability to damage energy infrastructure across the region.
Approximately 100 miles in length, the Strait of Hormuz is a narrow maritime corridor connecting the Persian Gulf to global shipping lanes serving both Europe and Asia. Iran borders the entire northern coastline of both the strait and the gulf itself. At its narrowest point, the strait is just 24 miles wide. But the usable shipping lanes are far tighter: two channels—one inbound and one outbound—each about 2 miles wide, separated by a 2-mile buffer.
The full transit takes 8–10 hours, leaving slow-moving tankers exposed for extended periods. High traffic density (roughly 60 tankers per day pre-conflict) and limited maneuverability mean that even a single disabled vessel can halt traffic. In such confined space, relatively unsophisticated weapons—mines, drones, or small attack boats—can be highly effective. The mere threat of such low-level attacks has slowed shipping to a trickle.
Barrel racing
Approximately 20 million barrels of oil per day move through the Strait of Hormuz—about 20% of global consumption. While some volumes can be rerouted via pipelines to the Red Sea, that capacity is limited and itself vulnerable to drone attack. With storage constraints across the region, producers have already begun shutting in production.
The strait is also a key transit route for liquefied natural gas (LNG), accounting for about 20% of global LNG trade—primarily from Qatar. However, because Gulf LNG represents a smaller share of total global gas production, the impact there is more contained than in oil.
The effects are already visible. Asian economies are experiencing conditions comparable to the 1970s energy crisis, with fuel rationing emerging in some countries. There are no gas lines in the United States. However, it is not immune to the disruption despite being the world’s largest oil producer and a net exporter—oil is priced in a global market. West Texas Intermediate crude surged from around $60 per barrel pre-conflict to over $100 in early April.
Prices for refined petroleum products have also jumped significantly. Average U.S. gasoline prices have risen above $4.00 per gallon from under $3.00. Diesel—powering trucks, trains, ships, and heavy equipment—is up roughly 80%. And jet fuel prices have doubled.
Beyond energy
The disruption is no longer confined to oil and gas—it is cascading across broader commodity markets, impacting global manufacturing and agriculture sectors.
Petrochemicals, derived from oil and natural gas, are basic inputs for a wide array of goods—from plastics and packaging to pharmaceuticals and textiles. The Gulf region is a critical supplier. For example, Qatar alone provides around 35% of global helium, essential for semiconductor manufacturing and medical imaging. Prices have already doubled.
The region is also central to global fertilizer production. It accounts for over 40% of global urea and sulfur and roughly 30% of ammonia. These are key inputs for modern agriculture. As prices rise and supply tightens, farmers are being squeezed from multiple directions—higher fertilizer costs, limited availability, and surging diesel prices during peak planting season. The likely result: reduced application rates and lower crop yields, setting up a potential wave of food inflation.
Second order effects
Energy shocks rarely stay contained—they flow through the broader economy and impact financial markets. For consumers, higher fuel and utility costs function like a tax, reducing discretionary spending. This is particularly impactful for lower-income households, where energy represents a larger share of total expenses. Slower consumption growth translates into slower GDP growth.
For businesses, rising input, transportation, and raw material costs compress margins. Companies may attempt to pass these costs on, but that risks further dampening demand. Either way, earnings come under pressure.
In addition, inflation could broaden out. Today’s energy shock becomes tomorrow’s food inflation via fertilizer shortages and reduced crop yields. In the services sector, higher jet fuel costs are already pushing up airfares and reducing flight availability.
Ordinarily, policymakers would respond to slowing growth with easier monetary policy. But the current backdrop complicates that response. Inflation—already sticky—has been exacerbated by the energy shock, limiting the Federal Reserve’s flexibility. Before the conflict, markets expected two interest rate cuts in 2026. Today, expectations have shifted toward no cuts at all.
Lawyers, guns and money
On April 7th, the United States and Iran agreed to a two-week ceasefire to allow time for negotiations. In exchange for a halt to military strikes, Iran has begun allowing limited shipping through the Strait of Hormuz. However, the agreement appears very fragile—more a loosely defined truce than a durable resolution to the conflict.
It is impossible to gauge how long the supply disruptions will persist. But both sides have incentives to de-escalate. For the administration, with midterm elections looming, political pressure is rising as higher energy prices impact consumers. For Iran, its leverage is tied directly to its ability to unsettle global markets—and by extension, influence economic and political outcomes abroad. That clock is ticking.
Despite the uncertain backdrop, oil markets are signaling an expectation that bottlenecks will prove temporary. Oil futures prices for delivery later this year remain meaningfully below near-term prices, suggesting traders believe supply will normalize in the coming months.
Temporary shock or lasting shift
For investors and the broader economy, the key question is not just whether this shock ends—but when. If the disruption proves short-lived—resolved in a matter of weeks rather than months—the damage may be contained. Energy prices would likely retrace, inflation pressures could ease, and the Federal Reserve might regain some flexibility to support growth. In that scenario, this episode would resemble a sharp but temporary shock—impactful, but ultimately manageable for both the economy and financial markets.
But there is a tipping point. The longer the disruption persists, the more it embeds itself into the fabric of the global economy: Supply chains are reconfigured, businesses reset pricing and cost structures, consumers adjust spending behavior, and inflation expectations become less anchored. At some point, the damage cannot be fully reversed. The shock would have already transitioned from cyclical to structural—raising the prospect of slower growth, more persistent inflation, and tighter financial conditions.
Markets, for now, are betting on a relatively quick resolution. As is often the case, the path forward may hinge less on the initial shock—and more on how long it lingers.
