Key Takeaways:

• Strait of Hormuz disruptions extend well beyond oil, impacting global supply chains.
• The most notable transmission is into agriculture, where constrained fertilizer supply is raising input costs and reshaping crop dynamics.
• Third-order commodity effects may drive broader inflation and create uneven sector outcomes.

The Strait of Hormuz carries roughly one-fifth of the world's seaborne oil and LNG trade. When traffic through this corridor falls — as it has sharply since early March 2026 — the effects don't stay contained to energy markets. They ripple outward in ways that many investors haven't fully priced.

Highlights from the conversation:

• The disruption is real and structural — What began as a short-term energy story has evolved into something longer-term. The scale and duration of this disruption look meaningfully different from recent history, and the repercussions may fundamentally reshape the global economy.
• Alternative routes are ramping, but capacity is limited — Crude loadings at Yanbu on Saudi Arabia's Red Sea coast have risen sharply as flows reroute away from the strait. But existing infrastructure can only partially offset the disrupted Gulf export volumes, and a recent Iranian missile strike on Yanbu underscores how fragile even these workarounds remain.
• LNG and natural gas prices are surging — European TTF gas prices have spiked to levels not seen since the Russia-Ukraine conflict, reflecting tightening global LNG supply. Disruptions to Qatari exports, including Qatar Energy's declaration of force majeure, are a key driver, with downstream consequences extending well into chemical and fertilizer supply chains.
• Refining margins are spiking — European crack spreads have surged well above historical ranges, signaling acute product market tightness as crude flows and refining inputs are disrupted simultaneously.

The Agricultural Transmission: From LNG to the Farm

The concentration of chemical and fertilizer production in the Persian Gulf reflects the region's abundant, low-cost natural gas, which serves as both an energy source and a raw material feedstock for producing nitrogen, ammonia, and downstream fertilizer products. When that gas supply is disrupted, the effects move directly into agriculture.

Qatar alone produces roughly 5.5 million tons of nitrogen urea per year through QAFCO — the world's largest single-site urea exporter — and that output is now effectively zero following force majeure. With no overland export alternative and storage buffers measured in weeks, the clock is ticking. Meanwhile, Iranian drone strikes on Qatar Energy's principal production hubs have halted LNG output and shut down downstream chemicals and methanol production. The conflict has removed close to 40% of global nitrogen trade from the market, with an estimated 1 million tons of fertilizer physically stranded in the strait.

U.S. Gulf fertilizer prices are already responding. Nitrogen prices have risen more than 50% from pre-war levels, approaching levels seen during the Russia-Ukraine conflict. Phosphate has also moved higher, though the more immediate pressure is a margin squeeze: rising sulfur and ammonia input costs — with sulfur prices exceeding $550 per ton, more than triple year-ago levels — are compressing producer margins even as output prices increase. Potash remains the least affected nutrient, with its major supply basins in Canada, Belarus, and Russia sitting outside the conflict zone.

Second and Third-Order Effects: Crops, Food, and the Broader Economy

The timing matters enormously. Most U.S. and European farmers likely secured their nitrogen needs for spring planting before the conflict escalated. But Brazil is a different story. The country sources over 40% of its nitrogen from the Persian Gulf and is currently planning its spring season. If the disruption extends into the second half of 2026, Brazilian farmers may pull back on corn, a nitrogen-intensive crop, with knock-on effects for ethanol, biofuels, and potentially sugar, as processors flex cane production toward fuel.

Indian nitrogen producers are already curtailing output as the loss of Qatari LNG forces plant shutdowns and pulled-forward maintenance. India is the world's largest single nitrogen importer and depends on LNG imports to run its own production facilities.

Beyond fertilizers, there are several additional areas to watch: aluminum and helium exports from the Gulf represent roughly 10% of global trade each; Indonesian nickel production faces sulfur shortages; and the broader inflationary impulse from higher energy and food costs points toward a stagflationary macro backdrop. Globalization as we knew it may be effectively over, with countries increasingly prioritizing supply chain resilience over efficiency. This represents a structural shift with lasting implications for energy, defense, manufacturing, and AI infrastructure costs.

The Equity Opportunity: Where the U.S. Stands Out

Not all markets are moving in lockstep through this cycle, and that divergence creates both risks and opportunities. U.S. nitrogen producers are structurally advantaged: their production costs are pegged to Henry Hub natural gas, which remains cheap relative to global benchmarks, while their revenues are priced off global nitrogen prices that have surged. That spread has widened dramatically since the conflict began. European producers face the opposite dynamic as rising output prices are offset by surging TTF-linked feedstock costs.

Energy equities more broadly are benefiting from the price windfall, though ramping U.S. production meaningfully takes nine months to a year, meaning the near-term supply gap is not easily filled. OPEC increases have been modest. For investors, the more durable opportunity may lie in diversified resource equity strategies that can capture exposure across oil and gas, agriculture, and metals and mining as these dynamics continue to unfold.

Despite macro tailwinds, energy and materials sector valuations remain at or below their 10-year medians on EV/EBITDA, while offering above-median free cash flow yields and dividend yields, suggesting the market has not yet fully priced the structural shift underway.
