Impact of Strait of Hormuz Closure on Jet Fuel Supplies

Goldman Sachs warns Europe’s aviation sector faces a 15% flight reduction this summer due to the Strait of Hormuz closure disrupting jet fuel supplies. Analyst Michele Della Vigna cites “demand rationing pricing” as the mechanism to rebalance markets, with fuel costs rising until demand contracts. The squeeze hits Lufthansa (ETR: LHA), Air France-KLM (EURONEXT: AIR) and budget carriers hardest, while shippers and manufacturers grapple with secondary inflationary pressures.

The Bottom Line

• Flight capacity cuts: Europe’s airlines must slash 15% of summer schedules to offset fuel shortages, with Ryanair (NASDAQ: RYAAY) and easyJet (LSE: EZJ) most exposed due to high short-haul exposure.
• Fuel cost pass-through: Jet fuel now accounts for 30-35% of airline COGS; a 50% price spike (as implied by Goldman’s rationing model) would erode Lufthansa’s 2025 EBITDA margin from 8.2% to 3.1%.
• Supply chain spillover: Shipping costs for perishables (e.g., fresh produce) could rise 12-18% as air cargo reroutes, hitting Maersk (CPH: MAERSK-B) and DHL (FRA: DHL) margins.

Why This Matters: The Fuel-Price Feedback Loop

The Strait of Hormuz closure—now in its 12th week—has tightened global oil flows, but jet fuel’s unique refining path creates a bottleneck. Here’s the math:

• Refinery arbitrage collapse: Middle East refiners typically export 1.2M barrels/day of jet fuel to Europe. With the strait closed, European refiners must source from the U.S. Gulf Coast (a 3,000-mile detour), adding $15-20/bbl to costs.
• Goldman’s rationing mechanism: Della Vigna’s 15% flight cut assumes fuel prices rise to $1,200/ton (from $850/ton in April). At that level, IAG (LSE: IAG)—owner of British Airways—would see its 2026 fuel bill jump from €6.2B to €9.3B.
• Regulatory blind spot: The EU’s Emissions Trading System (ETS) adds €10/ton to fuel costs. With airlines already paying €80/ton in ETS allowances, the dual squeeze forces capacity cuts over price hikes.

Market-Bridging: Who Wins, Who Loses?

This isn’t just an airline story. The ripple effects hit three sectors:

1. Airline Stocks: The Margin Death Spiral

Legacy carriers face structural pain, while low-cost rivals pivot to niche routes. Here’s the stock performance snapshot (as of May 17, 2026):

Jet Fuel Supplies Lufthansa

Company	Ticker	YoY Stock Change	2026E EBITDA Margin	Fuel Cost as % COGS
Lufthansa	ETR: LHA	-22.4%	3.1% (vs. 8.2% 2025E)	34.7%
Ryanair	NASDAQ: RYAAY	-18.9%	18.3% (hedged fuel)	28.1%
Air France-KLM	EURONEXT: AIR	-25.1%	4.8% (vs. 9.5% 2025E)	32.9%
IAG	LSE: IAG	-15.7%	12.4% (vs. 16.8% 2025E)	31.5%

Key insight: Ryanair’s hedging strategy (locking in 70% of 2026 fuel at $750/ton) buys it time, but its high-load-factor model (85%+) leaves little room for further yield cuts.

2. Shipping and Logistics: The Air-Cargo Exodus

With airfreight capacity down 20% (per IATA), shippers are scrambling.

“We’re seeing perishable cargo rerouted to sea, but vessel rates on the Europe-Asia lane have already spiked 30% since April,” said Henk van Hoof, CEO of DHL Global Forwarding. “The real risk is spoilage—fresh produce from Kenya to Europe now takes 10 days instead of 4.”

This benefits Maersk (CPH: MAERSK-B), whose container ships now carry 15% more air-cargo-equivalent volume, but at a cost: its 2026E operating margin drops from 18.5% to 15.2% due to bunker fuel surcharges.

3. Inflation: The Hidden Tax on Consumers

Jet fuel isn’t just a corporate expense—it’s a demand destroyer. The ECB’s May 2026 projections now include a 0.3% upward revision to 2026 H2 inflation, driven by:

• Tourism drag: European leisure travel demand falls 5-7% YoY, cutting GDP growth by 0.2-0.3 percentage points (per IMF WEO).
• Business travel collapse: Corporate jet bookings drop 25% (per IATA), hitting American Express (NYSE: AXP) and Visa (NYSE: V) transaction volumes.
• Secondary inflation: Air cargo delays push up food prices in Southern Europe by 2-4% (e.g., Spanish tomatoes +3.8% in April, per Eurostat).

The Geopolitical Wildcard: Can the Strait Reopen?

Goldman’s base case assumes no reopening by summer, but three scenarios emerge:

1. Diplomatic resolution (30% probability): A temporary truce (e.g., Iran-U.S. Backchannel talks) could reopen the strait by June 15. Jet fuel prices would drop 30% in 30 days, but airlines would still face capacity constraints due to crew shortages.
2. Prolonged closure (50% probability): Fuel prices stay elevated, forcing Europe to import more U.S. Shale-derived jet fuel. ExxonMobil (NYSE: XOM) and Chevron (NYSE: CVX) stand to gain $12B-$15B in incremental refining margins.
3. Escalation (20% probability): A conflict disrupts Saudi Arabia’s oil flows, sending Brent to $120/bbl. European airlines would file for state aid, as seen in 2022.

Expert take:

“The market is pricing in a 40% chance of a $1,500/ton jet fuel floor by July,” said Andrew Lipow, president of Lipow Oil Associates. “That’s not sustainable for long-haul carriers like Emirates (Dubai: EMIRATES) or Qatar Airways (QSE: QATR), which rely on fuel hedges expiring in Q3.”

Actionable Takeaways for Investors

1. Short airlines, long refiners: Bet against legacy carriers (e.g., Delta (NYSE: DAL), United (NASDAQ: UAL)) and overlay calls on Valero (NYSE: VLO) (jet fuel crack spreads widen).

2. Hedge supply chains: Companies with air-cargo exposure (e.g., Amazon (NASDAQ: AMZN), Zalando (FRA: ZAL)) should lock in 6-month freight contracts now.

3. Watch the ECB: If inflation ticks up 0.5%+ in June, the ECB may delay rate cuts, pressuring European corporates. Siemens (ETR: SIE) and SAP (NYSE: SAP) CFOs have already warned of margin compression.

The Bottom Line: A Summer of Pain, Not Collapse

Europe’s aviation sector won’t collapse, but the 15% flight cut is a floor, not a ceiling. The bigger risk is the secondary damage: higher shipping costs, delayed goods, and a tourism slowdown that drags on Q3 GDP. For investors, the playbook is clear—short the exposed, hedge the supply chains, and prepare for a prolonged bout of fuel-driven rationing.
