Strait of Hormuz Flows Down 30%; Iran War Inflation Shock Lifting Oil and Pressuring Growth

The Middle East conflict has morphed from a headline risk into a structural energy supply shock. The Strait of Hormuz, which handles roughly 20-25% of global crude flows under normal conditions, has seen traffic plummet by nearly 6 million barrels per day in the first quarter of 2026, a collapse equivalent to losing the entire output of a major OPEC producer overnight. Shipping companies are routing around the region, adding time and cost to energy transport; insurers are demanding premium rates for ships traversing the region. The cumulative effect is a persistent elevation in crude prices, now feeding through to downstream inflationThe rate at which prices rise across an economy. in energy-intensive sectors like transportation, utilities, and basic materials.

Air New Zealand, already under margin pressure from fuel surges, expects a substantial full-year loss as jet fuel costs spike in tandem with crude. Senegal announced a $7.5 billion gas project designed to end dependence on energy subsidies, a clear sign that energy scarcity is reshaping capex priorities across the globe. The EIA reported flows fell 30% in Q1; absent a rapid de-escalation in the Iran conflict or a breakthrough in diplomatic talks, the supply shock will persist through summer.

The inflationThe rate at which prices rise across an economy. pass-through is visible in both headline and core CPI prints, complicating the Fed's policy calculus. While Powell's Fed might have looked through temporary energy shocks, the cumulative 6% PPI rise and sticky core readings are making it harder to justify a swift pivot to rate cuts. This dynamic favours defensive sectors (utilities, staples, healthcare) with lower energy exposure and pricing power, while pressuring unprofitable growth stocks (SaaS, biotech pre-approval) that depend on low-rate financing. Energy stocks and commodities are rallying; Fervo Energy's $1.89 billion geothermal IPOInitial Public Offering - a company's first public sale of stock. at a 33% first-day pop reflects investor enthusiasm for supply-side solutions to energy inflation.

The counter-argument hinges on demand destruction. If crude prices remain elevated, consumers and businesses will cut energy consumption, demand will soften, and prices will eventually normalize. Renewable energy deployment (solar, wind, geothermal) could accelerate faster than historical norms if energy costs remain high. However, near-term (next 3-6 months), the energy shock is a structural headwind for growth equity valuations and a tailwind for rate volatility and real assets.
