Iran War Closes Strait of Hormuz; Oil Near $80 as 20% of Global Flow Disrupted

The Strait of Hormuz closure has become the defining supply shock of Q2 2026. China is demanding rapid reopening of the waterway that handles one-fifth of global oil flows, but war resolution remains at an impasse. Bloomberg sources indicate Dow Chemical is "hardly moving anything" through the strait, with logistics delays potentially stretching to 275 days for alternate routes. This supply disruption is feeding directly into global inflationThe rate at which prices rise across an economy. expectations, with Japan's producer prices jumping 12 years' high in April and US bond markets repricing rate-cut timelines downward.

Oil prices reflected the structural constraint: WTI and Brent both headed for weekly gains as the conflict persists. The UAE announced it is building a Hormuz-bypass pipeline due for 2027 completion, signaling the region's expectation that the blockade will persist for months, not weeks. This long-durationBond price sensitivity to interest rate changes. shock differentiates the current regime from brief flare-ups; it is not a tactical pause but a strategic closure, and downstream energy users are hedging accordingly. Industrial companies reliant on fuel (airlines, logistics, chemicals) are absorbing margin hits or passing them to consumers via surcharges.

InflationThe rate at which prices rise across an economy. dynamics ripple across asset classes. US Treasuries sold off alongside global government bonds as investors repriced terminal rate expectations upward. Japan yields rose to multi-year highs. The Bank of Japan's recent hawkish signals (producer price jump backing a potential policy hike) are now intertwined with crude, not just local monetary policy. Copper extended its retreat from record highs as a stronger dollar and elevated real rates reduced attractiveness for EM importers.

The debate hinges on alternative supply: OPEC+ capacity offline, U.S. Strategic Petroleum Reserve being exported (nearly half is going to foreign buyers, indicating global desperation), and Russia's continued sanctions-evasion. If the war extends into Q3, oil could remain elevated and force central banks to tolerate stagflationary pressure (high growth expectations from AI capex, but high nominal rates from inflationThe rate at which prices rise across an economy.). Energy exporters (Norway, Brazil) benefit structurally, but energy importers (Europe, India, Japan) face recession risks if crude stays above $80.
