US-Iran Hormuz Deal Cuts Oil Prices 8% as Tanker Traffic Resumes

The deal reverses Iran's March 2026 closure of the strait after prior sanctions escalation. Primary records show daily tanker transits rising from near zero to 42 within 72 hours per AIS tracking data. This directly increases Gulf crude and LNG supply to Asia and Europe, pressuring OPEC+ quota discipline and US shale export margins. Iranian incentives center on sanctions relief and frozen asset access, while US gains include lower inflation readings and reduced pressure on strategic petroleum reserve drawdowns. The arrangement leaves no formal verification mechanism for military transit, creating enforcement ambiguity that both sides have historically exploited during prior JCPOA disputes.

Energy market data reveals immediate contango flattening in prompt WTI contracts and a 12% rise in VLCC bookings to East Asia. European natural gas futures fell 9% on expected Qatari LNG rerouting, tightening the link between Hormuz flows and eurozone CPI components. Chinese state importers have already locked in additional June cargoes at the lower prices, illustrating the rapid reallocation of physical barrels away from Atlantic basin destinations.

The absence of parallel commitments on enrichment caps or ballistic missile limits indicates the deal prioritizes energy throughput over broader nonproliferation benchmarks. Follow-on effects will appear first in July CPI prints and central bank policy divergence signals. Absent renewed closure threats, risk-asset correlation with geopolitical premia should compress further through Q3.
